A case of Pb poisoning is presented in a 3-yr-old
boy who was  admitted to the hospital in a comatose
condition, with subsequent convulsions.  The diag-
nosis was obscure until basophilic stippling of the
erythrocytes, the Pb line in the long bones, as
seen in X-ray studies, were noted.  The patient
was treated by administration of Ca gluconate and
vitamins C and D in order to promote storage of Pb
in bones.  The child was discharged in good physi-
cal condition 45 days after admission to the hos-
pital.

Thirty-eight cases of Pb poisoning treated by BAL
are presented.  The intoxications were caused by
products having a Pb arsenate base.  All the clas-
sical symptoms described until the present time
were seen.  The author emphasizes the radiologic
aspect of the bones in the course of the intoxica-
tion:  the phenomena resemble those described re-
cently by R. Clement and his coworkers in nursing
infants fed by syphilitic nurses treated with Bi
injections although the opacities were less dense
and less precise.  In discussing  BAL therapy in
Pb poisoning, the author refers to the work by
Hesse in 1940 who believed that an antidote for Pb
should be a substance which would cause the elim-
ination of the poison by transforming it into non-
toxic salts.  This work was carried out with aro-
matic compounds containing phenyl hydroxyl groups.

        OPATHY WITH BAL (2.3-DIMERCAPTOPROPANOL).
        Pediatrics 5:853-68 (May),  1950.
Sixteen children with Pb encephalopathy  admitted
and treated with BAL in the past 3 yr were divided
into 2 categories according to the degree of se-
verity of illness.  The criteria were repeated
convulsions which were difficult to control, stu-
por or coma which persisted for longer than would
be consistent with the usual postconvulsive state,
ie, >12 hr, for severe category.  Using these cri-
teria 9 were severe and 7 mild.  For control, 31
children treated between 1943-1947 (with citrates
and phosphates) were used; in this group there
were 18 severe and 13 mild cases.
  BAL was injected im as a 10% solution in benzyl
benzoate in oil at a dose of 2 mg/kg every 4 hr
for 4 injections, and the dosage was increased to
3 and later to 4 mg/kg/injection every 4 hr for 10
days.  Several cases received shorter courses of
treatment.  No severe toxic effects were noted at
this dosage.  Some postinjection vomiting was seen
but it was not severe enough to cause discontinu-
ance of the therapy.  The mortality rates and evi-
dences of permanent nervous system injury in the
BAL group were 2 deaths out of 9 severe cases
against 12 out of 18 in the control group and
neurologic residua in total of 6 and 13, respec-
tively.  Blood Pb concentration fell in each case
irrespective of treatment and was  not influenced
by BAL administration.  Urinary excretion checked
coincidently with blood levels generally showed
increase at first but in some cases returned to
normal (pretreatment levels) during the treatment.
  The authors conclude that although BAL is ap-
parently effective in lowering the mortality rate
in children with severe Pb encephalopathy, no con-
clusive effects of therapy could be demonstrated
in subacute or mild cases.  (15 references)

The case of an infant is reported who was breast
fed for 3 mo and started suffering in his 5th
mo from unexplainable diarrhea and anemia.  After
cessation of diarrhea the anemia continued unin-
fluenced by treatment.  At the age of 13 mo Pb
poisoning was suspected.  Although there was no
stippling of red blood cells and no increase of Pb
in the urine, a diagnosis of Pb poisoning was
reached on account of X-ray findings in the long
bones.  It could be proved that the baby's mother
had used a Pb-containing ointment against cracks
in her nipples at the time of breast feeding.

Another case is mentioned of acute Pb poisoning
from use of a Pb nipple-cap.  The author warns
against the use of Pb-containing ointments as well
as Pb nipple-caps in the treatment of cracked nip-
ples.  (From Biological Abstracts 26:15257, 1952)

        BARRING USE OF PAINT CONTAINING LEAD FOR
        INTERIORS OF HOUSES.  Industrial Health
        Monthly 11:171 (Nov.), 1951.
Because 83 children have died of Pb poisoning in
the last 20 yr, Baltimore has passed a new housing
regulation barring the use of paint containing Pb
pigment for use in the interior painting of any
dwelling or dwelling unit or any part thereof.
From Jan. 1, 1931, to June 30, 1951, a total of 293
cases of Pb poisoning was reported.  Of these, 83
died.  The majority of the cases occurred in the
summer months, July and August.  While most of the
children were in their 2nd yr of life and so of
teething age, the reporting of most of the cases in
the 2 hot summer months is as yet not easily ex-
plained.  Usually children lived in old rented
properties where Pb paint had been used for many
years on window sills and frames where it had often
flaked and scaled.  Investigations made by the
nurse assigned to the Bureau of Industrial Hygiene
most often revealed that the children chewed the
window sills or picked up the paint flakes and put
them in their mouths.  Of the 293 cases, 93 were
white and 200 colored, 157 were male and 136 fe-
male.  By ages, 19 were <1 yr old, 167 were in
their 2nd yr, 67 in the 3rd, 21 in the 4th, 11 in
the 5th, and 8 were >5 yr of age.  Repeated warn-
ings about this child health hazard have been given
by the Baltimore City Health Department in the
press, by radio and television, and in other ways,
but more cases a-e being discovered as the years
go by.  Because of this, the new regulation was
adopted by the Commissioner of Health on June 29,
1951.  According to Baltimore's "The Evening Sun,"
for August 8, 1951, a landlord was fined in Housing
Court "for failing to remove from window sills Pb
paint which, according to testimony, had kept a 4-
yr-old boy in Johns Hopkins Hospital since June
21."  Dr. Wilmer H. Schulze of the City Health De-
partment said that up to Aug. 29 Baltimore has had
44 cases of Pb poisoning in children this year
"practically all in old houses in the lower income
group."  Eight of the children died.  Physicians
and hospital authorities are assisting in this
battle for prevention and the public health nurses
and housing inspectors do likewise as they make
their home visits.  A most important element is
the specially equipped blood Pb laboratory service
which was 1st established in the Baltimore City
Health Department in July 1935.

                         REN.   REPORT OF FIVE CASES, WITH SPECIAL
                         REFERENCE TO PICA.   British Medical Journal
                         1:329-34 (Feb. 17),  1951.
                 Of the 5 cases of Pb poisoning,  4 were associated
                 with pica and  1  was caused  by the use of a Pb nip-
                 ple shield.  The serious prognosis of the condition
                 is stressed.   One of the patients died and 2 appear
                 to be mentally backward.
                   The sources  of Pb in such cases can be broadly
                 divided according to the ages of  the  patients,   (1)
                 In infancy,  due  to Pb nipple-shields  or the use of
                 Pb-containing  powders, etc;  (2)   1-5  yr, due to
                 pica, eating Pb  along with  other  noxious substances;
                 most commonly  this is in the form of  Pb paint;  and
                 (3)  schoolchildren, due to accidents similar to
                 those met with in adult life.
                   The clinical features of  Pb-poisoning are dis-
                 cussed.  The manifestations in childhood differ
                 from those in  adults in that encephalopathy, with
                 irritability,  fits, and coma, is  very common.
                 Wrist-drop and the Pb line  on the gums, however,
                 are rare.  The diagnosis is often first suspected
                 from the finding of stippled erythrocytes (SE)
                 in blood.  Although not diagnostic, SE should lead
                 to further investigations,  of which X-ray examina-
                 tion of the long bones is the most important.  The
                 possible value of EEC recordings  is discussed.
                 EEC's were performed in 2 of the  cases.  In dis-
                 cussing some of  the findings, the authors state
                 that glycosuria was observed in 2 cases, which as
                 suggested by Goettsch and Mason (1940) may be
                 pancreatic or  cerebral in origin associated with
                 hyperglyeemia, or renal associated with a normal  or
                 low blood sugar, with evidence pointing to the
                 latter.  Necropsy of the fatal case showed cause
                 of death to have been hemorrhage from acute ulcer-
                 ation of the esophagus.  The brain showed slight
                 cellular infiltration of pia arachnoid with peri-
                 vascular edema;  there was no evidence of encephali-
                 tis or vascular lesion.  Liver had undergone fatty
                 change with many hepatic cell nuclei showing
                 eosinophilic acid-fast inclusions.  In the kidney,
                 the most pronounced degenerative changes in the
                 cortex were acidophilic; acid-fast nuclear inclu-
                 sions were numerous.  Pb content in blood was
                 <0.03 Mg/100 ml; bone Pb, 89 ppm; liver, 53 ppm.
                 In the survivors, blood Pb  was determined in 3
                 cases:  blood, 0.3 Mg/100 ml (normal 0.01-0.03);
                 urine, 0.285 mg/24 hr (normal not >0.2).  Psycho-
                 logic reports  indicated considerable difficulty
                 with all items involving visual-motor coordination,
                 and low average intelligence.
                   Treatment should aim at immobilizing the Pb in
                 the bones.  "De-leading" should never be attempted
                 in children.
                   Pb poisoning in children could be entirely pre-
                 vented.  Pb paint should never be used in places
                 that children can reach.  Pb nipple-shields should
                 be prohibited.
                   The use of dimercaprol in  the  treatment of Pb
                 poisoning is discussed and is thought to be worthy
                 of trial, especially  in cases of Pb encephalopathy.

 The  answer  to  the query posed was  that  at present
 the  incidence  of Pb poisoning among  children  from
 their  gnawing  on baseboards, furniture  or toys is
 low.   At present few  coating materials  for  interi-
 ors  and furniture contain Pb, for  economic  rea-
 sons.   Lithopone and  titanium dioxide have  largely
 replaced Pb  compounds.  Some Pb may  appear  in the
 pigments, such as the greens and oranges.   No sub-
 stantial toy manufacturer now uses Pb paints.
 Synthetic dyes  have widely displaced mineral  pig-
 ments,  although traces of Pb may be  present in
 quick-drying agents.  No specific  federal laws
 have been enacted with respect to  Pb in these
 paints.  The matter chiefly has been solved on tne
 basis  of intelligent  understanding and  good faith
 on the part  of manufacturers.  Some  difficulty
 still  arises from the well meaning neighborhood
 friend of children who repaints old  toys, using
 whatever paint is on  hand.  Some of  the aniline
 dyes employed  on toys are  theoretically capable  of
 inducing methemoglobinemia, but the  quantity in-
 volved  is less  than in crayons.
occurs in the large majority of cases between 1
and 2-1/2 yr of age or during the "teething period."
Cases which are recognized before the onset of con-
vulsions are treated by the administration of fair-
ly large doses of Ca either in the form of lactate
or phosphate together with vitamin D to increase
the absorption of Ca.  Treatment of cases which
have convulsions as the result of a cerebral edema
is first directed toward decreasing the cerebral
edema by the sc injection of 10-20 ml of Mg sulfate
in 8% solution or 20-30 ml of 50% glucose iv.  Pb
poisoning is a preventable disease in children
and Pb-containing paints are the chief source of
poisoning.  In order to adequately prevent this
condition, the elimination of these paints from
the immediate environment of the child during the
2nd and 3rd yr of life is essential.  Pb-free
paints are readily available.  The principal haz-
ard occurs from repainted furniture in the poorer
class homes.  A fatal case of Pb poisoning was
found to have ingested <2/3 g of metallic Pb.
2857     Ross, J.R., and Brown, A. (Toronto, Can-
         ada) :  POISONINGS COMMON IN CHILDREN.
         Canadian Medical Association Journal 64:
         285-93, 1951.
The cases of poisoning admitted to the Hospital
for Sick Children, Toronto, over a 10-yr period
are presented.  Many drugs and chemical irritants
were responsible for the poisoning:  14% of the
cases resulted fatally.
  Poisonings due to Pb appeared to be more common
and also more fatal than any other single group.
In a summary made 4 yr ago, 23 cases of Pb poison-
ing were treated at the Toronto Hospital for Sick
Children during a 2-yr period.  Of these 23 cases,
10 had cerebral symptoms on admission and 5 of
these died.  One case resulted in cerebral sclero-
sis with mental retardation.  The remaining 13
cases were of latent Pb poisoning.  It usually
requires from 2-4 mo or longer of nibbling paint
before any acute symptoms arise.  During this per-
iod the child will become cross and there may be
complaints of abdominal pain.  Anorexia soon devel-
ops and this is usually associated with constipa-
tion and occasional vomiting.  The Pb symptoms
are characterized by the onset of convulsions.   In
the latent cases in addition to the finding of
stippled cells a dense white line may be seen at
the epiphyseal ends of the long bone on X-ray ex-
amination if the infant has been ingesting Pb for
a period of a month or more.  Confirmatory evi-
dence of this type of poisoning is the recovery of
Pb from the urine in a concentration >5 ug/100  ml.
A child who has a natural tendency to pica may
ingest sufficient Pb from many different sources
to cause symptoms.  Pb from repainted cots and
cribs, play pens, furniture, etc, may have a cumu-
lative effect in the body due to the fact that  it
is normally excreted very slowly.  The poisoning

          0.):  LEAD POISONING IN CHILDREN.  Cin-

There seemed to be a sudden increase in Pb poison-
ing in children in recent months.  Five diagnosed
cases in addition to suspicious cases were report-
ed to the Cincinnati Health Department since Jan-
uary 1, with 2 deaths reported this year and 1
additional death occurred that was suspected as
being due to Pb poisoning.  In 1950 3 children
died from this cause.  A study of the records for
the past 10 yr shows an average of 1 death/yr.
  There seems to be evidence that Pb is now being
used more frequently in paint, however, in most
cases it is the home repaint job that causes the
trouble.  It is generally known that children
chew painted surfaces, woodwork, window sills,
cribs, high chairs, other furniture, and toys.
In most instances children's furniture and toys
are finished with non-Pb paint when purchased.
  Pb poisoning is a definite health hazard in
young children and physicans should be alert to
its presence.  When discovered early, serious ill-
ness can be prevented.  The symptoms may be mild
for several weeks or months, consisting only of
headache, loss of appetite and anemia.  Other
symptoms may include pains in the abdomen, nausea,
vomiting, persistent constipation and convulsions.
  A recent study of 220 cases completed by the
Baltimore Health Department shows the following
age distribution:  <1 yr, 1; 1 yr, 37; 2 yr, 121;
3 yr, 32; 4 yr, 13; 5 yr, 8; 6 yr, 4; 7 yr, 2; 8
yr  and 10 yr, 1 each.  Of the 220 cases, 78 re-
sulted in deaths.

•Pb  poisoning  is still a pressing problem  in  the
 practice of pediatrics,  especially  among  young
 children living in  a poor  tenement  environment.
 Chewing  on furniture, toys  or woodwork painted with
 Pb-containing  paint is  the  chief source of this
 poison.   Some  of  the ingested Pb reaches  the cir-
 culation and  is then carried  to many  parts of the
 body.  Pb deposition in long  bones  gives  character-
 istic  lines.   In the brain, encephalitis  may en-
 sue.   The symptoms  are  at  first insidious.   Con-
 vulsions and  anemia with stippled red cells  are
 common.   Quantitative blood and urine studies
 help to  make  the diagnosis.   The prognosis is ser-
 ious,  since there is an appreciable mortality (20-
 30% in some series), and permanent  brain  damage
 is  frequent in those surviving.  The  treatment is
 not too  satisfactory.   Na  citrate has been used in
 recent years with some  success.  Supportive  therapy
 is  in  order,  chiefly anticonvulsive measures and
 blood  transfusions.  Recently EDTA  has been  in-
 troduced.  Further  evaluation is needed,  but it
 appears  promising.  A series  of 12  cases  observed
 in  the Hahnemann Hospital were reviewed.  The
 findings were  quite typical.  (17 references)

        MAKERS  IN PHILIPPINES CONTRACT LEAD POISON-
        ING.  Occupational Health 12:71 (May), 1952.
 It  is  reported  that several cases of Pb poisoning
 among  children  of storage battery makers have oc-
 curred in  the Philippines recently.  The families
 live in close proximity  to the workshop and the
 young  children  through ignorance or neglect of the
 parents are  allowed to play or eat near the place
 of  work and  were thereby exposed to Pb dust and
 fume.   Three cases of which 2 were fatal are de-
 scribed as an illustration of this occurrence.  A
 study  of Pb  poisoning among the workers in the man-
 ufacture, of  Pb  seals, bars, washers, and storage
 batteries  in Manilla showed high concentrations
 of  Pb  at the breathing level of the workers.  The
 physical,  urine, and blood examinations also showed
 chronic Pb poisoning, however no cases of acute.

 Pb poisoning from the ingestion of paint from wood-
 work in a 3-yr-old boy  was diagnosed on the  basis
                of  history,  X-ray  films  of  long  bones  and  the  pre-
                sence  of  Pb  in  blood  and urine.   On  the  9th  day  of
                hospitalization he was given  50  mg CaNa2EDTA iv,
                in  50  ml  of  5%  glucose solution.  This dose  was
                repeated  5 days later and for 2  additional doses
                at  8-hr intervals.  It was  then  doubled, and in-
                creased daily in 150  mg/day increments until the
                dosage on the 20th hospital day  was  750  mg/day in
                3 divided doses.  Therapy was discontinued after
                12  days because of marked improvement  in the pa-
                tient's condition. A total of 6.5 g CaNa2EDTA had
                been given.  None  of  the symptoms during the
                child's illness were  referable to EDTA.  A slight
                rise in the  blood  nonprotein  N suggests  that EDTA
                competes  with nitrogenous wastes for excretion.

                        (Oct.), 1952.
                Since 1931 the Baltimore City Health Department
                has recorded 350 cases of Pb poisoning in young
                children.   The ratio of cases and deaths between
                white and Negro children was 1:2; 107 cases and
                31 deaths among white children and 243 cases and
                60 deaths  among Negro children.  About 58% of the
                children (204)  were in the 12-24 mo age group
                (the teething age).  In 1951, when Pb poisoning
                was the 3rd ranking cause of death in the 1-4 yr
                age group in Baltimore, 77 cases were reported.
                Nine of the children died and 22 showed evidence
                of encephalitis.  Only pneumonia and tuberculosis
                killed more children in that age group that year.
                The Health Department's plan of attack has devel-
                oped along 2 lines:  (1) Home investigation and
                law enforcement; (2) education and publicity,
                stressing prevention.  For some years home visits
                have been made to all reported cases to find out
                the child's condition and also to ascertain the
                likely source of the material ingested.  The in-
                gestion of Pb pigment paint has been found to be
                the causative agent.  Under the Baltimore Ordi-
                nance on the Hygiene of Housing the presence of
                paint containing Pb pigment is interpreted as
                being a health hazard, and the elimination of the
                source of danger, when not done willingly, can be
                enforced.   In June 1951 the Health Department
                adopted a new regulation specifying that the
                painting of interior surfaces must be done with
                paint free of Pb pigment.   Pb poisoning is chiefly
                a  disease  of the slums  where bad housing conditions
                are prevalent.   In the  education and publicity cam-
                paign,  newspaper releases  and radio shows, pam-
                phlets,  and talks to interested community groups
                are employed.   Sanitarians,  assigned to housing
                and rodent control,  are particularly alert to the
                dangers  of flaking paint on their inspections and
                to the  need to have such conditions corrected.   Pb
                poisoning  in children has  been stressed in the edu-
                cational programs of the public health nursing
                staff and  affiliating student nurses.   The nurse

BIOLOGICAL ASPECTS OF LEAD

in a generalized public health nursing service
has excellent opportunities for casefinding and
preventive work in the area of Pb poisoning.  By
observing the condition of a child in a well baby
clinic or during a home visit and by inquiring in-
to a possible history 01 paint chewing or eating,
she can make a splendid contribution in cutting
down the incidence of Pb poisoning in young chil-
dren.  It is particularly important that a nurse
consider the possibility of Pb ingestion when a
child shows some of the more common symptoms of Pb
poisoning such as pallor, irritability, vomiting,
loss of appetite, and cramps, in addition to pica.
On visits to the home where there are small chil-
dren the public health nurse can well include the
prevention of Pb poisoning as part of her home
safety supervision.

Fourteen cases of chronic Pb intoxication are pre-
sented, 12 of which occurred from June-Sept. 1951.
In 10 of the 14 cases there was definite evidence
of encephalopathy.   In 2 cases tuberculosis men-
ingitis coexisted,  and the presence of Pb encepha-
lopathy could not be ascertained with certainty.
The signs and symptoms, diagnosis, treatment and
prognosis are tabulated and briefly discussed.

Three cases of chronic Pb intoxication were
presented which were treated with BAL in a
dose of 4 rag/kg body weight every 4 hr for 20
days.  Cessation of symptoms was noted in every
case.  Resting urinary Pb levels were increased
3- to 7-fold without exacerbation of symptoms.
BAL was found to be nontoxic in the dose used
and acted as an effective deleading agent.  The
authors feel that this form of treatment merits
use in both the chronic and acute phases of Pb
intoxication.  These 3 cases were part of the
group of 14 reported in the preceding abstract.

A 3-mo-old infant was hospitalized because of un-
usual listlessness, vomiting and convulsions,
culminating in coma after admission, apathy and
paleness having begun 1 mo before.  Findings in-
cluded severe normochromic anemia (Hb 40%), pro-
nounced increase in reticulocytes, 62/1000 stip-
pled erythrocytes, typical Pb lines in all long
bones upon X ray, increased CP in urine and uri-
nary Pb (while under BAL treatment) of 0.94 mg/1.
The EEC taken on the 1st day, before BAL was
started, showed severe pathologic signs, especial-
ly in the upper parietal region.  Although the
child improved under BAL therapy to the extent
that clinically no brain damage could be observed,
the EEC's taken 2, 4, and 12 wk after admission
were still pathologic.  1'he source of the poison-
ing was attributed to the mother's use of diachy-
lon salve (Pb oleate), prescribed by a physician
""6 wk before the child was admitted, for painful
sores on the nipples with instructions to use the
salve (15-25 g) only by alternating it with Zn
paste and to wash the breast carefully before
nursing.  The mother felt that the diachylon salve
was the better one, so she used it exclusively 4
times daily for at least 1 mo.  Before nursing
she washed the breast carefully with gasoline,
then soap and water.  The author concludes that
this had not prevented the absorption of Pb, with
the consequences described above.

The commonest cause of  Pb poisoning in children in
Britain is ingestion of paint on woodwork in the
home, particularly on cots.  The authors describe
5 cases of Pb poisoning (aged 3 yr or less), 4 of
which arose from the father's use of Pb paint for
renovating the cot.  These 5 cases bring the num-
ber of reports published in England during the
past 60 yr to 19, the source of Pb being:  painted
woodwork  (9), nipple shields (4), toy soldiers (2),
fumes from burning battery casings (2), drinking
water (1) and toilet powder (1).
  The 1st patient presented with, apart from other
signs and symptoms, diaphragmatic paralysis,
muscle pain and tenderness of the abdomen to pal-
pation, and bilateral foot drop 8 days after ad-
mission to the hospital.  Stippled erythrocytes led
to the diagnosis of Pb  poisoning, confirmed by
history of ingestion of Pb from the cot, raised
blood and urinary Pb, radiographic evidences of
Pb in the bones.  Recovery from polyneuritis, in-
cluding diaphragmatic paralysis, was complete after
3 wk.

  Radiographic appearances consistent with the
diagnosis of Pb poisoning were present in all 5
cases, with dense lines at the angles of the scap-
ulae  (2 cases).  Increase of stippled cells was
minimal in 1 case and absent in 2 cases.  Encepha-
lopathy was present without fits in 2 patients,
while another was admitted with convulsions, which
continued as status epilepticus for 24 hr despite
repeated im injections of paraldehyde.
  Treatment generally was by Ca lactate or glu-
conate, vitamin D, blood transfusions, milk or
high Ca diet.
  All 5 patients recovered.
  Pica, a common prelude to Pb poisoning, was ex-
hibited by all 5 patients.  Patient 2 (twin sister
of patient 1) had no history of illness but was
admitted owing to the family history, thereby
avoiding much delay in necessary treatment.  Many
similar cryptic cases of Pb poisoning probably
exist and it is emphasized that the paucity of
published reports does not reflect the potential
danger to children of paint containing Pb.  Serious
complications such as encephalopathy can be averted
only by early diagnosis and removal of source of
Pb, and by education of the general public to this
hazard.

As reviewed by the authors, chewing of paint from
cribs, toys, furniture, and window sills, and
eating of painted plaster and fallen paint flakes
cause  Pb poisoning in childhood.  Putting things
in the mouth, though normal in the 1st yr of life,
is abnormal, if continued much later and is re-
ferred to as pica, or perverted appetite.  Child-
ren of teething age living in old, run-down houses
where Pb paint has been used for years are especial-
ly likely to have Pb poisoning.  Although pica does
not exist on a seasonal basis, a striking number of
Pb poisoning cases resulting from this habit occur
in the hot summer months.   Though no explanation
for this phenomenon has been given yet, it has
been mentioned by several investigators.   Weeks or
months following repeated ingestion of small a-
mounts of Pb there may appear irritability, fret-
fulness or disturbed gastrointestinal function,
such as lack of appetite, constipation, vomiting
or cramps; there may also be pallor as the result
of secondary anemia.  More severe intoxication
results in Pb encephalitis, which may terminate in
death.  Central nervous system involvement or en-
cephalopathy rarely seen in adults with Pb poison-
ing, is common in children, whereas peripheral
neuritis, a Pb line on the gums, and colic are
usually absent in children.  A history of pica and
examination of blood smears for stippling of the
red blood cells are important aids in diagnosis.
Porphyrinuria is frequently found, and the demon-
stration by X ray of an increased density in the
growing ends of the long bones is a cardinal sign
of Pb poisoning.  The quantitative determination
of Pb in blood or urine is helpful in diagnosis.
  The authors review the efforts made in their De-
partment to diagnose and treat Pb poisoning in in-
                 fants.  Education of  the public  combined with  "Pb
                 consciousness"  in physicians  and pediatric  clinics
                 and with  a blood-Pb laboratory service  has  resulted
                 in a marked  increase  in case  recognition.   It  is
                 hoped  that education  and the  enforcement of mea-
                 sures  regulating the  use of Pb-containing paints
                 result  in a  material  reduction and  eventual elim-
                 ination of Pb poisoning in children.   (49 ref-

                 A 2-yr-old Negro girl was admitted  with  convulsions
                 that  developed after  anorexia and vomiting earlier
                 the same  day.  There was no history of head  injury,
                 exposure  to contagious diseases or  drug  ingestion.
                 Past  history revealed that the patient had fre-
                 quently put objects into her  mouth.  Laboratory
                 examinations upon  admission showed  the following
                 blood picture:  Hb, 2 g; erythrocytes, 2,700,000;
                 leukocytes, 10,000; lymphocytes,  38;  monocytes and
                 stippled  erythrocytes  (SE), 1 each.  X-ray studies
                 of the lower extremities revealed increased  densi-
                 ties  at the metaphyses of  the distal ends of both
                 femora and of the  distal and  proximal ends  of
                 both  tibiae and fibulae, which suggested Pb  poison-
                 ing.   This was confirmed by the finding  of SE and
                 the history of pica.  A  catheterized 12-hr urine
                 showed Pb excretions  consistent with a diagnosis
                 of Pb poisoning.   On  the 5th  day  in hospital the
                 patient became restless, lost appetite and seemed
                 apathetic.  Since  her condition worsened she was
                 given 1 g of CaNa2EDTA iv  in  50 ml  5% glucose
                 after 12-hr urine  rather than after 24-hr urine;
                 this  was  followed  90  min later by a severe general-
                 ized  convulsion which was  controlled by  2 grains of
                 Na luminal and oxygen inhalation.  Because respira-
                 tion  became  soon  shallow after  this the  respir-
                 ations were  stimulated by  electrophrenic respira-
                 tor  for 15 min.  Recurrence of  respiratory problems
                 necessitated  the  repeated  use of  the electrophrenic
                 respirator and  continued EDTA treatment  with satis-
                 factory results.   The authors were convinced that
                 the convulsions were  not due  to  the therapy, and
                 the continued  administration  of  the EDTA was justi-
                 fied  by the  course of the  patient.   The  data on

The correspondent was interested in the article in
the May 1952 issue of "Occupational Health," on
Pb poisoning among children of storage battery
makers.  He wished to know about the exact values
of the Pb content in urine in these cases and also
about any other investigations on the normal Pb
content in urine of children.
  He had seen some cases of children living in the
neighborhood of an electrochemical plant producing
dust containing some few percent of Pb compounds.
They showed a slight increase in the basophilic
values and excreted ^50 yg Pb, and several of them
showed a positive coproporphyrin test in urine.
They had no clinical symptoms but he felt the find-
ings indicated that they had been exposed to Pb.
As both the basophilic values and the coproporphy-
rin test are not very specific, he wished to know
more about urinary Pb values in children, before
starting further investigations.

A statistical survey is presented of 54 cases with
acute Pb encephalopathy admitted to the University
Hospital.  The patients, ranging in age between
15-84 mo (mean 29.4 mo) were divided into 2 groups
in order to evaluate the efficacy of BAL.  The 1st
group consisted of 38 cases which had occurred be-
tween 1931-48, ie, before BAL was used.  Of these
10 died (26.31%); this compares favorably with
McKhann and Vogt's finding of (1933) 25% mortality
and Holt's (1923) 65%.  The detailed complaints
and physical findings of this group are presented
in a table.  Group 2 consisted of 16 cases which
were treated from 1948-51 after the introduction
of BAL.  The mortality was 6.25% (1 patient).
  The authors present a brief analysis of the
clinical symptoms, signs, and laboratory data.
Stress is placed on the importance of supportive
measures in the management of acute Pb encephalo-

organic phosphate (1 qt of milk/day) and large
doses of vitamin D.  The diagnosis of Pb poisoning
was based on a history of pica, characteristic signs
and symptoms of Pb poisoning: basophilic stippling
of the red blood cells increased density at the
ends of the long bones, and an elevation of Pb in
the urine >0.08 mg/1.  When 1 or more of the fol-
lowing signs were present in a child with Pb poi-
soning, he was considered to have encephalopathy:
convulsions, increased intracranial pressure, per-
sistent vomiting, cranial nerve palsies, muscle
weakness or paralysis, ataxia, drowsiness, tremors,
and increased concentration of protein in the
spinal fluid.  Pb encephalopathy was considered
severe if the patient had repeated convulsions or
coma or stupor persisting for >14 hr.  Three of the
8 cases in the control group were severe and 5 mild.
In the BAL group 3 were severe and 3 mild.  BAL was
given in doses of 4 mg/kg of body weight every 4 hr
for 10 days.  In the noncomatose children treated
with BAL, signs and symptoms subsided in 24-36 hr.
The comatose children became alert in 24-72 hr, and
in 1 of the 3 recovery was complete within this
period.  The other 2 had ptosis of the eyelid,
which was transitory.  In the noncomatose child-
ren of the control group the presenting symptoms
persisted for from 3 days-1 wk.  Coma or stupor
lasted 3-5 days.   One child died after 3 days in
deep coma.  The other 2 comatose patients retained
severe neurological defects, hemiparesis, and blind-
ness.
  The authors conclude that BAL seems to lower
mortality and decrease the severity of residuals in
acute Pb encephalopathy.   In proper dosage  it
appears to be a safe therapeutic agent.

A fatal case of acute encephalopathy with meningeal
reaction in the spinal fluid and anemia due to Pb
poisoning in a 20-mo-old infant is reported.  For
5 mo prior to illness the child had been nibbling
at the window sills of the house in which she
lived.  The problem of differential diagnosis be-
tween Pb encephalopathy and tuberculous meningitis
is discussed.  On the basis of pathologic findings,
it is concluded that the principal morphologic ab-
normality in Pb encephalopathy appears to be an
alteration in the smaller blood vessels, which
produces an increase in permeability and multiple
zones of ischemic necrosis.  These are widespread
throughout the brain and the extensive damage ex-
plains why survival or normal mental function is
so rare.

levels were 0.147, 0.185, and 0.22 mg%.  Abnormal
electroencephalographic tracings were obtained
on all 3.   EDTA was administered iv in a 5%
glucose solution in daily doses of 1.0 g/30 Ib.
No more than 4.0 g/30 Ib/wk were given.  The high-
est dose given to any one patient was =14.5 g.
There were no deaths and clinical improvement of
variable degree was observed in all 3 patients.
  The authors conclude by stating that CaNa2EDTA
is highly effective in mobilizing Pb in vivo and
in rapid urinary Pb excretion.  (42 references)

Two fatal cases of Pb poisoning  in  children are
presented in which more careful  analysis of the
X rays of the chest might have resulted in an
earlier diagnosis.  A review of  10  additional cases
of Pb poisoning also revealed dense zones at the
anterior ends of the ribs on chest X rays.  These
observations emphasize the importance of careful
scrutiny of the anterior  ends of ribs on all roent-
genograms of the chests of infants  and children.

                 A,  B, and C were children 3-5  yr  old; D was  a
                 male adult.  A  and  D were started on EDTA in an
                 acute phase of  the  poisoning.   A  received 0.5 g
                 daily for 3 days beginning on  the 7th day, no
                 treatment for 4  days and 1.0 g/day for  2 days;
                 D received  0.5 g/day for 5 days,  none for 2, 0.5 g
                 for 4,  none for  2,  and 0.5 g the  last 2 days.  B
                 who had survived an acute episode was treated 2
                 wk later, and C, suffering from chronic poisoning
                 was treated 1 wk after exacerbation of  the symp-
                 toms due  to respiratory ailment.   The authors con-
                 clude  that  the  data reported indicate that admin-
                 istration of CaEDTA resulted in marked  enhancement
                 of Pb  excretion  in  these patients.

A  case  of cerebral palsy, although extremely rare,
is presented  in a 5-yr-old colored girl.  After an
initially normal development she developed pica,
causing an unsteady gait, irritability and a re-
gression in the toilet habits.  Three weeks pre-
vious to the  examination she suffered from pro-
jectile vomiting and became anorexic.  Laboratory
findings revealed the following:  Hb, 8.5 g; 3.64
million red cells; evidence of achromia, anisocy-
tosis,  polychromia and a few stippled cells;
urinalysis showed:  1.011 sg, acid, a trace of al-
bumin and a few white blood and epithelial cells,
Pb level 0.035 mg/700 ml (0.05 mg/1), sedimenta-
tion rate 8 mm/hr.  Numerous X-ray studies re-
vealed  Pb lines in the knees and wrists, on the
abdominal plate radiopaque material of metallic
density was seen in the rectum with Pb lines in the
iliac crest,  essentially a negative abdomen, the
chest plate showed generalized sclerosis of all
the visible bones and deep bands of increased den-
sity in scapulae and the sternal ends of the ribs.
Vitamin D and Ca lactate were administered to keep
the Pb  stored in the bones.
   After 17 mo, at follow-up examination she was
much improved and apart from some slow involuntary
rotary  motions in the feet and forearms and hands
there were no positive findings.  Diagnosis of
rotary  athetoid type of cerebral palsy was made.
Because of success in the treatment of post-enceph-
alitis  athedoids, artane was advised, but its ef-
fectiveness could not be judged in this case, since

                 with splenomegaly and achylia gastrica in a 7-yr-
                 old boy is described.  For 3 yr the patient had
                 repeatedly eaten Pb-paint, and for a long time he
                 had been suffering from malnutrition.
                   The difference between increased Pb-absorption
                 and Pb poisoning is discussed.  This patient
                 showed no symptoms of Pb poisoning.
                   The authors stress the fact that such paint also
                 contains other poisonous components which could
                 have caused the symptoms.  Finally the connection
                 between achylia gastrica and hypochromic anaemia
                 and the other causes of pica are discussed.

varied  in proportion with  the glycosuria.  As  the
level of the  amino  acids in  the plasma was normal,
this suggests that  the Pb  poisoning  caused a defect
in  the  renal  tubules.  Damage to  the kidney tubules
appears to be the immediate  cause of the  "acquired"
renal glucosuria and aminoaciduria in these cases.

A theoretical basis for the use of the Ca complex
of EDTA for the deleading of patients with acute
Pb poisoning is presented.  Of 7 cases of Pb en-
cephalopathy (4 boys and 3 girls 1-1/2-3 yr) treat-
ed with CaEDTA, 1 died soon after admission while
the others showed prompt clinical improvement.
Urinary excretion studies showed that ^1.8 mg Pb
is excreted/500 mg CaEDTA administered for maximum
efficiency of the therapy, ie, 0.5 g CaEDTA sc or
iv every 8 hr for 5 days, then a 3-day rest period,
followed by repetition of the course for 5 days.
No signs of toxicity from CaEDTA were noted.
  A general plan of therapy of Pb encephalopathy
with CaEDTA is presented.  The authors conclude in
stating that the likelihood of causing harm with
this therapy is minimal and the dangers that might
result from delay justify the course.  (16 ref-

        (Sept.), 1954.
EDTA is an organic chelating agent valuable in
treating Pb poisoning.  It is most active when
administered iv.  In the cases here reported it
was given to children orally.  Five were selected
with Pb poisoning contracted from eating paint or
plaster containing Pb.  In the hospital Pb excreted
in their urine was determined by the dithizone
method for several days before the EDTA was given
at 75 mg/kg weight/day in divided doses at 6-hr
intervals.  A significant increase in urinary Pb
promptly occurred in all the patients.  The maximum
excretion was reached between the 2nd and 4th days;
then the amount excreted dropped, but it remained
in excess of normal as long as EDTA was being
given.  EDTA was well tolerated and brought about
disappearance of anorexia and irritability.  A
number of observations were made during the period
on urinary coproporphyrin and on serum Ca and P.
The conclusion is that EDTA should be useful in
acute Pb intoxication and in Pb encephalopathy,
when the rapid elimination of Pb is required.  More
research is wanted as to iv administration and as
to dosage.  The value of EDTA is undoubted.

Five children with Pb poisoning whose case his-
tories are detailed were treated with EDTA.  The
diagnosis was based on identification of the source
of poisoning, on clinical symptoms, and on abnor-
mally high excretion of Pb in 24 hr.  Three at
least of 6 major signs had to be present to justify
the diagnosis; secondary anemia with basophilic
stippling; coproporphyrinuria; glycosuria in the
presence of normal blood sugar; X-ray evidence at
the metaphyses of the shafts of the long bones;
signs of involvement of the nervous system; and
vomiting, cramps and constipation.  In 4 cases the
Pb excretion was >80 pg/24 hr.  When EDTA was given
an increase in Pb output in the urine occurred,
varying between 10-fold and 40-fold with rapid
improvement in symptoms.  One patient admitted in
coma and convulsions was sitting up and feeding
herself 36 hr later and began to talk in 48 hr.
None of the others was so severely ill, but all
were free of abdominal complaints promptly.  Co-
proporphyrinuria disappeared in 7-10 days.  The
dosage of EDTA was 1 g/15 kg body weight/day, in
2 doses, administered iv in 250 ml of 5% dextrose
solution.  Not more than 5 g/15 kg body weight was
given in any 1 wk.  As the children tend to return
to their habit of paint chewing, they must be re-
moved from any possible temptation.  Observations
indicated that the occurrence of any infection will
cause Pb to be transported from the bones to the
soft tissues and so precipitate signs of Pb poison-
ing; in such a case EDTA is indicated immediately.
EDTA appears to  be a safe agent for removing Pb
from the body.

Various analytical methods based on the striking
color produced by the reaction between Pb and
diphenylthiocarbazone (dithizone) were explored by
the authors.  Methods based both on titration and
direct colorimetry were studied, but though they
gave quantitative data on aqueous solutions of mix-
ture of salts, with urine the results were too un-

vestigation  the authors found that by employing a
modification of Fairhall's micromethod, which uses
dithizone for  the preliminary separation of Pb but
that  extracts  the Pb from the dithizone and analy-
zes it as the  dichromate, accurate estimation of
the 24-hr urinary Pb was possible in properly col-
lected samples.
  Urinary excretion of Pb was studied in 68 child-
ren between  the ages of 6 mo and 14 yr.   Most of
the children studied were controls,  who had no
history of exposure to Pb, but diagnoses of Pb poi-
soning were made in 23, and aside from any help ob-
tained by measurement of urinary Pb excretion, the
diagnoses were based on the presence of at least 3
of the major clinical signs of Pb poisoning in
children; (1)  secondary anemia with stippling,
(2)  evidence of involvement of the central or
peripheral nervous system or both, as exemplified
by clinical  symptoms and signs and/or spinal fluid
changes,  (3)  X-ray evidence of condensation of the
lines of  the provisional calcification of the
shafts of the long bones, (4)  glycosuria with nor-
mal blood sugar, (5)  abdominal complaints, ie,
vomiting, cramps, and constipation,  and (6)  chem-
ical identification of the source of Pb.  The ex-
cretion of >80 yg Pb/24 hr always indicated Pb
poisoning in the age group examined.  Values from
55-80 yg/24 hr always indicated more than the usual
contact with Pb and the possibility of Pb poisoning.
Values <55 yg/24 hr occurred in desperately ill
patients with Pb poisoning, when renal blood flow
was believed to be inadequate and for no apparent
reason in 1  child with Pb poisoning.  All control
patients gave values <55 yg/24 hr.  After a yr or
more of protection from Pb ingestion, the urinary
excretion of Pb in patients with known intoxica-
tion fell into the normal range.
  The finding of a normal urinary 24-hr Pb excre-
tion appeared to be fairly reliable in excluding
recent Pb poisoning in persons with adequate renal
blood flow.  The authors illustrated on the basis
of a case history the mistake of diagnosing Pb poi-
soning on the basis of a history of pica for paint
and characteristic X-ray evidence in the bones.
Urinary excretion of Pb was 21 and 14 yg/24 hr on
2 successive days, and samples of paint from the
chewed window sills showed no Pb.

Basophilic granulated blood corpuscles, copropor-
phyrinuria, X-ray density of the metaphyses  and a
pathological EEC suggested the possibility of Pb
poisoning in a 10-mo-old child with convulsions.
However, absence of exposure during the previous
40 days before the appearance of symptoms as well
as the absence of Pb in the urine render the diag-
nosis of Pb poisoning questionable.  The patholog-
ical findings rapidly became normal.

                 A follow-up was made of 401 children, who were in
                 the Hospital for Sick Children, Brisbane, between
                 the years 1915 and 1935 with a diagnosis of Pb poi-
                 soning.  Of these, 165 are known to be dead and
                 187 to be alive, and nothing is known of the fate
                 of the remaining 49.  One hundred eight of the
                 causes given on the death certificates were classi-
                 fied as being renal or vascular disease.  Seventeen
                 of the living members have hypertension and albu-
                 minuria and 3 have hypertension alone.  The evi-
                 dence available indicates that the original diag-
                 nosis of Pb poisoning was probably correct in the
                 majority of the cases.  (14 references)

                 The author describes briefly the results of re-
                 search on Queensland chronic nephritis, stating
                 that evidence shows the high incidence of the dis-
                 ease to be due to Pb absorption in childhood.  In
                 comparison with the remainder of Australia, mor-
                 tality from chronic nephritis in Queensland began
                 to rise about 1890 with the rise affecting the 10-
                 20 age group first, then the older ones in suc-
                 cession, reaching the 50-60 age group about 1930
                 but not extending to the groups >60 yr of age.
                 The incidence in the younger age groups began to
                 diminish about 1925 when the causative agent, ap-
                 pearing in 1890, began to disappear about 1920-30.
                 Follow-up of persons who as children had had Pb
                 poisoning between 1915 and 1935 showed that at
                 least 128 of the 400, and probably more, have
                 died of it or are still living with "chronic neph-
                 ritis."  However, only a relatively small percent-
                 age (10-20) of such cases state a history of Pb
                 poisoning in childhood.  This may mean that either
                 Pb poisoning is only partially responsible or Pb
                 absorption in childhood occurred without any clin-
                 ical  manifestations at the time.  In order to
                 maintain the thesis that excessive Pb absorption in
                 childhood is the major cause of the high mortality
                 from chronic nephritis, some evidence must exist
                 that excessive Pb was absorbed in the majority of
                 cases, done by estimations of bone-Pb content at
                 autopsy.  Although studies at this time were as
                 yet incomplete, they showed a bone Pb content signi-
                 ficantly higher in the majority of cases of "chronic
                 nephritis" including those with  no known past
                 history of Pb absorption than in controls.  The
                 mechanism by which Pb produces the renal lesion
                 remains unknown and work on experimental animals
                 has until then proved fruitless.  The author closes
                 his report by a statement of studies as yet to be
                 done and the announcement of a forthcoming paper
                 on the statistical and clinical aspects of Queens-
                 land nephritis, pending bone-Pb estimations in an
                 adequate number of autopsies.  (20 references)

BIOLOGICAL ASPECTS OF LEAD

-------
        108 (Jan.-Feb.), 1954.
The symptoms, diagnosis, prognosis and treatment
of Pb poisoning with encephalopathy in children
is first reviewed.  The case reported was that of
a 4-1/2-yr-old white boy who was admitted to the
hospital with convulsions.  As summarized by the
authors, this was a typical case of Pb encephali-
tis, presenting gingival line, anemia, reticulo-
cytosis, stippled cells, radiologic changes and
Pb content of blood 72 ug/100 ml.  In addition
to classical treatment vith Ca citrate, oral and
injected Ca, vitamin D, and phenobarbital, BAL was
administered.  At discharge, psychiatric examina-
tion showed mental retardation.  The source of
Pb exposure was the father's home shop of repair-
ing and constructing storage batteries, where the
child played and chewed Pb scraps.

        Cincinnati, 0.):  LEAD POISONING IN CHIL-
        DREN.  1.  MEDICAL CARE.  2,  NURSING CARE.
        American Journal of Nursing 54:736-8;
        738-9, 1954.
In Part 1, Smith emphasizes that because Pb poi-
soning in children is frequently not suspected
until brain damage has resulted, general awareness
and an informed population along with doctors who
are alert to the early manifestations is called
for.  Based on his experience in Cincinnati the
incidence is increasing rather than decreasing.
Over the period 1944-1954 out of 40 reported cases
in Cincinnati 15 were fatal and the surviving 25
children exhibited some degree of encephalopathy;
of the latter, there are probably 3 idiots.  A study
by Byers and Lord (1943) suggests that even in
milder cases an unhappy outcome may result.   They
reported their observations on 20 cases of Pb poi-
soning without gross brain damage at discharge from
hospital;  8 children had exhibited mild encepha-
litic symptoms but 12 showed no such involvement.
Only 1 of the 20 had consequently been able to make
a normal school adjustment.
  As the early manifestations are given: abdominal
pain, frequent anorexia, vomiting,  persistent con-
stipation, irritability, frequent headache,  pallor,
anemia and pica.  More serious symptoms show as the
intoxication advances.  The Pb-gumline is not com-
mon with children.  Blood smears to determine the
stippled erythrocytes, lumbar puncture, examination
of the long bones, urinary coproporphyrin tests and
analysis of the whole blood are the recommended
diagnostic aids.  Since no specific drug can be
recommended by the author, he feels that skillful
nursing aid has to be relied on to bring some com-
fort and relief for the sick children.
  Houston outlines the nursing care during intra-
venous therapy and presents instructions for nurses
in presurgical therapy and postoperative care.  At-
tention is drawn to the role of parents as part of
the team that takes care of the child that is hos-
pitalized for Pb intoxication.

A fatal case of Pb poisoning  in a 23-mo-old  child
with a history of eating paint is reported.   Since
the neuropathologic findings  observed  in  this case
seemed more consistent with a pathogenesis  of
bacterial toxins derived from a septicemia  than
with an exogenous toxin, Pb,  tl,e  theory was  ad-
vanced that abnormal concentrations of Pb in the
blood inactivate antibodies diminishing resistance
to bacterial invasion and growth.   Pb at a concen-
tration of 0.12 mg/100 ml precipitated Y~globulins.
Therefore, it is postulated that  this action  can
also affect the antibody systems  since these  are
y-globulins.  Through this inactivatlon of the
antibodies,  the pathological  changes in the central
nervous system may be the result  of the toxic
products of the less inhibited growth of infectious
agents.  In those instances where the blood Pb
level exceeds the critical range,  the elapsed time
may not have been sufficient  for  the manifestation
of the direct toxic effects of the Pb.

In the United States  in 1949-1950 the annual num-
ber  of deaths due to  accidental poisoning in chil-
dren <5 yr  of age was 2.6/100,000 population,  or
4 times that of  Great Britain.  This fact indi-
cates a carelessness  or complacency that cannot
be condoned.  Add to  this the fact that for each
child who dies from this cause many recover and
that many of these are  left crippled by Pb  encepha-
litis, liver or  kidney  damage,  and cicatricial
closure of  the esophagus, and the magnitude of
the  problem, far exceeding  that of poliomyelitis,
becomes apparent.  Poisonings by chewing Pb paint
or by Pb fumes resulting from the burning of old
battery casings  are among those mentioned.  Steps
taken to prevent these  accidents are discussed.

suit of a disturbance of renal tubular function
due to Pb.  This disturbance was reversible and
disappeared under treatment.  The similarity of
this biochemical disturbance to that observed in
the Toni-Fanconi syndrome is pointed out.  The
authors suggest that the same or related renal
tubular enzyme systems are involved in Pb poison-
ing.  Citrate accelerated the healing of rickets
in the presence of a toxic concentration of Pb
which had produced the defect of calcification
initially.  As calcification of new bone occurred,
Pb was deposited with the new bone salts.  With
the removal of Pb to a tissue where it was de-
posited in a physiologically inert form, the inter-
nal balance of Pb metabolism was shifted and soft-
tissue concentrations of Pb were reduced; coinci-
dentally biochemical renal tubular dysfunction
disappeared.  (24 references)

         8, 1955.
In an editorial on the incidence of Pb poisoning
in childhood, its diagnosis and treatment, atten-
tion is drawn to the fact that correct diagnosis
depends largely on considering Pb poisoning a pos-
sibility when several cases occur within a short
time among children.  Confirmation or exclusion
of the occurrence of a dangerous degree of Pb ab-
sorption may be accomplished by the determination
of the Pb concentration in whole blood.  Sometimes
the confirmation, not the exclusion,  can be
achieved by the analysis of urine, but in children
the analysis of whole blood is to be  preferred.
CaNa-jEDTA is recommended to remove Pb from the
system and preferred over BAL or cortisone or cor-
ticotropin.

        MENTAL DEVELOPMENT INDUCED BY LEAD-POISON-
        ING.  British Medical Journal 1:320-3
        (Feb. 5), 1955.
A case of arrested mental development in a 7-1/2-
yr-old boy caused by Pb poisoning (probably at age
3) was described and its implications and those of
others in the literature discussed with particular
reference to the following:  (1)  The diagnosis of
Pb intoxication may be delayed over long periods
during which serious and possibly irreversible
brain damage may be done, with resultant arrest of
mental growth, the appearance of "sensorimotor"
defects, and both social and educational disabili-
ties.  (2)  Pica, more often than not, precedes Pb
poisoning in children, and, as its implications
are not always recognized, its occurrence may not
be reported with appropriate emphasis.  Hence there
is the possibility that Pb ingestion is not con-
sidered when the presenting symptomatology suggests
such conditions as food poisoning, pertussis, in-
fantile autism, amentia, sensorimotor defects,
educational subnormality, hyperkinetic disease, and
behavior  disorders.  (3)  The need for appropriate
screening and follow-up procedures has been indi-
cated in the light of probability that the real
incidence of Pb intoxication is much greater than
hitherto envisaged.
                   The authors hope that the Ministry of Health,
                 local authorities, medical practitioners, parents,
                 and all concerned with child welfare will take
                 appropriate action to safeguard children from ex-
                 posure to the risks of Pb poisoning.

                 Previous  reports  on the use  of EDTA  in  the treat-
                 ment of Pb poisoning  have  all come from US.   EDTA,
                 or  CaNa2   versenate,  is the  Ca complex  of ethylene-
                 diamine tetraacetic acid,  which is a chelating
                 agent, ie, a  substance capable of binding multi-
                 valent metallic ions  so as to cause  their function-
                 al  removal from a solution.  A metal forming  a
                 stronger  complex  can  replace one forming a weaker
                 complex.   Thus, Pb replaces  Ca from  the CaNa2 com-
                 plex, which,  for  this reason, is used in the  treat-
                 ment of Pb poisoning.
                   The patient  treated was  a  child, 2-1/2 yr old,
                 who became ill after  chewing Pb-coated  telephone
                 wires.  In addition to ordinary signs of Pb poison-
                 ing, X rays of the long bones showed dense bands at
                 the metaphyses.   Symptoms  of encephalopathy were
                 developing when treatment  was started.  EDTA  was
                 given iv  at intervals of 12  hr at  0.5 g in 200 ml
                 of  0.18%  NaCl  in  4.3% dextrose.  Each infusion
                 lasted ^2 hr.  Three  5-day courses were given,
                 with intervening  rest periods of 6 and  9 days.
                 The mental condition  improved steadily  and the
                 child was bright  and  alert in 3 days.   Vomiting
                 and convulsions ceased.  Corproporphyrin gradually
                 disappeared from  the  urine,  as well  as  stippled
                 cells from the blood.  The blood Pb  level steadily
                 fell, and there was an increase of excretion  of Pb
                 in  the urine, but this was not increased further by
                 ammonium  chloride.  No toxic effects from EDTA were
                 noted.  (15 references)

                  diagnosis  of  Pb  encephalopathy which the  general
                  practitioner  had made.   Immediate action  was taken:
                  the house  of  the children was visited, but  it was
                  the area Health  Visitor  who provided the  informa-
                  tion that  it  was a fairly common practice to burn
                  old battery casings as fuel.   A detailed  account
                  is given of the  well-planned  and extensive  inves-
                  tigations  which  were  then made to discover  the
                  homes  where battery casings had been burned, to
                  have these homes visited to secure information and
                  to examine clinically and pathologically  as many
                  of the children  and adults  as possible who  had
                  been at risk.  Details of the analysis of the cas-

                  were that  no  case of  Pb  poisoning in adults was

 sonlng and 49 cases of Pb absorption in children
 were  observed.   In addition,  the bodies of  2 dead
 chidren were exhumed and analysis of the organs
 indicated that death had been due to the inhalation
 of Pb.  The causes of death in these had been said
 to be epilepsy in one and cholemia and infectious
 hepatitis in the other.  There appeared to  be
 little doubt that the source  of the Pb was  either
 the unburnt Pb casings or the ash after combustion,t
 but the route of the Pb into  the system must
 remain uncertain.  The protection of the public
 from  the danger  of Pb poisoning through battery
 casings is discussed.

The case is reported of a 20-mo-old male infant
hospitalized with signs of Pb intoxication proba-
bly due to chewing dry paint from window sills.
Symptoms also indicated encephalopathy, although
an EEC taken during sleep was normal.  After un-
successful symptomatic treatment, the patient vas
treated with EDTA administered in a dose of 0.5 g
of EDTA/100 ml physiologic saline by subcutaneous
clysis.  The clyses, administered 3 times/day for
5 days, were given over a 1-hr period; absorption
occurred between 1-1/2-2 hr.  The procedure was
well tolerated.  The course of the case is des-
cribed; on the 5th day of therapy considerable im-
provement was obvious; and the patient was finally
discharged, cured.  A year later he was seen in
excellent health.  The theoretical value of EDTA is
discussed.  The claim is made that EDTA is the drug
of choice in Pb poisoning; it is effective and can
be easily administered by the method described.

Cases of Pb poisoning in children, with fatalities,
have occurred in St. Louis.   The ingestion of ma-
terial containing Pb compounds is the cause.  The
incidence of Pb poisoning in children in St. Louis
is highest in the summer season, when the total
actual sunshine hours are the greatest.  The prob-
lem of pica is inextricably nixed with the cases
of childhood plumbisai.  A discussion on the le^al
steps to be taken and stress, placed upon early
diagnosis and adequate treatment, conclude the
paper.  (From authors' summary)

        CLINICAL AND PATHOLOGICAL FINDINGS.  Brit-
        ish Medical Journal 1:324-6 (Feb.  5),
        1955.
A description of the clinical and pathologic find-
ings of 2 fatal cases of Pb poisoning in children
 is  presented.   Particular  attention  is  given to
 the changes  in the  kidneys,  since  these changes
 have very  often been underestimated  in  previous
 literature.  The difficulty  in making a diagnosis
 of  Pb poisoning is  emphasized.   The  author  cites
 Anderson (1948)  who pointed  out  that the central
 nervous  system is particularly susceptible  at
 early age, and that encephalopathy may  develop
 even in  the  absence of  anemia  and  colic,  which
 points to  the  need  of considering  Pb poisoning in
 the presence of vague cerebral symptoms or  evi-
 dence of increased  intracranial  tension.
  In both .cases described, vague symptoms were
 present  toward the  end  of  the  2nd yr, but no
 diagnosis  was  made  at that time.  Case  1 lived to
 the age  of 4 yr when the anemia, constipation, ab-
 dominal  colic  and basophilic stippling  suggested
 Pb  poisoning;  in the 2nd case  the diagnosis  was
 made at  necropsy.   In discussing the gross and
 microscopic  findings, the  authors state that these
 were not striking.   There was  some increase  in
 weight of  liver and kidneys, and giant  nuclei in
 the renal  tubules.   Damage to  the cortex and outer
 portion  of the medulla  involving convoluted  and
 looped tubules was  seen, but no  evidence  of  cellu-
 lar infiltration.   The  pattern of the urine  chro-
 matogram confirmed  Fanconi's theory  on  the absorp-
 tion of  dextrose and amino acids in  the proximal
 tubules.
  The author notes  that postmortem diagnosis is
 facilitated  by examining the cut end of a rib for
 the white band close to the  cartilage,  and by ex-
 amining  frozen sections of liver and kidney  for

During  1953,  21 cases of Pb poisoning in  children
were detected, 5 of which were fatal.  The child-
ren ranged in age from 10-44 mo and pica was the
outstanding precursor.   Vomiting, constipation,
abdominal pain,  weight loss, lethargy, irritabil-
ity and convulsions were the principal signs and
symptoms and appeared mostly during the summer
months.   A behavioral syndrome characterized by
irritability,  tearfulness,  weakness,  withdrawal
and unexplained crying commonly occurred 1-2 wk
prior to hospitalization.  The diagnosis was con-
firmed by the detection of  anemia, basophilic
stippling of the erythrocytes,  increased copropor-
phyrinuria, elevated urinary and blood Pb levels
and traverse bands of increased density at termin-
al segments of the growing  bones on X ray.  There
was no pattern in the geography of the incidence
although the cases were largely confined to the
slum areas.
  The 5 fatal cases died of  encephalopathy.  Of
the surviving 16 children,  15 were studied 4-6 mo
after discharge from hospital by using detailed
developmental histories and  tests, observing spon-
taneous and elicited behavior and interviewing the
parents.  Prior  to the onset of Pb poisoning,  only
1 of the patients was retarded in motor develop-
ment, 3 were slow in speech  development and 6 were

emotionally immature.  Approximately 6 mo subse-
quent to the poisoning 14 of the 15 patients were
found to be markedly retarded in some way:  lan-
guage ability (12),  finer muscle coordination (11);
10 children became emotionally unstable and ex-
treme distractibility, short attention span and
high variability on the psychological tests were
characteristic.  (From authors' summary)

Two cases are reported, stated by the author to be
typical of Pb poisoning in children <3 yr old:
Case 1 was a 30-mo-old girl who had eaten paint
from window sills for 4 mo; Case 2, 22-mo old,  had
done so for 5 mo.   In the 1st,  screaming  had de-
veloped suddenly,  then vomiting; at admission,
hemoglobin was 7 g/100 ml, X rays showed increased
density at ends of the radius and ulna, increased
excretion of coproporphyrin (CP), 0.1 mg Pb/1
urine, and 133 yg Pb/100 ml blood were found; EEC
revealed some slowing of the waves.  In the 2nd,
vomiting and clonic convulsions had occurred; she
showed signs of palsy of the 6th cranial nerve,
EEC indicated extensive slowing of waves; other
findings were similar to Case 1  (urinary Pb was
0.09 mg/1, olood contained 83 yg/100 ml).  The
1st child was treated with Na citrate, high Ca
and vitamin D diet, and Case 2, with BAL.  The au-
thor discusses the diagnosis, stressing the impor-
tance of CP determination, and treatment with che-
lating agents.

        of Diseases of Children 89:325-31, 1955.
A report is presented on 33 cases of Pb poisoning
in children 10 mo-4-1/2 yr old.   Of the cases 43%
was in the age range 1-2 yr, and 27% from 2-3 yr,
20 of which were diagnosed from 1939-52 and 13 in
1953.  In the latter group, diagnosis was substan-
tiated by history and laboratory examination.
The 20 boys and 13 girls were from the lower so-
cioeconomic classes from all over Chicago.  Most
cases occurred in June-August (79%).   Six cases
were fatal (18%).  The frequency of symptomatic
complaints is tabulated.  Among  the findings hy-
pochromic anemia was found in 14 children; baso-
philic stippling in 94%; abnormally high reticulo-
cyte count in almost all; in ^50%, albumin was
found in the urine, and in 21%,  glucose.  The uri-
nary Pb excretion was significantly elevated in
20 although there was no correlation between the
degree of severity of the symptoms and the quan-
tity of Pb excreted/24 hr.
  Of 8 children whose urine was  analyzed for por-
phyrin 6 exhibited increases; however, porphyrins
were not present consistently in the urine.
Blood Pb levels were analyzed in only 2 patients
before 1953  (results, 0.067 and 0.167 mg/100 ml vs
normal of 0.03-0.06 mg/100 ml).   The author noted
that because of the apparent increase in Pb  poi-
soning in 1953, this disease will probably become
                 reportable in Chicago.   Facilities were made
                 available for blood Pb  determinations.   Four sam-
                 ples so analyzed showed 0.047-0.109 mg/100 g.   It
                 was thus seen that the  value of blood determina-
                 tion (under consideration of variables  such as
                 time of day of sampling, ingestion of food and pH
                 of the blood) lies in its use in screening pa-
                 cients with possible Pb intoxication.  Aside from
                 the above findings, signs of increased  intracra-
                 nial pressure (papilledema, Macewen's cracked-pot
                 resonance) were present in the children who died.
                 Tremor, ataxia, and motor weakness were seen in
                 several others.  Bone X-ray changes were signifi-
                 cant in 85% of the patients, and 3 children
                 showed in addition increased density throughout
                 the large intestine, indicating recent  ingestion
                 of Pb paint chips.  Abnormal constituents in the
                 cerebrospinal fluid, in the absence of papillede-
                 ma, were found in 20 of the 33 cases.  Electro-
                 encephalograms were taken during the course of
                 acute illness in 8 patients, and in 4,  after dis-
                 charge.  In 6 of the 9 cases treated with CaNa2~
                 £.DTA iv, excellent results were obtained, with no
                 adverse effects; in only 1 case was a direct sen-
                 sitivity to the drug suspected.  The blood and
                 spinal fluid chemistries and urinary Pb findings
                 before and after treatment are tabulated.

                 During the period 1940-1950, 26 children were
                 treated for Pb intoxication.  The source of Pb was
                 ingestion (paint, plaster, toys).  Of them 7 (27%)
                 died:  6 on initial hospitalization and one 2 yr
                 later with Pb encephalitis.  Of the remaining 19
                 patients 11 were followed for a 5-10 yr-period with
                 repeat physical, psychologic and laboratory examina-
                 tions.  Five of them had been diagnosed and treat-
                 ed on an outpatient basis and the other 6 were
                 hospitalized.  Of the latter, 2 were subsequently
                 hospitalized with intercurrent infections which
                 precipitated a return of the symptoms of Pb intox-
                 ication.  The patients were empirically classified
                 as mild, moderate, moderately severe, and severe.
                   As summarized, the physical sequelae consisted
                 of blindness and cerebral dysrhythmia.  Na citrate
                 was the specific therapy in all cases and was
                 given over a variable period of time or until there
                 was no laboratory evidence of Pb intoxication.
                 There was no evidence in this series of continuing
                 mental deterioration.  Considering the major mode
                 of instruction in the primary grades, the authors
                 feel that these children are at a serious disad-
                 vantage and should receive special attention to
                 offset their visual-motor deficit.  As the child
                 matures there is a gradual loss of the inward
                 driven hyperactive behavior frequently seen in
                 brain-damaged children.  There is no direct cor-
                 relation between the severity of the illness and
                 the amount of residual effect.  Pediatric counsel-
                 ing might be influential in reducing a parental
                 overprotective attitude which adds to the child's
                 problem.  (20 references)

A 23-mo-old child who had ingested a key-chain em-
blem made of a Pb containing solder alloy and re-
tained it in the stomach developed anorexia, vomit-
ing, weight loss, and irritability after ^45 days.
After surgical removal of the emblem on the 68th
day, Pb intoxication was proved by Pb lines in
X-ray pictures of the long bones and by profuse
basophilic stippling of red blood cells.  It was
successfully treated by CaNa2EDTA.  After the 1st
course of treatment, the 24-hr urine contained
0.056 mg Pb and the serum contained 0.01 mg Pb/
100 ml, and after the 2nd, <0.01 mg/100 ml.

Attention is being focused on the  relatively high
incidence of Pb  intoxication in children due fre-
quently to the pica habit.  In the period 1931-
55,  462 children, most of whom came  from low-in-
come areas of Baltimore, were admitted to hospi-
tals with Pb encephalopathy or other manifesta-
tions of Pb intoxication.  In many cases the chil-
dren had opportunity to eat or chew  flakes of
paint from the ill-kept houses.   This large num-
ber  of cases suggested that there  might be a high
incidence of Pb  intoxication in the  same areas in
children who did not show significant or recog-
nized symptoms of Pb poisoning.   An  investigation
was undertaken of 604  children of  ages 7-60 mo,
all of whom came  from a low—income area and attend-
ed a Well-Baby Clinic at the University of Mary-
land Hospital.   Urine was examined for copropor-
phyrin (CP) III  (de Langen and ten Berg modified
by McCord).  This gave opportunity to assess the
value of the  test since it is used by many indus-
trial firms as a method of screening their workers
for exposure to  dangerous amounts  of Pb.  All
children with a positive CP test of 2+ (197 chil-
dren) and alternate children with  a negative CP
test had the following additional  studies:  blood
Pb determination  (dithizone method), lib, erythro-
cyte count, stipple count, X ray of  long bones,   a
complete history  and a careful physical examina-
tion.  The results are described,  shown in tables
and discussed.  As summarized, the findings were:
(1) The mean blood Pb for the 2  groups was 0.043
mg%; the upper limit of normal blood Pb seems to
be 0.05 mg%,  as at and above this value there was
an increase in symptons and findings ascribed to
Pb intoxication;   (2) there was no significant dif-
ference of blood Pb or other findings of Pb intox-
ications in the patients with or without CP; (3)
abnormal blood Pb values were found in 44.4% of
the 333 children studied; and (') a history of
pica was noted in 69.6% of the children with a
blood Pb of SO.05 mg%.   This one finding gave high-
er correlation with blood Pb than any other test
or symptom.  (17 references)

        INTOXICATION.  Journal of Clinical In-
        vestigation 35:1131-8, 1956.
In children with Pb poisoning a positive correla-
tion was demonstrated between the urine Pb output
during the 1st day following the parenteral admin-
istration of EDTA and the total daily urinary co-
proporphyrin (CP) output just prior to the admin-
istration.  This relationship is an exponential
one and was demonstrated in both the early re-
covery phase and the chronic phase of Pb poison-
ing.  A similar correlation was found between the
simultaneous daily urinary excretion of CP and Pb
during EDTA administration.  During the convales-
cent phase in children who had recovered from
acute Pb encephalopathy an exponential relation
was also found between the whole blood Pb concen-
tration and total daily urinary CP excretion.  This
relationship could not be shown during the initial
acute phase of encephalopathy when whole blood Pb
concentration was frequently quite high and de-
creasing rapidly.  These data indicate that the
urinary CP output is related to that fraction of
Pb in the tissues which is available for chelation
and urinary excretion under the influence of EDTA.
From the urinary CP output one can predict the
magnitude of Pb output in the urine which will
follow the parenteral administration of EDTA.
Since it is believed that this chelating agent
initially removes Pb primarily from nonskeletal
tissues, it appears reasonable to propose that the
urinary CP output is correlated with the concen-
tration of Pb in soft tissues.  Hence, the urinary
CP excretion provides a sensitive biochemical
index of "metabolically active" and presumably
toxic Pb in tissues.  (From authors' summary; 24

Ingestion of paint chips and  plaster containing
Pb  is  an  important cause of plumbism in children.
Indentification and removal of environmental
sources of Pb  is essential, since  constant super-
vision of children to prevent eating of Pb-contain-
ing materials  is impractical  when  these materials
are within the child's reach.  The old  Pb-contain-
ing paint should be burned away completely or the
child  should be transferred to a dwelling in good
repair.   Among children who survive acute Pb en-
cephalopathy,  frequency of permanent central ner-
vous system dariage Is increased b? reexposure to
Pb.

  In old, poorly maintained dwellings, layers of
flaking paint often contain excessive quantities
of Pb.  Even if Pb composes only 1% or less of
total solids in each layer of paint, application
of several layers to one surface increases the
quantity of Pb per unit area to tlv-j extent that
even a small flake may contain toxic concentra-
tions.  In 1 home, paint flakes weighing 2.68 g
which were renoved from a door frame contained
254 mg of Pb.  Because intake of more than 1.5 mg
of Pb daily may cnuse toxic symptoms, ingestion
of even a small quantity of such paint is danger-
ous.
  Symptomatic Pb intoxication is tnost frequently
observed in the summer.  Possibly, vitamin D and
the actinic rays of the summer sun increase the
absorption of Pb from the intestine.  Heat may
lead to dehydration and acidosis in small children
and thereby promote encephalopatny.
  The mean daily fecal output of Pb among 6 chil-
dren with Pb poisoning was ^6 times fecal Pb out-
put in a group of severely exposed industrial work-
ers.  The more frequent occurrence of encephalop-
athy in children than in adults probably depends,
therefore, upon mor?. intense exposure to Pb in
young parsons.  (21 references)

Between 1935 and 1947 the average yearly reported
incidence of childhood Pb poisoning was 15 cases
with an average of 5 fatalities per year.  In
1948 due to increased interest there was a sharp
increase in moroidity.  Since 1948 ^40 cases/yr
are reported, with the fatalities remaining fairly
stable.  The authors discuss incidence, source of
intoxication, seasonal variation, signs and symp-
toms and diagnosis of Pb poisoning.  The treatment
with CaNa2EDTA is discussed in detail.

A 3-yr-old child exhibited headache, vomiting and
asthenia.  Urinalysis showed the presence of gly-
cosuria (1-5 g/1000), phosphaturia and hyperamino-
aciduria.  The blood findings were 0.30 g/1 azotemia,
0.71 g glycemia (fasting), calcemia 100 mg, phos-
phatemia 15 mg/1 phosphatase 11.7 Bodanski units.
The findings which were diagnosed as Toni-Debre-
Fanconi syndrome, and signs which indicated intra-
cranial hypertension, led the author to seek a
toxic origin.  Chemical analysis revealed in
blood 2.5 mg Pb/1.  After BAL treatment all func-
tions returned to normal.  The hypothesis was
advanced that Pb poisoning may produce enzymatic
disturbances comparable to the syndrome of De Toni-
Debre-Fanconi.

                                              Pb poisoning has been reported in 143 children
                                              (151 hospital admissions) from 1950-1954 with 39
                                              fatal cases.  With better reporting and diagnosis
                                              the case fatality fell from 48% In 1953 to 15.2%
                                              in 1954, the 5-yr case fatality was 27.3%.  All
                                              cases were in children 56 yr of age with 67% of
                                              them in the 1st and 2nd yr.  There were 73 white
                                              children and 61 Negro children and 28 of Puerto
                                              Rican extraction.  The more likely number is 64.
                                              Eighty cases (56%) were female and, 63% were male.
                                              Of all the hospital admissions 60% were in the
                                              summer months of the year.  Pica occurred in 82%
                                              of the patients and in 9 families there were mul-
                                              tiple cases.  Most were reported from areas where
                                              the housing was substandard and where the hospitals
                                              were interested in the problem.

It is stated that "In order to treat Pb poisoning
in children adequately, it is necessary to consider
the factors which cause children to ingest Pb-con-
taining substances" since the eradication of these
factors is essential to cure the child of the pica
habit.  A basic study was made of 6 children with

 this habit, of age ranging from 18-38 mo who had
 been treated for Pb poisoning.  The study was made
 by means of 1 or 2 interviews with the mother,
 psychological studies of mother and child and a
 psychiatric playroom interview with the child.
 The tests, one or more of which was administered
 to each child, were the Minnesota Pre-School Scale,
 Gesell Developmental Schedules, Cattell Infant In-
 telligence Scale, Vineland Social Maturity Scale,
 Merrill-Palmer Scale of Mental Tests and Stanford-
 Binet, Form L.  From the results which are fully
 described it is concluded that factors which had
 contributed to the pica were the encouragement by
 the mother of the child's excessive oral activi-
 ties, significant separations of the child from
 its mother and emotional problems of the mother
 which interfered with a good mother-child relation-
 ship.  Economic and cultural factors, as well as
 factors of organic brain damage also contributed.
 Although the number of cases studied is small, the
 findings indicate the need for more intensive
 study to further our understanding of pica.

        SUBCUTANEOUS ADMINISTRATION OF A CHELATING
        AGENT.  Archives of Disease in Childhood
        31:321-3, 1956.
The theoretical basis of the use of CaNa2EDTA in
the treatment of Pb poisoning, the incidence and
causes of the disease in childhood are discussed
on the basis of reported cases.
  The usually recommended route, intermittent iv
administration of a dose JO.5 g/30 Ib/hr, involves
repeated infusions and in a plump toddler may be
difficult to carry out without cutting down on
veins.  Although sc administration has been re-
ported (Bessman et al, 1954), no discription in
detail of the administration has been given.
  The author describes the successful treatment of
Pb poisoning in 2 children ^2 yr of age with
CaNa2EDTA sc (0.25 g with 1500 IU hyaluronidase in
25 ml 1% NaCl solution over 30 min every 6 hr for
5 days.  Blood Pb concentrations dropped from 83
and 108 vg/2 to 50 and 30 (normal 10-30) .  In 1
child urinary Pb concentration was 280 vg/1 pre-
treatment, 700 after 2 days, and 220 after the 1st
course (normal 30-80 yg/1).  The spinal fluid glu-
cose and protein concentrations, the glucosuria and
amino-aciduria and the low Hb levels all returned
to normal.

         ROTHERdAM LEAD POISONING OUTBREAK.  Lancet
         2:113-6, 1956.
The outbreak of Pb poisoning at Rotherham in 1954
had been earlier described by Gillet (1955).  In
the present paper the clinical aspects are dis-
cussed and a number of cases described.  Only chil-
dren were affected, their ages varying from 11 mo
-15 yr, and no sign of Pb absorption was found in
125 adults from the same households.  The outbreak
was undoubtedly due to the use as domestic fuel of
scrap batteries, but poisoning was by ingestlon of
the residual ash and not by inhalation of fumes.
Ten children were severely affected, 2 of whom died
before diagnosis, and details are given of the 5
most severe cases.  The findings upon examination
of 140 others who appeared likely to have been at
Hazard are described, signs of Pb absorption being
found in 50.  The diagnosis of Pb absorption was
established from the following indications:  (1)
On radiography of the long bones, at the growing
ends of a shaft a dense line is visible, or in
younger children a broad zone of increased density,
due to the presence of closely packed trabeculae
containing a Pb deposit, this being best seen at
the lower end of the femur and the upper end of
the tibia.  Hence X-ray examination at the knee
would suffice as a screening test for the purposes
of a rapid, large-scale survey.  (2) Anemia,  with
diminution both in Hb content and in erythrocyte
count.  (3) Punctate basophilia, with stippled
cells forming 0.02% or more of the erythrocyte
count gives positive evidence of Pb absorption.
The stippling is not due merely to immaturity,
but to a specific effect of Pb on the cytoplasm
and cell membrane,  (4) Coproporphyrinuria.  Treat-
ment was with EDTA given iv in 2 5-day courses,
to a total dose of 12 g.  The technique is de-
scribed and details given of the resulting increase
in the urinary excretion of Pb in 3 of the cases.
In addition, Ma citrate and a high Ca diet in the
form of extra milk and Ca lactate together with
vitamin D, were given to help in the removal  of
Pb from the blood and soft tissues and promote  its
storage in the bones until fully excreted.  No
acute toxic episodes have occurred among 58 cases
of Pb poisoning or absorption followed up for 11
mo, but the possible effect on mental development
in the severely affected patients cannot yet  be
assessed.   (15 references)

Eight cases of Pb poisoning in children aged 7 mo-
9 yr were studied.  There were 2 deaths by enceph-
alitis.  The others suffered varying degrees of
poisoning.  In the case of the one family (3 chil-
dren) , the  source was an abandoned Pb foundry
where the children played; the other family lived
close to a  storage battery factory and here also
the children played in the yards around it.  Two
of them were treated with 2.5 mg BAL/kg, 4 times
daily, for  2 days and 2 times/day for the next 18
days.  In 4 cases 60 mg CaEDTA/kg/day, distributed
in various  doses over the day, were administered
orally for  20 days.  Tablets of 335 mg CaEDTA were
used.  The  clinical diagnostic criterion for Pb
poisoning was irritability, headache, vomiting,
constipation, abdominal colics and Burton's line
on the gums.  Anemia, basophilic stippling, de-
crease of hemoglobin, glycosuria and radiologic
changes of  the large bones were other signs.  In
7 cases EEC's were taken.  Results of clinical and
laboratory  tests for the 8 cases were listed.

        688-94, 1956.
In summarizing his review, the author states that
the predominant hematologic lesion of Pb poison-
ing is the faulty production of red cells and  Hb.
The developing immature erythrocyte of marrow  is
clearly much more susceptible to the noxious action
of this intracellular poison than are the marrow
cells.  The Pb appears to depress the conversion
of protoporphyrin into heme and to hamper the
formation of stroma in some of the red cells.   It
has not been feasible from the recorded  childhood
cases to derive any generalizations with respect
to significant relations between the severity  of
the blood change, the level of blood Pb  in random
test specimens, the age of patients, the duration
of exposure, or the intensity or character of  the
constitutional symptoms exhibited.  (From author's

A review article with 39 references.  The most
common source  of Pb poisoning in children is Pb-
containing paint.  A few cases have been due to
ingestion of wax crayons and inhalation of colored
chalk dust with Pb  in the pigment.  Some surface
glazes for porcelain and pottery contain minute
amounts of Pb  which may be dissolved if the con-
tainer is used for  lemon juice, vinegar or other
acids for several hours.  Pb pipes used in the
drinking water supply and Pb vapors occurring
from  the burning of discarded wooden Pb batteries
have  caused intoxication.  The incidence of Pb
poisoning in relation to  the age of the children
and to season  is discussed.  A relationship to
ultraviolet light was suggested but not establish-
ed.   The physiological picture, symptoms, diagnosis
                 and pathogenesis of Pb poisoning and its sequelae
                 and treatment are reviewed.

                 A Jamaican girl 21 mo old was admitted to the Uni-
                 versity College Hospital of the West Indies with a
                 5-day history of vomiting, weakness and drowsiness.
                 The symptoms and signs which are here recorded led
                 at 1st to the provisional diagnosis of encephali-
                 tis.  Later the diagnosis of Pb poisoning was es-
                 tablished because of persistent punctate basophil-
                 ia, the X-ray demonstration of marked Pb lines at
                 the metaphysis of all bones of the hands, wrists
                 and knees, and the finding that the urine contain-
                 ed 48 ppm of Pb.  Treatment by CaEDTA (300 mg iv
                 daily for 5 days and later 600 mg daily by mouth
                 for 9 days) was effective in bringing about great
                 improvement in the mental and general state.  The
                 source of the Pb was a smashed motor car battery
                 with which the child had been in the habit of
                 playing.  The child's elder brother aged 3 yr
                 though without symptoms was found to show evi-
                 dence of Pb absorption on examination of blood
                 and urine and by X ray.   (From Bulletin of Hygiene

                 Twenty-two boys and 14 girls between the ages of
                 15  and 56 mo with acute Pb encephalopathy were
                 treated with EDTA.  The disease was considered
                 severe in 14 patients who had convulsions contin-
                 uously for 24 hr or longer or remained comatose
                 for a similar period of time.  The disease was
                 mild in 22.  The drug was administered by contin-
                 uous iv infusion, continuous sc infusion, inter-
                 mittent sc injection, and intermittent im injec-
                 tion.  The total dose was the same in all patients
                 regardless of the route of administration; 75 mg/kg
                 body weight was given within 24 hr for 5 or  7 days.
                 Intramuscular injection of a 20% solution contain-
                 ing 0.5% of procaine HC1 was found to be the most
                 convenient method.  The interval between injec-
                 tions varied from 3-12 hr.   Five of the  36  patients
                 died and 4 of the 31 survivors were considered  to
                 have severe permanent damage to the central  ner-
                 vous system.  One of these children had recurrent
                 encephalopathy 3 mo after the initial mild enceph-
                 alopathy; recurrent convulsions occurred during
                 the subsequent 18 mo.  This was the only patient
                 in  whom reexposure to Pb occurred after the  ini-
                 tial attack of Pb encephalopathy.  One of the oth-
                 er  3 severely damaged patients had severe mental
                 retardation, another had a severe behavior dis-
                 order in the presence of at least average intelli-
                 gence, and the 3rd had severe brain damage super-
                 imppsed on a previously acquired defect resulting
                 from meningitis and hydrocephalus.  Four patients
                 had mild sequelae in the form of slight behavior
                 disorders.  The remaining patients, who were fol-
                 lowed up for 12-36 mo, did not show detectable
                 clinical abnormality.  These results were compared

with  those obtained in 33 patients with Pb encepha-
lopathy who had been treated at the same hospital
with  BAL between 1946 and 1951.  rfhile EOTA may
have  reduced the incidence of residual neurologi-
cal damage to a certain extent, it has not signif-
icantly reduced mortality from this disease.  EDTA
was no more effective than JiAL for quickly termi-
nating coma, convulsions, and increased intracra-
nial  pressure in acute Pb encephalopathy.  Most
of the deaths occurred during the period of these
manifestations.  The only present hope for a fur-
ther  reduction in mortality from Pb encephalopathy
would appear to lie in earlier diagnosis, prompt
removal of the child from exposure to Pb, and care-
ful supportive management during the first 48-72
hr of EDTA administration.  This duration of the
administration of the drug is required in severe
cases before the high toxic concentrations of Pb
initially present in tissues can be sufficiently
reduced to remove the danger to life.  The unpre-
dictable and fulminant manner in which acute Pb
encephalopathy may develop in children makes it
necessary that patients with both severe and mild
disease should be managed during the first few
days  of observation on the assumption that all
have potentially severe cases.  The first 6-12 mo
after removal from exposure to Pb constitute the
period of greatest risk of continuing metabolic
toxicity to cerebral and other tissues, in which
the concentration of Pb may remain high after an
initial course of EDTA.  About 25 mg of Pb was re-
moved from the urine during the initial course of
therapy with EDTA that was observed in the course
of 5 days in the patients; this may have consti-
tuted only a small part of the total Pb in the body.
Quantitative determinations of coproporphyrin
in urine were used as the principal biochemical
indication for repeated courses of chelation ther-
apy.   Prevention of reexposure to Pb in combination
with repeated courses of EDTA offers hope of reduc-
ing the incidence of more subtle but equally in-
capacitating forms of late damage to mentality.
Final conclusions with respect to such late damage
to the mentality of survivors of acute Pb enceph-
alopathy must await the reevaluation of these pa-
tients during the early school years.  (22 refer-

After an extensive historical survey of pica in
Europe and the Americas, the author discusses ori-
ginal observations concerning problems occurring in
Negro as well as white children of low socioeco-
nomic urban areas in Baltimore totalling 784, 172
of whom (21.9%) had a record of pica.  (All child-
ren under the age of 7 mo, ie, before inception of
crawling, were excluded from the study.)  Compared
to the non-pica group, the incidence of illness in
the pica children (16% in Negro, 17.9% in white)
was significantly higher than in the non-pica
children (9.5% in Negro, 8.1% in white).  Cases
of methyl salicylate poisoning and Pb poisoning,
occurring in the pica group in 2 cases each (med-
ical histories were not obtained on all children)
are not mentioned in the non-pica group although
one case of convulsions (etiology not specified
but probably not Pb-induced)  is included in the
latter group.  The author states that although the
reporting  is probably not complete, it neverthe-
less points to the pica group as the one carrying
the heavier burden of disease and physical defect.
The average number of behavior problems per child
in the pica cases was 4.4 for Negro, 4.5 for white
(total 4.4); for non-pica, 3.5 for Negro, 4.0 for
white (total 3.7), an increase of problems in pica
children statistically not significant, the slight
difference easily attributable to the greater in-
cidence of feeding problems in the pica group.
Comparison of intelligence tests between the 2
groups showed no essential difference in mental
status (2% of the pica children scored lower than
the non-pica children).  There was a marked prepon-
derance of Negro children over white in the total
group with pica (10.4%,SE ±2.94).  Boys scored
slightly higher in incidence than girls.
  Of all the pica cases in the present study, 15.1%
showed some paint ingestion.  If, as the study sug-
gests, pica is indeed a symptom of poor nutrition
(which, in turn, gives rise to anemia), etiologic
as well as symptomatologic treatment is essential.
Another factor for chewing objects may be emotional
neglect of a child or lack of play opportunities or
insufficient interaction with parents, siblings,
etc, in which the condition is not true pica but
closely related to it.  The survey also discusses
adult pica, occurring in Negro mothers.
  The author proposes 2 further studies:  (1) an
inquiry among private pediatric patients as to the
possible incidence of pica in various socioeconomic
groups;  (2) a study of a representative group of
antepartum patients to discover the presence or
absence of pica among them for studies of hemoglo-
bin and nutritional status.

        NINE MEMBERS OF A FAMILY.  Lancet  2:1096-7
        (Nov.  30),  1957.
A family of 11 members  (husband, wife  age  33 yr,
9 children 8 wk-14  yr) had lived for 4 mo  in a
galvanized iron shack in which  the previous owner
had broken down old car batteries to recover Pb.
The family had spread the Pb oxide which had been
left in a heap, over the earth  floor.  The sand  from
the floor was  analyzed and found to contain 16%  Pb
as Pb salts and dust from the rafters  contained
8.5% Pb.  A]1  except the husband and eldest boy,who
had spent little  time in the shack, showed signs of
varying degrees of  Pb absorption and Pb poisoning,
such as abnormal values for Hb, stippled cell count,
red cells, Pb  and coproporphyrins in urine.  Pb
lines were noted on gums and bones, the latter
proportional to the age of the  patient and rate  of
growth of the bones.  The author points out that
the presence of red cells in the urine may be an
important indication of Pb poisoning.  Treatment
with 60 mg/kg body  weight/day of CaNa2EDTA led to
recovery; only 1 boy (age 15 mo) still showed a
few erythrocytes  in the urine after 6  mo.

          AGEMENT OF LEAD INTOXICATION.   New York
          State Journal of Medicine 57,  No.  12:
          2394-6, 1957.
The author reviews his previous reports  on 18
cases (14 mo-3-1/2 yr of age) of Pb poisoning and
discusses the fate of Pb in the body following
the acute phase and following the action of BAL.
In 8 cases of acute Pb encephalopathy treated ini-
tially with Ca, inorganic P and vitamin  D, roent-
genograms of the long bones revealed that the Pb
deposits during the following 4-12 mo were in-
creasing rather than decreasing.  However, after
subsequent BAL treatment the Pb deposits in these
areas steadily diminished.  His theory of the fate
of Pb and effects of BAL are as follows:   After
Pb poisoning without subsequent treatment only
negligible amounts of Pb are excreted by the urine.
When left to its own devices nature seems to pre-
fer to store Pb in the bones rather than to ex-
crete it in the urine.  In some acute cases of Pb
encephalopathy, after treatment with BAL, Pb
seemed to increase in the bones.  The author
points out that in the acute phase BAL will mobi-
lize, bind and transport out of the body as much
Pb as possible while the excess streams  to the
bones.  Or it may be that Pb in brain, blood and
other tissues is more accessible to BAL  than that
in the bones and that the increased amount of Pb
in the urine during the acute phase derives from
these sources.  Continued action of BAL  will even-
tually send the Pb from the bones to the urine
and in chronic cases, BAL actually removed Pb from
the bones.  Prompt treatment with BAL in all cases
is advised since BAL appears to be a safe thera-
peutic agent.  (11 references)

"Dr. Davidson, in his article of Nov 30, accepts
almost by implication that the route of absorption
of the Pb from the remnants of broken-down car
batteries was inhalation.  In the Rotherham out-
break, on which you published my findings, I postu-
lated the theory that the absorption of Pb from a
similar source was due to ingestion and suggested
that the careless food hygiene of  the affected
children was responsible for this.  I wonder whether
Dr. Davidson has any evidence that this was the
route of entry in his cases."

        try 77, No. 1:70-8, 1957.
In 1953 and 1954, 46 children were hospitalized in
Chicago with chronic Pb poisoning; 90% of them
were 1-4 yr old and were mostly from poor families.
All of them showed pica and dried  peeling paint
was usually the noxious agent.  Of the 46, 43
children were first hospitalized with, the severe
or acute phase from May-October.   Most had a char-
acteristic premonitory syndrome of fatigue, extreme
irritability,  tearfulness, etc, followed by severe
stage, which included coma, convulsions, and  in
some partial paralyses.  Thirteen  died and the
                 surviving 33 were studied psychologically.  The
                 results  showed  that  27 were mentally retarded  and
                 in 20 of these  the retardation was directly trace-
                 able to  Pb poisoning.  One case could not be fol-
                 lowed .   Only 5  of the survivors were of normal in-
                 telligence.  Speech  was impaired in 18; most child-
                 ren developed emotional instability and became
                 very distractible.   Some had behavior problems be-
                 fore the poisoning.
                   Two years after their illness 14 of these child-
                 ren were tested a second time.  The 2nd year of
                 convalescence was one of recovery in some of the
                 cases (<50%).   However, the trend was not complete
                 enough to warrant optimism.  Prevention of Pb  poi-
                 soning is the only adequate solution.

                 Over  the period 1947-1956 the diagnosis of Pb  in-
                 toxication was made in 52 patients admitted  to
                 Cincinnati General Hospital.  Of these 52, in  only
                 18  cases there was no evidence of involvement  of
                 the central nervous system.  The diagnosis of  Pb
                 encephalopathy was made in 34 cases and only when
                 there was definite evidence of involvement of  the
                 nervous system.  Irritability and drowsiness were
                 not considered reliable.  The occurrence of  sei-
                 zures, however, is of significance in this regard.
                 Except for 1 case, this was usually substantiated
                 by  the finding of an elevated concentration  of
                 protein in the spinal fluid which was analyzed  and
                 recorded in 29 of the 34 cases.  Prior to the  use
                 of  massive cranial decompression 20 patients with
                 encephalopathy were admitted and later another  one
                 who was treated but not according to the prescribed
                 method.  Of these, 13 died (62%).
                   The 7 cases described here had reached a critical
                 stage for whom surgical decompression was neces-
                 sary; they were among 13 patients with encephalo-
                 pathy treated during the past 3 yr.  Their ages
                 were  18 1110-^4 yr.  The technique of the massive
                 bilateral decompression and subsequent treatment
                 is  described in some detail.  There were 2 deaths
                 (15%).  In 1, gastrointestinal hemorrhage was  the
                 cause.  Two survivors were mentally retarded.   The
                 authors conclude that the decrease in mortality in
                 these cases is due to extensive cranial surgery and
                 the use of EDTA as adjunctive therapeutic agent.
                 (EDTA has been routinely used in the treatment  of
                 Pb  intoxication in the last 3 yr.)

BIOLOGICAL ASPECTS OF LEAD

means for diagnosis resides in quantitative Pb
determinations in blood and urine.  Epiphyseal line
abnormalities may be present but are not diagnostic
of Pb deposition.  Similar X-ray disclosures may
arise in healing rickets and in connection with
restoration of Ca level after other nutritional
disorders.  If the epiphyseal line abnormalities
are present and if an exposure to Pb has been es-
tablished, then such bony changes could result from
the deposition of Pb compounds in the epiphyseal
areas.  In addition, some changes may arise at the
margins of the flat bones.  Rings of modified bony
density may appear in the ossification centers of
cartilage.  The intensity or breadth of the bands
or lines is influenced to some degree by the dura-
tion of Pb exposure and the quantity of Pb taken
into the body.  Diagnostic  methods other than
these X-ray changes should be pursued."

        (Nov.), 1957.
Health Department records in Cincinnati list 12
cases of Pb poisoning from January through Septem-
ber  1957, 3 of which were fatal.  During 1956, 16
cases with 2 fatalities were reported.  Usually,
the  patients are children under the age of 4 yr.
Whenever a case of Pb poisoning is reported, the
Health Department dispatches immediately an inves-
tigator who inspects the sanitary conditions, the
plumbing for Pb water pipes and sewage disposal
system of the home involved and obtains samples of
peeling paint and cracked plaster.  The information
and  samples are analyzed in the Kettering Labora-
tory and the results are then reported to the
physician in charge.  On the basis of the reports
of the Health Department, the Laboratory, the
Social Worker and the Nurses, an opinion Is formed
as to the tentative causative agent.

        Journal of Roentgenology, Radium Therapy
        and Nuclear Medicine 78, No. 3:547-9, 1957.
The  development of diagnostic aids in Pb poisoning
is discussed and the variations in the clinical
manifestations at different stages of life are
pointed out on the basis of  the literature.   A
small child can ingest appreciable amounts of Pb
without dramatic clinical manifestations until
sunlight is introduced which accelerates absorp-
tion and probably alters certain metabolic respons-
es.  The recognition of the Pb line at the ends
of growing bones in infants  and small children
proved to be an important diagnostic tool in
pediatrics.   Poisoning in childhood is usually due
to ingestion of paint from toys and furniture.
The  frequency of death during the acute phase of
poisoning could generally be ascribed to strong
intracranial pressure which  characterized the
meningoencephalopathy.   X-ray tests showed suture
lines literally torn apart.   Some children who re-
covered from Pb poisoning exhibited overt residual
damage of the nervous system, personality difficul-
ties and alterations in behavioral development.
Porphyrinuria and coproporphyrinuria offer a simple
and rapid biochemical screening test.  Therapy is
based on either increasing the amount of Pb de-
posited as inert phosphate or binding the active
fraction and encouraging its excretion.  The 2
most frequently and successfully used antidotes
are BAL and CaNa2EDTA.

A  discussion of the literature concerning Pb poi-
soning  in  children is presented.   In closing the
question is raised if Pb had ever  been used for
homicidal  purposes, since  nothing  could  be found
in the  legal literature.   A BBC play, however, had
a  husband  dispose of  wife  1 by giving her Pb, and
tried this on  wife 2  whose symptoms  did  not re-
semble  any Pb  case yet met; this reminded the
author  of  Bramwell's  (1931) statement that mis-
takes in the diagnosis of  Pb poisoning are often
due  to  not expecting.

        5  (Sept.), 1958.
A  comparative  study of several areas of intellec-
tual functioning in 2 groups (total  18)  of Negro
children treated either with BAL or EDTA in the
past 5 yr is presented.   All patients satisfied
the criteria for Pb encephalopathy:  convulsion,
lethargy or irritability, a pica history, blood Pb
values >0.05 mg% (0.052-0.53%), radiographic evi-
dence of heavy metal intoxication.  The 9 treated
with BAL (mean age 29 mo at hospitalization,  and
administered 3  mg  BAL/kg  for 12 days) were class-
ified as follows:   3 severely ill, 6 moderately
severe.   Those  treated with EDTA (mean age 26  mo,
and given 1 g EDTA/15 kg  iv for 5  days)  included
4 severely ill  and 5 moderately severe.   The  in-
terval between  hospitalization and the follow-
up averaged for the BAL group,  3.77 yr (range  3-5
yr) and for the EDTA group, 3.0 yr (2-4 yr).   The
results of the  IQ tests  (Binet and Goodenough)
when the children of the  BAL group were of mean
age of 5.74 and the EDTA group 5.1 yr, showed  means
for the 2 tests of 89.55  and 79.88, and 98.88  and
101.55,  respectively for  the 2 groups.   It ap-
peared those treated with EDTA were superior
on visual motor tests which were significantly
better than chance expectancy,  although no signif-
icant differences  were found between ratings  of
both groups in general intelligence which was
within normal  range.
  The authors  conclude that though it is  suggested
from the study  that EDTA may be more effective in
reducing undesirable psychological residuals,  the
possibility for their occurrence remains  despite
the type of treatment.

ingestion of peelings and flakes of paint as stud-
ied in Baltimore is reviewed (Bradley et al, 1956;
Bessman et al, 1954).  Since the disease is essen-
tially environmental, a concerted effort of physi-
cians, nurses and social workers is required.   The
danger of Pb encephalopathy, resulting in neuro-
logical sequela, mental retardation or death is
pointed out.

        Tennessee Industrial Hygiene News 15,  No.
        1:3-4, 1958.
Oral administration of EDTA in Pb poisoning in
children cannot be considered a substitute for
prevention of exposure to Pb.  EDTA acts as a
clinical "deleading" agent; but the process of
"deleading" does not seem to be the only factor
involved in the treatment of Pb poisoning.  EDTA
has not significantly reduced mortality from Pb
poisoning.  Compared to BAL, it seems to be more
effective in reducing the incidence of residual
neurological damage, but it is no more effective
than BAL in terminating the acute episode of Pb
encephalopathy.  EDTA blocks Pb that is continual-
ly released by tissues into the extracellular
fluids.  A period of 48-72 hr of EDTA administra-
tion is necessary to reduce lethal concentration
of Pb in the body to less toxic levels.  The drug
may be given by continuous iv route of a 2% solu-
tion or by intermittent intramuscular (im) injec-
tion in a total dosage range of 50-75 mg/kg body
weight/24 hr for 5-7 days.  Oral administration
of EDTA is not as satisfactory as parenteral ad-
ministration and may be harmful.  Im instead of iv
administration of EDTA helps in minimizing fluid
intake.  (Reprinted from National Clearinghouse

A 2-yr-old female infant who was known to have
chewed paint from the walls of a closet, was hos-
pitalized.  She had shown evidence of a moderate
pica for 2 mo prior to admission and had been
vomiting for ^3 wk preceding admission to the hos-
pital.  The child was listless.  Examination re-
vealed pallor of the mucous membranes of the mouth
and of the conjunctivae.  No gingival Pb line was
found but there was a questionable Pb line circum-
ferentially around the anal mucosa.  Blood tests
showed many cells with basophilic stippling, hypo-
chromia and moderate achromia.  A dose of 0,33 g
CaNa2EDTA in 5% glucose and water was injected iv
twice daily for 3 days and the same treatment was
repeated after a rest period of 3 days for 2 more
days.  Improvement started immediately; copropor-
phyrin excretion increased from 0.65-1.80 mg/1
after 1 day's treatment.  The mechanism of the
action of EDTA is discussed.  On the basis of
literature it is pointed out that though Pb is
adequately removed from soft tissues, it is only
partially mobilized in the skeletal components.
There is evidence that Pb may be deposited in the
bone marrow which suggests that further attacks of
chronic Pb poisoning might occur.  (10 references)

                 In a letter  (Abstract No.  2927) referring to the
                 author's article of Nov. 30  (Abstract No. 2925),
                 Gillett asked for evidence of the route of entry
                 of  the Pb.  No direct evidence was obtained. Ample
                 opportunity for ingestion  and inhalation existed.
                 Because inhalation is generally regarded as more
                 toxic, this route was considered more important.
                 Some confirmation of this  seems indicated by the
                 fact that the husband and  2  elder boys who spent
                 little time in the shack presented no evidence of
                 Pb absorption, but the wife  and younger children
                 who spent more time in the shack did.  As far as
                 contamination of food goes,  all members of the
                 family would have been at  somewhat equal risk.

                 Since 1955, physicians have  been urged to ask par-
                 ents whether the child or  any others in the family
                 had manifestations of pica.  If so, a careful ex-
                 amination with special reference to symptoms as-
                 sociated with Pb poisoning is made.  A diagnosis
                 of Pb poisoning is considered to be established if
                 the Pb concentration in blood >0.06 mg/100 ml and
                 2 or more of the following symptoms or signs are
                 present:  gastrointestinal,  neurologic, hematologic,
                 roentgenologic.  Pica cases  are concentrated in
                 the first 4 yr of age, only  4% occurring after
                 that.   3h 1956-57, 12% of  the pica cases occurred
                 in  infants <1 yr, without  any cases of Pb poison-
                 ing among them.  Pb poisoning in children leads to
                 death in 15-25% of the cases and to neurologic
                 disturbance in ^25% or more  of those that survive.
                 Early diagnosis is important.  Cases of Pb poison-
                 ing in children who do not have pica do not add up
                 to  a significant percentage.

                 Pb  poisoning was diagnosed in a 5-yr-old boy with
                 a history of vomiting, chronic constipation, anemia
                 and a stippled cell count  of 30,000/million red
                 cells.  A blood examination  of the other 4 members
                 of  the family showed mild  evidence of excessive Pb
                 absorption in the father and an infant child and
                 marked Pb absorption in another girl.  Treatment
                 with EDTA produced a marked  improvement of the blooc
                 picture in these 2 children. The Pb poisoning was
                 traced to the consumption  of a citric cordial which
                 had been kept in a jug with  a Pb glaze.  A quantity
                 of  the semi-dilute cordial,  left to stand in the
                 jug for 18 hr, upon analysis showed a Pb content of
                 400 ppm.

BIOLOGICAL ASPECTS OF LEAD

-------
The following incidents of Pb poisoning were re-
ported to the New York City Poison Control Center:
Five cases of children, 6 mo-2 yr old, who had
eaten paint and plaster for unknown periods of
time without the parents being aware of it.  The
children exhibited abdominal pains, vomiting and
fever, in some cases diarrhea, cyanosis stupor and
convulsion; all recovered.  A 6th child, 2-yr old,
died 24 hr after admission to the hospital.

Two case reports of Pb poisoning are given:  (1)
A  19-mo-old male child used to chew on the paint
of the window sill while looking out of the win-
dow,  ihe child had no symptoms until he developed
convulsions 4 days prior to his death.  (2) A 2-
yr-old male child who had a habit of eating paint
from the window sills developed vomiting and ab-
dominal pains.  A diagnosis of Pb poisoning was
not made until after the 3rd hospital admission
when he developed convulsions and coma.  General
symptoms of Pb poisoning, seasonal and geographi-
cal incidence and treatment are discussed.

Sloughed renal tubular epithelial cells containing

urinary sediment of children with acute Pb poison-
ing by means of staining smears of sediment with
hematoxylin and eosin or ^SO^-permanganate alde-

inclusions suggests that they are composed largely
of protein with a high content of cysteine of other
sulfhydryl groups.  (From authors' summary)

Description is given of the result of a pm exami-

renchymal lesions of the spleen and kidneys and
less in the placenta,  lungs and brain were ob-
served.   Quantitative Pb determinations were made
polarographically and colorimetrically after min-
eralization.   The Pb is conveyed to the fetus via
the placenta and is fixed in fetal organs without
being accumulated in organs performing antitoxic
functions.   (From Chemical Abstracts 53:14325,

        (May),  1958.
The concentration of Pb in the blood of 103 child-
ren,  5 hr-13 yr old, without history of Pb poison-
ing,  was  studied.  No relation  to sex or race was
detected.  For the purpose of evaluating the role
of age, the subjects were divided into 3 groups
ranging from (1)  5 hr-6 mo, (2)  6.1 mo-4 yr and
(3)   4-13 yr.  The values obtained for group 1
were  significantly lower than those for groups 2
or 3; ranges and medians for groups 2 and 3 were
practically identical.  Median  values in group 1
were  0.015 mg Pb/100 ml of whole blood (range
0.005-0.031) and 0.034 mg/100 ml of erythrocytes
(range 0.010-0.090).  Newborn infants had 0.007-
0.028 mg Pb/100 ml in whole blood and 0.010-0.044
mg/100 ml in erythrocytes.  Concerning the ques-
tion  of transport of Pb from the maternal into the
fetal circulation it is assumed that minute amounts
of Pb are carried by the maternal plasma into the
fetus.  In the combined groups  2 and 3 ranges and
median values were as follows;  in mg/100 ml:  whole
blood 0.003-0.054, 0.27; erythrocytes 0.003-0.144,
0.065; 90% of the values were between 0.015-0.040
for whole blood and 0.028-0.103 for erythrocytes.

In Issue No. 14, S.H. Osborn (Connecticut State
Department of Health) reported  the death from Pb
poisoning of a 3-1/2-yr-old boy, the possible
source of which was paint chewed from a crib.  Sam-
ples  of the original paint from the crib were found
to contain Pb.
  As  reported in No. 17, further study showed the
mother and 2-yr-old brother to  have high blood Pb
values (0.11 mg and 0.07 mg/100 g  blood,  respective-
ly),  while the father and 12-yr-old sister had nor-
mal blood Pb values.  It seemed unlikely that paint
from  a crib was responsible, and search for the
most  probable source of Pb in this case was con-
tinued.

were born and a 3-mo pregnancy ended in abortion.
After  treatment and change of occupation of the
father, 2 healthy normal children were born.
The literature is briefly reviewed.  Although in
this case the harmful influence of Pb was not
proved due to scarcity of laboratory data, the
Pb-intoxication of the husband is considered a
probable cause of the anomalies.  (From author's

mean hemoglobin of 7.6 g/100 ml, a moderate aniso-
and poikilocytosis.  Reticulocytes were >2% in 9
cases, with the highest value 10.8%; there was a

rin.  The findings were compared with those in nu-
tritional Fe deficiency.  (20 references)

         AND  REPORT ON 45 CASES.   Pediatrics 23:
         585-603 (March), 1959.
After a review of the literature concerning Pb  poi-
soning in children, 45 cases from the author's  ex-
perience are  described.   All were treated with  iv
or im administration of EDTA.  Oral administration
of EDTA produced no shortening of the prolonged
period of coproporphyrinuria following cessation
of iv use of  EDTA.  In the acute stage oral use of
EDTA was less efficient than iv or im administra-
tion in returning the aberrant porphyrin metabolism
to normal.   The conclusion was drawn that Pb inter-
feres with porphyrin metabolism at several physio-
logically distinct points and that the hematopole-
tic marrow is not freed of Pb by EDTA.  Since EDTA
given orally  in the presence of Pb in the intesti-
nal tract is  dangerous and even iv EDTA may promote
Pb absorption from the intestinal tract and its
transport to the brain, preliminary emptying of
the intestinal tract by enemata Is important.

        CHILDREN'S HOSPITAL, DISTRICT OF COLUMBIA.
        Journal of Pediatrics 54:271-84 (Mar.),
        1959.
Experience in the management of 43 children with
chronic Pb poisoning over the period 1950-1956
(with peaks in 1953 and 1955) is presented.
  The diagnoses were made on the basis of abnormal
blood or urinary Pb levels prior to treatment and
any of the 2 following abnormalities:  pica, baso-
philic stippling, markedly increased transverse
densities in the metaphyses of the long bones.
The children were grouped as to asymptomatic (28%),
                 with clinical symptoms without encephalitis (32%),
                 encephalitis (40%; 8 mild and 9 severe cases).
                 The frequency of signs and symptoms and diagnoses
                 made on admission is tabulated as well as detailed
                 laboratory findings.
                   The patients were treated with EDTA, administered
                 either iv, or sc (30 mg/kg/day as the standard
                 dose).  In the 1st 18 cases 0.5 g was given 3
                 times/day regardless of weight.  EDTA was given
                 for 5 days with a 3-day "rest" period and then re-
                 peated for another 5 days.  Three (7%) of the se-
                 vere encephalitics died after an average of 2-1/3
                 days.  At necropsy of 1 of them Pb analysis showed
                 in bone, 9.96 mg/100 g; kidney, 0.8; liver, 0.78;
                 lung, 0.10; brain, 0.0.  In the case follow-up,
                 the authors note that 1/4 of the patients were
                 lost; all but 1 returned to their parents and pre-
                 vious environments.
                   In their conclusions and summary the authors
                 state that the observed mortality of 7% is signi-
                 ficantly high even if it is an improvement over
                 earlier reports.  The 45% incidence of neurologic
                 and psychic residual morbidity found by them  is
                 pointed out for serious consideration and further
                 study.  Routine inquiry into the presence of  pica
                 may help to avoid the risk of Pb poisoning to be-
                 come symptomatic.  (35 references)

                 The case of a 2-yr-old white boy who died evi-
                 dently from Pb poisoning is described.  The fol-
                 lowing signs were indicative of Pb poisoning:
                 persistent vomiting, unsteady gait, changes in
                 the spinal fluid, anemia of a type typical for
                 Pb intoxication, coproporphyrinuria.  Against the
                 diagnosis of Pb poisoning was the report of a nor-
                 mal spinal fluid pressure.  The diagnosis was es-
                 tablished firmly on the basis of finding >1 yg Pb/
                 ml of bladder urine removed at autopsy.  The child
                 developed convulsions  and fever and died on the
                 3rd day in the hospital.  The Conference members
                 discuss whether prompt EDTA treatment would have
                 saved the child.  The  need for a law against the
                 use of Pb in house paints is pointed out.  Parti-

                 A case of acute Pb encephalopathy in a 19-mo-old
                 girl is presented.  The child was admitted to the
                 hospital because of lethargy and vomiting.  There
                 was a history of 3 mo's pica, the patient having
                 chewed on window sills and doors.  Blood tests
                 showed the presence of basophilic stippling; the
                 blood Pb level was 0.41 mg/100 ml; the Pb content
                 in  the urine was 11.80 mg/1 and 4.01 mg/24 hr
                 specimen.  X-ray tests showed some condensation
                 of  the inner table in the skull and transverse
                 lines of increased density in the metaphyses of
                 long bones.  EDTA was administered every 8 hr.

BIOLOGICAL ASPECTS OF LEAD

Convulsions, starting on the 3rd hospital day,
were followed by sudden death.  Autopsy revealed
encephalopathy due to Pb poisoning (edema and vas-
cular degeneration), cloudy swelling of the liver
and bone marrow hyperplasia.  A brief outline is
given of the etiology, clinical and laboratory
findings, diagnosis, prognosis, pathology and
treatment of Pb poisoning.  (24 references)

        Journal 44:156-60 (Apr.), 1959.
The cases of poisoning described occurred in a
colored family living in Lincoln, in a 2-family
house built in the early 1900's.  It was found that
^30 ft of Pb pipe led into the house with ^18-in
Pb pipe additionally from the meter to the house
piping proper.  Pb content in water, determined by
the method approved by the Public Health Service,
was 0.4 ppm before flushing and 0.03 ppm after
flushing.  Several weeks later the entire Pb piping
was removed; similar tests showed no significant
amounts of Pb.  The authors note that in their
locality, Pb piping was approved until the early
30's.  While much has been replaced, as of 1956
'vlO.OOO homes still had Pb pipe.
  Those afflicted were a boy born in 1953, a girl
born in 1954, arid their mother, seen by the authors
since 1951 (age 17).  Before Pb poisoning was di-
agnosed, the symptoms, aside from colic, irrita-
bility, etc,were a hypochromic anemia that did not
respond to treatment,  anisocytosis,  poikilocytosis,
and marked hypochromasia.  All showed severe stip-
pling of erythrocytes, and one, "target" cells,
but no Pb line on gums.  Urinary coproporphyrins
were positive in all cases,  Pb was 0.18, 0.13, and
0.21 mg/1.  The children showed the typical Pb line
upon bone X ray.  Inquiry revealed that the father
left home in the mornings without breakfast, and
that the mother used the tap water without flush-
ing.  The authors wished to investigate the other
family occupying the house,  where a small child
had been suffering from severe colic for several
months, but the family refused to cooperate.

        Centers:  LEAD POISONING IN CHILDREN:
        DIAGNOSTIC CRITERIA.  US Public Health
        Service, May, 1959, 8 pp.
Criteria to be used in diagnosing Pb poisoning in
children are presented.  Clinical and laboratory
criteria, criteria for Pb absorption, and exposure
to a Pb source are the 3 areas under which the
diagnostic criteria fall.  Two or more clinical
and laboratory criteria couples with 1 or both
criteria for Pb absorption enable a diagnosis of
Pb poisoning to be made.  Although chemical iden-
tification of the Pb source involved is important
in arriving at a final diagnosis, treatment must
not be delayed if the source is not readily demon-
strated.  A classification for final diagnosis
concerning the exposure of a child to Pb is recom-
mended.  The importance of recognizing early cases
of Pb intoxication and even earlier asymptomatic
cases in which increased Pb absorption occurs is
emphasized by the classification.  Use of this
classification should aid in establishing a long-
term prognosis.  Early diagnosis is necessary to

        (Feb.), 1959.
Three cases of Pb poisoning in children are de-
scribed.  They were 2 boys, 1-1/2 and 4-2/3 yr old,
and a girl 6-1/4.  The diagnosis of the condition
was reached at an early stage after admission to
the hospital because of the discovery of glycosu-
ria,  which led to further tests for Pb poisoning.
The glycosuria persisted for 3 wk.  There was no
evidence of residual renal damage at  the end of 6
mo.  All 3 cases were treated with prolonged
courses of oral CaEDTA resulting in prolonged ex-
cretion of Pb in the urine.  Evidence is put for-
ward to suggest that colored crayons  of the yellow
and orange ranges may be a danger to  children on
account of their content of Pb chromate.  (20 ref-

Pb poisoning among children is still  a serious men-
ace.   The source of the Pb nowadays is usually old
paint.  The illness primarily involves 1-4-yr-old
children and strikes almost entirely during the
summer months.  During the first 10 mo of 1958, 20
instances of excessive absorption of Pb by children
with 4 deaths were documented in Cincinnati.  The
case of a 2.5-yr-old girl is described in detail.
When the child started to vomit and to become le-
thargic, she was taken to the hospital where a
moderately severe anemia with basophilic stippling
of the red cells, the presence of albumin, sugar
and coproporphyrin in the urine, dense lines of
radio opacity at the ends of the long bones of the
forearm and large amounts of radio opaque sub-
stances in the intestinal tract were  found.  Al-
though therapy with EDTA was started  immediately,
severe encephalopathy ensued and the  child died.
Postmortem analyses showed the following Pb con-
tents (mg/100 g) in blood, liver, vertebrae and
feces, respectively:  0.64, 3.81, 14.9, 31.80 (on
ash.)

Red fluorescence of erythrocytes occurs during Pb
poisoning.  The authors examined microscopically
with  the aid of blue ultraviolet light a thin wet-
preparation of erythrocytes obtained from 7 un-
treated children with Pb poisoning, aged 15-36 mo.
In every one of these children the red fluores-
cence was observed in 75-100% of the  erythrocytes.
The exact nature of the fluorescent material in
the erythrocytes has not been determined; it is

probable that the fluorescence is related to the
amount of free protoporphyrin in the erythrocytes.
Control specimens (150) obtained from normal child-
ren and others with various clinical conditions
also were examined microscopically and showed 0-
50% fluorescent erythrocytes.  The authors con-
sider this test a simple, rapid and reliable meth-
od to aid in the diagnosis of Pb poisoning in
children.

ihe Organization of a Lead Information Center in
Cincinnati is described.  The agency was set up
with the purpose to coordinate the activities of
all community elements engaged in diagnosis,
treatment and prevention of Pb poisoning, because
of an increase of cases  (1 fatal case of encepha-
litis in 1946, but 72 cases of Pb poisoning with
5 deaths in 1959.  This has been due to greater a-
wareness of the problem.)  Whenever a case of sus-
pected Pb poisoning is reported, the city health
department sends a nurse and a sanitarian to the
child's home and blood specimens from the patient
and paint samples are sent for analysis to the
Kettering Laboratory.  In addition to its day-to-
aay operations the Center is hard at work on model
laws that will prohibit use of Pb-containing
paints in house interiors.  Meanwhile labeling of
all paints containing >1% Pb and local ordinances
compelling removal of Pb—aase paints in homes
where Pb poisoning has been detected, are advo-
cated.

Pb intoxication of aqueous origin in children is
not very frequent, and because it is exceptional
in French publications on Pb intoxication in child-
ren the authors presented this case of a 7-yr-old
girl.  The patient had no noteworthy antecedents
but suffered from severe abdominal pains and re-
peated vomiting since July 28, 1959.  Considering
a catarrhal infection, she was treated symptomati-
cally.   She improved for 5 days but as gastric
pains recurred with vomiting, she was hospitalized
on August 4.  Since there was no improvement and
her state of dehydration became worse, she was
given many perfusions per day.  Because  of many
similarities with Pb intoxication symptoms in
adults, a possible Pb poisoning diagnosis was made
on the basis that the girl regularly spent 1 mo/yr
in an otherwise uninhabited home in the country.
Drinking water was obtained from a well and only
this water was used.  It was led by Pb pipes to the
kitchen sink and the girl drank many times a day
directly from the faucet because of the heat.
  Laboratory findings showed the following:  uri-
nary coproporphyrins +++-,  urinary Pb level: 138
yg/100 ml (according to English authors, upper
                 limit of normal,  60 pg);  Pb content in the water:
                 180 mg/1.   She showed moderate anemia and no baso-
                 phillc stippling  was seen.   Opaque lines seen in
                 bone X rays gave  but vague  indication.  Treatment
                 with CaNa2EDTA was begun on the 4th day of hospi-
                 talization.  A 2  ml or 0.1  g diluted in a 50 ml
                 isotonic serum-glucose solution was administered
                 by iv infusion (2-3 hr) for 4 successive days.
                 The patient improved very rapidly and left the
                 hospital after 8 days.
                   The observation is thought to be worthy of in-
                 terest because  4 factors seemed involved:  (1)
                 Stagnant water in a Pb main for 11 mo (in 1957 as
                 much as 800 mg Pb/1 was found in a similar experi-
                 ment in Paris).  The well was located near a farm
                 so probably contained nitrates and chlorides which
                 change into Pb nitrates and Pb chlorides which are
                 very soluble.   The water in the region is very
                 poor in Ca so no protective cover of Pb carbonates
                 could be formed.   There was contact between the
                 water main and an electric cable which favored dis-
                 solution of Pb electrolytically.  (2)  In the ab-
                 sence of precise etiologic  information initially,
                 the almost peritoneal aspect could have resulted
                 in a surgical diagnosis.  (3)  Concerning therapy,
                 EDTA administration should  not exceed 4-5 days;
                 it appears to have better results with repeated
                 treatment some days or weeks later.  In the case
                 described the administration was not repeated.
                 The authors conclude with the question whether Pb
                 intoxication from water is  not less infrequent
                 than it is thought to be.

                 A qualitative technique is described for urine co-
                 proporphyrin (CP) estimation, (based on Schwartz's
                 et al method 1951,  the de Langen and ten Berg's
                 method, (1948, in which CP  is determined in ether
                 extracts of urine) having appeared to be unreli-
                 able in the hands of the authors).  The method,
                 described in detail, involved CP extraction.
                   It was then applied to the study of 258 children,
                 8-63 mo old, from June 1958-June 1959.  Among  them,
                 44 had acute poisoning, 52 had  increased absorp-
                 tion of Pb but were asymptomatic, and 162 showed
                 no evidence of increased Pb absorption according
                 to previously published criteria.  No cases with
                 a previous Pb poisoning history were included.  A
                 specimen was taken from each child and tested  for
                 CP within 15 min of voiding.  A blood sample was
                 taken and the blood Pb concentration was deter-
                 mined by a wet-digestion dithizone technique.
                   Some principles of porphyrin analysis are dis-
                 cussed and evidence is presented to show that  es-
                 timation of CP in initial ether extracts is not
                 reliable.  In using the reported technique, a
                 positive CP result (+++ or  I I I I) was present uni-
                 formly in patients with whole blood Pb levels
                 >0.10 mg/100 g, although in a number of the pa-
                 tients the abdominal and long bone X rays were
                 negative for Pb intoxication and the history of
                 pica was denied.   (16 references)

The incidence of Pb intoxication in children and
its differential diagnosis through radiological
detection of osteosclerotic changes are discussed.
The author points out that the skeletal changes,
although characteristic, are not pathognomonic of
Pb poisoning, for P, Sr or Bi besides Pb may be
responsible for the osseous changes.  Also F and
vitamin D may cause bone changes resembling heavy
metal osteopathies although the bone involvement
is more diffuse.  The conclusion is that if osteo-
sclerosis of the metaphyseal end of the long bones
is the only striking change, the probability of
heavy-metal osteopathy should be considered.  Such
findings, even without any supporting history,
should induce a clinical and laboratory investiga-
tion, in order to establish a definite diagnosis
of Pb intoxication.

A 17-mo-old Negro girl, when admitted to the hos-
pital with convulsions, had a  blood count as fol-
lows:   hemoglobin 9.0 g, hematocrit 30%,  leukocytes
15,750/mm-'.  The mother stated that her only pre-
vious seizure had come on 1 mo before and had
lasted a short time.  When symptomatic treatment
failed, CaEDTA was given intravenously on the 2nd
day.  The child died the following day after a 2nd
dose of EDTA.  Autopsy showed  a Pb content of 0.92
mg/100 ml in the brain but no  edema was present.
Blood analysis,  returned after the child's death,
gave a Pb level of 184 ug which,  corrected to a
hemoglobin level of 15 g, would give 478 pg.  The
case illustrates that advanced Pb poisoning can be
almost asymptomatic,

        PEELING HOUSE PAINT HAZARD TO CHILDREN.

        1960.
Between August 25,  1958, and October 10, 1959, a
total of 417  specimens of urine from children (5
yr and under, without  symptoms of Pb poisoning)
were analyzed for Pb at the Minneapolis Health
Department laboratory.  Of 393 samples obtained
through a screening program in well-child clinics,
7 showed high urinary  Pb (>0.08 mg/1).  Of the re-
maining 24 samples obtained from children living
in houses selected for study because of their
obviously peeling paint, 9 were found to be high
in Pb content.   Screening through the well-child
clinics lasted  nearly  14 mo, but the study in the
preselected homes was  carried  out only during July-
September .
  All  of the  specimens with high urinary Pb were
associated with  peeling exterior  house paint, ex-
cept for 2 cases found through the well-child
clinics.  In  these, the source of Pb was traced  to
Pb dust brought  home on the clothing of 2 adults
who worked in a storage-battery manufacturing
plant.  When the figures of the 2 studies were
combined, 14 out of 29 children living in 19
houses with peeling paint had high urinary Pb lev-
els.  All of these 14 children were believed to
have ingested the Pb although only 3 had a definite
history of pica.  The children played in the dirt
adjacent to the houses where peeling paint had fal-
len into the play areas.  None of the children with
high urinary Pb manifested sufficient signs or
symptoms to warrant a diagnosis of Pb poisoning
and by late October, almost all urinary levels had
returned to normal.
  Since all of the high urinary Pb levels appeared
during the summer, a seasonal outdoor exposure and
the absence of significant all-year inside ex-
posures were suggested.

Brief reports are presented on 10 cases of  Pb in-
toxication (all but 1 nonwhite) caused by pica in
children (age 1.5-4 yr) one of which was  fatal.
All lived in substandard housing and in nearly all
cases parents were unaware of the hazards.   Al-
though some of the children were asypmtomatic,
at the time of admission the blood Pb levels were
elevated in most cases.  The authors conclude by
recommending that an inquiry about pica be  made
a routine part of history taking, particularly
in children.

a 2-yr-old boy who had a 3-mo history of  vomiting,
weight loss, etc, and showed lethargy, papilledema,
nuchal rigidity, and right-sided convulsions.
X rays of the long bones revealed Pb lines, and
the abdomen showed metallic densities.  Skull and
chest films were normal.  Blood analyses showed
hematocrit 35%; white blood cells 13,500; Pb in
serum, 0.24 mg/100 ml; the urine contained  copro-
porphyrins which disappeared only after 2 courses
of CaEDTA, on the 30th day of admission.   Recovery
was complete after 38 days.

The case of Pb poisoning, due to ingestion of paint
peelings in a 5-yr-old girl is described.  The
child developed symptoms of respiratory infection,
vomiting, lethargy and clonic seizure.  Treatment
with EDTA was started and, in order to reduce the
pressure of the cerebrospinal fluid, 30% urea in
10% invert sugar  (1 g urea/kg of body weight) was
infused at the rate of 3 ml/min.  Marked diuresis
followed and the pressure became normal.

Five case reports are presented to draw attention
to the myocardial involvement in childhood Pb poi-
soning.  The myocardial lesions per se seem to
have been responsible for  the death of 2 of the 5
patients and certainly were contributory to the
death of the 3 others.   At autopsy evidence of Pb
encephalopathy was found in all, in addition to
chronic myocarditis.  The latter was characterized
by interstitial fibrosis with a serous exudate
and relatively few inflammatory cells.  Routine
electrocardiographic studies and close scrutiny
for possible clinical evidence of myocardial dam-
age is urgently recommended.

tive than CaEDTA (1 g/day) parenterally, in the
treatment of 2 children with Pb poisoning, 8 and

the urinary excretion of Pb.

        (Sept. 17), 1960.
A 1-yr-old girl with acute Pb poisoning developed
anuria and uremia 5 days after treatment with
CaEDTA (125 mg/kg of body weight daily for 3 days).
Her clinical course was complicated by pneumonia,
pericarditis, and bleeding from the gastro-intesti-
nal tract.  Despite artificial dialysis she died
after remaining anuric for 13 days.  At autopsy
the kidneys showed acute tubular necrosis, which
was attributed to the CaEDTA therapy.  It is rec-
ommended that the dosage of CaEDTA should not ex-
ceed 75 mg/kg body weight.  Similar cases have
been reported in the German literature and also
following the treatment of hypercalcemia with
Na2CaEDTA in US.  It is believed that the tubular
and glomerular changes result from the excretion
by the glomerulus and reabsorption by the proximal
convoluted tubule of CaEDTA or some metabolite of
that drug.   (From authors' summary)

The case of a 5-yr-old  boy who was admitted to the
hospital with abdominal cramps and colic was re-
                 ported.  The child was treated for hemolytic ane-
                 mia, dismissed after 4 wk, but had to be readmitted
                 1 mo later.  He showed a Pb line at the base of
                 the teeth, basophil stippling and density at the
                 metaphyseal margins of long bones, and died in
                 spite of immediate treatment.  On the basis of the
                 literature, the Pb content in blood, lungs, heart,
                 liver, spleen, kidney, stomach, intestines, urine,
                 brain, muscle, pancreas and bones in 15 subjects
                 (Pb exposed and controls) was tabulated.  Pb con-
                 centrations in the liver >0.15 mg% are considered
                 as pathologic but Pb intoxications are usually not
                 fatal until the Pb level in the liver exceeds 1
                 mg%.  A high Pb content in the intestines and in
                 the liver indicates acute intoxication while in
                 chronic poisonings the Pb concentration in the liver
                 is usually <1 mg%.  The Pb concentration in the
                 bone is indicative of the duration and intensity
                 of the Pb absorption.  The author points out that
                 generally there is no sharp demarcation between
                 normal and abnormal Pb content in organs.

                 Pb poisoning occurred in a 6-mo-old infant due to
                 prolonged use of  a Pb-containing ointment or lotion
                 for the mother's  nipples.  It is believed that Pb
                 was absorbed by the nipples and excreted in the
                 milk of the mother.  Intramuscular administration
                 of CaEDTA produced clinical improvement.  It is
                 pointed out that  some infants may develop subclin-
                 ical forms of Pb  poisoning and that the indiscrim-
                 inate use of Pb containing lotions and ointments
                 might be an etiological factor.  (From Journal of

                         Brain 83:411-24 (Sept.), 1960.
                 The courses of 6  out of 16 reported cases of fatal
                 Pb encephalopathy (4 colored, 2 white children)
                 that occurred in  Cincinnati from 1948-1957  are
                 briefly described.  Ages ranged from 21 mo-7 yr.
                 In all instances, the final illness was acute and
                 of short duration.  In some, there were indications
                 of previous episodes of less severe Pb poisoning.
                 In all except the 7-yr-old boy in whose case the
                 mode of poisoning was not clear, the route of in-
                 toxication was ingestion of dirt, putty, paint,
                 etc.  The dominant clinical feature was usually
                 increased intracranial pressure and acute cerebral
                 swelling.
                   The terminal episode in Case 1 (3-1/2-yr-old
                 Negro boy) lasted 4 days with rapid rise of intra-
                 cranial pressure  from 140-600 mm.  Positive signs
                 of Pb poisoning were a Hb of 6.5 g/100 ml, copro-
                 porphyrinuria, Pb lines in the bones and opaque
                 material in the abdomen.  Blood level was 0.26 mg/
                 100 ml.  In Case  2  (23-mo-old Negro boy) with a
                 history of pica), the final illness lasted ^3 wk,
                 Hb was 12.5 g, coproporphyrinuria, stippled cells
                 and Pb lines in the bones were present.  Blood Pb

level was 0.22 mg/100 ml.  Intracranial pressure
was 530 mm, protein In the CSF:  69 mg.  Patient
3, a 21-mo-old Negro boy, with a history of pica,
had a CSF pressure of 240 mm, protein, 50 mg/100
ml; Pb lines in the long bones, a blood Pb level
of 0.23 mg/100 ml, coproporphyrinuria and baso-
philic stippling of the erythrocytes.  A 2-yr-old
Negro girl (Case 4) had a CSF pressure of 600 mm,
protein 83 mg%, and Pb lines at the ends of the
long bones.  In the 7-yr-old white boy (Case 5),
the CSF showed a pressure of 360 mm, 10 lymphocytes
and 85 mg% protein.  Hb was 8 g.  The 6th case
(2-1/2-yr-old white boy) showed a Hb of 7.8 mg/100
ml, stippled red cells, a 4+ coproporphyrinuria and
Pb lines in the long bones.  Therapy with EDTA,
iv fluids, ACTH, craniectomy, decompression, etc,
proved futile in these cases.
  The pathology of the 6 cases, discussed in de-
tail, gave evidence that sub clinical cerebral epi-
sodes can occur with severe focal damage to the
cerebellar cortex to the walls of medium-sized and
small vessels, but not necessarily with significant
cerebral damage.  In the final illness the main
damage may be to the walls of vessels in the brain
and meninges with accumulation externally of a
serum-like exudate and marked dilatation of the
perivascular spaces.  Slight focal cellular in-
filtration, chiefly lymphocytic, is sometimes pre-
sent about the meningeal and cerebral vessels.
Although focal swelling of axis cylinders and mye-
lin sheaths is common, there is no pallor of mye-
lin staining or separation of the sheaths such as
occurs in the edema around tumors and in that of
alkyl Sn poisoning.  In occasional cases, the pic-
ture is complicated by severe early patchy necrosis
of the cortex and even of the deeper structures
(Case 4).  It is possible that this is brought
about by pressure on already damaged arteries and
arterioles by the swollen brain producing a vicious
circle.  When necrosis of groups of nerve cells is
very focal, eg, Ammon's horn in Case 3, the con-
vulsions may well play an etiologic role.  Pb con-
centrations determined in all cases were in mg/100
g: 7.6-18 in bone; 0.10-1.06 in brain; 0.88-2.0 in
kidney; 0.92-4.3 in liver.
  When feeding rats, using a dosage of 40 ppm of
triethyl Sn hydroxide in some animals, 80 ppm in
others, the authors were able to confirm the oc-
currence of a striking interstitial edema after
10-14 days at which time paraplegia followed by
quadriplegia and death was observed in a number of
the animals.  Clinical and anatomical recovery
followed in those from whom the poison was then
removed.  In those dying or killed with the fully
developed lesions, the volume of the spinal cord
appeared to be increased; this was not conspicuous
in the brain.
  Feeding experiments in dogs were for various
reasons not successful, but by repeated iv injec-
tions over a period of 4-5 wk in 2 animals, simi-
lar but not such marked lesions were produced in
the white matter.  In the 1st of these, ^-1 mg/kg
of triethyl Sn acetate was injected every few days
for 30 days; in all, 10 injections were given and
the dog was killed on the 34th day.  A short peri-
od of apnea sometimes followed the injection, and
stupor, or loss of consciousness, persisted for
as long as 1/2-1 hr.  EKG showed no significant
change.  In the 2nd dog, the dosage was ^-1 mg/kg,
given in 2 injections over a period of 25 days and
the animal was killed on the 29th day.  The dog
was agitated and ataxic for a time after each in-
jection but not unconscious.  EKG showed no abnor-
mality.
  Because of the absence of macromolecular sub-
stances in the interstitial edema of white matter
in these animals, it is considered that the edema
was a transudate rather than an exudate.  There
was no evidence that it was associated with damage
to the blood-brain barrier.  In the rats the edema
was sufficiently severe to produce increase in
volume of the spinal cord  (spinal swelling).  Au-
thors did not observe a detectable increase in the
volume of the brain in either the rats or the dogs.
If the lesions in the dogs had been of comparable
severity to those in the rats, an increase in the
cerebral volume would have been expected.
  In the discussion the authors sum up what is
known and unknown about the pathogenesis of these
2 contrasting lesions, ie, exudative edema and
cerebral swelling in Pb encephalopathy and trans-
udative edema in triethyl Sn poisoning.

The presentation of this report has been stimulated
by the occurrence of a relatively large number of
fatal cases of Pb poisoning in children in the age
group 1-3 yr.  Seven fatalities occurred in the
author's 350 bed hospital.  Incidence, causes and
diagnosis of Pb poisoning are discussed, and path-
ologic finding on autopsy are briefly described.
Aside from changes seen in the brain, in all cases
typical inclusion bodies were found in kidney sec-
tions, less frequently in those from the liver.
Also, highly abnormal amounts of Pb were found in
kidney and liver.

        25:309-15 (Feb.), 1960.
A case of chronic Pb poisoning is reported in which
a 3-yr-old girl did not show the usual signs and
symptoms of Pb encephalopathy but instead displayed
behavior disorders with progressive dementia.  Ex-
treme irritability, withdrawal, constant crying,
incoherent babbling, etc were observed in the for-
merly normal child ever since she had fallen from
her crib ^1 mo before admission to the hospital.
Analyses revealed 0.18 mg Pb/100 ml of blood and
urine strongly positive for coproporphyrins;
X rays showed Pb deposition beneath the epiphyses
of the long bones.  The child had frequently been
eating chipped paint from the porch, crayons, etc;
pica had been observed for ^2 yr.  Treatment with
CaEDTA brought effective clinical improvement.
But it is pointed out that the prognosis in this
patient must be guarded until time has permitted
an adequate evaluation of intellectual develop-
ment.  (20 references)

        CASE OF LEAD POISONING.  Radiography 26:

A 1-yr-old boy was admitted with drowsiness,
twitching in both arms, and stiffness in the neck,
and advanced bilateral papilledema.  Blood analy-
sis showed moderate anemia with a reticulocyte
count of 15% but no basophilic stippling of the
red cells.  Vomiting had persisted for ^2 mo.
X rays of the skull showed widening of the sutures
and the ends of the long bones showed an increased
density suggestive of Pb poisoning.  Since che-
lates were not available, the boy was treated with
Ca gluconate and Mg sulfate im, but he deterior-
ated rapidly and died the next day.  The mother
recalled that the child had been biting his paint-
ed crib for ^2 mo, and it was assumed that the
paint had probably contained Pb and had been the
cause of the fatal Pb intoxication.

        OF SUBCOMMITTEE ON ACCIDENTAL POISONING.
        STATEMENT ON DIAGNOSIS AND TREATMENT OF
        LEAD POISONING IN CHILDHOOD.  Pediatrics
        27:676-80 (Apr.), 1961.
Lead intoxication in children, occurring most fre-
quently between the ages of 1 and 3 yr,  is usually
caused by eating crumbling, peeling or easily
chipped paint.  Around 80% of symptomatic cases
occur during the summer.  The history of pica
should be considered in public health surveys,
even in cases where the occurrence of pica is de-
nied.  With rare exceptions, cases of pediatric
Pb poisoning occur in older sections of  urban
areas where old tenements or other dwellings have
been painted over 15-20 yr ago.  Pb is still found
in exterior house paints, particularly those speci-
fied as mildew suppressants.  Inhalation of Pb
fumes resulting from the burning of wooden battery
cases impregnated with Pb salts and swallowing Pb
medallions are additional causes of Pb intoxica-
tion.
  Pb poisoning in children manifests over a peri-
od of 3-6 wk by lack of appetite and lassitude,
changes in personality too vague to describe clear-
ly, and developmental regression to the point of
losing acquired skills, clumsiness, Incoordination
or ataxia.  Anemia may be present, but may be in-
dependent of Pb poisoning.  Constipation, abdomi-
nal colic and brief self-limited convulsive epi-
sodes may also occur.  Any chronic infection may
precipitate the symptoms of Pb poisoning acutely.
  If not recognized at this time, the Pb poisoning
may continue and rapidly lead to acute encephalop-
athy  with resultant death or permanent damage to
the central nervous system.  In older children
(>2 yr), recurrent, less severe episodes are more
likely, suggesting some degenerative cerebral dis-
ease.  Due to similar seasonal incidence, polio-
myelitis and Pb poisoning are sometimes confused.
In older children, peripheral neuropathy is a
characteristic finding.  Both mother and physician
may at first be misled into thinking that the child
has a severe functional behavior disturbance.
  Due to the paucity of positive physical findings
in early Pb intoxication, greater reliance must be
                 placed upon clinical history,  environmental factors
                 and laboratory findings.   Removal of the child
                 from the  environment may  be  necessary before lab-
                 oratory data are available.   Rapid screening pro-
                 cedures include X rays of the long bones and ab-
                 domen, hematol6gic studies for anemia and baso-
                 philic stippling of the erythrocytes, and urinaly-
                 sis for glycosuria, aminoaciduria and coproporphy-
                 rinuria.   If any of these laboratory tests are
                 positive, the child must  be  hospitalized and treat-
                 ed immediately.  Two successive determinations of
                 Pb in blood and urine should be obtained for defi-
                 nite positive findings.  In  general, a urinary Pb
                 content of >0.08 mg/24 hr, if obtained on 2 con-
                 secutive 24-hr specimens, would indicate excessive
                 Pb in the urine.  Two successive determinations of
                 50.06 mg Pb/100 ml of whole  blood would indicate
                 a positive finding.  In severely ill patients blood
                 Pb concentrations are usually >0.10 mg/100 ml of
                 whole blood.
                   Increased excretion of  Pb  during EDTA therapy
                 (1.5 mg or more in the urine on any one of the
                 first 3 days of treatment) is an additional factor
                 tending to confirm the diagnosis of Pb poisoning.
                   Methods of treatment, such as CaNa2EDTA parenter-
                 ally injected (in some cases preceded by saline
                 catharsis), hypothermia,  early surgical cerebral
                 decompression, and other  measures for the control
                 of convulsions, anemia, dehydration, etc, as well
                 as measures for the prevention of re-exposure,
                 are outlined.

                 CaNa2EDTA was  used in  the treatment  of  Pb intoxi-
                 cation in  2 children with pica  (a 17-mo-old  Cau-
                 casian female  and  a 23-mo-old Negro  male) and  in
                 1 adult  (40-yr-old Negro male) who had  drunk
                 "moonshine" distilled  in  old automobile radiators.
                 In  the children, a 24-hr  urinary Pb  of  0.14  and
                 0.22  mg, respectively, Pb lines  in  long bones  and
                 stippled erythrocytes, and  in the adult, 0.5 mg
                 Pb/1  urine, anemia with  stippled erythrocytes  and
                 abnormal electroencephalogram  confirmed the  poi-
                 soning.  Treatment with  EDTA was two 5-day  courses
                 (iv,  75 mg/kg/day) with  an  interval  of  3 days  be-
                 tween treatments,  and  60  mg/kg/day,  followed af-
                 ter cerebral  decompression  by  3  additional  5-day
                 courses, respectively, in the  children;  4  courses
                 of  2  g/day for 5  days  in the case of the adult.
                 In  all 3 patients  amino-aciduria appeared  in the
                 course of  EDTA treatment; it disappeared in  the
                 children after 2  courses  of therapy, but persisted
                 for >2 mo  in  the  adult.   This  condition is  dis-
                 cussed in  relation to  the findings  of proximal
                 renal tubular lesions  in experimental animals  and
                 humans treated with  EDTA.   The  author suggests
                 that  a-amino  N determinations before, during and
                 after EDTA treatment  may be important in assess-
                 ing proximal  renal tubular  function.  Should
                 amino-aciduria persist after a  5-day course  of
                 therapy, an increased interval  of  time  is  sug-
                 tested prior  to  another  period  of  therapy.
                    Discontinuance  of  EDTA treatment  of Pb intoxica-
                 tion is  not proposed,  but more  carefully con-
                 trolled  dosage and intervals of  therapy are urged.

 The author thinks that the Report of  the Subcom-
 mittee on Accidental Pb poisoning in  Childhood
 (Pediatrics  27:676,  1961)  should  have mentioned  the
 potentially  severe toxic effects  of iv CaEDTA.
 Some reports have noted aminoaciduria in Pb  poi-
 soning and attributed  it to  the toxic effect of
 the metal on the  proximal  tubules,  but did not
 state whether  aminoaciduria  was present before
 CaEDTA therapy.   He  therefore believes that  de-
 termination of amino acid  excretion before,  during,
 and after administration of  CaEDTA should be of
 help in gauging therapy, its dose and intervals
•between courses.   Lower dosage and shorter periods
 of  therapy should be used  in patients with evi-
 dence or history  of  renal  disease.

 The occurrence of Pb encephalopathy in children  is
 discussed on the  basis of  7  references,  and  it is
 pointed out that  this  condition should always be
 considered in  obscure  cases  of apparent encepha-
 litis or of raised  intracranial pressure in  child-
 hood.   Although in  the UK  the disease is consider-
 ably less common  than  in the US,  the  diagnosis is
 easily overlooked.   The discussion includes  treat-
 ment procedures,  such  as urea administration for
 the reduction  of  intracranial pressure.

The report deals  primarily with Pb  intoxication
 in  children, its  causes  and  the methods  for  its
 early  detection.   ihe  clinical and  laboratory
criteria for diagnosis  are outlined.   The use of
EDTA in treatment and  in diagnosis  of  Pb intoxica-
 tion,  its  routes  of  administration  and  dosage are
discussed.  Also  briefly mentioned  are  poisonings
 caused by  Pb arsenate,  Pb arsenite  and  TEL.

        TO USE  OF A LEAD NIPPLE SHIELD.)  Minerva
        Pedlatrica 13:617-22   (Apr. 21), 1961.
Stating first  that Pb poisoning is an  important
but little known cause of morbidity and mortality
in  infancy, the author reviews at  some length the
sources of such poisoning,  the signs and symptoms
and treatment.   Among the sources, 13  cases had
been attributed to the use of nipple shields
(since 1902).   The case reported is that of a
4-mo-old child  who '^20 days before admission had
become restless, stopped gaining weight, regurgi-
tated frequently;  these signs became aggravated to
the point that  at the time of admission she pre-
sented generalized tonic convulsions.   The infant,
nursed by the mother, had developed normally in
 the  1st  3  mo.
   Among  the  laboratory  findings,  a  qualitative
 test  for Pb  in  urine  was  highly  positive;  porphy-
 rin was  1200 Ug/1  (mother's  urine,  160);  radiology
 of the bones showed  typical  Pb lines.   Subsequent
 quantitative analysis of  Pb  in blood  gave 75  (Jg%
 (mother1;?  blood,  35).   The child was  treated  with
 iv infusions of glucose,  chloride and  plasma, vi-
 tamins,  barbiturates, cortisone,  Ca,  BAL,  anti-
 biotics  and  transfusions, etc.   On  the 15th day,
 Pb in blood  was 45 yg%.   In  closing,  the  author
 states that  the diagnosis in such cases is diffi-
 cult  because of the  intensity and variability of
 the  symptoms.   In  the discussion the  question is
 raised whether  the short  time the nipple  shield
 had  been used (2-3 wk)  was sufficient  to  cause
 poisoning  and that probably  other factors had in-
 tervened,   i'he  importance for an unequivocal  diag-
 nosis, the examination  of the blood,  X rays of
 bones, and analyses  of  Pb in the urine,  leces and
 blood, in  addition to clinical examination, are
 essential.

 From  Jan 1,  1959-Dec  31,  1960, 305  cases  of Pb
 poisoning  were  reported to the Chicago Board of
 Health and confirmed  by diagnostic  tests;  among
 them  1 was <1 yr old, 130 were 1  yr,  110,  2 yr,
 and the  rest, 3-4  yr.  All but 17 were due to in-
 halation of  Pb  fumes  from burning of  storage bat-
 teries.  There  were no  sex differences, but 273
 were  non-white.  There were  34 deaths,  or  1.04%
 fatality in  all poisonings reported in 1959-60;
 in 1959  Pb constituted  3.870  of all  poisonings and
 accounted  for 70.8% of  total  fatalities;  the cor-
 responding values  in  1960 were 4.06 and 737».  The
 highest  incidence  occurred in June-Sept.   So as
 to alert all physicians to the hazard,  the etiol-
 ogy and  epidemiology, signs and  symptoms,  diagno-
 sis,  admission  procedure, treatment, and  schedule
 of most  commonly used drugs,  and  the urine test
 for coproporphyrins, are  outlined.

        ITS MANAGEMENT.   New England Journal of
        Medicine 264:1027-30  (May),  1961.
 In 1959,  142 cases of Pb poisoning were admitted
 to Cook County  Children's Hospital.   Forty-two
were  diagnosed  as having encephalopathy of whom
 10 died  (23%);  in the 120, pica was  the cause and
 in 22, acute poisoning from the burning of  battery
 casings.   The ages were from  12 mo-5 yr, with the
 greatest number in the range  18 mo-3 yr (32) .
Thirty of  the 42 with encephalopathy,  received iv
 treatment with  urea.   These children were  the more
 severe cases.  Urea was administered as a drip of
 a  4%  solution in 5% dextrose in water, at  a rate
of =60 drops/min.   A 30% solution was used  in a
 few severe cases.   Three of  the cases are de-
 scribed.   CaNa2EDTA,  bilateral wide decompression
 and symptomatic therapy were also applied as indi-
cated.  The authors advise that EDTA should be
withheld  for 12-24 hr while  urea  is  being admin-

istered, and repeated cleansing enemas should be
given to remove Pb from the bowel before deleading
is attempted.  Of the 11 children who had decom-
pressions, ^50% died.  In general, these were late,
and at least 1 was a hopeless case.

        PORT OF 24 TREATED CASES AT CHILDREN'S
        HOSPITAL.  Clinical Proceedings  of  the
        Children's Hospital (Washington,  D.C.) 17:
        110-5 (Apr.), 1961.
A review is presented of 24 cases of chronic Pb
poisoning in children over the period Jan.  1957-
June 1959.  A history of pica was obtained  in all
cases.  The findings and results are compared with
a previous report on a similar group for the pre-
ceding 7 yr (Abstract No. 2952).
  The criteria used in defining Pb intoxication
differ from the previous report in that  1 or 2 of
the following should be fulfilled:  ^0.05 mg Pb/100
ml blood level or a urinary iO.08 mg Pb/1 before
treatment.  Of the 24 patients, 14 were  boys and
10 girls, all but one colored, ranging in age from
12 mo-^36 mo (1 >36 mo); 50% were in the 19-24 mo
age group.  Clinically there were 4 groups: asymp-
tomatic  37.5%; symptomatic 20.8%; mild encephalit-
ic  25.0%; severe encephalitic 16.5%.  Gastrointes-
tinal complaints (11 cases) along with neurological
complaints (9 cases) were the most common,  none
had fim-lines.   Laboratory findings showed that 75%
(18) had abnormally low hemoglobin levels,  (>10 g/
100 ml being considered normal; 86% in the  compari-
son study), and ^80% (19) had normal white  blood
counts (<15000/mm3).  Only 7 patients evidenced
basophilic stipplings (3 after repeated  smears).
Cohen and Ahrens' study had 50% with stippling.
Eosinophilia (>5%) was found in 3 patients  and 75%
(18)  had normal urines.  The 6 abnormal urines
showed proteinuria (2), glycosuria (3),  pyuria (4),
and hematuria (1).  Lumbar punctures performed on
11 patients gave normal values on 6, the 3 abnormal
patients being encephalitic and 1 being  traumatic.
Of electroencephalograms on 5 patients,  3 were ab-
normal.  In X rays of the long bones, 21 children
exhibited density of metaphyses.
  Treatment consisted of 30 mg EDTA/kg body weight/
24 hr, given by hypodermoclysis, every 8 hr for 2
5-day periods with an intervening 3-day  "rest"
period.  The results  are presented in a table.
Before treatment, 15 of the 24 had blood levels of
=0.05 mg/100 ml.  After treatment only 7 or 21 de-
terminations were toxic, but the blood level was
significantly decreased in almost all cases.  Uri-
nary Pb levels showed the same decrease.   Follow-
up examinations gave the following information: 1
death (previous study 3 of 43); pica ceased in 10
out of 19 following 1st course of treatment; resid-
ual findings in only 4 (45% in comparison report);
only 6 required repeated treatment, with 5 being
cleared of both symptoms and pica.

Statistical data are presented and analyzed in an
attempt to establish the control of Pb poisoning
                 cases  in  this  city  in  the  same  way  as  epidemic
                'infections were  handled  in the  past.   In the  'V>0
                 cases  registered yearly, Pb-containing paint  in
                 old  dwellings  is a  major factor,  but spot maps
                 and  field investigations suggest  that  other fac-
                 tors like obsolete  plumbing and air pollution,
                 as well as ethnic,  social  and economic patterns
                 may  be involved.
                   The  total  of 223  cases of Pb  poisoning with 41
                 deaths are  distributed in  a table according to
                 years  and month  of  onset,  and  in  other tables by
                 sex, and  by  race and ethnic group,  as  well as in
                 a bar  graph  according  to age in months; 197  chil-
                 dren were <4 yr.

                 A fatal  case of Pb  intoxication in an infant, 4
                 mo old,  caused by the mother's use of Pb-contain-
                 ing  nipple  shields, is described.  The child suf-
                 fered  from  cyanosis, persistent dermographia, hy-
                 pertonia, repeated  tonic-clonic convulsions and
                 bronchopulmonary complications.  Blood tests  show-
                 ed a slight anemia  but absence of basophilic ery-
                 throcytes.   The Pb  level in urine was positive
                 (no  data given).  Radiological examination did not
                 show any  bone alteration.   The distribution of Pb
                 in  the organs was:   (mg/100 g of tissue) liver
                 2.4; kidney 0.8; stomach and intestine 0.015;
                 spleen 0.05; heart  and lungs 0.5; femur  4; brain

                 A case of subacute Pb intoxication in a  7-mo~old
                 child is reported.   Intoxication was due to Pb
                 nipple caps.  Clinical  and laboratory  findings
                 showed hypertensive encephalopathy with  convul-
                 sion,  persistent vomiting, hypochromic microcytic

band of bony condensation.  There was an involve-
ment of the proximal tubules, with glucosuria,
massive amino-aciduria, hyperphosphaturia, citrat-
uria and rickets which constituted De-Toni-Debre'-
Fanconi syndrome.  Only 2 cases of secondary De-
Toni-Debre-J-'anconi syndrome in Pb intoxication
were reported in the literature.  The existence
of glucosuria with amino-aciduria, and hyperphos-
phaturia, without rickets, is less rare in the
acute stages of Pb intoxication.  The presence of
hypercitraturia suggests the identity, or at least
similarity of the enzymatic changes in the renal
tubules in Pb intoxication and in idiopathic
cases of De-Toni-Debre'-Fanconi syndrome.

        INTRAMUSCULAR EDATHAMIL CALCIUM-DISODIUM.
        Lancet 1:310-2 (Feb.  11),  1961.
The importance of pica in the history of a child
suspected of having Pb poisoning,  even if the oc-
currence of pica is denied by the parent, is em-
phasized.   Thus, treatment of pica and removal of
the source of Pb will serve to prevent further Pb
hazard.   Nibbling at painted cots, believed to be
a normal,  even necessary,  habit in the teething
stage by parents,  constitutes dangers usually un-
known to them.   Legislation concerning use of Pb-
containlng paints in the city of Baltimore and
England as a whole is briefly discussed.   The la-
tent symptom-free period in toddlers,  if nibbling
of paint continues, is ^3 mo during which Pb dis-
tributes in the  soft tissues, especially the brain.
Early diagnosis  is of utmost importance as contin-
ued exposure leads from pallor, irritability, con-
stipation, etc,  to refusal to eat, play,  stand, to
the final stage  of Pb encephalopathy with profuse
vomiting,  convulsions,  coma and usually death.
  In all cases of pica, the blood Pb level is >50
yg/100 g of blood.   The urinary Pb excretion is
increased >80 y.g/1/24 hr.   Since time is of the
essence, the authors list more rapid diagnostic
aids such as X rays of abdomen for radlopaque ma-
terial and changes in the long bones,  urine tests
for blood sugar, coproporphyrin and ALA,  and blood
tests for basophilic stippled cells.
  For the mobilization of Pb, CaNa2EDTA at a dose of
1 g/30 Ib of body weight/day (70 mg/kg)  is recom-
mended.   Intravenous (iv)  infusion of relatively
large amounts is dangerous, subcutaneous infusion
has similar disadvantages, and oral administration
is successful only in mild cases.   The home care
section of St.  Mary's Hospital is therefore using
the simpler intramuscular (im) technique (5% EDTA
solution with 0.5% procaine) which mobilizes as
much Pb as the iv method.   Survival and debility
rates are given from the literature and 2 typical
cases of Pb-poisoned boys thus treated and surviv-
ing are discussed, confirming the efficacy and
safety of im administration of EDTA.  In case 1,
patient aged 16 mo with anorexia, pallor, and other
signs  of Pb intoxication caused by chewing at his
cot  was treated with Fe therapy; prevention of
further Pb ingestion seemed to be beneficial.
Blood Pb level was 430 ug/100 g; urinary excretion
130 pg/1;  scrapings from the cot contained 6.5-10%
Pb.  EDTA was given im in a 5% solution in a dose
of 35 mg/kg, in 2 doses/day for 5 days at home.
Urinary Pb excretion rose to 430 yg/1, blood Pb
content 1 mo later was 70 yg/100 g, urinary excre-
tion 24 yg/1.  Three months after treatment,  the
boy was normal, but hemoglobin remained at a  level
of 8.3 g.  In  case 2, a 2-yr-old boy with vomiting,
anorexia and ataxia was admitted for glycostiria
with pica present, leading to the diagnosis of Pb
poisoning from playing with Pb toy soldiers.  A
5% solution of EDTA injected im to a total of 75
mg/kg/24 hr divided into 4 equal doses, for 5 days,
brought about  complete recovery.  One month later,
blood Pb was 35 ug/100 g.  Three months later, he
appeared completely normal (Hb 10.5 g) but baso-
philic stippled cells were still present.  Pica
ceased in both children, but the effect of Fe
therapy remains uncertain.

The mean Pb content (mg/100 g) of 82 deciduous
teeth removed  from "normal" children, 2-1/2-12 yr
old, 18 from 6 children dying of acute Pb encepha-
lopathy, and 13 teeth shed normally by 9 children
who had survived Pb poisoning, was found to be
1.51, 15.9 and 11.66, respectively.  Dithizone and
spectrographic methods were used, the accuracy of
which was within ±5%.  The Pb content of control
deciduous teeth was found to rise linearly with
time after eruption.  Both patients dying from,
and surviving  Pb intoxication had been treated
with versenate or other therapeutic agents.
  Further study is necessary to evaluate the re-
liability of Pb levels of teeth as an index of
the body burden of Pb.

Intoxications in breast-fed infants due to Pb nip-
ple protectors were unknown in Italy until 1959;
since then, 9 cases have been described in the lit-
erature.  The authors report the case of a 5-mo-
old female infant and also mention another recent
case in one 2-mo-old.  The child had developed nor-
mally till the age of 3 mo when, without apparent
reason, symptoms of anorexia and anemia, vomiting
and nervous disturbances appeared and the child
failed to gain further weight.  Upon questioning,
the mother stated that she had used Pb nipple pro-
tectors.  X-ray tests showed bone changes char-
acteristic for chronic Pb poisoning, and blood
tests revealed the presence of basophilic stippling.
The Pb content  (yg/1000) in blood, urine and spinal
fluid was 571, 75 and 181, respectively (normal
values, 200, 50 and 140-380, respectively).  A
diagnostic test with CaNa2EDTA (300 mg/50 kg body
weight, iv), after 10 hr, reduced the Pb concen-
tration in the blood from 500-135 Mg/1000 and in-
creased that in the urine from 100-216 ug/1000.
Urinary coproporphyrins were 0.242 mg/1 (normal,
100 yg/100 ml).  The pressure of the spinal fluid
was slightly increased.  The infant recovered com-
pletely after removal from further exposure to Pb
and 5 blood transfusions.

The Pb level in blood was determined in 116 chil-
dren,  age 1-37 mo and over,  who came from the slum
areas of Baltimore and had been seen to ingest
paint  from window frames  and doors.   Forty-three
(37%)  of these children had Pb concentrations
above  the upper limit of normal (0.06 mg/100 g).
Raised Pb levels in the blood were found  in a
higher proportion of  children during July  to Sep-
tember than during the rest of the year.   A rela-
tion was noted between the rise in the mean blood
levels in the summer and the rise in the monthly
hours  of sunshine and the mean daily minimum and
maximum temperatures.  (From author's summary; 15

        (Jan.), 1962.
Twenty-three children with acute Pb intoxication
were studied to ascertain the type, pattern, fre-
quency and severity of hyperaminoaciduria.  Results
                 were compared with patterns found in 56 patients
                 suffering from a variety of diseases which impair
                 renal tubular functions.  Amino acids in the urine
                 were determined by chromatography.  Hyperamino-
                 aciduria was classified as slight if 3-6 amino
                 acids were found in excess amounts, moderate at
                 7-10 amino acids and marked if >10 were found in
                 excessive amounts.  Ten of the children studied
                 showed marked, 5 moderate, 5 slight hyperamino-
                 aciduria while 3 showed no increase of amino acids
                 in the urine.  The triad of hypophosphatemia,
                 amlnoaclduria and glycosuria, known as the Fanconi
                 syndrome, was found in 9 of the 23 children.  In
                 all cases these abnormalities disappeared within 2
                 mo.
                    It is suggested that in acute Pb poisoning some
                 renal tubular mechanism common and essential for
                 reabsorption of all amino acids is impaired.  The
                 pattern of aminoaciduria resembles that found in
                 vitamin D deficiency rickets, cystinosis, Fanconi
                 syndrome of unknown pathogenesis, hyperparathyroid-
                 ism with renal calcinosis, and congenital renal
                 tubular acidosis.  The occurrence of fructosuria
                 and citraturia in Pb poisoning sets this disease
                 apart from other diseases giving rise to the Fan-
                 coni syndrome, and may suggest that fructosuria and
                 citraturia result from cellular injury caused by
                 Pb in still other areas.  (35 references)

                 A  case of acute Pb encephalopathy in a 6-yr-old boy
                 is presented.  Levels of Pb in blood and urine
                 were (yg):  280 and 780, respectively; coproporphy-
                 rins in urine, 78 ug CaEDTA at 0.5 g was adminis-
                 tered twice daily for 7 days.  On 2 occasions dur-
                 ing treatment the patient showed signs of intra-
                 cranial hypertension.  In both instances 100 ml of
                 30% lyophilized urea, which was given at a rate of
                 30 drops/min, produced satisfactory clinical signs
                 of decompression promptly and without untoward
                 effects.
                    Lyophilized urea therefore seems to be a poten-
                 tial useful adjunct in the management of Pb enceph-
                 alopathy.  A dose of 1-1.5 g/kg as a 30% solution,
                 administered at the rate of 60 drops/min, is rec-
                 ommended.  No harmful effects have been noted fol-
                 lowing its administration in >50 patients, other
                 than a mild phlebitis at the point of the injec-
                 tion.  Since normal blood urea levels range from
                 20-30 mg/100 cm^ and toxic levels may be reached,
                 the use of lyophilized urea is not recommended in
                 cases of renal damage.

 the 1st case, a serious encephalopathy set in after
 a period of dyspepsia and failure to gain weight.
 In the 2nd infant, intercurrent purulent meningitis
 aggravated the anemic syndrome.  Both infants show-
 ed an increase in the urinary excretion of phos-
 phorus without glycosuria.  After iv treatment with
 tDTA  in doses of >100 mg/kg/day most symptoms
 regressed.  The importance of a careful investiga-
 tion of the history of breast-fed infants in order
 to prevent and discover Pb poisoning, is stressed.

 In 25 severe cases in children, 15-36 mo old, out
 of 101 cases of acute Pb encephalopathy, observed
 in the authors' hospital during 1959-61, the med-
 ical treatment with urea and CaNa2EDTA was sup-
 plemented with bilateral flap cranlectomy   Most
 of the children prior to the operation had been in
 coma, respiratory arrest occurred in 8, and all
 but 2 entered the hospital with convulsions.  Mor-
 tality in these 25 cases was 64% as compared to
 31.6% in the total group of 101 children.  A 2-yr-
 old, apparently moribund child, who suffered from
 generalized convulsions and coma, resulting from
 ingestion of Pb-containing paint, recovered after
 a craniectomy supplemented by EDTA treatment.  No
 conclusions were drawn as to the place of surgery
 in the management of Pb encephalopathy.

The Hawaii Poison Control Center has recorded only
 3 cases in the past 5 yr.  Two cases of Pb poi-
 soning are described, 1 in a 3-yr-old girl, ad-
mitted to the hospital in December 1961 because of
recurrent vomiting of ^5-day duration.   The diag-
nosis was made on the basis of history of ingestion
of paint chippings, laboratory,  clinical, and X-ray
 tests.  Treatment was with CaNa2EDTA.  The other
case, a 21-yr-old man,  employed in a Pb foundry
 and handling battery casings, was admitted to the
hospital in October 1959 with abdominal pain and
vomiting.   Removal from further exposure to Pb and
supportive measures brought him to prompt recovery.
  The principal signs and symptoms of Pb poisoning
are summarized and treatment is outlined.

The etiology,  diagnosis and treatment of Pb intoxi-
cation in New York City in children <2-6 yr and
over,  in the months  of  Jan-Oct in 1961  was com-
pared to that  in the  same period  in 1960.   As tab-
ulated for white,  non-white and  Puerto  Ricans,
the number of  cases for those years were,  respec-
 cively:   <2 yr,  54 and  32;  2 yr,  61 and 58;  3 yr,
22 and 21;  4 yr,  9 and  5; 5 yr,  4 and 5;  6 yr and
over,  3 and 2.  The totals of 153 and 123 did not
include 83 possible Pb poisoning cases  reported in
1961 and 20 such cases  in 1960.   There  were 6 fa-
 talities in 1961 and  13 in 1960,  all in non-white
and Puerto Ricans.  The Pb poisoning study group
decided to do urinary coproporphyrin screening
tests on all children under 6 yr of age  in the "Pb
belt," ie, the area with the highest incidence of
Pb poisoning, and to subject to Pb determination
in the blood all those who reacted positively.
All children showing a Pb level in the blood of
0.06 mg/100 g and over are referred for  further
investigation and treatment,

Among the cases reported, a case of Pb intoxication
in a 2-yr-old girl, caused by ingestion  of painted
plaster, was complicated by ascariasis.  The pa-
tient suffered from abdominal pain, underweight,
and anemia.  Laboratory findings showed  Pb levels
of 0.07 mg/100 ml in blood and 0.06 mg/1 in urine;
Hb, 9.4 g/100 ml; 3.3 million red blood  cells.

A boy, 5 yr old, an illegitimate child,  had been
admitted to the hospital with constipation, an en-
larged liver and hemolytic anemia.  After improve-
ment by appropriate treatment he was discharged but
33 days later had to be readmitted in very bad
condition.   He was vomiting and having abdominal
colic.   Basophil stippling was found in his blood
smears and X-ray films of the wrist revealed heavy
Pb lines.   In spite of treatment he died a few
days  later.   His blood contained 0.92 mg Pb/100
ml;  the Pb content of his liver, kidneys and bones
was 20,  40 and 8 times,  respectively, of the nor-
mal value,  the Pb concentration of urine and
feces was  tremendous (1.82 mg/350 ml, and 0.23 mg/
g) ,  the fluid in the ileum contained 16.6 mg Pb.
(The  dithizone method was used.)  Apparently the
child had  been given a Pb-containing substance
with  criminal intent.
  A review of the incidence,  sources, signs and
symptoms and treatment with BAL and EDTA as re-
ported  in  the literature precedes the presentation
of  the  above case.   (28 references)

Apparently the use of nipple shields as  a cause of
Pb poisoning in infants is unknown in Italy and
other Latin countries.
  Some recent reports of this are reviewed.  When
a Pb  nipple protector was partly immersed in 20 ml
of milk at 37°C for 48 hr, the milk was found to
contain 0.74 mg Pb.   It has been stated but not
proved that the mother's milk contained Pb for >1
wk after she had discontinued the use of Pb
shields.  Infants up to 3 yr show gingival hem-
orrhages but not the Pb line typical for adults in
Pb poisonings; absent are also neuritis and poly-
                                                                                                     599

radiculitis.  But these infants show alterations
of the fundus of the eye which are rarely observed
in older children.  The 1st manifestations in in-
fants are irritability and disturbances of the
gastrointestinal system such as vomiting.  A hypo-
chromic anemia with stippled basophils and nervous
convulsions follow, and there is an increase of Pb
in the blood, urine and feces.  The present treat-
ment consists of oral or iv administration of EDTA.
  The author recommends that nipple shields be in-
cluded in the health laws forbidding the sale of
articles containing Pb, for pediatric use, and that
the provincial health departments conduct an edu-
cational campaign concerning the dangers to the in-
fants by the use of Pb-containing nipple protectors.

Pb poisoning of a breast-fed 1-mo-old male infant
is reported.  The family used Pb acetate for water
proofing purposes.  The infant developed severe
anemia, porphyrinuria, epiphysial Pb line and
stippled basophils in the blood.  Six cases of Pb
poisoning in infants in Japan, which occurred dur-
ing the last 15 yr, are reviewed.  The possibility
of Pb poisoning in cases of infantile anemia of un-
known etiology is pointed out.  (From authors'

Roentgenologic studies were conducted in 48 child-
ren treated for Pb poisoning.  Among the 48 child-
ren there were 10 pairs of siblings including twin
brothers.  Metaphyseal dysplasias of various de-
grees were found in 24 children.  While metaphyse-
al dysplasla had long been regarded as of familial
origin, the transverse lines of increased density
occurring in the long bones in such cases, as de-
scribed in the literature, were identical with
those observed in Pb intoxication and were be-
lieved to be due to the latter condition.  Repre-
sentative cases are illustrated.  In none of the
series described here were similar dysplastic
changes seen in the parents and other relatives
who had X-ray examination.  (From authors' sum-

                 X-ray examinations of 511 children from nurseries
                 and kindergartens, situated in the vicinity of a
                 Pb-processing plant, revealed  64 cases with in-
                 filtration bands in the zones  of preliminary calci-
                 fication of thigh, shin, forearm, and hand bones.
                 Differential diagnosis showed  the infiltration bands
                 to be due to Pb deposits in bone tissue.   Analysis
                 of urine from 31 children revealed that Pb was
                 contained in the urine of 21 (0.01-0.028 mg/1 in
                 14 and >0.04 mg/1 in 7) and traces of it were
                 found in 6.  In the control group of 21 children,
                 only 1 child showed traces of  Pb in urine.  The
                 Pb-carrier state was caused by industrial dis-
                 charges containing Pb.
                   Spectrographic analyses of 60 samples of soil and
                 of 15 samples of cabbage grown on the same soil
                 showed concentrations of Pb in the ash of 0.56-
                 0.81% and 0.152-0.4%, respectively.  Consequently,
                 X-ray examinations of certain  parts of the skele-
                 ton may be recommended for the purpose of early
                 detection of a Pb-carrier state in children who
                 are living in, or frequenting, institutions for
                 children situated in districts located near Pb
                 processing plants.

                         Journal 55:1184-6 (Nov.), 1962.
                 The author emphasizes the seriousness and frequency
                 of Pb poisoning in children and the difficulty of
                 diagnosis.  In the period 1944-1957, 4 cases were
                 hospitalized in the Children's Medical Center.  In
                 the 3 yr from 1958 when interest had been aroused,
                 19 cases were diagnosed.  The  author compares the
                 symptoms and laboratory findings in 11 of these
                 cases which were suspected, and in 8 with classi-
                 cal symptoms.  Since no data were available on the
                 amount of Pb excreted by normal children after
                 EDTA administration, this diagnostic test was
                 applied, using a dose of 75 mg/kg im to (1) 24
                 normal children, (2)  the 8 with classical symp-
                 toms and (3)  the 11 suspected cases.  In Group 1,
                 pre-EDTA urinary Pb values ranged from 0-160 yg/1
                 (av 15 yg/1), and post-EDTA 4-405 Mg/1 (av 165
                 Vig/1) ; in Group 2, the corresponding values were
                 0-500 yg/1 (av 146 Mg/1) and 971-3030 yg/1 (av
                 1966 ug/1) .  In group 2 there  were 2 children who
                 had received previous EDTA treatment; although
                 their pre-EDTA values were within the normal
                 range, their post-EDTA values  were extremely ele-
                 vated.  In group 3 pre-EDTA Pb excretion was 0-35
                 yg/1, thus below the accepted  abnormal values
                 (1 of them showed 120 pg, but  showed no classical
                 symptoms); post-EDTA, 608-1570 yg/1 (av 995 yg/1).
                 A urinary Pb excretion of >500 yg/1 was considered
                 as indicative of excessive ingestion of Pb-con-
                 taining substances.

 Twenty-four normal children, average age 28 mo, 11
 children, average age  25 mo, with suspected Pb in-
 toxication, and 8 children, average age 24 mo,
 with  classic  signs and symptoms of Pb intoxica-
 tion, were  injected im with 75 mg/kg of CaNa2EDTA
 in  a  20% solution, divided in 3 doses at 8-hr in-
 tervals.  Average urinary Pb levels in the 3
 groups before administration of the drug were 15,
 24, and 146 ug/1, respectively, compared to 165,
 995 and 1966  ug/1, respectively, after EDTA admin-
 istration.  The authors conclude that the EDTA
 test  provides clear-cut differentiation between
 normal individuals and those with increased expo-
 sure  to Pb.   Urinary excretion of Pb of >500 ug/1
 is  an indication that there has been excessive
 ingestion of  Pb-containing substances.  (13 refer-

 Red-Hook-Gowanus Section of Brooklyn, N.Y.   Eight
 blocks were selected as a pilot study.  Volunteers
 visited families with children living there and
 interested them in having their apartments painted
 free  of charge.  Other tenants were offered free
 paint to do their own apartments.  So far,  19
 families have repainted their  homes with Pb-free
 paint.  The project may be expanded to other parts
 of Brooklyn.

 For the diagnosis of Pb poisoning in children the
 following 4 criteria must be considered:  (1)  the
 presence of the source of the  poison, (2)  clinical
 findings,  (3)   indications of  Pb absorption and
 (4)    laboratory findings.  In  referring to the
 case  of a serici,sly poisoned infant, the author
 points out that deduction rather than induction is
 helpful to detect the source of the poisoning.
When  the mother talks about a  small battery repair
 shop being operated within their dwelling place,
 the physician may suspect Pb poisoning.  Ash from
 chimneys of factories (as in a recent case of an
 endemic area), paints, toys may contain Pb.  Tap
water, especially that drawn from new pipes, may
 dissolve Pb from these pipes;  the practice of con-
 necting electric cables to water pipes facilitates
 such  ionization.  Carbonated water siphons, wrap-
 pers  for chocolate and other candies often contain
 Pb.   Clinical findings include neurologic,  gastro-
 intestinal, hematologic and urinary anomalies.   Pb
 absorption in children is detected by X rays of
 the long bones showing radiopaque densities and
 by the presence of >10 ug% of  urinary coproporphy-
 rin.  Laboratory findings include the determination
 of  Pb  in blood  and  urine.  A  content  of  up  to  0.6
 mg  Pb/100  g blood is  normal while  0.06-0.08 mg%
 indicate an increased absorption.  The  threshold
 limit  for  urine is  0.08 mg/24 hr.  Signs and symp-
 toms of Pb poisoning  and  treatment with  EDTA are
 discussed.

 The literature  on Pb  poisoning is reviewed  on the
 basis  of 53 references and results of a  study on
 7 children, 1-3  yr  old, are reported.  All  7 had
 histories  of pica and their poisoning occurred
 during the summer months.  The urinary level of Pb
 was above  the normal  of 0.05 mg/100 ml/day  in all
 7;  3 showed changes of the central nervous  system.
 X-ray  studies showed  radiopaque densities in the
 gastrointestinal tract and an  increase in meta-
 physeal densities in  5.  Basophilic stippling was
 found  in only 2  children, 3 showed microcytic and
 and hypochromic  red blood cells.  Three  had ele-
 vated protein.   EDTA  was administered orally or iv
 at daily doses  of 65  mg/kg for 5 days or in 2 or 3
 courses of 5 days each.  A 5-day regimen of 75 mg/
 kg/day of EDTA  in 100-200 ml of 5% dextrose in
 water, administered in 2 equal doses  at  a 12-hr
 interval,  is recommended.

The frequency and distribution of Pb poisoning in
various countries is  discussed.  There is no spe-
 cial legislation as  yet in Colombia but  the indus-
 trial physicians are  striving  to eliminate Pb
hazards in industry.  Etiology, physiopathology,
 anatomic pathology,  signs and  symptoms of acute and
chronic Pb poisoning, diagnosis and treatment  are
discussed and 6 cases of Pb intoxication in thi;
same family,  due to  inhalation of Pb oxide,  are
 reported.  The family  lived in a Pb foundry all
 together in a single  room close to the workshop.
Both the 52-yr-old father and  the 36-yr-old mother
 suffered from abdominal colics and vomiting.  They
had 13 children of whom 9 had  died at an early age.
Surviving were 3 girls, aged 3, 12 and 17 yr and a
boy of 6 yr.   All had digestive symptoms; with ex-
 ception of the son,  all had cardiovascular symptoms,
and all but the father signs of disturbance of the
central nervous system.  Encephalitis had been
diagnosed in the 3-yr-old girl.  Hb was decreased
 in all cases  and the number of stippled erythro-
cytes was elevated in all except the youngest  girl.
  It is pointed out  that physicians should be  aware
of the fact that Pb  poisoning  occurs not only  in
adults working with  Pb, but also in children who
ingest Pb paints from toys and walls, and other
sources.

        14:459-61 (Aug.),  1963.
A case of subacute Pb poisoning  in a 3-yr-old child
is reported.   One month before the diagnosis was
made, the child developed Irritability,  pallor,
anorexia, and lost weight.   The  condition became
aggravated by vomiting, fever, lipothymia and en-
cephalitis.  Blood tests showed  the presence of  3
granulated basophils/1000 red cells.  Pb poisoning
was suspected since the child was the son of a. var-
nisher and had been seen to ingest Pb-containing
enamel, such as red and white Pb.  A roentgenogram
of the skeleton showed radiopaque bands of the long
bones, particularly of the forearm, leg and knee.
Treatment with EDTA (200 mg daily for 2 wk) re-
sulted in recovery within 20 days.  The differences
in the symptomatology of Pb poisoning in infants
and children versus that in adults are discussed.
The manifestations in the former begin with loss
of weight, pallor, irritability, anorexia, dys-
pepsia, followed by abdominal colics, vomiting and
afflictions of the central nervous system, while in
the adult mainly the peripheral  nervous system is
involved.  There is a hypochromic anemia, basophil
granulations in the red cells, increased free pro-
toporphyrin in the blood and coproporphyrin in the
urine; albuminuria and cylindruria are less evident
in children than in adults; glycosuria occurs only
in rare cases.  The gingival line which is common
in the adult and rather frequent in 2-3 yr old
children, has not been observed  in the newborn and
infant which, however, show gingival bleeding.
Polyradiculitis and neuritis are absent in the 1-
yr old, but occur in older babies.  The Pb contents
of blood and urine are elevated  throughout the
whole period of intoxication and for several months
thereafter.  The bone lesions caused by Pb are
visible only radiologically and  do not produce
clinical manifestations.  The diagnosis of Pb poi-
soning in the infant is difficult, particularly in
the absence of precise anamnestic data, and the
syndrome is similar to that of many infantile dis-
eases.  The most reliable indication is the pre-
sence of condensed metaphysial bands seen upon
X ray of bones.  Treatment consists in administra-
tion of EDTA.  Mild cases recover completely,
graver ones may lead to psychic  disturbances,
chronic nephritis or death.

        NECKLACE.)  Pe'diatrie 18, No. 2:143-70,
        1963.
Pb intoxication in children is much less frequent
in Latin countries than it is in the Anglo-Saxon
countries.  Therefore, the authors wished to draw
the attention of French pediatricians to the haz-
ard of Pb poisoning in young children and to point
out that in cases of gastric or hepatic trouble,
tests for the presence of basophil stippling of
the red blood cells and urinary coproporphyrins
are indicated.
  The case of a 22-mo-old girl who broke a neck-
lace belonging to her mother and swallowed 13 of
the pearls made of a plastic material and coated
with a shiny paint is reported.  The following
                 day, the child developed severe abdominal pain and
                 vomiting; during the night, diarrhea set in and
                 the child passed 5 of the pearls which, however,
                 had lost their brilliancy.  Analysis revealed that
                 the coating of the pearls contained 18.6% Pb.  In-
                 cubation for 5 days of 2 macerated pearls at body
                 temperature raised the Pb content of gastric juice
                 from 14 pg/100 ml to 1.789 mg/100 ml.   Hema-
                 tologic studies in the child showed the absence of
                 anemia but the presence of basophilic stippling.
                 The blood contained 5 ug/100 ml, the urine 80 yg/1.
                   Intravenous administration of 0.5 g CaNa,,
                 gluconate or Ca diaminetetraacetate did not in-
                 crease the urinary Pb excretion but urinary copro-
                 porphyrins rose from practically 0-2000 yg/1.  The
                 child recovered rapidly after daily oral treatment
                 with 1 g CaNa2 gluconate for 5 days.  A bibliog-
                 raphy of 96 references on childhood poisoning by
                 Pb is included.  Signs and symptoms, clinical and
                 laboratory findings, metabolism and treatment of
                 Pb poisoning in children are reviewed.  (96 ref-

                 Childhood poisoning by insecticides, Pb and
                 boric acid is discussed.  As stated by the
                 author, Pb poisoning in infants is not well
                 known in France and seems to be rare; the
                 thought is expressed that this may be due to
                 the fact that it is not always recognized.
                 A recently reported case (Abstract No. 3019)
                 is described.  The clinical picture and treat-
                 ment, based principally on Chisolm's obser-
                 vations, are reviewed.

                 In 1962, 44 children, 1 of whom died, were Pb
                 paint victims in Baltimore, and 3 cases have been
                 already reported in 1963.  Symptoms indicative of
                 Pb poisoning are listed.  As these are general for
                 many child ailments, Pb poisoning must not be ex-
                 cluded, especially in pica cases.
                   The following categories for cases of Pb paint
                 poisoning in children are listed:  (1)  increased
                 Pb absorption (blood Pb >0.05 mg/100 g, positive
                 bone X ray); (2)  Pb poisoning without encephalo-
                 pathy (in addition to I, at least 2 of:  anemia,
                 increased coproporphyrinuria, irritability, con-
                 stipation, vomiting); (3)  Pb encephalopathy (in
                 addition, persistent vomiting, ataxia, convulsions,
                 somnolence, semistupor, or coma).

                 chronic Pb poisoning  is a thing of the past and to
                 the need of recognizing this disease in childhood.

 reflects more accurate diagnosis rather  than in-
 creased incidence.  The epidemiology, diagnosis,
 laboratory  tests and  treatment are briefly stated.
 Control of  Pb poisoning in  children involves the
 concerted efforts of  the parents, the physician,
 public health authorities and social agencies
 responsible for improvement of housing.  It is
 also pointed out that there is no legislation in
 the State of New Jersey controlling the  labelling
 of Pb-containing products.

 Programs developed  in Baltimore and Cleveland for
 the control of Pb poisoning of children  are dis-
 cussed.  Recommended  steps  to wipe out Pb poison-
 ing in Washington are the following:  "1.  Lead
 poisoning should be made a  reportable disease.
 2.  A campaign, under the direction of the Dis-
 trict Health Department and the Medical  Society,
 should be undertaken  to instruct physicians and
 nurses in methods of case finding, in early diag-
 noses and treatment;  and to educate parents con-
 cerning the dangers and prevention of lead poison-
 ing.  3.  ^ow cost  housing  units in good repair
 should be made available for Negro families, es-
 pecially the large  families.  This is the basic
 approach for eradicating plumbism."

Two incidents were reported recently to  the New
York City Poison Control Center.   A 3-1/2-yr-old
boy, suffering from vomiting spells but without a
 history of pica,  was treated for a cold  in 3 dif-
 ferent hospitals.  When the child became comatose
 and had abdominal pains, he was taken to a 4th
hospital where a tentative diagnosis of Pb poison-
 ing with encephalopathy was made.   The child died
 2 days after admission.  Autopsy confirmed the di-
agnosis of Pb poisoning.  There had been broken
 painted plaster in  the premises where the child
had lived for the past 3 yr but the boy had not
been seen eating plaster.   The 2nd incident
concerned a  2-1/2-yr-old boy who had  vomited sever-
al days  prior  to  admission  to  the  hospital  where  he
died of Pb  poisoning after 9 days, in spite of ap-
propriate therapy.

Four incidents were reported one of which was due
 to Pb poisoning.   A 3-1/2-yr-old girl with a his-
 tory of ingestion of painted plaster died of Pb
encephalopathy 19 hr after admission to  the hospi-
tal,  in spite of  treatment with versenate.   The
blood Pb level was 0.46 mg/100 ml; a urine test
 showed a trace of coproporphyrin.

Eight recent  cases of Pb poisoning in children,
aged 2-4.5 yr, are described.  There was a 'his-
tory of  plaster ingestion  in each incident.  All
8 children exhibited increased Pb levels in the
blood; some  showed anemia, abdominal pains or vom-
iting, one developed convulsive seizures and went
into coma.  After treatment with Ca versenate,
often in combination with  Fe, the children became
symptom—free  and could be  discharged from the hos-
pital,   ihe  author states  that up to July 12,
1963, 119 cases of Pb poisoning, 2 of them fatal,
had been reported to the Poison Control Center  in
1963, compared with 82 cases with 2 deaths in the
same period  in 1962.

         15) ,  1963.
The case of a 4-yr-old boy with a history of in-
gestion of Pb-containing paint since the age of 2
or 3 yr  is presented.  Upon admission to the hos-
pital, the Pb level was 80 pg/100 ml in the blood
and 88 ug/24 hr in the urine.  There was increased
bone density  in the metaphyses of the femurs, tib-
ias, fibulas, radiuses, and ulnas.  The child was
treated with CaNa2EDTA and the Pb level in the
blood decreased to 40 ug/100 ml.  After follow-up
examinations, the patient was subjected to several
more courses of EDTA therapy.  Since the family
could not be relocated, the child was sent to
live with an aunt in a good environment.
  In the past 2 yr, the fatality rate in Pb poi-
soning has been reduced markedly primarily be-
cause of intensified case finding techniques that
result in earlier treatment.

        STUDIES OF THE ANEMIA OF LEAD POISONING.
        Pediatrics 31:996-1002 (June), 1963.
Erythrokinetic studies using   Fe and   Cr simul-
taneously, and bone marrow myeloid-crythroid
counts were performed on 7 children,  aged 2-10 yr,
who had suffered from Pb poisoning for a period of
a few months  to 8 yr.  All children showed a raicro-
cytic, hypochromic anemia.  Three patients with
relatively short histories of Pb intoxication
demonstrated  a pattern characteristic of a hemo-
lytic process.  Three other ones with more pro-
longed histories displayed erythrokinetic patterns
indicating erythroid hypoplasia.  One child showed
a normal pattern.  These results of the study in-
dicate that  several mechanisms exist for the pro-
duction of Pb anemia, depending on the duration of
intoxication.  Furthermore, Pb involves the blood
and bone marrow in several ways.

Data on the 6-aminolevulinic acid dehydrase
(ALA-D) activity and hematologic information was
tabulated for 16 normal subjects, 9 children with
Fe-deficiency anemia and 11 children with Pb poi-
soning.  The activity of ALA-D, the enzyme neces-
oary for conversion of ALA to porphobilinogen  was
significantly lower in Pb poisoning than in normal
or Fe-deficient subjects.  The ALA-D deficit could
be reversed by preactivating the incubation mix-
tures with glutathione; however, glutathione pre-
incubation did not augment in vitro porphyrin
production from ALA.  This seems to indicate a de-
fect in the biosynthetic pathway for heme in the
sequence beyond porphobilinogen.

Histologic, chemical and clinical findings on a
group of 23 children, aged 24-49 mo, all of whom
succumbed to Pb poisoning during the warmer months
of the year, were reported.  The clinical course
was similar in all these children; weeks of an-
orexia, irritability and periodic vomiting were
followed by depressed consciousness and/or convul-
sions.  The interval between the onset of clini-
cally apparent encephalopathy and death was gener-
ally <72 hr.  The concentration of Pb in the brain
was measured in 6 cases.  Highest levels were
found in the hippocampal and frontal cortices,
lowest levels in  the occipital white matter and
pons (2.712, 2.513; 1.210 and 1.329 ug/100 g wet
tissue, respectively).  The brains were swollen,
showing a mean increase of 17.7% in weight.  Char-
acteristic histopathologic alterations were seen
most consistently in the cerebrum and cerebellum.
They suggested that the initial effects of Pb poi-
soning were selectively exerted upon the intrinsic
blood vessels of  small  caliber where they  caused
increased permeability, focal necrosis, occlusion
and the transudation of plasma fluid into the
perivascular, interstitial and subpial spaces.

Since no information has yet been published in
                  Venezuela on Pb  poisoning in infants,  this  paper
                  was  planned to  draw attention to these hazards.
                  The  etiology, pathology,  manifestations of  acute
                  and  chronic Pb  poisoning, diagnosis and treatment
                  are  reviewed.   Case reports  of 4 infants who had
                  been accidentally poisoned by inhalation of Pb
                  fumes are given  in detail.
                    The 1st case  occurred in 1954 in a 9-mo-old
                  child who was admitted to the hospital with a se-
                  vere digestive  syndrome and  manifestations  of the
                  central  nervous  system.   The parents were engaged
                  in repairing storage batteries in their home and
                  both had been suffering from chronic Pb poisoning
                  for  many years.
                    In 1962, the mother of  the patient described
                  above came to the hospital with 3 children  who
                  displayed symptoms comparable to those of 3 sons
                  who  had  died within the past 8 yr,  the last one
                  only 1 mo previously.   They  all showed a moderate
                  hypochromic anemia.   The  level of Pb in blood ex-
                  ceeded markedly  the threshold limit of 0.050
                  mg/100 ml blood,  urinary  Pb  excretion ranged from
                  0.060-0.182 mg/1 urine before and from 0.430-
                  1.800 after administration of CaNa^EDTA. De-
                  termination for  porphyrins was discussed, but
                  was  not  carried  out.

                  A 2-1/2-yr-old Negro boy  was admitted because of
                  vomiting,  anorexia,  and lethargy.  On examination,
                  he appeared chronically ill, poorly nourished, and
                  comatose.   ne was given iv drip of saline and dex-
                  trose,   riematology showed 6.7 g/100 ml hemoglobin,
                  hypochromic and  microcytic red cells with moderate
                  anisocytosis and poikilocytosis.   When taken to
                  the  ward,  the boy was in  extremis and died  shortly
                  afterwards (1 hr 40 min after arrival in the emer-
                  gency room).  The family  history did not help in
                  establishing a  diagnosis. he was a plump baby
                  until 4  mo of age when he began to lose weight  in
                  spite of a good  appetite; he was seen in the Out-
                  patient  Department 11 mo  before admission because
                  of a viral infection and  was thought to have nu-
                  tritional anemia but did  not return for a hemo-
                  gram. The final pathologic  diagnoses upon  autopsy
                  were: (1)  acute  Pb encephalopathy,  (2) intersti-
                  tial pneumonitis, (3)  anemia, (4) hepatomegaly,
                  and  (5)  intranuclear inclusions in kidney and
                  liver.   A sample of brain tissue contained  0.256
                  mg Pb/100 g.  X rays of the  chest supported the
                  diagnosis of Pb  poisoning by the presence of lines
                  of increased density at the  proximal ends of the
                  humeri.

 acute symptoms,  the  6th  child  survived  for  39  days.
 The  clinical picture was  characterized  by vomiting,
 headache, drowsiness,  stupor or coma, papilledema
 and  alterations  in pupillary size  and reaction.
 Pathologically,  considerable swelling of the brain
 was  evident in the 5 acute  cases;  1  of  these
 showed petechial hemorrhages in the  cortex  of  1
 occipital lobe.  Microscopically,  4  showed  partial
 loss of myelin and an  astrocytic reaccion in the
 white matter.  Three showed perivascular edema and
 petechial hemorrhages.  The chronic  case revealed
 extensive tissue destruction with  cavity forma-
 tion,  associated with  marked astrocytic and micro-
 glial reaction,  thickening  of  the  veins with cell-
 ular disorganization of  their  walls, and very  re-
 cent thrombosis  of dural  sinuses.  The  pathologic
 appearance suggested to  the authors  that vascular
 damage is a major factor  in the pathogenesis of
 the  cerebral disorder.   (26 references)

        AND LABORATORY  OBSERVATIONS.   American
        Journal of Diseases of Children 105:609-
        16 (June),  1963,
 Four groups of  10 children each were studied.   The
 patients in Group 1  had been diagnosed 5 or more
 years  prior to  this   study as having Pb encephalo-
 pathy; all children demonstrated (1)  excessive Pb
 absorption as indicated by a history of pica and
 a Pb level in the blood of =0.06 mg/100 g,   (2)
 signs  of involvement of the central nervous  sys-
 tem,  and (3)  a  protein  level in the cerebrospinal
 fluid  >40 mg/100 ml.   Group 2  consisted of  chil-
 dren who had pica 5   or  more years prior to   this
 study, and had  absorbed an excessive amount
 of Pb  as indicated by Pb  levels in the blood of
*0.06 mg/lOO g,  but  who had not displayed effects
on the central  nervous  system  and  changes in the
 cerebrospinal fluid.   Group 3  consisted of  chil-
 dren suspected  of possible Pb  poisoning because
 of a distinct history of  pica,  but with a Pb con-
 centration in the blood <0.06  mg/100 g and  with a
 urinary content of Pb also within the normal
 range  (0.02 mg/1).   Group 4 served as controls.
The age of the  children at the time of the  origi-
nal  illness was 9-40 mo and 6  yr 2 mo to 11 yr 3
mo at  the follow-up  examination.
  Except for the presence of seizures or other
 neurologic sequelae  among the  children with prior
Pb encephalopathy,  none of the children in   this
 study  showed signs or symptoms suggestive  of or-
 ganic, nonbehavioral residuals.  The incidence of
 recurrent convulsions was 40%  among those with Pb
 encephalopathy  while an additional 20% had  other
manifestations  of neurologic damage,  presumably
 due  to Pb.  Abnormal electroencephalographic pat-
 terns were found twice  as often in the patients
with Pb encephalopathy  as in other groups.   Nei-
 ther pica nor Pb  absorption without encephalopathy
 increased the incidence of these abnormalities
over the 30% incidence  observed in the controls.
The incidence of  pica among the controls was 20%.
No abnormalities  were observed on follow-up X-ray
 examination except faint scars at the sites  of the
 original "Pb lines"  in  one third of the children
who had previously had Pb encephalopathy or ab-
sorption.  Since  the blood level of Pb was within
elevated range in 3 children with prior Pb poison-
ing and in 1 child previously diagnosed as having
pica without excessive Pb absorption, children
with prior plumbism or with pica must be observed
repeatedly during follow-up.
  It is concluded that Pb poisoning causes signi-
ficant physical and laboratory sequelae only if it
is associated with encephalopathy.  Neither uncom-
plicated Pb poisoning nor pica without Pb intoxi-
cation resulted in physical or laboratory abnor-
malities 5 yr later.

        (July),  1963.
A striking epidemic of apparently Pb-induced renal
disease in Australia was the initial stimulus for
the Massachusetts investigation of 165 persons who
had been intoxicated with Pb in childhood >20 yr
ago and who had shown unequivocal evidence of Pb
intoxication but had survived the acute episode.
Admission to this study group required that any 2
of the following  3 diagnostic criteria be ful-
filled:  (1) a definite history of pica for Pb-
containing material (usually paint)  or the use of
Pb nipple shields; (2) X ray evidence of typical
Pb-induced skeletal alterations;  (3) clinical evi-
dence of symptoms and signs characteristic of
childhood Pb Intoxication affecting 2 or more or-
gan systems.  Of the 165 persons, it was possible
to obtain information on the health status of 139
(84%).   Ten of these had died after the initial
intoxication (3 due to confirmed  Pb poisoning at
age 2;  1 at 23 from chronic renal disease of un-
certain etiology; the rest from accidents  or other
unrelated causes).  Screening tests of renal func-
tion in 42 subjects of the group  yielded no con-
vincing evidence of chronic renal impairment.  The
difference between sequelae of plumbism in Massa-
chusetts and Australia and possible causes for
this variation were discussed. Based on the Mas-
sachusetts results it was concluded that it is not
likely that body burdens of Pb associated  with
urban air contamination will induce chronic renal
disease in persons so exposed.

        POISONING SCREENING TEST  STUDY.   Washing-
        ton, D.C., July-Aug., 1963,  6 pp.
A pilot study to determine the efficacy of various
screening tests  for Pb poisoning  was carried out
on 966 Ohio children,  aged 18-36  mo, from neigh-
borhoods suspected of having a high incidence of
Pb poisoning.  Pb levels in blood and urine and
urinary ALA and coproporphyrin (CP)  were deter-
mined, and the upper limits of normal for these
4 biochemical tests were set as follows:  blood
Pb, 0.06 mg/100 g of blood; urinary Pb,  0.08
mg/1 of urine; urinary CP, 50 yg/100 ml of urine;
urinary ALA, 0.6 mg/100 ml of urine.  Of the 966
children in the survey, 866 had all 4 tests.  Of
these,  726 were negative to all tests and  only 1
was positive by all tests.  Of the 42 children
with positive blood Pb, only 3 reacted positively

the concentrations of ALA, Pb and CP in a casual
urine specimen  cannot be relied on for screening
purposes to predict blood Pb levels.  The most
workable technique appears to be analysis of the
blood for Pb.

The process by which the Pb contained in Pb nip-
ple protectors is first absorbed by the mother
and then ingested by the infant, was studied.
The author describes in great detail a method of
determination for Pb, using dithizone.  By means
of this technique, the Pb content was estimated
in cow's and human milk to be 50-160 (mean 90)
and 20-60 iJg/1, respectively.  Subsequently, the
capacity of both cow's and human milk to react
with the Pb in the nipple shields was studied by
immersing the shields at 37° C in various amounts
of milk, for various periods of time.  It was
found that human milk dissolves a greater amount
of Pb than does cow's milk.  Since the estimate
indicated daily deposition of Pb on the breast of
>1 mg, considerable amounts could reach the moth-
er's milk by absorption through the skin.  There-
fore, Pb nipple protectors are potentially harm-
ful.  The immediate discontinuance of their use
was strongly recommended.

        June),  1963.
Following a review of the literature, a case of Pb
poisoning In a 15-yr-old workman in a storage
battery factory for ^1-1/2 yr is described.  He
was admitted to the Pediatric Ward with intermit-
tent abdominal  cramps and generalized convulsive
seizures.  The  main signs and symptoms were typi-
cal of Pb poisoning: pallor, abdominal cramps,
vomiting, mental confusion, restlessness and irri-
tability, generalized convulsions, Pb line, hypo-
chromic microcytic anemia with stippled erythro-
cytes, coproporphyrinuria, positive skin test with
Na sulfide and  increased density at the epiphysis
of long bones upon X ray.  The boy was treated
with BAL and other supportive measures, out there
was no improvement and he died 3 days after ad-
mission.
  The author stresses the importance in correct
diagnosis of establishing the source of Pb, par-
ticularly in children, together with the classical
signs.  The use of CaEDTA is mentioned as being
highly effective; formerly it was considered to
have no side effects; however, deaths from renal
failure because of improper use have been re-
ported.  Where  EDTA is not available, BAL may be
used.  The treatment of Pb encephalopathy with        3Q42
urea, hypothermia, and surgical decompression is
also mentioned.  (From author's English summary;

                 The causes of Pb poisoning in children living in
                 large cities are reviewed and the program of the
                 Chicago Board of Health for the prevention of
                 such poisonings is discussed.  Since in spite of
                 the measures taken new cases continue to occur,
                 Pb poisoning has been made a reportable disease
                 this year.  When a large number of cases occur,
                 a door-to-door campaign, inspecting premises and
                 correcting conditions, is undertaken.  While Pb
                 poisoning has been successfully prevented in most
                 areas of Chicago, it still needs to be eliminated
                 in areas where neglect and ignorance prevail.

                         1964.
                 In this "leading article," it is pointed out that
                 childhood Hg poisoning has virtually disappeared
                 since the principal cause of it, calomel, has
                 been withdrawn; also, that although the means of
                 prevention of Pb poisoning are clear, though not
                 so easy to accomplish, Pb poisoning is still
                 widespread.  An important part in bringing cases
                 to light has been the introduction of readily
                 available methods of estimating the level of Pb
                 in the blood, although in some cases the blood
                 levels may not be raised, and the height of the
                 level (an upper limit of 36 pg/100 ml recently
                 proposed by A.A. Moncrieff) does not necessarily
                 correspond to the severity of the condition.
                   Recent studies of the incidence, cause and di-
                 agnosis of childhood plumb ism are discussed (Mon-
                 crieff, et al; R.C. Griggs, et al).  Emphasis is
                 laid on early diagnosis which is difficult be-
                 cause of frequently bizarre onset of illness, and
                 can no longer depend upon the former classical
                 signs of punctate basophilia, Pb lines in gums,
                 bands of increased density of bones, and others,
                 for by the time these appear, irreparable damage
                 may have been done.  A history of pica is always
                 suggestive and flaking paint inside old homes is
                 the commonest cause of Pb poisoning.  The impor-
                 tance of notifying local public health authori-
                 ties is stressed, so that steps can be taken to
                 remove the cause and ensure proper care of af-
                 fected children.
                   Although treatment of choice now is EDTA, ei-
                 ther intramuscularly or intraveneously, Mon-
                 crieff, et al favored penicillamine which could
                 be administered orally.  B.F. Andrews  (1961)
                 warned, however, that use of EDTA may cause kid-
                 uey damage, and B.D. Dinman  (1962) pointed out a
                 disadvantage of both chelating agents in that
                 there is no evidence that their action extends to
                 bone where most of the Pb is stored.  The article
                 closes by emphasizing again  that prevention must
                 be  the first aim.

 A case  of Pb  poisoning  in a  4.5-yr-old  child,  re-
 ported  to the Hampstead Health Department,  led
 to an appeal  to  the Home Office  for  a ban on  the
 sale  of plastic  toys with a  high Pb  content.
 Some  of the child's toys contained Pb at concen-
 trations of 258-1970 ppm, and showed signs  of
 having  been chewed on.  Other plastic toys  sold
 in local shops had comparable Pb levels.  Accord-
 ing to  the public analyst, these toys constitute
 a real  source of danger if chewed or sucked by a
 child or even an adult.

         Lancet 1:867-8  (Apr. 18), 1964.
 The importance of prompt treatment with CaNa2EDTA
 in children with Pb poisoning is emphasized.   The
 diagnosis of  Pb  poisoning should be  considered in
 children with unexplained anemia, convulsions
 raised  intracranial pressure, renal  glycosuria
 and amino-aciduria, and abdominal pain, especially
 during  the 2nd and 3rd  yr of life.   An inquiry
 about pica should be a  routine part  of history-
 taking.  The  sources of Pb absorption and essen-
 tial  diagnostic  factors are presented.  Among
 these,  the blood-Pb values are discussed in
 greater detail on the basis  of the report by A.A.
 Moncrieff et  al  at Great Ormond  Street, who found
 Pb  in the blood  of all but 2 of  80 normal chil-
 dren  to be <36 ug/100 ml, although the upper lim-
 it  has  been usually regarded as  50-60 yg/100 ml,
 allowing for  an  overlap between  the  values  in
 normal  and poisoned children.  Moncrieff's  accep-
 tance of the  36  pg as the upper  limit, and  the
 finding of abnormal blood-Pb in  45%  of 122  chil-
 dren with severe mental subnormality or behavior
 disorders, also  in 30% of children with apparent
 encephalitis, and in 54% of children with abdomi-
 nal pain, pica,  vomiting, anemia, or irritabili-
 ty, caused the Editor to raise the question
 whether  all these children were  suffering from Pb
 poisoning and to state that a blood-Pb of 40-50
 Pg/100  ml may mean no more than  that the patient
 has pica because of mental abnormality due  to  a
 cause other than Pb poisoning.  He points out  that
 the introduction of the determination of blood-Pb,
 and the  easy  access to a test requiring only a
 single  specimen  of blood,  led to increased  fre-
 quency  of diagnosis of undoubted Pb  poisoning
 which would have been difficult  to recognize by
 the usual method.  He recommends that other cen-
 ters also provide facilities for this test.

Eight cases of Pb poisoning were reported, 7 in
children aged 2.5-10 yr and 1 in an 18-yr-old boy.
There were 4 cases of pica among the group.  The
manifestations varied from headaches, colic, ane-
mia, paresthesia, urinary disturbance, to paralysis
and encephalopathy.  Coproporphyrinuria was posi-
tive in all cases.  A count of stippled erythro-
cytes was made in 5 patients, with positive re-
sults being found in 3.  Determination of the Pb
level in blood in 6 cases revealed a Pb content
exceeding 60 yg% (up to 140 yg%) in 5 of them.
All patients were treated with CaNa2EDTA at a dose
of 75 mg/kg body weight/day, and in 1 case iv in-
jections of Ca gluconate were also given.  In a
5-yr-old girl, symptoms of endocranial hyper-
tension improved by iv administration of urea and
corticoadrenal hormones.
  In his discussion, the author points to the vari-
able symptomatology in these cases, as well as to
the fact that childhood poisoning may occur by in-
halation as well as by ingestion.  Aside from the
pica, one case of illness was incurred in a home
printing shop (10-yr-old) ; one (8-yr-old) worked
with his father and brother in a storage-oattery
factory; and the 3rd of the inhalation cases (18-
yr-old) lived next to a workshop the chimney ef-
fluents of which traversed the common wall.

        44-53 (June), 1964.
ihe case reported is that of a boy with pica who
became an idiot following the ingestion of garden
soil contaminated by Pb.  This contamination was
thought to be due to the burial of old paint.  A
random sample of the soil was found by local public
health authorities to contain 0.22% Pb.  The boy
was the only patient among °"1000 consecutive
admissions of idiot and imbecile children to the
Fountain Hospital from 1950 through 1962, ,*hose
mental defect could be reasonably attributed to Pb
poisoning.   The first evidence of abnormality was
observed at the age of 2.5 yr when the child
started to indulge in persistent rocking and head
banging at night.  At 2 yr 11 mo he developed a
pyrexial illness with diarrhea and vomiting.
When he did not respond to antibiotic therapy, he
was transferred, after 1 mo, to the Hospital for
Sick Children, Great Ormond Street.  At this time,
his Hb was 79%,  he showed stippled erythrocytes
and the cerebrospinal fluid contained 150 mg pro-
teins/100 ml.  Pb poisoning was suspected and
confirmed by a Pb content of 35 ug/100 ml urine
and 117 yg/100 ml blood.  tie was treated with
EDTA (0.5 g/12 hr) by iv drip, in 2 courses of 3
days each,   although the Pb concentration in the
blood fell to 7-21 pg/100 ml, he remained grossly
mentally retarded with spastic limbs and increased
tendon jerks.  At 4.5 yr he was functioning at the
level of a 9-mo-old normal infant.  At the time of
this publication he was 6 yr old and not improved.

childhood in Great Britain, where it is stated to
be rarely reported, 36 cases are tabulated as to
available data, including author, source of Pb,
age at time of acute illness, presence of enceph-
alopathy, and follow-up findings.  The signifi-
cance of pica in the genesis of Pb intoxication
is pointed out.  In discussing sequelae of Pb poi-
soning in children, the author states that such
severe impairments as in the above reported case
are unusual, but that less obvious sequelae may
often be missed, thus leaving the impression that
Pb poisoning in childhood is more innocuous in
regard to subsequent mental development than is
actually the case.

Pb poisoning as the cause of mental disturbance
in children is discussed.  Examples are quoted of
children contracting Pb poisoning by sucking Pb-
painted toys, playing with Pb-containing putty,
handling Pb-containing sprays, etc.  Although in
some cases permanent damage may remain, all symp-
toms often disappear when the source of Pb is
removed.  High credit is given to London's Great
Ormond Street Hospital for Sick Children which
has set it as its goal to diagnose and possibly
cure mental disease due to excessive absorption
of Pb and to explore whether metals other than
Pb also cause mental disorders in children.

I.  The diagnosis of Pb intoxication may be sus-
pected, when one or more  of the following crite-
ria are present; among such criteria, the authors
consider a history of pica, X-ray evidence of
radiopaque material in the gastrointestinal
tract, and of "Pb" lines  at the metaphyseal ends
of the long bones, to be suspicious evidence; el-
evated Pb content of blood or urine to be possibly
equivocal; and the signs  and symptoms of intoxi-
cation of the central nervous system, vomiting and
other gastrointestinal disturbances, reducing sub-
dtance in the urine, anemia, basophilic stippling
of red blood cells, and the positive test for cop-
roporphyrin III, as strongly indicative.  Kehoe
is cited as regarding the last-named test as the
first sign of Pb poisoning.
  From 1959 through 1961, of the total of 9,853
cases of accidental poisoning reported to the
Chicago Board of Health,  429, or 4.7%, were due  to
exposure to Pb, of which  67 were fatal (79% of
total deaths).  Pica, with positive history of the
ingestion of Pb, was found in 59.7% of the cases;
in 2.6% of these, the ingestion of Pb was not
proved.  The highest incidence and the highest
rate of mortality occurred in children 12 to 36
mo old.  Peak periods of  occurrence v;re June
through September.  However, in December 1959, 17
cases of poisoning resulted from the burning of
storage batteries, and the inhalatic.i ->* Pb fumes.
                 Neither sex nor race seemed to be a predisposing
                 factor.  Since the greatest number of cases came
                 from the nonwhite slum areas,  the environment,  in
                 addition to age,  is significant.
                   II.  A survey was made, by the Chicago iioard of
                 health, of 1,500 children residing in 3 different
                 Chicago areas, to evaluate the use of urinary coo-
                 roporphyrin (CP)  determinations as a screening
                 test for case finding in asymptomatic children.
                 The first area in which a high incidence of Pb
                 poisoning was known to exist,  had buildings >50
                 yr of age and in poor repair;  in the 2nd and 3rd
                 areas, the buildings were relatively new and no
                 cases of Pb poisoning had been reported during
                 the past 3 yr.  However, the 3rd area was close
                 to a blast furnace, and trie concentration of Pb
                 in the air in the immediate vicinity was found to
                 be ^10 tines as high as it was in otner areas of
                 the city.
                   The parents of children, aged 1-5 yr, and the
                 physicians in these areas were informed of the
                 program.  The public health nurse was instructed
                 to collect a minimum of 1 oz of freshly voided
                 urine and to take this to the Board of Health
                 laboratory within 4 hr.  Urinary CP was determined
                 by the methods of Benson and Chisholm.
                   In Area 1, 91 children (18% of these studies)
                 were found to have positive urinary CP.  Of these,
                 44% revealed clinical and/or laboratory evidence
                 compatible with the diagnosis of Pb poisoning
                 (increased blood Pb, X-ray evidence of Pb deposits
                 in the long bones or in the gastrointestinal
                 tract.)  Area 2 yielded only 14 or 2.8% patients
                 with positive urinary CP; only 3 exhibited evi-
                 dence of significant exposure to Pb.  In the 3rd
                 area, 16 or 3.2% patients showed positive urinary
                 CP, only 1 of whom had a borderline blood Pb lev-
                 el.  (Abstracts prepared by R.A. ^ehoe, M.D.)

                 to exist between certain of the findings of this
                 investigation and the conclusions arrived at.
                 Thus reference is made to elevated levels of the
                 concentration of Pb in the blood, and yet the
                 tabulated data demonstrate that the concentration
                 of Pb in the blood of the group of children that
                 was most suspected of having abnormal quantities
                 of Pb, ranged from 5-20 pg/100 ml.  This is the
                 low segment of the normal range which extends
                 from 5-50 Mg/100 ml blood.  Nothing within this
                 range can be regarded as abnormal, nor are such
                 levels compatible with the induction of abnormal
                 densities in the metaphyses of the long bones.
                 One queries therefore whether analytical or ra-
                 diologic technique was at fault.  By the same to-
                 ken such analytical findings are incompatible
                 with clinical Pb intoxication.  It seems likely
                 that the method of analyzing the blood for Pb
                 yielded unduly low results, but the uncertainty
                 in this matter is more than a little disconcert-
                 ing.)

BIOLOGICAL ASPECTS OF LEAD

 observed  in Pb poisoning  in children, par-
 ticularly the persistent  severe colicky pain is
 not  a manifestation of Pb poisoning in children.
 Examination of artificial pearls revealed that
 Pb carbonate, Pb phosphate, Pb arsenate and a Bi
 salt are  used in the manufacture of such beads;
 Pb arsenate was present in 3 out of 5 beads
 tested.   The author believes that the case was
 essentially one of As poisoning even though Pb
 was  found present.  In 1200 cases of Pb poison-
 ing  in  children reported  to the dew York City
 Department of Health Poison Control Center, severe
 colicky pains and foul diarrhea were not among
 the  signs and symptoms mentioned.  As an obvious
 conclusion from these findings the author advises
 that beads be kept away from young children, be-
 cause they may be coated with Pb compounds.  The
 question  is raised also why the child was not
 treated with EDTA, as this case was originally
 diagnosed as Pb intoxication.

 Information collected during 1952 through 1958
lias  shown that ^8-9 Cleveland children were hos-
 pitalized per year for Pb poisoning, with a mor-
 tality of 30%; 85% of these cases were seen in
 the  summer months; the majority came from the
 so-called "Pb belt" in Cleveland, an area char-
 acterized by old and generally substandard hous-
 ing.  The present study was carried out during
 the  summer months of 1959 and 1960 in 4 census
 tracts within the "Pb belt"; 3 of the areas had
 old  housing and one was a new housing project.
The  door-to-door survey included 994 children be-
 tween the ages of 12 and 60 mo.  In a question-
naire, the birth date of the child, condition of
 the  home, history of previous poisoning and of any
pica was listed.  For purposes of this study, a
 child was classified as having Pb intoxication
when any 3 of the following 6 factors were found;
history of pica for paint, dirt or plaster; ab-
normal urine (levels of,  or higher: 0.08 mg Pb or
 0.200 mg  CP III/l, 0.30 uM ALA/ml; Pb in the
 blood  iP.06 mg%; Hb 
-------
sive overdose of dimercaprol (BAL) which caused
nausea, vomiting, excessive salivation, abdominal
and chest pains, flushing of the face, muscular
cramps and burning sensation of the skin.
  The authors warn against the  use of  BAL and also
remind physicians that EDTA has no accepted pedi-
atric use.  Recent reports recommend the use of
D-penicillamine but it is not an officially recog-
nized drug for Pb poisoning.  During 1963 to Sept
25, 223 cases of Pb poisoning, of which 5 termi-
nated fatally, were reported in New York City, and
156 with 6 fatalities during the same time the
year before.  All these cases occurred in children
<6 yr of age and chiefly in the ages between 2-4
yr.

Many cases of Pb poisoning with blood Pb levels
considerably above the presumed standard for posi-
tive diagnosis of 0.06 mg/100 ml have recently
been labeled by the reporting hospitals as "pos-
sible" Pb poisonings.  Six such incidents in chil-
dren, aged 1.5-7.5 yr, with blood Pb levels rang-
ing from 0.06-0.32 mg/100 ml, are described.  The
authors recommend that treatment should not be
delayed in cases with a positive history of pica
and blood Pb levels of 0.06 mg/100 ml and over.
A possible new physical sign in the early diagno-
sis of Pb poisoning, that is a greyish stippling
of Pb pigment that is circumferential around the
optical disk, has been described by Sonkin in oc-
cupational Pb poisoning.   Visualized through the
ophthalmoscope, Pb particles appear as glistening,
discrete grey pigment in the retinal area around
the optic disk.  The authors point out that they
do not know whether or not such changes may occur
in children suffering from Pb poisoning, but they
consider them worth looking for.

An investigation was carried out to elucidate
whether mental retardation in some children may
be caused by increased Pb absorption.  The criti-
cal level for Pb, to reach its full toxic effect,
is ""80 vg Pb/100 g whole blood.  The clinical pic-
ture in children is different from that of adults.
No case of even the mildest type of poisoning has
been induced in children when the Pb level was
<0.04 mg/100 g of whole blood.  An increased con-
^ent of ALA in the urine is regarded as an early
 ign of poisoning.  At Great Ormond Street Hospi-
^al for Sick Children, there were 30 cases of Pb
poisoning and 65 cases of mentally retarded chil-
dren with high Pb concentrations in the blood and
an increased content of urinary ALA.  The author
never found children with Pb poisoning whose Pb
level in the blood was <0.045 mg/100 g of whole
blood.  Normal children, mentally defective chil-
dren, children suffering from encephalitis and
                 children with Pb poisoning were examined.  The
                 following data were found in 200 normal and 100
                 mentally defective children, respectively:  Pb in
                 whole blood, 0.014-0.030 and 0.040-0.080 mg/100
                 ml; pyruvic acid in blood, 1 and 1.4 mg/100 ml;
                 ALA, 0.20-0.26 and 0.38 mg/100 ml urine.  ihe men-
                 tally defective children who all had neurological
                 symptoms improved greatly by treatment with a
                 chelating agent.  Half of the children with ence-
                 phalitis had an average Pb concentration in the
                 blood of 0.050 mg/100 ml and in some, pyruvate
                 was 1.50 mg/100 ml blood.  Neither ALA nor pyr-
                 uvate levels were pathologically raised at Pb
                 concentrations of <0.035 mg/100 ml blood.  Oral
                 administration of penicillamine shortened the
                 metabolic disturbances caused by Pb and contrib-
                 uted to the intellectual improvement of the chil-
                 dren.

                 the cerebrospinal fluid and lactic dehydrogenase
                 (LDH) activities were studied in 106 children
                 with neurologic disorders, including 1 case of Pb
                 encephalitis, and 41 neurologically normal chil-
                 dren, ranging in age from 1 wk-11 yr.  In the
                 control group, GOT activity ranged from 2.0-
                 15.0, mean 5.9, and LDH activity from 1.1-40.0,
                 mean 14.3, units/ml/min.  In the 2.5-yr-old child,
                 suffering from Pb encephalopathy, GOT activity was
                 6.7 and LDH activity 12.3 units/ml/min.  There was
                 no  correlation between GOT and LDH changes.
                   The authors consider that a study of these en-

                 followed for 17 mo-8 yr and 3 mo.  In addition, a
                 successful treatment of intrauterine Pb poisoning
                 is  reported for the first time.  Pica for paint or
                 soil was the antecedent in 4 children, aged 20 mo-
                 3 yr.  Subsequent analysis by health authorities
                 revealed a Pb content of 26.6% in the paint in the
                 home of the 20-mo-old boy who had been admitted
                 to  the hospital with acute hemiplegia followed by
                 intractable seizures while a 2-yr-old had persis-
                 tent strabismus.  The 4 other children  (aged 1.5-fa
                 yr) came from a family which had used old battery
                 cases as fuel in the living room stove.  One of
                 these children, a 3-yr-old boy, died of acute en-
                 cephalopathy with convulsions despite treatment
                 with CaNa2EDTA.  tiis 18-no-old brother, at follow-

abnormal asymmetry, asynchrony and slow mental
development.  The 27-yr-old mother was 8 mo preg-
nant when her blood was found to contain 0.24 mg
Pb/100 ml.  She was treated iv with EDTA for 7
days.  The child appeared normal at birth and at
follow-up, 4 yr and 2 mo later, his electroen-
cephalogram, mental development and neurological
functions were normal.
  In conclusion, the author points out that a his-
tory of pica should alert the physician to the
possible diagnosis of Pb poisoning; that the par-
unts should always be questioned concerning pica,
and that Pb poisoning in pregnancy should be
treated promptly.

        POISONING IN CHILDREN.  Letters to the
        Editor.  i,ancet 1:941 (Apr. 25), 1964.
The author refers to the leading article on "Lead
Poisoning in Children" in the April 18 issue of
this journal.  He points out that more emphasis
should be laid on estimation of urinary Pb since
levels >0.10 mg/1 indicate trouble.  Another sen-
sitive and accurate procedure is the examination
of blood films, stained with methylene blue.
Marsh describes the case of a 3-yr-old child, not
suspected of Pb poisoning, whose blood-film
showed some unusual features.  Further tests, in-
cluding the demonstration of lines of increased
density at the growing ends of bone, showed that
the child had advanced Pb poisoning.  Finally, he
states:  "Lead encephalopathy can occur without
other classical signs of Pb poisoning, as I showed
in the 1939-45 war for workers in leaded petrol."

Since 1950, 804 cases and 76 deaths of Pb poison-
ing in children have occurred in Philadelphia.
The 1- to 3-yr age group accounted for 82% of the
cases and 1/3 of these occurred in the 19-24 mo
of age.  The lower socioeconomic group provided
5 times as many cases as all other groups togeth-
er, with mortality rate in this group of M.0%.
The highest incidence of Pb poisoning is from May
through October.  Control of Pb poisoning requires
legislation in combination with educational mea-
sures.

        DREN.   Archives of Disease in Childhood
        39:1-13 (Feb.), 1964.
The present study was carried out primarily to see
whether any children referred to the hospital for
the investigation of mental retardation had Pb
poisoning.   As a preliminary, the normal range of
Pb in the blood of children was determined.
eighty children, aged 4 mo-14.25 yr, who were
neither mentally retarded nor had a history of
pica,  were found to have Pb levels in the blood
of 536 yg/100 ml, with the exception of 2 chil-
dren who had slightly higher levels.  Thus, 36
yg/100 mg blood was taken as the upper limit of
 normal.   Among  122  children,  aged  6  mo-14  yr, who
 were  mentally retarded,  or  had  severe  behavior
 disorders,  45%  had  Pb  concentrations in  the blood
 >36 yg.   Among  40 children, aged 2 mo-12 yr, with
 a  preliminary diagnosis  of  encephalitis, 30% had
 Pb levels >36 yg/100 ml  blood.  Among  52 children
 with  severe anemia, pica or vomiting,  54%  had Pb
 levels  >36  ug/100 ml blood.   Abnormally  high pyr-
 uvate levels in the blood (normal  upper  limit
 1.4 mg/100  ml)  were found in  20 of 36  children
 with  Pb  levels  >36  yg/100 ml  blood.  A group of
 20 children, 13 boys and  7 girls,  age  9  mo-5 yr,
 all with  Pb poisoning, were studied  in detail.
 Twelve came from families living in  unfavorable
 conditions, 3 had access  to putty  containing red
 Pb, 4 or  more had been eating old  paint  chippings,
 2 had received home-^rown vegetables produced on
 a soil containing Pb battery casings.  One child
 was retarded and another was psychotic.  Findings
 concerning blood Pb, punctate basophils, copropor-
 phyrinuria and radiological evidence were tabu-
 lated.  ,'jiemia was common in all, but none showed
 aminoaciduria,  glycosuria or a Pb  line on the gum
 margins.  All these patients were  treated with
 oral penicillamine  (150,  300 and 450 mg  twice
 daily for children aged up to 5 yr,  5-10 yr and
 >10 yr,  respectively).  Four patients  in addition
 received  1 or 2 courses of intramuscular CaNa2EDTA
 and 1 received 2 courses of iv EDTA  (75 mg/kg body
 weight/day).  The effects of the various treat-
 ments in  some children are described.
  The records of The Hospital for Sick Children
 showed that from 1951-1960,  12 children had been
 diagnosed as having Pb poisoning.  Since 1961,
 when the  estimation of blood Pb became freely
 available, it was apparent that the  incidence of
 diagnosed cases  had risen sharply  (even by ac-
 cepting the classical upper level of normal of
 50-uO yg/100 ml blood) .  The diagnosis of estab-
 lished Pb poisoning usually presents no problem,
 but early Pb poisoning may mimic so many diseases
 that the  diagnosis is difficult.  The decision to
 treat or  not to treat borderline cases depends on
 consideration of the whole problem.  In  this  re-
 spect, the finding of a raised pyruvate level is
 considered as further evidence particularly when
 the increase of blood Pb has been "oorderline."
 (However, the pyruvate level may be normal and the
blood Pb very high.)  Measures in the treatment of
Pb poisoning are discussed and in the Appendix
methods  for the estimation of Pb in blood and
urine are described.  The authors point out that
Pb levels in blood between 40 and 60 yg/100 ml
 should always be carefully considered in the light
 of other  clinical findings,  particularly when the
 child is  <5 yr  of age.   (29  references)

The clearly presented and thorough  account of the
 response of the organism to nutritional distur-
 uances is based on extensive experience gained in
animal experiments and in clinical  observations,
 including X-ray  and histologic examination (when-
ever the  latter  were possible) of some 800 chil-
 dren,  aged from birth to 14 yr, hospitalized in

  In the economy of the body of the young animal,
when depletion of nutrients as caused by disease
of all types becomes serious enough, the bones
take up the burden by ceasing to grow.  The body
thus responds by sparing those organs on which
continued existence depends.  When the crisis is
over, the bones proceed to grow again.  The marks
of this arrest in growth are visible in the X-ray
film as transverse lines.  The frequency of their
occurrence has become appreciated only since the
X ray has come into general use.  The processes
involved in the formation of the transverse lines
has been studied on the rat by Park and Richter
in order to  clarify the basic mechanism involved.
The results  are detailed following a description
of the cellular structure of bone with an explana-
tion of the  separate roles of the cartilage cells
and osteoblasts,  necessary for the understanding
of the formation of arrest strata.
  In the clinical observation of the 800 cases  of
children dying from all causes,  but excluding in
this series  cases of Pb poisoning and those in
which Bi or  elemental P had been given, arrest
lines were exceedingly frequent.  They varied in
number from 1 to several at single bone ends, and
as to the bone on which they occurred.   In no in-
stances were they seen at the slow growing bone
ends when they were not more numerous or better
developed or both  at the faster growing ones.
There are instances when the arrest strata may be
present but  indistinguishable in the X-ray film.
The reasons  for this and for other factors, in-
cluding conditions under which the strata may
fail to form or may form incompletely, are ex-
plained.  Growth-arrest strata may persist into
adult life,  although almost always they are re-
sorbed as a  result of remodelling before linear
growth ceases.  As advised by radiologists, trans-
verse lines  are only occasionally seen in the
bones of adults.
  I'he differences in the transverse lines as a
consequence of nutritional stress, those occur-
ring in certain diseases that grossly affect bone
formation (rickets), lines of rarefaction seen in
X-ray films, and those caused in poisoning by
heavy metals and P are detailed.  The lines
caused under the latter conditions are entirely
different from those caused by arrest of growth
(or, as they should be more accurately termed,
post-arrest lines, for they become evident be-
cause of the recovery following arrest).  The
lines caused by P and Pb poisoning are described
as thicket strata which may be mm (Pb) or cm (P)
thick, although they also may be line thin.  The
reason for this is that there is no interference
with the continuation of cartilage (linear) growth
and that the action is on all bone in process of
formation, and constitutes an interference with
the mechanism whereby normally surplus bone is
removed (bone resorption).  Pb is considered to
retard bone growth.  In chronic  (childhood) poi-
soning the ingestion of Pb is almost always sub-
ject to variations at different  times.  Corre-
spondingly in the films the bones register bands
and lines of different thicknesses and intensities
of radiopacity interspersed at irregular intervals.
A characteristic picture, particularly if evidence
in remodelling is also present,  is a band 2-3 mm
                 wide at the extreme ends of the fast growing bones
                 together with lines and bands interspersed farther
                 down the shaft.  (27 references)

                 Data are presented which show that Pb lines (me-
                 tallic transverse bands at the ends of growing
                 long bones) are absent in most cases of early Pb
                 poisoning and that heavy transverse bands may be
                 found in apparently normal children.
                   The policy followed in the authors' institution
                 is to hospitalize all children with pica and baso-
                 philic stippling, and subject them to the ver-
                 senate diagnostic test.  Excessive ingestion of Pb
                 is indicated by urinary Pb content of >500 yg/1
                 after administration of versenate.  Roentgenograms
                 of the long bones of 31 children (9 mo-4.5 yr
                 old) with Pb poisoning and 17 control children
                 (10 mo-5 yr) were read independently by 3 observ-
                 ers.  The Pb poisoning cases were divided into 2
                 groups on the basis of their pre-versenate urinary
                 Pb levels:  14 with levels of <35 ug/1 were in-
                 cluded in the early Pb poisoning group; 17 with
                 levels = 35 yg/1 or who had evidence of encepha-
                 lopathy were placed in the late group.  Only 17%
                 of the patients with early Pb poisoning had posi-
                 tive or borderline roentgenograms, compared with
                 45% of the late cases.  Four of 8 children with
                 Pb encephalopathy had normal bone roentgenograms.
                 Two of the 17 control roentgenograms were read as
                 borderline by 1 observer, and 1 as positive by 2
                 and normal by 1 observer.  This was a case of
                 poliomyelitis with a history of pica who subse-
                 quently showed laboratory findings consistent with
                 plumb ism.
                   The conclusion was drawn that X-ray findings
                 should be given secondary consideration when diag-
                 nosing Pb poisoning and that absence of Pb lines
                 in the long bones should not discourage further
                 search for chemical evidence of plumb ism.

                 The major complications of Pb ingestion are en-
                 cephalopathy and neuropathy.  In children, en-
                 cephalopathy is the most common consequence of Pb
                 intoxication, whereas neuropathy is rare, only 9
                 cases having been reported in detail in the En-
                 glish literature, and 31 other cases mentioned.
                   A case of peripheral neuropathy due to Pb poi-
                 soning in a 3.j-yr-old male  child is described.
                 The child had a 2-yr history of pica and had
                 chewed several holes in the  plaster of his apart-
                 ment.  After anemia and weakness of 2-mo duration,
                 he developed a sore throat with vomiting and com-
                 plaints of pain in the thighs and legs.  Neuro-
                 logic examination revealed profound symmetrical
                 distal weakness of all extremities and some proxi-
                 mal weakness so that the child could not support
                 his weight.  Laboratory tests showed rare baso-
                 philic stippling, increased  excretion of urinary

coproporphyrins;  ALA excretion was 192.5 nM/day,
compared with a normal value of 20 yM/day.  i'he
Pb concentration in whole blood was 5 yg/100 ml.
X rays revealed dense metaphyseal bands in the
long bones.  Urinary Pb was within the normal
range prior to administration of CaNa2EDTA, but
increased 1000-fold after treatment with EDTA (2
courses of 7 days each of 75 mg/kg/day, given iv
in divided doses).  The child recovered completely
within 6 mo.  A discussion of the findings in com-
parison with those reported earlier led to the
conclusion that the determining factors in Pb-
induced neuropathy or encephalopathy must remain
speculative.

        PEDIATRIC LEAD POISONING.  Archives of
        Environmental Health 8:256-61 (Feb.),
        1964.
A review of the manifestations of pediatric Pb
poisoning and its differences from the adult dis-
ease is presented.  Pb poisoning in children de-
velops gradually, requiring persistent ingestion
of Pb-containing substances over a period of at
least 3 mo.  During the hot summer months, acute
manifestations may develop, indicating involve-
ment of the central nervous, gastrointestinal or
hematologic systems.   For early recognition of
the disease, judicious use of 4 laboratory tests -
ulood examination for anemia and erythrocytic
stippling, X rays of the long bones for "Pb lines"
and of the abdomen for radiopaque flecks within
the intestines, and urinalysis for coproporphy-
rins - is essential.   If any 2 of these tests
yield positive evidence, a tentative diagnosis of
plumbism should be made, a precise analysis for
Pb in the blood should be obtained and the pos-
sibility of encephalopathy considered.  Pb poison-
ing is most common among children, aged 15-36 mo,
residing in older, impoverished areas where the
walls of the houses have been painted repeatedly
and are now in poor condition.  Patients once
treated must be watched for recurrences and their
siblings checked carefully for the disease.
Treatment does not prevent fatality in 25% of the
cases with encephalopathy nor a high incidence of
neurologic and behavioral sequelae.  Therapy in-
cludes termination of exposure to Pb, removal of
Pb from the body through the use of chelates such
as ethylenediaminetetraacetate and dimercaptopro-
panol,  symptomatic treatment for encephalopathy
and prevention of re-exposure to Pb.   (From au-
thor 'b summary)  (19 references)

        POISONING.   Public Health Reports 79:167-
        74 (Feb.),  1964.
A review of the nature, sources and extent of Pb
poisoning indicates that it is a cause for major
concern as a health hazard to children <5 yr of
age, both in urban and  rural areas.  As a result
of the recent  practice  of obtaining blood Pb lev-
els in children who exhibit pica but are asympto-
matic, the definition of Pb poisoning is appar-
ently changing.  Diagnosis is being made with in-
creasing frequency  on the basis of elevated lev-
els of Pb in the blood without any symptomatic
manifestations of poisoning.
  Reporting of Pb poisoning to the Philadelphia
Department of  Public Health has been mandatory
since 1950.  The results of systematic investiga-
tion of all reported cases by the Department over
a period of >7 yr showed that ^657, of the
cases could definitely be attributed to paint as
a source of Pb; a toy was determined as the
source in 1 case.  There are many other known and
suspected sources; an attempt to list these in
order of likelihood of  cause has been made by
this Department.  The program, as developed in
Philadelphia,  is described in detail.  This in-
cludes seeking the cooperation of landlords in
the voluntary  removal of Pb paint when it is
found to be the source, epidemiologic investiga-
tion, education of the  public, aside from the
necessary laboratory services, and medical atten-
tion,  i* major limitation of the program has been
the lack of legal powers to enforce removal of
environmental hazards when they are discovered.
  The number of cases reported, and deaths among
them, in recent years are summarized for Phila-
delphia, Chicago, Baltimore, St. Louis, New York
City, and Cincinnati.   On the basis of this ex-
perience the author recommends preventive mea-
sures that must include screening of subclinical
cases, early and rapid  diagnosis, routine report-
ing, epidemiologic investigation, environmental
appraisals, education and counseling, enforcement
of legal standards, and adequate laboratory and
social services.  Minimization of the disease and
its sequelae is as important as prevention.  re-
search is needed into overt and underlying causes;
social, economic and cultural factors; physical
and psychiatric aspects of the condition and its
causation, and measures to control environmental
hazards.  (23  references)

Five cases of chronic Pb poisoning in children
living on the same street, are reported.   The pa-
tients were 3-14 yr old.  Pb poisoning was diag-
nosed on the basis of clinical and laboratory
tests.  All showed stippled erythrocytes; the
hemoglobin content was 50-80%; the concentrations
of Pb in blood ranged from 79-100 pg/100 ml, and
in urine from 150-275 ug/1.

  Inquiry into the cause of poisoning in the first
case so diagnosed revealed that the family dealt
in scrap metal; in fact, there were several such
workshops in the dwelling units on the street.
As the families appeared to live as a clan, with
the units interconnected by doors, the children
played in the workshops.  Two of the children
were treated 1st with daily doses of 20 g Na ci-
trate;  all of them were given 3-4 g of CaNa2EDTA/
day.
  The results were disappointing, partly due to
social conditions which precluded adequate mea-
oures against continued exposure to Pb .  The au-
chor questions the value of treatment of chronic
Pb poisoning and stresses the need of prevention,

The finding by A.A. Moncrleff et al  (Abstract No.
3060) that the Pb levels in the blood of mentally
retarded children and those with behavior dis-
orders were frequently higher than in normal
children, prompted the authors to investigate some
20 such patients in their hospital (out of 100).
Among them were 5 with cerebral palsy, who had
never been able to put anything in their mouths,
and who showed an average concentration of Pb in
blood of 13 ug/100 ml.  Among 12 others showing
>40 pg were 3 children in whom Pb poisoning was
suspected as the primary cause of their mental
deficiency:  (1) A boy, now 18 yr old, who had
begun to show mental retardation from age of 18
mo, showed in 1964 a level of 68 yg Pb in 100 ml
blood, which dropped to 39 pg after  treatment with
penicillamine.  Scrapings of paint of the cot that
he had used as a child contained 6.76% Pb.  (2) A
girl, now 12 yr old, who had chewed objects as a
baby and still had severe epilepsy and abnormal
electroencephalogram, showed 60 yg Pb/100 ml blood,
and after 1 mo's treatment with penicillamine, 16
pg.  (3) A boy, now 9 yr old, had 1st exhibited
signs of mental deterioration at age of 2-1/2 yr.
His blood contained 137 pg Pb/100 ml, and 37 pg
after 1 mo's treatment with penicillamine.  His
pica was still uncontrollable as he was found to
be eating putty containing red Pb, which caused
his blood Pb to rise to 80 pg.
  The authors point out that these findings suggest
that the incidence of Pb poisoning as a cause of
mental deficiency is >1/1000 found by J.M. Berg et
al (Abstract :N'O. 3046), and that routine blood-Pb
determinations in any child who exhibits unex-
plained epilepsy, mental deterioration,  or psy-
chotic behavior (regardless of pica)  might reveal
further cases.

Appreciable amounts of toxic substances (TEL, ben-
zene, P, C disulfide, Hg and 1,2-dichloroethane)
are found in the structural materials of industrial
buildings such as lumber, brick, concrete and
plaster.  Substances like 1,2-dichloroethane usu-
ally reach maximum absorption values within 1.5 hr
of exposure, but TEL absorbs more slowly (=20 hr).
The time of average exposure, concentration, nature
of the materials and other factors affect the
amounts of absorbed material.  Oil-paints are very
susceptible to uptake of chlorinated solvents,
but that of C disulfide is sharply reduced.  Plas-
ter composition of 1 part lime (containing Si di-
oxide 53, ferrous oxide-ferric oxide 20-30, Mn ox-
ide 10-20%), and 2 parts of sand shows little or
no absorption of TEL.

those who clean the type 0.42 ng; of those with the
heating vessels 8.38 ing.  Exposure of monotypists
not in the immediate proximity of the melting  pots
was 0.06 mg, of tnose working without disturbing

layer 1.3 ing.  The amount was greatest among tue
recasters and the limits were widest.  \t tne en-
trance of the building the amount of I'b was only
0.04 ng/10 .11  of air,  at the mezzanine level where
the metal fragments discharge into tUe large vat,
0.55 mg;  if the contents are stirred and the scum

In electric arc welding, done either by hand or
machine, the metal to be welded is melted by the
electric arc and new metal is used with it.  Haz-
ards involved include electric shock or burns,
adverse effects from infrared radiation, visible
light of high intensity, ultraviolet radiation,
heat, and fumes from metals and fluxes.  Methods
of avoiding adverse effects from these are men-
tioned.  Ventilation must be adequate to remove
fumes given off during welding.  Fumes are a spe-
cial problem when welding is done in a small con-
fined space, and generally, mechanical ventila-
tion should be continued to allow a current of
fresh air to be drawn across from worker towards
the work.  In an unventilated enclosed space when
metals, electrodes, or fluxes containing Pb, or
other toxic metals are used, strict precautions
should be taken.  (From Bulletin of Hygiene 35:

        1950
As part of a. routine survey into health hazards
at a plant engaged in the manufacture of bath tubs
and sinks, Pb exposures were evaluated at enamel-
ing operations.  The enameling process is briefly
described.  It was found that air concentrations
of Pb ranged from 3.3-10.3 mg/10 m3 with the aver-
age worker exposure to Pb being of the order of
5 mg/10 m3.  Analysis of urine samples from 21
workers showed that 11 were excreting >0.30 mg of
Pb/1 of urine.  Only 4 showed <0.15 mg Pb/1.
Before control measures could be instituted, one
employee developed a mild case of Pb poisoning.

Environmental studies included analyses for Pb.
Only 3 samples for Pb were collected at one found-
ry, where patterns were made from white metal
which contained ^75% Pb.  Results of the analysis
showed 0.06 mg Pb/m  of air at melting and 0.007
mg at the finishing operation, which included
                grinding and routing.  Pb exposures in the ferrous
                foundries were intermittent and rarely encountered.
                It was concluded that Pb does not constitute a
                significant hazard in this industry group.

                Following a report received by the Louisville-
                Jefferson County Health Department that  2 workmen
                from  a Pb storage battery plant were hospitalized
                with  positive symptoms of Pb poisoning,  a survey
                of this plant was made by the Division.  As a
                part  of the survey, a detailed appraisal was made
                of the status of fume, dust, and vapor control.
                It was recommended that all operations evolving
                Pb fumes and dusts be hooded and mechanically ex-
                uausted.
                  The potential exposures in the pasting depart-
                ment  are sulfuric acid and Pb dust, and  Pb fumes
                in the group-burning department.  In the pasting
                department, the pasting machines and ovens are
                enclosed by hoods and the air exhausted.  In the
                group-burning department, slot hoods are located
                directly behind the operation.  Previous to the
                installation of these and other control measures
                in this plant, the concentration of Pb in the
                atmosphere exceeded  the MAC many times.  In sub-
                sequent determinations, the levels were within the
                acceptable limits.
                  Recommendations were also made that the plant
                initiate a clean-up and sanitation program.  Warn-
                ing posters provided by this Division informed
                the workmen of the hazard and nature of Pb poison-
                ing.  The utmost in  cooperation was obtained from
                the plant management.  The morale of workers in
                this  plant has increased, and several of them have
                expressed a pride in working for a company which

 Extensive recommendations to  improve the working
 environment in a Pb-Zn mine in Idaho were com-
 pletely carried out by management to assure the
 best health protection possible for miners, ac-
 cording to a report made by Idaho's industrial
 hygiene engineers.  During a  3-day survey of  the
 mine,  the 2 engineers  reported the need  for more
 ventilation, which was obtained in this  mine  by
 natural draft.   Extra  air doors were necessary
 to permit sufficient and proper circulation
 through the shafts and in the working levels.
   Excessive dust exposures of the underground
 workers were due not only to  inadequate  ventila-
 cion but also to such  practices as dry collaring
 of holes and to the use of insufficient  water
 spraying.
   This study was one of many  made in an  attempt
 to control conditions  that are crippling the
 lungs of miners.

 inadequacies in  procedures and ventilation  there
 had been no  lost  time cases of Pb poisoning in the
 2  yr of  operation,  the probable reasons being
 careful  observation  for  symptoms  and stippled
 cells  by both the  doctor and nurse; shifting of
 operators  if stippled cells appear; and the wear-
 ing of respirators at certain operations.

a  study  in a small pottery plant.  Each operation,
from the handling of raw material to firing the
figurines, was studied  for potential hazards to
the 26 workers employed at the plant.
   The highest Pb hazards were shown to be in the
following operations:  in the glaze laboratory
where the Pb content of the air was nearly 6 times
the MAC; spray staining which showed near MAC in
 the workers1 breathing zone and in glaze dipping
 where air samples showed 0.16 mg Pb/m  of air.
 The plant owner erected a new structure to house
 the hazardous operations.  Various control mea-
 sures were instituted.

 The  manufacture  of  electrical dry and wet storage
 batteries present certain specific hazards to the
 safety  and health of  production  workers and  have
 attracted the close attention of the  New  York
 State Department of Labor.  In 1950 the Division's
 pilot study  covered 17  battery manufacturers in
 New  York  State employing 1304 workers.  During  the
 last 6  mo of 1949 there were  27  lost  time acci-
 dents in  the industry.   In I  company  designated  Y,
 located on the west side of Manhattan,  which is  a
 medium  sized manufacturer of  automobile batteries
 employing ^17 workers,  the Pb poisoning hazard was
 greater than in  another company,  X (Brooklyn) 28
 workers,  since the  Y  company  casts its  own plates
 and  pastes them  in  addition to casting  connecting
 posts and terminals.  In the  interests  of produc-
 tion efficiency  and safety, the  plant has installed
 a  casting machine in  which the whole  operation  in-
 cluding pouring  of  the  molten Pb,  is  fully auto-
 matic and untouched by  workers'  hands.  These
 machines  have all their gears  and  moving  parts
 carefully guarded so  that fumes will  not  be  dan-
 gerous.   In  the  preliminary survey, the Labor De-
 partment  found that in  the last  6  mo  of 1949 one
 man  in  the mixing room  had contracted a slight case
 of Pb poisoning.  Further precautions were recom-
 mended.

The'activities of the International Labour Organi-
 zation  are reviewed.  The  following refers to
actions taken  in  regard  to Pb  poisoning:
  "A Recommendation was  adopted in 1919 whereby
women and young persons  should be  excluded from
various occupations involving  exposure  to Pb, and
 that where employment should be subject to cer-
 tain  conditions dealing,  inter alia, with  venti-
lation, cleanliness of workrooms, notification of
 cases of  poisoning, periodical medical  examina-
tion, washing  facilities and  special protective
clothing.
  The Convention on white Pb adopted by the Inter-
national Labour Conference in 1921 prohibited the
use of white Pb or sulphate of Pb in internal
painting,  making its use subject to- regulations.
The employment of women and young persons in any
painting work of an industrial character involving
the use of these pigments was prohibited.
  To facilitate the ratification of the Conven-
tion, the Office, in 1927, published a  comprehen-
sive account of the medical and technical aspects
of Pb poisoning and its prevention with gratifying
results as to ratification.  Twenty-seven coun-
tries have now ratified this Convention."

In a preliminary hygiene survey at the Baytown
Refinery in Texas, some hazardous exposures were
found.  The personnel were tested for signs of Pb
absorption and indications of poisoning.  The uri-
uary excretion of Pb was utilized as the chief
gauge; however, a few atmospheric tests were also
made.  Occupational histories were obtained to
determine the relationship of job classification
and exposure to Pb.  The results are discussed
from the aspects of the importance of the problem
and of the control measures needed, many of which
were put into practice.  They included:  (1) Use
of non-Pb paints for spraying when possible; (2)
use of extension pipe on spray-gun when possible;
(3) working up-wind and using fresh-air supplied
personal protective equipment when necessary; (4)
use of brushes where no other control method as-
sures safe exposure; (5) informing men of the dan-
ger involved; (6) insistence on sanitary rules;
(7) continuing work on various protecting devices;
and (8) continuing urinary Pb tests to watch for
exposure.  Since those measures were adopted there
have been no cases of Pb intoxication in the plant.

It was found that air containing <1 pg Pb/m  did
not cause Pb poisoning in the workers employed in

        TRATED BY A PLANT STUDY.   American Jour-

A philosophy of the place of the official health
agency in private industry is presented.  The bas-
ic principles to be observed by a governmental in-
dustrial hygiene agency, if its work is to be suc-
cessful, are as follows:  1.  It has primary re-
sponsibility to safeguard the health of workers.
2.  Its technical work and its policies must be
unbiased.  3.  It must be able to speak authori-
tatively regarding health hazards and the adequacy
                of measures for protecting the health of employees.
                4.  It must be able to interpret intelligently its
                program to labor and management and to the health
                professions.  5.  It should endeavor so to conduct
                studies that not only the plant's previous methods
                and programs but also its own are improved thereby.
                The opportunity to test these principles was a re-
                quest of the Bureau of Adult Health of California
                by the union of a large Pb smelter for medical
                advice on the Pb problem.  The findings of the
                study which resulted after the conferences with
                the union and company representatives, the policy
                in reporting, the follow-up and evaluation of re-
                sults are described.
                  The findings, as summarized, indicated inade-
                quately controlled, large-scale materials handling
                and processing operations; secondary sources of
                settled dust contributed to a general plant con-
                tamination near 0.15 mg Pb/m^ air (MAC), and in
                weighted employee exposures exceeding this figure
                at all operations studied.  These resulted in part
                from inadequate maintenance of control equipment.
                In 20% of employees examined  (108 from 542), 82%
                showed either excessive Pb excretion or more posi-
                tive findings which were relatively mild.  A di-
                rect correlation between increased Pb exposure and
                frequency of clinical findings was established.
                Recommendations included establishment of a con-
                tinuously operating local engineering control pro-
                gram, and participation of employees in measures
                for their health protection, by the establishment
                of an employee-management health committee.

                        INSTALL VENTILATION TO PROTECT WORKERS
                        FROM LEAD.  Occupational Health 12:44
                        (March), 1952.
                Approximately 50 paint plants were visited by the
                Cleveland Bureau of Industrial Hygiene to deter-
                mine the amount of Pb exposure.  About 28 were
                found to mix Pb paints routinely during the sea-
                son, and a few others made several batches/mo.
                One plant used 1600 Ib of Pb-Zn in a batch of
                paint several times/wk.  Air samples taken in the
                breathing zone of the workman emptying 50-lb bags
                of Pb-Zn through an opening in the floor into a
                mixer showed >8 mg Pb/m  .  Samples taken a few
                minutes after this operation showed 0.56 mg.  The
                workman was wearing a respirator which he said
                was more comfortable and easier to breathe through
                than some.  nis attention was called to the fact
                that it was worn upside down and had spaces
                alongside of his nose large enough to insert 2
                fingers so that it was entirely ineffective and
                naturally would cause no resistance.  The expo-
                sure of this workman would be hard to estimate
                because the bag-emptying operation lasted only a
                few minutes and the dust was heavy enough to set-
                tle rapidly so that general air dilution reduced
                his exposure considerably between mixing.  Mixing
                generally occurs several times daily during the
                rush season, and there may be 6 mo or more when
                no Pb paints are mixed.  Only 1 reported case of
                Pb poisoning due to paint mixing occurred and
                that resulted in the death of the workman.  There
                undoubtedly have been many cases which have never
                been reported; but, on the other hand, many of
                the workmen in paint plants are well along in
                years and apparently do not complain of poor

 health.
   After  this  plant  installed  local  exhaust  ven-
 tilation,  air samples  taken while emptying  about
 the same quantity of Pb-Zn showed 0.16  mg Pb/m3
 in the breathing zone  of  the  workmen.   The  resid-
 ual concentration found a few minutes later was
 0.u7 mg.   The reduction from  8-0.16 mg  was  a
 decided  improvement.   In  some other plants, the
 exposure had  been much greater  and  when ventila-
 tion was installed  the reduction was even more
 dramatic.

 3092     Anonymous:  ENGINEERING AND MEDICAL SUR-
         VEY OF TILE PLANT INDICATES LEAD EXPOSURE.
         Occupational Health 12:54 (Apr.), 1952.
 At  the request of the  California State  Division
 of  Industrial  Safety and  with the cooperation of
 management and labor,  a tile  plant  employing ^275
 men and  women was surveyed for  a possible Pb or
 silica hazard  by the Industrial Hygiene  Division
 of  the Los Angeles  County Health Department.  The
 plant medical  department  consisted  of a  full-time
 industrial nurse and an on-call physician.  There
 was no plant  safety engineer.
   In the engineering survey,  only 2 of  the  18 air
 samples  were  within permissible limits.  The
 highest  levels were found at  the mixer  loading
 operation; the frit furnace area was 2nd, and the
 spray rig  area, 3rd.   Medical examination showed
 that 6 out of  41 blood specimens drawn  from em-
 ployees  working with Pb materials contained 0.09
 or  more  mg Pb/100 g of whole  blood.  Two of them
 were glaze preparers,  and 4 worked  on the spray
 rig operation.  Repeat blood  tests  were  done at
 about monthly  intervals on these individuals.
 Preventive and protective measures  were  discussed
 with the employees, and management  offered  some
 of  them  the option  of  working on non-Pb  jobs tem-
 porarily.  In  ^4 mo, analyses revealed  the  amount
 of  Pb in blood within  normal  limits.  Three of
 those whose blood showed  Pb above normal limits
 had no signs or symptoms  of Pb  intoxication as
 manifested by  the basic medical survey.   Many of
 those within normal blood Pb  limits related sub-
 jective  symptoms which one might have expected in
 those whose blood Pb exceeded normal limits.

 Sulfo-white Pb is  superior to the carbonate for
use  as a paint pigment, and the health hazards in
 its  manufacture are far less extensive.   Also, no
difficulty has been encountered with neighborhood
 contamination.  This is in spite of the fact that
sulfo-white Pb has   the same toxiclty as  the basic
Pb carbonate.    (From Zentralblatt ftlr Arbeitsmedi-

        WORKERS.)   Deut.  Gesundheitswesen 7:953-
        3 (July 24), 1952.
The author  describes the measures of medical su-
pervision exercised over 95  Pb mixers  and solder-
ers, exposed to both dust and fume.
  In addition to adequate ventilation, insistence
on personal cleanliness, with the provision of
changes of clothing, baths and mouth washes, and
the wearing of masks and respirators, special
medical supervision includes:
  1.  Systematic inspection of workrooms by the
works doctor, chiefly as a control of the effi-
cacy of ventilation.  2.  Periodic estimation of
the atmospheric concentration of Pb; this was
consistently found to be <1.5 mg/100 m3 air.
3.  Medical examination of all workers every 6
mo.  This included inspection of the mouth for
"olue line"; blood examinations, especially for
punctate basophilia; urine examination; blood
pressure readings; weight measurements and chest
examination.  Since 1950 yearly estimations of Pb
in blood and urine have also been made.  Inspec-
tion of the mouth showed no "blue line"; there
was a high incidence of loss of teeth but this
could not be specifically ascribed to Pb poison-
ing since 82% of these workers were in the higher
age-^roup and had suffered from nutritional in-
adequacy during the war years.  Punctate baso-
philia is regarded as the most important aspect
of blood examinations.  The average level found in
79.5% of all cases was 500/million erythrocytes;
the highest ranged from 4800-13,200.   None of
these subjects showed any symptoms of ill health
but there was some correlation between high lev-
els and careless habits leading to intake of Pb.
The average level of Hb was 92% and of erythro-
cytes 4,988,000/mm3.  The author does not consider
estimation of porphyrinuria a necessary factor of
medical supervision, punctate basophilia being the
simplest and most reliable criterion.  Estimation
of Pb in blood and urine was done only for differ-
ential diagnosis.  The average amount of Pb in
blood was 0.063 mg/100 ml,  and in urine 0.114
mg/24-hr specimen, compared with the recognized
"critical levels" of 0.06 mg for blood and 0.1
mg for urine.  Blood pressure estimations gave no
indication of a raised level in these workers,
rather there was a tendency to hypotonia, which
the author is inclined to associate with a low
protein wartime diet.  4.  Periodical short medi-
cal report on general health risks and protective
measures.  The author concludes that the simplest
and most reliable measures of medical supervision
is the estimation of punctate basophilia, Hb lev-
el and total number of erythrocytes.  (From Bul-

Pb and Fe were found to produce explosive sub-
stances from trinitrotoluene in the presence of
HN03 which can be ignited by heat, shock, fric-
tion, or contact with concentrated nitric and
sulfuric acids.   Since Al forms much less sensi-
tive compounds its use is recommended.  Metallic
salts of Pb and Fe were found at the scene of
explosions, lending support to the theory.  (From

3097     Park, W.E.  (Minnesota Dept. Health, Min-
        neapolis) :   RIVETERS  ON RAILROAD BRIDGE
        EXPOSED TO LEAD FUMES.  Occupational
        Health 12:66, 78-9 (May), 1952.
A report of Pb poisoning early in 1950 focused at-
tention on a hot-riveting operation on a railroad
bridge.  The report arrived after the work was
completed, so  that  no study could be made.  When
a similar operation was being performed late in
1951  in Minneapolis, a study of atmospheric Pb
concentrations was  made.
  In  order to  permit movement of railroad traffic,
solid steel plates were placed over the beams, and
tracks were laid before the beams and cross
braces were riveted.  This meant that hot  rivet-
ing had to be  done in confined spaces ^3 x 6 x 3
ft, which were open only at the bottom.  The
steel was covered by an orange-colored Pb-contain-
ing paint.  The paint burned off for ^1 in around
each  rivet, producing a smoke which was very ir-
ritating to the eyes and upper respiratory pas-
sages of the workmen.  The men were exposed
throughout an  8-hr day over a period of ^2 mo.
Because of the intense cold,  the workmen could
wear  respirators only for a short time, until they
became frosted.  On a very cold and somewhat windy
day in December 1950, the engineers of the Divi-
sion  took several samples of air at the breathing
level of the workmen.  The average of 3 samples
taken during the time the workmen were driving
rivets was 6.4 mg Pb/m-5 of air.  The average of  3
samples taken  while the men were bucking rivets
was 8.2 mg/m  .  Clinical studies of the workers
were  not made.
  This study demonstrated that a Pb exposure is
possible during outdoor work when the worker's
head  and shoulders are confined in a small space
as they were  in the riveting job on the railroad
bridge.  To control the irritating smoke and Pb
hazard, portable blowers supplying heated  air were
recommended.

        GASOLINE USED IN CARBON BLASTING POISONS
        MECHANIC.  Occupational Health 12:160-1
         (Oct.) , 1952.
It has been assumed that Pb gasoline when  it  is
burned in a high compression engine has then ex-
                Bended itself.  Such is not the case.  It sti1!
                has the power to cause Pb poisoning.
                  In looking for the cause of Pb poisoning in a
                garage mechanic in Minneapolis, the  trail led to
                a comparatively new process known as carbon blast-
                ing.
                  A study of several machines was conducted at
                Minneapolis jointly by the Minneapolis Health De-
                partment and the Minnesota Department of Health,
                Division of Industrial Health.  C powder, which
                was caught in the filter, was found  to contain
                ^55% Pb by weight, believed to be derived from
                the TEL in the gasoline consumed.
                  Exposure under the open hood of the car was
                particularly high, so that the operator bending
                over the engine could have considerable quantities
                of the C-Pb powder blown up in his face.  Another
                operation which provided a heavy exposure was
                cleaning of the filter.  The atmospheric Pb lev-
                els during C blasting at breathing level of the
                operator averaged from 1.0-10.2 mg/m of air, the
                general atmosphere 2-5 ft from the car averaged
                from 0.06-0.35 mg/m-5, and at breathing level of
                operator while cleaning filter ranged from 1.9-
                41.0.  In some instances, workmen became further
                exposed to the C-Pb dust by eating and smoking
                without washing.  Usually the operators' hands
                were heavily coated by the black powder.
                  In the 1 case of Pb poisoning attributed to this
                type of exposure, the employee worked at C blast-
                ing continuously for 3 wk, cleaning  the engines of
                ^3 cars/day or an average of 15 cars/wk.  When he
                was seen by his personal physician,  he exhibited
                the usual symptoms of acute Pb poisoning and his
                urinary Pb concentration was found to be 0.39 mg/1
                of urine.  Changes in the design have been sug-
                gested which should make the machine reasonably
                safe under ordinary operating conditions.
                  Garages are being advised to require their oper-
                ators to wear respirators approved for protection
                against Pb dusts so long as they are using the
                present C blasting machines.  They are also urged
                to discontinue use of the present machine as soon
                as a machine is available which eliminates the
                hazard of Pb poisoning.  Operators are warned to
                wash well before eating or smoking.  Further
                studies are being conducted to evaluate the Pb
                hazard associated with other methods currently
                being used for removing C from automotive and air-
                craft engines.

the breathing level of the worker was aspirated
through 6N nitric acid and analyzed for Pb.  Eight-
hour urine samples were collected from various
workers at a remote point outside the factory to
prevent the samples from becoming contaminated with
Pb dust.  Blood examinations of the workers could
not be performed for various reasons.
  The Pb concentration per 10 m  of air was found
to vary from 116 mg/10 m-^ at the lowest to a maxi-
mum of 3707 mg/10 m3.  The Pb content in the urine
of all the workers examined ranged from 0.20-13.04
mg/1 urine.  These values were consistently above
the level generally accepted for normal individuals
not exposed to Pb.  However, these high values were
not considered necessarily to warrant a presumption
of Pb poisoning since the exact figure at which the
rise in urinary Pb excretion indicates intoxication
has not yet been definitely established.  None of
the workers studied during the 3-wk clinical ex-
amination showed any signs or symptoms of Pb poison-
ing.  Turnover among the employees was high, few
continuing at their jobs for >6 mo, and even these
short periods were interrupted by much absenteeism
which may explain the fact that serious cases of
Pb intoxication had not occurred during the short
span of employment.  Later occurrence of any ill-
ness would not be likely to be associated with Pb
exposure by the uninformed workers nor would any
steps be taken to apply for compensation.
  Thus, without a carefully planned social follow-
up, the damage done to the health of the workers by
their 6-12 mo period of employment was difficult to
assess.  Urine excretion was strikingly lower in
winter than in summer in these workers during 8-hr
collection periods  (6 AM-2 PM) in the winter of
1950-51.  The commonest complaints of the workers,
new or old, were loss of appetite, constipation,
occasional headaches and bad taste in the mouth.
Those working for longer periods also mentioned
severe stomach pain and gradually increasing weak-
ness.  Some of them complained of pain in joints
and muscles, a characteristic of Pb arthralgia.

        AUTO ENGINES EXPOSED TO LEAD DUST.  Occu-
        pational Health 12:200 (Dec.), 1952.
An Indianapolis physician thought that 1 of his
patients developed Pb poisoning while cleaning
automobile engines with a C-blasting machine.
This machine used ground walnut shells as the
abrasive, feeding the shells into the motor by a
blast of air at 40-60 Ib/in  pressure.  It had
been shown that the C deposits in the motor be-
come contaminated with Pb when Pb-jasollne is used.
Dust collected by the physician contained 45% Pb.
Urinary Pb determined 5 wk after the exposure,
showed 0.262 mg of Pb/1.   Jith this clinical back-
ground, the Division of Industrial Hygiene under-
took some atmospheric Pb  studies in the garage
where the patient worked.  The manufacturer of the
blasting machine, who was present during the study,
stated that similar studies had been done by the
Division of Industrial Hygiene,  Minnesota Depart-
ment  of Health,  on June 4.   Studies  by the author'^
Division on Sept  3,  1952, substantiated the Minne-
sota findings.   Following the latter,  the manufac-
turer redesigned  the machine by  adding a screw
type nozzle to the cylinder head and installing an
additional bag collector in the machine.  The old
machines used a rubber stopper on the cylinder
head.  The results of the author's atmospheric
studies were as follows:
  1. New machine, nozzle plug screwed into cylinder
head, 2 filter bags and operated at 45 Ib/in  in
rag/m^:  breathing zone of operator under hood
0.136; under unit at air exhaust 0.820; general at-
mosphere near unit 0.175.  2.  Old machine (where
patient worked): breathing zone of operator under
hood 2.39; under unit at air exhaust  7.55; general
atmosphere near unit 0.121.  3. Same as test 2
except deflector ring was in machine:  breathing
zone of operator under hood 0.252; under unit at
air exhaust 3.140; general atmosphere near lid of
unit I.o78.  4. Another old machine but a little
later model:  breathing zone of operator under
hood 1.57; under unit at air exhaust 1.44; general
atmosphere near unit 0.174.
  until these machines are so designed as to elim-
inate the Pb hazard, all routine personal pro-
tective measures must be used.  Every garage in
Indiana was informed of the Pb hazard present and
what controls are necessary.

Pine lumber treated with TEL was not decontaminat-
ed by 8 surface applications of chlorinated lime
during 60 hr.   Dichloramine-T was effective to the
depth of 0.5 cm with TEL concentrations up to 0.05
g/cm^ of the lumber surface; usually a 4-hr treat-
ment with 10% solution was satisfactory, followed
by 2-6 further washings.  Deeper penetration and
heavier contamination could be removed even in 13
hr.  S02C12 (15% solution in C1CH2CH2C1) was rap-
idly active for mild contaminations and effective
even for deep contaminations after 60-hr exposure,
but the wood lost its mechanical strength after
such treatment.  A 5% solution of C12 in C1CH2CH2-
Cl gave rather good results in 2-6-hr treatment,
but the results were not appreciably better than
those of other methods.  Wood contaminated to a
depth of 0.6-3.0 cm could be satisfactorily decon-
taminated.

This is a detailed account of the industrial
health aspects of this industry which in Italy has
not been mechanized or organized on mass produc-
tion lines.  There are 30 factories, mostly in the
North.  A minority employ >100 men, the labor
strength of most of the others varying between 50
and 100.  A few small tradesmen still manufacture
batteries with the help of only 5 or 6 employees.
"Hand" methods of manufacture seem to be more
suitable to the local market, which demands a
wide range of models to suit a variety of pur-
poses; the hand-made article is said to last
twice as long as the mass-produced equivalent.

The author has surveyed 15 representative facto-
ries employing from 5-400 men.
  Troisi points out that Pb may be absorbed by the
respiratory, the digestive or the cutaneous route;
he thinks the first to be the most important.   He
lists the various jobs and processes which are
entailed in this manufacture and points out the
health hazard presented at each stage.  He dis-
cusses appropriate preventive measures including
personal hygiene, regular washing down of benches,
floors, etc, and exhaust ventilation at the point
where fumes, vapors or dusts are produced.  He
stresses that exhaust arrangements should be by
downward draught, and that fumes, etc, should be
prevented as far as possible from reaching the
level of the atmosphere which is in the vicinity
of the operator's mouth and nostrils.  He dis-
cusses medical examination on admission, the con-
ditions for which employment for this occupation
should be advised against, and periodical medical
examination of those at work.  The treatment of
those who show evidence of absorption and the use
of milk and of Ca are discussed.  (32 references)

        AND POURING OPERATIONS.  American Foundry-
        man 21:125-31 (Apr.), 1952.
Some reasons why ventilation of furnace and pour-
ing operations is essential are presented.  These
are based on experiences with litigation cases,
with occupational disease such as Pb poisoning, and
with labor relations.  A typical case is presented
of a man who died of uremic poisoning, diagnosed by
the family physician as Pb poisoning because the
man worked in a brass foundry.  The company lost
this case and had to pay compensation.  The inci-
dence of Pb poisoning as found in a 5-yr study
depended on chemical composition and particle size
in melting and pouring operations.  For instance,
in the machine shop where Pb dust amounted to 4.9
mg/10 m3, 2.8% of the men suffered attacks of Pb
poisoning; however, in the furnace bay, exposure
to 4.95 mg caused 57% to be so affected.  Costs,
practical applications, and deficiencies of typi-
cal exhaust ventilation from melting and pouring
operations are described and illustrated by photo-
graphs of equipment.  The results obtained so far
indicate that a favorable solution of the problem
has been found.  The examples given of methods of
exhausting typical nonferrous pouring and melting
operations have been found effective and practical.
They are relatively cheap measured in terms of the
factors pointed out previously in this paper.

                 In  a  plant  producing calendered  and  extended  poly-
                 vinyl chloride film,  effective control  of the Pb
                 dust  hazard was  accomplished with  the  use of  a
                 minimum of  exhaust ventilation.   The manufacturing
                 operations  differ in this  plant  from those  common
                 in  the  industry  in that  Pb compounds as well  as
                 other powdered stabilizers,  colors  or  pigments  are
                 (1) transferred  from their original  containers  in
                 an  exhausted enclosure and (2) either  processed
                 into  non-dusty forms  or  (3)  weighed  into plastic
                 bags  and sealed  before entering  the  factory proper.
                 The new method for this  and  other  manufacturing
                 operations  as  well as the  common practice of  the
                 manufacturing  process are  described  and illustrated
                 by  photographs.   The common  method in which the at-
                 mospheric concentration  of Pb  exceeded  the  MAC
                 value of 0.15  mg/m^  of air necessitated the con-
                 tinuous wearing  of an approved dust  respirator.
                 At  the  plant using the new method,  the  worker wore
                 an  air-supplied  helmet during  the  transfer  of the
                 Pb  stabilizer  to the  blender for a total work peri-
                 od  of only  20-30 min/day,  and  on only  1 of  the  3
                 shifts.   Inhalation  values of  Pb in  the plant were
                 below the MAC  value.  The  atmospheric  concentra-
                 tions were  also  below the  MAC  value  except  for  the
                 actual  weighing  of the Pb  stabilizer, but this  op-
                 eration is  controlled by the use of  an  air-supplied
                 helmet  for  maximum protection  of the worker.  Uri-
                 nary  Pb concentrations  (method of  analysis  based
                 on  the  work of Reed  et al, 1942),  varying from
                 0.02-0.10 mg/1 of urine, were  well within the
                 limits  set  for workers exposed to  Pb and within
                 or  near the range for non-exposed  persons.

                 A request had  been made  for  an environmental
                 health  survey  at all United  States mints.  Pre-
                 liminary surveys and studies were conducted during
                 the period  1947-50 and a number  of recommendations
                 were  made to control potentially hazardous  expo-
                 sures.   The major potential  health hazards  were
                 found to be Pb and Zn fume;  acid mists  and/or
                 gases;  smoke and gases  from  furnaces;  dusts con-
                 taining a variety of metals.  An environmental
                 resurvey was  conducted  in  1951 in all  4 mints.
                 Most  of the previous  recommendations for the  con-
                 trol  of atmospheric  contaminants,  improved  light-
                 ing,  and sanitary facilities had been  complied
                 with.  A number  of air samples were  collected at
                 the site of each type of operation and  of the
                 general room air. Analyses  of these samples
                 showed that, in  most cases,  exposure of workers to
                 fumes of Pb, Zn, Se,  Te, acid  mists  and/or gases,
                 and dust was well below  the  threshold  limit values
                 adopted by  the American  Conference of  Governmental
                 Industrial  Hygienists in 1951.

 A survey of  electrical welding operations was made
 as  a  result  of  complaints  from workers of irrita-
 tion  of  upper respiratory  passages, nausea, head-
 aches from the  first hours of work, even in new
 men.   .Analysis  of fumes showed the presence of
 600 ug Pb/m  .   I'he  authors state that they present
 no  clinical  results, nor will they be prescribed
 in  the future because efficient exhaust systems
 were  installed  immediately, and further air analy-
 sis showed no Pb in the ambient atmosphere.

        32:205-12 (Mar.), 1953.
The working of mineral mines in  Morocco is com-
paratively new and the minerals  have so far been
found far from inhabited areas away  in the des-
erts, where water is scarce and  the  heat great.
At present little or nothing has been done to
study the conditions of work in  the  mines or the
diseases which are almost certainly  occurring.
Reliance must be placed upon research carried out
in other civilized countries.  This  article gath-
ers such information and points  out  how it should
be advantageously used in Morocco.  Fears are ex-
pressed about Pb poisoning in mines  where Pb ores
are obtained; but as the Pb occurs as galena, the
insoluble Pb sulfide, the risk must  be small.
(Such ore usually occurs associated  with a quartz
matrix with a risk of silicosis.) Other hazards
are discussed among which Mn seems to be the most
important.  The need for sanitation, preemployment
medical examinations and periodic examinations
during employment are also covered.   (From Bulle-

nation from the exhaust from the process of C
blasting and eliminate as much as possible Pb poi-

filter is used in connection with a  secondary fil-
ter the exhaust stream content of Pb is reduced to
a point considerably below the MAC of 0.15 mg/m .

The Pb content of the air in a storage battery fac-
tory was  estimated by the polarographic method with
the following results:  (1) Pb content of the air
in a welding room showed a marked increase by the
use of a larger welding flame; (2) a simple mask
devised to prevent the exposure to Pb fumes and
dusts reduced the Pb content of the air inside
the mask by 1/2 of that outside the mask.

The 3 ir,ain tests used to detect excessive Pb ab-
sorption at the author's plant, are counting of
stippled cells (SC), measuring Pb in air, and
estimating Pb in urine.  The upper limit for the
mean SC count is 1500/million red cells.  It is
generally agreed that an upper limit of 1.5 mg Pb/
10 m  of air is the MAC.  Spot samples of urine are
collected from each worker once or twice a year
and analyzed by a dithizone colorimetric method.
Anything over ^200 mg/1 (sic, should be ug)  is re-
garded as excessive.  Where any dust is formed
during the process,  adequate local air extraction
should be available, preferably as part of a
plenum system.  All workshops must be clean and
tidy.  Where the process permits, the floors and
benches are constantly washed down and kept wet.
Elsewhere, wet sawdust is used for sweeping or, in
certain cases, a special type of vacuum cleaner is
used, which will prevent the escape of Pb dust
through the bag into the atmosphere.  Where any of
the tests show that excessive amounts of Pb are
being absorbed, the job method may be changed, or
ventilation improved.  Protective clothing,  proper
washing facilities,  and adequate washing time are
all essential safeguards to the workers' health,
and the regulations specify minimum standards.  No
smoking or eating is allowed in the workshops,
under the regulations, in order to prevent the
swallowing of Pb.

A plant was suddenly confronted with 3 cases of Pb
poisoning among the workers because Pb was handled
and used without regard to its toxicity.  In the
initial atmospheric  survey, Pb contents in air
ranged up to 5.3 mg/1; coproporphyrin (CP) in
workers up to 1.65 mg/1, and stippled cells up to
O.y%.  By the installation of an adequate venti-
 lating  system, rotation  of workers with  high uri-
 aary Pb and  CP values, institution of  good house-
 keeping program, and scrupulous  follow-up of the
 other workers by medical screening tests, the
 situation was checked and progressively  improved.
 The study again reveals  the  importance of urinary
 CP tests as  an aid  in the early  diagnosis and pre-
 vention of Pb intoxication.

        (Aug.), 1954.
 The results  of laboratory tests  are reported which
 show the effects on Pb concentration in  the work-
 er's breathing zone of long  (60  in) vs short (18
 in) cutting  torches, removal of  paint by flame
 cleaning before cutting  and width of precleaned
 strip,  cutting was done horizontally on flat
 plates, 7-12 in long and 7/16-7/8 in thick,
 painted with an average  concentration of 1 g/in
 of surface using a  51.2% Pb paint.  The  cutting
 was done in  a 3-sided alcove vented to a court-
 yard.  Exposures ranged  from 2.8-84.2 mg/m-' as Pb.
 Results showed that breathing zone concentrations
 were higher  for flame cleaning with the  long probe
 than with the short probe (owing to necessity for
 cutter to stand almost directly  over work when
 using the awkward long probe).   The exposure to Pb
 fume in cutting painted  steel was appreciably but
 still not sufficiently reduced by removing a strip
 of paint along the line  of the cut prior to cut-
 ting or by cutting with  a long-Handled torch.  A
 2-in width flame-cleaned strip produced  the lowest
concentrations for subsequent flame cutting.  The
aggregate Pb-fume exposure from  flame cleaning
 followed by  flame cutting of the flame-cleaned
 strip was as great or greater than that  from flame
 cutting of the painted surface without prior paint
 removal.  All results showed concentrations >MAC.
 The approved Pb fume-type respirator did not fur-
nish complete protection against organic vapors
 released from the burning of the paint.  Respira-
 tory protection should be either an air-]ine or
 combination  Pb-fume and  organic vapor respirator.

Pb bronze contains 70-77% of Cu  and 20-25% of Pb,
and when heated at the necessary high temperature
emits Pb fumes from ovens, crucibles and furnaces.
 In spite of  technically  adequate exhaust ventila-
tion in a foundry,  sporadic cases of Pb poisoning
occurred,  and estimation of the Pb content of the
air in the foundry showed alarmingly high levels.
This was found to be due  to the fact that the hot
gases were condensed in  the metal chimney and
blown back by the wind through open windows.  Pre-
vention was achieved by  the use of Polak's appara-
tus consisting of a short cooling tube fixed diag-
onally into the exhaust pipe, its lower end pro-
jecting ^40 cm beyond it, and opening in the
shade,  the upper end above the roof in the sun-

light.  The hot gases passing upwards through the
cooling tube are condensed by the cold outer air
and the solid constituents are deposited on its
wall.  The deposit of Pb falling as fine dust into
a metal vessel at the lower end of the exhaust
tube must be removed every 4-6 wk on non-working
days.  It is claimed that this is a simple, cheap
and effective method of preventing accumulation of
Pb dust in the air of the foundry.

parts were first covered with paint to protect
against rust, the paint containing large amounts
of minium or red Pb which is oxide or binoxide
of Pb.  Rivets (heated to 1000°C) were placed in
holes and pressure applied by pneumatic hammers
or hydraulically (rivets being ^800°C at this
time).  When the pressure was applied the Pb paint
gave off clouds of fumes containing oxides of Pb
which contaminated the air of the workplace, es-
pecially the area breathed by the riveters.  Air
in the large halls where the work was done con-
tained 0.086 mg Pb/m-^; that at the level of the
nose and mouth of the riveters, 4.8 mg/m^ (in ex-
cess of the permissible limit).  None of the cases
of poisoning was severe, severity varying directly
with the length of exposure to the fumes.  Other
contamination, ie, handling of wet paint, eating
with unwashed hands, not using respirators fur-
aished, may also have been significant.  Although
improvement was obtained by better ventilation,
the suggestion of using paint without Pb did not
meet approval.  All cases occurred within 2-3 mo,
during which time the process was in action more
continuously than usual.  The men complained of
fatigue, lumbar pains, gastric neuralgia and ab-
dominal colic; they showed blue lines on their
gums, basophilic red cells and, in those most se-
verely exposed, reduction in red cell count which
disappeared on cessation of work.  One man had
some polyneuritis and one some nephritis.  The
author expresses astonishment that the risk had
not come under observation sooner.  (From Bulletin

                Since oxides of Pb are the form in which Pb is rec-
                ognized to be especially toxic, industries in Japan
                were selected in which such oxides are manipulated,
                such as storage battery plants, Pb refineries, Pb
                welding plants and Pb casting factories.  In places
                selected, air samples were analyzed to determine Pb
                concentration in air.  (Concentrations of 0.49-
                1.189 mg/m^ were found.)  Male employees 20-50 yr
                of age were selected who had been at work for at
                least 1 yr.  Reaction to Pb was soon found to be
                most pronounced during early weeks and months of em-
                ployment, but became fairly steady after 1 yr.
                These men were most  carefully examined clinically,
                physically and by analyses of blood and excreta.
                (Examination  included stippled cell counts, urine
                coproporphyrin, Pb in blood and urine, frequency of
                usual signs and symptoms.)  Statistical study was
                then made to  establish a correlation between concen-
                trations of Pb found in air and clinical and labora-
                tory results.  The statistical method  employed is
                explained and graphs are drawn showing results.
                Findings indicated that when Pb concentration in air
                is <0.05 mg/m^, work can be carried on for a long
                time with practically no injurious effect.  As was
                expected, a definite relationship was  found between
                Pb concentration in  air and clinical  symptoms.  How-
                ever, at 0.5  mg/m3,  which has been the legal allow-
                able limit in Japan, disabling Pb poisoning has
                been seen.  After carefully weighing  all available
                evidence as well as  results of this study, a maxi-
                mum allowable concentration of Pb in  industrial air
                was placed at 0.05 mg/m^.

                with Pb the dusts arising from various Pb-contain-

workers.  The Pb content of sweepings was also
determined.  Since clinical examination had led
the authors to the conclusion that risks of ab-
sorption of Pb vary with the nature of the alloy,
they chose 4 formulas for study: (1) Cu-Pb alloy
with 25% Pb; (2) complex alloy with 15% Pb; (3)
Cu-Sn-Sb-Pb alloy with 75% Pb; (4) soldering al-
loy with 75% Pb.  It was found that the actual
risks depend principally upon solubility of the
Pb compounds handled, particle size, as well as
the precautions taken.  This is illustrated by 2
cases: in one, the worker's blood Pb levels
amounted to 1400 yg/1 and he exhibited high stip-
ple cell counts, although no evident signs of poi-
soning developed.  He was in the habit of smoking
and eating at the work site without washing
hands, disregarding regulations.  The wash water
at the end of the day contained 57 mg Pb.  The
determination of Pb retained on the hands of
workers was made by treating the wash water (dou-
oly distilled) with acetic acid for the recovery
of Pb, followed by the molybdate method of analy-

MAC's for a number of metal fumes in processing
Be-Cu castings are discussed.  The heats contain
^O.iO% Pb.  The fumes from melted Pb are in the
form of the oxide.  Based on experience with
thousands of air, blood and urine samples the
present MAC of 0.15 mg/m^ is believed safe even
for susceptible persons.   Pb poisoning was not
found with continued exposures to concentrations
of 0.3 mg/m , but cases were experienced after a
5-yr exposure to concentrations of 0.5 mg/m3.

The highest admissible concentration of 0.05 yg
Pb/1 is consistently exceeded at all permanent
workplaces where Pb is worked up.  Up to a con-
centration of 1 yg/1, no signs of Pb poisoning
were found.  In the development of poisoning, ab-
sorption by respiration as well as by way of the
alimentary tract play a part.  Most occupational
diseases occur in dusty workplaces.  In evaluating
the workplace, it is necessary to take into con-
sideration not only the degree of contamination,
but also the type of substance being handled, to-
gether with its chemical composition and the size
of the aerosols.  For a rapid orientation as to
the amount of Pb actually inhaled in workplaces
where a respirator is used, simultaneously col-
lected samples of unfiltered air and of air
passed through the filter used by the workers,
can be used.  The observance of hygiene and pro-
duction regulations, the use of a cotton-wool
respirator and possibly the' suitable transfer of
persons working with high concentrations makes
it, in most cases, possible to avoid the develop-
ment of Pb poisoning.  A draft scheme for the
evaluation of individual workplaces with Pb is
elaborated together with proposals essential for
the protection of workers.   (From Excerpta Medica,

It is a fact that serious Pb intoxication in in-
dustry is rare;  but it is a fallacy to believe
that the incidence that does occur has no signifi-
cance.  Several instances are given in which large
companies refused to consider the evidence of Pb
poisoning in their plants and thereby sustained
large losses in compensation awards.   On the other
hand, a number of fantastic claims about Pb  poi-
soning were proved to be without foundation.   The
remedy for this situation lies in more adequate
education.   Occupational medicine is given little
attention in most medical school curriculums.  The
author suggests greater use of audiovisual educa-
tion in plants,  medical schools, and medical
meetings, as an important factor in education.

batteries.  The workers spent mostly 3 hr/day at
filling operations and only occasionally and for
short periods in adjoining workshops containing the
above contaminants in excessive concentrations.
(Exposure to Pb ranged with ventilation from 0-60
yg and without ventilation, 80-404 yg/m3.  The MAC
is 0.15 mg/m3 air.)  In spite of high concentra-
tions of Pb and excessive evaporation of acids
above the tolerated values, no signs of poisoning
occurred except for deterioration of teeth by the
action of the acids.  The Pb in the blood of 5
workers ranged from 18-50 yg%, and in urine, 40-
58 ug/1; coproporphyrin in urine was 21.6-48 yg/1.
The authors state that the work in these plants
could be much safer if the hygienic conditions
were improved, and recommend periodic medical ex-
aminations and periodic control of hygienic condi-
tions.

        dustrial Health 14:92-5 (July), 1956.
Creosote pitch (known as CTF-200), a by-product of
the gas industry, is used as a liquid fuel because
of economic and other reasons, and ^800,000 tons
of it are used annually in Britain.  The ash is
small in amount but contains about 5% of Pb and
some As.  Boilers using this fuel are overhauled
yearly, and the men who clean the combustion
spaces and chambers are then exposed to massive
dust concentrations.  For some years the men have
been required to wear Mk IV or Microfilter respi-
rators.  The work reported in this paper was un-
dertaken in London to study the health hazards of
the cleaning.  In addition to chemical analysis of
the deposited dust, analysis of air samples taken
while work was in progress was carried out.  The
average concentration of Pb in the air varied from
50-200 mg/m3 which is many times as great as the
limit accepted in the US as safe for continual ex-
;josure.  Microscopic examinations of the particle
numbers and sizes of the dust were also made.  As
the men who carry out the boiler cleaning are only
engaged in this work for ^12 hr once every quar-
ter, the acute risk of Pb poisoning is small, but
respirators are clearly essential.  Analysis of
the urine of 6 men before, during and after a
cleaning operation indicated a distinct, though
not dangerous, Pb absorption.  This pointed to im-
perfect control of the Pb hazard.   This study led
to the opinion that no industrial filter-type
respirator is 100% efficient and that compressed-
air respirators, regularly tested for their fit,
should be introduced.

Clinical and environmental examinations were car-

content (measured in yg/m ) in the working posi-
tions was estimated as follows, respectively:
type casting, 19-88 and 4-6; monotype, 60-95 and
                10-13; type picking, 20-36 and 174; type setting,

                94 from the 1st and 105 from the 2nd showed some
                Pb absorption.  Absorption was more marked among

                properly distributed to import free machining
                properties.  The original manufacturer studied the
                Pb contamination problem  (Martin, 1939) , and a
                medical evaluation was also done (Kammer, 1941) .
                A similar process undertaken by the authors' com-
                pany led to this survey of the health risks in the
                operations which are described.
                  The results showed that atmospheric concentra-
                tions ranged  from 0.001-0.231 mg/m  when ventila-
                tion control was used; the same range was found
                at base-line analyses before process was initi-
                ated.  When adverse conditions existed, the range
                was from 0.01-2.J9 mg/m  .  A careful health in-
                ventory of all men who were engaged in any aspect

                making Pb steel included a medical history, physi-
                cal examination, routine  urinalysis, aerology,
                chest X ray, hemoglobin,  stippled erythrocyte
                count, qualitative coproporphyrin urine deter-
                mination and  quantitative blood Pb and urine Pb
                determinations.  These indicated that there has
                been no significant Pb absorption among the work-
                ers after >1  yr of exposure.  Blood Pb levels
                varied between 0.02-0.u5  mg/100 g of whole blood
                with a mean of 0.029, and urinary Pb  levels ranged
                between 0.02-0.13 mg/1 with a mean of 0.053.
                These data compare favorably with the industrial
                worker of the non-Pb trades.

                pheric samples showed Pb  to exceed the recom-
                mended value  of 0.15 mg/m^ in the area adjacent
                to the Pb pans.  The 2 major jobs there are the
                reelers and blockers.  Urine and blood analyses

 showed the reelers  to have  higher values.   Four-
 teen workers  were examined  in detail;  9 were
 found to suffer with anorexia,  headache,  joint
 fain, fatigue,  nausea and abdominal pain.
   forking conditions were improved by  emphasizing
 unique double exhaust hoods over Pb patenting
 furnaces, and by the use of Al shielding to re-
 duce the heat load.   As a result, urine and blood
 Pb levels of  employees dropped from higher than
 occupational  levels  to occupational levels, and
 there was an  improvement in the general health  of
 the workers along with an increase in  the  Hb and
 RBC.

 Two  processes used for decorative work involve
 high Pb  hazards:  in enameling,  where  Pb borate
 is  used  as  a  flux; and in "granlting"  where,  to
 obtain a rough  surface,  the  enamel  containing
 Pb  borate is  coarsely ground.   In the  enameling
 workshop of a glass  factory,  the  Pb content  in
 the  atmosphere  at different  places  varied  from
 0.08-0.15 mg/m  ,  at  one  site it  was as high as
 3.3  mg/m-'.  This  latter  one  was  eliminated.   An-
 other test  at the operation  when large pieces of
 glass were  processed,  showed Pb  levels of  0.160-
 1.210 mg/m  .  In the "graniting"  workroom  Pb con-
 centrations of  2.80-3.35 mg/m3  of air  were found.
 By  changes  in the process and ventilation  this
 level was reduced to 0.079-0.149  mg Pb/m  .   By
 analyzing the filter of  the  respirators of 4 work-
 men  in the  1st  shop  the  amount  of Pb which would
 have been inhaled, without protection,  in  the
 course of 8 hr was found to  be  7.3, 4.43,  2.6
 and  0.5  mg, respectively.   The  necessity of
 improvements  in  this  industry and the  possibility
 of  using Pb-free  enamel  is  stressed.

The author describes a process in a brass foundry
where  the man handling an alloy of Sn,  Cu and 27%
Pb at  1100°C,  in his breathing zone was exposed
 to 48 mg Pb/m  for a short period.  The process
was used only for 2  mo, and  no clinical or hema-
 tological evidence of Pb poisoning was found.
After  redesigning this apparatus  the Pb concen-
tration in air directly at the running extractor
was reduced to 20-30 mg/m ,  and in its immediate
vicinity  the Pb level was 0.22 mg/m3.  No Pb poi-
 soning was observed  in men engaged in this work.
  The German Railways consider as their prime
toxic hazard the manufacture of Pb bronze parti-
cles of respirable size.  Other Pb hazards are
incurred in tinning  processes in the hollow ware
industry.  In an old process white metal contain-
 ing 75% Pb  is used at such a low  temperature that
no risk from fumes is present although a certain
hazard arises from dross and dust.  However, be-
fore treatment with white metal the bearings are
tinned with a 50% Pb-Sn mixture which produces a
Pb level of 1.02 mg/m3 in the air over the tinning
pot while during the pouring of Pb into molds the
Pb concentration does not exceed 0.04 mg/m^.  In
another tinning process practiced in the Southern
Region, considerable amounts of fumes of Zn chlo-
ride, contaminated heavily with Pb, are produced.
The air over the tinning pot contained 1.8 mg
Pb/m3 on one occasion, but only 0.57 mg/m^ during
the process of wiping the joints.  The author be-
lieves that Pb poisoning in these cases does not
occur due to the intermittent nature of the work.

Ordinary washing did not remove Pb from the hands
of the workers satisfactorily, and scrubbing
with a 5% solution of acetic acid gave 10.6-77.7
mg Pb in the wash water, which amounted to 4.5-
68.9% of the Pb deposition on the hands.  Washing
with a warm solution of soda with abrasives, fol-
lowed by rinsing with a 1% solution of acetic
acid is recommended.  Three washings with a 3%
soda solution of the oral cavity of 8-15 workers
did not Contain Pb.  (From Referat. Zhur., Khim.

Air analyses in the working areas showed 14.2-85.5
mg Pb/m->, and the minimum concentration at any
point was $10 mg/m^.  Temperatures ranged in summer
from 13-30°, and in winter from 6-20°, and the

within short periods; the average rate of air move-
ment was 0.6 m/sec.   Measures to be taken for im-

Since Serbia is a country with numerous mines,
silicosis is one of  the most  common occupational
diseases.   The quartz content in ores and dust of
several metal and coal  mines were determined to
examine the degree of silicosis risk.   In 2 Pb-Zn
mines of 4 examined, the ore contained 35-42 and
2-12% quartz;  there  were 40.1 and 16.0% workers
suffering from silicosis (number examined,  106 and
382,  respectively).

Working conditions were studied in 65 plants with
377 laborers of whom 236 were completely exam-
ined.  The Pb content of the air of the working
environments was also studied.  The majority of
the workshops did not come up to reasonable hy-
gienic requirements, neither with regard to sani-
tary provisions nor in view of medical control
and attendance.  One third of the men showed high
Pb  levels of the blood (over 60 pg/100 ml), but
others with lower Pb levels also presented symp-
toms of intoxication.  Most affected were men
with >1 yr service  (40%).  The groups of laborers
most endangered were (in decreasing order): cast-
ers, molders, welders and melters.  No pathogno-
monic picture of the Pb  intoxication could be es-
tablished.  The dominant symptoms were the Pb
line, intestinal colics, metallic taste and con-
stipation.  As regards hematology only the number
of  red cells was found to be diminished, more
markedly in the more serious cases.  (From Ex-

After some important facts are given on toxicolo-
gy  and the possible forms of contact, locally or
generally, unnoticed or noticed, with different
poisons (direct contact with skin, inhalation,
effects on nose, pharynx, lungs, eyes, intes-
tines) the toxicity is discussed, on the basis
of  existing literature, of different binders and
their permissible concentrations, of pigments
(Pb, As, Hg, Cr, Sb, Mo, Cu, Ba, Cd, Zn, Se, Ir,
Ti, Co, Mn, and organic groups containing cyanide
or  cyanamide groups), of driers, solvents, dilu-
ents, and plasticizers based on their physical-
chemical properties (prickling of skin, tearing
of eyes,  chronic conjunctivitis, sneezing, cough-
ing), and on their chemical structure (narcotic,
blindness, fatal attack on blood-forming organs,
etc).  A systematic hematological investigation
is described.   The work was carried out to enable
dermatologists to test skin diseases by contact
with the substances tested in these experiments.

The recommended maximum atmospheric concentration
of  Pb, on the basis of human experience, is list-
ed  as 0.2 mg/m3 for 8-hr exposure.  Symptoms and
signs of Pb poisoning are described.  It is noted
that the Subcommittee on Lead of the Z37 Section-

tion has recommended the adoption of 0.5 mg Pb/m^
                as the maximum acceptable atmosphere concentra-
                tion for Pb chromate and sulfide, and 0.2 mg/m3

                This report, presented at a meeting of the Swiss
                Society of Industrial Medicine and Accidents, is
                concerned only with industries of various kinds
                in Switzerland in which there may be a danger to
                health of the workers from exposure to Pb.  These
                industries are described and an account is given
                of the results of investigations which have been
                carried out in each case but with stress on the
                point that every separate factory in each indus-
                try must be separately considered because of the
                variations in such factors as hygienic state,
                degree of ventilation and the human factor which
                may have a determining effect on the occurrence
                of Pb intoxication.  The methods employed in air
                analyses are described with a statement of opin-
                ions on the permissible limits of Pb concentra-
                tion in the air of factories.  The processes in
                different industries where Pb may be a risk are
                considered at some length with an account of the
                conditions which were found on inspection of indi-
                vidual factories.  The industries which have been
                studied are:  the manufacture of accumulators,

 tics in which Pb-containing  stabilizers  are  used,
 pottery work, some types  of  enamelling,  printing,
 manufacture of  telephone  cables  sheathed in  Pb,
 and  chemical  and  other works.  Emphasis  is laid
 on the point  that  accurate scientific and other
 investigations  are essential before the  best pos-
 sible control and  prevention of  Pb poisoning can
 be achieved.  (From Bulletin of  Hygiene  34:58,

 A  study was made in a  small  powder metallurgical
 plant in which  collected  air containing  metallic
 Pb dust of extremely small particle size was re-
 circulated.  Although  Pb  was present  in  small
 amounts (6% maximum) in the  materials used,  the
 survey revealed excessive amounts  of  Pb  in the
 returned air from unit collectors  and in the at-
 mosphere (0.06-0.90 mg/m  ) as well as high levels
 in the urines of exposed  workers.   For 14 employ-
 ees  a urinary Pb excretion ranging from  225-471
 pg/1 was found.  After control of  the exhaust
 ventilation and other  precautionary measures the
 Pb level in air was reduced  to 0.04-0.15 mg/m^
 and  the urinary Pb  excretion of  the same 14  em-
 ployees dropped to  25-235

A Pb  exposure hazard  in a  metal-burnishing opera-
tion  peculiar to the  silversmithing industry was
investigated, following the illness of one of the
workers who upon return to work was found to ex-
crete elevated  amounts of  Pb and  coproporphyrins
(CP) .  The extent of  contamination was found to
be  dependent upon the amount of sandbobbing  per-
formed.   The range of Pb contamination varied
from  3.2% for pumice  used  half a  workday to  8.5%
for pumice used for a week.  Air  analyses before
ventilation showed 1.00-17.00 mg  Pb/10 m-*.   Urine
analyses  of the sandbobbers for mg Pb/1  and  mg
CP/1  gave the following results:  before ventila-
tion  0.10-0.67, 0.10-4.4;  after ventilation  0.07-
0.17, 0.2-1.1.

concentrations measured were well below  the
threshold limit of 2.0 mg  Pb/10 m3, and  only 2
exceeded it (1 during a dressing  operation and

The half-mask 78 is said to be a  protection
against coarse dust as well as harmful fine dust
which may enter the lungs.  It is also useful as
a protection against dangerous metal fumes, such
as Pb fumes.  ihe mask which is made from neo-
prene, has the properties of soft rubber and is
not attacked by cleaning or disinfecting agents.
Its good fit is emphasized.  The mask has 2 vents
for exhaling as most DrBger models have.  The
ring filter (742 St) consists only of the filter
material without aetal or synthetic parts and is
therefore very cheap.  The mask is available in
3 sizes.  (From author's summary; Zentralblatt

        32, No. 14:368-77, 1958.
In a paper presented at the SA Medical Congress,
Durban, September 1957, the author gives a survey
of the industrial hazard of Pb intoxication in the
growing industrialization of SA.  Topics discussed
are the environment of industrial workers, plant
inspection, and enumeration of the SA industries
using Pb, atmospheric contamination by dust and
fumes and its diminution by protective measures,
instruction of workers, establishment of maximum
allowable limits and air sampling methods for its
control.  Other ways of reducing  the Pb hazard in
manufacture are modification of industrial opera-
tions, plant design, isolation of hazardous opera-
tions, ventilation, etc.  Measures directed to the
individual workman include personal protective
equipment, showering and sanitary facilities, pro-
hibition of eating in workrooms and with contami-
nated hands, and special safety measures in the
handling of TEL.   Medical considerations are sex
and age of worker, examination of each worker upon
resumption of employment, and individual and family
susceptibility and acquired tolerance.  Conditions
meriting rejection for Pb work and periodic ex-
aminations of Pb workers (frequency according
to UK Factory Act regulations) are given.  The
survey ends with a detailed description from the
literature of signs and symptoms of Pb-induced
disturbances such as gastrointestinal symptoms,
nervous system signs, arthralgla and renal disease.
Pallor and the Pb or Burton lines are signs of
special significance.  Absorption and excretion
of Pb, effects of increased Pb exposure, or stip-
pling of erythrocytes, white cell count, porphyrin
tests, Hb estimation and general managements and
disposal of cases of absorption as well as prophy-
lactic methods are among the subjects treated in
the survey.

through 2 Petri bottles filled with H2S04 94% at
18-20° and then through 2 containers 0.5% filled
with a solution of iodine in 1% KI for the catch-
ing of the TEL fumes not absorbed by the sulfuric
acid.  When the treated H2S04 is diluted 1:1 with
water a white sediment of Pb sulfate precipitates
out of the solution.  The degree of TEL absorption
with various quantities of these fumes in the air
is tabulated.  The H2S04 concentration should be
>79.6%.  The activity of H2S04 as absorber of TEL
fumes significantly increases with the raising of
temperature to 100°.  The destruction of 1 g of
TEL requires 0.31 g of monohydrate.  (From Chemi-

Typical causes of accidents are (1) removal of
breathing equipment, (2) absorption of vapor out-
side tank, (3) wrong materials for protective
equipment and (4) unsuitable breathing equipment.
regulations concerning entry after cleaning are
revised and stringent minimum conditions are set
up.  Breathing bags are not generally recommended,
particularly not in warmer weather.  Proper air
extractors should be provided for ventilation.
Manufacturers of tanks should be required to in-
corporate in their design at least one clean-out
sump and existing tanks should be modified to
provide such sumps.

New data on the effect of harmful air pollutant
concentrations have been collected by research
institutes during the last years, leading to an
extension of the list of standardized harmful air
admixtures, and a revision of the MAC's for air
pollutants.  At the Jubilee session of the Insti-
tute of Hygiene and Occupational Diseases, AMS,
USSR (1953) the question was raised to change to
the particle-count method, used widely abroad.
Attempts, however, to compare dust counts with the
morbidity rate among workers showed no clear con-
nection.  The author states that the method is so
widely used abroad and stems from its simplicity
rather than its reliability.
  So far, no clear and uncontestable data have
been presented to establish safe threshold limits
                of  aerosol inhalation, because  the methods used
                still  lack the precision.  Data obtained  from  the
                health conditions of  the workers  cannot be used  as
                criteria.  For toxic  suspended  aerosols MAC's  must
                be  arrived at experimentally without  delay; how-
                ever,  these should be regarded  as tentative, and
                subject to revision on the basis  of further clini-
                cal observations and  supplemented experiments.
                  It has not been possible yet  to verify  the
                necessity of establishing separate norms  for maxi-
                mum and mean work-day concentrations, because  most
                methods enable the determination  of average con-
                centration only for a prolonged time  lapse.  De-
                spite  these limitations, data have been accumula-
                ted and a list of 34  aerosols was presented at the
                1957 symposium on pneumoconiosis  in Moscow.  The
                list published by the Scientific Medical  Council
                of  Ministry of Health USSR, contains  29 mineral
                and organic dusts and 26 aerosols of  metals,
                metalloids and their  compounds;  for Pb and its in-
                organic compounds, 0.01 mg/m3 was set as  the MAC.
                Departure from the set values can be  made with the
                permission of the State Sanitary  Inspection where
                workers remain a short time only  on the site.  Ad-
                ditions to the list could be introduced within the
                next 3-4 yr.
                  Prime attention is  urged for  the development of
                methods for the study of aerosols and their prop-
                erty and their effect on the organism, as well as
                the need for more rigid limits  for the density in
                suspended dust particles <2y in diameter.  While
                conducting hygienic research, the author  advocates
                that determination of dust dispersion according  to
                particle diameter be  made mandatory.  Several
                research methods are  mentioned  which  should be
                used as more positive bases for the determination
                of  new MAC levels.

                tion in air obtained  in 1959 are  compared with the
                results in 1949.  In  general all  the  results were
                10-200 times above the permissible concentration
                limits,  and compared  with the results obtained in
                1949 a general increase of the  number of  high
                (14-30 mg/m ) results was established.  Various
                improvements of working conditions are advised.

                Among  the various types of welding performed is
                that of Pb burning which is becoming  more popular
                in  shipyards with the advent of nuclear-powered
                ships.   The Pb concentration in air during this
                operation is low because the temperature  needed
                is  only slightly above the melting point; in 1

 plates primed with red  Pb  primer  and/or Zn chro-
 mate  showed that a Pb hazard  exists whenever the
 operation  is carried out in confined spaces.
 Concentrations in  air collected  in  numerous work
 rooms with or without ventilation ranged from
 0-6.9 mg/m .  The  urinary  Pb  level  in  30 welders
 or burners was O.u2-0.12 mg/1.

        SPRAY PAINTING  WITHOUT COMPRESSED  AIR.
        Archives of  Environmental Health 1:534-9
         (Dec.), 1960.
 The study was designed  to  indicate  the health,
 safety, and fire hazards associated with the use
 of  hydraulic  pressure alone ("high-pressure" meth-
 od) and hydraulic  pressure and heating the  paint
 to reduce  the viscosity ("heat-wlth-pressure"
 method).  The primary objective was to determine
 whether an  air  velocity <150  ft/min could  be safely
 applied in  the ventilation control  of spray booths,
 the extent  of  the  health hazard being based on the
 concentration in the breathing zone of mist con-
 taining Pb  or Zn chromate  pigment and vapor from
the thinner.  All spraying was done by representa-
tives of the vendors who supplied their own paint-
ing and respiratory protective equipment.  No med-
ical records were available for them.
  The following paint samples were analyzed:  Rust-
inhibiting enamel (Pb positive, specification pre-
scribes pigment containing 35% Pb chromate and 17%
red Pb); Zn chromate primer; synthetic thinner,
and rust-inhibiting enamel used on missiles.  The
results showed that in vehicle spraying, Pb-bearing
paint by the heat-with-pressure method produced
concentrations averaging 4.4 mg/m3 at low air ve-
locity, av 0.5 mg/m3 at intermediate, and av 2.5
mg/m-' when the high-pressure method was used at
intermediate air velocity, but 3.5 mg/m3 at high
air velocity.  In missile container spraying, Pb-
paint spraying by heat-with-pressure method gave
average concentrations of 3.3 mg/m3 at intermediate
velocity, and by high-pressure method, av 2.3 mg/
m3 at low velocity.  Spraying parts by heat-with-
pressure method gave nil concentration at 150 fpm
air velocity and 1.1 mg/m3 at 100-110 fpm; at 72
fpm, Pb concentration was >1.1 mg/m3 .  No samples
were obtained for the high-pressure method.  In
open shop vehicle spraying, the heat-with-pressure
method gave av 5.9 mg/m3, and 3.2 mg/m3 by the
high-pressure method.  Solvent vapor concentra-
tions averaged 800 and 590 ppm by these 2 methods,
respectively.  In the other applications, solvent
vapors were below the MAC of 500 ppm.
  The author concludes that at low rates of venti-
lation in vehicle spraying, personnel requires
protection of paint-spray respirators, and at air
velocities <100-110 fpm dangerous concentrations
of explosive vapors are recorded.  For missile
container spraying, a ventilating rate of at least
150 fpm and higher when bottom sides are sprayed
is required.  In open-face booths, a ventilating
rate of at least 150 fpm should be maintained.
Results in open shop area indicate danger from
every standpoint.

A study was made of the Pb quantity found on the
hands of automobile drivers, garage workers, auto
repair shop workers, etc.  The washings  (done with
TEL-free gasoline B-70) from workers' hands, steer-
ing wheels and car surfaces were obtained at noon
and the end of the day.  The results showed that
3.6% of the drivers' and 4% of other workers' hands
were TEL-free; no TEL-free cases were found among
the 50 workers in the aviation industry.  The av-
erage amount found on drivers' hands was 0.125 mg
and 0.115 on the hands of garage and repair shop
workers.  In the aviation workers this amounted to
0.249 mg, caused by the fact that aviation gasoline

contains 2-3 times as much TEL as ordinary gas.
On 89% of the steering wheels tested the amount
found ranged between 0.1-0.2 mg and it was =0,3 mg
in 11%.  The same amounts were found on the outside
surfaces of cars, hand-operated transmission parts
and handles.  Amounts of 0.4-0.5 mg were found in
airplane cabins, and the washings of service per-
sonnel contained 0.3 mg TEL.  Considerable amounts
of TEL present on the handwashings of workers
not having direct contact with TEL were also found.
Contamination of hands and other parts of the body
proved not to be eliminated or reduced in spite of
instructions regarding personal hygiene, etc.  The
authors conclude that chronic TEL poisoning appears
a possibility and that strict observation of in-
structions and education of the workers involved
are the only effective protective means.

ii survey was made of the pottery industry in
Stoke-on-Trent between 1956 and 1958 by the Fac-
tory Inspectorate of the Ministry of Labour and
National Health and a report was published in
June 1959.   Attention is focused on the control
of Pb poisoning which has occurred progressively
over the last 50 yr.  However, no vital statis-
tics of the workers nor indices of general health
and of occupational and non-occupational diseases
were given,   i'he Minister referred the report to
the Joint Standing Committee of the Pottery In-
dustry for further action and recommendations.
The author points out that complacency about Pb
poisoning and Pb absorption in the pottery indus-
try should be shaken by the occurrence of 2 cases
listed in the Annual Report of H.II. Chief Inspec-
tor of Factories for 1958 which clearly indicates
the need of an industrial health service.

Samples of the air were taken in 127 working
places in 32 printing plants of the People's Re-
public of Croatia, Yugoslavia.  It was found that
in 22 working places Pb concentration in the air
was higher than the MAC (0.15 mg/m3) .  The ranges
observed were from 0.15-2.0 pg/m3.  This observa-
tion is in contradiction with the general opinion
that occupational Pb poisoning in printing plants
is practically impossible.

        GALVANIZED AND ZINC-SILICATE COATED
        STEELS.   American Industrial Hygiene Asso-

An investigation was made to determine whether or
not welding and cutting operations on steel with
inorganic coatings consisting of Zn-s>ilicate or
galvanizing could give rise to hazardous amounts
of Pb and Zn fumes.   The sampling took place in a
pipe welding and a structural shop, both equipped
with large doors and excellent ventilation.  Other
samples were collected in a tarpaulin enclosure to
                 demonstrate maximum  fume  concentration  in a  con-
                 fined area.  Collection was on Whatman  No. 42 fil-
                 ter papers, either 1-20 ft above welding or  at
                 breathing level  in which  case a polyethylene tube,
                 3  ft long was attached to the filter holder  and
                 inserted into the welder's hood.  Pb was deter-
                 mined colorimetrically by an adaptation of the
                 ACGIH method.  Results showed that at the welder's
                 breathing level  such welding or cutting opera-
                 tions on Zn-silicate coated steel in poorly  ven-
                 tilated areas gave rise to fumes containing  4-75
                 times the MAC of Pb, and  1-14 times that of  Zn.
                 At that level, the ZnO fumes amounted to 199.4
                 mg/m  and at 1-3 ft  above welding, av 119.9  for
                 electric arc welding and  av 26.81 for oxyacetylene
                 welding.  The corresponding figures for Pb were
                 5.16, 5.63 and 1.96  mg/m3, respectively.  The same
                 operations on galvanized  steel under similar con-
                 ditions produced fumes containing 2-4 times  the
                 MAC of Pb, and 3-12  times the MAC of Zn.  At
                 breathing level, electric arc welding generated
                 185.0 mg/m3 ZnO  and  an av of 108.5 at 2-6 ft above
                 welding and oxyacetylene welding at the latter
                 heights av 63.72.  The corresponding Pb values
                 were 0.64, 0.52, and 0.43 mg/m3.  Clean steel
                 showed no Pb and only 14.9 and 1.3 mg/m3 at  2 and
                 20 ft above welding.  When ventilation  was ade-
                 quate, the MAC was not greatly or consistently ex-
                 ceeded for either type of metal coating.  Pb
                 ranged from 0.01-0.18 mg/m3, and ZnO, 6.63-19.81.
                 Welding outdoors, with a  10 mi/hr breeze during
                 sampling, with welder sitting upwind, showed no
                 Pb when probe was held 3  in. from nose,  and 0.01
                 and 0.06 mg/m  with  probe in hood.  The corre-
                 sponding ZnO levels  were  2.40, 4.22 and 13.24
                 mg/m3.
                   The author recommends that the American Standard
                 Z-49.1, 1958 be  followed.

 The  report of a study  of  the working conditions at
 several  mines and  concentration  installations of
 nonferrous and rare metal ores  (Pb, Sn, Mo, Ta,
 Nb,  etc) deals entirely with radioactive exposure.
 Special  attention was  paid  to the  composition of
 air  contaminants,  the  degree of  contamination of
 hands,  overalls of  the workers  and various equip-
 ment surfaces.  The conclusion was that external
 radiation  had no  essential  significance; however,
 the  author stresses that  the possibility of the
 combined effect of  silica,  radioactive  and toxic
 substances (Pb, Sn, Ta, Nb, etc) should be kept
 in mind.

 In a Pb  accumulator plant, the dust collecting
 equipment had caught fire twice without any ap-
 parent reason.  Similar accidents had been re-
 ^orted also from other Pb plants.  The conclusion
was  drawn that self-ignition occurs from the heat
which is released when the Pb particles deposited
 in the filters dry out and oxidize.  Various fi-
bers  are discussed as replacement for the cotton
 filters.

 The  widespread use of  Cu for waterlines, gaslines
and some drain lines has increased the hazard of
Pb poisoning, since large quantities of Pb are
melted and poured to seal joints in waste lines
to solder sections of  Cu pipe.  The advent of
gasoline-powered machines has created additional
exposures to noise as  well as to CO and other
products of combustion.

The effect of handwashing on the removal of Pb
from the hands of Pb workers was studied with 3%
acetic acid solution,  ordinary soap solution and
tap water.  After handwashing the Pb content was
estimated in each solution by a dithizone polaro-
graphic method.  No significant differences were
found among the 3 solutions in their ability to
remove Pb.  Handwashing with a brush, using any
available solution, seemed to be effective in re-
moving Pb from the hands of the workers.  (From

A survey of 5 printing works in Milan showed that
Pb concentrations in air were well below the MAC,
but values in the type drawer dust were high (av
25.7-32.2 pg/m  in air at various operations
where exhausts were operating, and 65-180 when
not; in drawers, av 26.5%, and in settled dust,
1.4%).  The maximum Pb amount found on the hands
of some hand-compositors was 8 mg.   Clinical and
laboratory examinations of 100 workers showed no
abnormal Pb absorption, and the case histories of
127 hospitalized workers revealed only 2 cases of
mild saturnism and 5 cases of increased Pb absorp-
tion.  (20 references)

Experiments conducted in 1956 in Pb foundries
have shown that in most cases tested, chelating
agents produced a decrease in Pb absorption.  Cer-
tain difficulties have been encountered due to
the lack of a suitable method for an easy deter-
mination of Pb absorption.  (From Zentralblatt

Filters remove 95% of the Pb dust in the air.
The most effective cloth for the filters is ker-
sey 4112 or 4114 which, due to the absence of
nap, is well suited for retaining dust.  The
breaking strength of kersey is 3-4 times that of
wool.  Uet dust catchers, with an 85-90% degree
of purification, are used in those areas in which
cloth filter cannot be used due to acid or water
vapor, or due to the danger of fire from sparks.

Studies made in several repair garages of the
State have revealed numerous unhealthful condi-
tions and practices to the attention of garage
operators and indicate what means may be employed
to minimize or eliminate them.  In addition to
hazards from CO, those from spray painting,  with
particular emphasis on exposure to solvent vapors
and Pb are discussed.  In body repair work the in-
halation of toxic metal fumes or dust represents
a real hazard.  Caution must also be exercised in
handling TEL-containing gasoline.  Adequate wash-
ing and toilet facilities should be provided for
the employees and their attention drawn to per-
sonal hygiene.  Washing of hands should not be
done with gasoline or other similar solvents.

the American Conference of Government Hygienists,
is used as a basis for calculating maximum con-
centrations for work of intermittent nature.

                The environmental hazard of Pb dust resulting from
                the use of firearms in indoor firing ranges is
                discussed.   For the efficient control of Pb dust,
                a minimum ventilation rate of 50 cfm/ft^ of open
                oross sectional area at the firing line is satis-
                factory, with a minimum acceptable rate of 20 cfm.
                All cleaning operations should be performed with
                the ventilation system in operation.  For clean-
                ing and repairing the bullet trap, the use of a
                respirator is recommended.  Airborne Pb concen-
                trations measured at a conventional firing range
                were 0.19-0.63 mg/m-* when the ventilation was on,
                and 1.18-3.77 mg/m  when the ventilation was off.
                in a private basement range with no ventilation
                airborne Pb  concentrations ranged from 0.64-1.12.
                The MAC for  Pb, based on an 8-hr working day, is
                0.15 mg/m .  A scheme illustrating the ventilation
                recommended  in designing indoor firing ranges is
                included.

                The author had observed that workers in Pb refining
                plants had considerable deposits of Pb sulfate dust
                on their skin, even though at breathing level the
                concentrations were within MAC levels.  For this
                reason they  undertook the analysis of the  hand
                washwater of workers  (using 1% HC1 solution in
                100 ml water); 979 samples were analyzed for vari-
                ous processes from flotation, filtration,  typo-
                graphic and  crushing  operations.  The average in-
                dices of contamination ranged from 49.95 mg% for
                filtration down to 2.64 for crushing operations.
                Concentrations found  at the end of the work day
                and arrival  at work were  tabulated.  The results
                showed that  the flotation, filtration and  techni-
                cal control  operations gave rise to greatest con-
                tamination of the  skin.

An  operator had changed a  still from  secondary to
regular distillation which meant that pressure
would reduce from 2 psig to atmospheric.   i'he op-
erator had noticed a small leak and was  standing
on  a step below a still manhole when  a 6-in.in-
spection port cover which  he was attempting  to
tighten blew off allowing  a mixture of steam, hot
water, TEL, and sludge to  gush out onto  him.
  The manhole port cover had not been tightened
properly and therefore the company decided to re-
train employees in the proper method  of  tightening
manhole port covers.

On the basis of their 9-yr experience in the medi-
cal  department of a large automobile plant, the
authors describe in some detail the hazards en-
countered in workshops during the metal-spray
coating, filing and scarfing of Pb and Sn alloys.
The dusts generated ranged in size from 1-5 u,
with 65% in the 1-2 y range.   In view of the con-
ditions encountered,  they recommended a number of
preventive measures which included sanitary facil-
ities,  forbidding smoking and eating in the work-
shops,  personal hygiene and protection, continu-
ous  control of atmospheric conditions, good house-
Beeping, medical supervision, and periodic rota-
tion of workers at greatest risk.  They illus-
trate the results of the preventive program by
tabulating the subjective and objective symptoms
in a group of 75 workers before the measures were
instituted and in 70 workers over a period of 8
mo after these measures went into effect.  Both
groups were between 20 and 28 yr old, who had
entered their jobs in good health.  In the 1st
group,  complaints of asthenia were voiced by 70%
vs by 32% of the 2nd group; diminished appetite
and  gastrointestinal disorders were indicated by
from 28-86% vs 14-48%; nervousness by 10 vs 4%;
Pb gum line was seen in 21 vs 7%; decreased eryth-
rocytes in 61 vs 20%;  basophilic stippling in 80
vs 33%;  increased coproporphyrinuria in  70 vs 32%;
cases who had to be removed from exposure, 60 vs
19%.

The authors discuss the legal regulations related
to Pb poisoning, mention the contraindications for
work in contact with Pb, and stress the importance
of medical examination before employment as well
as that of periodic examinations.  The measures of
technical and individual protection are outlined
and recommendations are set forth for the intro-
duction of concrete measures for the prevention of
contamination of the working environment by Pb.
Although prophylactic treatment with C32EDTA is
restricted to "epidemics" of poisoning, etc, and
will probably remain at this level, unless new
investigations prove the contrary, the authors
describe their attempt of such treatment.  In
closing they stress health education of the Pb
exposed workers.   (From authors' summary)

The concentration of TEL vapors in the atmosphere
decreased but still exceeded the permissible limit

Significant properties,  hygienic standards, indus-

reviewed,  i'he recommended MAC of TEL for 8-hr  ex-
posure is given as 0.075 mg  as Pb/m  of air.  This
recommendation is based on animal studies and hu-
man experience.  Signs and symptoms of effects
from exposure to TEL are discussed.  For exposure
of a few days' duration at infrequently repeated
intervals a maximum concentration of 0.15 mg as
Pb/m  is permitted.  The atmospheric concentration
immediately hazardous to life is not known.  A
concentration of ^100 mg Pb/m^ of air for 1 hr is
capable of producing illness but is not necessar-
ily nor probably fatal.   As  a rough guide, urinary
Pb excretion >O.I1 mg/1 suggests that exposure is
above normal, at 0.15 mg/1 the person should be
moved to an area of less exposure and at 0.20 mg/1
the employee should be removed from all exposure.

pointed out.  On a routine highway bridge mainte-
nance job involving sand blasting of the painted
steel structures, the Pb content ranged from 6-116
mg/m  in air samples and from 117-285 millions of
particles/ft  of air in the dust.  Protective de-
vices and education and medical supervision of the
workers are discussed, together with education of
the workers and encouragement of personal hygiene.
Work control procedures are suggested.

When a 60-yr-old steel bridge, in Minnesota, coated
many times with Pb paint,  was dismantled, the
structural members were cut into sections with an
acetylene torch.  Four air samples collected at
the operator's breathing level contained 0.4-0.9
mg Pb/m^ and 4 other samples, obtained 2-3 ft
downwind from the point of cutting, 0.2-0.5 mg/m^.
Four men were occupied with cutting half time for
3 mo; one of them was hospitalized after the pro-
ject was completed.

The authors show that in Romania,  as in all so-
cialist countries, non-toxic and  safe working con-
ditions were created due to the care of the state
for the health of the working people, to the in-
troduction of new technical equipment,  and to
mechanization, automation and the fact that pro-
duction in the petroleum industry takes place in
well-sealed machinery.  Thus, the risk of any re-
appearance of professional diseases in this impor-
tant field of the national economy of Romania will
continue to diminish.  To  substantiate scientifi-
cally the complex measures covering the welfare of
the working people and the control of professional
diseases,  the continuous reduction of morbidity
involving temporary disability, and the increase
of the ability to work, a number  of research in-
stitutes in the field of industrial hygiene and
of occupational diseases were established.   In the
laboratories where antiknock agents were tested,
the workers were protected against Pb poisoning
by wearing a mask and special rubber clothing.
The precautions taken against other hazards (gaso-
line, olefins, Hg, sulfur dioxide, furfurol, phe-
nols, cresols, chlorine, dermatitis) were out-
lined.

A study was made of the methods of absolute de-
contamination due to the large amounts of Pb pro-
tection used in nuclear industry.   Decontamination
                 by sand  blasting  or  by steam was  replaced  with a
                 decontamination of  the Pb by fusion.   Decontamina-

 A  strict surveillance has been established in Bul-
 garia  in plants  manufacturing  Pb storage batter-
 ies.   All work places must be  furnished with effi-
 cient  ventilation and the workers exposed  to va-
 pors and dust  must wear masks.  In  all workshops
 where  there is contact with Pb, the floors must be
 kept moist.  Personal hygiene  and good nutrition
 for  the workers  are  emphasized.  By observing rig-
 orous  hygienic and sanitary measures, the  inci-
 dence  of Pb poisoning has been markedly reduced in
 the  last years.

In their introduction,  the authors  state that
 thanks to varied and rich natural resources, the
chemical industry holds an important place  in the
national industrial program.   Large combines are
presently being built where  the most modern  tech-
nological processes will be  incorporated.  In  the
past,  the protection of workers in  industries  had
been greatly neglected; there were  no medical
facilities in  the plants, occupational diseases
were little known, and systematic research was
nonexistent.   Such research  was begun in 1949,
assisted by the work and rich experience of  Soviet
scientists.  Research in Romania has been oriented
toward  the study of the complex problems of  the
work environment and the study of the general  oc-
cupational morbidity and industrial accidents.  The
health  hazards in the various industries, ie,
pesticides, plastics, petroleum products, etc,
including those with exposure to Pb and what is
being done about them, is discussed.

Working conditions in the Pb-uxtracting industry
have been greatly improved during the last 12 yr.
Compared with concentrations of Pb found in the
atmosphere in 1950, an average reduction of 92.46%
has been effected by 1962.   In most places it is
close to the maximum permissible concentration of
Pb in air.

the production of leaded steel is described.
Hoods constructed of 16 gauge steel are used for
exhaust ventilation of Pb fumes from open top- and
sunk head moulds.  To determine the effectiveness
of the engineering control measures, a biochemical
testing program was established.  All 178 workers,
who might be involved in any aspect of pouring Pb-
steel ingots submitted urine specimens for Pb
analysis.   Mean urinary levels of Pb (mg/1)  were
as follows for base levels;  at 3 mo, 9 mo, and 15
mo of exposure with number of men shown in paren-
theses:  (178)  0.036;  (11)  0.035;  (29) 0.050; (23)
0.045.   The test results demonstrated that the
urine levels have remained fairly stable despite a
3.J fold increase in the production of steel.

The operations and conditions of work in the re-
modeling of ships were examined.  These involved
demolition, removal of old paint, etc.  The type
of protection offered (respirators, etc) was also
noted.  Paint removal, metal cutting and electri-
cal welding were accompanied by large amounts of
dust containing Pb.  Of 88 samples, only 13
showed no Pb; 0.01-0.12 mg Pb/cm' of surface dust
was found.  Hand washwater was also analyzed for
Pb; in some operations it ranged up to 0.008 mg/
cm^ skin.  Recommendations are made for improve-
ment of working conditions.

       DATA  SHEET.  New York, PSD  2202, Jan.
       1964,  4 pp.
The data sheet outlines precautions for the pre-
vention of hazardous  exposure of personnel  to  Pb
antiknock compounds while dismantling tanks that
have contained Pb gasoline, and for the disposal
of the steel.  The 1st step, before dismantling
work begins,  is to clean the tank in accordance
with recommended practices set forth in API Bulle-
tin 2016 "Cleaning Tanks Used for Gasoline  or
Similar Low-Flash Products."  The dismantling pro-
cedure, especially during cold-cutting or sand-
blasting operations,  will dislodge accumulated
scale and rust; the resulting dust can be reduced
uy application of water spray or fog.  Precautions
must be taken as leakage may have exposed the in-
side of the pontoons  to Pb gasoline.  iJuring chip-
ping and cold-cutting, all men within the tank
should wear toxic-dust respirators.  Workmen
should wash hands and face before eating and
shower at the end of  each working day.  During
flame-cutting, each worker should wear a hose mask
through which fresh air is supplied; sandblasters
should wear sandblasters' helmets.
  If the exterior of  the tank has been primed or
painted with Pb-base  paint, flame-cutting from out-
side the tank requires the wearing of an approved
toxic-metal-fumes respirator.  If the steel is to
be sold for scrap or  remelting,  all interior sur-
faces should be sandblasted or wire-brushed to bare
metal.  Plates and parts which have been in contact
with Pb gasoline must not be reused for the manu-
facture of containers for edible products for
either animal or human consumption.  Any wood which
has been saturated by Pb gasoline should be dis-
posed of by burning but should not be burned in
stoves or fireplaces  of structures for human habi-
tation.

                 The high incidence of Pb poisoning seen  in Italy
                 and other countries in storage battery plants is
                 due to continual risk of exposure in all phases of
                 work to Pb in the form of dust, fumes  and vapors.
                 For an evaluation of the actual risks  involved,
                 and of the efficiency of protective measures, the
                 author examined the conditions in a plant manufac-
                 turing an av of 12,000 batteries/mo and  employing
                 ^80 workers.  Aside from analyzing the atmospheric
                 concentrations of Pb encountered in the  various
                 operations which are described in some detail,
                 clinical and laboratory tests were performed on
                 the workers exposed to Pb.  The first  operation
                 described is that of fusing metallic and antimo-
                 nial Pb, then casting it in molds to make the
                 grates,  with exhaust fans functioning,  the atmo-
                 spheric concentration of Pb was 0.67 mg/m^ close
                 to the molds and 0.22 at 1-m distance; the  corre-
                 sponding concentrations without exhaust  were 0.83
                 and 0.54, respectively; and at a greater dis-
                 tance,  0.09-0.27 (av 0.13).  Other operations were
                 accompanied by concentrations of Pb as high as 2.4
                 mg/m .
                   The mean concentrations of Pb found  in the urine
                 of workers varied from 128-320 Mg/24 hr  (with a
                 range up to 480), the highest being found in sol-
                 derers  of plates, followed closely by  workers
                 pouring the Pb "by hand" into molds.  Coproporphy-
                 rins (CP)/24-hr urine were a mean of 102-184 ug,
                 ranging up to 250.   The 2 operations mentioned
                 above were not adequately safeguarded, in fact
                 soldering was done without benefit of  exhaust
                 fans.   In the other 2 operations described, the
                 potential risk was quite high; however,  the uri-
                 nary Pb and CP were only little higher than nor-
                 mal.   No signs of Pb poisoning were seen in the
                 workmen.  The findings most frequently encountered
                 involved the respiratory and gastroenteric system,
                 with a prevalence of gastroduodenitis  and subjec-
                 tive signs of hepatic insufficiency.  These were
                 defined by the author as ailments most often seen
                 in the working population and not attributable to
                 exposure to Pb.
                   The recommendations for controlling  the hazards
                 included the lowering of the temperature at which
                 the metal was fused to prevent the liberation of
                 Pb vapors; the substitution of "hand"  operations
                 by automated or semi-automated systems;  adequate
                 exhausts; personal protection and hygiene (prohi-
                 bition of eating in the shops, washing hands, etc),
                 and periodic examinations.

The amounts of sulfur dioxide and Pb dust emitted
from a Pb smelting factory were investigated both
from an economic and health point of view.  It was
found that on an av >75,000 ft3 of S02 and ^2000
Ib Pb as dust are thrown daily into  the  surround-
ing atmosphere.  The particle size of the flue
dust is very small, practically all particles are
<1 vi.  Within the factory, dust collected at 5
sites by MSA Midget Impinger gave Pb concentra-
tions of 5.65-11.29 mg/m3 air.  The Pb content of
fume samples collected by electrostatic  sampler
showed 18.71-119.6 mg/m3 air drawn.  Pb  exposure
of the factory workers was determined in 16 se-
lected subjects, 28-44 yr old and employed for
6-18 yr.  Urinary Pb excretion was found to vary
from 0.04-0.85 mg/1, with only 4 values  <0.08
(normal).  The authors conclude that the dust,
fume and gas problem is one that requires immedi-
ate attention.  It could be substantially improved
by recovery of the waste materials, and  this will
automatically help solve the health problem.

        Gigiena 1 Sanitariya 29:33-7 (Feb.), 1964.
Dust control measures instituted in the  past num-
uer of years in the Kirghizia mines included wet
drilling, wetting down of the rails and  mounds of
ore before and during loading onto dump  trucks.
The Pb ores, obtained from shaft and open-pit
mines are beneficiated by the flotation  process,
requiring crushing and loading onto various con-
veyors and crushers before final loading into ball
mills, whereupon no further dust hazard  exists.
For the evaluation of exposure to dusts, 5826 at-
mospheric samples collected at various places of
the 5 mines under investigation were analyzed and
the results are shown for the years 1955 through
1962.  The free silica content of the dust ranged
from 22.2-40.6% with the exception of 1  mine,
which showed 4.5%.  Particle size up to  5 y pre-
vailed in all.  The dust content ranged  from an
average of 1.3-30.6 mg/m3 air.
  Investigation as to the frequency of silicosis
among the Pb miners revealed that almost all cases
(involving from 9.2% of the workers in 1954 down
to 0 in 1962)  had occurred at the mine Ak-Tyuz,
operating since 1932.  At the other mines that
started operation since 1950, only occasional
cases were encountered.   It was obvious  to the
author that the general tendency toward  a decline
had begun before the survey was started.  He con-
cludes that improved working conditions had re-
duced average dust concentrations to levels below
the maximum permissible,  so that no more new cases
of pneumoconiosis were observed.
  In order to investigate the biologic reactivity
of the dusts,  white rats  were injected intratrache-
ally (without anesthesia) with ore dust  containing
4.5-50% quartz and from traces to 5% Pb  sulfide.
The results confirmed the reactivity of  the dusts
on lung tissue in proportion to the free silica
contained in them.  At the concentrations present,
Pb sulfide had no effect  on the development of
pneumoconiosis.   (A footnote by the editor of the
 journal  states  that  the  data reported  do  not  per-
 mit  the  assumption that  concentrations of Pb  sul-
 fide of  this magnitude are  innocuous to the organ-
 ism.)

In  the first years of operation, a high incidence
of  Pb poisoning occurred in the  agglomeration,
smelting and refining of Pb , which are among the
operations at the Ust-Kamenogorsk mines, indi-
cating ineffective controls.  The greatest number
of  cases occurred in the first 2 processes men-
tioned above in 1953 (from ^50-71% of the workers
showing some occupational illness) .  With system-
atic improvements in control measures, there was
marked and continuing decrease in illness.  Taking
1953 figures as 100%, by 1960 incidence fell to
2.3% and by 1961, to 0.5%; however,  in 1962 there
was some increase, to 1.2%.  In  1953 a permanent
commission was organized to institute an engineer-
ing and hygienic prograa which included education
of  workers, removal from work of those showing
illness.  For personnel protection,  a special res-
pirator was introduced which retains 93.4-97.6% of
the Pb aerosols.

"'We have to  announce the death of Mr.  Robert  Ba-
ker, C.B. ,  formerly one of the chief inspectors
of factories,  in his 77th year.   Mr.  Baker began
life as a member of the medical profession,  and
devoted great attention to the condition of fac-
tory operatives.   In 1834 he was appointed sub-
inspector of  factories under the Factory Act and
in 1858 was made one of the chief inspectors.   On
his retirement he was created C.B.  of the Civil

workplaces receive attention.  From the successes
and failures of a doctor, well placed to view
these ever-present problems, we may be guided in
our current attempts to deal with them."
  In Part II, the events leading to the Factories
Act of 1878, which was the first to appear in the
form recognized currently, are reviewed.  In that
year, Baker reached the age of 75 and resigned
from his position as 1 of the 2 Factory Inspec-
tors (held from 1858;, after he had earlier com-
pleted 25 yr of service in the Factory Department.
His area covered the N-W of England, the midlands,
and the W country together with the whole of Wales
and Northern Ireland and at the time of his re-
tirement contained 23,346 factories and workshops.
In this position he supervised the enforcement of
factory legislation and recommended changes in
legislation.  During this time he had worked in
bringing various trades under regulations in re-
gard to disease and hygiene (cotton mills, silk
mills, pottery manufacture, and percussion cap
making).  He tried to effect measures to prevent
harmful effects of dusts (proper ventilation,
respirators), but had a defeatist air about this.
  Pb poisoning was also a big industrial hazard of
the period and Baker criticized the Factory Acts
Extension Act of 1864 from the standpoint of
housekeeping, cleanliness, and proper work
clothes.  He suggested that workers should wash
properly before meals and before going home, that
meal-time regulations in the factories should be
applied to all workers (men, women, and children),
and that disciplinary regulations for work-cloth-
ing should be instituted.  Although Baker had at
first seen the problems clearly, as the years went
by he became confused and seemed to put hygienic
preventive measures second to dietary treatment of
the worker.
  Among his other contributions were: advice that
certifying surgeons visit factories regularly once
a month; rigid medical supervision of all facto-
ries where children and young people were em-
ployed; changing type of employment temporarily
when injurious effects were noted.
  Many of Baker's ideas in industrial medicine
were well in advance of his time but, probably be-
cause he was too preoccupied with the problems of
the past, the control of infectious disease, and
the protection of children, he failed to get his
ideas implemented.  However, Baker's work was
recognized and appreciated by those he sought to
help.  (166 references)

The composition of dust deposited on the mine
walls showed that during the drilling and blasting
of ore and rocks all products of decomposition are
deposited as dust containing large amounts of the
fraction <10 u, the most dangerous fraction of
the source of pneumoconiosis.  By a study of the
type of dust present in surrounding rock, it is
therefore possible to evaluate the degree of the
dust toxicity even before mining.  In ore and rock
dust of the Temir-Tausk deposit Zn, Pb, As, and
                other elements are present.   They can aggravate
                the toxic effect of quartz.   The strict suppres-
                sion of dust formation in all mine works is neces-
                sary to prevent pneumoconiosis.  (From Chemical

                Complaints by  personnel of the spectrographic lab-
                oratory of the Scientific Institute of Non-Ferrous
                Metals led in  1959 to an investigation of the hy-
                gienic conditions.  The atmospheric survey of the
                premises included analyses of samples for Pb, As,
                Zn, Hg, and Se by chemical methods as well as
                spectrographic, and for other metallic components
                only by spectrography.  In spite of certain pro-
                visions for ventilation,  high contamination was
                found in the breathing zone  of the workers par-
                ticularly during the grinding of the metals.  The
                men did not use respirators  or other means of per-
                sonal protection.  The principal offenders were
                Pb, As and Hg.  The concentrations encountered in
                the air samples collected at the spectrographic
                apparatus while no analyses  were being done ranged
                as follows: Pb, 0.02-0.15 mg/m3; As, 0.03-0.13;
                Hg was not determined.  The values for the respec-
                tive metals at the same site while analyses were
                run ranged from 0.18 and higher; 0.10-0.33; Hg,
                0.05-0.10.  At tables while samples were being
                ground, 0.11 and higher; 0.62-1.09; 0.04-0.08.   In
                the laboratory rooms while analyses were run,
                0.09-0.17; 0.04-0.28; and 0.04-0.06 mg/m3, respec-
                tively.
                  All personnel,  32 men, of whom 20 complained of
                headaches, were subjected to medical examination.
                A number of them  exhibited tremors, several had
                dermatitis.   In 75% somewhat lower red  cell counts
                were observed, and in 50% the Hb levels were 70-
                79% of normal and less.  Other abnormalities in
                the blood picture included decreases in the number
                of leukocytes, neutrophils, monocytes,  eosinophils,
                and thrombocytes.  The following safety measures
                were instituted:  increased ventilation, tight
                hoods over the  spectrographs and sites where sam-
                ples were prepared for analysis, enforced wearing
                of respirators and rubber gloves.  Two  shifts were
                established so  that the  number of spectrographs
                used was reduced  and  personnel were instructed as
                to hazards.   These measures  effected considerable
                improvement in working conditions.

         1964.
 A wide range of anticorrosive primers has been  de-
 veloped  to  prevent the deterioration  of  ferrous
 metal surfaces during  fabrication processes.  The
 welding  of  primed prefabricated parts into their
 proper position, such  as is done in shipbuilding
 and other structural work, gives rise to toxic
 hazards  due  to the thermal decomposition of the
 paint film.  The oxidation products of the metals
 or metallic  salts that form the primer pigment  may
 vary in  toxicity ranging from the relatively non-
 toxic Fe and Ti oxides to the highly  dangerous
 oxides of Cd, C'r and Pb.  Aside from  these haz-
 ards, the hydrocarbons and resins give rise to
 other toxic  decomposition products among which  are
 Co, N oxides, phosgene, cyanides and  diisocya-
 nates.
  The occupational hygiene services at Newcastle-
 upon-Tyne,  Slough, and Manchester have recently
 developed standard toxicity tests for primers,
 i/ith laboratory cutting and welding processes ar-
 ranged to simulate those found in the field.  When
 the results  indicate that the toxic decomposition
 products do  not exceed their maximum  permissible
 levels,  the  primer is  stated to be suitable for
 flame cutting or welding under "open  shop" condi-
 tions and for welding under enclosed  conditions
 provided ventilation complies with the standards
 for good welding practice.  The method used for
 these tests  and the results obtained, using a Zn
 oxide primer, are described.
scratches of various sorts after use of these
means.  The Pb content in the wash water (102-116
samples) of workers engaged in various jobs was
analyzed before work, before meal break, and after
work.  The respective average concentrations found
after use of hot water and soap, or soap with soda
were, inmg: typesetters, 0.35 (0.01-2.10), 0.9
(0.01-6.4), 0.6 (0.20-1.33); printers, 0.40 (0.01-

(0.10-0.50);  stereotypists,  0.50 (0.40-0.94),
0.6 (0.30-0.90), 0.6 (0.27-1.40).  As these
values showed insufficient cleansing, a paste
to be applied to the skin before washing with
cold water was formulated by the authors.   It
consists of "OP-7" 1000 g, paraffin 160 g,  3%
solution Na hydroxide 800 g,  glycerin 240 ml.
Analysis of 122 samples of wash water after its
use before work and after work gave the follow-
ing average Pb content in mg:   typesetters,
0.010 (0.007-0.070), 0.02 (0.001-0.08); printers,
0.007 (0.004-0.014), 0.01 (0.005-0.02); lino-

stereotypists, 0.020 (0.010-0.040), 0.001
(0.009-0.06).  This paste is stated to promote
softness of skin,  maintain its elasticity,  and
to have slight bacteriostatic  property.

At  a  symposium the technical factors of internal
combustion were briefly described and the state-
ment  made that the present engines can be generat-
ed  virtually only with relatively high antiknock
leaded  gasoline.   It was calculated on the basis
of  an annual gasoline consumption of 220,000 tons
 (1948)  in Switzerland that a mixture of 76 tons of
pure  Pb  or 135 tons of Pb bromide is used.  A
brief description of the determination of Pb in
gasoline and the chemical composition of the ex-
haust gases is presented.  In conclusion it was
stated  that the TEL gasoline problem can be solved
in  Switzerland, by addition of 15-20 vol % ethyl
alcohol.  All that is needed is cooperation of the
gasoline industry.

Daily, diurnal, and seasonal variation in the at-
mospheric dust of a number of stations were
studied from samples collected in Cincinnati with
a small portable electrostatic precipitator.  Nine
constituents were determined; for Pb results in
yg/m  air, averaged over a 3-yr period, were:
control areas, 0.001;  residential and semi-resi-
dential areas, 0.002;  business and industrial
areas, 0.0037.  For the different seasons, Pb val-
ues were:  cold months, 0.0038; cool months,
0.0043; warm months, 0.0027; over-all average,
0.0037.

The author reviews the history of the introduction
of TEL antiknock and its attendant health hazards
to the personnel manufacturing and handling the
fluid in the early 20's in the US, followed by
experiences in Britain when this antiknock agent
was introduced there in 1944.  The decision in
1947 of the Swiss Government to use the TEL anti-
knock agent in gasoline has led to the creation of
a Commission to study the effects of Pb-containing
gasoline on the population, garage mechanics, and
others exposed to auto exhausts containing Pb.
The conclusions of the author are that there is no
need for excessive apprehension; however, the pub-
lic and the auto industry personnel should be
alerted as to any precautions that need to be tak-
en.

Pb poisoning occurs in animals  in the neighbor-
hood of Pb foundries and other industries which
emit Pb fumes or dust.  The most contaminated
places are located in the Harz,  Westphalia, the
Rhineland and WUrttemberg.  Contamination of air
and of water by Pb dust or Pb wastes as well as
flooding of fields by such contaminated water can
also produce poisoning; finally also Pb water
pipes.  The physiologic and toxicologic question,
the symptomatology, diagnosis and therapy of Pb
poisoning in animals are discussed and measures
for the control of these hazards are recommended.
They consist primarily in the removal and decon-
tamination of Pb-containing industrial dusts, in
the avoidance of feeding Pb-contaminated plants,
thorough cleansing of contaminated feeds, in the
shielding of chicken houses against fly ash and
in the education of the farmers in the affected
areas.  Many questions are still not clarified
and need further study by means of animal experi-
mentation.  (From Zentralblatt  fur Arbeitsmedizin

A troublesome problem in atmospheric pollution was
presented by the operation of a small Pb smelter.
Discarded storage battery plates were being re-
duced to metallic Pb with a .small content of Sb •
The dense fumes given off in the process created
a serious nuisance in a nearby housing develop-
ment, as shown by the fact that the Pb concentra-
tion in the smoke at a distance of 1,000 ft down-
wind was in excess of the MAC permitted in indus-
trial operations.   Executives of the company made
some changes in the process when the hazard was

drawn to their attention, but the nuisance per-
sisted.  The residents of the community obtained
an injunction, halting the operation of the
smelter until the nuisance could be corrected.

In making an X-ray diffraction study of the inor-
ganic Pb compounds occurring in engine deposits,
the importance of their formation by solid-state
reactions was  recognized.  In a study of numerous
solid-state addition and replacement reactions be-
tween inorganic Pb salts, it was learned that all
the compounds  commonly found may be produced as
a result of addition reactions which take place
in the solid state between various Pb salts and
Pb monoxide when mixtures of these are heated at
temperatures well below their melting points.  The
resulting or surviving products of the solid-
state reactions are determined only by the temper-
ature and by the mole ratio of the Pb monoxide
to the normal  Pb salts.  Examples are given of in-
creased reactivity due to the ability of metasta-
ble yellow Pb  monoxide to form a reactive red Pb
monoxide when  heated in the presence of a 2nd com-
pound with which Pb monoxide will readily form an
addition product.  This property is believed to
be important in the mechanism of ttie solid-state
reactions studied, and its possible relation to
engine combustion phenomena is suggested.  Inter-
planar spacing values are given for the major re-
flections of inorganic Pb compounds commonly oc-
curring in engine deposits:  PbO.PbBr2 (2 forms),
PbO.PbCl2, PbO.-PbCl.Br (2 forms), 2PbO.PbBr2,
2PbO.PbCl2, 2PbO.PbCl.Br, PbO.PbSO^ and 4PbO.

Consolidated Mining and Smelting Co. of Canada has
operated a Pb  smelter at Trail, B.C.   This company
commenced planning a program of smelter revision
and modernization some years ago.  The 1st stage
of this program involved design and construction
of a new blast-furnace gas-cleaning system.  The
essential problem was to clean and collect 100
tons of dust/day from 153,000 cfm  (12,225 Ib/min)
of Pb blast furnace gas varying in temperature
from 350-1100°F.  It was desired to collect the
dust dry; therefore either a baghouse  or a Cottrell
cleaning plant was to be selected.  The equipment,
design of facilities, and preliminary  operating
                details of the baghouse system (chosen because of
                limitation of space) are described.

                        Symposium, 1952, pp. 6-15.
                The purpose of the report was to describe the
                nature of air pollution in Cincinnati, and to
                compare Cincinnati data with findings obtained
                during the course of shorter studies in other com-
                munities, as well as with observations reported in
                the literature.  Pollutants discussed were:  CO,
                C02, N oxides, aldehydes, S02, chlorides, ammonia
                and its salts, F, and particulate matter.
                  The average composition of suspended matter in
                the Cincinnati atmosphere showed Pb ranging from
                <0.1-11.5 Mg/m  air in 724 samples, mean for all
                areas sampled being 2.7 and the rural area mean,
                1.2.  Quantities of the 22 individual components
                tended to vary with the increasing activity of an
                area.  For Pb, increase in quantities occurred
                proceeding from rural through industrial areas,
                with density of traffic also affecting quantities.
                Yearly Pb variations for various sections in Cin-
                cinnati  (rural, residential, industrial and com-
                mercial, all areas, respectively) in pg/m  air
                were:  1946-47: 0.8, 2.3, 4.1, 3.0; 1947-48: 0.95,
                1.6, 3.4, 2.7; 1948-49: 1.3, 1.7, 3.6, 2.7; 1949-
                50: 1.3, 1.7, 3.5,  2.5; 1950-51: 1.2, 2.5, 3.0,
                2.6; 5-yr av: 1.1,  1.94, 3.5, 2.7.  The drop in
                average Pb concentration in the atmosphere in
                1947-48 was due to  a city code requiring  the use
                of low volatile coal in hand-fired units, in-
                creased use of gas  and oil for industrial pur-
                poses, and installations controlling fly-ash emis-
                sions.  From then on the average remained station-
                ary.  In comparing  communities the following fig-
                ures for atmospheric Pb in  Mg/m  air were given:
                Cincinnati, 2.7; Baltimore, 1.0; Charleston, 0.6;
                Donora,  4.5; Los Angeles, 0.8-6.0.   (16 refer-

                This report concerns the nature and quantities of
                some of  the commoner materials which were found
                in  the atmosphere in Cincinnati from Nov  1946-
                Nov 1951 covering 12-18 fixed stations.   Deter-
                mined were:  settled dust,  suspended matter,  S
                compounds, halides, CO, C02, aldehydes, nitrates,
                and odors.  Twelve  pollutants,  including  Pb
                (<0.01-1.7%, av 0.122%), were analyzed quantita-
                tively in ^300 samples of settled dust.   (See also

                trial sources this  probably occurs as Pb  oxide and

from automotive exhausts as Pb chloride or bro-
mide.  The role of Pb fumes as possible smog-
forming contaminants in Los Angeles air is still
a matter of conjecture.  Nevertheless, a  concen-
trated effort is being made by nonferrous indus-
trial concerns to reduce Pb emissions in  order to
protect employees and improve air hygiene.  These
reductions are aimed at Pb reclaiming operations,
Pb alloys, and Pb in furnace fumes  (ie, stack
effluents, recovery equipment).

The principles of the Committee for the Determina-
tion of Allowable Concentrations are discussed.
The headquarters of this Committee  are at the
F.F. Erisman State Sanitary Institute.  In this
report, norms for 10 pollutants and their substan-
tiation are given.  Additional material will be
published by the Committee as results of  further
investigations accumulate.  The author admits
that the limits are not based on irrefutable evi-
dence; indeed, they are also based  on some arbi-
trary assumptions and values.  The  norms  present-
ed here should be evaluated as collective opinions
of groups of specialists who, in the light of
existing knowledge, agreed that certain concen-
trations could be adopted as limits of allowable
concentrations; they will be subjected to reexam-
ination, refinement, correction and revision as
more scientific and basic evidence  accumulates.
Emphasis is laid on the study of the higher ner-
vous activity, on which practically no data were
available at the time of preparation of the re-
port.  The 10 substances for which MAC's were
proposed include Pb:  for single exposure, not
determined; daily average, 0.0007 rag/ia3.  A note
specifies that the norm for Pb does not apply to
TEL; this will be specified later.  Requirements
for the calculation of levels of exposure, dis-
charges from source, collection and determination
procedures are outlined.

based on a reaction with K chromate, has a sensi-
tivity of 0.001 mg/ml.  The limit of allowable con-
centration of Pb in atmospheric air is given as

The occurrence of Pb in nature, including the ani-
mal organism is briefly reviewed on the basis of
the Russian literature.  Pollution of air by vari-
ous processes is discussed.  Examples:  in the
smelting of silver, the air becomes polluted with
dust which may contain 25-45% Pb.  In the Dwight-
Lloyd process of calcining Pb ore, the air in
close proximity may contain 273-1799 mg/nr' dust
with 109-245 mg/m3 Pb.  It was estimated that 25
tons of Pb are discharged annually by 1 calcining
oven.  The slag contains 0.8-1% Pb; it should not
be used in street and road improvement.  The effi-
ciency of S-filters for the control of Pb-contain-
ing dust was found to be 94-96%.  The quantity of
dust falling out of the air near a nonferrous
metallurgical plant was found to be  (in mg/m-Vday):
at 100 m,  2602; at 300 m,  2141;  at 500 m,  1355;
Pb content, in %:  6.7, 0.4, 1.4, respectively.
Dust washed off window panes contained Pb in mg/m3
on the outside of the building:   at 300 m, 8.0;
at 800 m,  2.3; at 1,000 m, 0.3;  on the inside:
0.5, 0.5 and 1.5 mg/m3, respectively.  By the
aspiration method, the air over the factory grounds
contained_0.05 mg/m3 Pb; at 300 m from factory,
0.02 mg/m3.  Fly ash from coal combustion contains
0.015-0.01% Pb and is a constant source of pollu-
tion.  A distinction is made of the hazards of Pb
exposure as to ingestion vs inhalation.  The lat-
ter is more harmful since Pb bypasses the liver
and enters the blood stream in a more direct man-
ner.  Kantaron found Pb by inhalation to be 10 to
100 times as toxic as Pb is by ingestion.  The
significance of the physico-chemical state of Pb
and particle size and health hazard are discussed.
Experiments with rats kept for 5 mo at 300 m dis-
tance from the point of discharge of a nonferrous
metallurgical plant, atmospheric Pb 0.02 mg/m3,
proved that the continued inhalation of this con-
centration led to an accumulation of Pb in the
organs, which can produce chronic poisoning.  Ac-
cumulation of Pb in leaves and soil near the fac-
tory was also demonstrated.  On the basis of
Kehoe's observations the daily ingestion of 0.15-
0.20 mg Pb causes no harm; since, however, inhaled
Pb is 10-100 times as toxic, the safe daily intake
via respiration should be 0.0015-0.0020 mg.  On
the basis of a daily air ventilation of 15 m3, the
air breathed in should not contain more than
0.00010-0.0013 mg/m3.  The author proposes the
average of the 2 values, 0.7  yg/m  as the maximum
allowable concentration in air in residential re-
gions.  This is ^14 times lower then that for work-
rooms, which is 10 yg/m3.   The low MAC of 0.7 yg/m3
is justified on the basis that if 1.23 mg% is taken
as the average Pb content of clean soil, an atmos-
spheric dust concentration of 0.2 mg/m  will con-
tain 0.0025 yg/m3 Pb, and one of 2 mg/m3, 0.025
yg/m3; thus, the proposed MAC exceeds the Pb con-
centration of clean air at least 28 times.

        Laboratory, College of Medicine, Univer-
        sity of Cincinnati:  ATMOSPHERIC POLLUTION
        IN THE GREAT KANAWHA RIVER VALLEY INDUS-
        TRIAL AREA.  FEBRUARY 1950-AUGUST 1951.
        Report prepared with consultation and as-
        sistance by the U.S.  Fublic  Health Ser-
        vice, Division of Occupational Health,
        1952, 168 pp.
The purpose of this study was to (1) establish
factual information as to the air pollution prob-
lem of the Valley, (2) compare the present parti-
cle-fall load to that of a previous  survey made  by
the Bureau of Industrial Hygiene from June 1945-
December 1947, and (3) determine the present or
future needs of establishing an aggressive air
pollution control program for the area.  It was
not the intent to study the effect on health of
the air pollutants in the Valley nor to determine
the specific control measures that might be needed.
The work is divided into 5 chapters:  (1) General
information, scope of survey, methods of survey,
and factors limiting survey;  (2) presentation and
interpretation of pollution data collected by the
Bureau of Industrial Hygiene of airborne contami-
aants other than that measured by particle-fall
methods, also an account of some noticeable ad-
verse effects due to air pollution in 1950-51;
(3) particle-fall study by the Bureau of Indus-
trial Hygiene including comparison of data ob-
tained with previous soot-fall study by the Bu-
reau; (4) presentation and interpretation of at-
mospheric pollution data of studies by the Ketter-
ing Laboratory using mobile sampling unit with a
summary of results obtained (report prepared by
J. oholak and L.B. Roberts);  (5) emissions to the
atmosphere (exclusive of the area from Cabin Creek
to Glen Ferris).
  A table giving concentrations of 18 elements
(collected with high volume filter samplers) in
the atmosphere as found in particulate matter at
9 locations in the Great Kanawha River Valley in-
dustrial area listed Pb as ranging from 0.01-0.65
yg/rn^ air.  The 8 stations and their results were:
Chelyan, 0.18; Station Belle, 0.01;  Kanawha City,
0.12; Charleston, 0.65; North Charleston, 0.12;
South Charleston, 0.02; South Charleston station,
0.02; Saint Albans, U.16; Nitro, 0.18.  Another
table showing results of spectrographic analysis
of particle fall collected at 17 stations for the
month of July 1951 showed Pb ranging from 0.015-
>0.2 mg/10 mg of particle fall.  All stations reg-
istered >0.2 except 2 (Belle, 0.015 and South Mai-
den, U.o8).  In response to questionnaires to
various plants, railroads, steamboats, municipal
operations, laundries, lumber mills, and hospi-
tals, Pb fume was emitted to the atmosphere from
industrial processes at a rate of 0.4 tons/day.
Total particulate matter emitted was 505 and total
gases and vapors, 369 tons/day.
  The results of the study showed that a major air
pollution problem does exist in the Great Kanawha
River Valley industrial area, particulate matter,
gases, and vapors constituting a major portion of
the problem.  While some of these latter are
known to be extremely toxic in sufficient concen-
tration, their toxic effects in the lower concen-
trations found in this survey are unknown.  It was
further concluded that the major air pollution

                the planning of new, or improving and rebuilding
                of existing industrial establishments.  The basic
                requirements for general planning are defined,
                such as site of enterprise, conditions,  classifi-
                cation of industries according to volume of dis-
                charges with magnitude of required clearance zone.
                In Supplement 1, the types of industries are list-
                ed under the Sanitary Classifications of Produc-
                tion and Processing Plants in Relation to Sanitary
                Clearance Zones: A clearance zone 1000 m wide is
                required for smelting of non-ferrous metals direct-
                ly from ores or concentrates, including Zn, Pb, Sn,
                Ni; a 500-m-wide zone, secondary processing of non-
                ferrous metals in quantities up to 3000 tons/yr;
                a 300-m-wide zone, production of storage batteries
                on a large scale, of non-ferrous metals up to 1000
                ton/yr, of Pb-coated or rubber-insulated cables;
                a 50-m-wide zone, thermal working up of metals
                (except foundries), production of batteries on
                small scale; a 500-m-wide zone for production of
                Pb, As, and Mn ores.
                  Supplement 2 lists contraindications for employ-
                ment of workers in industries:  specific contrain-
                dications apply to workers undergoing periodic med-
                ical examinations; in addition, there are general
                contraindications for employment of workers.  These
                are presented in 3 lists for Pb and its  organic
                compounds, Pb containing gasoline, and TEL and
                ethyl fluid.  The contraindications are certain
                disorders of the central and peripheral nervous
                system, the endocrine system, visual and auditory
                apparatus, cardiovascular, liver, kidney, alcohol-
                ism and all diseases of the respiratory system
                contraindicating use of gas masks.
                  Supplement 3 gives the Limits of Allowable Con-

         2:62-5,  1953.
 Five  children and 5 adults  in 3 families  were  found
 to have  absorbed Pb from  a  common  source.   Three  of
 them  had clinical symptoms.  One child of 18 mo had
 Pb encephalopathy; one, age  2 yr,  9 mo, had gastro-
 intestinal symptoms;  and  1  adult had malaise and
 pains in the limbs.  The  remainder all had  definite
 evidence of Pb absorption, but no  symptoms.  Inves-
 tigation of the  source revealed that the  houses in
 which these families  lived were in a narrow lane
 with  a coffin factory opposite. Pb used in  fittings
 was moulded and  polished  in  the back of the factory,
 and 2 extractor  fans blew dust from the factory into
 the lane.  There were also many small  waste pieces
 in the gutters that were  being collected  by the
 children to play with.  The  urinary Pb concentra-
 tions ranged from 0.03-0.55  mg/1.  Findings in  all
 10 cases are briefly described.

 Air pollution and hazards  to health arising from
 the use of leaded gasoline are discussed  and il-
 lustrated with the author's  observations  acquired
 in his dental practice from  patients regarded by
 their physicians, in many  cases, as hysteriacs  or
 malingerers because of their various unexplainable
 ailments ranging from headache, dry nose,  colitis,
 kidney disturbances, rheumatic signs,  tremor, etc
 to itching of the skin, eczema,  temporary visual
 impairments, and others.   He describes his  own
 case when he and his wife got sick after  a  car
 trip during which they had been exposed to  gaso-
line odor coming from a faulty carburetor.  For
several days he had suffered from backache  accom-
panied by vegetative dystonia and inflammation  of
the nose with abscess formation while his wife had
impetigo-like skin lesions of the nose.  Personal
communications with garage workers, families liv-
ing in apartments located above garages,  and
others, as well as his own experiences are  quoted
as evidence against the use  of leaded  gasoline.

While the review concerns the evaluation of dust
collectors to improve working and operating condi-
tions, the authors point out that when there are
possibilities of air pollution or public nuisance,
and/or when there is a valuable product to be col-
lected, selection is often guided by the maxim of
"highest available collection efficiency at reason-
able cost and reasonable maintenance."  The princi-
ples of dry centrifugal collectors, fabric arrest-
ers, wet-type collectors, the high-voltage Electro-
Static precipitator, and high-temperature gas
cleaning are discussed.  In connection with the
latter, the Pb sintering process is discussed;
there, the loss of salvageable material and atmos-
spheric contamination require maximum dust control
measures.  High dust loads occur, varying from 3-
10 grains because of the release of hot gases, as
do duct accumulations since gases in the exhaust
system are frequently below the dew point.  Test
analyses, using good wet collectors gave collection
efficiency >99% Pb.

Autoclave experiments with a 10% ethyl-fluid-con-
taining gasoline solution showed that with the
use of S-free gasoline, Pb bromide, oxide, trieth-
yl Pb bromide and oxidized hydrocarbons occur as
decomposition products.  The decomposition of the
ethyl fluid is principally temperature dependent.
At temperatures up to 100°C and pressures of 20-
60 kg/cm2 mainly Pb oxide is formed; at higher
temperatures and various pressures, the formation
of Pb bromide is favored.  The Pb triethyl bromide
forming at lower temperatures (up to 100°C) and
high pressures (60 kg/cm2) has good antiknock
properties.  (From author's summary)

        tional Medicine 10:203-9 (Sept.),  1954.
In discussing the title subject, the author points
out that the determination and measurement of the
constituents of  the atmosphere on a comprehensive
scale are of rather recent origin.   Interest has
been stimulated by dramatic incidents such as the
Meuse Valley (1930),  Donora (1948),  Poza Rica
(1950)  and London (1952)  disasters.   While inves-
tigating air pollution around well-defined indus-
trial processes is often a simple matter,  the mea-
surement of air pollution in relation to community
health offers many difficulties, not the least of
which is the fact that single pollutants can rare-
ly be incriminated.  In only 1 of the above dis-
asters (Poza Rica)  could a single pollutant be
held responsible (l^S) .  The exact composition of
the atmosphere will always remain somewhat inde-
terminate because it contains a great variety of

materials, not all of which are man-made.   From
time to time numerous materials of known toxicity
will be reported as having been found.  While very
sensitive analytical methods are available for the
determination of many of the pollutants, there are
a number of common pollutants for which no specif-
ic methods are available.  For this reason, even
so-called comprehensive investigations are con-
cerned with the determination of relatively few
pollutants.  Examples of this situation are given
in respect to several investigations in the US and
England.  Among them, recent data from a coopera-
tive country-wide investigation of the USPHS and
the Kettering Laboratory are shown in a table,
giving averages and ranges, and, for comparison,
threshold concentrations for Pb, Hg, Cd, As, Be,
S compounds, nitrates and benzpyrene, in which Pb
values are 2.0, 0.1, and 150 yg/m , respectively.
  In closing, the author states that although data
are available on certain air pollutants, proce-
dures and equipment are lacking for collecting and
analyzing these and many other pollutants during
adverse weather conditions, and that no satisfac-
tory understanding of the impact on community
health can be achieved without fairly comprehen-
sive information of this type.  (18 references)

        HORSES AND A SHEEP WITH FLUE DUST FROM A
        METAL FOUNDRY.)   Dissertation, Veterinary
        College, Hanover, 1954, 47 pp.
Signs of poisoning were observed in animals graz-
ing within a 5—km radius around a Zn and a Pb
foundry.  Analysis of the flue dust in 1951-52 in
these areas and around 2 Dwight furnaces showed
it to contain 5.21-53.5% Zn, 5.2-44.8% Pb, and
smaller amounts or traces of S, Cl, Cd, As, Fe,
and F.  Cattle, and particularly young horses,show-
ed signs thought to be characteristic of chronic
and/or acute Pb poisoning.  There was rapid emaci-
ation, cachexia, swelling and stiffness of joints;
milk production decreased.  The foundries granted
compensation for dead animals with livers showing
iO.2 mg Pb/100 g.   Findings on 3 affected colts
are reported in detail.   Two showed leukocytosis;
otherwise the  blood findings were not remarkable.
Rickets could be excluded.  Of interest was the
finding at necropsy of an increased volume of syn-
ovial fluid in affected joints and detachment of
the articular cartilage from the bone.  Analysis
of the livers for Pb and Cu gave 0.23-0.39 and
1.0-3.4 mg/100 g, respectively.  A colt and a
sheep were fed hay grown around the Pb foundry
(60-65 mg Pb/kg content) and flue dust collected
from the Pb foundry (44.8% Pb) with their ration.
The colt received 5 g of the dust 3 times/day for
22 days and 20 g/day for another 7 days.  It be-
came unable to swallow, the mucosa appeared icter-
ic, leukocytes increased greatly.  Toward the end
of the feeding period, severe paralysis of the re-
current nerve caused swallowing difficulties and
led to pneumonia.   This, and the "roaring" found
in the affected areas were attributed to Pb poi-
soning.  The liver contained 1.52 mg Pb/100 g.
The sheep was given flue dust in doses increasing
from 2-24 g/day.  When the appetite decreased
sharply, the dose was reduced to 4 and 2 g.  The
                 liver was  found  to  contain  0.14 mg  Pb/100  g  at
                 the end of  the experiment.   This  relatively  low
                 content is  thought  to  be  attributable  to differ-
                 ences in the metabolism of  Pb  in  the 2  species.
                  The author carried out  an experiment  on  a  6-mo-
                 old colt, not previously  exposed, by feeding it
                 flue dust  from 1 of the plants  (23.41%  Zn, 16.87%
                 Pb, 5.8% Fe, 12.53% S, 2.22% Fe,  0.05%  F,  0.52%
                 As).  The  daily  dose in the ration  (in  the later
                 stages the  dust  was administered  through the nose)
                 was variable (in g with number of days  in  paren-
                 theses) :   3 (8), 5  (13),  8  (26), 10  (12), 15 (6), 20
                 (9), 30 (48); after 15-day  interruption, 10  (31),
                 30  (29) followed by sacrifice.  A total of 3270
                 g flue dust was  thus ingested.  The appetite began
                 to  decrease at the 10-g dose;  the gait  became
                 stiff, the  animal appeared  very sick.   The leuko-
                 cyte count  increased and  fluctuated, the Pb  con-
                 tent in the blood was  0.466 mg/100  ml  in the high-
                 ly  acute stage and 0.200  mg/100 ml  shortly before
                 death.  Necropsy revealed no macroscopic changes.
                 Microscopically, the liver  contained some  fine
                 intracellular yellow-brown  pigment  and  the kidneys
                 were slightly necrosed.   Analysis of tissues and
                 fluids yielded,  in mg Pb/100 ml,  0.200  in  the blood,
                 0.055 in the spinal fluid;  in  mg  Pb/100 g, 2.770
                 in  the liver, 0.670 in the  kidneys; 0.06%  F  in  the
                 rib bones  (ash).  Although  the F  content of  the
                 flue dust was low, special  attention was paid to
                 it because  of the bone changes observed.   The au-
                 thor's opinion is that this was not purely a Pb
                 or  F injury but  one attributable  to the combined
                 action of  several constituents of the  flue dust.
                 Thus, in this instance the  syndrome should be con-
                 sidered as  an injury typical of flue dust.

  Five cities with populations >2,000,000 sampled
for at least 1 full yr exhibit a high organic-
fractional average and a high totc-1 particulate
loading  (av 264 yg/m3, almost the same as Los An-
geles, av 265 yg/m3).  Pb, the occurrence of which
may be related to the production and combustion of
Pb automotive fuels, amounted to an average of 9.5
yg in Philadelphia, 5.2 in Los Angeles,  2.8 in Chi-
cago and New York, and 2.9 in Detroit.  Values for
the' same kinds of averages for cities of intermed-

av of 137 yg/m3 (7 cities) with averages of Pb
ranging  from 0.5 yg/m3 in Minneapolis to 2.4 yg/m3
in San Francisco.  The other cities were: Cincin-
nati, Kansas City, Portland, Atlanta, Houston.
Five small cities with atypical (high) loadings due
to volcanic dusts or ashes (Anchorage), heavy indus-
try (Charleston, W.Va.), dust storms (Ft. Worth),
or other unknown causes (Louisville) showed a total
particulate load ranging from 308 yg/m3  (Anchorage)
to 110 (Ft. Worth).  Pb concentrations ranged from
0.6 yg/m3 (Louisville) to 1.2 (Anchorage).  Five
rural sites gave a total average load of ^65 yg/m3,
the composition seeming to relate best to the com-
position of the local topsoil.  Pb values ranged
from 0.1-0.9 yg/m3.

as well as atypical areas mentioned above, are in-
cluded and illustrated by several figures and
graphs.  Studies which demonstrated no obvious sea-
sonal trend for particulate loadings in the 5 rur-
al areas indicated that the causes  of the central
city autumnal rise must be sought within the city
itself and not in terms of regional climatology.
However, the authors point out that evaluation of
the data may not meet the demands for perfection,
as they do not, for instance, include analysis of
vapors and gases, and that many choices have had
to be made on the basis of practical expedience
rather than scientific merit, thus leaving room
for possible criticism of  data presented.

        THE NATURE OF THE SUSPENDED MATTER.  In

The particulate matter in the atmosphere of the
Los Angeles area, collected daily at 2 stations
for 4 mo (Aug-Nov 1954) was analyzed to determine
its composition and the fluctuations in the con-
centration of certain components,  and compared
with that found in other metropolitan areas for
the same period of time.  The amounts of Pb pres-
ent in ^2400 spot samples of dust collected on
paper tapes with AISI smoke samplers were deter-
mined by a chemical method.
  Mean Pb results (ranges in parentheses) for the
2 stations (Los Angeles station 3 and Pasadena
station 4) for Aug, Sept,  Oct, and Nov, respec-
tively, in yg/m  air, uere:   Station 3:  0.13
(1.7-7.6);  6.2 (1.4-14.7);  7.5 (3.1-13.8);  8.3
(3.2-16.4).   Station 4:  2.2  (1.1-4.1);  4.4 (0.8-
12.8); 5.0 (1.9-10.4); 4.65 (1.2-11.4).  The same
Pb information for 30 metropolitan areas in the US
and Alaska during 1954 was 2.15 yg/m  air (0.1-
26.6).  Thus the average concentration  of Pb  in
the atmosphere of the Los Angeles area  was 2-3
times greater than that for the  30 metropolitan
areas.  However, the maximum concentration found
was lower than the maximum which occurred from
time to time in the atmosphere of certain other
American communities.  The higher concentrations
of Pb in the Los Angeles area occurred  usually
during periods of low-lying haze.  The  highest
single concentration during the  investigation
(16.4 yg/m3 air) occurred during the 24-hr period
which began at noon on Nov 24.  Figures are also
given which illustrate that the Pb concentrations
at both Los Angeles stations increased  during the
early hours of the evening.  In addition daily
averages, in yg/m , of particulate Pb compounds
analyzed in the atmosphere of certain cities were
tabulated:  Los Angeles, 6.75; Pasadena, 4.2; New
York and Chicago, 4.25; cities <2 million popula-
tion, 2.79.  (13 references)

The investigations of Kehoe and Machle in the USA
over a period of 8 yr into the use of TEL contain-
ing gasoline as a motor fuel indicated that the
addition of TEL in the permissible proportion of
1:1260 was harmless to drivers and to the general
public.   Its addition was, however,  forbidden in
some European countries after the occurrence of
some cases of severe poisoning in 1924.
  The author has investigated the possible contami-
nation of the atmosphere by TEL and its  combustion
products, especially in crowded roads, by estimat-
ing the Pb content of the dust.   Pure TEL is never
used in cars and airplanes, but as a mixture with
ethylene halogens ("ethyl fluid"), so as to avoid
the deposition of PbO on the cylinders and to ex-
pel as much Pb as possible in the exhaust.  In the
presence of chlorinated and brominated hydrocarbons
pure TEL is decomposed into triethyl Cl or Br com-
pounds,  which volatilize at 800°C.  There is thus
no danger of injury from the vapor of TEL but a
potential danger from Pb dust and residues.
  The dust from the exhaust of an Opel car and an
army jeep was examined by passing it directly from
the exhaust on to a nitrocellulose film on the
slide of an electron microscope.  Numerous solid
globular particles, between 10 and 100 my in size
(av 30.6 my for the Opel and 35.4 my for the jeep)
with some aggregates, and a few larger white
flakes,  representing rust and oil, were observed.
A control experiment with pure gasoline showed no
globular particles.  Radiographic and microchemical
examination showed the presence of PbS04, insoluble
in water, PbBr2> soluble in water (^9'%)  and proba-
bly some PbO.  The total amount of dust in 1 m3
was 1.25-1.5 mg, and its Pb content 0.3-0.6 mg/m3.
This was a smaller amount than that of a chemical
investigation in 1950 when the Pb content was 8.3
mg/m3.  The difference is explained by  the fact

that in the filter method used in this investiga-
tion particles >5 my in size are excluded, suggest-
ing that the chief constituents of the dust are
finer than the granules observed by the electron
microscope, and this fine particle size may indi-
cate the danger of deposition in the bronchial
'systeia.  A comparison of the amount of Pb in the
dust of streets with automotive traffic and field
roads showed a content 100 times higher in the
former, but this was small in comparison with the
dust of Pb works and garages.  (The work here
described was performed by the "EMPA" (Society
for Testing Materials) for the Federal Leaded
Gasoline Commission of Switzerland.)

The author's conclusion in regard to the illness
affecting cattle and horses at pasture within a 5-
km radius of Pb and Zn foundries, is that the pecu-
liar clinical picture of the poisoning was due to
Pb in combination with another toxic substance,
probably Zn.   (Findings were described and summa-
rized by GUnther in his thesis published in 1954.)

Since 1947, Swiss gasolines contain ethyl fluids
as an anti-knock agent, consisting of (in weight
%):  TEL 63.3,  ethylene bromide 25.8, ethylene
chloride 8.7, and coloring matter 2.2.  One liter
of gasoline contains 0.4-0.6 ml TEL (or 425-640
mg "pure" Pb),  0.6 being the MAC in both Swiss
and German gasolines.  Frequently, gasolines also
contain ICA (o-tricresylphosphate) to reduce the
deposition of Pb oxide in the engine, and 0.02-
0.03 weight % of S.  It is estimated that only 15-
35% of the Pb contained in the gasoline is removed
with the exhaust gases, but according to investi-
gations carried out by the Shell Corporation, only
2-3% of the gasoline Pb is deposited in the engine.
Supposing a car uses 10 1. of gasoline/100 km, the
Pb deposit after driving it for 50,000 km would
amount to 1625-2125 g, which seems to be rather
high.  Pb content of the exhaust gases varies with
type of motor and is lowest during idling of the
motor.  Experimentally, an Austin A-30 car which
had run 15,000 km was powered with Shell supergaso-
line, Pb content of which was 530 mg/1.   Exhausts
were collected in a funnel and passed through a
cellulose filter, extracted with HNOj and dis-
tilled water and then colorimetrically determined.
Pb content ranged from 274-404 mg, indicating that
after burning 1,000 1. of a gasoline containing
500 mg/1, Pb deposit in the engine of this car
would amount to 96-226 g rather than 325-425 g, as
demonstrated by the estimation mentioned above.
Accordingly, in Switzerland, 165,000 kg of Pb in
form of highly poisonous Pb salts are given off
yearly by car exhausts.  In order to determine how
much of the Pb contained in inhaled air is retained
in the body, air samples of 100 1. each were taken
                in the following 3 rooms of a printing establish-
                ment:  melting room, type foundry and make-up room
                (used for sawing and planing the Pb).  In addition,
                exhaled air of persons working in these 3 rooms,
                also as 100 1. samples, was collected in glass
                tubes and then passed through cellulose filters.
                It was measured with a gas meter and determined by
                the nephelometer method, ie, measured as PbCrO^
                against buffered chromate solutions of known Pb
                content, maximum probable error being 2y.  The
                following concentrations of Pb were found in the
                air of the 3 rooms, in order stated above:  0.009,
                0.02 and 0.045 mg.  No Pb could be detected in any
                of the samples containing the respiratory air.
                It was concluded that all of Pb inhaled with the
                air is retained in the lungs of the workers.  In
                light of the constant increase of motor traffic,
                the latter fact is continually gaining importance.
                It is suggested that use of Pb-containing anti-
                knock agents  represents a growing danger  and  it
                is recommended that it be substituted by  Pb  free
                agents,  such  as benzol  in the  German  gasoline
                BV-Aral.

                ly.  Twenty-four rabbits (1.5 mo-old) were divided
                into 4 groups of 6 each.  Groups I, II, III were
                kept within 500 m from the factory for 3 mo, group
                IV was kept in an uncontaminated area.  All ani-
                mals received fresh tap water 2-3 times daily.
                Groups III and IV received food grown in uncontam-
                inated area; group II received food grown in the
                immediate vicinity of the factory but carefully
                washed before use.  Group I received the same food
                as group II, unwashed.  After 3 mo the animals of
                all groups were sacrificed, and the Pb contents of
                bones, liver and muscle were determined spectro-
                ^raphically.  Compared to the control group IV,
                the Pb content in these organs had increased as
                follows:  in group III, 3-1/2, 5 and 6 times; in
                group II, 5, 9 and 9 times; in group I, 20, 18 and
                27 times, respectively.
                  The author concludes that it is evident that
                most of the Pb had been ingested from the dust on
                unwashed food, followed by inhalation of contami-
                aated air, and only a minor amount had been ob-
                tained from contaminated soil by consumption of
                food grown on this soil.

BIOLOGICAL ASPECTS OF LEAD

         1:111-28,  1956.
 It was  established that gases after cleaning  with
 electric precipitators contain 1-2.2 g dust/m3,
 mainly  Pb oxides.   On recovery of  dust in wet
 chambers with  intensive spraying,  the gases dis-
 charged  into the  atmosphere contain 0.1-0.3 g
 Pb oxide/m3.   The  cause of  the incomplete recov-
 ery  of  Pb dust is  its high  degree  of dispersion,
 resulting in adsorption of  gases,  mainly  0, pre-
 venting wetting of dust particles.   Use of foam-
 forming wetting agents of the type DB and OP-10
 in concentrations  double those corresponding  to
 minimum surface tension  (correspondingly  0.15 and
 0.3%),  leads to instantaneous displacement of the
 adsorbed gas,  to  complete wetting  of dust parti-
 cles and to recovery of 99.7-99.9% of dust.   Addi-
 tion of a small quantity of Pb acetate to the
 solutions of wetting agents permits decreasing
 their consumption  to 1/3-1/4 without changing
 their effectiveness.  Film-type equipment is  re-
 commended for  dust recovery with the aid  of wet-
 ting agents.   Gas-stream velocity,  at a 27-30 erg/
 cm^  surface tension of the  spray solution,  should
 not  exceed the value corresponding to Reynolds no.
 4800-900,  otherwise turbulent flow of gases begins,
 leading to the breaking of  film and foaming of
 solution.  (From  Referat. Zhur., Met.  1957, Ab-

 The  use  of Pb  gasoline as motor fuel has  been per-
 mitted  in  Switzerland since 1947.   The  "ethyl
 fluid,"  added  to  the gasoline as an anti-knock
 agent,  contains (in weight %):  TEL 63.3,  ethylene
 dibromide  25.8, ethylene dichloride 8.7 and color-
 ing  matter 2.2.   In both Switzerland and  Germany,
 gasoline contains  0.4-0.6 ml of TEL or  425-640 mg
 of Pb/1.   In addition to soot and  gases,  the  ex-
 hausts of  cars running on such gasoline also  con-
 tain  PbS04, PbBr2,  PbCl2, Pb3(P04)2  and PbO.   Nu-
 merous  investigations have been carried out in
 order to determine  the Pb content  of exhaust  gases.
  In the study reported here, an Austin A-30  car,
 using 1  1. of  gasoline/18 km driving at 50 km/hr,
 was  chosen for a series of 5-min test  drives.  The
 amounts  of Pb  deposited on cellulose filters  in a
 funnel attached to  the exhaust pipe was determined
 colorimetrically with dithizone.    The values  found
 for  the  Pb content  of the exhaust  gases ranged
 from 274-404 mg Pb/1 of gasoline,  the difference
 being due  to the changes in speed.   During 1955,
 a total  of 540,978  tons of gasoline was imported
 into  Switzerland.   It is calculated that  at least
 200,000-290,000 kg of Pb have escaped into the air
with  the exhaust gases in the course of that year.
 The Pb contents of air samples,  taken at  various
 locations, ranged  from 5-7 ug/m3 of  air in down-
 town  Basel to 2-4  yg/m3 of air in a  village.   None
of the samples were  found  to be  completely  Pb-free.
In dust samples,  the following ranges  of  Pb  content
were detected:  from traces and  0.03 mg Pb  out  of
town to 0.2-1.2 mg Pb/g of dust  in  downtown Basel.
If each gram of dust, having the specific gravity
of 1.4, contains  0.6 mg Pb, each m3 will  contain
840 g of Pb.  It  is  stated that  the toxic effect
of Pb, when taken in through the lungs, is  10-100
times greater than when it is ingested.   The mini-
mum toxic dose for human inhalation of Pb has been
established at 100 yg/day.
   It is recommended  to discontinue  the use  of TEL
as anti-knock agent, or else to  reduce the  Pb con-
tent of exhaust gases by attaching  filters  to the
exhaust pipes in  order to  absorb the escaping Pb.

The study reported here followed a  publication  of
an article in a Swiss magazine on the  correlation
between the presence of exhaust  gases  and the In-
cidence of lung cancer.  Among various views on the
subject, in a personal communication,  Kehoe  stated
that there is no  relationship between  an  increase
of Pb in the atmosphere and the  incidence of pul-
monary carcinoma; that Pb  compounds have  been used
in the treatment  of  cancer; that there are  no data
indicating that exposure to Pb in industry  is ac-
companied by an increase in the  frequency of lung
cancer, and that  numerous  autopsy findings  on Pb
contents of lungs of persons exposed or nonexposed
to Pb show wide ranges, partly due  to  the differ-
ence in analytical methods.  Jecklin has  analyzed
lung specimens from  5 persons who had  died  of lung
cancer and from 5 persons  with normal  lungs, using
the colorimetric  method  (dithizone) as described
by Htigl and Sulser.   The results demonstrated no
differences in Pb contents.  The values found (in
mg/10 g of fresh  tissue) ranged  from 0.011-0.018
in the cancerous  lungs and from  0.010-0.016 in  the
normal lungs.  The conclusion was drawn that Pb is
not a carcinogenic agent.

The dispersion of suspended dust with high contents
of As was determined in the surroundings  of metal-
lurgical works processing Pb ores.   The potential
danger of such pollution of the atmosphere is dis-
cussed.  It is pointed out that health disorders
inside the factory as well as in its surroundings
are mainly caused by technical defects in the flue
gas cleaning devices.  (From Scientific Reports,

In the 1st phase  of  the study a literature  review
and extensive tabulations of  measured concentra-
tions of all pollutants found in surveys  were to
be related to broad  class intervals of population
increments and to the fuel and industrial economies.
Since most studies were planned to  deal with specif-
ic nuisances,  data related to fuel  and industrial
economies were too few to be statistically  represen-
tative,  rience a  new approach was tried for calcu-
lating pollutant  component concentrations,  using as
basic data published statistics on  domestic and in-
dustrial fuel consumption.   Finally, summary tabu-
lations of measured and calculated  pollutant con-
centrations were  prepared.   These 3 phases  are
shown in Appendices A,  B,  and C.   In Appendix A,
the Pb concentrations ranged from 0.10-42 yg/m3
(based on 40 references).   Pb was not included
among the substances for which calculations were
made.  In Appendix C, tables I-III  summarize the
literature data on measured air pollutant concentra-
tions throughout  the world;  in tables IV-V,  the cal-
culated concentrations for 7 metropolitan areas are
                given.   In Table  C-III,  the  average  and  range  of
                measured particulate  air pollutant concentration  in
                metropolitan areas  of >2,000,000, 500,000-2,000,000,
                and  <500,000 was  found  to be:  3.2, 0.23-4.5; 1.0,
                0.13-1.8; 0.65  yg/m3  respectively.   In Table C-VI
                the  average concentration of Pb  in air is  shown as
                0.0002-0.003 mg/ro3.   In Table  C-VHI, the  average
                concentration of  particulate Pb  (maximal loading,
                26.6 yg/m3) is  given  for 5 cities >2,000,000 as
                4.6  yg/m3; for  7  cities 500,000-2,000,000,  1.7;
                for  4 selected  small  cities, 0.9; and for  5 non-
                urban areas, 0.4.   In addition,  a synthetic atmos-
                phere was prepared  to test the viability of bac-
                teria on the basis  that since  "average maximum"
                concentrations  show no  detrimental effects on  the
                candidate bacteria, it  might be  assumed  that there
                are  no bacteriostatic or bactericidal substances
                in city air.  It  is admitted that this approach is
                not  a positive  solution of the problem.  The "av-
                erage maximum"  of Pb  for heavily industrialized
                areas was 4.5 vs  maximum concentrations  found  in
                3 cities, 4.5-42.4  yg/m3.  (38 references)

                The area under investigation was characterized by
                a  large number of sources of pollution and by the
                presence of 2 zones  of  discharge (the upper and
                the lower) as well as by a considerable irregular-
                ity of discharge of  waste products and by  the com-
                plex  nature of air pollutants,  fhe zones  with
                heaviest pollution,  for each separate industrial
                process, were situated  differently: 250 m  from the
                source of waste discharge in the production of red
                and yellow phosphorus,  500 m in the production of
                concentrated sulfuric acid, and 500-750 m  in the
                production of TEL and ethyl fluid.  However, pol-
                lutants in the case  of  TEL manufacture, or inor-
                ganic Pb and sulfuric acid were carried 3000 m, in
                the case of phosphoric  acid production, >1500.
                Tables show the results of analyses in air and in
                snow  for phosphoric  acid and S oxides.  In the
                case  of TEL manufacture, the concentrations of TEL
                in the surface layer of show amounted to an aver-
                age at 100-m distance of 57.7 mg/m  ,  and in the
                soil, 152; the corresponding concentrations for
                inorganic Pb were 4965.2 and 7750.  At 3000-m dis-
                tance, an average of 8.1 and 25 mg TEL/m   was
                found in snow and soil  and 8.1 and  190 mg  Pb/m  ,
                respectively.  TEL content near the inlet  of the
                ventilating duct within the factory was 0.192
                mg/m  ; at various levels of the platform;  at
                ground level, 0.063  (av), at 6-m height, 0.073,
                and at 19-21 m, 0.289.   In view of  these investi-
                gations, the author  proposes that  the MAC  of TEL
                in the air of working premises be  set at 0.005
                mg/m3 and in the  outside atmosphere,  at 0.0005;
                the corresponding concentrations of P compounds
                should be set at  0.15 mg/m3  (single exposure) and
                0.05  mg/m  average for  the day.

 The CO content in exhaust gases of several motor
 vehicles was found to range from 0.4-8.4%.  Elec-
 tromicroscopic investigations of the smoke showed
 the presence of spheric particles of a diameter of
 400 my that may be related to the presence of Pb.
 The average CO concentration at central street
 intersections was 28 ppm, in the center of the city
 21 ppm, in the environment of the city center 18
 ppm and at the outskirts 0.  In 2 tunnels the CO
 concentration ranged from 20-80 ppm.  The Pb con-
 centration in the air was 5.3-7.4 yg/1 in the
 center of the city,  3.6 yg/1 at a street inter-
 section near the center,  2.4 yg/1 in the outskirts.
 The Pb content of the street dust was 0.136-0.236%
 in the central streets, 0.08% in the peripheral
 streets, 0.048-0.052% at the sidewalks in the cen-
 ter and 0.044% in a courtyard.   The amount of Pb
 on the street surface varied during the day from
 1-8.1 mg/m3.   In 3 auto garages 0.8-10.6 mg Pb/m3
were found and in a testing shed for motor scooters
 7.5-17 mg/m3.   In a test performed on 20 urban
 traffic policemen, the Hb-CO was found to vary from
 0-10%, Pb in the blood from 30-65 yg/100 ml, Pb in
 the urine from 30-85 yg/1  (in one case blood Pb
was 90 yg and urinary Pb 130 yg), coproporphynuria
 from 0-3 yg%.     (40 references)

The principal sources are smoke from factories and
domestic chimneys, and the automobile exhausts.
(As concerns the latter, the composition of gaso-
line and diesel motor exhausts is tabulated, with
traces of Pb being present.)  Besides suspended
particles, S02, aldehydes and N dioxide are the
principal substances of practical importance.
Their additive action may produce irritation and
inflammation of the mucous membranes of eyes and
respiratory passages.  The level of Pb in polluted
air is immediately related to the density of
traffic.  In crowded streets CO may be present in
the air in concentrations of 0.002-0.004%.  Of
special interest are carcinogenic compounds present
in the exhausts of cars.  Reference is made to smog
disasters (Donora, London).  The damage to materi-
als produced by polluted air is pointed out.  Pre-
ventive measures are discussed.  (29 references)

Studies to determine the amount, composition, and
particle size distribution of Pb compounds present
in engine exhaust gases were made with laboratory
engines and with 2 conventional cars operated on
fuels containing TEL.  Exhaust carbon and organic
particulate matter were not investigated.
  About 20-30% Pb burned in the fuel was retained
in passenger car exhaust system deposits and lubri-
cating oil, 70-80% being exhausted over 20,000-
30,000-mile periods of city and country driving.
Pb emission was increased by speed.   Under city-
type driving conditions (idling, accelerating, de-
celerating, cruising) Pb recovered from exhaust
gas ranged from 20% of Pb burned when the exhaust
system was comparatively clean to as high as 60%
when the system was heavily deposited after exten-
sive light-duty service.  However, under sustained
high-speed driving conditions and during high-
speed full-throttle accelerations, the amount of
Pb exhausted was initially several times lower
than that burned but diminished in quantity as the
exhaust system became cleaner with continued
severe service.
  Exhaust particles ranged from 0.01 y to several
mm in diameter.  Particles <1y  were more numerous
but accounted for <5 weight % of exhausted Pb.
Heavy particles (i5y) represented ^27% of exhaust-
ed Pb under city-type driving, increasing to ^30%
under accelerating conditions.
  Pb was exhausted principally as PbCl-Br, a and
B forms of NH4Cl-2PbCl-Br and 2NH4Cl-PbCl-Br.  The
amount of Pb exhausted was proportional to the
concentration of TEL in gasoline, but particle
size distribution and composition were independent
of this variable.   The quantity of Pb exhausted in
particle sizes which might remain suspended in the
atmosphere appeared to be reduced by conditions
which produce low gas velocities and low tempera-
tures in exhaust systems (ie, design factors such
as larger engines and multiple exhaust systems as

well as operating factors).  That low-speed driv-
ing as encountered in congested areas tends to
minimize Pb emission, probably explains why analy-
ses of urban air show Pb concentrations which are
low in relation to the amount of Pb burned.

The Pb content of the air on various streets of
Zurich, Switzerland, ranged from 0.05-4.9 yg/m,
in the center of a tunnel it was 18.8 Ug/m3.  The
air in 8 garages contained 3.7-37.0 yg TEL/m3 or
2.7-29.1 yg Pb/m3.   In hangars and shops for
planes where tanking was done the air contained
5.5-300 yg TEL/m3.   Dust sediments on rural roads
not frequented by motor vehicles contained 0.000-
0.018/1000 Pb  while settled dust on city roads in
1948 had a Pb  content 100 times  as large.  The Pb
content in samples of settled dust collected at
19 different sites in Zurich during 1948-55
ranged from 0.10-7.0/1000.  Comparison of Pb con-
tent in settled dust showed in 6 samples taken
from Zurich streets an average of 1.4/1000, in 15
samples from 7 workrooms,  18.9,  in 22 from 11 ga-
rages, 16.1, and in 6 from 3 Pb  smelters, 303/1000.
Three series of tests were made with 6 different
persons while  the Pb concentration in the air and
the respiratory rate were varied.  Evaporation of
aviation gasoline was used as the exposure.  At a
Pb concentration in air of from 100-300 yg/m3 the
average Pb retention in the lungs and respiratory
organs at rest was ^58%.  During physical work
equivalent to  100 watt, retention rose to an aver-
age of 68.8%.   The results showed that changes in
Pb concentrations in air had practically no influ-
ence on the degree of retention, but that changes
in respiratory rate did.

Currently used German automotive fuels contain
0.07-0.08% S and a maximum of 0.06% by volume TEL.
During operation Pb-S compounds  of low volatility
are formed and deposited.  Deposits are most tena-
cious where metal temperatures are high.  A micro-
scopic study of the deposits on the cylinder heads
and exhaust valves showed the presence of Pb sul-
fate, Pb oxide, Pb oxide sulfate, smaller amounts
of metallic Pb, C, Pb halides and Pb oxyhalides,
occasionally Pb sulfide and more often Pb thio-
sulfate.  The Pb compounds were found in layers
that alternated with C layers.  If Pb and S com-
pounds are entrained as dusts in the combustion
air, and a nonleaded gasoline containing 0.02% S
is used, these compounds are preferentially con-
verted to Pb sulfate as the final product of a
sequence of reactions.  Fuels of different origins
did not differ in their tendency to form deposits;
however, deposition increased with an increase in
                the boiling range of the fuels.   (From Chemical

                Air Pollutants.  Ed. Ryazanov, V.A., Moscow,  1955.
                The author proposes  to establish  limits for maxi-
                mum single exposure besides limits for average
                daily concentrations of pollutants in air.  He also
                points out that adaptation to a poison does not
                mean that its harmful effect on the organism  has
                ceased.  Limits should be set according to the most
                sensitive index, ie, if a gas can be detected at
                concentrations below the toxic threshold, limits
                should be established according to the threshold
                of sensory perception.  S02 and Pb contamination
                is discussed in particular.  The  maximum average
                allowable concentration of Pb in  air approved by
                the All-Unlon State  Sanitary Commission is 0.7
                yg/m3.  This figure  is based on a MAC in drinking
                water of 0.1 mg Pb/1 or 0.2 mg/day.  Assuming that
                man inhales 15 m3 air/24 hr, the  safe concentration
                of Pb (by calculation) would be 0.013 mg/m3.  How-
                ever, since inhaled  Pb is more harmful than oral
                Pb, this figure must be reduced by at least 20
                times, ie, to 0.65 yg/m3.  Threshold industrial
                limit values for a number of contaminants are tabu-
                lated.  In measuring the dust content of air, the
                author does not recommend konimetric methods  since
                he maintains that the harmful effect of dust  is
                proportional to the  mass of dust  that penetrates
                into the organism and not to the  number of parti-
                cles.  Therefore, concentration by weight in
                mg/m3 and distribution of the particles should be
                measured, and MAC's  of dust in air must be ex-
                pressed in mg/m3 for various fractions of dust
                (size of dust particles).  The author objects to
                the method of sedimentation for testing air because
                man is exposed to the effect of suspended particles
                and not to those that settled on  the ground.  In
                the USSR restricted  zones from 1000-50 m are  es-
                tablished around industrial enterprises and no new
                plant may start operation without a permit from
                the State Sanitary Control which  tests its puri-

                in part with faggoted scrap.  The causes of the
                prolonged fusion process and the  increased con-
                sumption of crude Fe are to be found in the smoke
                issuing from  the furnace.  Among  the 17 mi-'tal-

                the slow melting, an intensive oxidation of non-

The total daily discharge of Pb from a storage
battery plant, equipped with precipitators, was
5.7 kg; from a Pb smelter, 14.7 kg.  Contamina-
tion of snow with Pb over a distance of 1000 m
from the Pb smelter was 10 times higher than
from the storage battery plant:  25.8 mg/m  vs
2.56 mg/m^.  The chromate micromethod  (Polezhaev)
was used for determining Pb in air.  Air samples
from the vicinity of the storage battery plant
showed in summer maximum daily averages of 0.0041,
0.003, 0.0023 and 0.0031 mg Pb/m3 at distances of
100, 300, 500 and 700 m, respectively.  Samples
collected in the area of the Pb smelter gave the
following maximum daily averages, in mg/m-*, in
summer, autumn, and winter, respectively:  at
100 m, 	, 0.0021, 0.027; at 250-300 m, 0.018,
0.0034, 0.039; at 500 m, 0.0048, 0.0022, 0.017;
at 700 m, 0.0053, 	, 0.015; at 900-1000 m,
0.016,	,	; at 1500 m,	,	, 0.0041.
  Twenty-one dust samples of 29 analyzed from
dwellings in the vicinity of the Pb smelter showed
presence of Pb, ranging from 0.012-0.03%.  The
artesian wells, used as water sources, contained
up to 0.0019 mg Pb/1.  Four hundred four persons
(18-50 yr  old and residents for >2 yr) living
within 1000 m of the Sn foundry and 147 persons
as controls from a distant area were examined.
The total incidence of disease in these 2 groups
was 136.2 and 46.3%, respectively, falling into
the following categories:  respiratory, 12.4 and
16.9%; nervous system, 50.2 and 6.3%;  cardiovas-
cular system, 38.9 and 19.3%; digestive system,
34.7 and 3.9%, respectively.  Urine samples were
taken from 78 persons (no data) living in  the
contaminated area and from 15 controls.  Sixty-
six samples of the first group contained 0.01-0.2
mg Pb/1 (25 of these showed 0.1-0.2 ing Pb/1).
The control samples showed physiologically normal
values (0.03-0.04 mg/1).  Four cats maintained
within 100-200 m distance from the Sn smelter
(where air contained av 0.0021-0.027 mg Pb/m3)  for
2, 3,4 and 7 yr and a control (4 yr)  showed the
following Pb content in tissues:  tibia, 120,  180,
1000, 2000 and 20 mg/kg; femur, 200, 260,  880,
1640 and 10 mg/kg;  brain, 300, 400,  140, 200 and
(-) mg/kg; kidney,  65, 125, 120, 70 and 30 mg/kg;
liver, 175,  90, (-), 150 and 70 mg/kg, respective-
ly-
  It is recommended that better controls be insti-
tuted for the removal of Pb from effluents; that
new construction and improvement of dwelling units
in a radius of less than 100 m from Pb smelters be
forbidden; and that a zone of tall-growing trees
be planted around the factory.

Although vehicular exhausts are a major source of
air pollution, it is not possible to conclude that
equivalent amounts of pollutant losses will pro-
duce equivalent effect in all cities.  This is due
to differences in topographical and climatical
situations.
  It is stated that the use of 1000 gal of gaso-
line releases 0.3 Ib of solids, which is a mixture
of Zn, Pb, other metallic oxides and C or that
every 1000 operating automobiles emit daily 0.6
Ib of this mixture.  This serious community prob-
lem will be brought to an end when a means for
substantially eliminating some constituents of the
exhaust is put to effective use.

The elaborate study described in this paper was
undertaken because passport and customs officers
had complained of symptoms at rush hours which
they attributed to exhaust gases from the running
engines of stationary motor vehicles.  Sections of
the paper deal with:  (1) The toxic constituents
of exhausts from petrol and Diesel engines which
include C0; N gases and aldehydes (a description
from the literature of the clinical effects of
these and of Pb dust from ethyl fluid is given);
(2) the movement of exhaust gases under different
meteorological conditions;  (3) the symptoms com-
plained of by officers at 2 frontier stations be-
tween Germany and Switzerland (a long list of com-
plaints of the officers and their frequency is
given and the most important were headache (48%),
a feeling of oppression in the gastric region
(8%);  (4) the traffic concentration at different
periods;   (5) measurement of the CO concentration
in the air;  (6) the association of traffic densi-
ty and CO content (this was examined at length by
statistical methods);  (7) statistical examination
of the relation between frequency of symptoms and
the traffic concentration and also the velocity of
the wind;   (8) the CO content of the blood of the
officers,  which was found to increase during work

  From the results of the study there is consider-
ed to be no doubt that the officers at these 2
frontiers are endangered by exhaust gases at times
of heavy traffic and when the air is still.   Some
recommendations are made for lessening this  danger
which arises not only from CO but also from other
constituents of the exhaust.

Author demonstrates the danger of Pb poisoning in
everyday life.  He reasons  that since man ingests
with his food about 200 pg Pb/day, the Pb content
in air should not exceed 12.5 yg/m3, considering
the fact that the inhaled portion of Pb is 10-100
times as toxic as the ingested.  He claims that
due to the use of leaded gasoline the limit of
tolerance has been generally reached and that for
instance in automobile repair shops it is often
considerably exceeded.  He states that in Switzer-
land 300,000 kg Pb are thrown into the air by
motor vehicles every year.  Although according to
authoritative statements no signs of Pb poisoning
have yet been noted, he questions whether the in-
crease of certain diseases which has been attribu-
ted to different causes, may not be a sign of
chronic Pb poisoning.  In discussing the fouling
of the air in Los Angeles the author calculates
that at a daily discharge of 10 tons of Pb into
the city air a yearly amount of 360 m^ pb is dis-
charged which corresponds to a "cube with sides
7 m long."  In view of all facts Pb should no
longer be considered as a trace element.  (29

                The authors investigated garages for the concen-
                tration of Pb in the atmosphere due to the use of
                TEL gasoline.  The average Pb concentrations  found
                ranged from 0-1.32 mg/m3, the admissible concen-
                tration of Pb, 0.05 mg/m , was surpassed 5-10
                times.  The state of health was not influenced by
                the use of TEL gasoline.  Simultaneously high val-
                ues of CO which surpassed the MAC 3-13 times were
                found.  Although so far no adverse effect on  the
                state of health has occurred it will nevertheless
                be necessary to require perfect ventilation of
                garages to keep the concentration of Pb and CO
                within permissible limits.   (From Excerpta Medica,

                A Commission was set up by the Department of  the
                Interior in Switzerland in 1947 to study the  ef-
                fects of TEL, officially permitted to be added in
                specified amounts to motor fuel in 1947, on the
                health of those who worked with the gasoline  and
                on the health of the general population.  Certain
                regulations were first introduced and these in-
                cluded general precautions in garages and in  the
                storage of the Pb-gasoline.  Gas containing TEL
                must be colored and its containers must be special-
                ly marked.  Its use for any other purpose than as
                motor fuel was prohibited.  A number of investi-
                gations relating to the subject have been carried
                out and reports on several of these have been pub-
                lished.  Reports of these studies are given in
                this paper with tables of results.  The data  so
                recorded are the TEL  content of various motor
                fuels in different years, the Pb content of ex-

haust gases, the Pb content of the air,  the extent
to which Pb in air or dust is retained in the lungs
when inspired, the daily intake of Pb from food or
water or inhalation of dust and gases and the Pb
content of the blood of medical students, garage
personnel and workers in Pb trades.
  The conclusion reached by the Commission, to whom
all cases of suspected TEL poisoning have to be
reported, is that no danger from the Pb  was es-
tablished except in isolated cases in workers with
airplane fuel, which contains much more  TEL than
does the auto gasoline.
  In the discussion which followed the presenta-
tion of the report the opinion based on  it was
that at present in Switzerland there was no Pb
risk and that, judging by the experience of other
countries, it was unlikely that a dangerous con-
centration of Pb in the atmosphere would be built
up.  Nevertheless, the continuation of control
measures is essential.  Some doubts about the
safety of the present state of affairs and anxiety
about the future were, however, also expressed.

As automobile exhaust gas has been implicated as
a major source of smog-producing chemicals, the
effect of TEL and halogen scavengers used in anti-
knock fluids was investigated.  Experiments were
carried out in 2 large reaction chambers equipped
with air-sampling systems, on 3 fuels, with and
without antiknock addition.  The schedule for
sampling and testing included physiologic measure-
ments in the form of eye irritation.  The 1st was
measured by sending 1 or 2 persons, from a panel
of 20, into each chamber at 9-min intervals.  They
stayed there 2 min, then indicated their reaction
on a questionnaire.  Typical smog symptoms were
found throughout the experiments.  Levels of eye
irritation ranged from zero to severe and large
amounts of oxidants were formed, ^40 pphm after
20 min.  The average levels of eye irritation were
low.  Statistical evaluation of the data from 48
individual runs showed no significant differences
as to eye irritation, aldehyde concentration, and
rubber cracking, as well as oxidant, hydrocarbons,
CO and NO's for the 3 chambers.  The authors con-
clude that additions of TEL to gasoline  do not
contribute materially to the Los Angeles smog
problem.

In connection with  the  planned increase in  motor
vehicles  (6th  5-yr  plan:  1956-1960)  the  problem of
air pollution  in  cities  compels  serious  attention.
With CO,  soot,  tarry  substances  containing  carcino-
genic components  (eg,  3,4-benzpyrine), N-oxides,
and TEL-containing  gasoline,  Pb  compounds are  emit-
ted.
  The data obtained on CO are first  presented  and
discussed.   It was  noted  that concentrations found
in city streets were  such that CO  pollution violat-
ed the sanitary living conditions  of the popula-
tion, and caused  changes  in blood  composition,
heacaches, vertigo, weakness,  etc.   The  suggested
MAC should not exceed  6 mg/m^ in single  tests  and
2 mg/m^ in av 24-hr tests.  Concerning Pb,  tests
showed that  Pb deposited  in the motor amounts  to
63% and the  remainder  escapes with the exhaust  gas-
es.  In burning 1 kg  Pb  gasoline an  idling  GAZ-51
motor discharged  0.3  g Pb; at a speed of 15 km/hr,
0.87 g and at 40  km/hr, 0.92  g.  Results of an  in-
vestigation  carried out in Sverdlovsk showed that
Pb content in exhaust  gases ranged from 0.069-3.70
mg/m^, in streets with heavy  motor traffic  Pb  con-
centration in air exceeded the MAC of 0.0007 mg/m^.
Pb was detected in  water  used by traffic police  for
washing hands, on outside and inside surfaces  of
windows and windshields of automobiles.  Large
quantities of Pb were  found on leaves of shrubs and
trees (up to 15.5 mg/m^).  In an investigation  car-
ried out in Moscow, from  0.001-0.003 mg/m^ was
found in street air.   Improvements of air condition
and prevention of further pollution  are suggested,
such as improvements  in motors, strict inspection
of engines, and discontinuance of use of TEL.

(mg/m^)  in leeward  direction  at a distance of
150-5,000 m from the plant averaged from 0.1212-
0.0068.   The corresponding values for S02 were
4.63-1.01 and for As,  0.062-0.008, respectively.
Air-dried loam soil in a distance of 500-16,000 m
from the plant, at  a depth ranging from 0-25 and
75-100 cm contained 4.1747-0.0778 and 0.0748-
0.0292 mg Pb/100 g.  For S02, 148.11-22.86 and
10.76-4.24 was found,  and for As, 1.882-0.305 and
0.196-0.007 mg/100  g.  Author  recommends measures

the use of TEL gasoline, the deposits contain Pb
and halogen derived from reactions in the intake
system, from blowback of the combustion chamber,
and from fuel residues carried by the crankcase
lubricant.  Multigraded lubricants prepared from
low-viscosity base stocks and containing viscosity
index improvers have a higher rate of deposit for-
mation than conventional lubricants.  The main
sources of deposits are apparently the high-temp-
erature oxidation products of the lubricating oil
base stock, and the amount of deposit formed is a
function of the amount of lubricant reaching the
valve underside area.

The Pb content of exhaust gases in Basel (accord-
ing to Jecklin), was found to be 2-7 yg/nP of air.
Since the Pb level in the blood of the population
is constantly Increasing, it is proposed to use
harmless antiknock agents.  The author discusses
various types of equipment to measure the exhaust
from various sources, so that measures can be taken
to prevent intoxication of man, animal and plant.

TEL and inorganic Pb are known to have an inhibit-
ing effect on enzyme actions.  The unconsumed
gasoline in auto exhausts contains unsaturated
hydrocarbons tending to produce smoke and aero-
sols of Pb compounds.  The question is raised
whether the absence of an increase in reports of
toxic effects from Pb compounds, while traffic
density continues to increase, may be due to un-
suitable diagnostic procedures.  Central nervous
system damages after exposure to TEL have been
reported to appear 14 yr after the original ac-
                cident.  Other known toxic substances found in
                automobile exhaust gases are CO and 3,4-benz-
                pyrene.  CO is known to block Fe-containing en-
                zymes and produce a decline in performance; 3,4-
                benzpyrene has been suspected to be at least par-
                tially responsible for the increased incidence of
                pulmonary cancer in town populations.  Among the
                unsaturated hydrocarbons in unburned gasoline are
                the olefins which under specific atmospheric con-
                ditions react with the ozone of the air  to produce
                the olefin ozonides, which are said to block
                enzymatic action because of the deflection of the
                active group.  Technical measures are needed to
                control air pollution, including better  utiliza-
                tion of gasoline to leave less unburned  fuel, and
                the use of catalysts to combat pollution with
                olefins.  It would also seem possible to exchange
                the Pb-containing antiknock compounds in gasoline
                with other compounds.  (From APCA Abstracts

Surveys were performed in Jan.-March 1955 and
March-June 1956, with 44 samples collected in the
residential and factory (non-Pb) districts and
main streets of Osaka from 10 AM-5 PM.  Collection
was by Greenburg impingers, and carried out at a
rate of 30 1/min for ^30 min.  Pb analysis was by
a modified polarographic method.  On one of the
main streets, the number of passenger cars, motor
lorries and small vehicles were counted according
to the classification of traffic statistics by
police.  The medians, the upper and lower limits
of Pb content in air were tabulated; the medians,
in yg/rn-^ were: residential districts, 4.5; non-Pb
factory area, 9.4; main streets, 10.2; same with
dense traffic, 36.4; average, 16.4.  The relation-
ship between Pb in air and the number of passing
motor cars during sampling ranged from 18.6 vig/m^
from 336 cars to 54.5 yg/m3 from 468 cars.  From
the results, the authors calculated the Pb intake
from the air as follows: by supposing that the
volume of inspired air by an adult/day is 10 in-*,
the Pb inspired would be 16.4 x 10 yg; since about
1/2 of it may be retained in the body, the daily
Pb intake from city air in Japan can be estimated
at ^82 ug/day.  (17 references)

Investigations of selected Moscow residential
properties indicated that of 1042 garages located
in this area and housing up to 10 automobiles, 66%
were distributed contrary to the sanitary clear-
ance regulation and 40% were in the immediate
proximity of children's and medical institutions.
While of itself this would affect the sanitary liv-
ing conditions of the population, the progressive
change to TEL-containing gasoline imparts to this
problem a more serious aspect.  It was also found
that in nearly all cases the garages occupied a
considerable part of the backyard, thus presenting
a constant danger to children's safety, and that
the exhaust gases penetrated into the apartments;
windows were also coated with resinous substances.
In the investigation described, CO was determined
in the air of garages, near the filling station,
in the air of apartments facing the filling sta-
tions and garages, and compared with findings in
apartments in the same building, but facing in
the opposite direction.  To eliminate the possi-
ble effect of household gas appliances, the lat-
ter were shut during sampling.  The greatest num-
ber of samples with CO >0.03 mg/1 was found near
the gasoline pump and in apartments located 18 m
from the pump.  A study of the Pb oxide content
in the air was conducted before the city trans-
port changed over to TEL gasoline.  As determined
by the sedimentation method in 204 air samples,
the highest percentage of samples with Pb >0.1
mg/m^ in 24 hr was found among those collected on
a busy highway and near a filling station.  It
was assumed that the Pb issued from cars using
TEL-gasoline.  The finding of Pb in the air of
nearby garages and apartments (values are not
indicated) was attributed to repair work using
Pb-containing solders.  The author concludes that
the heavy pollution in apartments indicates the
necessity of enforcing the regulation that filling
stations be located at prescribed distance from
living quarters.

were demonstrated at points where the traffic was
densest.  Attention must be paid to effects of
combined poisons and enzymatic damage.  Personal
studies on the amount of Pb in samples of grass
from the highways yielded values that must be
checked in various countries.  The values ranged
from 15,000 Pg of Pb/100 g of grass at the start
of the growing period to 100,000 ug of Pb/100 g
of older grass.  Pb is an enzyme poison.  (From

Limits of allowable Pb sulfide concentrations were
developed on the basis of determinations of actual
concentrations present in the air around a Pb ore
concentrating plant and studies of the effect of
exposure to Pb sulfide in laboratory animals.  The
concentrations of Pb ranged from 18.8 pg/m3 at a
distance of 250 m to 1.3 yg/m3 at 500 m; the con-
centrations of Pb-containing dust, from 1.24 yg/m3
at 250 m to 0.69 yg/m3 at 500 m.   Distribution of
the Pb sulfide was found to be influenced by wind
velocity and direction,  as well as by atmospheric
precipitation.  Analysis of Pb ore concentrate
dust showed that its toxic component was Pb  sul-
fide.
  Rats exposed to 48.3 yg/m3 of ore dust 6 hr/day
for 6 mo exhibited conditioned reflex shifts,
which differed with the typological characteris-
tics of the rat's higher nervous  activity pattern.
No shifts in higher nervous activity were observed
in rats exposed to 13.5  yg/m3 of  Pb sulfide.
Brain tissues of exposed rats showed the presence
of dystrophic changes in isolated ganglia cells.
No changes attributable to Pb poisoning were seen
in internal organs or blood.   It  is suggested that
the allowable 24-hr concentration of Pb sulfide be
set at 1.7 pg/m  and that the Pb  ore concentration
plant be surrounded by a sanitary clearance  zone
not <500 m wide.

                (2)   available data do  not indicate that  such
                change  would significantly increase the hazard to
                public  health  from air  pollution."  Should the in-
                dustry  increase  the concentration of  TEL, it is
                recommended  that:  "(1) the industry  proceed
                cautiously with  the increase so that  the  increase
                in  any  one  year  in the  TEL content  of US  pool  gas-
                oline not exceed  0.25 cc, and the concentration of
                TEL in  US pqol gasoline not be >3.2 cc/gal at  the
                end of  5 yr; (2)  the industry supply annually to
                the Public Health Service the domestic consumption
                figures for  TEL;  (3)  the Public Health Service,
                in  collaboration with the manufacturers of TEL,
                the petroleum  industry, and other appropriate
                organizations, conduct  studies to provide more
                definitive  data  on levels and trends  of atmospheric
                Pb  contamination in selected urban  areas  and of
                the body burden  of Pb of selected population
                groups.  If  these studies should bring to light
                new data of  significance, you may wish to recon-
                sider  the recommendation of this Committee."   The
                report  gives tables on  consumption  of TEL in USA
                for the years  1924-58 and estimated consumption
                based on 3-  and  4-cc  limits for 1959-63;  particu-
                late  atmospheric  Pb concentrations  in selected
                cities.  The technical  aspects and  advantages  of
                increasing  TEL  concentration are presented; the Pb
                exhausted (weight %)  in particulate size  ranges,
                Pb  retained by automobile exhaust systems and  lu-
                bricating oil  are tabulated.  The hygienic aspects
                are reviewed by  R.A.  Kehoe:  Evidence gained from
                surveys of  the Pb content of urban  atmospheres,
                general sources  of human exposure to  Pb,  experi-
                mental  studies  of the metabolism of Pb under ab-
                normal  conditions demonstrate conclusively that
                the contribution made by the TEL contamination
                of  the  atmosphere to  the total absorption of Pb
                by  the  American  population has been remarkably
                small  in either  relative or absolute  terms and
                that  it has been minute physiologically and in-
                significant hygienically, despite the tremendous

 increase in the use of  TEL.   During the past  11
 yr,  during  which the greatest expansion of TEL has
 occurred, there has been  no  sign  that  the average
 individual  in  the US has  sustained any measurable
 increase in the concentration of  Pb in his blood
 or  in the daily output  of Pb in his urine.  In
 considering the hygienic  effect of an  increase in
 the content of Pb in gasoline there is assurance,
 based upon  earlier experience and further investi-
 gations, that  the effects of the  proposed changes
 could be established in advance of any harmful con-
 sequences.

 At  this  Conference,  Pb  is mentioned briefly by L.A.
 Chambers in his  discussion of  "Where Does  Air Pol-
 lution Come From";  in that by  J.  Cholak,  "Can
 Standard Methods be Established for  Identifying
 and  Measuring  Air Pollutants";  in N. Nelson's
 "How Air Pollution  Has  Its Effects on  Health," and
 in R.L.  Chass's  "Extent to Which  Available Control
 Techniques  Have  Been Utilized  by  Communities  (1);
 Los  Angeles  County." In  the  latter, effective
 control  has  been achieved in  secondary  smelting
 and  associated  operations, including Pb,  con-
 ducted in the  County.   In the  discussion by L.A.
 Chambers on  "Transportation  Sources  of  Air Pollu-
 tion  (1) Comparison  With  Other  Sources  in  Los
 Angeles," the  author estimates  that  the use of
 1000  gal gasoline releases to  the air  among other
 constituents (CO being  the largest with 3200 Ib),
 0.3  Ib solids  (Zn,  Pb, other metallic  oxides and
 carbon); and every  1000 operating automobiles emit
 daily 3.2 tons  CO,  0.6  Ib solids  (Pb,  C, etc),
 among the various constituents.

The title subject is discussed because  of  the
 growth in importance of  particle  suspensions in
gases and in the atmosphere.   In  the discussion on
formation and classification, the  terms of dust,
smoke, fumes, mists, or  fogs  appear  to be  the most
 convenient in classifying particles of various
 sizes.  General properties (including a chart of
dispersoid properties),  stability, particle size
 and structure,  particle  size  statistics, resistive
 forces on particles and  settling velocities, nat-
ural electric charges and  conductivity, optical
properties,  and relation to gas cleaning processes
are the main headings under discussion.  Pb fume
 is included in a  table of  natural   charges  on some
representative dispersoids.

        41:344-7, 351 (Aug.), 1960.
Because of its  toxic nature Pb fume has become
 the subject  of  control legislation in most coun-
tries of  the world.  The Alkali Inspectorate
controls the problem of air pollution as it af-
fects the community at large.  The requirements
to control air pollution specify maximum concen-
trations and weekly mass emissions in inverse
ratio to the volume of gas discharged from a fur-
nace or chimney minimum.  Fully automatic filters
with properly designed ancillary equipment are
compact, labor-saving and highly efficient, but
their application to Pb furnace problems requires
careful appraisal because of certain factors pe-
culiar to this process.  Under the maximum oper-
ating conditions the total volume of gas entering
the filter, including the atmospheric air for
secondary cooling should be 5000 ft3/min at 100°C.
Estimated maximum dust concentration is ^1 ton/24
hr of which a useful proportion would be Pb oxide,
the remainder consisting of carbonaceous material
from the fuel and battery plates and dust from
the metallurgical additions.  The recovery effi-
ciency is up to expectations and the plant is now
operating satisfactorily.  (From APCA Abstracts

        Air Pollution Control Association 10:296,
        343 (Aug.), 1960.
In some areas the allowable emission discharge for
Pb permitted by air pollution statutes is extreme-
ly low, such as 0.00006 grain/ft3, -while in other
areas the tolerances are higher.  Consequently,
methods and techniques used for prevention of air
pollution vary in the secondary Pb plants through-
out the country.  Plants engaged in secondary Pb
smelting with either a blast furnace or reverbera-
tory furnace require an extensive system of air
pollution control.  Secondary smelting entails
treatment of scrap Pb storage batteries and Pb
residues which generate a heavy metallic laden
fume having an unpleasant odor.  These fumes have
to be filtered or cleaned.  The filtering of the
fume through cloth bags is the best accepted pro-
cess with a collecting efficiency of >99% of the
solids.  Other methods are also described.
  Where air pollution control is very strict,
emissions are first cooled to 250°F and then sent
into a baghouse which has woolen or synthetic
fiber bags.  The gas stream may be further treated
in an electrostatic precipitator to meet the or-
dinance requirements.  Measures of control of
pollution are discussed further in respect to re-
fining and alloying of secondary Pb, as is the
recovery of Pb from the discharges.

The report includes a chapter on Pb in which the
hazards of Pb intoxication are discussed as well
as routes, indices, MAC values, etc, of Pb expos-
ure.   On the basis of published data, it seemed
reasonable to allocate to air pollution exposure,
half of the allowable body burden, or ^45 yg/day
of absorption, in addition to that from food and
water.  Air analysis made by the California State
Department of Public Health gave the following

average Pb values for 1957 (yg/m3):  Berkeley,
1.04; Los Angeles, 4.30; San Diego, 1.34; Mt.
Hamilton, 0.12; the highest values were observed
during fall and early winter when low level inver-
sions and light winds are most frequent.  In con-
clusion, it is stated that a considerable amount
of data is  available on the toxicity of Pb, al-
though not sufficient to set a standard.  Since
relatively high atmospheric concentrations, compar-
ed with other cities, exist in LA, it is suggested
that average Pb levels of blood and possibly urine
of persons living in places with air pollution and
with known occupational and smoking history be
determined; also that balance studies be made in
LA, including Pb in air breathed, and the Pb con-
tent of autopsy materials be determined.

        SATURNISM IN THE VILLAGE OF MALO RUNDARE.)
        Higijena (Belgrade) 12:35-44, 1960.
A group of 107 individuals, mostly women and child-
ren,  living in the title village near a Pb-Zn
foundry (Trepca) was studied.  Analyses were made
of S02, inert dust, ZnO and Pb dust in the atmo-
sphere; of urinary coproporphyrin (CP) and Pb in
the blood and urine of the subjects.  The concen-
tration of S02 in air was 1 mg and of total dust,
3.4 mg/m3; at times it was >10 ppm.
  The effects attributed to S02 are first dis-
cussed.  Among the 107 inhabitants examined (of a
total of 114), 86% suffered from pharyngitis,  70%
from enlargement of the tonsils, 62% from conjunc-
tivitis, 33% from rhinitis, 10% from bronchitis, 3%
from bronchial asthma, and 2% from nephritis.   In
addition to this, the frequency of dermographism
was seen in 25%, Pb gingival line in 1%, hyper-
tension in 2%, and red cell counts of 4-4.5 mil-
lion in 21.8% and of 2.5-3.5 million in 78.2%.
The latter findings are discussed under the head-
ing of "communal Pb poisoning."  Overt signs of
poisoning were not seen, except for frequent com-
plaints of pains in body and dermographism, and
the frequency of tremor was not high.  In blood,
stippled cells were not found; Pb content, deter-
mined in 71 inhabitants ranged from 37-70.8 Ug%,
mean 49.38; the corresponding values for Belgrade
residents were 20-57.8 and 33.7; urinary Pb, 56-
301.8 yg/1, mean, 136.8; in Belgrade, 15-70.8 and
40.4; CP in urine, 9.9-109.8 yg/1, mean, 43.48; in
Belgrade, 3-66.6 and 28.88.  Aside from atmospher-
ic concentrations which ranged from 59-136 yg/m3
(mean, 117), Pb content in water ranged from 33-
63 yg/1, compared with 23 yg in Belgrade; in the
surface soil, Pb ranged from 86.0-222.1 mg%, mean,
141.1, and at 30-cm depth, 18.4-26.8 and 22.6; in
a Belgrade park, 0.35 mg%; in dust collected from
a roof, 252 mg%.  In analyses of animal products,
cheese made from sheep and cow's milk showed 132
and 124 yg%, respectively, while Belgrade milk
showed 10-15.5 yg%; onions contained in 2 samples,
0.580 and 0.784 mg% Pb.
  The results of the study pointed out to the
authors that care should be taken in establishing
industries near inhabited places, since many harm-
ful effects of factory effluents are not neutral-
ized at a distance of 1000 m.  They stress that
what can be tolerated under occupational condi-
                 tions, cannot be permitted under communal condi-
                 tions .

                 Investigations carried out in 1957 and 1958 by the
                 F.F.  Erisman Moscow Scientific Research Institute
                 of  Sanitation and Hygiene in cooperation with the
                 cities Tula, Chelyabinsk, Kuibyshev,  Perm, and
                 Gor'kii are described.   Samples were collected at
                 pedestrians' breathing level during  periods of
                 heavy traffic in an area where no  industries were
                 located, during the spring and summer of 1958,
                 but  only in the winter of 1957.  The K chromate
                 method was used and results were made on the basis
                 of  24-hr averages.  The  average concentrations
                 found in 1957 and 1958 were as follows in yg/m :
                 Tula, 140 and 0.24; Chelyabinsk, 3.86 and (not de-
                 termined); Kuibyshev, 0.36 and 0.68;  Perm, 1.90 and
                 below sensitivity of method; Gor'kii, - and 0.03.
                 The lower concentrations in 1958 are explained by
                 the  fact that a lower amount of Pb was added to
                 gasoline, and Pb-free gas was used in Perm.  In
                 addition, traffic directing personnel (^40 yr old)
                 at  points of heaviest traffic, 41 within the city,
                 and  44 outside the city  limits were  subjected to
                 rigid examinations.  Some manifested deviations
                 in  the nervous system  (vegetative  dysfunction) and
                 in  the cardiovascular system  (dystrophic and hy-
                 per- or hypotonic).  Blood pictures  showed reticu-
                 locytes and erythrocytes with basophilic stip-
                 pling; the latter were also seen in  the Chelyabinsk
                 personnel.  Deviations from normal functioning of
                 individual organs were found less frequently among
                 men stationed at city outskirts.   Of 2 men examin-
                 ed  while in the hospital,  1 had Pb poisoning de-
                 spite the fact that he had never been in contact
                 wirh Pb.  The author recommends that  the use of
                 TEL-gasoline be discontinued.

                 much more harmful effect than ingested Pb com-
                 pounds.  In mentioning Dr. Kehoe's publications,

                 that TEL, due to its high boiling point of 200°C,
                 does not evaporate together with the gasoline.

 Since in'the usual methods of determining atmos-
pheric Pb,  large  losses of Pb result from its ex-
 traction from filters or other collecting media,
 a method was developed to determine Pb directly
 in the filter.  Air is aspirated through an ash-
 less filter  (FPP-15) , converted  to PbS04 with
H2S04, the  filter is ashed at 500-550°, and Pb
determined nephelometrically as PbCr04 after solu-
 tion of the PbSO^ in NH^ acetate.  A motor, brand
 "Pobeda" was operated at various rates of speed
with TEL or Pb-free gasoline.  In both cases,  the
values for 0, H,  C02 and CO in the exhaust gases
were similar, but the TEL-exhausts contained a
 significant amount of inorganic Pb.  No TEL was
found in the exhaust gases or in the air of
 garages,  car barns  or  buses.   Exhausts  from an
 automobile, brand GAZ-51  showed  64-81%  Pb;  at
 the  speed of 15  and 30 km/hr,  1.4  g  Pb/hr was
 emitted.   Air in buses standing  in garages  or
 carparks  contained  up  to  0.1 mg  Pb/m^.   In  Tula,
 74 air  samples from streets with heavy  traffic
 showed  0.1-6.9 yg Pb/m^.  Recognizing the hazard
 of absorption of TEL through the skin,  10 samples
 of water  in which automobile mechanics  had  washed
 their hands were analyzed as to  total quantity of
 Pb,  deducting the value representing TEL and then

 lated of  actual Pb  and TEL found in  yg  (unit
 wherein determined  is  not given) were:  4-70 of
 Pb and  6.9-120 of TEL,  and in  one  exceptional
 case the  values were 290  and 2830, respectively.

The  following statement relating to Pb  is pre-
 sented  concerning standards for  ambient air quali-
 ty:   "It is clear that  Pb levels should be set on
 the basis  of average values for  long periods.
While data are abundant concerning hum^n response
 to 8-hr-a-day, 5-days-a-week exposures, data are
 insufficient for the effects of  the  continuous
 exposure inherent in community air pollution.
While laboratory studies will be pursued with
vigor,  it  becomes very  important that local agen-
cies collect data on existing Pb levels.  Since
Pb exposures are from  multiple sources, community
 air pollution standards should be based on  a por-
 tion of the total limit for population  exposure."

When  a dozen  families with a total of 58 children
settled  in  this  spot a few years ago, 14 of the
children soon developed chronic Pb poisoning, and
13 had fits which in 6 of them were caused by Pb
encephalopathy.  Analyses showed 0.15-0.25 mg Pb/
1 in  drinking water, and the soil contained 5.8-
9.5%  of  insoluble and 0.4-0.7% of water-soluble

The study of  the photochemical interaction of at-
mospheric pollutants includes investigations on
the effects of various nuclei sources on the for-
mation of aerosol particles in photooxidized ole-
iin-N02-S02 mixtures.  Besides the aerosol forma-
tion via the  S02 mode, aerosol growth from other
nuclei known  to be present in air was investi-
gated.   Pb-bearing nuclei resulting from the vola-
tilization of PbCl2 into moist air had no effect
in the absence of S02, but in the presence of 0.1
ppm S02, light scattering was suppressed, and the
number of countable particles tended to be great-
<_r, especially at low humidities.  It is concluded
that Pb-containing nuclei are prominent suspects
in the nucleation of aerosols in air contaminated
by motor vehicle exhaust.

Pb in a variety of forms is recognized as a poten-
tially toxicologic air pollutant.  Basic data-
collecting is being done by the Public Health
Service  in both engineering and medical fields.
Included in this program are studies of body Pb
levels on "high-exposure" groups to automobile
exhausts of leaded gasolines.  In the most recent
Rule No. 63 of the State of California on air
pollution standards for community air quality no
thresholds have been established for Pb as ad-
verse, serious or emergency levels due to insuf-
ficient  data.  Pb compounds are among the sub-
stances  proposed for revised USPHS drinking water
standards.

Data obtained from 60 analyses of Canadian soils
suggest  that  all normal  soils contain Pb, usually
at a level of between 0.5-5 ppm.   Soils over some
rocks may contain as much as 25-300 ppm Pb.  Pb
                 contamination of  the soil may result from mine
                 waste,  orchard sprays (Pb arsenate)  and exhaust
                 fumes of TEL.  Results of analyses of vegetation
                 at various  localities in Southern British Columbia
                 were divided into 3 groups according to their Pb
                 content (ppm in ash):  normal, ranging from av
                 8-39; moderately  anomalous, av 48-250; and strong-
                 ly anomalous, av  300-1600.  The last group con-
                 sisted of conifers growing within 100 yards from
                 a highway in the  Vancouver area.   The method used

                 The natural  radioactivity of rain at  Jassy in the
                 summer of 1961 was  investigated.  The samples were
                 always collected within  10 min  and then a fixed
                 quantity of  the  liquid was evaporated to dryness.
                 The g activity of RaB (21^Pb) and RaC was measured
                 with a thin-window  G-M counter.  The  specific ac-
                 tivity of the  29 samples measured varied between
                 0.88 x 10-11 and 10.11 x KT11  Ci/ml  with a
                 mean value of  4.02  x 10~H Ci/ml.  The effective
                 half-life of  the activity was 25-36 min.  It was
                 found that the specific  activity of rain is in-
                 versely proportional to  their intensity (as ex-
                 pressed in ml/cm2/min).   During rainfall there
                 was no systematic variation in  specific activity;
                 this indicates that the  main raindrop activation
                 mechanism occurs in the  cloud system.  (From Nu-

        8  (June) , 1961.
Since 1946, many determinations of the levels of
atmospheric Pb at various sites in a number of
cities have been made and an extensive and inten-
sive air monitoring program was carried out in
Cincinnati from January 1957 - December 1959.
Samples of airborne particulate Pb were generally
collected by electrical precipitation or filtra-
tion, and, later, by a staplex high volume sample.
The Hemeon or AISI smoke sampler was also used to
determine  the fluctuations of Pb in air during
successive periods of 1 or 2 hr.  Spectrochemical
and dithizone methods were used for the determina-
tion of Pb.
  For the  comparison of Pb in the air of cities
of varying population, only the samples collected
during comparable years (1954-55) were considered.
A total of 1229 samples from 24 cities, classified
by populations, were analyzed.  Of these samples,
700 were analyzed for the National Air Sampling
Network, and another 280 in Los Angeles during the
"t>mog" of  1954.  The cities represented in this
survey were:  Anchorage, Alas., Frederick, Md.,
Ypsilanti, Mich., <100,000; Chattanooga, Tenn.,
Charleston, W.Va., Salt Lake City, Utah, Tampa,
Fla., Elizabeth, N.J., 100,000-500,000; Atlanta,
Ga., Denver, Colo., Kansas City, Mo., Louisville,
Ky., New Orleans, La., Portland, Ore., 500,000-
1,000,000; Cincinnati, 0., Houston, Tex., Minne-
apolis, Minn., Washington, D.C., 1,000,000-
2,000,000;  Detroit,  Mich.,  Los Angeles,  Calif.,
New York City,  N.Y.,  Chicago,  111.,  Philadelphia,
Pa.,  San Francisco-Oakland,  Calif.,  >2,000,000.
The findings are tabulated along with the mean
and median concentrations.   In cities of 1-2 mil-
lion (M),  the mean concentrations in the air
ranged from 1.47-1.99 lag Pb/m3 while the median
ranged from 1.20 ug-1.42 yg Pb/m3;  those for
cities >2 M show that levels of Pb  concentration
were higher with respect to the range of values
as well as to mean and median values (2.85 with-
out L.A.,  4.28  with L.A.,  and 2.38  and 3.52,  re-
spectively; in L.A.  only 5.41 and 4.91).   The di-
urnal patterns  and yearly trends,  obtained from
around-the-clock monitoring at stations in
Washington, San Bernardino,  L.A.,  and Cincinnati,
which were considered representative at individual
stations, are shown in 2 graphs, and the frequen-
cy of occurrence of certain concentrations in Cin-
cinnati at all stations for the years 1946-1959
are tabulated.   From the overall results, the au-
thors conclude that contrary to predictions, a
downward trend in Pb values in air is noticeable.
The steady increase in the number of automobiles
and housing could be expected to produce higher
Pb values in air, but improvements in the quality
of fuels and enforcement of air pollution controls
as well as changes in traffic patterns due to
movement of the population to the outskirts, slum
clearance, infiltration of expressways, etc, are
among the factors causing lower Pb values in the
city air.   Analysis of the sources of Pb in air
shows that combustion of leaded motor fuel does
not account for all or even the major proportion
of Pb in air.  Other sources include Pb-containing
industrial dusts, the weathering of Pb-containing
products (paint, solder, bearings),  combustion of
coal, top soil at the sites of old built-up areas,
etc.  The general findings are not in agreement
with the predictions that the increased consump-
tion of leaded motor fuel will cause a proportion-
ate increase in the overall average Pb concentra-
tion in the air over expanding metropolitan cen-
cers.

The author emphasizes the danger of exposure to Pb
by inhalation and lists the following reasons:
The beneficial detoxicating action of the liver is
lost in respiratory absorption of Pb; Pb dust is
especially fine and penetrating; the absorption of
Pb by the intestine represents only 1/10 of the
quantity absorbed orally whereas by inhalation 1/2
of  the Pb absorbed is passed through th'e circula-
tory system.  Motor vehicle exhausts, responsible
for the pollution of the street air, release va-
pors of TEL in quantities sufficient to cause fre-
quent, unrecognized chronic Pb intoxication.
Therefore, the suppression of the use of Pb as an
additive in gasoline, and the adoption of protec-
tive measures on an international scale, are sug-
gested.

        (May), 1961.
The author'o discussion centers on the problem of
how automotive exhaust products may affect the
public health, considering the following:  The
chemical composition of automobile exhaust; some
past investigations; the possible irritating qual-
ities of these exhausts; the possible relation-
ship to lung cancer; the possible effects of spe-
cific substances (CO and Pb), and a few of the
current medical projects that are under investi-
gation by the Division of Air Pollution.  Among
the latter are extensive studies concerning the
range of blood Pb levels among a cross-section
of urban and rural populations.  Blood samples
were drawn from ^125 people in each of 8 cities
(New Orleans, Da'llas, Denver, Chicago, Cincinnati,
New York, Los Angeles, and San Francisco) and in
1 rural area in central Ohio, with subjects se-
lected from volunteers at blood banks in the var-
ious areas.  Another survey was of the blood and
urine Pb levels of ^35 employees of an automobile
inspection center in a large Midwestern city.
This was to provide conditions similar to the typ-
ical stop-and-go traffic of a city street corner.
Also included were 65 garage mechanics.  Aero-
metric measurements of the working environment
were made concurrently.  The above studies are
under evaluation.  Additional studies are planned
to include people with certain chronic diseases
and the very young to determine if they represent
populations more susceptible to the effects of Pb.
A study is also being conducted, aside from those
concerning CO, to determine the short-term ef-
fects of irradiated automobile exhaust on experi-
mental animals.

        THE ATMOSPHERE.   Journal of Geophysical
        Research 66:3227-31, 1961.
The activities of cosmic-ray-produced radioiso-
uopes, among them    Pb, arising from the decay of
radon, were measured in samples of dust filtered
from stratospheric and tropospheric air.  The iso-
topes are produced at widely different rates in
different regions of the atmosphere depending on
altitude and latitude and these characteristics «of
the production make it possible to use the iso-
topes to measure the time scales of air transport
from one region of the atmosphere to the other.
The uncertainty in the measurements (the error may
be as large as 20-30%) stems from the fact that
tne exact volumes of air sampled are not accurate-
ly known.  The purity of the sources was ascer-
tained from the characteristic y spectra of the
isotopes; that of 210pb from the growth of 210]3i
in them.  The results of the various measurements
are given in a table.  The activities of ^ Pb
were found to be O.l-u.2 dpm/10^ 1, and markedly
uniform.  The inventory of -10Pb in the strato-
ophere was of the order of 0.001 dpm/cm , which
is a very small fraction ("^0.01%) of the average
                 inventory  of  radon  in  the  atmosphere.   The  con-
                 centrations in  the  stratosphere  are  in general
                 higher  than or  comparable  to  those in  the  tropo-
                 sphere.  The  loss of 210pb from  the  stratosphere
                 occurs  by  the process  of decay and of  transfer  to
                 the  troposphere.
                   The concentrations as measured by  Burton  and
                 Stewart  (1960)  over England are  5 times higher
                 than in  the greater part of the  stratospheric
                 regions  over  the  US, which may be due  to some
                 local causes.

                 toxicity,  environmental, and  a clinical program.
                 In the  toxicity tests, the pure  additive (an or-
                 ganic Hg compound)  showed  the same order of  tox-
                 icity as TEL, but at the anticipated concentration
                 in gasoline,  it did not significantly  increase  the
                 toxic effect  of the gasoline.  In the  field  trial
                 phase,  the atmospheric sampling  program called  for
                 a  baseline study  prior to  the introduction  of the
                 new  fuel,  and a test period study after a steady-
                 state marketing level  was  reached.   Among  the
                 samples  and measurements considered  desirable
                 were air samples  for the determination of Hg, par-
                 ticulate Pb and CO, with the  last 2  to give  an
                 indication of the concentration  of auto exhaust in
                 the  air.   This  phase also  included discussions
                 with health officials.  In regard to the commer-
                 cial phase which was not started because of  tech-
                 nical reasons,  a  general program for evaluating
                 potential  health  problems  was presented.

                 The  public health problem  of  motor-fuel additives
                 such as  TEL and TML is discussed.  From what is
                 known of the  toxicity  of TEL, it is  clear  that
                 the  likelihood  of acute toxicity in  public  expo-
                 sure is  very  slight.   The  problem is therefore
                 one  of  chronic  toxicity.   Studies of Pb values  in
                 blood and  urine,  at occupational and non-occupa-
                 tional  exposures  should be conducted to resolve
                 this problem  without delay.

                 California is discussed.   It  is  similar to  that of
                 other states  in many respects but differs  in re-
                 quirements with certain problems, especially with

 on motor vehicles.  An orderly procedure  for
 dealing with  the problem has been developed.   The
 tables presenting  the standards  for  ambient air
 quality, established in 1959, show for Pb under
 the  column  'Vdverse" i^evel, not  applicable; for
 the  "Serious" Level and 'Vmergency"  Level, foot-
 note states:  "It  is clear  that  Pb levels should
 be set on the basis of average values for long
 periods.  While data are abundant concerning human
 response to 8-hr-a-day, 5-days-a-wk  exposures,
 data are insufficient for the effects of  the con-
 tinuous exposure inherent in community air pollu-
 tion. While laboratory studies will  be persued
 with vigor, it becomes very important that local
 agencies collect data on existing Pb levels. Since
 Pb exposures  are from multiple sources, community
 air  pollution standards should be based on a por-
 tion of the total  limit for population exposure."

 The  author  starts  his discussion of  the title  sub-
 ject by stating that the latest  news on air pollu-
 tion by motor vehicles stems from Los Angeles with
 the  1957 publication by Faith on photochemical
 smog.  In Italy, investigations  have centered  pri-
 marily around the  CO content of  urban air, as  pub-
 lished from 1956-60.  In a tabulation of 6 pub-
 lished surveys, Pb findings contributed by
 Giubileo (1957) for Milan were 2.4-7.4 yg/m3 in
 air  and 0.44-2.24  mg/g in dust.

 The  concentrations of Pb in a variety of foods,
 tissues, vegetation and manufactured products were
 measured by a microanalytical chemical method and
 data on human tissues obtained by spectrographic
 methods were analyzed statistically.  Pb values
 (yg/g of wet weight) in a variety of foods were:
 condiments,  0.0-1.5; sea food,  0.06-0.87 (mean
 0.49); meats,  0.0-0.57 (mean 0.21);  grains and
 grain products,  0.0-7.49  (mean 0.37); vegetables
 0.0-1.26 (mean 0.21);  fluids,  0.0-1.37 and 5-100
 Ug/1; cigarettes,  24.11;  spices,  0.10-0.64.   No
 obvious increase in Pb exposure  from foods or
 fluids during the last 20 yr was  demonstrated,  al-
 though airborne Pb had probably  increased.  How-
 ever, this  increment to the total body is usually
 small.  Analysis of potable water (yg Pb/1)  showed:
 tap water,  2.3;  spring,  0.0-112.5;  melted snow at
 the edge of  town,  0.0-77;  melted  snow on top of
mountain where auto exhausts gases were expelled
 for  5 min,  1858.  Tissues of various  animals con-
 tained (yg  Pb/g wet weight)  0.0-2.8  in liver;  0.0-
 26.17 in kidney; 0.16 in  bone;  0.15-0.20 in mus-
 cle;  0.2-1.71 in heart;  2.13-2.51 in aorta.   The
Pb level  (yg/g)  in vegetation was found to range
from 0.0-22.0 and  in some common  materials from
0.0-196.00.   The mean Pb  values  in adult human
kidney and  liver (261 samples)  from various  areas
of the world were  (ppm ash), respectively, 23-160;
20-213.   Levels in Africans were  generally higher
 than in other races.   The accumulation of Pb  with
age in tissues of American human beings in kidney,
liver, lung, bone, pancreas, and aorta demonstrated
a consistent pattern, reaching a maximum in the
5th or 6th decade.  In 4 tissues the highest mean
concentrations were 4-10 times those at birth or
in childhood.  Results indicate that daily amounts
usually ingested by American adults are much
lower than the limits set by Monier-Williams (0.40
mg) and Kehoe (0.35 mg).  The authors conclude that
Pb seems to be ubiquitous, that wild animals and
birds are exposed to it, and that probably it is
not an essential element; that Pb in human tissues
appears to come from natural sources and from in-
dustrial contaminants, although the proportions
from each source could not be estimated.  (34 ref-

It was pointed out at the meeting that air pollu-
tion by exhaust from automobiles is one of the
most serious problems.  A comparison was made be-
tween diesel engines and spark ignition engines;
both though different in quantity are identical
in quality of polluting agents.  The preventive
measures for both types of engines were mentioned.
The seriousness of the problem was illustrated by
an example where Pb-containing dust had caused
increased Pb content in the milk of cows grazing
on pastures along a highway.  Frequently the
calves of these cows could not be reared.  This
illustration was used to point out that there is
danger of pollution even where it is least ex-
pected.  The VDI Commission for Clean Air set up
a list of essential sources of air pollution,
which includes traffic, analogous to the list set
up by law for industries requiring a permit.

The preliminary investigation of the Swiss Commis-
sion on leaded gasoline, appointed on Apr. 11,
1947, to study the effect of TEL gasoline on pub-
lic health showed that the quantity of Pb in the
exhaust gases from cars varies much and amounts
to ^20-50% of the Pb present originally in the
gasoline.  It consists mainly of inorganic Pb
salts with traces of volatile organic Pb deriva-
tives.  It may reach much higher levels at higher
motor speeds since the Pb deposited in the exhaust
pipe is then swept off by the gases.  The Pb par-
ticles have a diameter which averages <125 my and
so behave practically like a gas.  These particles
are dispersed by the air currents and finally
washed out by rain.  The few larger particles
quickly fall to the ground.  It was shown that
these are only slightly soluble; therefore, the
hazard of water contamination is small.  The quan-
tity of Pb absorbed by the lungs av 60% of the Pb

present in the air.  The average city person,  with
no special exposure to Pb gasoline, takes up daily
20-30 yg of Pb from the air by breathing.  In con-
sidering reports of sickness cases allegedly
caused by Pb, the Commission found that of the 65
cases reported, in decreasing numbers over 8 yr,
only 35 were proved to be related to gasoline.
Of these 35 cases, 30 were caused by gasoline it-
3elf and only 5 by TEL.  In persons working with
Pb-containing gasoline, during 1955-56, the Pb
blood content was 22 yg% (range of 10-40 yg%)
against an average of 12 yg% (6-20 yg%) in those
who were not so occupied in 1955-J6-57.  Persons
working in the manufacture of Pb storage batteries
had a much higher Pb content, 61 yg% (5-155 yg%) .
A maximum Pb content of blood of 40 yg may still
be considered normal.
  In the streets of Zllrich, with intense traffic,
the Pb content of the air was 1.4 yg/m^ in 1949-
50 with an increase to 4.5 yg/m  in 1960-61.
These levels cannot be considered dangerous in
view of the levels of 100-150 yg/nH established
as limits for workers exposed to Pb.  In the dust
of the streets the amount was higher, from 0.052-
0.25% (1948-60).  Before Pb gasoline was intro-
duced, soil adjoining road contained 0.006% and
dust of rural roads, 0.0008% Pb.  The quantity of
Pb ingested with food was about 0.2-0.3 mg/person/
day in Switzerland and, under worst conditions,
the air from the streets contributed 0.03 mg/per-
son/day.
  It is concluded that TEL in gasoline has not and
is not currently endangering health, out that it
might become a problem since the Pb content in the
air is increasing as traffic increases and since
no substitute has yet been found for Pb in the
manufacture of gasoline.

clude supervision of commerce in Pb gasoline,

oilities of using Pb-free fuels, and removal of

Data are tabulated on the radioactivity in samples
of air, surface waters, milk, and foods collected
from various parts of the US.  The bulk of the
sampling was done during October I960, but some
data from previous months are included.  Results
are included on environmental levels of radio-
activity in the vicinity of 5 major Atomic Energy
Commission installations during the 2nd and 3rd
                quarters of 1960.  Factors contributing to the
                occurrence of radionuclide levels  in market milk
                are discussed.   Results are  included from a survey
                in Michigan of medical radiation exposure during
                pregnancy and measurements of  the  natural    Pb
                content of man.   (From Nuclear Science Abstracts

                Ethyl fluid added as antiknock to  automobile gaso-
                line contains 61.42% TEL and 35.68% ethyl bromide.
                In the process of combustion, Pb bromide is
                formed which is  by far more poisonous than TEL.
                The author concludes that the recent increase in
                heart disease and cancer may very  probably be due
                to the inhalation of exhaust gases of automobiles.

                The geochemical  aspects of Pb, Cu, Zn, Mo, Ag, Hg,
                and Cd in relation to health and the variations
                found in the soil are discussed.   As to Pb, analy-
                sis of 112 carbonate rocks from various localities
                in Southern Ontario showed that 75% of the samples
                contained 1-5 ppm Pb and 5-10% >25 ppm.  Vegeta-
                tion which concentrates Pb,  orchard sprays and
                automobile exhausts of TEL are considered as
                sources of Pb contamination  of the soil.  The
                author states that soils derived from rock may
                contain a much greater amount  of Pb than the orig-
                inal rock, and that vegetation can on occasion
                concentrate Pb by as much as 10 times the Pb con-
                tent of soil (ie, vegetables contained up to 700
                ppm Pb).  Samples taken near a highway contained
                unduly high amounts of Pb.   Trees  growing on a
                university campus contained  several 100 ppm Pb
                instead of the normal level  of 10-50 ppm.  A pos-
                sible relation between the amount  of Pb in the
                soil and the incidence of multiple sclerosis is
                suggested.  In areas where the incidence of multi-
                ple sclerosis was high, a different set of geo-
                logical conditions was found and a greater amount
                of Pb was present in  the earth's crust.  The
                author urges combined effort by medical men, agri-
                culturalists and geochemists,  to study the anomal-
                ous food supplies.

The difference between the quantity of Pb  found in
atmosphere in and around automobiles burning fuel,
containing either TML or TEL, was studied  with 4
pairs of foreign cars of which each pair of the
same make was run under  identical conditions and
the same period of time.  Samples of air were taken
for periods varying between 10-125 min.  Atmospher-
ic total Pb concentrations (vg/m3) , resulting from
TML- and TEL-containing  gasolines were, respective-
ly:  1950-8620, 1430-8160 in exhaust gas;  15-121,
18-138 in air under the hood; 8-107, 7-14  in air
at driver's seat; 16-44, 12-113 in ambient air,
4 ft behind the car.  Differential values  for the
quantities of organic, inorganic, and total Pb in
the atmosphere resulting from the use of TEL- and
TML-containing fuels were tabulated.  No signifi-
cant increase in concentration of Pb in air was
noted when gasoline containing TML was used, as
compared with atmospheric Pb concentration result-
ing from gasoline containing TEL.

Pb intoxication in 2 sisters, 18 mo and 6 yr  old,
respectively, and a brother aged 7 yr is de-
scribed.  The children lived in a house close to
a Pb foundry and played in a courtyard  which
probably was strongly contaminated with Pb oxide
dust.  The youngest child showed a typical Pb en-
cephalopathy and kidney damage; the 2 other chil-
dren had less distinct symptoms and no  affliction
of the brain or kidneys.  X rays revealed inter-
ference of the bone growth in the distal epiphysis

Attention is called to 2 papers (the 1st of 6)
that describe the comparative hazards of 2 organic
Pb gasoline additives.  The series is of interest
and of fundamental medical importance because the
investigations were based on the knowledge that
a measure of the toxicity and hazard of a rela-
tively new substance is a comparison of the bio-
logical activity of the material with that of a
related compound of known characteristics with
which there has been extensive experience.  The
article by Brief is a careful appraisal of the
concentrations of Pb in the air, produced in cars
using gasolines containing TEL and TML.  That by
deTreville et al provides a comparison  of the ac-
tual hazard of exposure to the compounds as well
as experience in routine monitoring of an indus-
trial production procedure, demonstrating the col-
laboration of medical and industrial hygiene sur-
veillance.  Finally, attention is called to the
fact that these investigations were carried out at
the direction of and with the support of the manu-
facturer or distributor, demonstrating the aware-
ness of industry of its responsibilities to the
public health and safety.

The literature on the biological effects of TEL is
briefly reviewed.  The previously used MAC of 0.15
mg Pb/m3 is considered to be invalid; instead, a
maximal allowable emission concentration, MEC, of
0.003-0.004 mg Pb/m3, applicable for the 24-hr day,
should be established.  Abolishing TEL as an addi-
tive to gasoline is advocated because of its possi-
ble harm to public health and because it appears to
be technically feasible.  Simultaneously, 3 other
toxic additives, ie, ethyl chloride, ethyl bromide
and tricresyl phosphate should be eliminated.

210pb activities and 210Bi/210pb ratios with corre-
sponding mean tropospheric residence times were de-
termined in 12 samples of rainfall collected at
Fayetteville, Arkansas.  210pb values ranged from
1.1-7.9 yyCi/1.  The mean tropospheric residence
time of 210pt> was 5.9 ancj 5,5 days and in agreement
with the mean interval of 6 days between 2 succes-
sive rainfalls in this area.  This illustrates
that 210pt>) formed by the disintegration of Rn in
the atmosphere, is efficiently captured by rain-
drops and removed from the atmosphere.

Porphyrin metabolism and urinary Pb excretion were
studied in 3 groups of children 4-7 yr old, 196
living in the neighborhood of a cable-manufacturing
plant, 111 from the vicinity of a Pb smelter and
100 from a control area.  Air samples were taken
from the 3 regions and the results of 24 hr Pb con-
centrations (yg/m3) were:  Control, 0-0.27 (av
0.27); cable plant, 0.56-1.93 (av 1.02); Pb smelter
1.39-3.61 (av 2.53).  The average CP concentrations

 in  the 8-hr urine of the children were:  6.5 ± 0.2
 for the controls; 8.2 ± 0.3 for those in the cable
plant region; 10.5 1 0.4 in the smelter region.
The data showed that continued residence in an
area of which the ambient air contains an av 24
hr concentration of Pb from 1.02-2.53 yg/m3
causes an increase in urinary CP elimination.  The
Pb concentration in 8-hr urine of 56 controls  and
54 children (both groups 5-7 yr old) in close
proximity to the Pb smelter were determined (200
ml was taken for analysis).   No Pb was detected
in the urine of 12 children of the test group  and
in 25 controls.  The concentrations for the con-
trols ranged from 0.01-0.03 mg/1 (av 0.015), and
in the 42 near the smelter,  0.01-0.05 mg/1 (av
0.023).  Only 1 of the controls had a urinary  Pb
level >0.02 mg/1 but 16 of  the test group exceeded
0.02 mg/1.  The author concludes that the results
confirm the validity of the official MAC of Pb in
atmospheric air.  (21 references)

Martin furnace dust amounts to 2-i kg/ton of
steel, 95% of the particles being 0.8-6 y in diam-
eter (av 2).  Martin dust is 25-30% Fe oxides,
40-bO% CaO, with smaller amounts of alkali metal
oxides, along with those of Zn, Pb, Mn, Si, P,  Mg
and Al.  In order to eliminate all visible fumes,
90-99% of the particles must be retained, leaving
<100 ug dust/m .  The proper design of vents,
hoods, flues, etc, can simplify dust collection,
by cooling and slowing down the escaping gas
streams.  (From Chemical Abstracts 58:9546, 1963)

Two aerometric studies, each lasting 1 wk, of  the
1.1-mi-long Boston Sumner Tunnel were conducted
in July and September, 1961.  Approximately 35,000
vehicles ply this tunnel each day.  The results
showed the following average concentrations: CO
in the tunnel, 70 ppm with instantaneous peaks as
high as 257 ppm; soiling index values in Cohs/1000

                 Extensive  study has been made of  some constituents
                 of the atmosphere, while other pollutants and
                 groups of pollutants have  been relatively ne-
                 glected.  Attention has been focused on  organic
                 pollutants,  but in  England  the major constituents
                 of total air solids are inorganic  in nature.
                 Amounts and  proportions vary according to season,
                 climate, and time of day,  while the industrial pic-
                 ture changes constantly due to the imposition  of
                 legal  restraints  and  the use of new materials.
                 The  objects  of the  paper were to  review  the pro-
                 portions of  pollutants  in  air in  relation  to as
                 many variables as possible and to assess the rela-
                 tive importance of  the  known constituents  in car-
                 cinogenesis  under various  conditions.  The  quanti-
                 tative analytical results  presented were averaged
                 for  1  yr in 1  place.  The  state of knowledge as  of
                 1961 regarding the  total air solids composition  of
                 the  atmosphere is summarized, with special  atten-
                 tion  to polycyclic  aromatic hydrocarbons,  As,  Fe,
                 Ge,  Pb, and V, which  were  plotted in air solids
                 against time.   There  was no annual cyclic  regu-
                 larity in  these pollutants, and,  from such  irregu-
                 lar  results, the  conclusions have no more  signifi-
                 cance  than that the ash-producing fuels  were some-
                 what variable  in nature and therefore probably
                 variable in origin.   In a  figure  giving  present
                 quantitative knowledge  on  total air solids, Pb is

The method and apparatus for crystalline iodine
collection of small amounts of TEL, TML, and other
prgano-Pb vapors from the air are described.  The
air is sampled at 1.5 ft3/min, for 1 hr.  Follow-
ing the collection of the samples in iodine, a
double extraction with dithizone is employed to
eliminate interfering ions.  The color of the fi-
nal extraction is measured spectrophotometrically.
The mean error for the combined processes of pre-
paring and recovering known samples of Pb within
the range of 1.5-4.6 yg Pb/m3 was 0.4, with a
standard error of estimate of 0.6 yg/m .
  Atmospheric organic Pb, measured in Los Angeles
from Mar.-Apr., 1962, ranged from 0.0-2.2 yg/m3.
The samples were collected in a 4-wk period from a
6th floor level window above an alley.  All sam-
ples were taken in the morning, except 5 which
were collected in early afternoon, in typical
spring weather.

        74-7, 1962.
A study was made of several new sampling methods
concerning the concentration of fine particles
and their Pb content in the exhaust of several
cars operated under cruising conditions and of the
effects of car, speed, and type of Pb antiknock
fuel additive on these concentrations.  Three
makes and models of cars, 3 speeds, 25, 45, and 60
mph, and 2 Pb antiknock additives (3 ml/gal of
either TEL or TML (3.18 g Pb/gal)) were selected.
Fine particle concentrations and concentrations of
Pb found in the fine particles per unit volume of
auto exhaust were not significantly affected by
variations in car, speed, TEL and TML fuel addi-
tives.  The average concentration of fine parti-
cles <2 u was 32 yg/1 of exhaust and the average
Pb concentration found in these particles was 13
yg/1 of exhaust.  The exhaust particulates con-
tained 62-80% by weight of particles <2 y under
cruising conditions: >68% by weight of the fine
particles were <0.3 y.  The average Pb content of
all particulate samples obtained was ^40%.  Vari-
ations in this value among individual tests re-
sulted from an interaction between speed and car.
This observation suggests a method for studying
the effect of car variables on particulate ex-
haust emissions, using Pb as a tracer.  The Pb
content appeared to be independent of particle
size when averages of broad size ranges were com-
pared.  This  observation can be utilized for esti-
mating the maximum contribution of auto exhaust
aerosol to atmospheric aerosol.
  In a discussion following the article, D.A.
Hirschler (Ethyl Corp., Detroit, Mich.) reviewed
some of his own studies (Industrial and Engineering
Chemistry 49:1131-42, 1957), the results of which
were not in as close agreement with Mueller's re-
sults as he would like to see them.  His work in-
dicated that from 1/2 to 2/3 of the Pb exhausted
under typical city driving conditions is <5 y and
^4-12% <1 y.  The fact that his results differ
from those of the present authors points out the
difficult nature of this type of work and the im-
portant effects that different approaches to parti-
cle collection and classification may have.  Al-
though the methods used by Mueller and coworkers
have much to recommend them, the difficult problem
remains of adapting these methods to driving con-
ditions which are entirely representative.  For
this, the problem is that of sampling.
  To this Mueller replied that Hirschler presented
data obtained from cars operated at a city driving
cycle and using a total sampling procedure fol-
lowed by sedimentation analysis of the particulate
sample resuspended in a liquid.  In contrast, his
data were obtained under cruising conditions using
size selective sampling methods.  Also the tests
were conducted on an all-weather chassis dynamo-
meter.  However, neither unrealistically high under-
car temperatures nor the sampling method could ac-
count for the differences in size distributions
found by the two groups of investigators.  Mueller
believes that his process of sampling minimizes
the risk of changing the nature of the particles.

In order to study the potential risks from gas-
olines containing TML or TEL, air samples were
collected over a period of >1 yr near 4 service
stations and in the streets at different distances
around motor vehicles.  Where TML-contalning gas-
oline was served, the atmospheric dust contained
3.32 and 3.6 ye organic Pb plus 3.90 and 3.82 yg
inorganic Pb/m3; with TEL-containing gasoline
these values were 3.15 and 4.04, and 4.25 and 4.79.
After 70 1. had been served, the ambient air con-
centration of organic Pb within 150 m3 ranged from
2.3-3.1 yg/m3 for TML-gasoline and 2.1-2.9 yg/m3
for TEL-gasoline.  Atmospheric Pb concentrations
contributed by exhaust gases =3 m behind ve-
hicles were 2-60 ug/m3 and 1-62 ug/m3, respective-
ly.  Pb levels of blood and urine were normal  in

animals (mice, rats, rabbits, etc) showed that
TML was somewhat less toxic:  LD^Q values in mice
weighing 20 g after 10 min exposure to TML or TEL
were 14.11 and 6.03 ppm, respectively; however,
animals died more quickly after TEL.  Aside from
this difference, there were some differences in
the symptomatology of the poisoning.  Changes found
in liver, lungs, kidneys and central nervous system
in acute and chronic intoxication were similar.
TML contains 77% Pb, TEL 64%; the vapor pressure
of TML is 60 times greater than that of TEL.  It
is concluded that no particular risk is created
when TML is used as antiknock agent in concentra-
tions of the same order as TEL.

        (Nov.),  1962.
The methods used in the USSR for the establishment
of MAC for a single exposure to  air pollutants are
discussed.  The 1st index considered is that of
levels causing reflexive reaction of the respira-
tory organs (including the nose) upon a single ex-
posure.  The method of optical chronaxy determina-
tion was used widely,  and correlated with odor
detection threshold.  As the chronaxy method
proved insufficiently sensitive, the procedure was
changed to the study of the visual adaptation to
darkness and light sensitivity.   In studying sub-
sensory reactions, EEC's are followed for deter-
mining rhythm assimilation.
  Application of these methods to various sub-
stances for which MAC's have been established is
discussed.  Among the MAC's those for Pb and its
compounds and of Pb sulfide (as Pb) are 0.0007 and
0.0017 mg/m3 during 24 hr, respectively.  In the
discussion, the author mentions that in the USSR
Pb is considered to be more toxic than in the USA.
Experiments with children in the USSR showed that
coproporphyrinuria and accumulation of Pb in the
bones occurred at exposure to 1 yg Pb/nH but were
absent at exposure to lower doses of Pb.

                                                      From 1959-1960 an investigation was conducted of
                                                      the effluents discharged by a Pb refining factory.
                                                      Fly ash emitted at stack height of 75 m amounted
                                                      up to 0.4 g/m-*, the Pb content of which was up to
                                                      0.2 g/nr'.  Aside from Pb, As and S gases were also
                                                      determined at various distances from the factory

                                                      The following average concentrations were found
                                                      at the factory site, at 0.5, 1, 1.5, and 5 km from
                                                      the factory, in mg/m3: Pb, 1.17, 0.22, 0.14,

                                                      at various distances from the factory brought
                                                      forth complaints of disagreeable odors by all who
                                                      lived within 2 km, and by 66% of those who lived
                                                      5 km away.  At a distance of 0.5 km, 75% com-
                                                      plained of dusts getting into their eyes; 100%

                                                      possible to air their dwellings.  At 5 km from the
                                                      factory complaints as to the latter were voiced by
                                                      only 19%.  Pb and As were also determined in the
                                                      soil at the distances stated above and were found
                                                      in the following average concentrations at the
                                                      surface and at 0.25-m depth, respectively, in
                                                      mg/100 g: Pb, 5546.6 and 3143.3; 1156 and 458;
                                                      613 and 430; 369 and 340, and 88.5 and 43.0.  As
                                                      concentrations ranged from 160 and 78.5 to 11.0
                                                      and 8.5 mg/100 g.
                                                        In order to determine the effects of such pollu-
                                                      tion, 5 groups of 6 rabbits each were placed at
                                                      distances of 0.5, 1, 1.5, 5, and 40 km from the
                                                      factory.  All rabbits were fed feed from a clean
                                                      area and given Pb-free water.  After 100 days the
                                                      animals were sacrificed and the organs were ana-
                                                      lyzed for Pb by a spectrographic method.  The av-
                                                      erage Pb contents, in mg/100 g wet tissue, were
                                                      as follows:  in bone, 10.9407, 8.2187, 3.8935,
                                                      3.2362, and 1.0799; in liver. 1.2870, 0.3863.
                                                      0.2293, 0.2202, and 0.0867; in muscle, 0.3547,
                                                      0.1816, 0.1319, 0.0572, and 0.0188.  On the basis
                                                      of these findings, the author considers that the
                                                      1-km protective zone specified in the regulations
                                                      for nonferrous factories is not sufficient, and
                                                      that no <5 km should be allowed.

 In this  report  the problem of  Pb  as air  pollutant
 is dealt  with on pp 141-8.  In order to  evaluate
 the public health  hazard  created  by  the  use of TEL
 and TML  as additives  in gasoline,  the  research
 conducted on  environmental levels of Pb, on animal
 and human exposure to Pb  and  its  accumulation  in
 tissues,  is reviewed.   It is  concluded that the
 maximal  atmospheric levels of  Pb  currently  ob-
 served have been much too low to  produce clinical
 evidence  of Pb  poisoning.  However, problems re-
 garding  the level  of  human tolerance to  additional
 continuous daily exposure to  Pb  resulting from
 vehicular and nonvehicular sources, remain  un-
 solved .

 The  Pb content of  some cereals and vegetables
 grown  in  various parts of Great Britain  and Brit-
 ish  Columbia was determined.   Average Pb values
 (ppm)  in  samples taken in British Columbia within
 300  yards  of  a well-travelled highway  and in Great
 Britain where they were either subjected to Pb
 pollution or  grown on  soils abnormally high in Pb
 ranged from 1-5 and 0.6-11, respectively.   Dry
 Ist-yr stems  of well known trees, collected at
 London suburbs where  traffic was  heavy,  and at a
 district  of Sussex, remote from automobile  traf-
 fic, contained 2-52 and 0.3-2.0 ppm Pb,  respec-
 tively.   It is suggested  that normal Pb  content  of
 food products, and of  leaves and  twigs of decidu-
 ous and evergreen trees (oven  dried), be  taken as
 0.1-1.0 ppm and up  to 2.5 ppm, respectively.
Higher  Pb values may be assumed to be abnormal,
 and to  have been caused by geological anomalies or
 by pollution.

 Pointing  out  first that it is not yet  possible to
establish definitely what pollutant of  the many
different combinations in the air of  cities are
responsible for causing  specific illnesses or ag-
gravating existing disease,  the Symposium organ-
ized by the WHO Regional Office for Europe, which
dealt with the problem of agreement on  measurable
indices of pollution and of  disease,  is briefly
reviewed.  Pb was included in the presentations
and discussions.

Data on poisoning in children and adults, caused
by common household and  industrial poisons, are
discussed.  Among other opportunities for poison-
ing, a number of cases of Pb poisoning  in the vi-
cinity of a factory emitting Pb fumes,  at La
Tablada, are mentioned.  After the occurrence of
Pb encephalopathy in an  infant, numerous other
cases of Pb poisoning in children and adults were
discovered.  A fetus originating from a spontane-
ous abortion and the placenta of the  dead mother
were found to contain large  amounts of  Pb.  Pos-
sibly this death was also due to Pb poisoning.

        TOXIC EMISSIONS  (GAS, SMOKE, AND DUST
        DAMAGE).)  Berlin, Paul Parey,  1963, 100
        pp.
The immissions of modern industrial civilization
and the resulting atmospheric pollution by gases,
vapors, smoke, fog, fumes, smog, dust and ash
causing direct and indirect acute and chronic mi-
croscopic and macroscopic damage and disease to
plant life are dealt with in great detail.   The
origin of pollution is of great importance in as-
sessing the potential damage to the vegetation.
It is recommended that the amount of  industrial
activities which emit harmful elements and com-
pounds be reduced to a nonhazardous minimum.  In
the case of Pb, the author conducted  tests in
which plants were exposed to dust containing Pb
carbonate, Pb oxide and Pb sulfate.  It was shown
that these metal dusts have little or no direct
or indirect harmful effect on vegetation.  Deci-
sive for any positive or negative effect of these
dusts,  besides the amount of dust and duration of
exposure, are environmental factors such as loca-
tion and surroundings and, of course, the condi-
tion of the plant itself.

Air samples were collected in the neighborhood of
a factory near the little town Fidenza, producing
TEL.  Analysis of 25 samples in the area adjacent
to the factory gave the following Pb concentra-

100-199 in 5, 50-99 in 6, 10-49 in 6, <10 in 1,
absent in 1.  In the residential area of the town
of 15,000 inhabitants the distribution and con-
centration of Pb was as follows: (yg/m-^ of air):
50-100 in 3 samples, 10-49 in 3, <10 or absent in
6.  Blood tests were made in 30 subjects who were
employed in 3 industries adjacent to the factory
for TEL or at the railway station close by.  The
Pb levels in the blood of these workers ranged
from 20.18-297.6 yg Pb (av 113)7100 ml, while in
14 control subjects not exposed to Pb inhalation
the corresponding values were 24.20-71.42 (av 53).
  The authors conclude that the concentrations of
Pb in air were greatly higher than tolerable, and
note that in US, recently proposed control programs-
provide for Pb concentrations ^5-7 yg/m^ of air.

The author sets out by stating that Pb poisoning
is as old as the human race, since it has existed
in the earliest antiquity through use of the metal
in cooking utensils, as sweetening agent (Pb ace-
tate),  cosmetics, and other applications.  He does
not mention the possible magnitude of the intake
from these sources but enters into just a brief
discussion of the possibility of Pb poisoning by
the use of TEL as antiknock agent in gasoline,
whereby "millions of tons of Pb are released year-
ly..." as much as "510 tons yearly in small Swit-
zerland..." (as calculated by Jecklin a few years
ago,  who found 850 g Pb/m  of street dust in
Basel).  He also points out that some, of whom
Kehoe is an exponent, oelieve that the threshold
limit of human tolerance has by far not been
reached whereas others emphasize that the blood-Pb
level has increased to the point that the toxic
limit of 0.06 mg% has by now been exceeded.  He
holds the economic and financial factors as play-
ing a role in the first complacent point of view.
He then reports two cases of Pb poisoning from his
own experience.  The first of these cases was that
of a chauffeur, referred to the author (a dentist)
by a physician friend of his.  The patient suf-
fered from a severe inflammation of the gums be-
sides having intestinal troubles, insomnia, fa-
tigue and pains in the joints and back.  He stated
that he often was aware of an odor of gasoline in
the cab.  After treatment with EDTA, the gingival
inflammation subsided and his general health im-
proved.  No blood tests were made because the au-
thor did not consider them as conclusive and be-
cause the costs would have been prohibitive for
the patient since no insurance would have accepted
a diagnosis of Pb poisoning.  The 2nd case was that
of the wife of a garage owner who suffered from
eczema.  Since there was a suspicion of chronic
TEL poisoning, EDTA therapy was tried and proved
successful.
  The author points out that pyorrhea is not con-
sidered as a symptom of Pb poisoning by the Swiss
Federal Commission of Leaded Gasoline although
Koelsch (1959), Cimasoni and Oltramare (1960)
have shown it as such.  He points further to Plet-
scher (1955) and others, who found that Pb levels
in blood were not always abnormally raised in mas-
                sive Pb intoxication and that the mobilization
                test with EDTA is indispensable for the diagnosis
                of Pb poisoning; to the fact that Pb is deposited
                in bone to be withdrawn from it years later by
                various illnesses, old-age degeneration, giving

                tions"; also to findings by a number of authors of
                an involvement of the vascular system in Pb poison-
                ing particularly so since recently it was shown
                that greatest deposition of Pb is in the aorta,
                as well as to a possible connection between mul-
                tiple sclerosis and chronic Pb poisoning.  The
                author further quotes the "Technical Reports of
                California Standards for Ambient Air Quality and
                Motor Vehicle Exhaust" in which it is stated that,
                assuming man inhales daily 15 m  air, the thresh-
                old for Pb in air should be set at O.U06 mg/m-*
                air.  This value is 25 times lower than the one
                established by Kehoe (1962).
                  In conclusion, by pointing to differences of ac-
                tion of inorganic versus organic Pb compounds and
                that inhaled Pb is 10-100 times as toxic as the
                ingested, the author demands that Pb-containing
                antiknock agents be forbidden and that legislation
                concerning Pb be revised.

                The toxicity of air pollutants is discussed  with
                respect to  the major differences between occupa-
                tional exposure which  generally occurs for an  8-
                hr period during 5 days/wk, with adult male  popu-
                lations, and exposure  of the general population
                which involves the young, the aged and the ill
                populations exposed to continuing exposure of  air
                pollutants.  Pb is one among a number of air pol-
                lutants discussed.  The MAC for exposed workers
                has been set at 200 yg/m  air.  The average  na-
                tional value of Pb in  the air has been reported
                as 1.4 yg/m-", with values ranging from 0.1 yg  in
                rural areas to ^3.5 yg/m  in populated areas.  The
                toxicity of Pb in the  atmosphere is greatly  in-
                fluenced by the particle size distribution.  Expo-
                sure to community levels of Pb is estimated  by
                comparing Pb levels in blood and urine in exposed
                and control groups, with higher levels found in
                urban residents and those with occupational  expo-
                sure to auto exhaust than in persons living  in
                rural areas.  Blood Pb levels >80 yg/100 g of
                blood indicated incipient Pb intoxication.   Addi-
                tional sources of exposure to Pb are cigarette
                smoking, food and beverage intake and occupational
                exposures.  Intake from these various sources  may
                in some cases result in increased Pb storage and
                chronic toxicity.  Further community studies are
                in progress.

BIOLOGICAL ASPECTS OF LEAD

-------
 For  this study  3  catalysts were  chosen  in  addition
 to the y-alumina  support, among  which chromia-on-
 alumina  (Cr-on-Al) proved to be  the most active
 both before and after poisoning.  The catalysts
 were subjected  to an amount of Pb corresponding
 to a 20,000-mi  trip using gasoline containing  3
 ml TtCL/gal.  The pure alumina catalyst  was  treated
 only with  the exhaust corresponding to  a 10,000-mi
 test.  Approximately half the Pb was deposited on
 the  catalyst; the rest probably  deposited  on the
 engine,  crankcase oil, and exhaust pipe, or es-
 caped into the  atmosphere.  The  Pb gradients were
 such as  to suggest that only a minor portion of
 the Pb escaped  into the atmosphere.  X-ray  powder
 diffraction analysis showed that the Pb deposits
 were in  the forms of PbSOi, PbSO,.PbO,  and
 Pb(Br,Cl)2.
  All the  catalysts were adversely affected by
 the Pb deposit.  The Cr-on-Al catalyst  was  least
 adversely  affected, requiring an increased  temper-
 ature of only 100°C  to maintain the same  conver-
 sion observed in  the fresh catalyst.  The  cata-
 lysts were relatively more effective in oxidation
 of isopentane than in oxidation  of CO.  Because
 the isopentane  is one of the hydrocarbons most
 difficult  to oxidize, it may be  concluded  that the
 catalysts  are considerably more  effective  for  the
 oxidation  of hydrocarbons than for the  oxidation
 of CO.

 Data are presented on the 210pb  content of  some
 biological specimens from the arctic;  lichens  from
 Finland and Alaska;  the stomach contents of some
 caribou; a Finnish water plant used for fodder
 (Equisetum flaviatile);  antler,  meat and bone  from

 first wet ashing the samples in nitric and per-
 chloric acids,  removing the nitrates by repeated
 fumings with HC1 and plating the    Pb decay prod-
 uct on a silver disk which was then a—counted.
 Concentrations  of 210pb in pCi/g dry weight were
 found as follows:   lichens,  8.29-61.2;  grass in
 Chicago, 0.128-0.819 (in decreasing order from
 root  to stem);  reindeer and  caribou meat,  0.174-

ment with available experimental data is rather

        of the Air Pollution Control Association
        13:314-21  (July), 1963.
The following topics are discussed: Air pollution
from plants engaged in the manufacture of Pb al-
tcyls; air pollution in connection with the trans-
portation, storage, and handling of concentrated
antiknock compounds; pollution of the ambient at-
mosphere of urban  areas with Pb alkyls derived
from the commercial distribution and use of leaded
gasoline as motor  fuel; pollution of the ambient
atmosphere of urban areas with Pb from the ex-
hausts of automobiles; Pb in the atmosphere of
American  cities;  sources of Pb in urban atmos-
phere; Pb in the environment of the American popu-
lation - absorption, excretion, and accumulation;
absorption and excretion of Pb under "abnormal"
conditions of exposure; standard for the quality
of air with respect to the concentration of Pb.
The discussion and conclusions are based on the
author's experience in industry and experiments
with human subjects.  Concerning the development
of a standard for  the quality of air with respect
to the concentration of Pb, based on above experi-
ments, " the available facts indicate clearly that
no public threat is posed by the Pb in our cities;
that we are able to recognize such a threat well
in advance of its  possible materialization," as
well as satisfactory experimental means for ob-
taining the information required to establish a
standard.  On present evidence the best that can
be done is to select some point between 75 ug/m
which is too high, and the range of 1-6 ng/m^
which is too low.  Kehoe cautions against ac-
cepting the written record of a number as being
authoritative at this stage and emphasizes the

As part of an intensive study by government and
private agencies the US Public Health Service
built an irradiation chamber facility for investi-
gation of irradiated auto exhaust under mixing
conditions similar to those in the atmosphere.
The facility consisted of a programmed continuous-
cycling chassis  dynamometer, an exhaust dilution
system, a dilution-air purification system, 2 ir-
radiation chambers, and exposure facilities.
Three variables  were considered:   (1) initial ex-
haust concentration (^13 ppm C and 35 ppm C),  (2)
average irradiation time (85 and 120 min), and (3)
fuel composition (14% and 23% olefins),  The ef-
fects of varying these test parameters were deter-
mined by use of  appropriate test criteria includ-
 ing N02 formation rate, oxidant production, total
hydrocarbon losses and reaction of specific spe-
cies, aldehyde production, plant damage, and bac-
 teria kill.  In the tests described fuels contain-
 ing 0.53 and 1.38 ml TEL/gal were used.
  Of the 3 variables studied during the 1st test
series, the exhaust concentration at the start of
irradiation appeared to produce the most signifi-
cant effects.  Fuel composition had a lesser in-
fluence.  Very little difference was noted in the
effects produced at 2 different average irradia-
 tion times.

        1963.
In the area around King Baudouin Station (70°
South, 24° East), it is shown that a reference
horizon, easy to identify, was formed by the
stratospheric fallout of radioactive debris from
thermonuclear bomb tests.  Gross g-activity and
  Sr were measured in snow and firn samples from
1935-1960.  The contribution of natural  radionu-
clides is negligible, and the gross g-activity
can be taken as a measure of the fission-products
concentration.  A sharp 10-fold increase in the
g-activity at the beginning of 1955 is attributed
to the sudden release in the Antarctic troposphere
of fission products from the Castle thermonuclear
tests series  (March, 1954).  The previous and 1st
thermonuclear test (Ivy, 1952) is less marked.
The g-actiyity before 1952 is essentially due to
   Pb and   K.  There are indications that this
radioactive horizon has been formed at the same
time over the whole ice cap, but direct checks are
needed on more, well-dated firn profiles.  (From

        POLLUTION—FACTS AND FABLES.  Journal of
        Occupational Medicine 5:461-7 (Oct.), 1963.
The author points out that air pollution problems
cannot be remedied without a reasonable under-
standing of both environment and man.  Before any
activity can be instigated to eliminate  this pol-
lution, one must have facts that define  the char-
acteristics of a clean atmosphere and concerning
which most reasonable persons can agree.  This can
be accomplished only when facts and their inter-
pretation are not confused with fables.  The au-
thor discusses 8 fables of air pollution.  Fable
No. 7, in which Pb is mentioned, is:  "The automo-
bile is wholly responsible for our unclean air.
Many well and poorly defined materials are emitted
from engine exhausts, and the population is being
poisoned in some insidious fashion."  To show the
unreasonableness of this statement, the author ex-
plains that few pollutants have been studied as
extensively as automobile exhausts, the  chemicals
emitted therefrom being products of gasoline and
its additives.  One additive, Pb, is well known
and its action understood.  Quantities of Pb in-
troduced into the atmosphere from automobile ex-
hausts have been proved insignificant through
clinical and laboratory data.  The author further
states this does not mean, however, that automo-
oile exhausts do not contribute to air pollution,
but it does mean that all the facts are not known
yet.  (40 references)

analysis procedure was similar to cumulative sedi-
mentation methods of particle size determination.
On the basis of data obtained for field samples
in the San Francisco Bay Area and the Los Angeles
basin, a typical size distribution for the Pb
aerosol would be one with a mass median equivalent
diameter of 0.20 p with 257, of the mass being ac-
counted for by particles with an equivalent diam-
eter of <0.1 p and another 25% of the mass in par-
ticles >0.3 u-  ihe principal source of the Pb
aerosol in these tests was automobile exhaust.
The various compound constituents which make up
the atmospheric Pb aerosol could not be deter-
mined.  The fraction composed of water-aoluble
compounds averaged a solubility from <1-18%.  The
data indicate that the more soluble Pb salts such
as the chloride, bromide and sulfate are probably
minor constituents of the Pb aerosol.

The author reviews in part a paper by A.S. Zykova,
(1957), pointing out the following facts:  that
Pb was found in the USSR in 73-79% of all air
samples collected in the vicinity of a storage
battery plant and a tin smelter, the discharge
for these 2 industries amounting to 5.7 and
14.7 kg/24 hr, respectively.  The average Pb con-
centrations in the atmosphere at distances of 500-
700 m from the battery plant were 3-4 times higher
than the MAC of 0.0007 mg/m3, and at a distance of
1500 m from the tin smelter 5-6 times higher.  The
Pb penetrating from the outside air into dwellings
exceeded the MAC 3-5-fold, and concentrated in the
dust as found by analyses.  People who had lived
for some time in a Pb-polluted atmosphere showed
a tendency to a higher incidence of diseases of
the digestive, cardiovascular and nervous system,
as compared with a control group.  In many cases,
their urinary Pb levels were indicative of Pb
absorption.  Analyses of tissues of chickens
demonstrated that Pb accumulates in the organism.
  The reviewer points out Zykova's recommendation
that protective zones around the Pb-discharging
plants be created, and states that this had been
considered in the German Federal Republic, but
has not yet been realized.  He goes on with a re-
view of a paper by the German authors Drummen and
Reinl (1962)  who reported Pb poisoning in 3 chil-
dren who had lived in a house close to a Pb foun-
dry.  StHfen reports an additional case from his
own experience which occurred in a child living
close to another Pb foundry.  The child had a Pb
level in the blood of 100 ug%,  urinary CP of 520
Mg% and displayed the characteristic brain in-
volvement.   Although SttiTen wonders why Zykova
did not investigate the health of children and of
persons >50 yr old, her investigation does point
to the fact that the risk of Pb poisoning in a
population living in areas where Pb is discharged
is much greater than previously expected.  The
electrofliters mentioned by Zykova are not used
by many Pb smelters in Germany which lack even
effective control of the S effluents.  From the
economic standpoint it does not appear possible
to apply the Soviet MAC values for residential
areas or to establish protective zones.  Stiffen
suggests that the Department of Public Health of
the German Federal Republic investigate the ex-
tent of the health hazards.  In order to avoid
apprehension on the part of the people, such
studies (blood and urine analyses) should be car-
ried out by the Sick Funds in an inconspicuous
manner.  This might involve a change of the Feder-
al compensation laws (RVO).  Furthermore, all
suspected cases should be reported.  Since Pb
salts are used as abortive agents, the possible
effect of Pb effluents on the fetus should be
investigated.  Effects by effluents of Pb smelt-
ers, juch as acidification of the soil by S02 and
Pb accumulation in the soil with all its implica-
tions, effects on forests, all plants, domestic
and wild animals aside from man, are mentioned.
Emphasis is laid on the need of protecting the
child and the embryo.  It is also indicated that
workers of Pb foundries live as far away from
their work as possible so that they are not ex-
posed to Pb also at times when they are away from
work.

Samples of Atlantic and Mediterranean waters were
obtained from 5 stations and at various depths from
each station.  Snow was collected from the Lassen
'Volcanic National Park and Pb was determined by an
isotope dilution procedure.  The Si02 content of
the snow samples was also determined and used as
an index of the silicate dust concentration.  At
depths from 2725-5134 m, Pb concentration in sea
water ranged from 0.02-0.20 ug/1.  Measurement of
the isotopic composition of Pb in snow gave the
following ratios:  206/204, 18.01; 206/207, 1.144;
206/208, 0.469.  In discussing the results and the
sources of Pb, the authors conclude that amounts
of additional Pb introduced into oceans by agri-
cultural activity is only ^1/10 of Pb contributed
by TEL and other industrial Pb compounds.

As discussed by Patterson, unfiltered samples of
sea water taken off the coast of S. California
show an abrupt decrease in Pb concentration from
surface to deep water.   Sprface water Pb cones
ranged between 0.1 and 0.4 yg/1.  Deeper waters
had Pb cones of 0.02 yg/1.  The origin of the high
surface Pb concentrations is discussed in terms of
run-off of rivers and is attributed to mining and
processing of Pb for TEL which is converted to
aerosols with ^100% efficiency, thus finally reach-

        CONCENTRATION OF COMMON LEAD IN SEA WATER.

Pb was determined in sea waters off southern  Cal-
ifornia, using isotope dilution techniques.  Sam-
ples were collected in 100-1 stainless steel  car-
boys with teflon and polyurethane seals (Pb con-
tent of the latter, <5 ppra).  Care was taken
against contamination during handling.  In surface
waters, the concentrations of dissolved Pb varied
from 0.4-0.08 yg/1, with an average of 0.2 yg/1.
In deep waters, the concentrations did not vary
much about an average of 0.03 yg/1.  Assays of
the particulate matter showed that Pb may be  about
equally distributed among dissolved and particular
forms in sea water, so that the total concentra-
tions of Pb may be about twice the values found
for dissolved Pb.  A diagram of the Pb profiles  in
sea water illustrates the abrupt decrease in  con-
centrations from surface to deep waters.  Pb  con-
centrations in the surface waters increase in
going away from the shore.
  In discussing the results, the authors conclude,
on the basis of their earlier estimates, that the
present rate of introduction of Pb to the oceans
is 27 times greater than at the time of Pleisto-
cene.  The reason for this increase they believe
to be the accelerated chemical denudation of  soils
in agriculture by man, and by the mining of Pb and
the converting of it into paints,  insecticides, and
fuels.  The industrial contamination has become
important during the last 50 yr.  In their calcu-
lations, in the last 3 decades, exhausts of Pb
from automobiles as burned TEL has increased  in
the US from zero to ^1.6 x loll g Pb/yr.  Since
the conversion of TEL in gasoline to atmospheric
aerosols is ^100%, the total amount of Pb intro-
duced to the atmosphere in the northern hemisphere
as burned TEL has increased from zero to 3.5  x 10-1-1
g/yr.  This amount is washed out by rain each year,
2.5 x lO^ g/yr falling directly to the oceans and
the remainder on land where a portion of it enters
the oceans as river runoff.  If all industrial
sources are counted together, the present annual
input of Pb to oceans of the northern hemisphere is
43 x 10!0 g and the input for the entire earth is
about 46 x 1010 g/yr.
  The input of Pb from all sources is shown in a
diagram.  Evidence suggests that Pb entering  the
surface layers of the oceans is quickly ingested
by living organisms and a part, estimated to  be
2 x lOH g/yr, is transported from surface waters
to sediments by means of biological material  serv-
ing as a carrier.  Based on estimation of the
rate constant for the biological removal of Pb,  a
half-life of 7 yr can be calculated for Pb in sur-
face waters.  If the values estimated for the re-
moval constant, the preindustrial surface concen-
tration, and the present rate of introduction  of  Pb
are used to predict its present concentration in
surface waters, a value is obtained which agrees
closely with the observed values.  (25 references)

                As stated in the introduction, the major factors
                that determine the body burden of absorbed pollu-
                tants involve the chemical nature, size and physi-
                cal state of the material, the portal entry into
                the body, the chemical and physical interaction
                within the body tissues, utilization and damage
                or interference with normal mechanisms, and the
                excretion from the body either of the original
                product or of metabolites.  Pollutants may enter
                by absorption through the skin, inhalation, or in-
                gestion, although skin is not ordinarily an im-
                portant route in this case.  Illustrations of the
                transport of particles, lung deposition and reten-
                tion of several substances are included.  Refer-
                ence to Pb states its metabolism to parallel  that
                of Ca.  In closing, the author draws attention to
                the fact that the true estimation of body burden
                for any individual pollutant requires comprehen-
                sive study of multiple parameters.

                Some recent investigations concerning the atmos-
                pheric concentration of Pb are reviewed.  Observa-
                tions made in 1941 at a number of sites in Cincin-
                nati yielded an average Pb concentration of 5.1
                yg/m3.  Analysis of samples from 24 cities in the
                US during 1954-1955 yielded a mean  concentration
                ranging from 1.47-1.99 yg Pb/m3, while median
                values ranged from 1.2-1.42 yg.  Cities with a
                population >2 millions had significantly higher
                mean and median values; Los Angeles had the high-
                est mean level of concentration.  Air over heavily
                traveled streets contains more Pb than does  air
                over lightly traveled streets and considerably
                more than ambient air of representative large
                areas at the community.  Average daily and hourly
                patterns were established.  Distinct peaks were
                observed in the 4-hr period of 7 AM-11 AM; other
                peaks appeared in relation to increases in motor
                traffic and domestic and industrial activity.  In-
                vestigations carried out in Cincinnati from 1941-
                1962 portray a continual and gradual downward
                trend in both mean and median concentrations of Pb
                in  air.  The mean concentration of  5.1 yg/m3 in
                1941 decreased to 1.43 ug/m3 in 1962 while the
                median level fell to 1.27 yg in 1962.  After 1954,
                no  concentration >8 yg/ffl3 of air was found.  It is

ranges found from 1941-1951 may be partly due to
the manner of sampling during this period, and
therefore may be somewhat biased, while today con-
tinuous monitoring over 24 hr is more representa-
tive.  The decrease in atmospheric Pb is attribut-
able mainly to a spread of motor traffic in cities
over a larger area along with the spread in hous-
ing.  Also, the mean concentration of particulate
matter found in the air in 1961-1962 averages only
0.082 mg/m3 as compared to 0.37 in 1946-1951.  Lead
alkyls may be detected in the air in certain areas
of gasoline service stations, and occur at times
over heavily traveled streets.  Most of the find-
ings (in filling stations) were within the range
of 0-3.5 yg/m3 air.  The error of analysis is
greatest when small volumes of air are sampled be-
cause the Pb values are near the limit of detec-
tion.  Sampling of adequate volumes of air in Cin-
cinnati yielded average amounts of 1.1 yg Pb in
the form of Pb alkyls, which approximates 10% of
the total Pb.  Using still larger volumes of air,
the proportion of atmospheric Pb existing as vapor-
ized Pb alkyl was found to be 1.3% of the total
Pb in air.

After reviewing minor emissions such as evapora-
tion of gasoline and blow-by gases, the products
resulting from automotive internal combustion are
considered.  This heterogeneous mixture of gases
varies in composition with the type of engine used,
gasoline of Diesel, and also with the conditions
under which the engine is operated.  Toxic emis-
sions described in detail include carbon monoxide,
hydrocarbons, nitrogen oxides, aldehydes, sulfur
anhydride and Pb, the latter from the addition of
the antiknock agents TEL or TML in amounts ranging
from 0.4-0.6 ml/1 of gasoline.  Concerning the con-
tribution of Pb to air pollution, the author cites
some concentrations reported in the literature,
such as a range of 3.6-14 yg Pb/m3 for Los Angeles
(Rose, 1962), and 2.42-5.10 yg/m3 for Milan (D'Am-
brosio et al, 1958); Petrilli and Kanitz (1962)
found 8.83 yg/m3 in gasoline service stations and
up to 60 yg close to a motor vehicle within the
city.  He comments that atmospheric Pb concentra-
tions found by various authors are difficult to
compare because of the different sampling and
analytical methods used.  He then refers to experi-
ments that have shown that prolonged daily inges-
tion of 1-2 mg Pb results in a notable increase of
Pb in the blood and of urinary and fecal Pb ex-
cretion, without, however, causing clinical signs.
According to Kehoe, an individual who absorbs
^0.03 mg Pb daily through the intestine (which is
1/10 of the total amount ingested) and ^0.02 mg
from the air, will tolerate, with a sufficient mar-
gin of safety, another daily dose of 0.03 mg,
which implies that the daily amount of Pb absorbed
from the air could be safely doubled as long as
the ingested amount remains the same.  Although
investigations made in 1947-1960 by the Swiss Fed-
eral Committee on Gasoline Additives are also gen-
erally optimistic, further studies concerning pro-
longed exposure to minimal doses of Pb should not
 be  neglected.   In  general,  the  author  recommends
 the adoption of  exhaust  control devices  for motor
 vehicles.
  He finally comments  on regulations recently
 adopted  in  the  State of  California  and in  France,
 by  saying that  the California regulations  appear
 to  be stricter,  prescribing  fixed standards of
 pollutants, but  to date  they do not seem to be  en-
 forced.  The French ones are broader,  in conform-
 ity with the general European trend in the matter,
 aiming to a mere control of  discharges.  (30 ref-

 The mean 210pb concentration in Antarctic  air at
 ground level at  the Base Roi Baudouin  for  the year
 1958 was found  to  be 1.3 x  10"3 decay/min/kg air.
 In  samples  of surface  snow  accumulated for 2-5  yr,
            910
 the average     Pb  activity was  of the  order of  100
 decay/hr/kg of  snow.   This  activity seemed to be
 independent of  the local rate of accumulation.  The
 variations of 210pD activity as a function of
 depth, studied  on  two vertical  flrn profiles span-
 ning an interval of >200 yr  at  two  bases showed
 the 210pb activity to  decrease  exponentially with
 depth.  The most plausible  interpretation  is that
 the rate of water  accumulation  and  the initial
 210pb concentration in the snow have remained con-
 stant at both places over the last  100 yr.

 Three American oceanographers and geologists have
 studied the fate of TEL  in nature after  its use
 as  automotive antiknock  agent.   Since  Pb is not
 combustible, Pb  particles escape into  the  atmos-
 phere from where they are washed out by  rain and
 carried into the water of rivers and eventually to
 the oceans.  In  the Pacific  and Atlantic ocean and
 in  the Mediterranean, considerable  Pb  deposits
 have been found  at  depths of <900 m, while at lower
 depths the Pb concentration  rapidly decreases.  The
 American investigators estimate that extraction of
 Pb  from plumbiferous rocks may  contribute  to these
 deposits at most 10,000  tons/yr, that  the  rivers
 carry ^200,000 tons of Pb compounds, and rain
 dumps ^275,000 tons directly into the  oceans.
 These figures will  soon  be ascertained by  a com-
 parative study of  the Pb content of snow in the
mountains of California  and  fossil  snow  from moun-
 tains in Greenland.
  According to H.V. Warren (1963) , vegetables grow-
 ing  near highways  in the US  contain 50 times as
much Pb as is permissible for human consumption.
 In  Derbyshire in England, a  disease called "Derby
 stomach" exists which is characterized by  colics
 and which is caused by prolonged ingestion of Pb.
There is also a  "Derby goiter"  due  to  Fe deficiency
 in  the soil.  Phenomena  of this kind have  induced
Warren to some general considerations.  He main-
 tains that man originally settled in the alluvial
plains such as the valleys of the Nile and Yang-
 tse, where the soil was propitious for human life.

excesses have developed.   It is perhaps still too
early to draw conclusions concerning health with
respect to human geography.   It could be possible
that the disturbance of a dietetic balance between
Cu, Zn, Hg, As, Se, V, etc,  has an influence on the
e'tiology of diseases like cancer and cardiac af-
flictions.  Pb could be responsible for multiple
sclerosis, that is,progressive degeneration of the
nervous system, thus leading to serious damage or
premature death.  Statistics seem to indicate that
multiple sclerosis is relatively frequent in re-"
gions where the soil is rich in Pb compared to
areas  where the Pb content is average or below
average.

Measurements of naturally occurring radioactivity
associated with air particulates in Cincinnati,
Ohio, are reported.  Measurements were made daily
for extended periods and, at the same time, mete-
orological variables such as wind speed and pre-
cipitation were observed so that their influence
on radionuclide levels could be evaluated.  Sam-
ples were taken at a height above the ground at
which air would be inhaled.   222^ an(j 220^
daughters were collected by drawing air through a
membrane filter from which their activity was
counted.   Seasonal and daily variations were stud-
ied.  A gross annual 222^ value of 260 pCi/m3 was
estimated  for Cincinnati from the average 8 AM and
3 PM concentrations.  210Pb and beryllium (7fie),
together with fission products from fallout, were
measured in particulates collected on glass-fiber
filters during April and May, 1961.  2l°Pb was
                separated chemically from the filter and its col-
                lected air particulates; the basic solution con-
                taining the Pb was acidified, precipitated as Pb
                sulfide and metathesized to the sulfate by heating
                with sulfuric acid in the presence of Bi holdback

                        AND AIR QUALITY STANDARDS.  Archives of
                        Environmental Health 8:39-43 (Jan.), 1964.
                The value of the concept of the body burden in set-
                ting air quality standards is discussed.  Body
                burden of a pollutant is defined as such level of
                the substance in organs or fluids of the body as
                either produces or is capable of producing damage
                or significant interference of the body or of the
                respective organ or tissue.  Estimation of the
                body burden in relationship to exposure depends on
                the development of sensitive and valid methods for
                measuring the levels of substances in biological
                materials, choice of populations of persons, and
                their availability for study, and the manner in
                which the biologic system is sampled.  A formula
                found uceful for exposure to carbon monoxide,
                for which the body burden concept has been used
                for setting the air quality standard, is shown.
                However, dynamic models should be developed and
                more widely used for  greatest use of body burden
                estimates.
                  Work is under way to set air quality standards
                for Pb.  From field studies so far undertaken, an
                estimate of the body burden of Pb has been obtained
                from the collection of blood samples.  These indi-
                cate a substantial difference between urban and
                rural residents, somewhat higher values in males
                than in females and a tendency of slightly greater
                values in smokers than in nonsmokers.  The latter
                difference is thought to be due to Pb arsenate
                sprays which were formerly used in tobacco cultiva-
                tion.
                  It is concluded that the body burden is valuable
                because of its relevance to exposures not only to
                elementary, but also to complex substances, and to
                the association of several trace metals.

 sponse to  8-hr/day  5 days/wk exposures,  data are
 insufficient for  the effects of  continuous expo-

 studies will be pursued with vigor,  it  becomes
 very important that  local  agencies  collect data on
 existing Pb levels.   Since Pb  exposures  are  from
 multiple sources, community  air  pollution stan-
 dards should be based on a portion  of the total
 limit for  population exposure.

         CATTLE AND HORSES  IN THE VICINITY OF A
         SMELTER.  Annals of  the New York Academy
         of  Sciences  111, Art.  2:595-611  (Apr.  24),
         1964.
 An outbreak of Pb poisoning  in 1962 in horses  and
 cattle from 3 different  farms  in the  vicinity  of a
 Pb smelter  near St.  Paul, Minn., where old battery
 plates were melted down, is  reported.  After 4
 cows  had died at  Farm A, the veterinarian serving
 the  area requested assistance.  Pb poisoning was
 confirmed on the  basis  of characteristic  clinical
 signs  exhibited by one  of  the  surviving  cows and
 the  presence of ^18  ppm  Pb in  the liver  of a dead
 cow.   In total, 9 cows,  2 horses and  6 ponies  died
 and  3  additional horses  showed signs  of  illness
 while  4  cows  from Farm C never exhibited  signs of
 poisoning.   The Pb concentration in the  blood  of
 12 cows  which had survived the episode,  ranged
 from  0.30-1.26 mg/1,  compared  to an average  normal
 of 0.10-0.129.  The  range of Pb concentrations in
 the blood of  6 horses tested in the vicinity of
 the  smelter was 0.23-0.47 mg/1 compared  to a normal
 of 0.04.  The Pb content of alfalfa-clover hay and
 corn silage  grown immediately across  the  road  from
 the smelter and fed  to the animals,  was  26-284 ppm
 (analyzed without further drying).   In order to  get
 a better picture of  the  extent of contamination,
 samples  of wintered-over vegetation were  analyzed.
 Contamination with Pb decreased with  the  distance
 from the smelter and was appreciably  greater when
 the samples were taken close to busy  highways.   It
was estimated that the minimum cumulative  fatal
 dose of Pb  for cows was 6-7 mg/kg/day while horses
 appeared to be more susceptible,  calculating  that
 they had ingested 2.4 mg Pb/kg/day.   Even under
 conditions  of prolonged intake  the  syndrome in
cattle was  acute or peracute.  Analysis of the Pb
 content of  the milk from 8  normal cows (0.006-
 0.013 ppm)  and from the affected showed a rather
constant relationship between Pb excretion in milk
and Pb concentration in the blood cells,   the  ratio
of Pb in blood to Pb in milk being  ^23.   The  high
 level of Pb  in the colostrum of a  Pb-exposed cow
about to freshen suggested  that the  blood-milk
barrier acquires  different  permeability charac-
 teristics for metals at the time of  parturition.
Also, Pb excretion in milk  was  not  enhanced during
 therapy with EDTA.  The conclusion was drawn  that
 the mammary gland and the kidney apparently behave
differently with regard to  excretion of the Pb
EDTA complex.
  Evidence  was presented that excessive mobiliza-
tion of Pb  by means  of EDTA,  at least  under condi-
tions of long-term accumulation in  cattle, is a
hazardous procedure.   The authors point out that
although  this observation was made  only  on  1  ani-
mal,  it is of sufficient importance to warrant
study.  No adverse reactions were seen in chroni-
cally poisoned horses, given 110 mg EDTA/kg iv on
3 successive days.  There was no effect whatever
on the Pb concentration in blood, leading to  specu-
lation on the mobility of Pb deposited in the
erythrocytes and in soft tissue generally under
conditions of chronic intake as compared to the
acute.
  Since public reaction to the Pb poisonings  on
the farms was vigorous, the state health department
was requested to analyze well water, home-grown
vegetables, and milk, and to test blood and urine
of residents.  In no cases was any  evidence of ab-
normal Pb accumulation found.  The  problem was
clearly one of hazard to herbivorous animals  in
the vicinity of the plant.

The study was undertaken for the purpose of corre-
lating atmospheric pollution and mortality from
cancer in German cities.  Dust from city streets
in Hamburg was collected over 19 mo and the weight
of dust, ash, benzopyrenes and trace elements was
determined.  The dust content of 19 samples taken
between September, 1961 and April,  1963, ranged
from 0.16-0.36 (av 0.233) mg/m3; for the year 1962
alone, the mean concentration was 0.217 mg/m-^.  The
proportion of the dust which was soluble in metha-
nol was 45% or 0.106 mg/m^.  On the average,  1000
m-' air contained 100 yg 3,4- and 76 yg 1,2-benzo-
pyrenes.  However, there were great differences
in 3,4-benzopyrene levels between summer and win-
ter.   A maximum of 388 Pg/m3 was reached in Janu-
ary,  1963, compared with only 17 ug in the previous
spring and summer, although the motor vehicle
traffic had not Increased.   The average concentra-
tion of trace elements during 1962 was found as
follows, in mg/1000 m^:   Pb, 2; Zn  and Cu, 1 each;
Ti, 0.5; Mn,  0.2; V, Ni, Cr, Sb and Co, 0.1-0.01;
Mo and Be, <0.01.  The high Pb content was attri-
buted to the fact that the sample was taken close
to a  traffic  light.  Seasonal and local differences
in the concentration of  the trace elements are
pointed out and compared with findings by other
authors.  The relationship of cancer of the lung
and other organs, and of respiratory diseases to
atmospheric contaminants, as reported for the US
and other countries, is  discussed.

                A cooperative,  1-mo study of ambient air quality
                was conducted in Duquesne, Pennsylvania, from Sep-
                tember 23 to October 30, 1963, to define the exist-
                ing and potential community air pollution problems.
                "Samples were collected continuously with automatic
                sampling equipment, and 30-min, short-term samples
                were collected periodically, using manual sampling
                techniques.  Total atmospheric particulate pollu-
                tants were estimated, and, additionally, particu-
                late samples were analyzed spectrographically for
                content of metals  (a total of 15, including Pb).
                Other pollutants determined were the various ox-
                ides, oxidants and aldehydes.  Particulate concen-
                trations during the study ranged from 99-963 yg/m3.
                  In correlating the percent composition of the met-
                als and  total atmospheric particulate concentrations,
                that of  Sb,  Cd, and Mn tended to increase with in-
                creasing particulate concentration while that of  the
                other metals did not generally so increase signifi-
                cantly.  The percentages of Pb for the various
                ranges of particulate concentrations varied from  0.1-
                0.6.  The atmospheric concentrations of  the metals
                were also compared to the national urban average.
                The metals content in Duquesne was higher than this
                average, particularly for Mn, Fe, and Cr.  That of
                Pb was 1.7 yg vs the national average of 0.5 yg/m3.

        (Fee.;, 1964.
The prospect for the establishment of a standard
for the satisfactory quality of the ambient air
in respect to Pb is discussed on the basis of
threshold ladies established for workmen and  on the
basis of observations in the laboratory over more
than 20 yr.   A hygienic standard of the quantity
of Pb in air to which workmen may be exposed with
reasonable safety has long existed and the value
set has been subject to much re-examination and
just recent  revision.  Despite any technical re-
finements in revisions of the standard,  it is still
a rough specification through the fulfillment of
which a serious industrial hazard is reduced by
purely technical means to reasonably acceptable
dimensions.   While, despite its shortcomings, it
has proved applicable as good operating practice
in the Pb industries, it is not adequate for  it
fails to portray fully the occupational exposure
of workmen to Pb.
  There is no evidence at present  that the Pb con-
centration in the general atmosphere in the US is
a source of hazard to any person or segment of pop-
ulation in this country.  While there  are cases
of Pb poisoning in industry and in the general pop-
ulation, their sources differ widely in type and
magnitude from those causing contamination of the
ambient air, food and beverages of entire communi-
ties.  Although lack of evidence that the concen-
trations in air are hazardous is not, in itself,
convincing, there already is the required evidence
as to conditions, quantitative and reproducible,
that cause Pb poisoning, and as to the order of
magnitude of the present margin of public safety.
Extensive experience in industry and laboratory
experiments have shown that Pb poisoning occurs in
man only when certain well-defined conditions are
fulfilled.  These rest on a range of concentration
in blood (and a corresponding but less defined
range in urine) which denotes an unusual (or ab-
normal) absorption rate and extent as compared to
that common to the "normal" person or population
group.  Up to a certain point in concentration,
no known or presently demonstrable symptom or sign
of Pb intoxication may be expected to occur even
in the least tolerant (or most susceptible) person
of any age;
  Therefore, there is now an empirical standard
whereby the present population in the US or an in-
dividual member of it can be identified as "normal"
in terms of the range of the concentration of Pb
in the blood (and urine), which has been found to
be characteristic over a period of >20 yr of obser-
vations in the Kettering Laboratory.  A standard
which defines the limit of human safety with re-
spect to the absorption of Pb also exists.
  It is highly dubious that a standard for the Pb
content of ambient air would be adequate or even
relevant in the maintenance of public safety, so
long as the amount of Pb absorbed by the average
citizen from food and beverages is larger than that
absorbed from the air.  The control of atmospheric
Pb, therefore, cannot obviate a potential hazard
of Pb intoxication to the general population.  In
order to justify and enforce an air quality stan-
dard for Pb, there must be a reasonable certainty
that the alimentary absorption of Pb has been sta-
bilized.  Since Pb excretion in the feces repre-
sents 90-95% of the ingested Pb, a faithful por-
trayal can be had of the daily intake of Pb in
food and beverages.
  The standard of safety as to the Pb content of
air in industry, while crude, is reasonably valid,
for in occupational exposure, the Pb increment
associated with inhalation of Pb can become suffi-
ciently large to reduce the significance of the
dietary Pb.  However, the variable of intermittency
has to be considered since occupational exposure
occurs only for 8 hr daily, 5 days/wk while expos-
ure to ambient air is continuous, although some-
what variable in intensity.  Precise observations
in the laboratory are required to validate the es-
tablishment of a concentration to which populations
may be exposed safely.  Experiments are under way
to study the pattern of the metabolism of Pb upon
varying duration of exposure to a constant level
of atmospheric Pb.  After following the daily in-
take and output of Pb of 2 healthy subjects for
^1 yr, the subjects were exposed in 2 parallel
respiratory chambers to air containing 0.15 mg Pb
(as sesquioxide)/m3, in particles of 0.05 y in
diameter; for 4 mo they spent 3 hr daily there and
for corresponding and successive periods of time
6, 9 and 12 hr, respectively.  Six more months of

observation with no further exposure, will permit
determination of the mathematical relationships in-
volved in varying degrees of intermittency of an
otherwise constant type and degree of exposure.
  A question that still needs investigation is
what least change in concentration of Pb in ambient
air is capable of inducing a demonstrable change
in the output of Pb from the body.  This threshold
has been established experimentally as to inges-
tion of Pb, thus providing a basis for a standard
of safety with respect to dietary Pb.  Such a
threshold for respiratory absorption, considered
together with the factor of time, will designate
a level of Pb concentration in the air to which
healthy persons can be exposed over a lifetime
without accumulating a potentially dangerous body
burden of Pb.

        PLANTS WITH LEAD FROM MOTOR EXHAUSTS.)
        Naturwiasenschaften 51,  No. 15:367-8,  1964.
In introducing their discussion,  the authors con-
sider that the constantly increasing contamina-
tion of the atmosphere and vegetation by Pb is
almost exclusively caused by automotive exhausts.
According to a German regulation, automotive fuels
must not contain >0.06 vol% of TEL, and a content
of not >0.05 vol% is recommended.  The contamina-
tion of grass with Pb in concentrations up to
300 yg/g of dry substance along traffic-bearing
roads in the USA, as reported by  Cannon and
Bowles (1962), is cited and remarked upon that
cattle ingesting such grass would not only exhibit
Pb poisoning but that considerable Pb would appear
in the milk, rendering rearing of offspring im-
possible in some cases.
   In the summer of 1963 the authors investigated
the relationship of traffic density to the Pb con-
tent of plants and soil at different locations in
West Berlin.  They found Pb in ug/g of dry sub-
stance (with percent that can be washed off given
in parentheses):  in garden in Frohnau and Botani-
cal Garden, both remote from traffic: in grass, 6.0
(<5) and 8.5 (<10), respectively; in roots, 43.0
and 46.5; in soil, 18.5 and 66.0.  At 300 m from
main road the corresponding values were:  15.3
(10); 56.2; 29.3.  On divider strip in a road
bearing 11,000 autos in 12 hr:  16.2 (30), 38.8,
and 6.4; the same in a road bearing 23,000 cars in
12 hr:  47.9 (20) 38.0, and 12.3; traffic island
of square bearing 32,000 autos in 12 hr:  57.0
(30), 65.2, and 36.5, respectively in grass, roots
and soil.  The high percentage of Pb which can be
washed off the grass points to a high adsorption at
the surface of the leaf so that total absorption
and transport in the plant would scarcely occur.
The Pb contained in the roots is  thought to have
been taken up from the soil.  According to the
authors' findings adsorption of Pb by the root in-
creases with the Pb content of the soil but the
root transports only small amounts of Pb to the
surface parts of the plant.  The high Pb content
of soil in the Botanical Garden is thought to be
due to frequent fertilization with leaves gathered
in the streets.

                the paper, the  importance of Pb as a pollutant is
                briefly discussed.  The toxicity of Pb has been
                proved in studies on occupational exposure.  Emis-
                sions from motor exhausts are the almost exclusive
                sources of Pb found in polluted air as most gaso-
                lines contain up to 3 ml Pb/gal.  According to
                Cholak and coworkers (1950, 1952), acute Pb toxici-
                ty with characteristic signs of chronic Pb poison-
                ing have not been observed as a result of exposure
                to Pb concentrations in air.  However, in view of
                the presence of Pb in the general environment (in
                food, beverages and household products), the author
                believes that the potential hazards of Pb in rela-
                tion to the total body burden needs to be assessed,
                by citing, in part the work by Hofreuter et al
                (1961) who analyzed Pb levels in blood and urine
                of urban and rural populations and who confirmed
                earlier studies on the body burden of Pb in rela-
                tion to residence.

                A 5-wk pilot study of ambient air quality was con-
                ducted in Baltimore, Maryland, in March and April,
                1964.  Typical  atmospheric particulate pollution
                in Baltimore and several other American cities of
                similar size as measured by the National Air Samp-
                ling Network were  tabulated.   Total  suspended  par-
                ticulates and  Pb  composition,  both  in  pg/m , were
                as  follows:  Baltimore, Md.,  144, 0.7;  San  Francis-

 as determined in  24-hr collections  every  2 wk on
 a random schedule in  the central business districts
 of cities  in the  US,  are tabulated  according to
 several parameters depicting air quality  (these
 include the arithmetic and geometric means, stan-
 dard  geometric deviations and concentrations ex-
 ceeded by  the highest 1% of samples and their mean
 ratio).  The following 6 cities recorded  highest
 concentrations for 2  metallic pollutants, as in-
 dicated:   Baltimore,  Sb, and Cr; Birmingham, Sn and
 Zn; Boston, Ni and V; Cleveland, Mn and Ti; Los
 Angeles, Cu and Pb; Tacoma, Si and  Cd.  Maximum
 pollutant  concentrations are also compared with
 the threshold limits  established by the American
 Conference of Governmental Industrial Hygienists.
 Gaseous pollutant parameters as found in  a Contin-
 uous  Air Monitoring Program are also given for
 S02 concentrations measured in 8 cities and for CO
 and N oxides for  some cities.  Gaseous pollutant
 concentrations on the worst 1% of days were less
 than  the ACG1H levels but greater than those estab-
 lished in  the USSR.   Pollutant concentration was
 found to be related to size of city and distance
 from  its center.  The sulfate particulate concen-
 tration was related to S02 concentration.
  In  discussing means for improving US air quality,
 combustion processes, including coal combustion
 and motor  exhausts, are held to be  the major
 sources of pollutants.  Means are presently avail-
 able  or are being developed to control the emission
 of all these pollutants except the  N oxides, which
 come  from  all combustion sources.   There is no
 known easy method for controlling N oxides.  In
 the decades ahead, the ultimate solution  to pollu-
 tion  from  the N oxides as well as the other  pollu-
 tants may  be the  use  of much less high temperature
 combustion, in homes, vehicles, and industry.
 Fuel  cells and atomic fission or fusion might then
 power the  nation  electrically.

Extensive measurements of atmospheric radioactivi-
ty have been made at various sites by using air
monitor equipment of the US  Naval Research Labora-
tory,  primarily designed  for the detection of
nuclear explosions.   The  technique used involved
the estimation of the contribution of 214pb plus
214jii, 212pt, plus 212Bi and  gross fission products
to the total 3 activity collected on air filters
through measurement of the rate of decay during a
16-hr  period.   The procedure permits the determina-
tion of the contribution  of  222Rn daughters (214pb
plus  214Bi) and 220Rn daughters (212pb plus 212Bi)
to the initial radioactivity.   The measured con-
centrations of 222Rn an(j  its daughters were repre-
sentative of the minimum  in  the diurnal variation
of this activity,  and those  measured of 212pb,
because of  its longer effective life-time on the
filter, were more characteristic of the daily aver-
ages of this isotope in the  air.   Measurements of
natural radioactivity in  ground-level air made
during 1950-1962 in Wales and  Kodiak,  Alaska, Wash-
ington, D.C.,  Yokosuka,  Japan,  Lima, Peru, Chacal-
 taya, Bolivia, Rio  de Janeiro,  Brazil, Little
 America V, Antarctica and  at  the  South Pole  ranged
 from 0.47-122 PCi/m3 for 214pb  and  from  <0.01-
 2.54 212pb.  The data show that sites located in
 the path of maritime air have generally  lower
 natural atmospheric radioactivity than those whose
 environmental air has had  an  overland route.  Dia-
 grams are included  of monthly and seasonal varia-
 tions and explanations of  these findings with re-
 spect to geographical location  are  attempted.
  In conclusion it  is stated  that the radioactivity
 of the air is the result of the interaction  of
 many factors, including time  of day, season, and
 weather.

210pb, which has a 22-yr half-life, is formed in
the atmosphere by the normal process of decay of
222Rn.  ihe removal process for 210pb is rainout,
with small quantities removed by dry deposition
or fallout.
  In the study reported, some of the observed con-
centrations of 210pb in the air were considered as
a function of time and space, and an attempt was
made to correlate these results with the concen-
trations of 222Rn observed concurrently at the
same sites.  The sampling sites were located pri-
marily along the 80th meridian (west) except for
the Mauna Loa,  Hawaii station which is at a high
altitude in the Southern Hemisphere.  'lOpb  con-
centrations in the air at ground level were deter-
mined monthly or bimonthly from September 1960
through 1962,  by radiochemical analysis, and the
data obtained in units of 10~^^ Ci/m^ air were tab-
ulated and presented in bar graphs as a function
of time and latitude.  At the subtropical and
tropical sites (Miami to Antofagasta), definite
changes according to periods were found which oc-
curred at roughly comparable times of the year
regardless of latitude or season, both at high-
altitude and sea-level sites.  Month-to-month
changes at the other stations in the Northern
Hemisphere were often large and erratic, with no
discernible seasonal pattern.  A decreasing con-
centration of activity was obvious in the more
southerly regions, due to the lack of appreciable
222Rn sources in that area.  The effect of lati-
tude on average 210pb concentrations in ground-
level air was studied for 2 successive 1-yr peri-
ods.  The profile obtained for 2lOpb was similar
to that of 90sr in the air, as measured at the

same sites.  The lowest concentrations of air-
borne radioactive isotopes were found at the South
Pole.  Measurements of the ratio of 21Opb-222Rn
were not suitable for the determination of the
time 210pb remained in the atmosphere.
  Some data on the concentration of 210pb in rain
water are included.  Islands and coastal sites
were found to exhibit lower 210pb concentrations
than inland sites or sites lying in the path of
continental air masses.  Thus, the 210pb activity
in rainwater at Samoa was 0.23 pCi/1 compared to
2.5 in Glenview, Illinois.

        Gelsenkirchen,  Germany):   Die Autoabgase
        und ihre Bedeutung fur die menschliche
        Gesundheit.   (AUTOMOBILE EXHAUSTS AND
        THEIR SIGNIFICANCE FOR HUMAN HEALTH.)
        Zeitschrift fUr PrHventivmedizin 9:148-59
        (May-June),  1964.
The significance for human health of automobile ex-
haust gases, such as CO, Pb compounds and carcino-
genic agents, is discussed and precautionary meas-
ures are suggested.  It has been estimated by
Hettche (1961) that 35% of air pollutants are at-
tributable to industry, 42% to domestic heating and
20% to automobile exhausts; in some large American
cities, automobile exhausts may contribute even
60-80%.
  CO is emitted practically solely by gasoline
motor vehicles.  The CO concentration at metropoli-
tan traffic centers in Germany av 15 ppm, though
in the industrial Ruhr area sporadically values of
200 ppm have been noted.  Pb as chloride and bro-
mide, of a particle size of 0.68-2.70 p, is emitted
in the automobile exhausts through the addition of
TEL as antiknock in the fuel.  In the environment
of the Institute for Hygiene in Gelsenkirchen, the
author found atmospheric Pb concentrations of 0.5-
3 yg/m3; Dubrowskaya's (1960) values from Russia
ranged around a few yg/m3, while American cities
with heavy automobile traffic report 30-40 with a
rush-hour peak of 120 yg/m3.  In Switzerland, at-
mospheric Pb levels are generally <5 yg/m^.   The
prohibition of adding Pb to fuels, in force until
1947, has been abolished because the amounts were
too small to constitute a health hazard.  The MAC
of Pb in work places in Germany is 150 ug/m^; this,
however does not apply to pollution of the general
atmosphere.  The blood of normal man contains 20-
30 yg Pb/100 ml.  The toxic threshold of 50-60 yg/
100 ml has not even been reached by individuals
particularly exposed to exhaust gases, but Hofreu-
ter observed that city people have a higher Pb
blood level (av 20 Ug/100 ml) than the rural popu-
lation  (av 14 yg/100 ml).  According to  the  au-
thor's observations, the average Pb concentration
in the blood of healthy subjects has been increas-
ing slightly during the last few years though re-
maining still far below the toxic threshold.  But
he questions whether, with increasing use of motor
vehicles, critical values may not be reached some
time.
  Among cancerogenic substances, emitted as  auto-
mobile exhausts, benzpyrenes and anthracenes pre-
sent the greatest hazards.  These polycyclic hydro-
carbons reached concentrations of 330 yg/1000 m3 in
Hamburg during winter and in Liege and Bologna
values of 360 and 200, respectively, were measured.
                These  levels are much lower during summer, decreas-
                ing for example in Bologna to 6 yg/1000 m3.  At
                the present time, a relation between automobile
                exhaust gases and lung carcinoma could not be
                proved experimentally although statistics  seem to
                indicate such a relationship.
                  The  author next considers the possibility of
                additive or synergistic action of the individual
                components of the exhausts, which may be even higher
                than the sum of the effects of the individual com-
                ponents.  Apprehensive of a situation in European
                cities such as had been reported for California,
                he advocates the installation of filter or after-
                burner equipment in motor vehicles.  He also sug-
                gests  exhausting the gases through the roof of the
                vehicles as some trucks already do, instead of
                having the exhaust pipe several inches above the
                ground, in the breathing level of children and in-
                fants.  Careless and faulty emission of exhaust
                gases  should be forbidden by law and a continuous
                monitoring of air pollutants should become manda-
                tory in all cities.

                This paper was given as part of a symposium on
                "occupational diseases" on May 30, 1963, at the
                University of TUbingen, Germany.  Various  toxic
                substances occurring in industry are discussed
                and the following is said concerning Pb:   Chronic
                Pb intoxication caused by the inhalation of Pb-
                containing dust has occurred frequently but due to
                sanitary measures this hazard has decreased.  How-
                ever,  a new hazard has developed by the increase
                of motorized traffic.  Pb alkyls  such as TEL are
                added  to motor fuel and after combustion exhausted
                as Pb  chloride or bromide or are deposited in the
                motor.  Chronic Pb poisoning may occur in  places
                where  automobile or plane motors are cleaned.
                The atmosphere in large garages is also harmful
                when inhaled over a prolonged period of time.
                Whether the amount of Pb in street dust has al-
                ready  reached a critical threshold, is a matter
                of argument.

                This report covers Pb aerosol sampling carried
                out during the winter of 1964 in several midwest-

                tion calculation used in the previous report
                (1963).  From all of the analyses of Pb aerosol
                size distributions, the conclusion was drawn that
                a single average size distribution can be  used to
                characterize atmospheric Pb aerosols, regardless
                of geographical location.  The mass median diame-
                ter is 0.25 y, upper and lower quartile points
                are 0.16 and 0.45 y, and relatively little of the
                total  mass is larger than 1 y.

The contamination  of the atmosphere, soil and veg-
etation at a location ^3 km from 2 Pb smelters was
studied.  Pb, Zn,  Cd and Al were determined po-
larographically on 1 polarogram.  The air was
passed through a 1-4% solution of nitric acid,
the nitric acid was then evaporated and the salts
were transformed into chlorides and polarographed
in a 2% solution of citric acid in an atmosphere
of pure N.
  Concentrations of Pb in the atmosphere ranged
from 2.5-200, and  of Zn, 8.U-700 yg/m3.  Dust
settled in containers on the ground had a Pb con-
tent from 0.42 to  2.827..  Soil at 200 m from the
source contained 495 mg Pb/g and 385 mg at 4000
m.  At 2-km distance, the Pb content in cherry
leaves and in grass was 7.66 and 0.628 mg/kg, re-
spectively.  Atmospheric pollution was reduced by
90% by passing the smelter fumes through a 100-m
tunnel, then through an 80-m high stack.
  The possibility  of absorbing excessive amounts
of Pb and the metabolism of Pb are briefly dis-
cussed.

        AIR POLLUTION STANDARDS.  Journal of the
        Air Pollution Control Association 14:5-15
        (Jan.), 1964.
The author discusses air quality standards (AQS),
specifications, and threshold limit values; pro-
cedures used in setting such standards in USSR and
in West Germany as compared with the US; applica-
tion of the zoning concept to these standards;
procedures used for setting emission specifica-
tions in West Germany, and American emission
standards; single-valued vs multi-valued emission
standards, and application of the zoning concept
to emission standards.  Included among the 19
tables is 1 showing New York State surface water
classification for the purpose of assigning stan-
dards of quality and purity.
  The conclusions  of this presentation are as fol-
lows:  The averaging time incorporated in an ambi-
ent AQS must be carefully chosen with relation to
the effects of excessive air pollution intended to
be prevented by the imposition of the standard.
The relationship between an emission standard and
the AQS for the pollutant emitted is complex.  For
administrative purposes, it is preferable that
both standards be  stated in as simple terms as
possible, even though this may result in a depar-
ture from the actual relationship between them.
Where an attempt is made to include this relation-
ship, the recommended combination is for the AQS
to be stated in simple form; the emission standard
to be in as complex format as necessary for valid-
ity.  The application of the zoning concept to
both ambient AQS and emission standards appears to
be fundamentally unsound.  Nevertheless, some ap-
plications of zoned ambient AQS may be justified
where buffer zones are employed; and some applica-
tions of zoned emission standards justified to the
extent that they allow those standards which are
feasible now to be imposed now.

D.D.  Smirnov's publication in 1962 (Abstract No.
3011) concerning a study of 263 children from
nurseries and kindergartens situated in the vicin-
ity of a fabricating plant for refined Pb is re-
viewed.  The report records incipient calcifica-
tion of long bones seen in X rays of 48 children,
together with urinary Pb of 0.01-0.028% in 27 of
them.  StBfen remarks that West German readers
will wonder why the urinary Pb was measured rather
than the urinary CP.  The same procedure was fol-
lowed by A.S. Zykova in her paper on pollution of
the atmosphere with Pb and its effect on the
health of the population.  (Gigiena i Sanitariya
No. 2:12, 1957, reviewed in Zentralblatt fdr Ar-
beitsmedizin und Arbeitsschutz 13:39-40 (Feb.),

the contaminated area, StOfen wonders whether
this is not derived totally or partially from the
atmospheric Pb dust instead of from the soil.  He
also regrets that the state of the children's
health was not described, nor were the climatic
conditions (duration of dry periods, summer tem-
peratures) considered for a country with such
vast differences in climate as the USSR.  In hot,
dry weather, Pb contained in the soil is inhaled
along with the dust.  Otherwise, the reviewer
commends Smirnov's report and recommends that a
similar study be made in West Germany.

Studies by the above Institute on the amount of Pb
which passes into various types of water in distri-
bution systems constructed of Pb and Pb alloys
showed that, with the exception of pipes carrying
dune water, there was little difference in the
amount of Pb dissolved from pure Pb and Pb-alloy
pipes.  Amount of Pb dissolved from Pb-alloy pipes
was much greater when dune water was transported.
In stagnant water most of the Pb was dissolved
during the 1st few hours.  Concentration of Pb in
old distribution systems was found to be less than
that in recently constructed water mains.  (From

Using the dithizone method, experiments were made
to determine the concentration of Pb in 4 differ-

Pb pipes  for 8 hr and after the water had been
                                                      flowing for some time.  After standing for 8 hr
                                                      the concentration of Pb varied from 0.06-0.496

        OF GROUND WATER SUPPLIES BY GASOLINE.)
        Gas- und Wasserfach 93, No. 8:205-9, 1952.
Ground water contamination by gasoline in the vi-
cinity of Munich, 1 case in 1939 (4000 1. with a
strikingly high degree of nitrite and only a trace
of nitrate) and 1 in 1940 (670,000 1. containing
TEL) from leaks in underground gasoline storage
tanks affected the drinking water drawn from wells
in nearby residential areas.  The first signs of
the contamination were gasoline-like taste and odor
of the water.  The water from the affected wells
was examined and the area of contamination found
to be less extensive than initially expected.  The
contaminated wells were closed for public usage and
the residential areas connected to the city water
supply lines pending examination of the cause of
the contamination and correction.
  The gasoline had penetrated the soil for a dis-
tance of ^2.5 km.  In chemical analysis, it was
surprising that the gasoline had mainly caused a
reduction in the nitrates, a reaction not achieved
under laboratory conditions but evidently easily
accomplished in the ground, giving rise to the
intermediary product, nitrite.  Formation of am-
monia did not ensue.  Pb content, examined by the
dithizone method, was not found in the 1st 2 yr
of the contamination period.  The highest value es-
tablished was 0.05 mg/1.  In February 1942, the
highest Pb value was 0.4 mg/1 but in 1943 no Pb was
found except in some isolated cases at the negligi-
ble level of 0.02-0.1 mg/1.
  Nitrate reappeared in considerable amounts after
2 yr, justifying the assumption that no significant

amount of gasoline was present in the soil.  In
1943, tests in case 1 showed the water to have re-
turned to normal.  Gasoline taste and odor had dis-
appeared as early as May 1941.  In case 2, where
the gasoline contamination had largely disappeared
by the summer of 1942, "hydraffrin" filters were
installed in those wells still affected by gasoline
taste and odor with  satisfactory results.  However,
in June 1944 in both cases, a slight gasoline odor
and reduction in nitrate content recurred in the
well water believed to be the result of the strong
precipitation occurring in June of that year which
activated the gasoline in those portions of the
soil not reached by the ground water.
  After the end of World War II, tests on the
basis of an isolated complaint concerning oily
spots in drinking water showed that the spots
were not the result of gasoline but most likely
the residue of fatty foods cooked or stored in
the containers which had not been entirely re-
moved by washing.  The ground water was found to
be normal.  Pb exposure or Pb intoxication was
out of the question in these 2 cases of consider-
able gasoline leakage, since the population was
supplied with normal drinking water during the
period of contamination and since the well waters
did not contain any significant amount of Pb.

Treatment of Pb pipe with a solution containing
30 ml Na silicate (40-42°Be)/l for 48 hr formed
a protective layer that prevented solution of Pb
when distilled water saturated with COj was
passed through the pipe.  Na phosphate gave no
protection.  Na2HP04 was partly effective, and a
mixture of Na silicate and Na2HPO^ was not as
effective as Na silicate alone.  (From Chemical

As determined in laboratory experiments, using Pb
nitrate in concentrations of  1, 10, and 50 mg/1,
the best absorbent for dissolved Pb in water was
found to be clay.  Pb solutions are completely
stable in neutral or acid solutions, but in alka-
line solution (pH 8.4) Pb content gradually precip-
itates on standing in contact with air.  For remov-
al from industrial liquors an alkaline solution in
combination with clay adsorbent is recommended.

Problems in the interconnection and unification of

scribed.  Pb, Cu, and cast Fe service pipes are
used.  Unprotected steel corrodes rapidly; water
fast removes Zn coating from galvanized Fe; plas-
tic pipe is promising for services <2 m, but re-
quires improvement before full use can be made.
Pb is believed to offer no health hazard; when
pipe is new, water standing overnight should be
discarded.  Laboratory tests are being carried out
to determine the actual amount of Pb dissolved
under such conditions.   (From Chemical Abstracts

Twenty-two different samples of plastic pipe ex-
truded from definite formulations of polyethylene
(PE) , polyvinylchloride (PVC) including saran,
rubber modified polystyrene, and cellulose  acetate
butyrate were  tested under the following condi-
tions:  Aggressive water  (Ann Arbor water,  consid-
ered to be as aggressive as any of the natural wa-
ters, was selected because of pH, high Cl,  high
natural F, hardness, high mineral, sulfate  and bi-
carbonate contents; pH was lowered to 5 to  make
it more aggressive in the extraction of heavy met-
als) ; effect of weathering; of burial in soil;
prolonged submersion in water; extraction  tests.
In the latter, cut specimens were immersed  in wa-
ter; special samples were prepared of a PE  electri-
cal  insulation compound and a PVC compound  contain-
ing Pb and Cd.  Enough color was extracted  from
the PE to turn the color of the water orange-brown.
From the PVC sample, 0.34 mg/1 Pb was extracted
at natural pH 9.6, and 1.25 mg/1 when the pH was
lowered to 5.  However, <6% as much Pb was  extract-
ed from the PVC pipe at pH 9.6 than from Pb pipe
under similar conditions.  Special samples  were
also prepared to contain varying quantities of Pb,
Cd and Ba much greater than was likely to be used
in making plastics.  Pb extracted from  1 sample
was 2.4 ppm, and from another sample containing
twice as much Pb, 3.90 ppm.  Similarly, 0.15 ppm
Cd was extracted from 1 sample containing Cd and
Ba, and 0.30 ppm from 1 containing twice as much
Cd.  No Ba was detected.  Other chemical constit-
uents of the water were not changed.  In addition
to these tests, taste and odor were examined and
effect on Cl residuals.  In animal feeding  tests,
rats received their drinking water from plastic
pipes.  The results showed that such exposure for
18 mo gave no evidence of any trouble insofar as
growth, food consumption, and autopsy findings were
concerned.  Separate experiments with rats  fed wa-
ter in contact with the special specimens of plas-
tic pipe containing Pb, Cd, and Ba, showed  no ex-
cessive amounts of Pb in the blood at the end of
the feeding period.  All pipes tested showed sus-
ceptibility to rodent attack.

An osteoporotic condition of young lambs which had
occurred regularly for many years in an old Pb min-
ing area in South Scotland is described.   The study
was carried out on the lamb crops of 3 yr, ie, 1953,
1954 and 1955 on 7 farms.   Although Pb content of
soil and pasture (19,500-17,800 ppm and 162-764 ppm,
respectively)', and blood (70.3 ug/100 ml),  liver
(58.2 ppm),  kidneys (77.0 ppm),  and bones (275-314
ppm) of many affected lambs was unusually high,
lambs with osteoporosis did not present a classical
pathological picture of chronic Pb poisoning.  In
lambs with higher Pb values there was basophilic
stippling of red cells and acidophilic inclusion
bodies were present in liver and kidney.  Unusual-
ly high values for Zn were found in blood and tis-
sue of affected lambs.  Possible involvement of
these elements and chelating metabolites such as
vitamin C in the etiology of the disease is dis-
cussed.   (59 references)

A mixture of Na pyro- and metaphosphates is often
added to a water supply to avoid scale formation in
the piping system.   Phosphates inhibit precipita-
tion of Ca carbonate and corrosion of metals.  How-
ever,  it was shown experimentally, using a piece of
Pb pipe 2.25 m long,  that by this procedure Pb con-
tent of water increased above the tolerated limit.

        (Jan.-Feb.),  1957.
In introducing his discussion, the author notes
that a common fallacy that fish will avoid an area
contaminated by industrial wastes, is not always
true;  eg, it had been found that fish appeared to
                 be lured to  gas-polluted water.   He  discusses  the
                 relationship between fish toxicity and  tempera-
                 ture,  dissolved oxygen, synergism and antagonism,
                 time and  toxicity, and alteration of washes  in
                 streams,  by  illustration with experimental work
                 of  the Academy of Natural Sciences of Philadel-
                 phia.  Among this, it was found  that concentra-
                 tions  of  TEL too low to cause death  immediately
                 will do  so with prolonged exposure;  that  death
                 occurred  when a fixed concentration  was reached
                 in the fish's body.  The concentration  in the  di-
                 lution water was important only with respect to
                 the time  interval required to produce a kill.

                The authors start the discussion by saying that
                although  the problem of waste water pollution with
                TEL is of primary importance, it has not been dealt
                with adequately.  Grushko, and Elizarova and Zamys-
                lova, who had studied this subject, gave contra-
                dictory results; the 1st, whose experiments  in-
                volved only 1 or 2 animals/concentration of  TEL,
                indicated a concentration of 0.001 mg/1 as elicit-
                ing barely perceptible or negligible pathologic
                changes, whereas E. and  Z. regarded 0.0002 mg/1 as
                the minimal active concentration.  Next discussed
                are methods for the purification of TEL-polluted
                effluents as developed by Lisitsin and Parshina and
                others, and an installation using Na sulfide treat-
                ment is diagrammatically illustrated.  A removal
                method had also been developed by Rodnevich  for

gas.  While sanitary regulations related to storage,
transportation and use of ethyl fluid prescribe the
construction of discharge outlets, there are no
sanitary requirements to cover the waste water from
those points on.  The regulations pertaining to
decontamination of soil are considered to be in-
adequate.  The author suggests that they be re-
vised or amended.
  The conclusion is that since the minimum active
TEL concentration in waste water is 0.0002 mg/1,
purification must be nearly complete and, in ac-
cordance with the present degree of sensitivity of
analytical methods, must be diluted to not less
than 1:1000 before the water is run into natural
water basins.  In the author's opinion, effective
purification is possible; also, a considerable
volume of the water can be reutilized at different
industrial stages without having been purified.
Secondary waste water from gasoline storage centers
can be successfully freed of TEL by the method of
Rodnevich.

Ninety analyses for Pb were made of water from 11
standpipes painted with red Pb.  The greatest
number of samples contained <0.005 mg/1.  A small
number contained 0.006-0.010 mg/1 and an approxi-
mately equal number 0.011-0.02 mg/1.  Two samples
contained between 0.02-0.05 mg/1.  Tests of the
extraction of Pb from panels coated with red Pb
oil paint indicated that no significant quantity
of Pb will be added to the average water supply by
the paint if the average daily consumption ap-
proaches the capacity of the tank.  If a phenolic
base paint with red Pb pigment is used, a substan-
tially lower rate of turnover will keep the Pb
concentration below significant levels.  Available
evidence indicates that only in extremely excep-
tional conditions, if at all could the Pb paint
produced a hazard to health.   (From author's

The effects of a number of variables on Pb solu-
bility were studied for oil-,  phenolic- and vinyl-
base paints.   The oil-base paint was found to be
at least 10 times more soluble under the conditions
of the test than either of the other two.   It is
noted that the oil-base paint  did not contain the
added litharge found in current specifications.

        Health Reports  74:501-10  (June),  1959.
The solubility of red Pb powder and of Pb from red
Pb paint of linseed oil, phenolic or vinyl base
was studied.  The solubility of purified red Pb
in distilled water was found by analysis to be
8.9 x 10~7 g M of Pb304/l (0.553 ppm) at room tem-
perature.,  The uptake of Pb by water standing in
contact with oil base red Pb paint varies with the
length of contact and the amount of Pb dissolved
by water varies inversely with the time of drying
of the paint film.  The leaching is a surface ef-
fect and the dissolution of Pb tends to reach a
constant value.  Na hexametaphosphate reduces the
rate of Pb solvency in distilled water within the
range of concentration used in treating public
water supplies while at >15 ppm, it increases its
solubility.  Na hydroxide up to 25 ppm depresses
the rate of Pb solution.

Waste waters from the collection and treatment of
ores contain Pb and other substances.  Mixing with
domestic sewage reduces the percentage content of
harmful substances and produces conditions for
biological decomposition without the use of a bio-
filter plant.  Chlorination is used for prelimi-
nary treatment, combined, for recovery of metals,
with electrolysis.  (From Chem. Zbl. 131:2991,

The leaching of Pb compounds from Pb-stabilized
polyvinyl chloride compositions in contact with
a constant volume of hard and soft water was in-
vestigated.  Six liters of water were stored at
room temperature in tanks 18xl2xl5-in. deep made
from the sample material by welding press-pol-
ished sheet.  After 18 mo contact, it was shown
that, with a compound stabilized with 3.77% basic
Pb phosphite and lubricated with 0.95% basic Pb
stearate, 0.5 ppm Pb was extracted by soft water
and no Pb by hard water, while a compound con-
taining only 3.81% dibasic Pb phosphite had none
of its Pb extracted by either hard or soft water.
Thus only some types of Pb compound are extracted
from these compositions by water.  It is concluded
that polyvinyl chloride compositions should not
be condemned as being toxic just because they
contain toxic substances, but should be considered
in light of the applications for which they are

In view of an expansion program of the Ethyl  Cor-
poration, permission was obtained for discharge of
residual process and sanitary wastes into the wa-
ter of the New York Slough near Pittsburg,  Calif.
tin estimate of the plant's effluent characteristics
was made and because of some concern as to  possible
or relative toxic characteristics, representative
samples of waste, simulating the proposed dis-
charge, were collected and used for preliminary
bio-assays with fish.  Relatively low levels  of
toxicity were determined, and it was found  that the
toxicity degree was significantly reduced when  sea-
water was used as the diluent.
  Along with background Pb concentrations in  the
receiving water as well as in the bottom sediments,
additional chemical and biological observations
were made.  Although occasional high spot values
were observed, most results  were well below or
within the recommended level of 0.05 mg/1 of  total
Pb.  The Pb concentrations of bottom sediments  var-
ied from as low as 2-3 mg/1 to 76, 129 and  250  mg/
1.  It appeared that the values obtained were fair-
ly representative of the concentrations and varia-
tions reported by earlier investigators of similar
soil and sediment samples.  The waste characteris-
tics were prescribed by the Regional Water Pollu-
tion Control Board of the San Francisco Bay and
water quality  criteria were specified, including
Pb, with  a maximum concentration of -0.5 mg/1,  1/2
mi from  the diffuser, and a median of =0.3 mg/1,
from 3 or more representative samples 100 ft down-
stream from the diffuser.  Pb in the bottom sedi-
ments 100 ft beyond  the geometric center of the
diffuser  as reported by the median of 5 samples
was limited to a maximum of 1 mg/1 greater than
the median of  5 similar samples taken in a control
area 1/2-3/4 mi from the diffuser.  Pb accumula-
tion or  increase in the median of 5 bottom samples
was limited to 0.1 mg/1 yr maximum.

The waste water, after passing through an oil
separator, is acidified and  passed for 1 hr
through a reduction column packed with Fe shavings,
where TEL is decomposed into ethane and Pb.  The
water is then neutralized with 10% Ca hydroxide,
settled for 2 hr, diluted with relatively clean
water, and discarded.  (From Chemical Abstracts

                 Pitting  of the  external surface of Pb water pipes
                 was  noted; in many cases  this was  accompanied by
                 surrounding  or  adjacent white deposits, sometimes
                 edged with black deposits.  The black deposits
                 were Pb  sulfide, and  the  white  deposits basic Pb
                 carbonate.   Such pitting  did  not occur when ground
                 waters carried  sufficient Ca  bicarbonate to form
                 a  protective coating.  The use  of  Pb  should be
                 avoided  in S-containing salts,  especially where
                 H  sulfide is being formed, and  also for potable
                 water supplies  of  low hardness.  The  danger of
                 differential aeration must also be considered.

The introduction of 2 characteristic factors,  the
lime dissolving capacity and the lime corrosivity,
is proposed  for describing the behavior of water
toward solid CaC03-  The lime corrosivity  can  be
considered as a function of Ca and CO-j actually
present in the water.  The Pb dissolving capacity
of a water can be estimated by means of the con-
centration of CO-j considered till now as an unes-
sential component of the bound C02-  The concen-
tration of 003 can be calculated by means  of the
HCO-j concentration, and the pH.  The quantities
of chemicals in the treatment of drinking  water
can be described in the form of equations.  The
activity coefficient can be described as simple
functions of the hardness of water.  A simple
method of determining the concentrations of C02
and C03 and  of the lime corrosivity by means of
nomograms is given.  (From Chemical Abstracts  61:

The rate of sedimentation of sludges can be accel-
erated by using organic flocculants.  These sub-
stances are used in very small quantities and are
to a large extent precipitated with the settling
sludge so that the effect on the oxygen demand of
the water is slight.  From a study of the  effects
of some 20 commercial coagulants on different
types of waste waters,  the author discusses the
most suitable pH values, the method of adding  the
coagulant, and the necessity with some waste wa-
ters of preliminary treatment before flocculation.
Analyses before and after treatment are given of
waste waters from galvanizing and pickling works
(including Pb), leather works,  textile works, and

        Washington, D.C., December 12-14,  1960:60-
        6, 1961.
This discussion concerns itself with 3 aspects of
the general subject of the Conference:  (1) pres-
ent chemical hazards to human health associated
with community water supplies, (2) similar hazards
which may be anticipated in the foreseeable future,
and (3) what is to be done to eliminate or control
these hazards.  In connection with the 1st, the
author mentions the bibliographic work of  the
Kettering Laboratory conducted in the early 50's
at the behest of the Ohio River Valley Water Sani-
tation Commission for biochemical and toxicologic
information on series of chemicals as potential
pollutants of water.  A series of some 28 reports
were  prepared  through  the  years.   These  made  evi-
dent  the  fact  that  toxicologic  investigations,  ex-
cept  in relation  to industrial  hygiene and  occupa-
tion  disease,  have  not extended into  the field  of
knowledge concerning the effects  of prolonged ab-
sorption  of  small quantities  of ingested chemicals.
In  fact,  only  2 contain information from which
sound and durable standards for human safety  and
well-being can be and  have been recommended,  ie,
F and Pb.  As  to  the future hazards,  the author
points to the  urgency  of developing methods of
recognizing  the increasing complexity of modern
technology with an  enormous growth of the problems
of  waste  disposal.   For the control of hazardous
pollution, physiologic, toxicologic and  epidemio-
logic research is advocated,  as well  as  the pres-
ervation,  so far  as possible, of  uncontaminated
water supplies and  the regulation of  drainage
areas and disposal  of  wastes  in streams  so  as to
limit contamination of water  sources  within speci-
fied  limits.   Information  for this can be obtained
only  by  the  combined and coordinated  efforts  of
government and other public and private  agencies,
including the  industrial.
  In  the  discussion Dr. Kehoe was asked  to  comment
on  the possibility  of  Pb content  in public water
supplies  which are  used for recreation wherein
motorboats using  Pb-gasoline  are  utilized.  The
answer was that the small  quantitity  of  Pb  escap-
ing from  the exhaust of motorboats is minute  com-
pared to  that  in  industrial wastes from  Pb  proces-
sing  plants  along the  streams.   Even  this is  not
of  great  importance because the Pb content  of wa-
ter is generally  not high  enough  to be a source of
danger except  where wastes are  dumped.   Under
these circumstances a  large portion of the Pb will
separate  out as a sediment; in  any event, it  is
not likely to  be  carried along  the stream in  suf-
ficiently high concentration.   As concerns  Pb con-
tamination from spillage of gasoline, the toxicity
of  gasoline  itself  would be of  more concern.

TEL in sewage, at concentrations of 0.01-1.5 mg/1
is decomposed in time into an inorganic form; a
resultant decrease in the toxicity of the sewage
was confirmed by experiments with algae.  For
safe discharge of sewage into reservoirs of water
currents or reuse, it is recommended that the
sewage be allowed to accumulate for 10 days, a
time sufficient for the decomposition of TEL.

discharged into the tailings pool.  Since the sew-
age contains 18-30 mg/1 phenols, phenol frothing
agents should be replaced with nonphenol agents.

                their effect on the sanitary regime of the water
                streams.  Sewage waters impart an unpleasant odor
                to  the water; there is a complete disappearance
                of  the odor with a dilution of 1:5000.  On heat-
                ing to 50°  the odor is intensified.  With a dilu-
                tion of 1:10 sewage waters give the water a metal-
                lic taste,  and with 1:50 the taste  is not discern-
                ible.  With chlorination of the sewage waters a
                chlorophenol odor appears, the intensity of which
                with a dilution of 1:1000  is No  1-2.  With a di-

with Pb was tested by placing the water in a Pb
pipe 4.5 m long and 1 in wide with a capacity of
1250 ml, and determining the amount of dissolved
Pb after 1-hr and 16-hr contact.  The water dis-
solved 25 mg/1 of Pb after 1 hr, and 115 mg/1 af-
ter 16 hr.  The same water, adjusted to pH 9.0-
9.5, dissolved 60 mg/1 of Pb after 1 hr, and 200
mg/1 after 16 hr.  Removal of C02 did not elimi-
nate the problem.  The corrosive action of such
waters is caused partly by free (X>2 but mostly by

(This is an abstract from "Method of disposing of
sludge from leaded gasoline storage tanks," pre-
sented by the author to  the API Division of Refin-
ing, Philadelphia, May 1963.)  Sludge from Pb
gasoline storage tanks is normally disposed of by
burial.  Various other methods of disposal ie,
roasting, chemical treatment, leaching, etc, have
been studied and found to be only partially ef-
fective.  Thermal treatment and weathering are the
most effective substitutes.  Heating sludge con-
taining 0.012% TEL for 20 min at 200°C reduces the
TEL content to 0.00001-0.00002% by weight.  Spread-
ing sludge in a 3-in layer on a ground or concrete
surface and leaving it for 4 wk at temperatures
>0° will reduce the TEL content to <0.002% by
weight (20 ppm).  It can then be treated as any
non-hazardous waste. The limit of 20 ppm organic Pb
was set by the Ethyl Corporation as being safe in
the open air after the sludge has weathered.  The
disposal procedure developed, so that a uniform
method would be followed, includes protection of
personnel.   In handling and spreading the sludge,
special clothing as recommended for tank cleaning
should be worn; masks will be required when there
is no air movement and vapor can be detected by
odor at face level.

A preliminary study was made of the pollution con-
tributed by outboard motors by operating motors
(a 5.4-hp 1939-49 and a 10-hp 1960 model)  in small
tanks of water.  The fuel mixture consisted of
regular Pb motor gasoline and an outboard motor
lubricating oil.  Fish toxicity tests and tainting
of fish flesh were included in the study.   Based
on the results of this study, an estimate was made
of the total quantity of fuel constituents con-
tributed to water by such exhausts in the US in
1959: 3-13 million gal gasoline, 7-15 million gal
oil, and 0.2-0.7 million Ib Pb.   The average con-
centration of pollutants in receiving water at
assumed extreme-critical situation, as tabulated,
is shown, in mg/1: nonvolatile oil, 1.7; volatile
oil, 0.94; Pb, 0.0087; phenols,  O.ul;  chemical
oxygen demand, 7.1.  The recommended quantity of
water dilution/gal fuel consumed for the protec-
tion of aquatic life is estimated as 10 times the
quantity that produces fish mortality, or ^19,000
gal.  A dilution of 16,000 gal water/gal fuel con-
sumed may have a significant toxic effect  on fish
life.  The authors conclude that the quantity of
water diluting the exhausts is of major signifi-
cance.   Unusually low water volume per unit of
fuel consumed will result in severe pollution from
outboard motor operation alone.

Five samples of ground water from Devon, Cornwall,
and Palestine were analyzed for Ra, Rn, RaD
(210pb), the total content of saline constituents,
and K.   The Rn content of the water (2.7-15 nCi/1)
was sufficiently high to require its removal.
210pb content was l-<6 yyCi.  Since the planned
treatment by aeration was unlikely to reduce the
Rn content of the water sufficiently from its
natural figure of 15 uCi/1, experiments were
carried out using a sintered glass disk from which
air was made to rise through the water in small
bubbles.  Partial removal (^75% after 4 hr) was
obtained with an air/water ratio of 2/1.  If cir-
cumstances permit storage of the water for a suf-
ficient length of time for radioactive decay, de-
pending on the Rn content and the half life of
3.8 days, treatment by aeration would be unneces-
sary.  If the air were frequently to stagnate

population in the area considered would be likely
to be exposed to a long-term hazard>.  For any very
large-scale aeration treatment, the plant should,
therefore, be situated in an isolated position.

An outbreak of  28 cases of Pb poisoning in dogs
and cats at Broken Hill Mine Township, Northern
Rhodesia,  is described.   Abdominal signs included
restlessness, pains,  vomiting,  diarrhea;  nervous
signs consisted of symptoms of anxiety,  hyper-
excitability, fear,  hysteria, continuous barking
and convulsions.   The onset of symptoms was usu-
ally very sudden; in cats only nervous signs were
observed.   Blood slides showed no basophillc stip-
pling.   The minerals mined at Broken Hill are  Pb
and Zn; it was suspected that the animals were in-
gesting Pb.  Treatment with CaEDTA (1  g daily  for
7 days for a dog weighing 30 Ib) was very success-
ful.   Pb determinations in tissues from dogs and
cats that had died of suspected Pb poisoning gave
the following results, Pb in ppm:  blood,  1.3-1.5;
kidney, 2.5-3.7;  bone, 5.5-42;  liver,  2.5-9.2;
stomach contents, 1.5-2.1.  Since there was a  pos-
sibility that the Pb hazard may involve also hu-
man beings, Pb  assays were made of the soil and
the vegetation in the area.  The Pb content of
soil from the yard of a house at the surface,  and
3, 6 and 12 in deep,  respectively, was,  g/kg soil,
2.^,  3.0,  1.6,  2.8.   Four samples of smelter ash
from drives in the housing area contained, in
g/kg, 0.20, 42.6, 0.10, 0.20, respectively.  Other
assays taken at different locations gave the fol-
lowing data, in g/kg:  soil,  traces to 5.9; un-
washed grass, 0.09-0.672; grass ash, 0.04-6.65;
water, mg/1, 0.1-25.4.

        475-L,  Article 86.-C105-6,  1963.
The element content was studied in the tissues of
2 American elm trees, one growing in normal soil,
the other in a location where its base was flooded
by galena and sphalerite tailings from an ore  mill
in Wisconsin.  Elements determined included Ca,
K, P, Cu,  Pb and Zn.   The Pb content of tailing
fines and of soil near normal trees was 0.02 and
0.015% of dry weight, respectively.   The differ-
ences in the Pb (and Cu) content of the ash had
no clear-cut relation to the increased amounts
                 found  in  soil.  As the higher amounts of Zn and P
                 in  soil resulted  in an increase of  these elements
                 only in wood  formed subsequently, chemical analy-
                 sis of tree rings may be a useful method of deter-
                 mining the year when the trees were exposed to
                 increased amounts in soil; also, in geochemical
                 exploration,  for  determining if a chemical anom-

                 made contamination, by determining  the date of
                 this increase, it may be possible to determine the
                 cause.

                 Fe; F; Pb; Cu; Zn.  Of the chemical substances, Fe
                 ranged from traces to 150 ml/1; F was found only
                 in  the discharge  from the beneficiation works
                 (0.96  and 1.1 mg/1); Pb ranged from 0-9.7; Cu,
                 from 0.03-8.22; Zn, from 0.08-400.2.  The concen-
                 trations of the above ions and several flotation

                 that since in the discharge waters  of the nonfer-
                 rous industry >20 different elements were found,
                 for 14 of which maximum allowable concentrations

                 of  heavy metal ions from industrial waste waters
                 by  precipitation  with K4Fe(CN)g, trapping the

                 the rate  of extraction.  Surface-active substances

 Experiments  on  the  kinetics  of  biochemical oxida-
 tion of  settled domestic  sewage have  shown that
 the  presence of toxic  metal  ions including Pb  not
 only causes  an  initial lag period until the micro-
 organisms  become adapted, but also causes  a marked
 reduction  in the total BOD,  and under these con-
 ditions, therefore,  the amount  of C>2  absorbed  in
 a given  period  indicates  the metabolic activity
 of the microorganisms  rather than the amount of
 oxidizable matter present.   In  the absence of  tox-
 ic matter, however,  the rate of biochemical oxida-
 tion appears to be  controlled by the  dissolved 02
 concentration and the  residual  BOD, and the pro-
 cess then  conforms  closely to a 2nd order  reaction
 until the  secondary  effect of nitrification be-
 comes significant.   (From Water Pollution  Ab-

        Aberystwyth):  FISH AND  RIVER POLLUTION.
        London,  Butterworths, 1964, 200 pp.
 Chapter 5  (pp 53-65; 29 references) deals with the
 coagulation  film anoxia theory regarding Pb, Zn,
 and  Cu.  After reviewing the literature in  relation
 to pollution of  rivers by Pb, Zn, and other heavy
 metals through  industrial and mining  wastes and in
 relation to  toxicity experiments on fish,  the au-
 thor discusses more  recent research on the  toxicity
 of Pb, Zn,  and Cu to fish:   (1)   toxicity of a solu-
 tion as influenced by  the degree of hardness of
 water; (2)  reexamination of  the  coagulation film
 anoxia theory;  (3) toxicity of  solutions containing
 both Cu and Zn.
   In experiments on  rainbow  trout with Pb nitrate,
•it was found that with water of  14 ppm hardness
 (as CaC03), all  the Pb added remained in solution;
 some precipitation occurred with water of 27 ppm
 hardness while in that of 53 ppm hardness most of
 the Pb was precipitated with not >1.6 ppm remain-
 ing  in solution.  The  precipitated Pb appeared to
 be nontoxic.   Solutions made up with  soft water
 Were toxic to the rainbow trout down  to a concen-
 tration of  <1 ppm.   It is possible that the exact
 nature of  the toxic  action of heavy metal ions on
 fish may depend on the nature and quantity of
 their gill  secretions,  the heavier the gill secre-
 tions the more protection.  Experiments with fish
 in this respect are revie-wed, with evidence sug-
 gesting that the toxic action of the heavy metal
 salts (including Pb) produces damage  to the gill
 tissues,  the formation of  a film of coagulated
mucus, or both, bringing about death by asphyxia-
 tion.  Of  the 3 metals, Cu is the most toxic to
 trout; the lethal limits of Pb and Zn are very
 similar for water of the same degree  of hardness.
 Synergism  and antagonism are included in the dis-
cussion.  The combination of Cu and Zn  is syner-
gistic; Pb, however, reduces the toxicity of Cu,
ie, it is antagonistic.
  Chapter 6 (The Metals as Salts, pp 68-82; 31
references) also deals in part with the reactions
of fish to Pb, Zn, and Cu.  Salts of Pb, Zn, Cu,
hydrolyze to some extent, but there is  little evi-
dence to suggest that the acidity of the solutions
resulting from this hydrolysis is sufficiently
high to be a lethal factor except, perhaps, at
very high concentrations.  The lethal limits of
the metal salts (including Pb chloride and nitrate)
are shown in a table.  The capacity of fish to de-
tect and avoid toxic concentrations of metallic
salts, including Pb, varies very much with differ-
ent species.  Experiments with 4 heavy metals
showed the ability of the stickleback to detect
and avoid them in the order of Pb, Hg, Zn, and Cu.

        TOXICITY DUE TO METALS IN INDUSTRIAL EF-
        FLUENTS, SEWAGE AND RIVER WATER.  Interna-
        tional Journal of Air and Water Pollution
        8:243-9 (Mar.-Apr.), 1964.
Although the toxicity of metals, at certain con-
centrations, to bacteriologic treatment processes
of wastes is well known, there is no  simple  test
for the quantitative measure of this toxicity.
Since pyridyl azo-resorcinol (PAR) gives a reddish-
brown color reaction with a number of metals (in-
cluding Pb), the author suggests that the PAR or
PAR minus iron (PAR-I) values be recognized as
such a measure.
  In the development of the method, the decision
to base the calibration on Fe was made because Fe
is not regarded as a toxic metal and is not subject
to very strict control.  The optimum pH for the
measurement of optical density was found to be 9
(using metanil yellow as reagent), and the wave-
length, 500 mp.  After construction of calibration
graphs based on Fe, optical density/concentration
graphs of other metals were then constructed and
their PAR factor determined.  This factor is that
which the actual concentration of the metal, ex-
pressed in pg/ml (or ppm), has to be multiplied
by to obtain the same results as would be obtained
using PAR and the Fe calibration curve.  The appli-
cation of this method is illustrated in the analy-
sis of a plating shop effluent before and after
treatment.

The discussion of the potential hazards of organic

ganisms reported by numerous investigators of many
compounds including TEL, for which the 96-hr median
tolerance limit,  that  is the concentration of ma-
terial at which 50% of bluegills can survive for
96 hr, was  found to be 0.20 mg/1.  The author con-

In-plant surveys were made of U mill processes to
determine the qualitative and quantitative nature
of the liquid and solid wastes.  Liquid wastes
contained 22&Ra and 210pb at concentrations poten-
tially hazardous to downstream water users.  Dis-
solved Th and U were usually not present in sig-
nificantly high concentrations.  Most of the ac-
tivity in the ore is made into solid waste, which
cannot  be safely discharged to surface waters.
Streams may be chemically polluted by compounds
leached from the ore or added in the processing.
The toxicity of mill wastes to aquatic organisms,
particularly the organic  raffinate from solvent
extraction was shown by visual observation of the
stream and bioassays.  Waste neutralization sig-
nificantly decreases dissolved 22^Ra, and treat-
ment with Ba compounds decreases it further.
Final disposal of liquid waste by evaporation and
seepage minimizes the amount discharged to sur-
face waters, and injection into underground  for-
mations was successfully  carried out.  Satisfac-
tory methods for the permanent retention of the
                highly active solids remain  to be developed.

The regulations prepared in 1950 came into opera-
tion on April 2, 1950.  They apply to the manu-
facture and decoration of pottery, the calcining,
crushing, grinding or sieving of flint or quartz,
the mixing of flint or quartz with other material
in the preparation of a pottery body, and the
manufacture of transfers, frits or glazes for use
with pottery.  The employment of women and young
children is prohibited in 11 groups of processes,
including some which involve the handling of Pb
compounds, and others where there is a silica-
dust hazard.  Other restrictions apply to loading,
carrying, and lifting by women or young persons.
Young persons may not work as wheel turners at
tile presses, or other work involving Pb or col-
ors.   Persons <16 yr are not to be employed on
certain scheduled processes when carried out in
factories other than leadless glaze factories, and
girls <16 may not work as lathe treaders.  All
persons employed on the scheduled processes con-
cerned with Pb and colors must be medically exam-
ined each month, and health registers are re-
quired.  The Appointed Doctor may suspend persons
from work on these processes.  For specified oper-
ations prescribed protective clothing must be pro-
vided, and must be worn.  Outdoor clothing must
be kept in accommodation to be provided outside
any room in which a scheduled or dusty process is
carried on.  Further regulations related to the
provision of washing facilities with hot and cold
water, soap, towels and nail brushes, the provi-
sion of mess-rooms, the washing of hands before
taking food, drink or tobacco, and the prohibition
of food and drink in workrooms where scheduled
processes are carried on.  Each workroom must be
ventilated without direct draughts on workers.
Drying stoves must generally be used for the dry-
ing of ware by means of heat.  The temperature of
any workroom must not be >75° F., unless the ex-
ternal temperature exceeds 65° F., and then it
may not exceed the external temperature by more
than 10° F.  In specified shops the temperature
must not be <55° F. after the first hr of work.
For a variety of processes efficient exhaust  .
draught is required, and the work must be done
under a suitable hood whenever possible.  Various
appliances for handling dry materials must be en-
closed and have exhaust draught.  Dust removed by
exhaust plants must not escape into a workroom,
and the air discharged from such plants must be
discharged into the open air.  There are also
provisions as to the construction, maintenance and
cleaning of floors and work-benches, the prepara-
tion and storage of clay dust, the control and
spacing of tile presses, the use of raw and Pb
compounds, glazing, color-blowing, hydrofluoric
acid, lithographic transfer making, and separation
of processes.  Among provisions as to the general
suppression of dust is a requirement that the
cleaning of potters' shops shall only be done by
adult males, and with vacuum-cleaning apparatus.
Respirators are to be provided for use where
specified.  (From Bulletin of Hygiene 25:474-5,

with machinery and plant used in raising and low-
ering loads in shipyards.  There are required
precautions against asphyxiation, injurious fumes,
or explosions, including provisions concerning
the ventilation of enclosed or confined spaces.
Other miscellaneous safety provisions deal with
fencing of machinery, air receivers, lighting,
work in boilers, etc,  hatch beams, and jumped-up
bolts.  Protective wear for the workers includes
adequate protection for the hands, goggles, hel-
mets or other shields for the protection of those
using cutting or welding apparatus, eye protection
for other processes and respirators for specified
tasks.  Miscellaneous health and welfare provi-
sions include the prohibition of the employment
of young persons on the handling of asbestos or

"^n employer owes an employee the duty of exer-
cising due care to provide  a reasonably  safe place
in which the  employee may perform his duties.
This is a common law duty,  not dependent upon the
Employers'  viability Act.   The duty is not dele-
gable and the fellow servant doctrine does not
apply.   Knowledge by the employee that certain
work is harmful to him is not good defense to a
complaint charging the employer with wanton injury
of an employee.  It is a good defense to a count
based on negligence,  but not to one based on wan-
tonness.  A painter used a spray gun in painting
truck trailers produced by his employer.  It was
alleged that  the employer wantonly injured the
employee by causing him to work in a room which
was not properly ventilated.
  For overruling the demurrer to the plea by the
employer of the claimant's knowledge of the dan-
ger, the judgment is reversed and the nonsuit set
aside and the cause restored for further proceed-

                The  essentials  of the modifications of  regulations
                adopted  in April 1945 are as follows:   (1)  Trans-
                port of  unstable TEL is prohibited. (2) Oils  and
                fuels  containing a maximum of 0.35 wt % TEL are
                subject  to the same conditions as ordinary oils
                and  fuels. (3)  Containers of TEL and its  mixtures
                and  those which  had contained these products  and
                were not disinfected must be labeled as to nature
                of product,  name, address and telephone number of
                sender.  (4)  Containers will  be considered as  con-
                taminated unless they have been completely neu-
                tralized and labeled "decontaminated."  (5)  The
                shipper  must deposit with his shipping  declaration
                a portable box with handle and a box of decontami-
                aant,  both labeled according to regulations.  The
                box  must contain 3 samples of the notice  approved
                by the minister,  showing  what to do in  case of
                accident and also 2 pairs of rubber gloves, 1 gas
                mask with a  case containing  400 cc active carbon,
                and  placards carrying the inscription "Danger, TEL
                fluid.   Do not  approach without mask."  (6)  Con-
                tainers  of these products must be loaded  into
                covered  cars.  (7)  No vehicle contaminated by  TEL
                is to  be put back into service unless it  has  been
                decontaminated under the  direction of a competent
                person;  the  wooden parts  must be removed, burned

 "A metal sorter in  a bearing works became incapac-
 itated  from  a uremic and hypertensive  cardiorenal
 ailment and  subsequently died.  His  attending
 physician was of  the opinion that a  contributing
 cause of the employee's death was Pb poisoning
 contracted as a result of the employee's work con-
 ditions.  A  nurse of the plant, an industrial hy-
 gienist, and a  physician, with 7 yr  experience in
 matters dealing with Pb poisoning, all contributed
 testimony and interpretations of the decedent's
 medical record  that tended  to substantiate the
 employer's contention that  the decedent  was  never
 unduly  exposed  to air containing Pb  in excess of
 the  nationally  recognized limits of  safety.   The
 court ruled  that  there was  substantial evidence to
 support the  conviction that Pb poisoning was not
 a contributory  cause of the employee's death."

These regulations require a medical examination
to be carried out within 4 wk of the commencement
of employment in all occupations listed in the
1st schedule.  This schedule also indicates the
periodicity of medical examinations.  Every medi-
cal examination is to include a general clinical
examination,  a blood examination and an examina-
tion of the urine.  The 2nd schedule prescribes
the manner in which the determination of the
number of stippled red blood cells/million red
cells must be carried out.  The medical practi-
tioner who carries out the examination must re-
port to the chief health officer the result of the
examination and certify whether or not the worker
is suffering from Pb poisoning of a degree render-
ing him unfit for work in any occupation involving
exposure to Pb.  A warning notice setting forth
the dangers of Pb poisoning, the measures of pre-
vention and the occupations, trades or processes
in which medical examinations are obligatory must
be posted in the workplaces.  The methods of treat-
ment of paint and of glaze for the purpose of de-
termining the percentage of Pb or compound of Pb
present are described in 2 other schedules.  (From

Until the time of this publication, examinations
of workers in hazardous occupations were performed
in part by the governmental industrial medical
officers or by duly authorized physicians or in-
dustrial physicians or by physicians appointed by
the unions.  The disadvantage of this was  that no
survey was available on the execution of the title
examinations, or failure to execute them;  there-
fore, it seemed necessary to the author to arrive
at a better recording and uniformity.  The exist-
ing regulations, etc, are segregated under (1) no-
tification regarding regulations providing medical
preplacement or follow-up examinations; (2)  guide
lines; (3)  notices; the various industries or
occupations, type and time of prescribed examina-
tions, other provisions, and basis of regulations,
are the column headings.  Pb-exposure is involved
in the following:  storage battery plants; decora-
tors and painters; Pb foundries; Pb paint and com-
pounds manufacture; glass manufacture; demolition
of ships; work with Pb-containing powders; potter-
ies.  Many of the regulations date back to the
earliest part of this century.

        RECOMMENDATIONS FOR LIMITS FOR LEAD IN
        FOOD.  London, H.ii. Stationery Office,
        1954, 11 pp.
The report sets out the various ways in which
food and drink may be contaminated with Pb.  It
also points out that Pb is stored in the body
and under certain conditions this immobilized Pb
may be released with toxic effects.  This cumula-
tive effect makes the control of Pb in foods of
particular importance.  Owing to practical con-
siderations it was not possible to set out maxi-
mal amounts to apply generally to all foods.  The
limits for different classes of foods and bever-
ages vary from 0.5-10 ppm, with 2 substances,
food colorings and solid pectin, having still
higher allowed limits.  The reasons for these
variations are discussed.  The details are set
out in the Report.  It is recommended that the
proposed limits should be made statutory but sub-
ject to periodical review.  It is also proposed
that the use of Pb piping for conveyance of beer,
cider or other beverages, the use of Pb-contain-
ing material for packing or wrapping food, and
the sale of domestic cooking equipment lined with
Pb containing tin or pottery glaze should be con-
trolled.  (From Bulletin of Hygiene 30:55, 1955)

                It is recommended that in preemployment examina-
                tions for work involving exposure to Pb persons
                showing the following conditions be excluded:
                emunctory lesions; liver and kidneys; arterial hy-
                pertension; blood disorders; lesions of the central
                or peripheral nervous systems.  In subsequent
                examinations, those should be excluded as being
                unfit because of presenting one or more of the
                above symptoms or those of Pb intoxication, ie,
                severe Pb colic or recurrences of it, persistent
                hyperazotemia or anemia, confirmed by the pres-
                ence of basophilic stippled erythrocytes.  Article
                12 prescribes the scope of hematologic examination.
                Furthermore, it is recommended that 3 successive
                examinations be performed in case of doubt and that
                a decision should not be based on one single re-
                dult.  It is also advised that the medical examiner
                keep abreast of the studies of Pb intoxication, be-
                cause of the importance of recognization of the
                degree of Pb intoxication.
                  The inability to work in a place where there is
                risk of Pb intoxication does not mean total inabil-
                ity for other work.

The Ministry of Labor and Public Safety approved
a revision of articles 10-14 with more detailed
articles 10-16.  These specify that workmen should
not be assigned to jobs in areas where Pb intoxi-
cation is possible without a medical approval, and
that he should not be continued in the same occu-
pation unless medical approval is obtained 1, then
3 mo after employment, and at least every 6 mo
thereafter.  The responsibilities of the manage-
ment of the plant are also determined in the arti-
cles.  The specifications for physical check-up
are minutely described.  These provide for stip-
pled cell and erythrocyte counts and hemoglobin
determinations at stated intervals.  The physician
for the industry has the right to perform complete
hematologic tests and tests for blood urea upon
his discretion.  If the management is convinced of
the efficacy of the preventive measures taken and
if no cases of Pb poisoning have been reported in
its plant, it may apply for exemption of the an-
nual hematologic examinations to the regional Fac-
tory Inspector.  An up-to-date register should be
kept either for the entire plant or parts of it,

Considering 1.5 mg Pb/day as the maximum amount
that may be ingested without harm and that a child
with severe pica may ingest the paint from 12 in2,
this film should contain not >1.5 mg Pb.  Since
indoor paint contains a minimum of 60% pigment or
7.2 Ib/gal, the amount of Pb necessary to deposit
1.5 mg/12 in2 is equivalent to 7.2 and 10.8 g/gal
(based on estimates of 400-600 ft2 coverage), or
Pb content of 0.22-0.3%.  Therefore, 0.3% is sug-
gested as the level below which decorative paints
for children's toys and furniture can safely be
labeled as nontoxic.

A concise review is given of the osseous, articu-
lar and musculo-tendinous affections which may
occur as the consequence of occupational accidents
or in the course of occupational diseases.  A dis-
tinction is made between occupational risks for
which in France compensation is obligatory (teta-
nus, brucellosis, carbon disulfide poisoning, Pb
poisoning, injury from roentgen rays or radioac-
tive isotopes, chromic acid poisoning, arsenical
poisoning, compressed air lesions, pneumoconiosis)
and those for which it is not (Cd and F poisoning,
occupational rheumatism, vibration lesions).

"An award to the widow of a deceased employee was
properly granted where the medical testimony was
sufficient to support the conclusion that Pb poi-
soning, contracted by the employee while at work,
was a contributing or aggravating cause of his
death.  The employee's duties required him to work
around Pb fumes and vapors which he inhaled.  Af-
ter being on the job for a long period' of time
he developed myeloma, and soon thereafter he died.
Medical testimony established that his death was
caused by the combined effects of the Pb poison-
ing and the myeloma.  The court, in holding that
Pb poisoning contracted while at work constituted
an occupational disease and was thus compensable
under the Workmen's Compensation Law, ruled that
the evidence was sufficiently competent to support
the award.  Sustained." (From Industrial Hygiene

        Medicine and Surgery 28:122-4; discussion,
        124-5 (Mar.), 1959.
The author discusses the problems of labeling po-
tentially harmful substances from the point of view
of a physician who has been a member of the Federal
Trade Commission since its inception.  On the basis
of his experience, he is in favor of the basic
principles of labeling established by the Manu-
facturing Chemists' Association, which include in-
formation of the name of the compound (preferably
true chemical name); words such as "danger" for
very hazardous compounds, "warning" for less
hazardous, "caution" for least hazardous, and "poi-
son" for highly hazardous; route of hazard, and
                brief description of simple methods of  avoiding
                the hazard, and simple  remedial methods of  treat-
                ment.   He  then discusses  certain Pb compounds  and
                the form  (dust or solution, paint) in which they
                are distributed.  Concerning paint hazards, Kehoe
                is cited  as estimating  that a  child of  3 yr must
                ingest  7  g of paint  (6  times that weight if it
                should  contain 5% Pb) to  get Pb poisoning,  but the
                ASA Standard would require that the child eat  210
                g  (7 oz)  to be poisoned.  This he considers a  safe
                standard.

                        discussion 109-11 (Mar.), 1959.
                The author points out that a figure of  standards or
                limits  has no significance per se but must  be  in-
                terpreted  in terms of analytical, toxicological and
                medical data applicable to each individual  com-
                pound.  From this viewpoint standards relating to
                Pb concentration in  air,  urine, blood,  water and
                paints  are discussed.

                In his  discussion of legal matters, the author
                gives advice to the representatives of  manufactur-
                ers and producers of Pb as to  their liability  to
                employees  and to the consuming public.   He  points
                to the  lack of uniformity in compensation statutes
                and the giving of medical testimony.  As to lia-
                bility  to  the consuming public, he points to the
                American Medical Association Committee  on Toxicol-
                ogy recommendation that a uniform state Hazardous
                Substances Act be enacted, questioning  whether
                there is  to be a federal  law or 49 state laws, or
                countless  municipal ordinances and regulations.

BIOLOGICAL ASPECTS OF LEAD

-------
 Since  1931  the listing  contains a paragraph  con-
 cerning anemia  due  to Pb poisoning.  An  anemia  is
 defined to  be  subject to compensation  if it  is  us-
 ually  normochromic  and  aplastic.  The  author points
 out  that  the word "usually" should be  omitted if
 compensation is limited to normochromic  and  aplas-
 tic  anemias for it  is ambiguous.  He argues  that
 if it  is  the intent of  the law that only normo-
 chromic anemias be  compensated, it should state
 so;  if it is the anemia found in Pb poisoning,  the
 wording should  state "anemia confirmed by globular
 counts."  In this connection, he cites one of his
 reports as having confirmed a severe anemia  in a
 case of Pb exposure to  be an aplastic  type,  accom-
 panied by stippled  cells; it was not normochromic.
 Therefore,  if compensations are granted  only for
 certain anemias, the presence of blood cells with
 basophil  granulations should be included in  the
 list of diseases eligible for compensation.

The testimony applies to a fatal case of Pb who
had the following signs and symptoms when seen by
his physician (with experience of  having  treated
 300 cases of Pb poisoning):   pains  in abdomen,
cramp-like type, pain in limbs,  headaches of
varying severity,  loss of memory,  constipation,
 loss of appetite,  nausea, history of vomiting,  and
 arteriosclerosis starting shortly after beginning
 the 4-mo treatment period,  which led to his death.
Upon questioning,  Pb was not determined in the
urine,  but albumin indicated the presence of ne-
phritis.   There was also hypertension.   Treatment
was by orally administered K iodide and Ca; also
Ca iv and symptomatic treatment.   The pathologistfe
 testimony included microscopic examination of the
 liver,  showing some cloudy swelling of cells,
vacuolizations in the cytoplasm and  faintly stain-
 ing nuclear structures;  aorta showed slight changes
 in the intima.   Traces of Pb were found in the
 kidney and liver,  using Lederer's  test, estimated
 to be 1/10 or 1/100 mg in ^200 g tissue.   Micro-
 scopic changes indicated a chronic  interstitial
nephritis.  Further questioning brought out that
Pb in normal urine, as reported by Kehoe, amounts
to 0.0138 mg/1.  Respondent's internist and path-
ologist gave testimony to the effect that it was
not possible to conclude that deceased had Pb poi-
soning, since many people who are never exposed to
Pb have Bright's disease.  Biochemist's testimony
questioned the method used for the identification
of Pb in tissues, having found in kidneys and
liver in Pb poisoning of from 10-20 mg/100 g.

A USPHS Advisory Committee for the revision of the
1946 Drinking Water Standards has proposed the re-
duction of the mandatory limit for Pb from 0.1 ppm
to 0.05 ppm because:  (1) Pb is a cumulative poi-
bon;  (2) daily intake of Pb in excess of 0.6 mg
may result in the accumulation of Pb in the body
at rates that increase as the daily dose increases;
(3) the amount of Pb  intake from  food sources is
probably approaching  an irreducible minimum,
whereas exposure from other sources, such as the
atmosphere is increasing; (4) it  is believed Pb
exposure should be reduced wherever possible.

In discussing the great discrepancy between  the
Russian and German MAC's of workroom air, with the
lowest almost always on the Russian side, the rea-
son advanced is the different approach to the
problem.  The Russians' medical theory is concen-
trated essentially on the response of the so-
called higher nervous activity to the chronic ex-
posure to minute concentrations of poisons,  by use
of very subtle  physical, biochemical and psycho-
physical methods.  The author wonders, however,
the extent to which such experimental and clinical
findings and proofs can be integrated into the W.
European medical studies in order to become  gener-
ally binding.
  In conclusion, the author states that how  far
the industries  have succeeded in realizing these
surprisingly low values is not known, and that ac-
cording to the  literature, considerable disagree-
ment between the norms and actuality may exist.
"Aside from any polemics, a total evaluation could
be at best only theoretical in the absence of own
comparative experience."  Among the tabulated sub-
stances for which MAC'b have been set, that  recom-
mended in Germany for Pb is 0.15 mg/m3, and  that
legally established in the USSR is 0.01 mg/m .

The review begins with the Law of July 2, 1928,
in which for the first time several occupational
diseases were made equal to industrial accidents.
The successive developments to the Law adopted  in
1957 are described; these include interpretation
and additional sources of diseases with expanding
technology.  Many ambiguities and inequalities
in indemnity in the earlier years were due to
lack of precision of exposure; eg, in the case  of
Pb poisoning, it was impossible to grant indem-
nity if the worker was employed in the manufac-
ture of white Pb paint  (basic Pb acetate).   In
time, the terminology was changed to the elements
in question and their compounds, eg, "Pb and its
compounds."

         TOXIC SUBSTANCES.  Proceedings of  the In-

         1-2:83-4,  1961.
 In  the author's  country,  MAC is defined  as that
 concentration which does  not cause even  the  slight-
 est  symptoms of  poisoning in the course  of daily
 work over  the entire  working life, by considering
 individual sensitivities  and factors affecting the
 resistance of the  organism to these  substances.
 In  support of this attitude, she gives an  example,
 based  on animal  experimentation, of  individual
 variation  to parathion; another deals with effect
 of  physical exertion  on resistance to small, near-
 threshold  doses  of TEL in rats.  Small,  repeated
 doses  in the group which  was exhausted by  swimming,
 produced a more  rapid intensification of the pro-
 cess of  inhibition of conditioned  reflexes,  and
 the  time required  for the conditioned reflex to
 die  down was shortened.   Rats trained to swim
 showed disturbances of the conditioned reflex
 activity after  a much longer time.   This shows
 that exertion which results in training  gives a
 higher resistance, while  exhaustion  lowers it.

The  industrial MAC values in air for numerous sub-
stances,  published in the USSR in 1960, are dis-
cussed and compared with  those established by the
American Conference of Governmental Industrial
Hygienists in 1959.  The values are set for gases
and vapors on the one hand and dusts and aerosols
on the other;  ths previous division of poisonous
and nonpoisonous has been abandoned.  The USSR
value for TEL is 0.005 mg/m3;  for Pb with its in-
organic compounds,  O.Ol mg.  A table of general
MAC values in community air gives 0.0007 and
0.0017 mg/m3 for Pb and Pb sulfide, respectively.

In view of recent interest in Italy in MAC's for
toxic substances, the author submitted a question-
naire to university  institutes, organizations
concerned with health surveillance, industrial
health services, etc, for their opinion on the
matter.  The following definition, based on that
of the American Conference of Governmental In-
dustrial Hygienists  in 1956, was adopted:  the
highest average concentration of a substance in
the work atmosphere  that can be absorbed without
damage to the health of people working 8 hr/day,
6 days/wk throughout their working life.  For
certain substances,  2 values have to be set, de-
pending on the form  in which they exist, or are
subject to absorption other than by inhalation,
such as TEL and others that can be absorbed through
the skin as well.  The author discusses the prin-
ciples and conditions for the values adopted, and
closes by saying that it is the aim in Italy to
maintain the MAC's at a practical level that could
be attained even by  the employer who has no in-
dustrial hygienist.  The MAC's already constitute
an instrument of prevention for the improvement of
working conditions.  If international agreement
could be reached as  to values and their interpre-
tation, their usefulness would be considerably
augmented.  A bibliography of selected articles,
applying to a number of substances, including Pb,
by Italian authors is appended.

which are considered harmful, but do not rub off
easily, may be used, provided that a sheet of white
or waterproof paper is placed between them and the
food.  Granulated metals, small shot or bird shot
used to clean receptacles and containers intended
for food, etc must be free from Pb.

The author describes briefly the pattern he has
followed for many years in the routine check-up and
presents the graphs which repeatedly occur at the
onset and in the therapy with CaEDTA of Pb intoxi-
cations.  In exceptional cases there will be a
break away from these graphs, an example of which
is presented in the paper.  The author claims that
the graphs, as presented, never failed him in his
experience as an occupational physician.  In a
case of chronic Pb poisoning, treatment with
Ca2EDTA seemed to be unsuccessful although large
quantities of Pb were excreted.  The suspicion
arose that the patient continued to ingest Pb.
When compensation for sickness was stopped, con-
tinued therapy with Ca2EDTA quickly resulted in
the patient's complete recovery.

Because of the possible additive toxic effects of
mixtures of industrial poisons  as compared to
pure substances,  the author suggests establishing
for their major component a MAC value somewhat
lower than that established for the pure substance.
A MAC of 0.15 mg for Pb in bronze fumes is recom-
mended instead of 0.20 mg.

The maximum average atmospheric concentrations of
contaminants to which workers may be exposed for
an 8-hr working day without  injury to health are
 listed.  These  threshold limits are based on the
best available  information from industrial experi-
ence and experimental studies.  They are intended
 for use in  the  field of industrial hygiene and
 should be interpreted and applied only by persons
 trained in  this field.  These values are reviewed
 annually by the Committee on Threshold  Limits for
 revisions or additions as further information be-
 comes available.  The recommended threshold values
 for Pb and Pb arsenate in approximate milligrams
 of particulate  per m3 of air are 0.2 and 0.15,
respectively.

 poisoning, especially in  the jewelry  industry, as
 follows:   dust suppression during milling and agi-
 tating of  enamel powder by local exhaust ventila-
 tion or watering; brushes and styli should never
 be moistened with the lips nor cleaned with  the
 handkerchief; food and beverages should not  be
 brought into the work place; hands and face  should
 be washed  and the mouth rinsed immediately when
 work is finished; no persons <18 yr of age should
 be employed; regular medical examinations should
 be made; dressing rooms should be equipped with
 separate compartments for work and town clothes
 and with washing facilities; etc.

 Official values for Pb which are 0.2  mg/m^ of
 air in USA and 0.05 mg/m^ of air in Czechoslo-
 vakia may  be excessively high since the detoxi-
 cation mechanism is less dependable in sudden
 absorption of relatively large doses  than in
 regular intake of small doses used in pharmaco-
 logic experiments.  (From Chemical Abstracts 59:
 10682, 1963)

        FOR 1964.  Archives of Environmental Health
        9:545-54 (Oct.), 1964.
 The threshold limit values, as adopted at the 26th
 Annual Meeting of the Conference, Philadelphia,
 Pa., April 1964, refer to airborne concentrations
 of substances and represent conditions under which
 it is believed that nearly all workers may be re-
 peatedly exposed, day after day, without adverse
 effects.   The values are based on the best avail-
 able information from industrial experience, from
 experimental human and animal studies and, when
 possible,  from a combination of the three.   The
 threshold  limits should be used only  as guides in
 the control of health hazards and should not be
 regarded as fine lines between safe and dangerous
 concentrations.
  Although most threshold limits have built-in
 safety factors to guard against adverse effects of
moderate deviations from normal environments, judg-
ments must be exercised in the proper adjustment to
meet unusual conditions of heat, ultraviolet and
 ionizing radiation, overtime, and others.   The
limits should be interpreted and applied only by
persons trained in the field of industrial hygiene.
They are not intended for use, or for modification
 for use, as a relative index of toxicity,  by making
a ratio of 2 limits,  in the evaluation of control
of community air pollution or air pollution nui-
sances, in estimating the toxic potential of con-
 tinuous uninterrupted exposures, or as proof or
disproof of an existing disease or physical  condi-
tion.
  Generally,  the values  listed refer  to time-
weighted average concentrations for a normal work-
day, which might be exceeded, by certain amounts,
 for short periods of time.
  Referring to threshold limit values of mixtures
 (Appendix B) containing several hazardous sub-
stances, in the absence of information to the con-
trary, the effects of the different hazards should
be considered as additive.
  The recommended threshold values for Pb and Pb
arsenate in approximate mg/m3 of air are 0.2 and
0.15, respectively.  The tentative value for TEL
at overall exposure by the cutaneous route, includ-
ing mucous membranes and eyes, is 0.075 mg/m^.

The Threshold Limit Values as published ty the
American Conference of Governmental Industrial Hy-
gienists is criticized as follows:  (1) "The aver-
age concentration and the ceiling seem to be con-
founded;" (2) some figures seem to be too high;
(3) some values have not been revised for 20 yr or
more; (4) the fact that the toxicity of metallic
compounds varies with the state (fume or dust) in
which these are present is ignored.  The author in-
troduces some data on IIAC's established by Japanese
scientists.   For Pb, he quotes Horiuchi's value of
0.05 mg/m3.

        THE APPLICATION  OF SOME ANTHELMINTICS IN
        VETERINARY PRACTICE.  Journal of Pharmacy
        and Pharmacology 6:921-43  (Dec.), 1954.
 In veterinary practice anthelmintics are mainly
 used as adjuncts to the  control of parasitic dis-
 ease and as curative agents when prophylaxis either
 has not been practiced or failed.  As prophylactic
 agents anthelmintics are used to eliminate the sig-
 nificant burdens of harmful parasites and the pre-
 vention of their further accumulation to clinical
 or sub-clinical levels.  To achieve this the ani-
 mals have to be dosed periodically, though the
 numerous species of animals involved have their own
 special requirements for particular drugs.  It is
 well known that Pb arsenate and some others are
 effective no matter whether they are swallowed into
 the rumen or into the abomasum, while others must
 be swallowed directly into the abomasum.  Pb arse-
 nate as a cestode anthelmintic has been reported
 (Harwood and Guthrie) to remove tapeworms success-
 fully from chickens, but too toxic for general use.
 It was also successful for the treatment of Moni-
 eria infection of sheep, lambs,-kids and calves
 (McCulloch, Radeleff).  Habermann and Carlson and
Ward and Sales confirmed its value against M. ex-
pansa.  Since knowledge of its toxicity is too in-
 complete, caution should be exercised especially
 in pregnant animals.  Morgan et al, found a dose
 of 1 g to be 100% efficient against M. expansa in
 sheep while 0.5 g reduced the efficiency to 62%.
Pb arsenate is compatible with phenothiazine and
 the 2 drugs can be administered together.  Despite
 the high degree of efficiency against Moniezia, it
has been shown that Pb arsenate is ineffective
against the fringed tapeworm of ruminants,  T.
actinioides which lives in the bile ducts.   (135
references, 8 on Pb arsenate.)

        TATE.  Queries and Minor Notes.  Journal

        1266, 1955.
The questioner wished to know whether the local
application of Pb acetate or Sn acetate results in
any toxic manifestations.  The answer was:   Appli-
cation of either Pb or Sn acetate to the unbroken
skin causes no harmful effects of consequence.
Percutaneous absorption is unlikely.  In general,
only some organic Pb compounds penetrate the skin.
Damaged skin may react differently as to absorp-
tion chiefly with Pb, the more toxic of the 2
metals mentioned.  However,  the local application
of such metallic salts is not wholly unaccompanied
by physiological response. Rothman notes:  "Salts
of Pb,  Sn, Cu, As, Bi,  Sb, and Hg tend to form
compounds with the fatty acids of the sebum.  Thus
an originally lipid-insoluble compound in aqueous
solution may be transformed on or in the horny
layer into a lipid-soluble metal oleate.  The per-
cutaneous absorption, then, quantitatively depends
on this transformation.  The same reaction may
take place outside the  body to a larger extent if
the heavy metal or its  salt is incorporated in
ointment bases which contain fatty acids.  This is
one reason for the increased absorption of heavy-
metal salts from some ointments as compared with
their absorption from aqueous solutions."

It was shown that Pb arsenite is 86-100% effective
in this disease when given at dosage of 1 g/young
animal and 2 g/older animal; the above levels
failed to produce toxic symptoms.  In actual treat-
ment a dose of 0.3-1.0 g can be employed.  (From

fication was noted in kidneys, renal pelves and
calyces, urinary bladder as well as of  the cardio-
vascular system, liver and  spleen.  Unfortunately
this agent is too toxic to  have  clinical useful-
ness; however, further study of  chelates for use
as contrast roentgenographic agents is  suggested.

Dibasic Pb acetate had bactericidal action on
Salmonella typhosa, Shigella dysenteriae, and
Escherichia coli, and treatment of these bacteria
with this salt decreased their virulence markedly.
The antigenicity of the vaccines prepared with
thus treated bacteria was stronger than that of
ordinary heated vaccines.  Pb acetate could also
be an adjuvant with diphtheria toxoid and egg
albumin, representative protein antigens.   (From

Enlarging paper (9 x 12 cm) was Imprinted first
with the index finger as control, then with the
same finger following application of 0.01 g of the
ointment to be studied to the tip, and lightly
spread for 45 sec with the aid of a thin metal
spatula.  Contact with the paper was maintained
for 3 sec, prints were made in 4 rows of 5 each.
The paper was then developed, fixed, and dried
under constant conditions.  The results showed
that hydrophylic ointments had good adhesive prop-
erties; they were quickly absorbed by the skin.
Ointments containing hydrocarbon gels, lipogels,
lanolin, or mixtures of these were found to have
varying adhesion, which was increased with in-
crease in lipophyl per cent content.  Because of
changing amounts and ratios, the influence of
solid material content (fatty oils, soaps, etc)
could not be determined with absolute accuracy.
Viscosity of the base also affected the adhesive
properties of an ointment: the more viscous and
firm liquid (such as lanolin) based ointments were
more adhesive than the more fluid based (such as
liquid paraffin).
  It is recommended that evaluation of protective
ointment qualities should include experimentation
in industrial conditions as well as in the labora-
tory.  Since these analyses in effect only deter-
mined whether the ointment in question was more
adhesive to paper or skin, further experiments are
planned using textiles, metals, glass and leather.

        DOGS.  Acta Radiological Diagnosis 2:517-
        22 (Nov.),  1964.
A method was developed of applying a thin coating
of  an adhesive plastic impregnated with  Pb as a
radiopaque material to the  endocardial surface of
a dog's heart, which  would  be   Derated  and com-
patible with survival, in order to study cinera-
diographically the  dynamics of  the cardiac valves
as well as changes  in volume and shape of the 4
cardiac chambers  in a dog recovered from thoracot-
omy.
  Six mongrel dogs, weighing 15-25 kg  each, were
used.  The Pb-adhesive mixture, consisting of fine
Pb  powder (measuring  =200 mesh), and Eastman 910
Adhesive, was prepared only a few minutes before
application to avoid  premature  polymerization.
This contrast medium  was applied to the  tricuspid
valves by opening the heart after resection of a
piece of the right auricular appendage.  The Pb-
adhesive mixture was  fixed  to the endocardial sur-
face and covered by endothelium.  Attempts are in
progress to apply the Pb-adhesive mixture without
cardiotomy by catheter introduced from the neck
or groin and to produce  stenosis of the  pulmonic,
aortic,  tricuspid and mitral valve leaflets by
application of the mixture.
  Surface-coating of  the intracardiac and intra-
vascular structures of an experimental animal
with such contrast medium offers a new approach
to the study of the intricate intracardiac dynam-
ics under normal and  abnormal conditions.

 urine are described, together with a modification
 for the estimation of lower concentrations.  The
 quantitative recovery obtained in the entrainment
 procedures of Ross and Lucas (1935) is confirmed.
 Applications to cases of suspected Pb intoxication

        (Apr.), 1950.
 A rapid method for the determination of Pb in
 biological materials is described in which almost
 the entire operation is carried out in a 8 x 1 in
 Pyrex test tube.  The material is subjected to
 rapid wet oxidation, ammonium citrate is added to
 prevent precipitation of earthy phosphates and
 interference by Fe, and the solution is rendered
 alkaline with ammonia.  Cyanide is added to pre-
 vent interference by other metals, chloroform and
 dithizone are added and the excess reagent removed
 by  alkaline cyanide.  The extinction coefficient
 of  the chloroform layer is then read photometri-
 cally.  Minor modifications are given for urine
 and for materials such as bone, rich in Ca phos-
 phate.  The method is accurate to within ±3.2%.

Samples were dried at 550-600°, dissolved in 10%
nitric acid, and precipitated Sn was filtered off.
Pb was determined in  the filtrate by the colori-
metric dithizone method; interference of other
heavy metals was prevented by addition of citric
acid and K cyanide.   It was essential to use Pyrex
ware and to adjust the pH to 8.5-10 before adding
dithizone.   Pb varied from 0.16-72 mg%, 5 mg% be-
ing the permissible content.  The paste scraped
off the inside of the tube after cutting it open
had a 10 times higher Pb" content than a sample
squeezed out of  the tube.  (From Chemical Abstracts

A very sensitive test for traces of Pb in the
presence of large quantities of Zn is based on the
fact that no ZnS is precipitated from strongly
ammoniacal  solutions by small quantities of H2S.
It is possible to detect 2 x 10~5 parts of Pb in
1 part of Zn,  while somewhat greater contents can
be measured colorimetrically.  The assay of Pb as
chromate in the presence of Zn is much easier and
more sensitive in strongly ammoniacal than in
acetic acid solution;  the limit of Pb/Zn is 2.5
x 10" .   (From author's summary)

In the June 1949 issue of Cahiers Medicaux de
1'Union Francaise, the authors, together with
Fortes, announced a simple method for the deter-
mination of porphyrin for the diagnosis of occupa-
tional Pb intoxication, which was named the uro-
silicotungstic-pyridic method, the technique of
which is described as follows:  Acidify 100 ml
urine with 2 ml pure HC1, add 10 ml 5% silico-
tungstic acid,  shake (a precipitate will form
which contains  porphyrin I and III),  wash the
precipitate 3-4 times with B^O (distilled), dis-
solve in 4 ml pyridine, add 5% ethyl acetate,
shake carefully, and examine in Wood's light.  A
red fluorescence indicates >4 yg porphyrin in 100
ml serum; a green fluorescence indicates either
absence of porphyrin or <40 yg/1.  A positive
reaction was obtained in persons working with Pb,
and the results are presented in tables.

i'he polarographic method was applied to the analy-
sis of gelatins in order to increase the simpli-
city, rapidity and accuracy of the quantitative
determination of traces of Cu, Pb and Zn.  Ashing
at 450°, and dissolving at a suitable pH, practi-

Fe, Al, and phosphates in commercial gelatins.

By the method described, Pb in a 10-ml sample of
venous blood can be determined by spectrography
without addition of citrate.  In analyses of 34
samples of blood submitted to the author's labora-
tory (11 workmen's compensation cases, 22 acute Pb
poisoning, 1 with poisoning from waterborne Pb),
1 showed <100 ug/100 ml, 17 100-300, and 6 >300 yg
Pb.  The author considers values <100 yg/100 ml as
not pathologic, and >300 yg to warrant suspicion
of Pb poisoning even when signs and symptoms are
not present.

                veloped by Senellart is described briefly and
                evaluated in  comparison with counts of stippled
                cells.  In the comparison the  author  used his  3
                categories:   (1) for those who are  not at all  ex-
                posed, (2) relatively little exposed, (3) highly
                exposed workers.  In the method recommended by
                Senellart, the division was based on  the  yg Pb/1-
                urine.  The comparison is tabulated.  The author
                states that if he had to choose between the 2
                tests, he would still prefer the basophilic stip-
                pling counts.

                The usefulness of de Langen and ten Berg's  method
                for determining an increase of urinary copropor-
                phyrins was tested in 715 workers in  industries
                using Pb, including plumbers,  Pb-founders,  paint-
                ers, color-grinders, enamel burners and composi-
                tors.
                  A slightly  increased excretion of porphyrin  was
                observed in the urine of 17 workers,  and  a  more
                pronounced increase  in that of 12.  Because of
                possible errors, quantitative  determinations were
                carried out in all instances in which limit values
                or positive results were obtained with the  afore-
                mentioned method; pathologically increased  24-hr
                amounts were  observed regularly.  The maximum  val-
                ue was found  to be 1,631.9 yg.

  With  the reservation  that  there are  other  dis-
eases which may be  responsible  for  increased renal
excretion of porphyrin, the  described  rapid  method
for  determining an  increase  of  urinary copropor-
phyrins is particularly suited  for  serial  examina-
tion of workers   in industries  using Pb.   (From

The  described method involves dry ashing of  the
samples,  preliminary separation of Pb  as the di-
ethyldithiocarbonate complex and its determination
absorptiometrically by the mixed color  technique.
Destruction of organic matter by dry ashing  under
controlled conditions has been  investigated  and
shown not to result in any significant  loss  of Pb
from flour.  Quantities of Pb of <1 ppm were esti-
mated with good duplications of results.   In the
samples of flour examined, the  normal  range  of Pb
was  from  0.03-0.20  ppm  (av 0.10).   (From author's

Because many methods involving  photometric analy-
ses  are highly erroneous,  the author checked  the
method he uses for Pb (Bambach  and Burkey,  1942)
for  reassurance and also summarized the method of
Ringbom (1939)  for  consideration by chemists work-
ing  in the field of industrial  hygiene.  This was
accomplished by plotting on logarithmic paper  the
per  cent  absorptance against a  given range of  con-
centrations,  the maximum attainable accuracy being
easily derived from the slope of the curve and the
optimum range defined by inspection of  the curvex
(concentration range with the steepest  slope).
The  author's  method showed optimum results, ie,
4-40 pg Pb/aliquot  of urine with a relative  analyt-
ic   error of 0.7%.  The range could be  extended to
higher concentrations, with an  increase in accura-
cy,  by measuring transmittancy  ratios.

In the sampling of air at  many  different points
in the factory, 18 1. were collected at the rate
1.8 1/min.  The temperature  and the relative hu-
midity were measured during  the analyses.  Analy-
ses were made of urine and blood of  46  employees.
Each sample of air was passed through traps with
10 ml of nitric acid.  The Pb content of each sam-
ple was then measured directly by means of a po-
larograph.  The procedure for determining Pb in
the blood by polarography is described  in detail.

        Monthly  11:94  (June), 1951.
In commenting on the Levine polarographic method
(1945) for determining atmospheric Pb, the author
found that if ethyl alcohol has been used to wash
precipitator tubes, deposits of gummy material are
formed, resulting in poor (high) polarographic
results.   Alcohol should be evaporated off before
adding the nitric and hydrochloric acids.
  In regard to the rapid screening test for uri-
nary Pb (Cholak, Hubbard, and Burkey, 1948), the
author feels that the ammonium solution of dithi-
zone used in preparing the buffer solution is
quite unstable and should be added to the solution
containing the citrate, sulfite, and cyanide as
soon as possible.  His experience showed that
allowing the dithizone to stand in ammonia even
only a few minutes results in decomposition to
such an extent that extremely weak colors with Pb
are produced.

Pb in blood and urine was determined by an inter-
mittent ac arc method with Bl as the internal
standard,  using lines Pb 2833 and Bi 2898 A.   The
sensitivity was 1 yg/ml Pb.   About 30 Mg Pb  was
found in 10 ml of blood of healthy Japanese  per-
sons by this method.   This value is higher than
the value determined by dithizone method.  (From

The problem of producing Pb glazes that will con-
form to the 5% solubility limit is examined with
especial reference to high Pb content types.  The
effect of the 2 main factors (variables) governing
the solubility of a Pb glaze (the intrinsic solu-
bility of the frit used and  the degree  of fine-
ness) is considered.  The paper also contains a
suggested quality specification for  Pb  bisilicate.

tact time and the effect of temperature on various
Pb bisilicate frits are discussed.  It is suggested
that the test requirements of the Factory Acts
might well be reviewed, to give greater accuracy,
especially since, for some time at least, glazes
with solubilities approaching the 5% limit will be
common in some sections of the pottery industry.

The new air sampler is a practical and efficient
device for the determination of airborne dust and
especially fume.  The materials used in the samp-
ler contain no organic matter and, therefore,
present no analytical  difficulties arising from
this source.  The sampler can be sealed immediate-
ly after the sample has been taken, so that there
is no chance of loss or contamination.   The in-
strument is recommended for use by industrial
hygienists for the determination of toxic particu-
late matter.  Tests to determine whether fumes
would be retained in the sampler included Pb
oxide fumes.

resulting in a significant discrepancy in the mean
values of the 2 groups in favor of the Hanson stain.
The values averaged 232 ±1.07 for the 1st  group
and 264 ± 1.05 for the 2nd, a yield  14% higher
with  the Manson stain.  This discrepancy may seem
small, yet it suffices to point to the Manson
stain as the superior method.
  Blood specimens from 129 persons were treated
with both methods and comparison of the counts had
the following results:  In 77 cases  (60%) the Man-
son stain showed greater counts;  in 31 cases (24%)
the Giemsa method showed greater counts; and in 20
cases (16%) both counts showed the same results.
This evaluation also speaks in favor of the Manson
stain.

that of a standardized powder containing known
amounts of Pb (50, 100, 200 ug/100 ml), the inter-

The Pb contaminants of the synthetic solution con-
taining the blood elements are eliminated by the
coprecipitation of PbS with HgS.   An AC arc is used
to excite the high frequencies.   The method is
accurate to within 5-10%.   The upper limit of nor-
mal Pb concentration in the blood is 70 yg/100 ml.

Pb in biological materials was determined spectro-
photometrically with Hilger E3 quartz  spectropho-
tometer, and the intensity of a Pb line at 2833 A
was determined with a microphotometer, using a Bi
line at 2898 A as an inner standard.   Samples
(1-2 g) containing vLO pg Pb/100 g biological
fluids (blood, feces, etc.) were determined with
an error of 10%.  (From Chemical Abstracts

In connection with air pollution investigations in
the Detroit-Windsor area, a qualitative and semi-
quantitative study carried out to determine partic-
ulate contaminants containing metallic elements in
total air is described.  Samples were  collected
daily for 6 wk at 31 stations; ^1200 samples were
analyzed for 21 elements in each.  Since time did
not permit the development of a quantitative method
for each of the elements (Si, Al, Fe,  Ca, Mg, Pb,
Zn, Mn, Cu, Ti,  Sn, Mo, Ba, Cd,  Cr, Ni, Sb, V, Co,
Be), the authors developed a semiquantitative
method.  The entire procedure, as described, was:
passing air through a high-volume pleated paper air
sampler, weighing the residue collected, removing
the deposits by washing with ethyl alcohol, wet-
ashing with concentrated HN03, and H2S04, treating
with HC1, adding to electrodes of a spectrograph,
and evaluating the concentrations by comparison
with spectrograms from prepared standards.  The

provide the accuracy of either the chemical or
spectrographic quantitative method, but, it yielded
results which were adequate for statistical analy-
ses to obtain the desired information for the

tion device for subtracting blank curves from
those obtained on samples.  Using this device,
diffusion currents for Pb have been measured in

The Gor'kii Institute of Labor Hygiene and Occupa-
tional Diseases had proposed that the MPC of TEL
be set at 0.005 mg/m3 (equivalent to 0.003 mg/m3
Pb).  Following a discussion of the disadvantages
of the sampling and determination methods speci-
fied by the Institute, the author proposes for the
collection of TEL air samples the use of conven-
tional equipment, such as a suction dust collec-
tor, a high velocity flowmeter, corrugated tubes
as adapters for cotton filters to retain metallic
Pb and Petri tubes containing 10 ml alcohol for
the absorption of TEL.  The set-up as described
enables the aspiration of 600-720 1. air in 1 hr.
The alcohol from all Petri tubes is poured into
1 container and TEL is determined by the usual
method.  The cotton from the corrugated tubes is
treated with HNOj and the metallic Pb is deter-
mined.  Up to 1 m3 could be aspirated in 1-1/2 hr
by this method and to accumulate sufficient TEL
for a precise determination.

For estimation  of Pb in blood, NH^ citrate and
NH4 hydroxide are added to pH 10-11, then 10% KCN
is added to turn the solution green to yellow
(thymol blue) and a large amount of NH^OH-HCl add-
ed.  The mixture is kept for 5 min and the method
continued as usual.  If a precipitate forms on the
addition of NH^ citrate, as takes place in the
case of bones and urine, the solution is acidified
with 0.3N HC1, 5 mg CuSO^ added, H2S passed
                 through solution  for  3-5 min,  the precipitate

                 A  polarographic method of estimation  of Pb in

                 The principle of  the  method lies in the absorption
                 of Pb  onto the ion  exchanger and its  regeneration
                 in 7N  HC1.  If 25 ml  of urine and 5 ml  of  ion  ex-
                 changer are used, this method will  allow the Pb to
                 be estimated  within a range of 1-10 yg,  ie, 4-40
                 ug%.   If a greater  or smaller quantity  of  urine or

                A monocolor dithizone method for the determina-
                tion of Pb in blood is described.  The main points
                in which the proposed method differs from  the
                usual dithizone method are the  following:   (1)
                Extraction of Pb with dithizone is performed at
                rather high pH values (10.5) and (2) the Fe is re-
                moved after mineralization of blood by means of
                2% aqueous cupferron solution.  The first  modifi-
                cation increases the sensitivity of the method and
                at the same time dispenses with  the necessity of
                washing the Pb dithizonate solution to remove the
                excess dithizone before measuring the extinction.
                The cupferron extraction eliminates all the possi-
                ble sources of error which are  connected with the
                presence of Fe.
                  The statistical treatment of  the calibration
                curves shows that the method is  reliable,  sensi-
                tive, and precise.  The standard error of  a single
                determination is not more, than  ±7 ug for Pb con-
                centrations from 25-500 yg/100  ml of blood if the
                measurement of the  optical density is performed
                with a Beckman spectrophotometer at 520 my.
                If 2 parallel determinations are made in each
                analysis, the standard error may be reduced to
                ±5 ug,   (From English Summary;  Archives of Indus-

BIOLOGICAL ASPECTS OF LEAD

-------
Determination of porphyrin  in  the  urine  is  a  re-
liable  test  in  the  early diagnosis of Pb intoxi-
cation.  A rapid method for determination is  de-
scribed.  Porphyrin  is extracted from the urine
and  its  fluorescence under  UV  light  is examined
and  compared with standard  solutions containing
100  ug%  and  1000 pg% porphyrin.  With some  prac-
tice, 2-3 porphyrin extractions can be done simul-
taneously.   The entire procedure takes less time
than the preparation and examination of  blood
smears  for stippled cells,  and the results  are
more reliable.

Difficulties encountered in carrying out  the ref-
erence method are minimized by a modified method
in which the wet-ashed sample is extracted with
dithizone in toluene and the color complex meas-
ured directly in a photoelectric colorimeter
against standards.   In an alternative method a
dithizone-chloroform extract is obtained, 1/2 of
which is measured directly  in a Spekker  colorim-
eter and 1/2 measured after shaking with  dilute
^SO,/,.  The  difference between the readings is the
reversion value; this is compared  against rever-
sion values  of  standard amounts of Pb.

Various  methods are  outlined for the determination
of Pb in solutions  derived from the attack of  HC1
on Pb frits.   A chromate method, with gravimetric
or volumetric finish, has  been found satisfactory.
An investigation into the effect of contaminating
ions  on  this  method  is included.  Fe, Sn, and  Ti
are found to  yield  high results due to  coprecipi-
tation.   The authors conclude  that  the  accuracy of
the chromate  method  is as  good as that  of the  sul-
fide-sulfate  method, provided  that  certain inter-
fering ions  are absent.   Because of its simplicity
and increased rapidity,  determination may be com-
pleted in 24 hr.  If, however, other ions are in
the solution, from which the Pb is  to be precipi-
tated, then the method is  not  as reliable as the
sulfate  method.

Ca phosphate or Ca carbonate  entrainment was
shown to be a satisfactory way  of removing  traces
of Pb from solution and enabled Pb to be deter-
mined with sufficient accuracy  to satisfy recent
legislative requirements.  The  dissolved Pb may be
estimated as PbS or with dithizone.  If >1  ppm of
Fe is present, either it must be  removed or the Pb
precipitated as oxalate.

cipitate the ions of the group when  the  container
charged with the stock solution of the  ion is
placed on the carrier beside the reagent container,
a 1:1 HC1 solution is recommended as group pre-
cipitant.   Other reagents were ammonium  acetate
and K cyanide.  For Pb, 2 confirmatory  tests were
performed, ie, the dithizone and the K  chromate.

I.  Fresh NaCN solutions used in determining Pb
were found to suppress the extraction of Pb by di-
thizone.  This action is probably due to the pres-
ence of S in the NaCN.  As little as 0.003% shows
the effect, and can be minimized by aging the NaCN
solutions for at least 1 wk.
II.  The substitution of HC1 for HN03 in the solu-
tion used for collecting air samples for deter-
mining Pb provides satisfactory control of  Sn
occurring as a component of the Pb-bearing materi-
al sampled.  The therapeutic im administration of

Only recently have membrane filters become avail-
able commercially and used in the field of sani-
tary bacteriology.  This report deals with an in-
vestigation for industrial hygiene application,
since a recent Russian article described their
use for dust sampling.  As summarized by the au-
thors, comparative dust counts with the use of
membrane filters and the midget impinger indicate
that comparable counts may be obtained with the
filters with an appreciable saving in time, labor,
and equipment.  Acid mists and metal fumes (in-
cluding Pb) may be collected at nearly 100% effi-
ciency, and in many cases sufficient sample for
analysis may be collected conveniently with a
600 ml handpump.  Applications to particle size
separations and electron microscopy are subjects
for further investigation.

Determination of trace elements in a variety of
materials usually require enrichment of the ele-
ments, sample conversion to a form suitable for
analysis, and different spectrochemical calibra-
tions.  A method is described whereby organic com-
plexing reagents are used for the separation and
enrichment of 14 trace elements, including Pb,
along with In, which is the internal standard and
base material for the direct current arc spectro-
graphic analysis.  The elements are present as
oxides in arcing mixtures with a constant base ma-
terial, regardless of the type of the original
sample.  Thus the same spectrochemical calibra-
tions can be used.  These methods have been ap-
plied for >5 yr to analyze widely different types
of samples such as waters, snow, rock and minerals,
soils, coals, petroleum, plant materials, and bio-
logical tissues and fluids, in geochemical, agri-
cultural, and medical research.

                The title method for the determination of Pb in
                air, water, and biological materials is described.
                The accuracy of the method was established, after
                addition of 2.0, 5.0, 10.0, 30.0 and 50.0 ug Pb,
                by the recovery of 2.0, 4.8, 9.7, 29.5, 49.5 ug,
                respectively.

                        FOR THE ABSORPTIOMETRIC DETERMINATION OF

                        78:571-80 (Oct.), 1953.
                The procedure involves wet ashing, extraction of
                all the Pb and Bi, if the latter is present, with
                dithizone, a preliminary separation from the bulk
                of the Bi, and a final absorptiometric determina-
                tion of Pb by the "reversion" technique.  Quanti-
                ties of Pb in the range of 0-2 ug can be deter-
                mined satisfactorily in the presence of up to 20
                Ug Bi and at least 100 pg Cu or Zn.  (From author's

                The method is suitable as a rapid test and gives
                results differing by not >0.1 ppm from those of
                the reference method.  The sample is evaporated
                with HN03, dry-ashed at 500°, 1/2 of the ash dis-
                solved in HC1, treated with fflU), and citric acid
                sufficient to dissolve any precipitate, and KCN
                and H2S or Na2S solution to a final pH of 6 are
                added.  The color produced is compared against
                those of standards.

                With a jet dust-counter 50-1000 ml of air is drawn
                and Pb dust is precipitated on a cover glass, dis-

                dissolved in a supporting electrolyte and measured

                dust is sucked through purified water in an im-

 (2) use of ammonium acetate wash solution  <7.0 pH;
 (3) contamination with chromate residues.   Proper
 tubes have been made available recently  for the
 method.  A proper wash solution is prepared by dis-
 solving sufficient ammonium acetate  (of  low Pb
 content) to make a solution ^1% in water contain-
 ing 1.5 ml 0.1N ammonium hydroxide/100 ml,  filter-
 ing, and using at a temperature of VLO°C.   To pre-
 vent contamination, special care should  be  taken
 to remove contaminants from tubes, stirring rods,
 stoppers, etc, before proceeding with color de-
 velopment.  Thorough cleaning of working area,
 equipment, and analysts' hands is also necessary
 after the mother liquor  from the precipitate has
 been decanted and discarded.

Because of the following causes,  many slides pre-
pared for stippled cell counts  were found to be
unsuitable:   the fixation time  was too long;  the
distilled water contained carbon dioxide;  poorly-
prepared smears.   To avoid these,  the author sug-
gested  measuring the fixation time with a chronom-
eter and limiting it to 3 min,  boiling the dis-
tilled  water for 5-10  min,  and  preparing  smears
according to the Manson method, modified  as  fol~
lows:   (1)  Use very clean slides, washed with
alcohol;  (2)   Make smears as thin as possible,
dry quickly;  (3)  Immerse slide in methyl alcohol
 for 3 min;  (4)   Dry for 5 min;  (5)   Prepare stain-
ing mixture as follows:  Solution I:   methylene
blue,  1 g;  boric acid,  2 g; boiled distilled water,
100 ml.   Solution II:   Na hydroxide (Codex) 0.28 g;
boiled distilled water, 100 ml.  Mix the 2 solu-
tions at the last moment, just  before use,  at the
 rate of 6 drops of solution I and 8 of solution II.
Add 30 ml double distilled water; the stain  should
be transparent.   (6)  Dip the slide for 10-15 sec
 into the stain;  (7)  plunge it immediately in
boiled  distilled water for washing;  (8)  dry in
air.

Experience gained in the application of  the  rapid
screening test (Cholak et al, 1948) has led to a
number of revisions which greatly improve its re-
liability and convenience, not only in monitoring
personnel exposed to inorganic Pb, but also those
exposed to organic Pb.  The discrepancies between
the findings by the old and the new method are in-
dicated in a table.  In this technique, designed
to be applied directly to freshly voided urine,
for workers exposed to organic Pb conversion to
inorganic forms is by iodine (I).  The conversion
procedure, which precedes the cited technique, in-
cludes placing a 40 ml sample in a centrifuge
tube, adding 1.5 ml I solution (150 mg KI in H20,
making acid to Congo red paper with 1:1 HNOj, add-
ing 75 g I, and making up to 250 ml), mixing,
heating 15 min at 80-85°, cooling to 20-25°, add-
ing 1 mg NaaSOa (20 g in 100 ml distilled H20), and
mixing.  Following addition of dithizone, measure-
ment is by photometer.  Bi, Ti, and Sn interfere.
Applied for ^2 yr, the new revised method proved
to be practical for the appraisal of the severity
of the exposure of the TEL-exposed workers.

A method is described for detecting airborne Pb
particles, designed to be quantitatively adequate,
simple, and suitable for use as a direct field
test.  The test requires 2 reagents, a 0.2% solu-
tion of tetrahydroxyquinone in 95% ethanol and a
buffer solution of pH 2.79.  For field use the
method would make the use of the hand-pump sampler
possible, or a small filter-paper holder in con-
junction with a small sample pump; 2 dropping
bottles containing the reagents, a support for the
paper, a blotter, and a set of color standards
would be required.  Other metals as well as Pb
give color reactions with tetrahydroxyquinone;
the number of these interfering metals is greatly
reduced by the buffer solution, and Cd is the only
one left to give serious interference.

substance in a solution of 11.066 g K iodide and
16.93 g I in 100 ml water contained in a train of

then run polarographically in 2N K chloride.

Details are given of a method for Pb solubility de-
termination, by precipitation of Pb as sulfide,
followed by determination as chromate.  The re-
sults of an investigation into its usefulness with
pure solutions and glazes is included.  The con-
tamination of the Pb chromate precipitate when the
Pb is determined directly as chromate is also in-
vestigated.  A survey shows that at least half the
glazes yield contaminated Pb chromate precipitates.
Analysis of these show that silica is the main
contaminant and occasionally metals of group III
and Ba cause some difficulty.

A method for the determination of Pb in foodstuffs,
based on extraction of the dissolved ash with a
solution of diethylammonlum diethyldithiocarbamate
in CC1, at a pH 7.0, is suggested.  The complex is
decomposed with acids and the Pb is determined by
extractive titration with a 0.0035% solution of
dithizone in chloroform.
  The method is more accurate than the usual sul-
fide technique and more convenient than the ab-
dorptiometric method with dithizone solutions.

A stationary Hg-plated Ft electrode in a rapidly
stirred solution has been applied to the polaro-
graphic coulometrlc determination of traces of
Pb  .  Once the equipment has been assembled and
calibrated, analyses of micromolar solutions can
be completed in <10 min each, with a precision of
^5%.  The method avoids the lengthy preparation of
reagent solutions and the tedious extractions en-
countered in the competitive dithizone procedure.
Furthermore, it can handle more diluted solutions
than those usually analyzed by dithizone (ie, as
low as 10 ^M).   (From authors' summary)

A method for the polarographic determination of Pb
in biological material was presented and evaluated
both on the basis of its quantitative validity and
on the basis of its usefulness.  The method was
found to be comparable in accuracy to the dithi-
zone method and less time consuming.
  Polarographic "in vitro" studies of the effect
of agents used in the chemotherapy of chronic Pb
poisoning on the extent of Pb ionization in the
plasma showed that BAL, K iodide and ammonium
chloride increased the extent of Pb ionization in
the plasma, that Ca chloride caused little if any
change, while disodium hydrogen phosphate caused
a marked depression.  The authors consider that
these results furnish insight into the possible
mechanism by which disodium hydrogen phosphate
effects detoxification of Pb in vivo and lend sup-
port to the theories concerning this mechanism.
The Pb levels found by polarographic analysis on
the 24-hr urine samples from persons with normal
and abnormal exposure to Pb in the Chicago area
coincide with the ranges established by Gant using
the dithizone method for a similar study.  It is
demonstrated that this method for Pb analysis ade-
quately covers the concentration range encountered
in industrial toxicological surveys for Pb. (From

The erythrocyte basophilic stipple count has been
proved to be a valuable laboratory aid in detect-
ing Pb absorption.  More recently the detection of
urinary porphyrins (UP), a simple procedure, has
been advocated as a more sensitive screening test.
In comparing the merits of the stipple count (SC)
and the UP test, it was demonstrated that the UV
light source was a most important variable in the
results obtained with the porphyrin test.  Employ-
ing a Hg lamp with a blue-purple ultra filter and
a core and coil ballast and using the method of
McCord slightly modified, comparisons were made
with the SC in 67 consecutive tests on battery
factory workers.  In these 67 tests, there were 29
which showed SC and 45 positive UP tests.  There
were 4 instances where SC were seen accompanied by
negative porphyrin tests.  On the other hand, there
were 21 positive porphyrin tests when no SC were
present.  From these figures, it seems probable
that the detection of UP, employing a suitable UV
light source, is a more sensitive procedure than
                the count of SC in the detection of Pb absorption.

                The Committee recommends the use of the mono-color
                technique for the assessment of Pb in foodstuffs.
                An assessment can additionally be made with a  tin-
                tometer or even by nesslering.  The results of
                tests made on cocoa and  syrup are shown in tables.
                The Committee expresses  the hope that the method
                will be tried extensively and that further work
                will confirm it as a standard or referee method.

                1 cc of a precipitating reagent and 0.2-0.3 cc
                concentrated ammonium hydroxide.  After centrifug-

                determination of Pb in blood and describes the
                polarographic method he developed and its modifi-

                Pb in urine is much more complicated because of

The dithizone titration was used in the method de-
scribed.  In order to eliminate certain difficul-
ties, the organic substance present in the sample
is destroyed by wet ashing with HNO^.  The residue
is taken up with HC1  (1:1); following addition of
NH OH, KCN and Na citrate,  the solution is taken
up with NH3 (pH 9-10) and from this solution, Pb
is extracted with dithizone dissolved in chloro-
form.  Dithizone, which in  this solution is bound
with Pb, is freed by a 1% solution of HC1 and then
titrated with a solution containing 5 mg/1 of
Pb(N03)2.
  Aside from the time required for ashing, the
determination takes <15 min and can be carried out
on 50 ml urine or 5 ml blood of normal persons;
this can be reduced to 25 and 3 ml for individuals
with Pb poisoning.  For air analyses, 20 1. suf-
fice.  The rensitivity of the method permits the

The 1st edition was prepared by a sub-committee of
the Industrial Hygiene Section of the American
Public Health Association in 1944.  The present
edition "represents the united thinking of the
Committee on Chemical Procedures,  Industrial Hy-
giene Section."  It is a complete revision of the
original manual,  expresses  current theory and
knowledge and outlines the  laboratory procedures
"believed to present  the most  modern methods,
equipment and materials generally available."
  There are 7 sections.  A short introductory sec-
tion refers to analysis by chemical and physical
procedures and the choice of method.  The proper
collection of samples is then described at some
length with stress on the precautions which the
analyst must take to secure a fair and accurate
result.  A section deals with the preparation of
samples for analysis by ignition or wet ashing of
biological materials such as urine, blood, feces
and tissues; of individual and mixed foods; of air
samples and dust and of pharmaceutical chemicals.
The recommended procedures of analysis are:  (1)
dithizone methods which are the only chemical
methods considered since they are regarded to be
the most accurate and capable of modification for
particular purposes; (2) physical methods of spec-
trography and polarography.  These types of analy-
sis are all described in detail with suitable ref-
erence to principles, equipment and apparatus.  A
selected bibliography completes the publication.

Polarography, being a simple, direct way of deter-

charging the serum with an optimum dose of Pb.

explain the technique.  The polarographlc wave
for Pb is well determined for concentrations of
5-8000 yg Pb/1000 cc or 1 in a million (sic).  Ad-
vantages of the method are simplicity, objectivity,
specificity, and exactitude not obtained by the
usual tests for Pb in blood and urine.  (From Bul-

 of Pb with mercaptobenzothiazole (MBTh) was adapted
 to a microtechnique.
  A 76%-180% excess of a 1% solution of MBTh in
 2.5% NH^OH is the precipitating agent.   This is
 added, with stirring,  to a beaker mounted in a
 water bath containing the unknown.   The precipitate
 is washed with 4-8 ml of 2.5% NltyOH.   The washings
 are tested until no excess MBTh is determined.   The
 beaker and filter stick are dried at 110° under  low
 suction.  They are air cooled for 25 min while
 still under suction and then weighed.  Specific
 details are given.  The maximum relative error is
 ±0.3% for the range of 3-8 mg of Pb.

 tion of the mixed-color dithizone method which
 consists of:  I,  Sample preparation; II, addition
 of reagents leading to color development; III,
 color interpretation.   All 3 phases were found  to
 be amenable to simplification:  I. The usual ap-
 proach consists of vigorous oxidation of all or-
 ganic material with strong oxidizing acids and
 heat.  It was found that the same end could be at-
 tained by  the precipitation of blood and liver pro-
 teins with 5% trichloracetic acid.  Between 75 and
 100% of the Pb known to be present in the blood or
 liver samples was always recovered in the centrifu-
 gates.  II. Conventional methods for dithizone de-
 termination of Pb require the addition of NH^ hy-
 droxide, NH3 citrate, K cyanide, and a chloroform
 solution of dithizone.  Simplification of these
 additions  consisted of the substitution  of Na hy-
 droxide and Na carbonate for NH-j hydroxide (in or-
 der  to achieve greater reagent stability) and the
 combining  of these and K cyanide into one aqueous
 solution.   It was determined that this aqueous  so-
 lution was stable for at least 7 mo when stored at
 room temperature.  A dithizone solution  of 8 mg/1
 was used with chloroflorm as a solvent.  This solu-
 tion was found to be stable for 5-6 mo when stored
                 in  a  refrigerator.   III. Most  conventional  dithi-
                 zone  procedures  require  the  use  of  either a colori-
                 meter or  a  spectrophotometer as  a means  of  trans-
                 lating color  into  Pb  concentration.   This phase
                 was simplified by  the use  of a series of color
                 cards,  each representing a specific concentration
                 of  Pb.

                 A new rapid method for the detection and semi-
                 quantitative  determination of  porphyrin in  urine
                 is  described.  The method  which  is  based on the
                 fluorescence  of  porphyrins,  is suitable  for routine
                 tests of  workers exposed to  Pb.  Extraction of
                 porphyrins  from  the  urine  is not necessary.  Inter-
                 fering fluorescences  are eliminated by a simple
                 coupling  reaction  using  Ehrlich's aldehyde  re-
                 agent,  and  addition  of Na  hyposulfite.  As  little
                 as  10 yg% porphyrin  can  be detected.  The time re-
                 quired is "VL-2 min/determination.   The findings
                 by  this method  compare very  well with the clinical
                 findings  as well as with the traditional methods.
                 They  are  also much better  than the  spectroscopic
                 method with which  only values  of >50 yg% could be
                 detected.

                 In  the method described,  the organic matter is des-

The  alkaline-earth  phosphates,  including  Mg-phos-
phate,  can be kept  in  solution  under conditions
suitable for  dithizone extraction of Pb,  by adding
Na hexametaphosphate.   This  facilitates the use  of
a simple dithizone  purification step in the deter-
mination of traces  of  Pb  in  a wHe  range  of foods.
A detailed procedure is given for determining
traces  of Pb  in  foods  but  the only  new feature is
the  use of the metaphosphate  to prevent or  delay
the  precipitation of MgNH4.6H20.

By the  method described,  30-40  blood samples can
be analyzed by 1 person in a  day.   If necessary,
1 or 2  can be completed in 45 min.   This  has been
accomplished  by  cutting the  time of preparing  the
sample  for the arc  ^50% (use  of partially oxidized
blood);  by reducing  the spectral background  to  the
point where its  measurement  is  unnecessary.  This
reduction has been  achieved by  the  use of a narrow
slit (10  u) and  N in the  analytical gap.  Freedom
from contamination, necessary for accuracy,  is
largely due to the  electrode  loading technique.
The  accuracy  of  the method was  established  by  ^300
blood analyses with this  method and chemically.

         SAMPLING LEAD  FUME.   A.M.A.  Archives of
         Industrial Health  11:243-50  (Mar.),  1955.
Several commercially available  analytical filter
papers were tested  to  determine which  are best
suited  for field sampling  of  airborne Pb  from  the
standpoint of resistance,  efficiency,  and uniform-
ity  of efficiency.  Tests  were made  with Pb  fume
produced by 4 different methods  comparable with
those found in practice.   Electron micrographs of
these fumes indicated  mean sizes  in  the 0.01-0.05
V range.  Discrete particles  as  small  as 0.005 y
were recognized, but the fields  contained large
numbers of aggregates,   some as  large  as 0.6  p.
The  collecting efficiency  of  5  of these papers was
>75% and  fairly  uniform (5% average  deviation).
For  convenience  they were  placed  into  3 resistance
groups.   The best in the low  resistance group
(<0.3 in H20/ft2/cfm)  was  Whatman No.  41;   in  the
medium resistance group the best was Munktell
No.   00,   (0.3-1.0 in H20/ft2/cfm); in  the high  re-
sistance group,  Whatman 42 and  44 and HA Millipore
(>1.0 in H20/ft2/cfm).   Collecting efficiency was
found to increase with  decreasing sampling  rate,
indicating diffusion as the principal separating
force.  No effect of fume  concentration on  effi-
ciency was noted except when  high fume loadings
were sampled.   In these cases,  fume was presumed
to deposit in the void  spaces of  the  filter media,
and  efficiency was increased by  the  filtering ac-
tion of the deposited  aerosol.   (30  references;

rt method is described for the determination of Pb
in urine which eliminates the necessity for time-
consuming precipitation and ashing.  Pb, as Pb
iodide, is extracted quantitatively from acid solu-
tion with methyl isopropyl ketone.  The Pb is then
removed from the ketone layer with an aqueous Na
hydroxide solution and is determined colorimetri-
cally by the dithizone method of Snyder (1947)
using the Pb-Bi separation of Bambach and Burkey
(1939).  The time required for each analysis is
^45 min.  The range of sensitivity of the method,
0.70 [,ig using a 22-mm cell and a Coleman Universal
spectrophotometer, is sufficient to determine the
microquantities of Pb found in mild, chronic Pb
poisoning which would otherwise be difficult to de-
tect.  By varying cell size the range may be in-
creased.

By the method described, Cu, Pb, and Cd in yg
amounts could be determined with a reproducibility
within 0.2%.  When the background count was made
definite and its ratio to the total count made as
small as possible, Cu could be determined within
an error of 1 vig.  Determination of a mixture of
Pb and Cd gave larger error.  (From Chemical Ab-

A new procedure is suggested for the quantitative
separation of Ag  and Pb   in a solution.  Add an
excess of Na citrate solution which will first
cause precipitation of the citrates of Ag and Pb
but the precipitations will redissolve as complex
citrates.  By addition of HC1, AgCl alone precipi-
tates out  and can be estimated gravimetrlcally.
Pb can be determined in the filtrate as Pb chro-
mate.

To prevent loss of Pb and Zn during storage and
the reduction in volume of the sample being trans-
ferred for analysis, concentration under field
conditions by means of coprecipitation with CaCO^
was made.  The precipitation of CaCO^ completely
absorbs the Pb.  The Ca(NO-j)2 solution resulting
from the precipitate was employed as the polaro-
graphic background in the determination of Pb.
The sensitivity of the method is 0.01-0.02 mg/1.

                This paper gives in considerable technical detail
                the authors' method for the determination of Pb
                in blood and urine which, it is claimed,  gives ac-
                curate results with 5 cc samples of  blood and 30
                cc of urine.  The accuracy of the method  is stated
                to be ±10%.  fhe sample is submitted to wet ashing
                with sulfuric, nitric,'and perchloric acids.  The
                ash is extracted with hydrochloric acid and the Pb
                determined by a  polarographic method.  Samples of
                blood from 220 persons, whose histories revealed
                no contact with Pb, were analyzed, with the fol-
                lowing results:  in 186 cases, values ranged from
                5-30 yg%; in 32, 31-50; in 2, 51-60.  Determina-
                tions of blood Pb values in 3 persons before and
                after breakfast showed that in each  the amount of
                Pb was increased after the meal.

Of the ^1,500,000 deaths which occur in the US
each year ^9000 (0.6%) are homicidal and only 45
of these are due directly to the use of poison.
Nevertheless, a laboratory investigating crime is
kept busy performing tests for the detection of
poisons.  The mere presence of a poison in an or-
gan is not sufficient to prove that death by poi-
soning has occurred.  Total quantity rather than
mere presence and evidence that the amount was
sufficient to cause death are important factors.
  For analyses, poisons are generally divided into
classes according to methods used to isolate them
(ie, Pb classified among the heavy metals).  In-
struments used for detection are:  microscope,
spectrograph (96 elements, including Pb, can be
detected), spectrophotometers, X-ray diffraction
apparatus (to determine nature of a compound, ie,
Pb acetate), electron microscope, and the polaro-
graph (for identifying metals, including Pb).

A method of determining total coproporphyrin (CP)
in the urine on a Beckman spectrophotometer was
observed for ascertaining the degree of Pb poison-
ing,   i'he method was simplified for purposes of
routine analysis, partly by a single extraction by
hydrochloric acid from ethyl acetate extract and
determination of the conversion factor, and partly
as a rapid, semiquantitative determination with
the visual comparison of the intensity of fluores-
cence with the scale of standard solutions of CP,
with a wavelength of excitation radiation of 405 m
y.  Radiation of this wavelength can be obtained by
filtering the spectrum of Hg lamp through a fluid
filter of the Cu-ammonium complex.  The difference
in the CP values found on extraction with ether
and with ethyl acetate is discussed and explained
by the easier extraction of the precursor of CP
into ethyl acetate.  (From Abstracts Prague Insti-

The staining solution consists of a saturated solu-
tion of methylene blue in 95% alcohol, buffered
with a distilled water solution of Na and acid
veronal.  Very thin smears of blood are used,
fixed by plunging for 3 min in 90% alcohol, air-
dried rapidly, immersed for 20 min in the buffered
methylene blue, then washed in distilled water and
dried.  This method yields a greater number of
basophilic erythrocytes than can be obtained with
May Grunwald Giemsa stain.  The blood smears can
be processed the same day or on subsequent days
without any marked variation in numbers.  Concern-
ing the counting procedure, the author deems it
advisable that all hematologists adopt the same
notation.  He does not consider the reference of
the percentage of stippled cells to white cells
recommendable; reference should be to 1000 or
1,000,000 red cells.  Change of work should be in-
uicated at 2.5 basophilic erythrocytes/1000; Pb
poisoning should be suspected at counts >0.5/1000,
He also calls attention to a factor that to his
knowledge had not even been reported, which is that
there is a considerable difference in the percent-
age of stippled erythrocytes depending on whether
counts are made on venous or peripheral blood.  As
an example, in a Pb founder, 9.8 stippled cells/
1000 erythrocytes in venous blood vs 3/1000 in
peripheral blood were found.  For this reason, the
site of blood sampling must be recorded, and it
would also be necessary to establish threshold
limits for basophils in peripheral blood erythro-
cytes as well as for those in venous blood.

It was found that the precipitation of Ph"1""1" with
(NH4)2S04 is unsatisfactory in qualitative analy-
sis, since the PbS04 may fail to precipitate for
various reasons, or the precipitate is often not
recognized.  Precipitation of the Pb"1"1" as PbCr04
in dilute HN03 at a pH of  4-6 is suggested.  This
method allows determination of 14 yg Pb in 1 ml
solution.  (From Chemical Abstracts 52:11657,

Methods which include the  use of ion-exchange
resins were developed for  the quantitative deter-
mination of porphobilinogen (PEG) and ALA in
urine.  PEG is determined  colorimetrically with
Ehrlich reagent and ALA is determined by condens-
ing it with acetylacetone  to form a pyrrole which
reacts with a modified Ehrlich reagent.  The error
of the method  is <5% and the limit of detection
in a 1-ml sample of urine  is 1 yg PEG and 0.5 yg
ALA.  ALA has been found in high concentrations
in the urine of patients with acute porphyrla and
has also been detected in  normal urine.  Some of
the factors influencing the selection of optimal
conditions for the Ehrlich reaction are discussed.

A method is described for  the dry ashing  of  food
materials and the colorimetric determination of Pb
and Cu in the solution of  the ash obtained.  Ini-
tial sulfation of the sample before  ashing permits
the ashing to be carried out up  to a temperature
of 550"C without loss of Pb or Cu.   Ashing is  fur-
ther speeded up by crushing the  charred material
to a powder, and a suspension of Mg  carbonate  is
used to increase the bulk  of small ashes.  Inter-
ference during the determination of  Pb caused  by
the alkaline-earth phosphates normally present in
food materials is overcome by the addition of  Na
hexametaphosphate solution before neutralization.
When large amounts of Ca sulfate are formed, the
ash is rendered completely soluble by a preliminary
treatment with hot Na carbonate solution.
  Results of duplicate determinations by  dry-ashing
and wet oxidations are listed for the following
food products:  honey, malt, glace cherries, jam,
milk powder, condensed milk, milk crumb,  cocoa
powder, gelatin, glyceryl  monostearate, wax and

centrations ranged generally from 0.10-0.48 ppm;
glace cherries contained 0.65,  glyceryl monostear-
ate,  1.05;  2 chewing gum bases had contents of

It is possible to polarograph Bi, Cu, and Pb simul-
taneously in a medium of HC1  (1:3) and 10% tartaric
acid.  The potentials of semiwaves are correspond-
ingly equal to -0.12, -0.24, and 0.42 v  (bottom Hg).
The presence of ^SO^ and of excessive HC1 does not
interfere.  Pb can be polarographed with gelatin and
without it, taking into consideration that gelatin
reduces the diffusional flow of Pb.  This method
permits determination of any amount of Pb. It is
possible to determine Pb at 350 mg/1.  (From Referat.

 the use  of Cd(CN)2 is  excluded, Cu is previously

 A  speedier and more accurate method for the  deter-
 mination of Pb in air and biological material is
 described.   It was found than an overall saving
 in time of  25% was effected by this modification.
 The time required for preparation and ashing re-
 mained the  same but time was conserved by elimina-
 ting the transfer from ashing beaker to separatory
 funnel and  by reading percent transmission direct-
 ly in the colorimeter rather than estimating the
 mixed color by visual comparison with a set of
 standards.   Increase in accuracy was confirmed by
 comparing results from both the visual and colori-
 metric methods.  The comparison between the 2
 methods was made using pooled blood samples in-
 stead of pooled urine samples and essentially
 the same result was obtained.  The colorimeter
 proved to be slightly but definitely superior to
 the visual  method of Pb estimation.

 The author analyzed 'VLSOO  blood specimens, 800
 urine samples and 350  air  samples over a 3-yr per-
 iod.  From this experience he recommends polaro-
 graphic methods for analyzing large numbers of
 samples as a routine.  The recommended method has
 the advantage of being very simple and consists
 essentially of 2 parts:  (1)  partial wet ashing
 of the blood samples with  concentrated nitric
 acid, (2)  precipitation of Pb from filtered ox-
 idized solutions by Baker's method for urinary Pb
 determination.  In order to test the accuracy of
 the method 51 specimens in duplicate of blood with
 a known amount of added Pb were used and blank
 tests were performed at the same time.- Recovery
 was almost quantitative over  the range 20-200 yg
 Pb/100 ml of blood.  After establishing the valid-
 ity of the method, blood samples of exposed and
 nonexposed persons were analyzed.  Nonexposed per-
isons gave values from  19-36 yg/100 ml with a mean
 of 26.6 which corresponds well with the generally
 accepted normal range, while Pb exposed persons
 showed more or less hazardous concentrations of 65-
 342 yg/100 ml with a mean  of 98.  The concentra-
 tions were always consistent with known concentra-
 tions of Pb in air and urine and with the findings
 on coproporphyrin.

                The observed number of basophilic stippled eryth-

                  The results of this investigation are summarized

                borax stain.
                  It was possible  to improve the basophilic aggre-
                gation-test (McCord) by differentiating coarse and
                fine aggregations.  The number of the coarse aggre-
                gations corresponds  favorably with the BS count  in
                Pappenheim-stain.   It was also possible to improve
                 the dark-field examination of a methylene blue-Na
                bicarbonate stain  (Lane) by differentiating
                 coarsely and finely stipple erythrocytes  (criteria
                of Bastenier).  The observed number of the former
                 corresponds exactly with  the BS count according  to
                Pappenheim, or methylene blue borax stain  in  a
                 tight  field.  The  total  of  BS  in  a dark-field  cor-
                 responds  to the  total  of  reticulocytes as  counted
                in vital stain (brilliant-cresyl blue).  The exami-
                nation in a dark-field therefore yields 2 values,
                ie, the BS and the reticulocytosis, both criteria
                to evaluate the reaction of the body  to Pb absorp-
                tion.  The reliability of a single observation de-

 The conditions under which the natural radioactive
 isotopes  of Pb can be found in natural waters were
 examined, taking into account the possible behav-
 ior of the radiocolloids, and the chemical composi-
 tion of the water.  A simple radiochemical method
 of measuring 210pb,  212pb, and 21<4Pb is described,
 by the aid of which  it is possible to establish
 quantitatively the Rn content of natural  waters.
 Using this method it is also possible to  determine
 the Ra and 224ga that may be present.  The condi-
 tions are discussed  under which it is possible to
 relate the content of radioactive Pb in the water
 to that of U and of Th and to the emissive power
 of the rock from which the water issues.  (From

The purpose of the analytical studies was to deter-
mine whether Pb in blood and urine is in the form
of a chelate.  Initial experiments were conducted
with columns of cation exchange resin, then for
a more rapid evaluation of the Pb-complexing
powers of numerous compounds (allantoln, ammonia,
aspartic acid, billrubin, citric acid, creatine,
creatinine, cystine, glutamic acid, glycine, nip-
pur ic acid, HF, leucine, methionine, oxalic, phos-
phoric, tartaric acids, tyrosine, urea, uric acid,
acetic, acetylsalicylic, aconitic, p-aminobenzoic,
ascorbic, carbonic, formic, fumarlc, glucuronic,
gluconic, glutamic acids) potentiometric titra-
tions of the compound with standard KOH in the
absence and in the presence of Pb were carried
out.  Finally, the strengths of certain Pb com-
plexes were compared and the stability constants
of PbCit- (Kety) at 25 C° and 37 C° were deter-
mined by equilibrations against ion-exchange
resin.

several facts support a conclusion that Pb in
urine is bound as a strong neutral or negatively
charged chelate or complex.  No positive proof,
however, is given that such a compound exists,
and experiments with a number of possible chelat-
ing agents did not indicate that any of their Pb
complexes were present in the urine.  Citrate is
more likely than any of the others, but no con-
clusive evidence in favor of citrate was obtained.

                 By using a  semi-convection Hg electrode as an in-
                 dicator electrode,  constant-current potentiometric
                 titrations  were  carried out for Cu(II), Pb(II),
                 and Cd(II)  at a  low concentration such as 2 X
                 10~5M.  It  was  found that the titration with the
                 semi-convection  electrode was useful in analysis
                 of micromolar solutions, although it was less ac-
                 curate and  less  reproducible than that with the
                 dropping electrode.   Further, it was confirmed
                 that the titration curves obtained with the semi-

 A predetermined quantity  of  air is  passed through
 a sucrose  solution,  acidified with  nitric acid,
 contained  in Meyer absorption tube.   The  total
 amount  of  Pb contained  in air,  whether in suspen-
 sion  of fine dusts of Pb,  PbO,  Pb02  and PbS04  or
 fumes,  is  dissolved in  the above solution;  Pb  is
 determined colorimetrically,  and the color  obtain-
 ed  by precipitation of  Pb in the form of  sulfate
 is  compared with  solutions of known  content of Pb.

 fume  in  industrial  atmospheres  is  based on the for-
 mation of a purple  color  on  test paper impregnated
 with  tetrahydroxy-p-benzoquinone.   Results of  the
 field, dithizone  and  spectrographic methods are
 compared.  The  field  method  is  sensitive to about
 0.05  mg  Pb/m3.  Above ^5  times  the threshold toxic
 limit (0.2 mg Pb/m3),  the determination ceases to
 be  precise.  Airborne  particles of Pb oxide or
 Pb  of the same  size range as Pb fume,  which have
 not been formed by  condensation, can also  be de-
 termined by this  method.   (14 references)

Pb particles in air can be identified by a micro
spot test on membrane filters through use of an
alcoholic solution of tetrahydroxyquinone, which
forms a red precipitate with Pb.  The method, used
in a study of automobile exhaust fumes, shows ap-
plication possibilities in industrial hygiene prob-
lems  involving Pb and Pb products.

The method, applicable to the determination of Pb
and its compounds in workroom air is based on the
fact that degree of turbidity formed by the inter-
action between Pb ions and K chromate increases
with the increase of Pb ion concentration; com-
parison is made with the aid of a standard scale.
Sensitivity is 1 pg of Pb in analyzed solution
volume.  The method is not specific in the pres-
ence of Ba salts.  The limit of allowable concen-
tration of Pb and its compounds was set at 0.01
mg/m3 by regulation No. 279-59, issued Jan. 10,

                An instrument, the Billion-Aire, has been  devel-
                oped for continuously detecting and recording con-
                centrations of certain gases, among them TEL,  in
                the ppb range.  The Billion-Aire which  is  de-
                scribed and diagrammed in detail,  operates  on gas-
                eous conduction phenomena as affected by aerosols
                or subvisible smokes.  To be detected by the  in-
                strument in the 0-100-ppb range, TEL is pyrolyzed
                for breakdown at exit gas temperature of ^400°C.
                Higher sensitivity may be achieved by using ultra-
                violet radiation for breakdown; with this  arrange-
                ment, full-scale sensitivity is possible for  8 vg/
                TEL/ft3, ie, roughly in the 0-20-ppb range.

                The MSA Billion-Aire is capable of detecting  vari-
                ous toxic gases in the ppb range.  An ionization
                chamber is used as the detector and the mechanism
                of detection is the decrease in ion current as a
                finely divided particulate passes  through  the
                chamber.  The particulate is formed by  chemical
                reaction or pyrolysis of the gas to be  detected.
                Two typical applications are the detection of Nl
                carbonyl and TEL in the range of 0-50 ppb.  Both
                are converted by pyrolysis to the  elemental metal
                and/or oxides.  Experimental work  on TEL with an
                ultraviolet converter has indicated that even
                higher sensitivities may be realized.   (From  au-

                cent of the recovered residue  rather than as  the
                absolute metal content per volume; this  largely

 The  results,  obtained by  the  total Pb method and
 the  method  of  Taeger, in  the  routine analysis  of
 urine  from  Pb  exposed workers were critically  ex-
 amined.   The  differences  in the Pb values estab-
 lished are  presented  in a table.   For a quantita-
 tive determination  of Pb  excreted  by the organism
 only the  determination of  the total  Pb  should  be
 used.  This is the  only reliable method especially
 in view of  the application of chelates  in the
 treatment of  heavy  metal  poisoning since the pre-
 cipitation  method will only partially detect the
 complexed Pb.   A  simple method for the  evaluation
 of total  Pb by means  of the dithizone method is
 presented.  Values  from 100-150 ug total Pb/1  is
 accepted  as the limit value,  in contrast to 40 yg
 found  by  Taeger.  Any excess  indicates  increased
 Pb absorption. (From authors' summary)

powder which is soluble in water and aqueous alka-

composed by solutions of inorganic acids.   Its ad-
vantages over dithizone are its solubility  in
water, its simple use and the fact that it  does
not require K cyanide to mask interferences.

metric method, Pb alkyl is converted to Pb chlo-
ride and extracted from the gasoline by refluxing
with concentrated HC1.  After evaporation of  the
acid extract to dryness and removal of any organic
material by oxidation with HN03, Pb is determined

                 A rapid method  for the detection of Pb  in whole
                 blood,  requiring ^90 min is presented.   The method
                 consists of precipitation with trichloroacetic
                 acid, formation of cyanide, extraction  with dithi-
                 zone and spectrophotometric comparison  of the
                 color complex formed.  Differentiation  between
                 normal and pathologic concentrations by this meth-
                 od seems well defined.   Levels in 100 apparently
                 normal unexposed persons were <20 yg/100 ml, while
                 levels in  118 untreated children, diagnosed as
                 having Pb  intoxication, ranged between  42 and 310
                 yg/100 ml.

polarographic, photometric  with  dithizone,  and
spectrographic determinations is presented.  For
pig blood all 3 methods agree within ordinary
limits of analytical error.  Greater deviations
are obtained in analysis of liver, kidney and bone,

An ion exchange method for the determination of Pb
 in urine is described which involves (1) the auto-
matic feeding of urine into an ion exchange column;
 (2) the concentration of Pb from urine by a suit-
 able resin; (3) the elution of Pb from the resin
 by an acid, and (4) the subsequent determination
 of Pb by an acceptable method.  The results ob-
 tained by this method from the urines of Pb-expos-
 ed persons compare favorably with results obtained
 by other methods.  Recovery in Pb-spiked urine is
 90-100%.  (From authors' abstract)

        TORY EVALUATION OF METHODS IN OCCUPATIONAL
        HEALTH CHEMISTRY—THE DETERMINATION OF  LEAD
        AND QUARTZ IN LATIN AMERICA.  In Proceed-
        ings 13th International Congress on Occupa-
        tional Health, New York,  July 25-29,  1960

It was the opinion of the author  that an interna-
tional committee should be formed to establish
testing procedures and periodically evaluate  ana-
lytical methods by statistical means.  To support
this the author presented statistical evaluation
of data (quartz in synthetic mineral mixtures and
Pb in blood) obtained in various  Latin American
occupational health laboratories.  A replicated
series of blood samples were analyzed for Pb  in
each of 5 Latin American countries to study the
precision attainable.  The samples were prepared
in random order from citrated whole blood by  trans-
ferring known volumes of a standard Pb solution
prepared in all cases from stock  Pb nitrate solu-
tion.  Pb concentration in each sample was also
determined in random order by the method of
Bambach and Burkey (1942).  Amounts of Pb added
(excluding the unreliable results of 2 laborato-
ries) and averaged amounts found  in ug, respective-
ly, were:  4.0, 3.84; 8.0, 7.91;  12.0, 12.25;
16.0, 16.21; 20.0, 20.14.
  Using a variance test and a joint confidence  el-
lipse, the author showed that the data of 2 labora-
tories were not compatible with the respective
least square values determined from the average
results of the other 3 laboratories.  Based on
pooled results of the 3 laboratories showing  homo-
geneity, the author was able to determine a least-
squares fit to the standard curve for the analysis
of Pb in blood.  Thus, from the data presented,
along with that from the quartz analyses, the
author felt he had justifiably demonstrated that
well-established procedures, even when used by
trained personnel, to say nothing of untrained  or
new workers, may result in data that are erroneous.

Preliminary studies were carried out on the meth-
ods for simultaneous determination of various ele-
ments, including Pb.  N HC1 buffer was used for
simultaneous determination of Cu, Pb, Cd, and Zn
in the presence of Fe and Cr.  By use of 0.01%
gelatin/phenol suppressor and N2> good reproduci-
bility was obtained, the error in the range 1-5
ppm being for Cu, Pb, and Cd, respectively, ±4.3,
3.2, and 7.0%.  The use of nitrilotriacetic acid
as base electrolyte (4% weight/volume in 12.5%
aqueous NH3) was unsuitable owing to much inter-
relation of metals.  The methods of preliminary
treatments of sewage and sewage sludges in prepar-
ing samples for polarographic determination were
discussed, concluding that the currently accepted
methods of organic matter destruction are subject
to losses while the controlled decomposition pro-
cedure is too time consuming.  Discrepancies were
observed in preparation of sludges by acid diges-
tion or ashing of identical samples.  (From Chemi-

                A  formula for calculating the daily coproporphyrin
                (CP) excretion from a single spot sample is pre-
                sented.  It involves using a hypothetical figure
                for specific gravity (1.016), assuming that 1500 ml
                of urine is eliminated in any 24 hr, and then cor-
                recting findings accordingly.  However, if albumin
                and sugar are present, an additional correction
                factor must be applied since every 0.4 g protein
                or 0.27 g glucose/100 ml urine raises specific
                gravity by 0.001.  Four Pb workers  (A-D) were used
                to test this method by collecting 3 separate speci-
                mens from each on the same day.  Specific gravity,
                real values, and values for  specific gravity of
                1.016, respectively, were:   A, 1.016, 1632 mg/1,
                1632 mg/1; 1.019, 1800, 1516; 1.021, 1260, 960;
                B, 1.018, 1188, 1066; 1.009, 648, 1152; 1.014,
                840, 960; C, 1.026, 326, 201; 1.024, 412, 274;
                1.024, 518, 345; D, 1.015, 199, 212; 1.003, 25,
                133; 1.002, 15, 120.  It can be seen that results
                can only have a limited degree of accuracy, but
                the author feels the method  is adequate for all
                practical purposes.
                   A simple inexpensive method for quantitative
                CP determination in urine is also described.  A
                series of dilutions ranging  from 1/2 to 1/24 using
                distilled water as the diluent were made from 3
                samples of urine in which the concentration of CP
                was known, the total volume  of urine and diluent
                in each tube being 1.0 ml.   To each tube was then
                added 0.4 ml glacial acetic  acid and 1 drop water.
                After shaking the mixture in each tube, it was
                extracted with 1.0 ml ether  and allowed to stand
                in daylight for 12 hr, after which  the results
                were read under ultraviolet  lamp.  Results closely
                approximated the quantity actually known to be
                present.  In 1 test, titer values and real values,
                respectively, in yg/1 were:  1600, 1830; 1200,
                1188; 600, 648.  A 2nd series of 9 samples sub-
                stantiated these results.

A study was conducted to evaluate the accuracy of
the methods currently used in the measurement of
Pb in the atmosphere.  Air-Pb samples were pre-
pared on filter paper tape to simulate the appear-
ance of filters through which 1 m-^ air had been
passed.  Pb was added in amounts found in samples
above street level during moderate traffic condi-
tions.  Each sample consisted of 5 Pb-impregnated
spots and adjacent blanks.  Pb was then determined
by various methods of extraction and analytical
procedures  (spectrographic and dithizone methods).

A method is presented for the determination of Pb
in urine without requiring the ashing of the
urine.  As internal standard, In, is used in pref-
erence to Bi.  AN atmosphere is introduced around
the sample electrode to minimize the wandering
of the arc around the rim of the electrode and to
lower the spectral background on the plate.  The
accuracy of the method averaged ±0.013 mg Pb/1
urine with a maximum deviation of ±0.03 mg Pb/1
urine.  It was developed for the use in analytical
laboratories which require a high degree of versa-
tility.

ammonium pyrrolidine dithiocarbamate (Malissa and
Schtfffmann, 1955) and methyl n-amyl ketone at a
pH sufficiently low (1.5-4.5) to avoid precipita-
tion of the phosphates.  Since only the concentra-
tion of Pb in the ketone phase is required, the
partial emulsification which invariably occurs
does not affect the accuracy of the determination.
Recovery of added Pb from normal urine and results
of the method with those by the dithizone method
were in satisfactory agreement.  The method is
                well suited for measurement of very low Pb con-
                centrations (<0.1 ppm) since it is specific for
                Pb and yields a negligible blank value.  By using
                larger volumes of urine  (100-200 ml)  it is possi-
                ble to measure a Pb concentration of  0.02 ppm with
                a SD of 0.002 ppm.  The  method is also applicable
                to other heavy metals.

                This is a  general method, combining the techniques
                of Strel'nikova and Pavlova (I960), Frost-Jones
                and Yardley (1952), and  Ferro and Ham (1957).  Pb
                is converted  to anionic  complex with  HCl,  adsorbed
                on a strongly basic anion exchanger,  and eluted
                with distilled water.  Pb is precipitated with 1%
                aqueous Na chloranilate, and 5% Na2EDTA is used  to
                release the acid  chloranilate ion by  chelation of
                Pb; results are read on  a spectrophotometer  at
                530 my vs  a reagent blank.  The curve is linear
                for 50-250 yg Pb.   Due to the fact  that Pb chlor-
                anilate did not precipitate in the  substrate used,
                <50 yg could not  be determined.  Solubility  tests
                of Pb chloranilate  in various solvents indicated
                that by increasing  the concentration  of methyl or
                butyl Cellosolve,  the range <50 yg  could be  ana-
                lyzed.  This would  give  toxicologists and  indus-
                trial hygienists  a  less  tedious method than  the
                dithizone.
                  In the  later article  (by Wynne and  Burdick),  the
                authors used  a salting-out effect which made  the
                procedure  applicable  to  concentrations <50 ppm,
                using the  original  substrate.

 the addition of K  cyanide destroys the Cu complex
 while rendering the Pb dithizonate extractable by

 containing both metals, although such waters occur
 infrequently.  There is no interference from up to
 3 ppm Cl, 3 ppm chloramine, 2 ppm Fe, 40 ppm Zn,
 or 350 ppm alkalinity; if the alkalinity is >350
 ppm, however, it is necessary to add 4 ml acid

A survey and evaluation of analytical methods for
 the determination of Pb in air by the Analytical
Reference Service with 42 participating laborato-
ries is presented.   The participants were given
Pb-impregnated filter-paper tape made to simulate
 filters through which 1 m^ air had been passed.
 Five different extraction methods were employed.
 For determination of the extracted Pb, 3 used the
 spectrograph,  27  the mixed-color dithlzone proce-
 dure,  11  the monocolor dithizone procedure and 1
 a green monocolor dithizone method.   A pronounced
 effect of the  method of extraction on the results
 was  noted.  Wet ashing with nitric acid yielded
 the  greatest precision and accuracy regardless of
 the  method of  determination used.   Results from
 samples pulped in dilute nitric acid showed less
 precision and  accuracy and were generally on the
 high side.  High  ashing temperatures produced low
 results.   In overall precision, the mixed-color
 dithizone methods were slightly better than the
 monocolor methods.   Within the  conditions estab-
.lished for this study, the results indicated that
 the  nitric acid,  wet ashing method for extraction,
 together  with  a mixed-color dithizone procedure is
 the  method of  choice for determining Pb on filter
 paper  in  the 0-10 yg range.

 In commenting  on  Lindberg's article (Abstr.  No.
 2298) , the  author states that when Pb values in
 the  urine spot samples are evaluated it is most
 important,  from a practical viewpoint, to take
 the  specific gravity of the urines into considera-
 tion.  Corrections of the values of the samples
 according to Levine  and Fahy's  formula give better
 accordance  than do those proposed by Lindberg,
 when corrections  are made for urines with special-
 ly high or low specific gravity.  (From author's

method makes use of synthetic standards.  Soil
samples are diluted 1:6 and plant ash 1:4, before
loading on center post graphite electrodes.  The
diluent contains 1 part Li2CO-j, 1 part CaC03, and
2 parts graphite.  The emission source is an in-
terrupted arc,  the sample being the anode.  For
most soil and  plant samples,  the  sensitivity was
too low for a  direct  determination of Mo and Co.

McCord and Zemp described a method for the deter-
mination of the total Pb in urine using "wet ash-
ing" which shortened the ashing time to 30 min.
The above method was modified in order to increase
its stability and reproducibility.  Identical re-
sults were obtained when this method was compared
with one which involves complete ashing.  The
method can be used for the analysis of urine from
persons suffering from Pb poisoning even after
treatment with EDTA and penicillamine.

BIOLOGICAL ASPECTS OF LEAD

-------
The author recently described a direct-reading cur-
rent integrator and subsequently improved it into
a recording instrument, the I-Q recorder.  It can
be used not only for coulometric analysis but also
for other purposes.  The highest sensitivity range
is 10 yA; the reproducibility can be assumed to be
0.1%.  Integration is possible from input zero to
rated value.  Rapid determination of micro amounts
of Cu and Pb, 1-10 yg and 4-10 Ug respectively,
could be carried out.  The rapid determination of
0.9 mg of Pb and 0.8 mg of Cd from their mixtures
is discussed.   (From author's summary)

Tests for counting stippled blood cells were criti-
cally reviewed.  The author favors the staining
method by Hanson-Schwartz.  Stippled cells are
divided into those with coarse granules, those
with fine granules, and cells with a mixed form of
granules.  Data are given per mille or per million
of erythrocytes.  In evaluating the data, environ-
ment and clinical findings must be considered.

The absorbance curve for extraction of Pb by
dithizone in C^Hg has a maximum at pH 8 and de-
creases smoothly to pH 12, pH range 7.5-11.5 being
suitable.  Dithizone remains in the C6Hg layer
below pH 9.7, but is transferred to the aqueous
layer above pH 10.2.  (From Chemical Abstracts

In the method described for the detection, deter-
mination, and separation of Tl,  Hg, Pb, As, Cd, Cu,
Bi, and Sb a nitric acid benzene-acetone mixture
was used for the  flow system, and  tartaric  acid
as complexing agent.  Detection of cations  de-
pended on height  of ascent and dye affinity with
dithizone and ammonium sulfide solution.  The
method allows a qualitative analysis of heavy
metal ions in 1 operation and enables  a quantita-
tive evaluation of the chromatogram by comparing
sizes of spots with chromatograms  of known  metal
contents.  The method is applicable to the  analy-
sis of biological material; however, ashing is
necessary; certain foods can be determined
directly.

                A method is suggested for the spectroscopic analy-
                sis of plant matter which does not require pre-
                liminary ashing of the sample.  A ground, air-
                dried, weighed sample of the plant material is
                tamped into a cigaret casing and placed in the
                horizontal arc between C electrodes of an ABP-2
                apparatus.  Stabilization of the arc and the in-
                troduction of the casing from above insures an air
                current (20-30 mm ^0 column) controlled by a wa-
                ter manometer.  Sample weights of 0.2-1 g are
                taken for quantitative and semiquantitative analy-
                sis.  The current is fed by 16-18 amp ac.  The
                distance between the electrodes is 5-6 mm.  The
                rate for introducing the casing should not exceed
                60 sec for a 0.2 g sample and 145 sec for a 0.4 g
                sample.  Twenty-three elements can be analyzed in
                this way (B, Mn, Ca, Cr, Zn, Si, Sr, Mg, K, Mo,

As stated in the introduction, the title method is
especially convenient for Pb analysis in the ab-
sence of Bi.  The method was designed for highly
accurate analysis of minute amounts of Pb in bio-
logical materials; thus, all details erf the pro-
cedures for the collection and ashing of samples,
for the purification of reagents, and for" the
preparation of glassware and other supplies must
be followed carefully and routinely for best re-
sults.  The method has been used for 25 yr for the
analysis of body tissues and fluids, air samples,
paints and diverse materials.  A rapid procedure
for the removal and analysis of a known area of
paint film from a sheet metal surface is also pre-
sented.
  In addition to detailed description of the above
procedures, interferences in analysis are detailed,
and the results of replicate analyses by referee's
laboratory of Pb in blood and of those by 10 col-
laborating laboratories are tabulated.

Bi and Pb in blood or urine were extracted with
                a solution of dithizone in chloroform, in the
                presence of K cyanide, ammonium citrate and
                hydroxylamine chlorhydrate, at pH 8.5.  After
                stirring the mixture for 1 hr with a buffer so-
                lution at pH 3.4, Pb was determined colori-
                metrlcally at 520 my.

                Three categories of pollutants are considered in
                this review: (1) Pollutants having a direct toxic
                effect if present in the atmosphere in sufficient
                concentration for a sufficient period of time;
                (2) pollutants not present in the atmosphere in
                sufficient concentration to cause toxicity but
                creating nuisance due  to odor; (3) pollutants in-
                volved in the photochemical process occurring in
                the ambient atmosphere, leading to the formation
                of eye-irritating, vegetation-damaging, and visi-
                bility-reducing reaction products.  Pb belongs to
                the 1st group listed;  its concentration in non-
                polluted and polluted  air, respectively, is given
                as 0-10 and 30-40 yg/m3.  The collection of air
                samples for the determination of Pb is described.
                In view of the relatively small quantities of Pb
                in the normal atmosphere extreme caution in col-
                lection and analysis is mandatory to prevent con-
                tamination of samples.  A detailed description of
                the reagents for and the  procedure of Pb determi-
                nation, using the dithizone method, is included.

 original procedure with no loss  in accuracy.  Good
 recoveries were obtained in the  range of 60-150
 yg/1.  The authors note that it  has been the
 practice of  their laboratory to  report the exact
 concentration of any  sample showing =50 yg/1
 (because of  the discrepancy in the literature as
 to  the normal urinary Pb content) and to suggest
 analysis of  additional samples for confirmation.

 The substance to be analyzed (1 g) is decomposed
 by heating in the presence of 10 ml concentrated
 sulfuric acid and adequate amounts of H peroxide
 and perchloric acid.  After decomposition, the
 volatile products are removed and the residue is
 taken up in aqueous acetic acid.  Pb ion is iso-
 lated from weakly alkaline solution (pH 8.5); the
 extracted Pb dithizonate is decomposed at pH 4.6
 and the liberated Pb ion is determined in a weakly
 alkaline medium containing cyanide ion with chlo-
 roformic dithizone solutions.  (From Chemical Ab-

Known amounts (0.01-1 uM)  of Pb in solution were
placed on filter paper and developed with various
 solutions.  The paper was then dried at 90° and
sprayed with a 0.2% Na rhodizonate solution.  A

A method for the simultaneous determination of
 stable Pb and 210Pb in hair and bone samples is
described.  Hair samples are wet-washed with con-
 centrated nitric and perchloric acid and dissolved
 in H chloride.  After extraction with dithizone
 the total Pb content is estimated photometrically
 and 210Pb activity by a scintillation counter.
 Bone samples are ashed before extraction with
 dithizone.  Mean recoveries of stable Pb from hair
 and of 210Pb from bone were 96.4 and 93.3%, re-
 spectively.

In the course of control analyses of drugs of plant
origin carried out in  the Department of Galenical
Drugs in 1957, excessive contamination by heavy
metals was found repeatedly.  In 1956 the Ministry
of Health revised the  limits earlier specified by
the Pharmacopoeia Polonica III, setting them  (as
determined as Pb) at 5 mg/kg for tinctures, 25 for
liquid and 100 for dry extracts, and 10 for syrups.
  A method of determining Zn, Sn, Cu, Pb, and Fe
by paper electrophoresis is described in detail.
The limits of detection were within the range of
0.1-0.5 yg, using small samples.  For illustration
the percentages of the above metals found in vari-
ous samples obtained from drug stores are shown.
The Pb content ranged  from 0.005-0.01%.

A method is described for dividing soils into Fe
oxide, sand, silt, and clay fractions suitable for
trace-element analysis.  The oxides were extracted
under ultra-violet light by ammonium oxalate (pH
3.3), which dissolves goethite and other Fe oxides
but not gibbsite or boehmite; it also extracts
some soil organic matter and, probably, trace ele-
ments associated with it.  Two horizons of 2 brown
earths were analyzed spectrochemically for Ba, Co,
Cr, Cu,  Ga, Mn, Ni, Pb, Sr, Ti, V, and Zr.  The
extracted oxides were the fractions richest in
trace elements and contained large proportions of
the total Co, Cu, Mn, Pb, and V.  Except for Sr,
Ti, and Zr, the amounts of trace elements in the
sands were small and were distributed between the
silicate-mineral fractions in the order: sand <
silt < clay.   Pb results (ranges) in ppm and vg/g
of soil, respectively, were:  soil, 24-71 and

After pretreatment,  heavy metals were determined
 colorimetrically (Cu by diethyldithiocarbamate,
 Zn  by dithizone, Pb as sulfide, and Mn as MnO^)
or  titrated with EDTA (Pb and Zn).  The curves in
which is presented the content of  these metals in
natural waters of different pH values show  that
 precipitation occurs at pH 5.4-7.5 for CuS04, 6.0-
 8.0 for Pb(N03)2, 7.9-8.5 for ZnS04, and 7.7-8.5
 (with 0.1N NaOH) or 8.4-9.0 (0.1N  Na2C03)  for
MnS04.   The residual concentrations are:   Cu 0.2-
0.7, Pb 0.3-1, Zn 1-2,  and Mn 0.5-1 mg/1.   They
are increased  slightly at higher pH.  The precipi-
tation of Zn and partly of Mn in natural waters
starts at lower pH values than in  pure solutions.

                 Freshly voided  urine  (25-75 ml)  is  reacted with
                 about  1 ml  aqueous  ammonia to  raise its  pH to  at
                 least  10, centrifuged for 15 min and the resulting

                 is  then evaporated  to dryness, ashed,  and treated

                 larogram is recorded  at 25°C and the amount  of Pb
                 present is  determined by comparison with a cali-

                 The difficulty  of an  accurate  determination  of Pb
                 and Mn in body  fluids and organs is pointed  out,
                 mainly because  these  trace elements occur normally
                 only in the range of  yg/100 g, while  the inter-
                 fering substances are present  in relatively  high
                 concentrations.   A  new electrolytic separation is
                 described in which  Pb and Mn are precipitated  as
                 difficultly soluble dioxides and separated from
                 all other elements  by microfiltration.   After  dis-
                 solving the dioxides,  Pb and Mn  are determined by
                 the usual methods.  The procedure offers the ad-
                 vantage of  obtaining  small final volumes from
                 larger samples.   (From Deutsche  Zeitschrift  fur

 In the 0.1M perchloric medium che waves  of  Bi^+,
 Pb^-  and Cu2+ ion reduction generally interfere
 with the wave of  proton reduction.   In contrast
 the peak of the anodic oxidation  of the  deposit
 formed on the electrode permits the determination
 of traces of these ions and can serve as an  end
 point indicator in quantitative analysis by  vari-
 ous oscillographic methods,  eg, the coulometric,
 which gives results similar to the  dithizone spec-
 trophotometric  method.

 The determination  of  Pb in  plant  substances, using
 the dithizone method,  yielded too low Pb values.
 The method could be improved by modifying the
 process of ashing  of  substance and  by reducing  the
 pH value in the K  cyanide washing solution.  Fur-
 thermore,  dry ashing  should be replaced  by decom-
 position with sulfuric-nitric-perchloric acid.

The spectrochemical method presented consists of
evaporating a 25-ml sample to dryness,  ashing the
residue at 550°C, mixing the ash with graphite
and arcing by a standard dc arc technique.  The
method offers advantages over previously used pro-
cedures.   It may be used for the determination of
Fe, Al, Cr, Mo, Ni, Co, Pb, Sn, V, Cu,  and Mn.

        gest (Prague) 5, No. 5:33-5, 1963.
The significance of polarographic methods for the
determination of low concentrations of substances
in  the atmosphere and in biological material is
pointed out.  The polarographic determination of
Pb  in blood, as developed by Czechoslovak authors,
does not require preliminary mineralization of the
sample.  The Pb which is normally firmly bound to
the red blood cells and plasma proteins is brought
into solution by treatment with HC1.  After a few
simple operations, amounts of Pb as low as several
tenths or hundredths of a pg/ml can be determined
directly by polarography.  A sample of only 4 ml
of  blood is required.  A sensitivity of this order
can otherwise be achieved only by spectrographic
methods which require expensive equipment and
complicated procedures.  Several chemical methods,
such as the use of dithizone, have been used in
combination with polarography rather than color-
imetry.  The method is also very useful in the
determination of Pb in urine after mobilization
with CaNa2EDTA, even many years after the individ-
ual has been removed from Pb exposure.

The possibility of contamination of drinking water
by traces of heavy metals, salts of which have
been employed as stabilizers in polyvinyl chloride
used for the water pipes, poses the problem of a
rapid method of determination of microquantities
of these metals,  especially of those which have a
toxic effect.   In this  study,  the determination
of Pb, Cd, Sn and Zn is discussed.  Since most
plastics used for water pipes contain 2  or more
of these metals simultaneously, the polarographic
method was selected as  the most suitable one.   The
water sample was concentrated by evaporation,
organic matter was destroyed by adding nitric and
sulfuric acids and the metals to be determined
were coprecipitated with Ca carbonate.  The po-
larograms were taken with a Sargent XXI  polaro-
graph.  The average error of the procedure was
3.6% for Pb, 2.7% for Sn, 5.6% for Cd and 0.9%
for Zn.  The sensitivity of the method in mg/1
was: Pb, 0.015; Cd and  Sn, 0.005; Zn, 0.02.

 The  technique presently  used for detecting baso-
 philic stippling  of  erythrocytes in blood smears
 stained  with methylene blue is considered to have
 insufficient sensitivity, as the granulations  are
 very fine and difficult  to  see under  the micro-
 scope.   The  "enrichment" technique  developed by
 D.I. Goldberg (1948),  in which  smears are placed
 in  a humid chamber  for  slower drying, is recom-
 mended.  Also  counts/10,000  erythrocyts  are
 recommended  as this  enables the  technician to
 compare  quantitatively  the  stippled cells and  the
 number of reticulocytes.  A comparative study  of
 100  essentially healthy  individuals,  32 with
 radiation exposure,  and  31  with  exposure to  Pb
 gave the following values,  respectively:  reticu-
 locytes,  6.4, 7.9,  13.5/1000; basophils (without

The availability of the Pb Isotope (210pb) has
greatly increased the analytical sensitivity pos-
sible in experimental Pb poisoning, particularly
in organs that contain small quantities of Pb.  A
disadvantage is the necessity of holding speci-
mens for at least 35 days before counting    Bi,
its 1st daughter which emits a B of relatively
higher energy than that of 210pb.  The authors
found that ^^Pb activity can be evaluated prior
to secular equilibrium with 2i^Ri by separating
the 2 by means of dithizone at pH 3.8-3.9, and
holding the specimens at least 11 days before
counting.  Recovery of 210Pb is quantitative re-
gardless of the tissue involved when >4ng of
stable Pb are present in the aliquots analyzed.

Methods for the determination of Pb in biological
fluids are briefly reviewed.  Based on their ex-
perience in the Institute for Forensic Medicine
in Siena, the authors' preferred method  for  the
determination of Pb in urine is that  of  McCord
and Zemp  (see Abstract No.  3672) who  use methyl
isopropyl ketone for extraction.   Some slight
modifications are necessary when this method is
applied for estimation of Pb in blood.   Organic
matter must be destroyed by Kjeldahl  digestion,
methyl isobutyl ketone is used instead of methyl
isopropyl ketone and a Beckman DU spectrophoto-
meter instead of a Coleman one.  The method de-
scribed is very sensitive, requires <3 hr and
permits working with small samples.

in soils and plants.  The reproducibility of trip-
licate repetition is 12-18%.  Since only 10-12
min is needed for triplicate determinations, this
method is 3-4 times faster than photographic meth-
ods of spectral analysis.   (From Chemical Abstracts

        SPECTROPHOTOMETRY.  Atomic Absorption
        Newsletter 3:111-4  (Oct.), 1964.
A method for the determination of Pb  in  the or-
ganic phase of atomic absorption spectrophotometry
is described.  In the case of blood,  the method
involves only precipitation of blood  proteins,
addition of ammonium pyrrolidine dithiocarbamate
and extraction with methyl isobutyl ketone.  For
urine, the sample is simply acidified before ex-
traction into the organic phase.  The Pb contents
of blood from patients with probable  Pb  intoxica-
tion were determined by both atomic absorption
and the colorimetric dithizone extraction method;
the findings showed good agreement.   When the Pb
content in blood from 50 patients with no known
Pb exposure was measured by atomic absorption,
10% of those tested showed levels of  20  yg/100 ml
and the remaining 90% had lower levels.  The uri-
nary Pb concentration was <20 yg/1 in 74% of this
group, between 20-40 ug in 20% and between 40-60
ug in 6%.   The detection limit of the method is
^20 yg Pb/1 urine or /100 ml blood.  Ethylene-
diaminetetraacetate (EDTA) interferes with the
described extraction of Pb.   However, urinary Pb
in patients in EDTA therapy can be determined by
direct aspiration of the sample into  the flame,
provided the quantity of Pb is ,200 Ug/1-  Peni-
cillamine does not interfere with the usual

 The determination of trace amounts of Pb is based
 on a very intense luminescence of Pb chloride com-
 plexes at low temperatures.  The method permits
 determination of 1 ug Pb in 1 ml of a solution.
 Most metals when present in amounts 10 times those
 of Pb do not interfere, but trivalent Fe and biva-
 lent Cu in a similar excess will quench the fluo-
 rescence.   (From Chemical Abstracts 61:2470, 1964)

 The Pb content in blood was determined colorimet-
 rically, using dithizone, or by polarography.
 For the colorimetric determination, the material
 was either wet- or dry-ashed.  The method was
 applied to 3 samples, one containing a physio-
 logical amount of Pb, the 2nd 70 mg%  and the
 3rd 143 mg%.   Statistical evaluation of the re-
 sults indicated that dry-ashing yields  compara-
 tively the smallest errors over a wide range of
 concentrations; besides, this method was the most
 convenient one.  Direct polarographic determina-
 tion gives results with large errors and is not
 applicable for low,  such as physiological, Pb
 contents in blood.   (From authors' English summary)

 Small amounts  of Pb  in polyvinyl  chloride food con-
 tainers and polyvinyl chloride pipes for municipal
water supplies could be determined by spectro-
 graphic X-ray fluorescence while optical emission
 spectroscopy was used for qualitative analysis.
 According to legislation adopted in January 1963,
 plastics containing Cu, Pb, Cd, and Sn based
 stabilizers are not permitted to come in contact
 with food,  and in plastic water pipes, the Pb
 content may not exceed 0.015% and that of Cd,
 0.002%.

       ANALYTICAL METHODS FOR DETERMINATION OF
       LEAD.  Archives of Environmental Health
       8:222-31 (Feb.), 1964.
 The collection of biological samples and air
 samples is described.  The need for precuations
 against contamination is emphasized.  The analyt-
 ical laboratory should be removed from production
                 areas and equipped with air-cleaning systems.
                 Production people in work clothes should not be
                 admitted.  The colorimetric, spectrographic and
                 polarographic methods for the determination of
                 Pb are discussed in detail,  and their applicabil-
                 ity,  reliability, advantages and disadvantages
                 are pointed out.  The colorimetric dithizone
                 method is the method of choice; it is economical,
                 requires no unusual equipment, is adequately sen-
                 sitive and possesses good reproducibility and
                 accuracy.  Quantities of 0.5 pg can be detected
                 with a precision of JTQ.5 yg and with some modi-
                 fications as little as 0,2 ±0.1 yg can be
                 determined.
                   The selection of a method will depend upon the
                 equipment available, the training and personal
                 preferences of the investigator and the nature of
                 the problem.  While any of the chemical or instru-
                 mental procedures can be used directly or modified
                 to yield reliable results, the latter are possible
                 only when the investigator has an intimate knowl-
                 edge of all of the problems and difficulties
                 associated with this work.  Continued daily use
                 of a procedure and the proficiency of the analyst
                 are essential for reliable analyses.  For this
                 reason, it is advised that samples be sent to a
                 laboratory in which such work is done regularly,
                 with all necessary precautions against chance
                 errors, rather than doing them on a sporadic
                 basis by different technicians.

                 Since Pb poisoning is associated with porphyrinu-
                 ria,  the determination of porphyrins is  considered
                 as one of the most valuable laboratory findings  in
                 suspected Pb intoxication.  A new sensitive method
                 for the determination of extremely low concentra-
                 tions ofporphyrins is presented.  It is  based on
                 measurements of fluorescence of porphyrin when ab-
                 sorbed on Mg hydroxide.   The procedure for deter-
                 mining urinary coproporphyrins (CP) is given as
                 an illustration.  The CP's are extracted from an
                 acidified sample of 24-hr urine by shaking with
                 ether, then after washing, removed from the ether
                 by extraction with HC1 acid.  If the fluorescence
                 of this acid extract is  too low to be measured,
                 it is treated with NaOH  and Mg sulfate,  and
                 shaken vigorously which causes the immediate pre-
                 cipitation of Mg hydroxide with complete absorp-
                 tion of CP.  Fluorescence must be measured quickly
                 before the suspension settles.  A double extraction
                 is necessary in cases of old urine samples.  The
                 method is adaptable for other kinds of porphyrins
                 in fluids other than urine when the concentration
                 of porphyrin is very low.

Among the known methods for the determination  of
Pb  in blood, the dithizone method,  polarography
and spectrography  require chemicals which  usually
are not completely free of Pb and therefore  may
produce inaccurate results.  No chemicals  are
needed when X-ray  fluorescence is used.  Blood
samples of 10 g each were dried, pressed into
tablets and the Pb content was measured  by X-ray
fluorescence.  The method permits the determina-
tion of as little  as 0.5 ug/10 g blood.  The de-
termination can be completed within 4 hr with  an
actual work expenditure of 35 min,  compared  to
more than a day and 120 min, respectively, for
the dithizone method.

A rapid method for the determination of  poryphyrin
for the regular surveillance of Pb  workers was de-
scribed.  By adding Ehrllch's Reagent to the urine,
the normal yellow-green fluorescence is  extin-
guished and only the red fluorescence of porphy-
rins, which is visible through a red filter, re-
mains.  Instead of the difficultly  procurable
24-hr sample, fresh morning urine is used.   The
method has an accuracy of 10 ug%.

        EXCHANGE.  Analytical Chemistry 36:1793-6
        (Aug.), 1964.
The method described employs the strongly basic
anion exchange resin Dowex 1, X8.  As a medium for
the separation, a mixture consisting of 90% tetra-
hydrofuran and 10% 5 N nitric acid was selected.
From this solution Pb is absorbed much more strong-
ly on the resin than most other elements, so that
an ion exchange separation by column chromatography
by using the mixture as the eluent, is easily pos-
sible.  U, Th, Bi, Tl, the lanthanides from Sm to
 Lu,  Fe, M.g,  Ca,  and other elements pass  quantita-
 tively  into the  eluate, whereas the  rare earth
 elements  La to Nd are  retained  on  the  resin  with
 Pb which  is  subsequently  eluted with  a mixture
 of 80%  tetrahydrofuran  and  20%  2.5 N  nitric  acid.
                The method could be applied to a variety of mate-
                rials,  including foods and body fluids.  (From

                The study of atmospheric radioactivity which was
                initiated by the U.S. Naval Research Laboratory in
                1948 for the detection of nuclear explosions, also
                served to give information on some of the natural
                radioactive components of the atmosphere.  Sampling
                procedures involved rain collection and air-filtra-
                tion techniques, the latter being preferred for
                reasons of convenience,  reliability and simplicity.
                Isotopes separated  from  rain water included 2->-Opb
                which was identified by  measurement of its daugh-
                ter, 210gi.  xhe  air-monitoring  program permitted
                determination  of  the 222Rn  daughters  (214pb and
                214Bi)  and 220Rn  daughters  (212Pb  and 212Bi).  A
                formula for  the  calculation of  214pb  and  212Pb is
                presented.  Data  on the  210pb  content of  air  at
                ground  level have been obtained from  air-filter
                samples collected along  the 80th meridian as  part
                of  a cooperative  program.   Results of these anal-
                yses are  given in the  paper by Patterson  and

 using  chloroform as  the  extractant  at room temper-
 ature.   Three  California waters  were tested:  summer
 brine  from Owens Lake, pH 10.5;  sea water near
 Santa  Catalina,  pH 8.5;  and  fresh water from Lyman
 Creek,  Deep Springs  Valley,  pH 8.5-9.0.  Extracta-
 bility was determined in 100-200-ml samples to
 which  5 x 10~8 g equivalents of  the cation were
 added.   The results  were influenced by pH and sa-
 linity of the  sample and the metal  to be determined.
 Dinaphthizone  was superior in determining trace
 metals in alkaline lake  brines,  while below pH 8
 dithizone was  preferable.   For Pb,  the per cent ex-
 tractability,  valid  to ±20%, with dinaphthizone and
 dithizone, was:  Owens Lake brine, 100, 70; sea
 water, 80, 90; fresh water,  80,  90, respectively.
  Another  set  of  experiments was run  to show  the
 comparative behavior  of  chloroform  solutions  of
 dinaphthizonates  and  dithizonates with various
 coraplexing  agents  or  stripping solutions  (0.1N
 solutions  of ascorbic acid,  H2S04,  HC1, HBr,  KCN
 and N  solutions  of HC1 and HBr) .  The dinaphthi-
 zonates  proved to  be  slightly more  stable than
 the corresponding  dithizonates.  KCN  removed  only
 0-15%  Pb  from  both the chloroform-dinaphthizone
 and -dithizone phase; all  other  stripping agents
 tested  removed 85-100%.
  Experiments  to  determine several  metals with
 dithizone  in a single aliquot were  successful for
 a semiquantitative determination of Zn,  Cu and  Pb
 in sea  water.  At  Pb  concentrations of 0.2 ppb,  a
 1-liter sample was required;  at  the 1-ppb  level,
 200 ml  were sufficient.
  Experiments  were also  performed,  using  dinaphthi-
 zone-chloroform  extractions  as a method of concen-
 trating trace  metals  for cathode-ray  polarography.
 Pb, Cd,  and Zn effected  a  quantitative transfer
 from chloroform  phase  to aqueous phase both with
 dithizone  and  dinaphthizone;  the other metals did
 not effect  such  transfer though  colorimetry indi-
 cated  quantitative transfer.

 Problems of continuous monitoring of  the  latent
 energy of Rn daughter products including  214pb were
 studied using  a continuous moving filter belt and
 a filter with  periodic motion.  Precipitation of
 dispersion phase aerosols on  the continuous filter
 belt combined with effective  control  of the rela-
 tion between the number  of the RaA  and  RaC  a  decays,

 efficient than more complex  operations with

0.68, 0.47;  clover, 0.97, 0.86, 0.75; synthetic
ashed hay, 0.49, 0.47, 0.35.  Finally, different
amounts of trace elements may be retained by the
residual silicic acid; for Pb, these amount to 19%
for dry-ashed grass and to 4% for wet-ashed grass.

The method of electrode preparation was that which
has been used for insulating powders and is based
on mixing pure graphite with the dried blood plas-
ma directly,  or after ignition of a known weight
of the plasma.  The graphite support matrix was
also analyzed separately.  Photoplates were cali-
brated using the  3C+ line in the graphite blank
spectrum and the concentrations of the elements
were estimated by a visual method.  Among the ele-
ments detected, Pb was 0.2 ppm weight.  For the
majority of  elements detected, the results agree
with known data to within a factor of 3.

A spectroscopic method for the determination of
Pb in the air of workrooms and in the atmosphere
was described.  The average square error is ilO.1%
for artificial solutions, ±14.5% for industrial
tests and Il3.5% for atmospheric air.  The sensi-
tivity in the region of normal blackening is
1 x 10"-3 to 5 x 10~^% depending on the type of
photographic plate used.  Analysis of 10 tests re-
quires 8 hr.  The method can be used in sanitary
epidemiological stations which have an ISP-28
spectrograph.  (This is in the "Synopses and Re-

The toxicity of Pb-containing compounds, alloys
or preparations is considerably decreased by add-
ing U salts or Ge oxides in traces during the
manufacture of the Pb compounds.  The additions
effect an accelerated elimination of the formed
Pb phosphate coupled on the red bone marrow and a
prophylaxis against general virulent tumors, in-
hibit the formation of unnatural d-aminocarboxylic
acids and activate the reticuloendothelial system;
a valuable immunity is imparted against Pb intoxi-
cation.  An addition of ^0.008%  (based on the
crude metal weight) Ge iodide or uranyl chloride
to the melt of a Pb alloy or of 0.01-0.02% (based
on the Pb weight) of a U salt or Ge oxide to the
batch in the Pb pigment manufacture is sufficient.

        Gigiena i Sanit. 1951, No. 7:49-50.
TEL penetrates rather rapidly  into the surface
layers of lumber but  prolonged exposure does not
appear to cause penetration beyond 0.5 cm if ap-
plied perpendicularly to the wood grain fibers.
Application along the grain gives 8-10 times deep-
er penetration.  Similar penetration is achieved
by the vapor,  especially at elevated temperature.
Immersion of lumber samples into the fluid may
cause as much  as 98%  by weight retention after 48-
hr exposure.  A 4-6-day exposure to normal out-
door conditions serves to  remove the TEL that  is
retained by previous  applications, but only from
the vapor state; liquid treatment causes greater
retention and  complete "aeration" is impossible.
Treatment with steam  at 100° is effective only
after 4-5 hr treatment.  (From Chemical Abstracts

This review brings the last one, made 4 yr ago,
up-to-date.  It includes new books published,  re-
search progress made, corrosion data, engineering
applications, and technological advancements.
Bonded Pb has been accepted as a practical means
of combining the corrosion resistance of Pb with
the strength of steel.  Pb-covered Cu similarly
couples the electrical conductivity and greater
heat transfer of Cu with the superior corrosion
characteristics of Pb.  New and more reliable
methods of testing sheet Pb linings and Pb welds
for imperfections have been put into practice
along with a nondestructive method for detecting
bond discontinuities in bonded Pb linings.  In-
terest has been reawakened in the use of cage-
type sheet Pb construction and in the combination
of brick and Pb for high temperature, erosion-cor-
rosion service.  Installation of strapped sheet
Pb lining has been speeded up by the perfection of
automatic stud welding.  The invention of an auto-
matic Pb welding machine has contributed to fur-
ther automation in the Pb fabricating industry.
Pb and Pb alloys are playing an important role
in the control of corrosive pollutants, including
acids that would normally waste into streams and
sulfurous gases and mists wasting into the atmos-
phere.  (29 references)

Optimum conditions described for preparing small
amounts of radioactive TEL of known specific radio-
activity were accomplished by direct isotopic ex-
change between TEL and metallic Pb containing
21°Pb (RaD).  Metallic Pb was prepared from an
aqueous solution of Pb nitrate of known concentra-
tion by galvanic displacement with powdered Mg,
the nitrate solution being "tagged" with 210pt, so
that it had a specific activity of 320 counts/
sec/mg Pb when measured under fixed geometric con-
ditions with a Geiger counter having a window of
1.5 mg/cn>2.  The "tagged" Pb (^10 mg) was prepared
directly in a Pyrex tube containing a thin glass
ampul (^16 mg) of purified nonradioactive TEL,
the tube then being sealed off in vacuo.  Just
before the start of the experiment the ampul was
broken by centrifuging.  (From Chemical Abstracts

The oxidation by air of active Pb oxide prepara-
tions obtained from decomposition of white Pb was
studied.  The activity of the samples was increas-
ed greatly by pulverization, having a large effect
for the samples with a rhombic structure, which
was attributed to the increased rate of their poly-
morphic transition.  Such factors as the state of
the surface, the previous history of the sample,
etc, often have a greater effect than does the
crystalline structure of the rate of oxidation.

Noteworthy technical advancements have been made
in the installation of Pb and the author reviews
the research progress, engineering applications,
technological advancements, new patents, and new
publications of the past year.  Physical and chem-
ical properties of  Pb and Pb alloys, particularly
creep characteristics, have been determined.  The
effects of purity and additions of Sb, Sn, Cu, As,
Bi, Zn, Mg, Ca, Te, Tl, and Ag on the creep char-
acteristics of Pb were investigated.  New en-
gineering applications of bonded or clad Pb lin-
ings on steel and Cu are described.   The perform-
ance of Pb equipment in the handling of liquid
alum and other corrosives is covered along with
some applications of Pb in modern architecture
where resistance to atmospheric corrosion is para-
mount.  Pb metallizing as a means of prolonging
the service life of steel equipment exposed to
sulfuric acid is described.  The use of Pb for
radiation protection is compared with other possi-
ble shielding materials.  The technique of using
a cartridge powered stud driver for anchoring
sheet Pb and steel strapping to steel or concrete
vessels has been put to practical use in the field
resulting in substantially reduced sheet Pb lining
erection cost.  Corrosion performance and other
characteristics of Pb-Sn alloy coated strip steel
are described along with several patents facili-
tating the manufacture of bonded Pb-lined equip-
ment, bonded Pb covered pipe, and the Pb coating
of ferrous objects.  (35 references)

A study was made to determine which materials
should be used in the construction of a deionized
water cooling system. Deionized water was found to
be very similar to distilled water except for the
organic content, which should have little effect
on the conductivity of water except for the corro-
sion. The methods of corrosion are discussed.
The investigation is a compilation of recommenda-
tions for material for high-purity deionized water
systems as recommended by manufacturers of deioniz-
ers and authoritative texts in the fields of corro-
sion and water systems.  A galvanic series is given
of some of the metals (including Pb) investigated.
It was concluded that the most desirable metal for
this use is Al, at a maximum temperature of 177 C,
and wherever possible the system should be Al-clad.
Glass or plastics are nonmetalllc materials that
are capable of handling  deionized water without
contaminating  it.   (From Nuclear Science Abstracts

 This review, including reactions of Pb(ll) with
1 EDTA and other chelates, based on 21 references,
 is summarized by the author as follows:  There are
 2 general ways to influence stability;  (1)  a
 relatively nonspecific one, and (2)  an increase
 in specificity in favorable cases.  The nonspecific
 effect, found generally in the entropy  of reaction,
 is favored by increasing the  positive charge of
 the metal ion, the negative charge of the ligand
 and the number of chelate rings.  This  effect is
 important in maintaining stability in very dilute
 solutions and for strong binding of the more basic
 metal ions.  The other effect, which is reflected
 generally by enthalpy of reaction, increases with
 electronegativity of the metal and with the
 basicity of the ligand.  It can be made to vary
 considerably by changing both the metal ion and
 the nature of the donor groups of the ligand.
 The attainment of relative specificity, or selec-
 tivity, depends largely on this effect  and on
 steric factors.

 lizer into a nitrocellulose propellant, especially
 suitable for use in rockets and guided  missiles.
 Pb butoxyacetate and Pb salts of 5 other acids
 similarly stabilized the burning rate range.

 A method is given for calculating the activity of
 a long-lived parent from the growth of  a daughter
 with a short 1/2 life.   In this method, the
 daughter activity is plotted vs time on one graph
 and compared with a calculated curve until the
 best fit is found.  In this way, daughter equilib-
 rium activity can be determined from data extend-
 ing over little more than 1/2 life of the daugh-

ter, the moment of separation can be determined,
and the daughter 1/2 life can by approximated by
using a family of curves plotted with 1/2 life as
a parameter.  This method is applied to the growth
of 210Bi in a sample of initially pure 21°Pb.

The synthesis and the properties of methylplumbo-
siloxanes are described.  Hexamethylplumbosilox-
ane, (013)3 SiOPb (CH3)3, is a colorless liquid
of high vapor pressure, unexpected thermal stabil-
ity and high sensitivity to water.  It boils with-
out decomposition at 172° under atmospheric pres-
sure of dry N.  At temperatures >150° the vapor
reacts explosively with 0 under formation of ele-
mentary Pb.  Under normal conditions the compound
is stable against dry air and the influence of
light.   Methylplumbosiloxanes have an extremely
unpleasant odor and are highly toxic because of
their good solubility in organic solvents (and in
the lipoid) and their sensitivity to hydrolysis.

                The consumption of Pb in the US from  1951-61 is
                reviewed.  The use of TEL increased from 127,500-
                166,000 tons, while the use of Pb house paints and
                cable sheathing decreased.  New uses  of Pb in the
                fields of sound and vibration, thermoelectricity,
                piezoelectricity, corrosion, ceramics, pigments
                and paints are discussed.

                The solubility of TEL has been measured to aid in
                the understanding of the aqueous solubility of non-
                electrolytes.  Results are reported that indicate
                the magnitude of the solubility of TEL in water
                saturated with air.  Two techniques,  1 for the
                separation of TEL from small volumes  of air and 1
                for its separation from small volumes of water were
                developed.
                   In  the technique described, TEL vapor, water and
                air were equilibrated in all-glass apparatus.  The
                phases were separated,  the  TEL extracted into pen-
                tane, and the pentane analyzed for Pb.   In  the
                separated phases, no decomposition products of TEL
                were  noted.  Between 0.2 and 0.3 mg TEL  saturate
                a  liter of water at 0-38°C.

                After a brief review of the role played by TEL in
                the gasoline industry,  the possible competition by
                other compounds, some of the possible advantages
                and disadvantages involved in the application of
                certain Pb alkyls with higher volatilities  than
                TEL are discussed.  Results of knock  measurements
                on C.F.R. engines and of road tests with various
                gasolines and cars are  described.  With some gaso-
                line-car combinations certain advantages exist
                when  Pb alkyls of a higher volatility than TEL are
                used.   (From authors' summary)

increase of 9 Ib of these inert ingredients resul-
ted in toxicity ratings below that for Pb arsenate
alone.  Increases in toxicity ratings occurred with
increases in the amounts of Celatom MN-39 used.
Decreases in toxicity occurred when Pb arsenate was
used  in combination with Bordeaux mixtures. The
addition of nicotine sulfate to Pb arsenate sprays
showed little increase in toxicity but was much
greater when hydrated lime was added. In combina-
tion  with Bordeaux mixtures toxicity rating was
somewhat less than when hydrated lime alone was
used. There was some evidence that heavy residual
sprays on apples deterred insects from alighting
on such treated fruit. (From authors' summary)

Industrial requirements in the US for Pb in 1963
exceeded the supply from all sources although do-
mestic output of recoverable Pb in ore increased
to 253,400 tons and production of primary refined
and antimonial Pb to 426,200 tons.  Recovery of
secondary Pb from scrap increased 11% above the
1962  level to 493,471 tons, but imports declined
^15%  to 220,400 tons.  Consumption of Pb was 5%
above that of the previous year and amounted to
1,163,400 tons.  Increased use was shown for all
classes except sheet Pb and type metal.  Gasoline
antiknock additives registered a major gain and a
record for this use at 192,800 tons of Pb.  The
two major end product uses of Pb, storage batter-
ies and gasoline additives, combined, represented
54% of the total Pb consumed.  Production of Pb
pigments increased by 4% to 299,400 tons of Pb
content.  The quoted New York price for common Pb
increased from 10-12.50 cents by November 1963.
  In  world mine and smelter production, and con-
sumption, the upward trend also continued during
1963: Mine production was an estimated 2.8 million
short tons and smelter production slightly lower;
free  world consumption was 2.23 million tons of
primary Pb; producer stocks declined from 289,300
tons  at the beginning of the year to 165,600 tons
at yearend.  Japan, r'rance and Italy increased
imports over 1962, while United Kingdom decreased
them  slightly and West Germany did so significant-
ly.   The exports of Belgium, Luxembourg and of the
USSR  increased,  while those of France, West Ger-
many, Canada, and Australia were reduced.
  The program of research and investigation initi-
ated  by the Lead Industries Association and the
American Zinc Institute continued to produce ex-
panded information of the basic characteristics of
Pb and the application of Pb metal and its alloys.
uS patents were issued relating to commercial
techniques for producing a purified metal from the
sulfide, for preparing Pb azide, for producing
battery paste and for a high-temperature treatment
of Pb-Sb alloy.

In collaboration with the National Academy of Sci-
ences-National Research Council's Subcommittee on
Low Level Contamination of Materials  and Reagents,
the authors investigated the y contamination of Pb
and steel.  Eight samples of Pb sheet prepared
from ores from different localities were compared
with 2 reference samples.  The reference samples
gave identical gross spectra which were not sig-
nificantly different from those of Pb samples de-
rived from ores from Missouri, southern Illinois,
Mexico and Australia, estimated to have <2 nCi
  Opb/kg, while 4 of the commercial samples, de-
rived from ores from Nebraska, Peru,  Utah and Can-
ada, showed ^-^Pb contamination ranging from 40-
10 nCi/kg.  In steel, contamination by    Ru was
found which was ^2 orders of magnitude lower than
that of 210Pb in Pb ore.
  As discussed by Rutherford et al (1930), Ra
present in the Pb ore will remain.  Due to decay
of the isotope, old Pb is usually much less active
than new Pb; However, since clean commercial Pb is
available, its use for low-level shielding materi-
al seems to be more economical.

A corroded white-metal lip plug from  Guerrero was
shown by wet-chemical and spectrographlc analyses
to have originally contained over 99% Pb.  After
reviewing 16th-century eyewitness accounts, lin-
guistic evidence, the mineral resources of Mexico,
the technological problems involved in the primi-
tive extraction of Pb from its most common ore,
galena, and the few early Pb artifacts reported
from Mexico, the authors believe that the smelting
of Pb ore and use of metallic Pb were known before
the arrival of the Spaniards and that there is no
valid reason to doubt that this object was made
before the Conquest.

that of L-cysteine.  Under the experimental con-
ditions, L-cysteine and D-penicillamine gave sta-
ble 1:1 and 2:1 complexes with Mn, Fe, Co, Ni, Zn,
Hg and Pb.  The spreading factor between the sta-
bility constants K^ and K2 was small, except with
Pb.  The stability constants (Kj_, K2 and 82) were
calculated on a computer (ZEBRA) with a least-
squares method.  N-acetyl-D-penicillamine also
gave stable 2:1 complexes.  As the calculated
spreading factor is small and K2 > K]_, only 82 is
reliable; therefore, the l:l-complex can exist
only in a small concentration range.
  The order of stability constants of the com-
plexes formed by metals with L-cysteine was: Hg
> Pb > Ni > Zn > Co11 > Fe11 > Mn11; with D-peni-
cillamine: Hg11 > Pb > Ni > Zn > Co11 > Fe11 >
Mn11; with N-acetyl-D-penicillamine: Hg11 > Pb >
Cd > Zn > Ni % Co*1 > Fe11 > Mn.  With each metal
studied the stability constant of the complex of
D-penicillamine was larger than that of L-cyste-
ine; the stability constant of N-acetyl-jj-penicil-
lamine was much smaller.  (From authors' summary)

in 30% yield - though the reaction did not always
occur - from triphenylleadlithium and p-iodo-N,N-

be prepared only by coupling p-lithio-N-lithio-N-

Acid-dissociation constants of DL-methionine, S-
methyl-L-cysteine, DL-ethionlne, L-cysteine, and
DL-penicillamine and the chelate-stability con-
stants with a number of heavy metals, among them
bivalent Pb, are reported for 25° and 0.10M ionic
strength.
  The finding that Pb (II) and Hg (II) form 1:1
chelates of exceptional stability, with penicilla-
mine, shows why the ligand is effective as an an-
tidote for Pb and Hg poisoning.  In these chelates
the ligand binds 3 of 4 coordinating positions to
form a stable soluble metal complex which stays in
solution over the entire range studied (pH 2-11).
                         8:202-12  (Feb.),  1964.
                 After a brief  discussion  of  the mining,  smelting
                 and  refining of Pb,  the consumption of Pb in 1962
                 is reviewed by first enumerating the variety of
                 products in the manufacture  of  which it  is used.
                 The  industries which employ  Pb  include the follow-
                 ing:  storage battery,  petroleum,  cable,  construc-
                 tion,  paint (and  color manufacture),  ceramic,  am-
                 munition,  printing,  railroad, automobile; other
                 uses  are as insecticide,  solders,  coatings for
                 metals,  stabilizer  for plastics,  radiation shield-
                 ing,  for the control of noise and  vibration.  The
                 consumption of Pb in 1962 totaled  >1,075,000 tons
                 and  has averaged  a  little <1,100,000 tons/yr in
                 the  past 10 yr.

                                           SUBJECT  INDEX
           The word "effect" (of lead) has been quitted in most of the entries, unless required
      for clarity.  Subheadings under names of systems and organs refer, unless otherwise indica-
      ted, to findings in clinically established poisoning in man (adult) from repeated exposure
      to inorganic lead (Pb).   Cases of poisoning are listed, with mention of the main subject of
      the published study, under "Lead poisoning," "Tetraethyllead poisoning," etc.   For areas in
      which large numbers of investigations have been published, such as prophyrin metabolism,
      effectiveness of chelating agents, and certain target systems,  appropriate cross references
      are indicated.  From 1950 through 1964, intensive studies on chelating agents  have appeared;
      these are indicated by specific agent rather than "Treatment."   Those that are listed under
      the latter indicate references stating only that the agent had  been used.  "Exposure" in
      subentries indicates findings of functional or metabolic tests  performed to establish the
      degree of exposure to Pb and does not necessarily involve poisoning.  "Population" refers
      to studies using groups of subjects with no unusual exposure to Pb or its compounds;  i.e.,
      urban or area studies.  Since laboratory tests on men and animals under conditions of
      unusual exposure or overt poisoning generally include control values, inclusion of such
      information is understood, and not stated as "vs. normal," unless this is specifically
      emphasized.  Abbreviations and chemical symbols are used in subentries; e.g.,  UK for  United
      Kingdom.  Other abbreviations, apart from those listed under Abbreviations and Symbols, are
      given in this index.
