ABOUT NTIS
As a cornerstone of the technological publishing structure in
the United States, the National Technical Information Service
(NTIS) is a key participant in the development of advanced
information products and services for the achievement of U.S.
productivity and industrial innovation goals in the 1980's.
NTIS, an agency of the U.S. Department of Commerce, is the
central source for the public sale of U.S. Government-sponsored
research, development, and engineering reports, and for sales
of foreign technical reports and other analyses prepared by
national and local government agencies and their contractors
or grantees.
And, it is the central source for:
federally generated machine processable data files
and software;
licensing U.S. Government-owned patents.
NTIS manages the:
Center for the Utilization of Federal Technology
(CUFT), which aterts U.S. industry to specially select-
ed technology having immediate practical value;
Federal Software Exchange Center, for the exchange
of computer software among Federal agencies, with
public availability through NTIS.
Consequently, NTIS is one of the world's leading processors
of specialty information.
The NTIS information collection is approaching two million
titles, several hundred thousand of which contain foreign tech-
nology or foreign marketing information. All are permanently
available for sale, either directly from 80,000 titles in shelf
stock or from microform master copies of documents that are
less in demand. Annually, NTIS supplies its customers with
more than six million documents and microforms, shipping
about 24,000 information items daily.
Full summaries of current U.S. and foreign research reports
and other specialized information, in hundreds of subject cat-
egories, are published regularly by NTIS in a wide variety of
newsletters, journals, and indexes, and in a variety of sub-
scription formats for other Federal agencies. The complete
texts of the technical reports cited are sold in paper and
microform.
Some 70,000 new technical reports of completed research
are added annually to the NTIS Bibliographic Data Base. Any-
one seeking the latest technical reports or wanting to compile
unique subject groups of abstracts may search the NTIS Bibli-
ographic Data Base online using the services of vendors or
organizations that maintain the NTIS data base for public use.
The whole data base in machine readable form may be leased
directly from NTIS.
The more timely documents in the NTIS collection are selected
by category and sold as paperbound Published Searches,
covering some 3,000 topical subject areas.
Customers with well defined continuing interests may sub-
scribe to a standing order microfiche service (SRIM) which
enables them to automatically receive the full texts of only
those documents relating to their individual requirements.
NTIS sells its technical information products and services
under the provisions of Title 15 of the U.S. Code (1151-7). The
law established a clearinghouse for scientific, technical, and
engineering information within the Department of Commerce
and directed that it be self-supporting.
NTIS, therefore, is a unique Government agency supported
by its customers. All costs, such as salaries, manufacturing,
information acquisition, marketing and postage, are paid from
sales income; not from tax-supported congressional appro-
priations, certain developmental programs excepted.

In Section 169A of the Clean Air Act as amended
August 1977, Congress declared as a national goal
the prevention of any future, and the remedying of any
existing, impairment of visibility in mandatory class I
Federal areas which  impairment results from  man-
made air pollution.' Mandatory class I Federal  areas
are national parks greater in size than 6000 acres, wil-
derness areas greater in size than 5000 acres and
international parks that were in existence on August 7,
1977. The section required the Environmental Protec-
tion Agency (EPA) to promulgate regulations requiring
States to develop programs in  their State Implementa-
tion Plans  (SIPs) providing  for visibility protection in
these areas.  EPA promulgated these regulations on
December 2,1980.

The memorandum discusses the process used to cal-
culate the PQLs for lead and copper. The PQLs for
lead and copper have been calculated from the detec-
tion limits listed in Table 1 and from the results of Per-
formance Evaluations (PE) studies. The data from
Water Supply PE studies No. 12-17 and the low lead
concentration sample from Water Pollution PE study
No. 11 have been used to calculate the PQL for lead.
The data from Water Pollution studies No. 12-16 have
been used to calculate the PQL for copper, since
copper was not included in Water Supply studies until
very recently.

The report summarizes the results of the four year field
measurement and data analysis program of MCCP.
The MCCP is sponsored by the U.S. Environmental
Protection Agency as part of the joint U.S. Forest Serv-
ice-EPA Spruce-Fir Research Cooperative. The objec-
tives of the project have been met and the result is an
assessment of principal atmospheric constituents as
they impact the high elevation forests of the Eastern
U.S. Deposition of SO4(-2), NO3(-), H(+), and
NH(4+) in cloud water represents a significant input to
forest canopies with elevations greater than 1000m.
Cloud water deposition can exceed wet (rain) deposi-
tion and may be the dominant process for input of sul-
fate and nitrate compounds during the growing season
in high elevation forests frequently exposed to clouds.
Cloud water pH concentrations may be as much as
0.6pH units lower than pH in rain. SO(4+) and NO3(-)
concentrations are also higher in cloud water than in
precipitation. Ozone data reveals that significant differ-
ences exist between ozone concentrations at high ele-
vation and low elevation sites. The primary effect of
the difference is to produce higher mean ozone con-
centrations and longer episodes at the higher eleva-
tion sites.

Revised Hazard Ranking System (HRS): Final
Rule.
Environmental Protection Agency, Washington, DC.

9Nov90,352p

The U.S. Environmental Protection Agency (EPA) has
revised the Hazard Ranking System (HRS) in response
to the Superfund Amendments and Reauthorization
Act of 1986 (SARA). The HRS is the scoring system
EPA uses to assess the relative threat associated with
the release or potential release of hazardous sub-
stances from a waste site. The HRS score is the pri-
mary criterion EPA uses to determine whether a site
should be placed on the National Priorities List (NPL).
The NPL identifies sites that warrant further investiga-
tion to determine if they pose risks to public health or
the environment. Sites on the NPL are eligible for long-
term 'remedial action' financed under the Comprehen-
sive Environmental Response, Compensation and Li-
ability Act of 1980 (CERCLA), as amended by SARA.
The revised HRS retains the same cutoff score and
basic approach as the original HRS, while incorporat-
ing SARA requirements as well as improvements iden-
tified as necessary by EPA and the public. The revised
HRS retains the ground water, surface water, and air
pathways drops the direct contact and fire/explosion
pathways, and adds a forth pathway, soil exposure.

Pulmonary function measurements on pre-adolescent
children and indoor air pollution measurements in the
homes of these children are used to illustrate estima-
tion techniques for linear regression models containing
independent variables measured with error. In the data
set, replicate measures of indoor air pollutant concen-
trations provide one method of estimating measure-
ment error variances. Surrogate information in the
form of cigarettes smoked is also available for the pol-
lutant of interest. Several estimation procedures are
presented, and two estimators were combined, one
based on surrogate information and one based on rep-
lication information, using generalized least squares.

Progesterone modulation of pituitary function has
been particularly difficult to define in the past. Proges-
terone responsiveness declines within 8 days in pri-
mary ovine pituitary cultures, and its action was com-
pletely overlooked for several years. By contrast, the
activities of E and inhibin are maintained for 3 or 4
weeks in culture. Ovariectomy obliterates progester-
one responsiveness at the pituitary level in vivo al-
though P can still apparently act at the hypothalamus.
Most studies to date have found minimal effects for P,
but this may be due to problems associated with its
correct analysis in vivo. The authors in vitro data pre-
dict that P plays a major negative role at the pituitary
level on: (1) transcription of the genes encoding the
alpha and FSH(beta) subunits, (2) LHRH binding and
responsiveness, and (3) the length of poly(A) tails on
alpha and LH(beta) mRNAs; it is reasonable to believe
that FSH(beta) mRNA may be shortened also. The

 The course is a four-day lecture course dealing with
 the sources and control methods associated with gas-
 eous air pollutants. The course presents the funda-
 mental concepts of the operation of gaseous emission
 control equipment for stationary sources. The lessons
 include a description  of equipment operation, control
 equipment operating parameters that affect efficiency,
 and examples of equipment types used in selected in-
 dustrial applications. Lecture topics include a discus-
 sion of the principles  of absorption, adsorption, com-
 bustion, and condensation. Problem sessions are held
 in which the student calculates equipment efficiencies
 and determines if equipment design meets minimum
 engineering  specifications. The workbook is to be
 used during  the course offering.  It consists of two
 parts: the first contains a chapter corresponding to
 each of the fourteen lessons, and the second contains
 five sets of problems.

 The report considers  several issues related to the
 preparation of isopleth  maps for the display of spatial
 patterns of wet deposition. The valid sample criteria
 and data completeness rating used in the data  sum-
 marization process are described. The data interpola-
 tion technique, kriging,  is presented and its derivation
 in terms of generalized least squares regression is
 given. Four different annual summaries for pH, sulfate
 concentration, and sulfate deposition in 1986 are pre-
 pared using either  the Unified Deposition Database
 Committee (UDDC) definition of valid sample criteria or
 a relaxed  valid sample criteria and the UDDC data
 completeness rating or a relaxed data completeness
 rating. The kriged estimates for the different annual
 summaries and the differences between these esti-
 mates are contoured. The effects of relaxing the valid
 sample criteria and  data completeness rating are dis-
 cussed.  Conclusions are drawn about network oper-
 ation,  network design and the uncertainty of contour
 maps. It is recommended that in  the case where the
 objective is contour maps to show regional patterns,
 the emphasis in  most  regions needs to be on the
 number of valid samples per site and the regional rep-
 resentativeness of the sites.

The purpose of the EPA Cooperative Agreement was
to evaluate the performance  of POE granular activated
carbon (GAC), and diffused  bubble and bubble place
aeration systems treating a  ground water supply con-
taining radon (35,620 + or -  6,717 pCi/L). The pattern
of loading to the units was designed to simulate daily
demand in a household. Each of the systems was eval-
uated with respect to three primary factors: radon re-
moval efficiency, potential problems, and economics.
The radon removal efficiencies of the POE GAC units
gradually deteriorated over time from 99.7% to 79%
for the GAC without  pretreatment and 99.7% to 85%
for the units preceded by ion exchange. The bubble
plate and diffused bubble POE units were very efficient
(99%) at removing radon from the water. The resil-
ience is primarty due  to the high air to water ratios sup-
plied by the aeration blowers. One  major problem as-
sociated with the aeration techniques is iron oxidation/
precipitation.

conducted by EPA during 1989 and part of 1990. The
major objective was to evaluate the potential of active
subslab depressurization (ASD)  in various  geologic
and climatic regions. The different geographic regions
also  presented  a variety of construction types and
heating,  ventilating,  and  air-conditioning  (HVAC)
system designs that are encountered in radon mitiga-
tion of school buildings. A secondary objective was to
initiate research in difficult-to-mitigate schools. The re-
search led to the following major conclusions on radon
diagnostics and mitigation in schools: (1) Schools have
many physical characteristics that typically make their
mitigation more complex than house mitigation, includ-
ing building size and substructure, subslab barriers.

radon entry routes and confirm information in the build-
ing plans, analysis of the HVAC system and its influ-
ence on pressure differentials and radon levels, and
subslab pressure field extension measurements to de-
termine the potential applicability of ASD. (3) ASD can
be applied successfully in schools where subslab com-

The EPA, Office of Solid Waste, Land Disposal
Branch, must develop technical guidance for permit
writers to implement the 'continuing releases' provi-
sion. Implementation of these requirements will typi-
cally take place in three stages: (1) determining wheth-
er there is a release at a facility that warrants further in-
vestigation; (2) collecting additional information to
define the nature and extent of the release; and (3) se-
lecting and performing the corrective measures. The

The regulatory impact analysis was performed in con-
junction with the development of EPA's proposed rule
to require corrective action for releases from solid
waste management units at hazardous waste treat-
ment, storage, and disposal facilities. The results of
the RIA demonstrate that the proposed corrective
action rule is a 'major1 regulation. Pursuant to the Reg-

Phosphorus is a nonmetallic essential element Al-
though phosphorus occurs naturally in the environ-
ment, most of the phosphorus in the environment re-
sults from its manufacture into one of the three allotro-
pic forms (white, red, or black) or into phosphorus
compounds and during the transport and use of these
compounds. White phosphorus/felt and red phospho-
rus/butyl rubber are irritating to the skin and eyes.
Phosphoric acid, phosphorus pentoxide, and the phos-
phorus chlorides are irritating, in some cases corro-
sive, to the skin, eyes, and mucous membranes. Inha-
lation of these compounds has produced respiratory
tract irritation in mammals. The phosphorus chlorides
have also produced effects on the kidney, liver, and
nervous systems of experimental animals. Phosphine
is highly toxic by the inhalation route of exposure and
has reportedly produced gastrointestinal, cardiopul-
monary, and central nervous system effects in
humans. A definite conclusion regarding the possible
reproductive/teratogenic, mutagenic, or carcinogenic
potential of these compounds cannot be drawn be-
cause of the lack of adequate studies.

The report describes the analytical efforts for the de-
termination of polybrominated dioxins (PBDDs) and
furans (PBDFs) in human adipose tissues. Data on the
precision and accuracy of the method for three tetra-
through hexabrominated dioxins and three tetra-
through hexabrominated furans (specific 2,3,7,8-sub-
stituted isomers) were generated from the analysis of
5 unspiked and 10 spiked (5 replicates at 2 spike
levels) adipose tissue samples that were included with
the analysis of the FY 1987 samples. In addition, data
are presented on the results of the analysis of 48 com-
posite samples for the six specific PBDD and PBDF
compounds. The targeted 2,3,7,8-substrtuted PBDDs
and PBDFs were not detected in any of the samples
except those prepared as spiked QC materials. The
detection limits calculated for the tetrabromo con-
geners in the samples ranged from 0.46 to 8.9 pg/g
(lipid basis). The detection limits for the higher bromin-
ated congeners were typically greater than that ob-
served for the tetrabrominated compounds. There is
some evidence for the presence of other brominated
compounds in the adipose tissue samples. Specifical-
ly, responses were noted that correspond to the quali-
tative criteria for polybrominated diphenyl ethers (hexa
through octabromo).

in the document are (1) that the available literature is
extremely poor for use in quantifying the extent of syn-

The hydroxy (RB 19OH) and vinyl sulfone (RB 19-VS)
derivatives of Reactive Blue 19 were identified in a tex-
tile wastewater using a gradient HPLC with a novel
type of electrochemical detection. RB 19-OH could not
be detected in the effluent of the wastewater treat-
ment facility receiving the textile wastewater. RB 19-
VS was present however, in significant amounts. In
laboratory studies, the hydrolysis kinetics of RB 19-VS
were studied in phosphate buffer over a pH range of 4
to 11 and a temperature range of 25 to 85C. "Die half-
life for RB 19-VS at pH=7 at 25C was calculated to be
46 years. Similarly, no loss of RB 19-VS could be de-
tected in a natural water over a 3-week period. The
half-life for the degradation of RB 19-VS in an anaero-
bic sediment-water system, however, was 2.5 days.

pounds was held at the Eighth International Symposi-
um on Chlorinated Dioxins and Related Compounds
(Dioxin '88) in Umea, Sweden, on August 25, 1988.
The session was a follow-up activity sponsored by the
NATO/CCMS Pilot Study on International Information
Exchange on Dioxin and Related Compounds. The
session was intended to present information on future
aspects of dioxin research and regulation in 10 nations
as a means to promote cooperative efforts in the
future. The objectives included the presentation of in-
formation so that research and regulatory planners
and managers are able to identify knowledge voids
and areas of duplication in order to make better in-
formed decisions concerning future activities. The ses-
sion included presentations from: Canada, Denmark,
the Federal Republic of Germany, Italy, the Nether-

An atlas of air quality and deposition data has been
compiled to make air pollution data and information
more accessible to biologists and ecologists working
in western forests. Data from the 1985 National Acid
Precipitation Assessment Program Emission Inventory
are used to characterize emissions of sulphur dioxide
and nitrogen oxides across the West. Maps illustrating
location, type, and magnitude of major point source
emissions together with pie charts of the percent con-
tribution by source category are presented alphabeti-
cally by state. Data from the Environmental Protection
Agency databases AIRS and SAROAD are used to
characterize ambient levels of sulphur dioxide and
ozone for three averaging periods, viz., annual, May
through October or growing season, and monthly.
Data for 20 sulphur dioxide and 70 ozone sites in or
near western forests are presented by state. Biogra-

The  report presents a standard test procedure for
evaluating the performance of leak detection systems
for use in the pipelines associated with underground
storage tanks. The test  procedure  is designed to
evaluate these systems  against  the performance
standards in EPA's underground storage tank regula-
tions (40 CFR Part 280, Subpart D),  which cover an
hourly test, a monthly monitoring test, and a line tight-
ness test The test procedure can be used to evaluate
any type of system that is attached to the pipeline and
monitors or measures either flow rate or changes in
pressure or product volume. The procedure can be
used to evaluate a leak  detection system that can
relate the measured output quantity to leak rate On
terms of gallons per hour) and systems that use an
automatic preset threshold switch. The test procedure
can evaluate systems used to test pressurized pipe-
lines or suction pipelines that are pressurized for the
test The test procedure offers five options for collect-
ing the data required to calculate performance. The re-
sults of the evaluation are reported in  a standard
format on forms provided in the appendices of the
report

 Nine analytical methods covering 54 organic contami-
 nants which may be present in drinking water or drink-
 Big water sources are described in detail. Seven of
 these methods cover compounds designated for regu-
 lation under the Safe Drinking Water Act Amendments
 of 1986. Regulations for this group are in the proposal
 stages  with promulgation scheduled for June 1992.
 The other two methods are for chtorination disinfection
 byproducts and may be regulated as part of EPA's dis-
 infectants and disinfectant byproducts rule scheduled
 for proposal early in 1992. Most of the analytes may be
 classified as non-volatile and three  of the methods
 entail separations by high performance liquid chroma-
 tography. The remainder employ capillary column gas
 chromatography. One of these requires detection of a
 potentially very toxic contaminant 2,3,7,8-tetrachtoro-
 dibenzo-p-dioxin, at the low parts per trillion level. La-
 beled isotopes of this analyte are employed as tracers
 and high resolution mass spectrometry is required for
 detection and unambiguous identification. Three of the
 methods herein  offer  new and  simplified liquid-solid
 extraction  procedures, a  trend which  is likely  to.
 become even more pronounced in the future.

The Illinois Solid Waste Management Act enacted in
September, 1986, established the State's commitment
to address solid waste management needs in Illinois.
The Solid Waste Management Act states: 'It is the pur-
pose of the Act to reduce reliance on land disposal of
solid waste, to encourage and promote alternative
means of managing solid waste,  and to assist local
governments with solid waste planning and manage-
ment In furtherance of those aims, while recognizing
that landfills will continue to be necessary, the Act es-
tablishes the following waste management hierarchy,
in descending order of preference, as State policy: (1)
volume reduction at the source; (2) recycling and
reuse;  (3) combustion with energy recovery; (4) com-
bustion for volume reduction; and (5) disposal in land-
fill facilities'.

Silicone rubber casts of the respiratory tract were used
in morphological studies of the human, baboon, rhesus
monkey,  dog, rabbit guinea pig, rat  hamster,  and
mouse. In the studies, the trachea of  the specimen
was opened by tracheotomy, and silicone rubber (734
RTV) was introduced through the trachea to form na-
sopharyngeal  and tracheobronchial  casts. Measure-
ments were made on the nasal structures, and the
lungs were observed for species variation in branching
pattern and number of lobes per lung. While species
differences in respiratory tract anatomy are known to
exist the study provides a focus for lexicologists when
extrapolating lexicological results from one species to
another.

Airflow patterns in the nasal passages influence the
distribution  of  air-pollutant-induced  lesions  in the
airway mucosa. Little is known about airflow character-
istics of the complex nasopharyngeal  airway  of man
and experimental animals. Airflow characteristics in
the nasopharyngeal airways of an adult male  baboon
(13.9 kg) were investigated with thermistor probes and
the findings compared with flow visualization,  using a
cine-photographic technique. A clear,  acrylic, hollow
cast of a baboon nose was made, and thermistor
probes were inserted to  record air velocity in the cast
lumen using a wind tunnel to propel air through the
cast. An identical cast was studied by passing water
through the cast and using pulses of blue dye to reveal
flow patterns, and then velocities and flow patterns
were determined from cine film with an analytical pro-
jector. Flow rates showed good correlations between
the two methods, whereas cine-photography revealed
areas of turbulence and vortex-like flow. These results
suggest that water flow may provide useful  information
in complex airways  where airflow cannot be deter-
mined.

Deposition data for a potentially susceptible subpopu-
lation such as adolescents are needed, as well as do-
simetry models that can account for variables impor-
tant to a subpopulation. Since the nose acts as the first
line of defense against inhaled airborne contaminants,
the nasal structure of a number of  Fischer-344 male
rats of different age groups was investigated  in the
study. Replica casts of nasal-pharyngeal airways were
made by injecting silicone rubber through the trachea,
and sections in anterior-posterior positions were made
for morphometric  study. Comparison between the
measured cross-sectional areas of the adult rat (body
weight 167.2g and 365.8g) and the adolescent rat
(body weight 12.1, 20.8, 38.7, 65.9,  and 96.8 g) nasal
airways showed a large number of similarities and dis-
similarities. In the groups studied, the cartilage of the
septum decreased as the age increased. The frontal
nasal duct that enters the anterior part of the middle
meatus grew as the age increased. In young noses,
the sphenoidal recesses formed gradually. The eth-
moidal and maxilloturbinates developed as a function
of age.

microwave radiation. Regions of intense energy ab-
sorption are generally thought to be of little conse-
quence when predicting thermal effects of microwave
irradiation because it is presumed that heat transfer via
the circulatory system promptly redistributes localized
heat to equilibrate tissue temperature within the body.
Experiments on anesthetized, male Long-Evans rats
(200-260 g) irradiated for 10 or 16 min with 2,450, 700,
or 360 MHz radiation at SARs of 2 W/kg, 6 W/kg, or 10
W/kg indicated that postirradiation localized tempera-
tures in regions previously shown to exhibit high SARs
were appreciably above temperatures at body sites
with lower SARs. The postirradiation temperatures in
the rectum and tail were significantly higher in rats irra-
diated at 360 MHz and higher in the tail at 2,450 MHz
than temperatures resulting from exposure to 700
MHz. The effect was found for whole-body-averages
SARs as low as 6 W/kg at 360 MHz and 10 W/g at

A leak in a geomembrane lined impoundment or land-
fill has a characteristic electrical response. The author
simulated the waste material, the liner, and the soil
under the liner by infinite horizontal layers and express
the secondary potential for a leak in the geomembrane
liner in terms of a three-layer medium Green's function
and in the unknown current density distribution at the
leak. The area of the leak is sufficiently smallfor the
leak current density to be essentially uniform. The
author added the primary potential associated with a
leak-free liner to the secondary potential to form an in-
tegral equation and derive a general expression for the
current density at the boundary between the waste
material and the liner. From the expression for the cur-
rent density, The author determined the current flow
through the leak and the amplitude of the leak anomaly
response. Multiple circular leaks in the thin resistive
liner are included in the analysis. (Copyright (c) 1988

The validity of a risk assessment can be no better than
that of the exposure assessment upon which it is
based. The general paucity of relevant exposure data,
combined with the limited appreciation by most risk as-
sessors of the critical dimensions and metrics of expo-
sure, often leads to an pverreliance on exposure
models of questionable validity. The problems of iden-
tifying and interpreting relevant metrics of exposure for
epidemiologic studies and risk assessments are illus-
trated through the presentation of three case studies.
The first examines the effects of ozone on respiratory
mechanical function and demonstrates that the appro-
priate averaging time is > or = 6 hr, rather than 1 hr,
as is implied by the current ambient air quality stand-
ard. The second case study examines the effects of
sulfur oxides and particulate matter in ambient air on
morbidity and mortality. It indicates that the effects are
most closely associated with the acidity of the aerosol,
providing a basis for an index of exposure more rele-
vant than those currently used, i.e., sulfur dioxide and
nonspecific gravimetric mass concentration of particu-
late matter. The third case study examines the effects
of lead on blood pressure. It shows that blood lead in
concentrations below 35 microgram/dL correlates
with blood pressure in both humans and animals inde-
pendently of other known casual factors for blood
pressure elevation. It also examines the variable rela-
tions between levels of lead in blood and in environ-
mental media to illustrate the potential problems which
can arise from the use of biological markers, such as
lead in blood, as indices of exposure.

Several conditions complicate the comparison of con-
trol and exposed groups in tumorigenicity experiments.
Time to onset is not observable, tumor types vary in
their lethality, and risk of death from non-tumor causes
can be quite different in the control and exposed
groups. Two tests are commonly used for comparing
control and exposed groups in such experiments, one
of which assumes non-lethality of tumors and one of
which assumes rapid lethality. When the risks of death
from non-tumor causes in the groups differ, both tests
are biased for tumors of intermediate lethality and can
give very different indications about the tumorigenicity
of the compound under test. A method is presented
here to resolve some of the confusion that can arise in
such cases, using an incomplete data analogue of a
cause-pf-death specific test for situations where the
cause is not available, and examples are presented to
illustrate its use. (Copyright (c) 1988 Royal Statistical

Nitrofen and enthylenethiourea (ETU), agents known
to prenatally induce hydronephrosis in rats, were as-
sessed for their effects on postnatal renal functional
maturation. Both were given by gavage to pregnant
Sprague-Dawley rats on Gestation Day 11. Nitrofen
was given at concentrations of 50 or 100 mg/kg, and
ETU at 20, 40, or 60 mg/kg. Renal function was exam-
ined in the offspring from birth until after weaning, the
period of renal functional maturation in the rat. Maxi-
mal urine concentrating ability was measured after
DDAVP (desmopressin acetate, a vasopressin analog)
challenge or water deprivation. Proximal tubule trans-
port was measured in rEnal cortical slices. Various uri-
nary parameters were measured. Both prenatal nitro-
fen and ETU exposure caused a large number of neon-
atal deaths at the high dose, and hydronephrosis was
observed. The severity of the lesion increased with
age. Hydronephrptic animals were deficient in urine
concentrating ability, which became more pronounced
after weaning. A few other urinary parameters were al-
tered, but cortical function appeared to be unaffected.

The onset of peripheral sympathetic neuronal function
is thought to provide trophic regulatory signals for de-
velopment of adrenergic target tissues. In the current
study, the effects on lung development of neonaatal
sympathectomy with 6-hydroxydopamine were exam-
ined. The completeness of the lesion and effective-
ness in reducing sympathetic input to the tissue were
confirmed by direct measurement of norepinephrine
levels and turnover. Despite the denervation, no evi-
dence of beta-receptor up-regulation was found; in
fact, receptor binding sites tended to be reduced
throughout development. The cyclic AMP response to
isoproterenol challenge was initially suppressed in the
lesioned animals, but became supersensitive even in
the face of reduced receptor binding capabilities. Evi-
dence was also obtained for ontogenetic abnormalities
in the omithine decarboxylase/polyamine system,
which is partially controlled by beta-adrenergic input
and which regulates macromolecule synthesis in repli-
cating and differentiating cells. Eventually, the alter-
ations were reflected in aberrant developmental pat-
terns of DNA, RNA and protein in the lung. These re-
sults indicate that sympathetic neurons influence the
biochemical development of the lung and may serve to
program permanently the relationships among recep-
tor sites, receptor coupling to cellular function, and
control of cell maturation.

The tail-flick response of adult male CD-1 mice was
used to assess the analgesic properties of restraint
alone and in combination with morphine during the di-
urnal and nocturnal periods. Mice were restrained in
conical metal devices that allowed a change in posi-
tion from supine to prone but not from front to back.
Restraint induced an analgesia equipotent to a 2.5
mg/kg dose of morphine within 0.5 hr of its initiation.
Although habituation occurred over the restraint period
a pronounced analgesia was still evident at the end of
the 3-hr test period. The habituation to restraint-in-
duced analgesia was more rapid at night. Although the
basal tail-flick latency to thermal stimulation was de-
creased during the nocturnal period the time of day did
not alter the degree of analgesia induced by either re-
straint or morphine. Morphine induced a dose and
time-dependent analgesia during both the diurnal and
nocturnal periods and this analgesia was potentiated
by restraint stress only during the nocturnal period.

Substances known or suspected to cause subtle or
transient anatomical alterations in renal development
were administered prenatally or neonatally to rats in
order to determine whether they are capable of alter-
ing renal functional development Colchicine alters mi-
totic activity and cytoskeletal structure and is terato-
genic in many species. Since the kidney of the new-
bom rat undergoes extensive cellular proliferation and
nephron differentiation, it is possible that neonatal ad-
ministration of colchine may affect  nephron  develop-
ment  Dinoseb and methyl salicylate have previously
been reported to produce a high incidence of dilated
renal pelvis in the term rat fetus. Colchicine was inject-
ed sc, at 75 micrograms/kg, to Postnatal Day (PD) 1
Sprague-Dawley rats. Dinoseb was administered ip to
pregnant Sprague-Dawley rats on Gestation  Days 10-
12 at doses of 8 or 10.5 mg/kg/day, and methyl salicy-
late was administered ip at doses of 200, 250, or 300
mg/kg/day on Gestation Days 11-12. Renal function
was examined in pups from immediately after birth
through weaning. (Copyright (c) 1988 by the Society of

 A validity test of the micro-forward mutation assay
 using Salmonella  typhimurium strain TM677 was car-
 ried  out using benzene-ethand extracts from airborne
 particulates as test materials. Sensitivity of this assay
 in the presence and absence of S-9 mix was five to ten
 times higher than the pre-incubation method, a modi-
 fied  method of Ames's original method, using Salmo-
 nella typhimurium strains TA98  and  TA100. This
 means that the virtual sensitivity of the micro-forward
 mutation assay is greater by ten times or more than the
 pre-incubation method, because two or more  strains
 are necessary in the latter method. Repeatability of the
 micro-forward mutation assay was nearly same with
 that  of the pre-incubation method. That is, the coeffi-
 cient of variation of mutagenic frequency of the panic-
 ulate extracts was about 10%. This forward mutation
 assay  was applied  to airborne particulates indoors,
 and proved to be able to measure easHy the mutagenic
 activity of the extracts from particulates collected by
 30 cu m-air sampling.  Some indoor pollutants, espe-
 cially ones collected  in a room in which cigarette
 smoking was done, showed higher mutagenic activity
 than that of outdoor sample.

Sixty day old male CD rats were exposed by nose only
to (14)C-methyl bromide (55 ppm) for three minutes.
The data indicated that the liver, lung, and kidney were
the major organs of (14)C deposition immediately fol-
lowing exposure. Up to thirty-two hours following expo-
sure, the major routes of excretion were pulmonary
(14CO2) and renal with approximately 43% and 21%
of the total inhaled radiolabel being eliminated, respec-
tively. In separate experiments, 60 day old CD male
rats were exposed by whole body inhalation for 6
hours/day for 1,5, and 10 days to 30 ppm methyl bro-
mide or control air. Following the 1 day exposure,  glu-
tathione (GSH) reductase activity in the  liver showed
an increase, while GSH S-transferase was significantly
increased. Glucose-6-dehydrogenase (G-6-PDH) was
increased and nonprotein sulfhydryl content was de-
creased in the kidney. After 5 days of exposure, GSH
transferase activity was significantly increased, while
G-6-PDH showed an increase in the lung. GSH reduc-
tase activity had decreased in the liver. After 10 days
of exposure an increase in G-6-PDH activity was  evi-
dent in the lung, and a significant decrease in GSH re-
ductase and GSH S-transferase activities were found
in the liver.

 The reactivities of  a series of molecules in a Michael
 addition reaction are analyzed on the basis of  proper-
 ties expressed in the Laplatian of the charge  density
 distribution. The charge densities of structurally opti-
 mized acrylic acid (AA), methacrylic acid (MAA), acry-
 lonitrile (ACN) and  acrolein (ACR) have been calculat-
 ed by ab-initio quantum mechanical methods with vari-
 ous basis sets. The relative reactivities of the activated
 double  bond in the molecules toward a nucleophilic
 attack, predicted by the values of Laplatian of  the cal-
 culated charge density at the corresponding critical
 point are in accord with experiment The change in
 atomic properties of two reactants, AA and MAA, upon
 the nucleophilic addition of F(sup 1-) are also  derived
 from the Laplatian of the charge density. The changes
 in the properties provide a quantitative description of
 AAF(sup 1-) and MAAF(sup 1-) carbanion formation
 which is related to  the size of the region of charge de-
 pletion  on the attacked atom. (Copyright (c)  1989

The effect of a single i.p. injection of 0, 20, 200, and

of the hepatic drug-metabolizing enzyme system was
measured in the rat by a model substrate assay, em-
ploying lindane (gamma-hexachlorocyclohexane), and
by a battery of in vitro enzyme assays. The data in the
study indicated that carbon tetrachloride had a bipha-
sic influence on the phase I reactions with the lowest
dose inducing a significant increase in enzyme activity
while the highest dose produced significant inhibition.
Significant  CCI4-induced  reductions in  glucuronyl-
transferase and sulfotransferase activities were also
observed while the effect on glutathione-S-transferase
was  ambiguous.   The  in  vivo  and  in vitro assays

The electrostatic interaction is a critical component of
intermolecular interactions  in  biological  processes.
Rapid methods  for the computation and  characteriza-
tion of the molecular electrostatic potential (MEP) that
segment the molecular charge distribution and replace
this continuous  function by  a series of multipole mo-
ments for  each  segment have been described. There
are two sources of error in these techniques: (1) The
truncation of the expansion  after just a few terms,  (2)
The charge in the segmental distribution that is more
distant from the expansion center than the observation
point. In order to expand this range a method is intro-
duced that uses exact techniques to compute the MEP
for the part of the molecular charge distribution de-
scribed by the gaussians on each atom with the small-
est exponential  parameter and uses segmental multi-
pole methods for the remainder of the charge. Using
pyrrole with an STO-3g wave function as an example,
this method significantly improves the potential in the
range 1.4-2.0 A from atoms with only an  increase of
1 % in computational effort needed when compared to
a computation of the exact potential. If other basis sets
are used with more diffuse gaussians the convergence
of the multipole expansion will be at greater distances
from the atoms and this type of correction will be more
important.

 Three different  methods were compared for their effi-
 ciency at detection of adenoviruses. The samples ex-
 amined for viral analysis consisted of concentrates
 prepared from  raw sewage, chosen as being repre-
 sentative of the spectrum of viruses being intestinally
 shed from a large population at any given time. When
 using one single cell line, HEp-2, the overall numbers
 of adenoviruses detected using Cytopathogenicity and
 immunofluorescence were roughly equal.  In-situ hy-
 bridization was  approximately forty percent more sen-
 sitive than either of these other  methods as deter-
 mined by average virus liters for the different samples,
 and also proved to be better by means of a nonpara-
 metric comparison. The 293 cell line was approximate-
 ly five times more sensitive for detecting adenoviruses

Chemicals entering marine waters are incorporated
into distinct compartments and these reservoirs are in
exchange with one another. The chemo-dynamic stor-
age compartments in marine systems include sedi-
ment to the depth of bioturbation (0-50 cm), suspend-
ed sediments, dissolved phases (pore, ventilation and
overlying water), and tissue residues. The key trans-
port processes are particle flux across the sediment-
water interface, vertical mixing within the bioturbation
zone, and dissolved contaminant exchange between
suspended particles or sediment and surrounding sea-
water or interstitial water. The key transport variables
in entrainment are physical shear, bioturbation, and
sediment cohesiveness. Vertical mixing may be mostly
a function of the rate of conveyor-type feeding. Dis-
solved exchange between solid and dissolved phases
is controlled by concentration gradients, partitioning
relationships, organic matter, surface area, and some-
times redox conditions. Irrigated burrow systems ac-
count for most exchange of solutes and deep burial of
newly deposited solids.

Chemical intervention during prenatal or postnatal on-
togeny can result in complex biochemical, morphologi-
cal and behavioral alterations in brain development. As
has been shown at the conference, the knowledge of
specific actions of a given drug/chemical in the adult
can serve as a guide for choosing processes affected
by the same compound administered during develop-
ment. Commonly, however, the neuronal or glial sub-
strates for chemical action in the developing brain are
not known and cannot be easily predicted on the basis
of effects observed in the mature animal. Indeed, there
are a multitude of structurally dissimilar compounds
that affect diverse and unpredictable targets in the de-
veloping brain. The focus of the review is to present an
approach for detecting and characterizing chemically-
altered brain development that can be used regardless
of the information available on the chemical in ques-
tion. (Copyright (c) 1989 by Intox Press, Inc.)

In the presence of S9, the mutagenic potency of 2-
aminpanthracene was similar among the three buffers;
likewise, the mutagenic potency of environmental to-
bacco smoke was also similar among the buffers. In
the absence of S9, the 0.15 M buffer resulted in re-
duced mutagenic potencies of 1 -nitropyrene and disel
exhaust compared to the respective potencies of
these agents with the other two buffers. The cell con-
centrations had little effect on the mutagenic poten-
cies of these agents with or without S9. In the absence
of S9, the 0.15 M buffer was highly cytotoxic, resulting
in 23% survival of the control cells after 90 min of incu-
bation, compared to 89 and 35% survival, respectively,
for 0.015 M and VBM. In the presence of S9, the 0.15

The author studied urine cotinine excretion in 27 chil-
dren who attended a research day care center to de-
termine the extent of correlation between urine cotin-
ine-creatinine ratios (CCR) and intensity of nicotine ex-
posure in the home. Average nicotine levels in home
air were determined by active air sampling during the
evening and night hours on two consecutive days.
Urine samples for cotinine and creatinine determina-
tions were collected before, during, and after the two
sampling periods. In addition, four sequential weekly
urine samples for CCR were obtained from study chil-
dren to determine the extent to which single determi-
nations of CCR were representative for individual chil-
dren. Fifteen children resided in homes with smokers
and 12 did not. Urine CCR consistently distinguished
most exposed and unexposed children. However,
three exposed children had urine CCR's which clus-
tered routinely around the borderline CCR (30 ng/mg
cotinine-creatinine) used to distinguish exposed and
unexposed children. In children exposed to environ-
mental tobacco smoke in the home, there was a signif-
icant correlation between average home air nicotine
levels and the logarighm of urine CCR the mornings
following the home air monitoring periods (r = 0.57; p
= 0.004). In study children, urine CCR's were remark-
able stable over the one month observation period.
Rank correlation coefficients for sequential weekly de-
terminations of CCR were consistently greater than r
= 0.89; p< 0.001.

Adult female rats were orally dosed with 1 /5 the LD50
of either an initiator of carcinogens (1,2-dibromo-3-
chloropropane (DBCP)), promoters or putative promot-
ers of Carcinogenesis (hexachlorobenzene, alpha-hex-
achlorocyclohexane, kepone and toxaphene) or non-
carcinogens (coumaphos, EDTA, caprolactam, 8-hy-
droxyquinoline, titanium(IV)oxide, sodium diethyidithio-
carbamate (DEDTC), and sucrose) at 21 and 4 hours
before sacrifice. The initiator and promoters selected
in the study were all of the halogenated hydrocarbon
class. DBCP caused a large degree of hepatic DNA
damage and an increase in hepatic ODC activity. At
doses ranging between 1 /5 to 3/5 the LD50, all four
promoters or putative promoters induced rat hepatic
ODC activity. The seven noncarcinogens produced
several biochemical effects at doses of 1 /5 the LD50:
serum alaine aminotransferase (SGPT) increases (ca-
prolactam and DEDTC), decreased hepatic cytoch-
rome P-450 (sucrose and DEDTC) and increased he-
patic ODC (8-hydroxyquinoline and DEDTC). None of
the seven noncarcinogens caused hepatic DNA
damage or coordinate induction of hepatic ODC and
cytochrome P-450.

The environmental release of genetically altered
microorganisms has prompted the investigation of
their potential health effects by employing in vivo
rodent models. Even though the direct health effects
are addressed, the investigation primarily examines
some potential indirect health effects. The model was
used previously to examine several mutant Pseudo-
monas species isolated from a commerical product for
polychlorinated biphenyl (PCS) biodegradation. Indi-
rect effects examined include the colonization of the
gastrointestinal tract, competition with the resident mi-
crobiota, and translocation of the dosed microorga-
nisms to other organs . Ampicillin treatment of the
mice enhanced the survival of the PCB degraders. Am-
picillin treatment also had a significant effect on the mi-
crobiota in the intestine, by selecting primarily for the
facultative species. The alteration of the lactose-fer-
menting enterobacteria, obligately anaerobic predomi-
nantly Gram-negative rods, and total aerobic and an-
aerobic populations were monitored in the presence
and absence of the PCB-degrading pseudpmonau.
Depending on the dosed strain, a significant difference
in the monitored populations as compared to control
animals was observed. (Copyright (c) 1989 by the So-

 A surrogate tracheobronchial (TB) system, capable of
 simulating the in vivo atmosphere (such as  tempera-
 ture and relative humidity) in a physiologically realistic
 manner, is reported here. This surrogate Toxicology
 Branch system is a tubular,  multicomponent physical
 model where the average Reynolds number value for
 the airflow within  each respective compartment or
 section, equals the value within the  corresponding
 bronchial airway generation of  Weibel's Model A net-
 work. Mass-transport  phenomenon (such as in vivo
 water flow through a TB wall and its membrane, and
 subsequent water evaporation into inhaled air) was
 simulated using this sytem.  Detailed information re-
 garding localized air temperature and water vapor con-
 centration patterns for the steady flow rate of 13.5 I/
 min is reported in the work. The  impact of the  laryngeal
 simulator was studied, and average values of Nusselt
 and Sherwood numbers for each bronchial generation
 are reported. These values were lowest downstream
 from the laryngeal simulator. The in vitro temperature
 and water vapor concentration patterns and transfer
 coefficients can be used in a future quantitative analy-
 sis of the dynamic behavior and deposition rates of hy-
 groscopic aerosol particles. (Copyright (c)  1989 Else-

 Methods to measure damage to sensory systems fol-
 lowing toxicant exposure vary from  rapid and subjec-
 tive tests (e.g., pinna reflex) to time-consuming and ob-
 jective tests (e.g., psychophysical tests). Reflex modifi-
 cation of the startle response represents an alternative
 technique in the assessment of sensory function. Ad-
 vantages of this procedure include: no prior training re-
 quirements, rapid and  objective measurement of sen-
 sory thresholds,  ability to differentiate sensory from
 non-sensory damage,  and potential for predictive va-
 lidity. This procedure has also been shown to  be sensi-
 tive to a variety of neurotoxic compounds. Future re-
search should concentrate on demonstrating the re-
search potential of this technique for use in neurotoxi-
cology.

An ambient air sampling study was conducted around
a municipal waste combustor with a primary goal being
to develop procedures to evaluate the emissions of or-
ganic mutagens resulting from incomplete combustion
of municipal waste. The products of incomplete com-
bustion from incineration include complex mixtures of
organics, particularly polycyclfc aromatic compounds,
which are present after atmospheric dilution and cool-
ing in emissions as semi-volatile  or particle bound or-
ganic compounds. Combustion emissions are general-
ly recognized as a potential cancer risk since they con-
tain many carcinogenic  and mutagenic polycyclic aro-
matic hydrocarbons. Analyzing such  a complex mix-
ture for the presence of even a few selected chemicals
is difficult and provides risk information on only a frac-
tion of the chemicals present Bioassay methods, how-
ever, may be directly applied to evaluate the mutagen-
ic and carcinogenic activity of the complex organics
from combustion emissions. The Salmonella (Ames)
assay was used to determine the mutagenicity associ-
ated with  particles from ambient air collected near a
municipal waste combustor. Dose-response data was
generated, and mutagenicity concentrations were cal-
culated to demonstrate the utility of bioassay  in as-
sessing emissions from municipal waste combustion.

 Air pollution epidemiology since the 1950s has been
 able to demonstrate that increases in daily mortality in
 London, England, were associated with elevated con-
 centrations of index air pollutants, such as  British
 Smoke (BS) and sulfur dioxide (SO2). In the work, the
 authors reanalyze that portion  of the 1958-1972 winter
 mortality-pollution  record for  which daily  direct acid
 aerosol measurements were made at a central site in
 London (St. Bartholomew's Medical College). The pur-
 poses of these  exploratory analyses are to examine
 the dataset for indications of  a relationship between
 acid aerosol pollution and human mortality and to com-
 pare any noted associations with those for other pollu-
 tion variables. It is found that the log of acid aerosol
 concentrations is more  strongly associated with raw
 total mortality in bivariate analyses than  is BS or SO2,
 despite the tact  that acid data are available from only
 one central site (versus seven disperse sites  for  BS
 and SO2). The logarithmic nature of the exposure side
 of the H2SO4-mortality relationship implies a satura-
 tion model of pollution effects,  possibly due to muitiday
 pollution harvesting influences on a susceptible sub-
 population. The apparent advantage of H2SO4 over
 BS in predicting total raw mortality is consistent with
 the hypothesis that it is the portion of paniculate mass
 of greater hearth significance  and may also allow  the
 development  of London mortality results which  are
 more easily transferable to other environments than is
 the case for existing BS results.

Several past studies of the historical London air pollu-
tion record have reported an association between daily
mortality and British Smoke levels. However, the pollu-
tion index does  not give direct information on particu-
late mass or its chemical composition. A more specific
paniculate matter index, aerosol  acidity, was meas-
ured at  a site in central London, and  daily data are
availble  for the  period 1963-1972. British Smoke and
SO2 were also measured at the same site. Also, mete-
orological parameters were routinely measured at a
nearby British Meteorological Office. Thus, daily fluctu-
ation of the acidic aerosols was characterized in terms
of other environmental parameters. Each of the other
parameters analyzed seems necessary, but not suffi-
cient to  explain  a high level of acidic aerosol. Overall,
about half of the variance of log-transformed daily fluc-
tuations of acidic aerosols can be  explained by a com-
bination  of  parameters including  SO2  and British
Smoke  concentrations,  temperature,  ventilation by
wind,  and humidity. The rest of the variance cannot be
explained by the parameters included in the analysis.
Potential factors responsible for the unique variance
would be variations in the availability of  basic gases to
cause neutralization and variation in the availability of
catalytic metal salts. Because the acidic aerosol has a
unique component of variation, it may  be possible to
distinguish health effects due to this specific pollutant
from other available pollution indices or environmental
factors.

 Micronuclei induction in bone marrow erythrqcytes of
 mice is a commonly used index of clastogenicity. How-
 ever, micronuclei could also originate from intact lag-
 ging chromosomes. We have  used  antikinetochore
 antibodies to distinguish kinetochore  containing mi-
 cronuclei from those originating from acentric chromo-
 somal fragments. This provides a method to identify
 the agents capable of inducing lagging chromosomes,
 by inference aneuploidy in an in vivo system. The tech-
 nique was evaluated using a known clastogen, ionizing
 radiation; and a known aneuploidy inducing agent, vin-
 cristine sulfate. The frequence of total micronucleated
 erythrocytes increased with the dose with both agents.
 Micronuclei induced by  x-irradiation were predomi-
 nantly negative for kinetochores while the majority of
 the  micronuclei resulting from the effect of Vincristine
 contained kinetochore. Staining for kinetochores pro-
 vide a qualitative method  to identify environmental
 agents capable of inducing aneuploidy.

Fumigant applicators who, 6 weeks to 3 months earli-
er, were exposed to phosphine, a common grain fumi-
gant, or to phosphine and other pesticides had signifi-
cantly increased stable chromosome rearrangements,
primarily translocations in G-banded lymphocytes.
Less stable aberrations including chromatid deletions
and gaps were significantly increased only during the
application season, but not at this later time point
During fumigant application, measured exposure to
phosphine exceeds accepted national standards.
Since phosphine is also used as a dopant in the micro-
chip industry and is generated in waste treatment, the
possibility of more widespread exposure and long term
health sequelae must be considered. (Copyright (c)

A series of field studies involving repetitive functional
measurements in relatively small populations of
healthy children and adults engaged in normal outdoor
activities has shown that significant decrements in res-
piratory function are associated with exposures to
ozone (O3) at concentrations below the national ambi-
ent air quality standard. The ability to detect such ef-
fects can be attributed, at least in part, to the study
design criteria used, which emphasized maximization
of signal-to-noise ratios. Locations were selected to
ensure relatively high exposures to relatively uniformly
distributed secondary pollutants, with minimal expo-
sure to local sources of primary pollutants. Populations
were selected that would be engaged in active recrea-
tion out of doors. Populations of healthy persons were
used to minimize variability in baseline function. It was
found that the magnitude of the OS-associated decre-
ments in respiratory function was dependent on the
variability in sensitivity to O3 among the population, the
minute ventilation during outdoor activity, and the dura-
tion of the outdoor exposure.

Ambient monitoring of acid aerosols in four U.S. cities
and in a rural region of southern Ontario clearly show
distinct periods of strong acidity. Measurements made
in Kingston, TN, and Steubenville, OH, resulted in 24-
hr H(+) ion concentrations exceeding 100 nmole/cu
m more than 10 times during summer months. Periods
of elevated acidic aerosols occur less frequently in
winter months. The H(+) determined during episodic
conditions in southern Ontario indicates that respirato-
ry tract deposition can exceed the effects level report-
ed in clinical studies. Observed 12-hr (H+) concentra-
tions exceeded 550 nmole/cu m (approximately 27 mi-
crogram/cu m H2SO4). The maximum estimated 1-hr
concentration exceeded 1500 nmole/cu m for H(+)
ions. At these concentrations, an active child might re-
ceive more than 2000 nmole of H(+) ion in 12 hr and
in excess of 900 nmole during the hour when H2SO4
exceeded 50 microgram/cu m.

In a sample of 149 adult nonsmokers recruited in New
Mexico in 1986, the authors assessed the reliability of
questionnaire responses on lifetime exposure to to-
bacco smoke in the home. They also compared urinary
colinine levels with questionnaire reports of environ-
mental tobacco smoke exposure during the previous
24 hours. The agreement of responses obtained on
two occasions within six months was high for parental
smoking during childhood: 94% for the mother and
93% for the father. For the amounts smoked by the
mother and the father during the subject's childhood,
the agreement between the two interviews was moder-
ate: 52% and 39%, respectively. For the number of
hours per day that each parent smoked in the home
during the subject's childhood, the Spearman correla-
tion coefficients also indicated only moderate reliability
(r = 0.18 for maternal smoking and r = 0.54 for pater-
nal smoking). For each set of interviews, responses
concerning recent tobacco smoke exposure and uri-
nary cotinine levels were correlated to only a modest
degree. The authors conclude that adults can reliably
report whether household members smoked during
their childhood, but information on quantitative as-
pects of smoking is reported less reliably. (Copyright

As part of the on-going Harvard Study on the Health
Effects of Sulfur Dioxide and Respirable Particulates,
the authors have developed monitoring equipment for
acidic particles that can be used in multiple field set-
tings. Preliminary data suggest that these strong acid
aerosol measurements may correlate with respiratory
symptoms more closely than similar measurements of
paniculate matter less than 15 micro m in size. These
results have led to the beginning of a U.S.-Canadian
cooperative study to assess the chronic effects of acid
aerosols on the health of North American children.
Communities are being selected on the basis of antici-
pated levels of H2S04 in ambient air along with pre-
dicted levels of ozone and nitrates. Each community
will undergo a 1-year period of every other day, 24-hr
monitoring with newly developed monitoring equip-
ment that will allow for quantification of H ion concen-
trations, as well as for specific measures of ozone and
acid fractions. At the end of the 1-year period, while
measurements are still being made, approximately 600
children aged 7 to 11 in each of up to 24 communities
will be assessed with standardized questionnaires
completed by parents, and pulmonary function will be
measured in the children while in school. By estimating
chronic exposure from the year-long measurement of
acid aerosols and consideration of specific criteria for
selecting communities to study; the authors hope to
minimize potential confounding to allow us to assess
the chronic impact of strong acid in the atmosphere on
the respiratory health of these children.

The formamidine pesticide amitraz (AMZ) produces
many behavioral and physiological changes in rats. To
explore possible neurochemical mechanisms for the
behavioral effects of AMZ, the dose effect and time
course of AMZ on motor activity, monoamine pxidase
(MAO) and acetylcholinesterase (AChE) activity were
examined. For motor activity studies, male Long-Evans
hooded rats were tested in photocell activity measure-
ment devices. AMZ produced dose-related decreases
in motor activity of rats allowed free access to food
and rats maintained at a stable body weight through
food restriction. Lowest effective doses of AMZ tested
were 1-3 mg/kg, administered 20 min before testing.
AMZ appeared to be about 3 times more potent in
food-restricted rats, indicating that amount of body fat
may play a significant role in the pharmacokinetics of
AMZ. Motor activity returned to control levels over 4-5
days after dosing with 100-200 mg/kg AMZ, whereas
recovery was evident the day after administration of
low doses (1-30 mg/kg). Inhibition of MAO was meas-
ured in whole brain of rats sacrificed at various times
after dosing with AMZ. Only doses greater than or
equal to 100 mg/kg AMZ inhibited MAO, which was
measurable within 2 hr after dosing and lasted up to 7
days. (Copyright (c) 1989 by the Society of Toxicol-

tally harmful environmental exposures are of great in-
terest and possibly of great value. Such markers are in
two discrete classes, those quantitatively related to ex-
posure itself, reflecting the magnitude of such expo-
sures or of the body burden of the pollutants, and
those markers which reflect the biological response to
such exposures. This paper suggests guidelines for
the appropriate use of cross-sectional, retrospective,
and prospective designs in epidemiologic investiga-
tions of markers of exposure and disease. Also pre-
sented are suggestions for the application of sensitivi-
ty, specificity, reliability, and acceptability in marker
studies since the effectiveness of any marker will ulti-
mately be judged on these characteristics.

A general mathematical model describing the motion
of particles in aerosol centrifuges has been developed.
It has been validated by comparisons of theoretically
predicted calibration sites with experimental data from
tests sizing aerosols in instruments of three different
spiral duct configurations. By accurately simulating
factors which influence centrifuge performance, the
model enhances the versatility of existing instruments
and promotes CAD (computer aided design) and CAM
(computer aided manufacture) of new units. The model
will permit more accurate aerodynamic classifications
of airborne particles. Therefore, more precise determi-
nations of deposition sites of inhaled aerosols within
the lung will be possible, since such locations are pri-
marily functions on the dynamic characteristics of
motion. U.S. EPA risk assessment protocols of pollut-
ant aerosols will thereby be improved. (Copyright (c)

Three experiments examined developmental changes
in the reversal of a learned discrimination in an olfacto-
ry conditioning paradigm. Preweanling rats were ex-
posed to an odor (CS+) paired with footshock, and a
different odor (CS-) that was explicitly unpaired with
footshock. They were then immediately tested for their
preference between the CS+ and CS- odors. In Ex-
periment 1, animals trained at 12- or 18-days of age
showed equivalent conditioned aversions to the CS+.
When the significance of the cues was reversed the
younger animals showed rapid reversal teaming, i.e.
their aversion to the original CS+ was displaced by an
aversion to the original CS-. But the 18-day-old ani-
mals were slower to acquire reversal of the discrimina-
tion. Experiment 2 showed a similar pattern of results
when animals received separate preference tests in-
volving the CS+ vs a novel odor, or the CS- vs a novel
odor. In Experiment 3, intact 18-day-old rats and 18-
day-olds with damage to the septum and fomix
showed equivalent conditioned aversions to the CS+.

In vitro exposure of chick forebrain tissue to 50-MHz
radiofrequency (RF) radiation, amplitude modulated
(AM) at 16 Hz, would enhance the efflux of calcium
ions only within two power density ranges: one span-
ning from 1.44 to 1.67 mW/sq cm, and the other in-
cluding 3.64 mW/sq cm. No-effect results occurred at
0.37, 0.72, 2.17 and 4.32 mW/sq cm. These results
were replicated and extended by testing another set of
power densities, which included the range of the previ-
ous study. Forebrain tissue from 1-7 day-old chickens
were labeled in vitro with radioactive calcium ions (30
min, at 37 C), rinsed, placed in a physiological salt so-
lution and exposed for 20 min to 50-MHz radiation, AM
at 16 Hz, in a TEM cell maintained at 37 C. The solu-
tion was then assayed for radioactive calcium activity.
A power density series was tested. Enhanced efflux of
calcium ions was found at 1.75, 3.85, 5.57, 6.82, 7.65,
7.77, and 8.82 mW/sq cm; no change was observed at
0.75, 2.30, 4.50, 5.85, 7.08, 8.19, 8.66, 10.6, and 14.7
mW/sq cm. Power density is converted to specific ab-
sorption rate by 0.36 mW/kg/mW/sq cm; a value
much too low for generalized heating of the sample to
be the underlying cause of the response. A hypotheti-
cal mechanism is proposed involving dynamical sys-
tems that may account for the power density depend-
ency as well as for part of the frequency dependency
observed for both modulated RF radiation and for ELF
fields. (Copyright (c) 1989 Alan R. Liss, Inc.)

In order to assess adverse health effects caused by an
event resulting in high levels of cadmium in drinking
water, rats received CdCI2 by gavage or in drinking
water for 1 or 10 days. The reported acute oral LD50 in
rats (225 mg/kg - Kotsonis and Klaassen, 1977) was
confirmed. Male and female Sprague-Dawtey derived
rats received CdCI2 by gavage at doses of 25, 51,107
and 225 mg/kg body weight for 10 consecutive days.
Other rats received CdCI2 solutions at concentrations
of 0.014, 0.14 and 0.29 mg/ml. There were naive and
vehicle controls. Compound related adverse effects
were noted on body weights (decrease) and BUN. His-
topathologic lesions, apparently compound related,
were observed in the testis, kidney and liver of ga-
vaged animals but not in the animals that received
CdCI2 in the drinking water.

Angiotensin converting enzyme (ACE) catalyzes the
conversion of angiotensin I to angiotensin II (a potent
vasopressor) and plays an important role in homeosta-
sis of blood pressure. ACE has been shown to be as-
sociated primarily with the luminal surfaces of lung
vascular endothelial cells making it a possible target
for phosgene and ozone. Sixty-day-old male Sprague
Dawley rats were exposed to 0.5 ppm phosgene, 1.0
ppm ozone, or air for 4 hr. Rats were sacrificed imme-
diately and 24 hr. postexposure. ACE activity was
measured in lung, lavage fluid, lavage fluid cells, and
serum. Both phosgene and ozone exposed rats
showed no changes in ACE activity in either lavage
fluid or serum compared to air controls. Whole lung
ACE activity was significantly higher immediately and
marginally higher 24 hours postexposure to phosgene
with increases of 34% and 16%, respectively. Phos-
gene exposed rats also showed a significant increase
in ACE activity in the lavage fluid cells. These in-
creases were 50% and 54% above controls at 0 and
24 hr postexposure, respectively. The cell type most
likely affected was the alveolar macrophage. No signif-
icant effects were seen following ozone exposure.

The potentiation of CCI4 toxicity by pre-exposure to
chlordecone (CD) is well established. Chlordecone-in-
duced metabolism of CCI4 and suppressed hepatocel-
lular repair have been offered as possible mechanisms
for this potentiation. The present study was initiated to
determine if metabolism and disposition of (14)CCI4 is
altered in the PH rat, and if this is a contributing factor
to the reported protective effect afforded by the PH
procedure. The rats were challenged with a single
dose of CCI4 (100 microliters/kg, ip) containing 20
micro Ci(14)CCI4. Lipid peroxidation and serum
enzyme activities (aspartate aminotransferase (AST)
and alanine aminotransferase (ALT)) were measured
as indices of toxicity. (Copyright (c) 1989 VCH Publish-

Previous work has shown that dietary exposure of rats
to non-toxic levels of chlordecone (10 parts per mil-
lion) for 15 days and a subsequent intraperitoneal in-
jection of a low, non-toxic dose of CCI4 results in a dra-
matic potentiation of hepatotoxicity and lethality great-
er than that observed after a high dose (2.5 ml/kg
body weight) of CCI4 alone. This remarkable amplifica-
tion of CCI4 toxicity is due to the failure of the hepato-
cellular regenerative and hepatolobular repair mecha-
nisms. Polyamines are known to be important for liver
regeneration and the progressive phase of hepatotoxi-
city and lethality observed after the combination treat-
ment might be related to the extent of suppressed po-
lyamine metabolism in the liver. In the study polya-
mines and related enzymes were estimated in the
livers of rats treated with either chlordecone and CCI4
or CCI4 alone.

A predictive aerosol deposition model, which has been
validated by comparison with experimental data from
adult test subjects, is used to study particle deposition
patterns within the developing human lung. Here, an
age-dependent lung morphology is presented in which
the growth of bronchial airway dimensions is described
by the measurements of Phalen et al. (1985), and the
number and sizes of pulmonary airways are derived
i Dunnill (1962). Total tracheobronchial, and pul-
from I
monary deposition fractions are calculated for different
breathing patterns, from sedentary to maximal activity,
and particle sizes, ranging over three orders of magni-
tude. The influences of human subject age and physi-
cal activity levels upon regional aerosol deposition
within the developing lung are complex; systematic
patterns, however, can be identified which are consist-
ent with the effects of linear airway dimensions and
particle flow characteristics upon effective particle
deposition mechanisms.

Higher cardiovascular mortality has been associated in
a single epidemiological study with higher levels of
barium in drinking water. The purpose of the study was
to determine whether drinking water barium at levels
found in some U.S. communities alters the known risk
factors for cardiovascular disease. Eleven healthy men
completed a 10-week dose-response protocol in which
diet was controlled (600 mg cholesterol; 40% fat, 40%
carbohydrate, 20% protein; sodium and potassium
controlled at the subject's pre-protocol estimated
intake). Other aspects of the subjects' lifestyles known
to affect cardiac risk factors were controlled, and the
barium content (as barium chloride) of the drinking
water (1.5 L/day) was varied from 0 (first 2 weeks), to 5
ppm (next 4 weeks), to 10 ppm (last 4 weeks). Multiple
blood and urine samples, morning and evening blood
pressure measurements, and 48-hr electrocardiogra-
phic monitoring were performed at each dose of
barium. There were no changes in morning or evening
systolic or diastolic blood pressures, plasma cholester-
ol or lipoprotein or apolipoprotein levels, serum potas-
sium or glucose levels, or urine catecholamine levels.
There were no arrythmias related to barium exposure
detected on continuous electrocardiograph^ monitor-
ing. A trend was seen toward increased total serum
calcium levels with exposure to barium, which was of
borderline statistical significance and of doubtful clini-
cal significance. In summary, drinking water barium at
levels of 5 and 10 ppm did not appear to affect any of
the known modifiable cardiovascular risk factors.

The neurotoxic effects of long term, low-level expo-
sure to the commercially available insecticide, Fenth-
ion, were examined in the present study. Young adult,
male long-Evans rats were dermally exposed to Fenth-
ion (25 mg/kg, 3X wk.) and sampled after 2 and 10
month exposure to assess neurotoxic damage in the
hippocampus using morphological and biochemical
endpoints. Cytopathology, consisting of gliosis and
swollen and necrotic neurons, occurred in the dentate
gyrus (DG) and hilus (CA4) as early as 2 mo. exposure.
Acetylcholinesterase (AChE) staining of brain tissues
taken at the time was severely reduced in the septal
nuclei, the DG molecular layer, the hilus, and the
hippocampus proper. After 10 mo. exposure to Fenth-
ion, cellular necrosis and gliosis progressed to the CA3
regions and occasionally involved the CA2. Radiomet-
ric assays of AChE activity in the hippocampus indicat-
ed a 65% and 85% depression after 2 and 10 mo. ex-
posure, respectively. Quinuclidinyl benzilate (QNB)
binding for the hippocampal muscarinic receptor was
reduced by 6% and 15% after 2 and 10 mo. exposure.
A separate group of older (12 mo.) rats were exposed
to the same dosing regimen of Fenthion and examined
for neuropathic damage after 2 mo. and 10 mo. expo-
sure. Aged animals exposed for only 2 mo. expressed
severe hippocampal degeneration in a pattern similar
to that seen in the young adult after 10 mo. exposure
(viz., DG, CA4, CA3). (Copyright (c) 1990 by Academic

Female mice of the AKR/J(AK) strain were fed a con-
trol diet (Purina chow) or a lipotrope-supplemented
diet (Purina chow plus 2% D.L.-methionine and 1%
choline chloride) beginning at one week after weaning.
Mice of this inbred strain spontaneously develop
thymic lymphoma, with close to 100% mortality ex-
pected by 12-13 months of age. Two separate experi-
ments were carried out with 50 mice per group in one,
and 40 mice per group in the other. The slopes of the
survival curves for the animals in the control group and
supplemented group of mice diverged after the ani-
mals reached 6.5 months of age. In both experiments,
20% of the mice receiving supplemented diet were still
alive at one year, while 3% in one experiment and 8%
in the other experiment survived in the control groups.
Each experiment was terminated when the animals
reached 13 months of age. At that time the survival
rate of the controls was 2% and 4%, and survival in
the groups of mice receiving supplemented diet was
14% and 18%. Necropsy revealed that the animals in
both groups had advanced malginant lymphoma. The
results demonstrate that intake of a chow diet that is
supplemented with moderate quantities of methionine
and choline results in enhanced survival of spontane-
ously leukemic AK mice, in comparison with animals of
this strain fed the same diet without supplements of
choline and methionine.

flammation and damage in the lung. The contribution
of alveolar macrqphages to this process is not well un-
derstood. In  addition, ozone may cause  more exten-
sive cellular  changes than those currently measured
by  enzymatic or immunological  methods.  Therefore
the authors have used molecular techniques to meas-
ure changes in the total spectrum of alveolar macro-
phage proteins in humans exposed to ozone. In the
study, eight human volunteers were exposed once to
0.4 ppm and once to filtered air for 2 hours with inter-
mittent exercise.  Eighteen hours later bronchoalveolar
lavage was performed  and alveolar macrophages
were  isolated. Changes  in  proteins made by these
cells after air or ozone exposure were analyzed by high
resolution two-dimensional  gel electrophoresis, using
computerized densitometry to quantify changes in indi-
vidual proteins.  Of the nearly 900  proteins analyzed,
23 (2.6%) were synthesized at  a significantly  in-
creased  rate following  ozone  exposure  while  71
(8.1%) were synthesized at a significantly reduced
rate.  These  results indicate  that exposure of humans
to ozone causes extensive changes in the spectrum of
macrophage proteins being produced.  Quantitative
two-dimensional gel electrophoresis is a highly sensi-
tive technique which may reveal much more informa-
tion about the in vivo effects of a  pollutant than has
previously been available.  Furthermore  the ability to
survey large numbers of macrophage proteins after ex-
posure to various inhaled pollutants may allow a better
understanding of the mechanisms of action of these
agents, as well as provide new biomarkers of pollutant
exposure.

The effect of ambient temperature T(sub a) and run-
ning wheel activity (RWA) on fetal outcome was stud-
ied in CD-1  mice. Pregnant mice were allowed  to be
active in a running wheel at various T(sub a)'s (26,  30,
32, 34 or 36C) for 100 mins a day. The dams  were
killed near term, and various maternal and fetal meas-
urements made. Mean deep body  temperature T(sub
b)  in pregnant dams while  running  (measured  using
radio-telethermometers implanted in the abdomen)
was raised to 39.5 C at T(sub a)=36. Bred mice con-
tinued to increase their RWA, pregnant or not but
pregnant mice exercise toss from  mid-pregnancy on.
RWA up to 1 km/hr had  no  effect on maternal weight
gain,  litter size, number of live fetuses,  fetal  body
weight and  fetal relative brain weight.  However,  in-
creasing T(sub a) was effective in decreasing maternal
weight gain and fetal body weight, and increasing fetal
relative brain weight. Even though T(sub b) can be in-
creased significantly by either RWA or T(sub a), the in-
crease caused by RWA appears to have  no significant
influence on the outcome of pregnancy. At levels in
this study, T(sub b) per se does not appear to be the

Cardiopulmonacy responses to histamine and metha-
choline bronchochallenge were examined and com-
pared  in  unanesthetized  spontaneously  breathing
guinea pigs. All animals had surgically implanted intra-
pleural catheters and some had arterial or right heart
catheters as well. Animals were placed in plethysmo-
graphs, and exposed to ascending doses of aerosol-
ized agonists. The provocative dose, i.e. the dose that
caused a clear bronchospastic response, was defined
as the concentration that increased intrapleural pres-
sure to at least 20 cm H2O. Results showed that bron-
chospasm was further characterized by decreases in
dynamic lung compliance and arterial PO2 and an in-
crease in airway resistance. The accumulation  of
trapped gas in the lung after challenge, measured in
the excised collapsed lung, con-elated with the in-
crease in intrapleural pressure and with the fall in lung
compliance. Male guinea  pigs between 3  and 15
weeks of age did not vary in sensitivity to histamine.
Methacholine and histamine were equipotent and pro-
duced similar responses. Tachyphylaxis was not dem-
onstrated for either compound. In addition, the provoc-
ative dose for the drugs  remained stable on a day to
day basis. These results offer insight into the nature of
the bronchospastic response in guinea pigs and pro-
vide new data on response methacholine. (Copyright

 Seventeen-day-old  rat  pups received  intraoral infu-
 sions of two novel flavors, coffee (.625% w/v Sanka,
 decaffeinated) and saccharin (.5% w/v), of which one
 (CS+) was paired with  a .75% body weight, i.p. injec-
 tion of 0.4 M LiCI, and the other (CS-) was presented
 alone. On the following day, two more infusion tests
 were conducted to determine intake of each flavor.
 Intake of the CS-t- flavor was markedly suppressed
 relative to that of the CS- flavor, although the magni-
 tude of this effect depended on which flavor was des-
 ignated CS+ and on the order in which CS+ and CS-
 were presented on the test day. These results indicate
 that  preweanling rats  are capable of discriminative
 taste aversion learning.  The simple conditioning proce-
 dure should provide a useful method for studying the
 sensory development of the gustatory system and/or
 the  developmental  psychobiology of learning  and
 memory. (Copyright (c) 1990 Psychonomic Society,

 Assessment measures used in developmental neuro-
 toxicology are  reviewed  for  their comparability in
 humans and laboratory animals, and their ability to
 detect comparable  adverse effects across species.
 Compounds  used  for these  comparisons  include:
 abuse  substances,  anticonvulsant  drugs, ethanol,
methylmercury, lead, PCBs, and ionizing radiation. At
the level of functional category (sensory, motivational,
cognitive and motor function, and social  behavior),
close agreement was found across species for all neu-
rotoxic agents reviewed, particularly at high exposure
levels.  This was  true even though the specific end-
points  used  to assess these  functions often varied
substantially across species. In addition, it was found
that: (1) the Developmental Neurotoxicology Test Bat-
tery presented at the Workshop would have identified
the hazard to humans of exposure to the above com-
pounds, although it may have underestimated  human
risk in some cases; (2) assessment of developmental
neurotoxicity should involve evaluation of all catego-
ries of function; (3) for most compounds reviewed, the
neurotoxic effects of prenatal exposure cannot be at-
tributed to maternal toxicity, and exposure at or just
below the threshold for such toxicity is an appropriate
upper  level for develop-mental neurotoxicity testing;
(4) maternal exposure during the  postnatal  period
poses  a number  of serious methodological problems;
and (5) animal  studies would better parallel  human
studies if more emphasis was placed on assessment
during  development.

 Pattern-onset visual evoked potentials were  elicited
from humans by sinusoidal gratings of 0.5, 1, 2 and 4
 cpd (cycles/degree) following adaptation  to a blank
field or one of the gratings. The wave forms recorded
 after blank field adaptation showed  an early positive
 component, PO, which decreased in amplitude with
 spatial frequency, whereas the immediately succeed-
 ing  negative component, N1, increased in amplitude
 with spatial frequency. PO and  N1  components of
 comparable size were recorded at 1 cpd. Stationary
 pattern adaptation to a grating of the same spatial fre-
 quency as the test grating significantly reduced N1 am-
 plitude at 4,2 and 1 cpd. The N1 component elicited at
 4 cpd was attenuated in log-linear fashion as the spa-
 tial frequency of the adaptation grating increased. PO,
 on the other hand, was unaffected by stationary pat-
 tern adaptation at all combinations of test and adapt-
 ing  spatial  frequencies  , although PO amplitude  is
 known to be attenuated by adaptafon to a drifting grat-
 ing. Since N1, but not PO, was significantly attenuated
 following  adaptation and testing at 1 cpd,  it was con-
 cluded that the neurons generating these components
 are functionally distinct. The use of a common adapta-
 tion grating discounted the possibility that N1, but not
 PO, was affected due to a difference in the rates of ret-
 inal image  modulation caused by  eye  movements
 made  while viewing adaptation gratings of different
 spatial frequencies. The neurons generating N1 were
 adapted at  a lower rate of retinal image  modulation
than that apparently required for adaptation of the neu-
 rons generating  PO, which suggests a difference be-
tween these neurons in the rate of stimulus modulation
 necessary for activation. (Copyright (c) 1990 Elsevier

A two day technical workshop was convened in No-
vember, 1986 to discuss analytical approaches for de-
termining trace amounts of cotinine in human body
fluids resulting from passive exposure to environmen-
tal tobacco smoke (ETS). The workshop, jointly spon-
sored by the US EPA and CDC, was attended by invit-
ed scientists with expertise in cotinine analytical meth-
odology and/or conduct of human monitoring studies
related to ETS. The workshop format included techni-
cal presentations, separate panel discussions on chro-
matography and immunoassay analytical approaches,
and group discussions related to the quality assur-
ance/quality control (QA/QC) aspects of future moni-
toring programs. The report presents a consensus of
opinion on general issues before the workshop panel
participants and also a detailed comparison of several
analytical approaches being utilized by the various rep-
resented laboratories. The salient features of the chro-
matography and immunoassay analytical methods are
discussed separately.

Awake Fischer-344 rats were exposed to O3 and re-
sponse was evaluated before, during and after the ex-
posure using a protocol similar to that used in many
human studies. To enhance test sensitivity, COZ was
periodically added to the O3-air exposure mixture. Fif-
teen min. alternate periods of filtered air or 2, 4, 6, or
8% CO2 were used to stimulate ventilation and to in-
crease pollutant uptake, much like exercise in con-
trolled human exposure studies. Ventilation and
breathing mechanics were evaluated at 0.0,0.12,0.25,
0.5 and 1.0 ppm O3, while ventilation and blood pres-
sure, blood gases and the electrocardiogram were
evaluated at 0.0 and 1.0 ppm O3. Control experiments
provided data on the effect of ozone exposure to 0.5
ppm O3 without added CO2 challenge. Results indicat-
ed that CO2 enhanced the detection of O3 effects at
concentrations lower than 0.5 ppm O3. As O3 concen-
tration increased, the magnitude of ventilatory re-
sponse (decrease in tidal volume and increase in fre-
quency of breathing) was greater and the onset of
effect was progressively sooner. Breathing mechanics
were not affected by O3 exposure except for an in-
crease in expiratory flow rates near the end of the tidal
breath. (Copyright (c) 1990 by John Wiley and Sons,

Recent clinical evidence indicates that in humans
subchronic exposure to Pb during development can
result in decreased developmental scores and behav-
ioral alterations in the absence of overt neurotoxicity.
The mechanism(s) by which Pb induces such alter-
ations is unknown. Conceivably, the central nervous
system (CNS) may be especially sensitive to Pb. On
the other hand, deleterious effects of Pb may not be
mediated directly by Pb itself. For example, perturba-
tion of CNS function may be a manifestation of essen-
tial/trace mineral deficiencies resulting from Pb-in-
duced impairment of mineral availability and/or in-
creased sensitivity of the CNS to Pb intoxication in the
absence of adequate levels of essential minerals. Fo-
cusing on the role of essential/trace mineral alter-
ations is reasonable since the behavioral sequelae of
neonatal Pb exposure often mimic those accompany-
ing specific trace mineral deficiencies during this
period of development. The current status of knowl-
edge of the interactions of lead and essential elements
is reviewed. (Copyright (c) 1990 by Intox Press, Inc.)

The acaricide chlordimeform has been reported to
have adverse effects in mammals that may be mediat-
ed by an interaction with alpha-adrenergic receptors.
Since the hormonal signals involved in the regulation
of reproductive function are themselves under hypo-
thalamic adrenergic control, the study was designed to
investigate the effects of acute exposure to this com-
pound on the hypothalamic-pituitary-testicular axis.
Male rats given two intraperitoneal injections of chlor-
dimeform-HC) {20 or 50mg/kg) spaced 12 nrs apart
showed 24 hr declines in serum gonadotropins at
50mg/kg that were paralleled by a drop in testoster-
one. These changes returned to control levels by 96
hrs. Thyroid stimulating hormone exhibited a dose-re-
sponse decline that was accompanied by a similar de-
crease in serum thyroid hormone levels. The stimulat-
ed secretion in vitro of gonadotropin-releasing hor-
mone from hypothalamic explants was suppressed at
the higher dose, while LH release from pituitary frag-
ments in culture was unaffected. (Copyright (c) 1990

The seizure-inducing properties of two pyrethroidP
were assessed by pentylenetetrazol (PTZ) seizure
models (repeated ip, sprathreshold ip, and iv), and
electrical kindling of the amygdala. The efficacy of po
versus ip routes of deltamethrin administration was
compared using iv-PTZ administration and tests of lo-
comotor activity in a figure-eight maze. The Type I pyr-
ethroid, cismethrin (8 or 15 mg/kg), and the Type II
pyrethroid, deltamethrin (6 or 10 mg/kg), were admin-
istered daily, 2 hours prior to electrical kindling stimula-
tion. Both pyrethroids facilitated amygdala kindling to a
minimal but equivalent degree, but only at dosages
that also evoked strong behavioral signs of toxicity.
Cismethrin (15 mg/kg, po) produced a 17% reduction
in the threshold dosage of ip-PTZ required to induce a
seizure, while delaying the onset of generalized sei-
zure activity. Deltamethrin (10 mg/kg, po) failed to
alter threshold or latency to seizure onset, but did in-
crease seizure duration. No differences were revealed
between po (0,10,15 mg/kg) or ip (0,1,10 mg/kg) ad-
ministered deltamethrin on thresholds, seizure dura-
tions, latencies to myoclonic jerks, or generalized sei-
zure activity following iv-PTZ. (Copyright (c) 1990 by

Twelve compounds representative of diverse classes
of chemicals were evaluated for their cytotoxicity and
transforming ability of human skin fibroblasts in vitro in
the presence and absence of human liver S-9 mix. In
the absence of the human liver S-9 mix, only seven of
the twelve compounds were highly cytotoxic in the 0-
100 microgram/ml range and their order of cytotoxicity
was: 2,5-bis(1 -aziridinyl)-3,6-bis(carboethoxyamino)-
1,4-benzoquinone (AZQ) > cis-platin > N, N-bis(2-
chloroethyl)-2-naphthylamine > bis(chloromethyl)-
ether (BCME) > acrylonitrile > styrene oxide > afla-
toxin 81 (AFB1). The other five compounds, aflatoxin
B2 (AFB2), methylmethacrylate, 1-naphthalamine, 2-
naphthylamine, and cyclophosphamide, exhibited less
than 40% inhibition of colony formation even at 100
microgram/ml of the compound (the maximum con-
centration of AFB2 used was 50 microgram/ml due to
its poor solubility). Cytotoxicity was not significantly al-
tered in the presence of human liver S-9 mix except for
AFB1 and styrene oxide treatment. There was a dras-
tic increase in cytotoxicity following treatment with 1
micrpgram/ml or more AFB1 and a significant reduc-
tion in cytotoxicity following treatment with 100 micro-
gram/ml styrene oxide in the presence of S-9 mix. An-
chorage independent growth (Al) of treated cells in
soft agar was used as a biological end point for the ex-
pression of chemical transformation. (Copyright (c)

 Dichkxomethane (DCM) is a widely used industrial sol-
 vent which has been determined to be a carcinogen in
 rats and mice. In vitro and in vivo analyses of chromo-
 some damage induced by this  agent nave provided
 conflicting results. In order to further investigate the
 clastogenic  potential of  DCM in vivo, we analyzed
 SCEs and chromosome aberrations (CAs) in mouse
 bone marrow cells following intraperitoneal exposures.
 DCM failed to increase the frequencies of either SCEs
 or CAs.

 An ab initio STO-5G computational analysis of  the
 electrostatic potentials of four structural analogs of the
 highly     toxic     2,3,7,8-tetrachkxodibenzo-p-dioxin
 (TCDD)   and  four  related  aromatic    systems
 (benzo(a)pyrene, benz(a)anthracene and two isomeric
 benzoftavones) was carried out The systems, to vary-
 ing degrees, induce ary) hydrocarbon hydroxytase ac-
 tivity and are believed to interact with the same cytoso-
 lic receptor in initiating their biochemical  responses. It
 was found that a high degree of activity appears to re-
 quire negative  potentials that are  non-overlapping
 above  all or most of the  lateral regions, with an ob-
 served optimum range of magnitudes. In  systems with
 central oxygens, it is required that the negative oxygen
 potentials be small and weak; however, oxygen nega-
 tive regions in the molecule are not necessary for high
 activity. The observed differences between the poten-
 tial patterns of the four aromatic systems and those of
 TCDD and its active analogs may reflect an inherent
 dissimilarity in the nature of their interactions with the
 cvtosolic receptor.

Ten cohorts of nickel exposed workers which had pre-
viously been studied in terms of total nickel exposure
were updated and re-analyzed to evaluate the cancer
risk from the various chemical forms of nickel to which
they had been exposed. Industrial records were used
to construct occupational histories of individual work-
ers and to derive estimates of exposure to nickel and
its compounds in their working environments. Subse-
quent mortality was then assessed in relation to expo-
sure estimates. The major conclusion from the re-
search is that risk to lung and nasal cancer is related to
more than one form of nickel. Although increased risk
in most workers can be attributed to mixtures of oxidic
and sulfidic nickel, high exposures to nickel oxide in
the absence of nickel subsulfide was also associated
with increased risk. There was also evidence that solu-
ble nickel increases cancer risk.

 Quantitative extrapolation of toxicity data from animals
 to humans will allow more accurate  assessments of
 human health risks. The overall objective of this inves-
 tigation is to provide the tissue sensitivity data neces-
 sary to extrapolate quantitatively the toxic effects of in-
 haled particles from animals to humans. In the initial
 study, cadmium sulfate (CdSO4) toxicity for human
 and Fischer 344 rat nasal turbinate  epithelial  (NTE)
 cells was evaluated in vitro. The studies were unique in
 that both rat and human NTE cells were obtained from
 fresh, normal tissue. Methods were developed for iso-
 lating and  culturing NTE  cells from rat and human
 tissue using identical procedures, and for measuring
 the cellular nudeotides by HPLC. Changes in adeny-
 late energy charge (EC) and nudeotide levels were
 used as toxicity endpoints.  Cellular  Cd levels were
 measured by graphite furnace atomic absorption spec-
 trometry and expressed as microgram Cd/microgram
 DMA. Using these methods, the cellular Cd dose and
 the toxic effect in each cell type were measured and
 compared.

The Wisconsin Heart Health Research Program meas-
ured serum lipids and other clinical parameters among
residents of forty-six neighboring small communities in
central Wisconsin. The purpose of the study was to de-
termine whether distribution of serum lipids, blood
pressure or thyroid hormones differed according to the
Chlorination of the water supply, or to its calcium and
magnesium content (hardness). This report examines
serum lipid levels in relation to the drinking water char-
acteristics Chlorination and hardness. Variables meas-
ured on individuals included age, education level, alco-
hol intake, cigarette smoking, dietary fat and dietary
calcium. An analysis of covariance was used to esti-
mate effects of Chlorination and hardness on each of
the serum lipids, with individual variables included as
covariates. Among females, serum cholesterol  (SC)
levels are significantly higher in chlorinated communi-
ties than in nonchlorinated communities. Community
SC levels are also higher for males in chlorinated com-
munities, on the average, but differences are smaller
and not statistically significant. LDL cholesterol levels
follow a  similar pattern to that for total SC levels,
higher in chlorinated communities for females, but not
different for males. On the other hand, HDL cholester-
ol community means are nearly identical in the chlorin-
ated and  nonchlorinated communities for each sex.

 The  recovery of  3-chloro-4-(dichloromethyl)-5-hy-
 droxy-2(5H)-furanone  (MX) from granular activated
 carbon (GAQ/distilled water by adsorption on XAD-8
 resin was approximately 3-fold greater than on XAD-2
 resin. When chlorine was added at levels ranging from
 0-3 mg/L, the percent of MX recovered by XAD ad-
 sorption decreased as the concentration of chlorine in-
 creased. Using concentrations of MX which allowed
 direct  measurement  of its mutagenicity,  a time-de-
 pendent decrease  in mutagenicity was observed,
 which was enhanced by the presence of chlorine. The
 concentration of MX as determined by UV absorbance
 also decreased in the presence of chlorine, at a rate
 which  increased with increasing chlorine  concentra-
 tion. These  results  suggest  that the  level  of MX
 present  in tap water is dependent  not only on the
 amount of MX produced by the Chlorination of humic
 substances  and other precursors but also on the rate
 of degradation with residual chlorine.

The article discusses an evaluation of the emission of
perchloroethylene (tetrachloroethylene) from  freshly
dry cleaned fabrics using  small environmental test
chambers.  The  temperature dependence of the re-
lease of perchloroethylene was evaluated over a tem-
perature range of 20 to 45 C. A linear relation exists
between the logarithm of perchloroethylene retention
time and the reciprocal of the absolute temperature.
Study results for 100% wool and 55% polyester/45%
wool indicate that 'airing out' freshly dry cleaned fab-
rics at above ambient temperature will increase  the
rate at which perchloroethylene is emitted from  the
fabrics.

dioxin   (PCDD)  and  polychlorinated dibenzofuran
(PCDF) and their precursors in  a laboratory reactor.
Both homogeneous and  heterogeneous  reactions
were studied between 200 and  800 C with HCI, CI2,
and phenol as reactants in a simulated flue gas. Analy-
sis of the reactor effluent showed that homogeneous
phase production of chlorophenols, potential precur-

In 1976, Kilian and Bulow described the association of
B-Glucuronidase with  the genus Escherichia  (97%
positive) and suggested that a  B-Glucuronidase assay
would be a useful identification test. Since that report,
papers  about the  sensitivity  and  specificity of this
enzyme for the  identification of Escherichia coli from
clinical sources, food, seawater,  potable-water sup-
plies,  and various  environmental sources have ap-
peared. A study was undertaken to determine the effi-
cacy and specificity of the defined-substrate technolo-
gy B-glucuronidase (Colilert) assay for the identifica-
tion of this species from fecal  samples. A total of 460
human, 105 cow, and 55 horse E. coli isolates were
tested. Results  showed 95.5% B-Glucuronidase-posi-
tive isolates in 24 h and 99.5%  positive after 28 h of in-
cubation. Only one E. coli isolate was negative. There
were no significant differences in the percentage of B-
Giucuronidase-positive isolates among the human or
animal isolates.  There were no non-E. coli isolates that
were  positive.  All subjects carried B-Glucuronidase-
positive E. coli.  (Copyright (c)  1990 American Society

The article focuses on the results of bench- and pilot-
scale studies of ion exchange processes for radium re-
moval  from groundwater  in Lempnt, III.  Batch and
column studies indicated a very high resin selectivity
for radium compared with common cations. Exhaus-
tion-regeneration studies  with  a  variety of  resins
showed that a standard gel-type strong-acid cation ex-
changer is most suitable for radium removal in cyclic
operation. Because the ion exchange softening proc-
ess, operating to hardness breakthrough (300-360 bed
volumes (BV)), removes radium but does not fully uti-
lize  the  resin  capacity, cyclic  runs were made with
resins exhausted to radium breakthrough (2,500-3,000
BV) and regenerated with sodium and calcium salts.
But because of poor radium regenerability of the ex-
hausted resins, simultaneous breakthrough of  radium
and hardness occurred during the subsequent exhaus-
tion run on the sodium cycle, and high radium leakage
was observed on the calcium cycle. The sodium ion
exchange softening  process  (operated  to hardness
breakthrough without regenerant reuse) continues to
be an  appropriate technology for the  removal  of
radium.

unstressed  by recent transfer,  unaccustomed sur-
roundings or the presence of an observer could move
freely in 16  oxygen concentration gradients within the
limits of 1 and 8.9 mg O2/I. They avoided oxygen con-
centrations  below 4  mg/l most of  the time and pre-
ferred 5 mg/l or higher more than half the time, which
supports the field-derived belief that fish avoid oxygen

A method to determine the mortality effects of a hydro-
phobic chemical on a population is proposed. The eco-
toxicological protocol is based on individual organism
response and is derived from the static theory of 'sur-
vival of the fattest.' This study, focusing on effects of
mortality  and the effects of toxicant stress on popula-
tion succession, examines the static assessment sur-
vival of the fattest in a dynamic population model. A
premise  in this  approach  is that  risk  assessment
should not be  based solely on chemical properties of
the toxicant and that the biology of the exposed orga-
nisms is an important factor in the determination of ef-
fects.

 Simple  assumptions for individual toxic response, ex-
 change of toxicant with environmental  concentrations
 and body composition are used in a model to evaluate
 the effect of lipid variation on toxic response in a sub-
 population of similarly sized  individuals. The model
 represents the internal distribution of a chemical such
 that  more  hydro-phobic  compounds preferentially
 move into body lipid. Thus, for exposures of  equal
 chemical activity, both increasing body fat and greater
 hydrophobicities increase the exposure duration that
 can be  withstood without  effect. In simulated 96-h
 bioassays, the effect of increased tolerance to higher
 hydrophobicities was apparent  for chemicals whose
 K(sub ow) exceeded 10,000. These simulations  are
 compared to published observations. Simulations also
 are compared to other published data  for longer-term
 bioassays. The effect of interspecies gill morphology
 on toxic response also is explored. It is concluded that
 variation in lipid can account for much variation in toler-
 ance in  a subpopulation of similarly sized individuals;
 that  gill morphology  is another variable influencing
 toxic response;  and that, in general, for similarly ex-
 posed organisms, the fattest survives the longest.

 The spatial variability and temporal behavior of the ver-
 tical flux of ozone has been investigated from turbu-
 lence measurements collected on aircraft flight legs in
 the daytime period during two consecutive summer ex-
 perimental field studies. The data were obtained during
 horizontal flight legs conducted over agricultural crops
 and forested land in  southeastern Pennsylvania, cen-
 tral Ohio, and western Tennessee/Kentucky. Results
 from individual experimental cases and statistics de-
 rived from all cases in each  region are presented.
 Ozone flux generally exhibited  a significant height de-
 pendency; strongest negative (downward) fluxes in the
 lowest level flight legs were primarily attributed to the
 uptake of ozone by the surface and vegetative cover
 while values were near-zero in the middle of the con-
 vective boundary  layer in  the afternoon period. As
 ozone  flux was proportional to concentration, slightly
 higher  fluxes were found in low level downwind urban
 plume  segments where ozone concentrations were
 10-20 ppb higher than in the surrounding area. Derived
 deposition velocity showed no  such bias as a function
 of position across the urban plume. Ozone flux differ-
 ences  were not apparent between the more heavily
 forested sections and the  primarily agricultural crop-
 land areas in these regions. (Copyright (c) 1990 Kluwer

 Preparation of XAD-2 resin for indoor air sampling with
 commonly used cleaning methods, such  as Soxhlet
 extraction with  dtchkxomethane (DCM) followed by
 vacuum drying and nitrogen purging, can lead to ele-
 vated DCM levels (>100 ppb) in the sampled indoor
 air, which result from DCM remaining in the resin after
 cleaning. Since  DCM is a suspect human carcinogen,
 indoor human exposure to DCM  should be minimized.
 Several procedures to remove residual  DCM  after
 Soxhlet extraction were evaluated. Removal by fluidiz-
 ing the XAD-2 resin bed in a drying column with a nitro-
 gen stream at 40C was best. The effectiveness of this
 procedure was demonstrated in parallel air sampling
 with a syringe sampler and with a prototype quiet sam-
 pler equipped with a quartz fiber filter and an XAD-2
 cartridge in  series.  Sampling was conducted  in an
 office and in residences.  With  the modified proce-
 dures, indoor DCM levels were at typical indoor values
 (<10 ppb). (Copyright (c) 1990 American Chemical

 Two prototype high flow dichotomous samplers, each
 simultaneously collecting fine  (0.0-2.5 micrometers),
 coarse (2.5-10.0 micrometers), and total (0.0-10.0  mi-
 crometers) particle samples from a single air stream,
 have been designed and evaluated. A series of tests
 were conducted to estimate the prototype sampler col-
 lection efficiencies over a range of particle concentra-
 tions,  to compare prototype sampler collection effi-
 ciencies with standard particle monitors, and to evalu-
 ate relationships between particle size and sample
 chemistry. No statistical differences in particle collec-
 tion efficiencies were observed between the two proto-
 type samplers or between the prototype samplers and
 standard PM(10) and PM(2.5) high volume samplers.
 The study analytical results indicate that the particle
 bound organics are primarily associated with the fine
 particle sample and that the organics associated with
 the coarse particle fraction did not significantly contrib-
 ute to the total sample organic composition. The proto-
 type sampler can be constructed locally from routine
 sampler and machine shop components. The design
 minimizes the extensive resource requirements asso-
 ciated with low flow dichotomous sampling and is an
 excellent alternative  for  organizations  not having
 access to commercial low flow dichotomous  instru-
 mentation. (Copyright (c) 1990 Pergamon Press pic.)

 Sorption is one of the primary mechanisms for retard-
 ing the movement of organic contaminants in ground-
 water. Sorption of hydrophobia compounds such as
 toluene, naphthalene, and DDT is generally assumed
 to be linearly proportional to solution phase concentra-
 tion. In the present research naphthalene was chosen
 as a model compound. Batch adsorption  was studied
 from 0.01  to  1.00 mg/L Transport of  naphthalene
 through a specially designed soil column apparatus
 was studied from 5 to 9 pH and from 0.025 to 2.0 mg/L
 initial concentration. All transport  data could be mod-
 eled using a single pH-modified Freuncttich isotherm: q

Microbial pest control agents (MPCAs) are microorga-
nisms that are applied to agricultural and  silvacultural
environments to control proliferation and dissemina-
tion of insect or plant pests. During a field application,
it is likely that nontarget plants and animals are ex-
posed to MPCAs. Following extensive experimenta-
tion, protocols were developed using oral, intravenous,
and respiratory administration of the agent to two test
species of birds (mallard and bobwhite). These proto-
cols are suitably designed to demonstrate pathogenici-
ty of  microorganisms in the test  bird species. The
report summarizes the work completed during the de-
velopmeent and evaluation of these protocols.

 Because of current concerns regarding the release of
 genetically engineered microorganisms (GEMs) into
 the environment, the fate, survival, and effects of many
 GEMs will need to be  evaluated  in small-scale re-
 leases performed  in  controlled, contained  environ-
 ments. In the study, the use of greenhouses for pre-
 dicting the results of field releases, and the influence
 of bacterial genus, plant genus and environmental
 conditions on bacterial survival in the greenhouse and
 the field were investigated. Erwinia herbicola, Pseudo-
 monas  syringae,  and  Klebsiella  planticola  were
 sprayed on oat plants (Avena saliva) and bean plants
 (Phaseolus vulgaris) in  one greenhouse  experiment
 and in two field experiments. Plants  were sampled,
 and 21 days after bacteria were applied and tempera-
 ture, relative humidity, and incident light were recorded
 per minute and averaged per hour. Despite the appli-
 cation of equivalent bacterial concentrations in the ex-
 periments, bacterial populations after only one day
 post-application were significantly lower in the field ex-
 periments  as  compared to the greenhouse experi-
 ment.

Little is currently known about the response  of rice
plants to UV-B radiation, enriched CO2, or elevated
temperature. Even less is known about the responses
of important rice  ecosystem  components  (pests,
pathogens, weeds, nitrogen fixation, methanogenesis)
to these factors. To accurately determine the qualita-
tive and quantitative nature of these effects will require
a number of highly integrated experimental and model-
ing efforts, rigorous data quality control, and effective
coordination of research activities between cooperat-
ing groups. To facilitate integration of research activi-
ties, the program takes a modified cascading approach
with each task building upon the results of other tasks.
The research  tasks for the program  fall  into three
groups:  climate scoping, experimental, and assess-
ment

clude some waste paper; film; empty containers; used
blankets; and damaged products and other items. The
wastes result from  image processing, plate making,
proof making, printing, and finishing processes. An-
other form of waste - wastewater - results from image
processing, plate  making,  and printing processes.

 Most U.S. households pay for solid waste collection
 and disposal  services directly through  a fixed monthly
 service charge  or  indirectly  through their property
 taxes. Increasingly, however, communities are turning
 to unit pricing as a means of financing solid waste col-
 lection  and  disposal. Unit pricing means charging
 households for waste services based on the amount
 and type of waste collected: households that use more
 of the service pay more for waste collection and dis-
 posal. The unit  price  can be  assessed based on
 weight, volume, or some combination of weight and
 volume.

 The Illinois hazardous waste cleanup program, 'Clean
 Illinois', began in 1984 with S20 million in excess inter-
 est from the investment of old bond sale proceeds. Be-
 ginning in  FY 1986, additional funding was provided
 through the use of Build Illinois funding for cleanup
 projects. Since  the first year  of the program, annual
 funding has fluctuated between $5.9 million and $17.0
 million. When the PRPs did not pay for cleanup either
 because of insufficient assets, bankruptcy, or other
 reasons, or when they succeeded in hiding behind in-
 corporation or bankruptcy laws, State funding became
 necessary. A successful cleanup operation was put
 into place  over the past five years. The cleanup of 59
 hazardous waste sites and the significant number  of
 leveraged  responsible party cleanups testify to the ef-
 fectiveness of the Illinois cleanup machine. A bill was
 introduced in the 1990 session  of the Illinois General
 Assembly to fund the cleanup program through the as-
 sessment of a fee on the storage of hazardous chemi-
 cals.

The  objective of the study was to determine whether
resistance to immunosuppressive drugs by transplant
recipient's T cells could contribute to continued graft
rejection, in spite of immunosuppressive therapy. The
T cell  lines used in the series of experiments  were
originally established from T cells that had infiltrated
kidney or liver grafts and initiated rejections in patients
receiving  immunosuppressive  drugs, including the
purine analogue azathioprine (AZ). The authors  have
used a proliferation assay and the Strauss-Albertini
test to analyze the T cell lines. Both assays use 6-thio-
guanine (6-TG), an amino derivative of AZ, as the se-
lective agent to measure the resistance to AZ. (Copy-

1-Chloromethylpyrene has been evaluated as a model
mutagen and toxin related to the ultimate electrophiles
derived from BaP and 1-nitropyren.  It was mutagenic
to Salmonella (> 100 picograms/plate) and exception-
ally reactive to DNA when assessed by the postlabel-
ing assay. 1-CMP was inactive  in  a mouse  bone
marrow micronucleus assay when administered  by
gavage probably due to hydroylis whose kinetics  have
been studied (half life 23 min at 37 C). However as ex-
pected it was a potent skin toxin as determined by its
activity as a mitogen to mouse skin and its contact al-
lergenicity, as determined using the local  lymph node
proliferate assay.  It is concluded that 1-CMP will
probably be a potent human skin carcinogen and con-
tact  allergen.  (Copyright  (c)  1990  Elsevier Science

Estradiol-17 beta (E) rapidly (5-12h) induced ovine pi-
tuitary cultures to increase their binding for des-Gly10-
(D-Ala6)-GnRH  ethylamide by  2.5 to 4.5-fold. The
ED50 for E was near 0.1 nM. Scatchard analysis indi-
cated the E increased binding by increasing receptors
for gonadotrophin releasing hormone (GnRH). GnRH-
stimulated release of luteinizing hormone (LH) in-
creased 2-fold along with the increase in GnRH recep-
tors but heightened responsiveness to GnRH disap-
peared after 27h of E-treatment even though GnFjH re-
ceptors remained elevated. These data are consistent
with the concept that: (1) E increased GnRH receptors
which initially enhanced gonadotroph responsiveness
to GnRH, and  (2)  E subsequently nullified the in-
creased response to GnRH by blocking a mechanism
of LH secretion  not associated with  GnRH receptor
number. Further support for this hypothesis came from
studies with porcine follicular inhibin. Inhibin, in  ovine
pituitary culture, concomitantly increased GnRH re-
ceptors by 5-fold and GnRH-stimulated LH secretion
by 2-fold. Inhibin maintained both  effects long term

 A class of  curvilinear dose-response relationships in
 lexicological  and  epidemiological  studies may be
 roughly described by 'U-shaped' curves. Such curves
 reflect an apparent reversal or inversion in the effect of
 an otherwise toxic agent at a low or  intermediate
 region of the dose continuum. Several examples of y-
 shaped dose response functions are presented to il-
 lustrate the variety of agents and end points that can
 follow this form. Such findings are not thought to repre-
 sent a unitary phenomenon, but may  be explained
 through numerous possible principles or mechanisms,
 some of which are illustrated and discussed in general
 terms. U-shaped dose-response curves raise impor-
 tant issues for lexicological and environmental health
 risk  assessments, particularly  in the identification of
 no-observed-effect levels and in the evaluation of mul-
 tiple outcomes and trade-offs between potential risks
 and benefits of a given agent. It is especially important
 to avoid focusing exclusively on an apparent improve-
 ment in one end point and failing to consider other,
 possibly deleterious effects of the same agent.

Comparative intestinal nitroreductase, azo reductase,
beta-glucuronidase, dechlorinase, and dehydrochlorin-
ase activities in young male Fischer 344 rats and
young male CD-1 mice were measured in vitro while
the comparative biotransfprmation of 2, 6-dinitrotplu-
ene to mutagenic metabolites was determined in vivo.
The mice, which exhibit a high spontaneous incidence
of hepatomas, had markedly greater nitroreductase
activity and metabolized significantly more 2, 6-dinitro-
toluene to mutagenic metabolites than did Fischer 344
rats, which show a low incidence of liver tumors. Re-
sults of this study indicate that species differences in
the incidence of hepatomas may be influenced by mi-
crobial flora and/or the biotransformation of xenobio-
tics in the G.I. tract. (Copyright (c) Elsevier Scientific

Chromosome damage was studied in female B6C3F1
mice exposed to dichloromethane (DCM) by subcuta-
neous or inhalation treatments. No increase in either
the frequencies of sister chromatid exchanges (SCEs)
or chromosome aberrations (CAs) in bone marrow
cells was observed after a single subcutaneous injec-
tion of either 2,500 or 5,000 mg/kg DCM. Inhalation
exposure to DCM for 10 days at doses of 4,000 or
8,000 ppm resulted in significant increases in frequen-
cies of SCEs in lung cells and peripheral blood lympho-
cytes, CAs in lung and bone marrow cells, and micron-
uclei (MN) in peripheral blood erythrocytes. Lung cell
CAs and blood erythrocyte MN reached frequencies of
approximately two times control levels. Following a 3-
month inhalation exposure to 2,000 ppm DCM, mice
showed small but significant increases in lung cell
SCEs and peripheral blood erythrocyte MN. These
findings suggest that genotoxicity may play a role in
the carcinogenicity of DCM in the lungs of B6C3F1
female mice. (Copyright (c) Wiley-USS, Inc.)

During the last ten years, neurotoxicology has entered
the mainstream of environmental toxicology as evi-
denced by numerous national and international confer-
ences, formation of societies related to neurotoxico-
logy, establishment and support of journals devoted to
neurotoxicology and reliance of regulatory agencies
on neurotoxicological endpoints. Over the last ten
years, agreement seems to have been reached con-
cerning the need for and use of neurotoxicological
tests for hazard identification. With regard to the future
of neurotoxicology, there are a number of important
issues that deserve attention, including (1) arriving at a
commonly accepted definition of neurotoxicology, (2)
the impact of new technology, (3) development of bio-
logical markers for neurotoxicology, (4) neurotoxico-
logy of chemical mixtures, (5) relationship between en-
vironmental agents and neurodegenerative diseases,
(6) use of in vitro procedures in neurotoxicology, (7)
risk assessment and (8) development of database for
specific neurotoxicants. The last ten years have been
productive ones for neurotoxicology. The next ten
years should mark a new phase of development
marked by significant progress in a number of impor-
tant areas in environmental toxicology.

Some knowledge of the potential genetic activity of a
complex environmental mixture may be gained from an
assessment of the genetic activity of its component
chemicals. The expanded Genetic Activity Profile
(GAP) data base provides a computer-generated
graphic representation of genetic bioassay data as a
function of dose of the substance tested. In addition,
the Atmospheric Chemical Compound (ACC) data
base contains information on chemical structures,
properties, detection methods and sources of chemi-
cals found in ambient air. Using the combined data
bases, information on the quantity of an individual
chemical present within a mixture or fraction of a mix-
ture may be related to the quantity (lowest effective
dose, LED) of the chemical required to demonstrate a
positive response in one or more genetic bioassays.

Cyclopenta-fused polycyclic aromatic hydrocarbons
are a class of environmental PAH that has been re-
cently identified. Many of these chemicals have been
found to be more active that benzo(a)pyrene in tests
for genetic toxicity using bacterial and rodent cells.
Benz(l)aceanthrylene, a cyclopenta-polycyclic aromat-
ic hydrocarbon related to benz(a)anthracene, and
benzo(a)pyrene were compared for their activity to
induce cytotoxicity and anchorage independent colony
formation with normal human diploid fibroblasts. Both
benz(l)aceanthrylene and benzo(a)pyrene were rela-
tively non-cytotoxic to normal human diploid fibrob-
lasts. However, benz(l)aceanthrylene was twice as
active compared to benzo(a)pyrene over the concen-
tration range examined as an inducer of anchorage in-
dependent growth. The ability of benz(l)aceanthrylene
to induce anchorage independent colony growth in
normal human cells in combination with its demon-
strated ability as a mouse skin tumorigen suggests this
PAH to be a potential multi-species carcinogen. (Copy-

The environmental release of microorganisms has
prompted the investigation of potential health effects
associated with their release. In the study, survival and
translocation to the spleen and liver of several environ-
mental Pseudomonas spp. was investigated in antibi-
otic-treated mice. P. aeruginosa strain BC16 and P.
maltophilia strain BC6, isolated from a commercial
product for PCS degradation, P. aeruginosa strain
AC869, a 3,5-dichlorobenzoate degrader, and P. cepa-
cia strain AC1100, an organism that metabolizes 2,4,5-
trichlorophenoxyacetic acid were examined for their
survival capabilities in the intestines of mice dosed
with clindamycin, ianamycin, rifampicin, or spectinomy-
cin. A mouse intestinal isolate, strain PAMG, was in-
cluded in the study. Following antibiotic pretreatment
(1 mg twice daily for 3 days), mice were dosed by
gavage with 10 to the ninth colony forming units (CFU)
of the individual Pseudomonas spp. By the end of the 5
day test period, strains AC869 and PAMG survived in
kanamycin-, rifampicin-, spectinomyicn-, and clindamy-
cin-treated animals. A statistically significant (p 0.05)
increase in survival of strain AC869 and PAMG was
observed in clindamycin-treated mice for the test
period. (Copyright (c) 1990 American Society for

sponse in the upper airways of 10 normal volunteers
and compared these results to those obtained in the
lower airways assessed by bronchoalveolar lavage

 The albumin level, which is an indicator of epithelial
 cell permeability, was elevated 18 hours post exposure
 (1.5 fold). Interestingly, several other markers of acute
 inflammation such as prostaglandin E2 (PGEalpha),
 C3a, urokinase-type  plasminogen activator  (U-PA),
 which were found to  be  significantly  elevated in the
 BAL of the same group of subjects (18 hours post ex-
 posure), were not elevated  in the NAL either immedi-
 ately post or 18 hours post exposure. Collectively the
 data suggest that NAL may serve as a sensitive and

 Bacillus thuringiensis var. kyushuensis synthesizes an
 irregularly shaped parasporal inclusion during sporula-
 tion. Electron microscopy revealed that the inclusions
 are composed of a relatively homogeneous appearing
 center surrounded by a thick, electron dense coating.
 Purified inclusions were found to have an LC50 of 12
 ug/ml. against Aedes aegypti larva which is nearly 400
 times less toxic than similar preparations of B. thurin-
 giensis var. israelensis inclusions. The inclusions are
 composed  of  four  major peptides  with  molecular
 weights of about 140 kDa, 70 kDa, 26 kDa, and 14
 kDa. Blots of the inclusion peptides were prepared and
 probed with monoclonal antibodies  specific for the
 three major peptides present in B. thuringiensis var. is-
 raelensis inclusions. Antibody directed against the 135
 kDa B. thuringiensis var. israelensis peptide was found
 to cross react strongly with the 70 kDa peptide of B.
 thuringiensis var. kyushuensis. The antibody directed
 against the 65 kDa peptide of Bacillus thuringiensis
 var/ israelensis was found to strongly react with the 26
 kDa peptide of B. thuringiensis var. kyushuensis. How-
 ever, the antibody directed against the 28 kDa peptide
 of B. thuringiensis var.  israelensis failed to react with
 any of the B. thuringiensis var. kyushuensis peptides.

 Hansch analysis, a quantitative approach relating the
 physical-chemical properties of molecules to biological
 effects, was applied to a series of substituted phenols
 tested for developmental toxicfty. The physical-chemi-
 cal properties included a  hydrophobic parameter (log
 P), an electronic parameter (Hammett sigma)  and a
 bulk parameter (molar refractivity (MR)). Biological ac-
 tivities were obtained for 27 congeners in a Chemoff /
 Kavlock Assay performed in Sprague-Dawley rats ex-
 posed on day 11 of gestation. The effects discussed in
 the report are: the dose to decrease maternal weight
 gain by 10 g at 24 and 72 hours after treatment
 (MTOX1 and MTOX2); the dose to increase post-im-
 plantation loss by one over the concurrent control
 value (PLOSS); and the  dose  required to decrease
total liner weight by 10%  on postnatal day 6 (BIO6).
 Overall, 14 of 27 congeners were classified as active in
 terms of maternal effects,  but only 50% of these were
active for developmental  effects. Seven of the nine
overall active developmental toxicants were  active
maternal  toxicants. Two QSAR  models were devel-
oped from the data, one relating to maternal toxicity for
 22 para-phenols and the other for the postimplarttation
 loss potency of the 8 most active para-phenols. The
 properties of these phenols which contribute to mater-
 nal toxicity are different from those inducing develop-
 mental effects.

 Reproductive  impairment  of double-crested  cormo-
 rants (Phalacrocorax auritis) and Caspian tems Hydro-
 progne caspia)  has  recently been observed in the
 Great  Lakes of North America. Planarchlorinated hy-
 drocarbons (PCHs), which include polychlorinated bi-
 phenyls   (PCBs), polychlorinated dibenzo-p-dioxins
 (PCDDS), and polychlorinated dibenzofurans (PCDFs),
 are believed to be at least partially responsible for the
 increased incidence of teratogenesis and embryonic
 mortality. The objective of the study was to assess the
 potency  of  the  PCH  mixtures in  egg extracts from
 these colonial waterbirds. The evidence is strong for at
 least a partial role of PCHs as causal agents in the re-
 productive impairment of fish-eating waterbirds from
 the Great Lakes of North America. (Copyright (c) 1990

 Chinook salmon  (Oncorhynchus tschawytscha) was
 evaluated and compared to the status of two hepatic
 enzyme systems  proposed as sensitive biochemical
 indicators of  exposure to planar polychlorinated aro-
 matic hydrocarbons, including certain polychlorinated
 biphenyls,  polychlorinated  dibenzofurans  and  poly-
 chlorinated dibenzodioxins. Fertilizability, hatchability
 and egg and fry mortality  varied significantly among
the fish. Hepatic monooxygenase and glutathione S-
transferase activities and cytochrome P-450E concen-
tration also varied markedly among the fish. There
was, however, little correlation between reproductive
success and the three biochemical indicators of con-
taminant exposure.

Synthetic pyrethroid  insecticides are photostable ana-

structures range from very similar  to the original (e.g.,
allethrin) to highly dissimilar compounds (e.g., flucyth-
rinate). Directed synthesis by groups in Japan (Sumi-
tomo Chemical Co.) and England  (NRDC) resulted in
very potent insecticides and a commercial success for
the  synthetic pyrethroids.  (Copyright  (c)  1989  by

radon concentrations were found in several adjacent
houses. The U.S. EPA screened 56 of the houses and
selected 10 for demonstration of radon reduction tech-
niques.  Each of  the 10 houses received an intensive
radon diagnostic evaluation before a house-specific
radon reduction plan was developed. Before and after
the  plans were  implemented,  radon  concentrations
were determined by charcoal canisters and continuous
radon monitors.  A  variety of sealing and subslab de-
pressurization techniques were  applied to the  10
houses. Radon concentrations were reduced by over
95% in  all 10 houses. Five meetings were held to ex-
plain to homeowners the radion reduction techniques
being implemented and to answer questions of home-
owners  interested  in applying similar radon reduction
efforts to their houses.

Three numerical models of watershed acidification, in-
cluding the MAGIC II, ETD, and ILWAS models, are re-
viewed, and a comparative study is made of the specif-
ic process formulations that  are incorporated in the
models to represent hydrological, geochemical, and
biogeochemical processes which affect the responses
of watersheds to acidic deposition. The models differ
notably in the level of detail with which they represent
various processes and in the degree of aggregation

The study addressed the possibility that regional differ-
ences exist in the typical patterning of anterior pituitary
hormones seen over the estrous cycle. The results
show that LH in the rostral area of the pituitary, signifi-
cantly higher than in other regions on diestrus, rises
markedly on proestrus before falling late on that after-
noon to concentrations comparable to other areas.
Smaller cyclic changes were seen for lateral and
caudo-central areas. The pattern of regional FSH con-
centrations on diestrus, while similar to LH, does not
show the proestrus fall in the rostral region. Prolactin
declines from a high on diestrus I to a low on late
proestrus, but no regional disparities are present. TSH
shows distinct regional differences and a fall in con-
centrations that coincides with the reported rise in
serum estradiol. (Copyright (c) 1989 by Marcel Dekker,

The use of nuclease P1 treatment and 1-butanol ex-
traction to increase the sensitivity of the 32P-postla-
belling assay for DNA adducts have been compared.
Although similar results were obtained with the two
methods for standard adducts formed with
benzo(a)pyrene dipl epoxide I, nuclease PI treatment
resulted in a significant reduction in detection of major
adducts 1-amino-6-nitropyrene, 1-amino-8-nitropyr-
ene, 2-aminofluorene, 2-naphthylamine and 4-amino-
biphenyl modified DNAs, but not following the 32P-
postlabelling analysis of 2-acetylaminofluorene modi-
fied DNA. These results suggest that at least initially,
both medications of the 32P-postlabelling assay
should be used for the detection of unknown adducts
or for adducts derived from nitro-aromatics and aro-
matic amines. (Copyright (c) 1989 Elsevier Science

The presence of a high molecular weight polypeptide
growth factor in the plasma of normal human or rat
serum which stimulates DNA synthesis in primary cul-
tures of normal rat hepatocytes has previously been
reported. This activity was referred to as Hepatopoietin
A (HPTA). At that time, however, complete purification
of this growth factor had not been achieved. In the
present report the steps required for complete purifica-
tion of HPTA from human plasma or rabbit serum are
described. The purification involved sequential ammo-
nium sulfate precipitation, heparin-affinity chromatog-
raphy, anion exchange HPLC, and reverse-phase
HPLC. The final purified product is a heterodimer con-
sisting of a heavy and a light polypeptide chain with
M.W. of 70,000 and 35,000 respectively as determined
by SDS-PAGE under reducing conditions. Under non-
reducing conditions, however, the purified HPTA mi-
grated as a single band on SDS-PAGE corresponding
to a M.W. of 69,000. The mitogenic activity of HPTA
was associated with this band when it was eluted from
unstained SDS-polyacrylamide gels. Gel filtration
HPLC under neutral isotonic conditions indicated that
HPTA tends to form aggregates with M.W. of greater
than 300,000. Chromatofocusing indicated that HPTA
is an acidic protein with a PI of about 5.5.

To characterize further the behavioral toxicity of ami-
traz, comparisons were made between the effects of
amitraz on motor activity, the acoustic startle re-
sponse, body temperature, and body weight in male
Long-Evans rats. Acute dosage-effect and time-
course determinations of motor activity were made
using figure-eight mazes. Dosage-effect and time-
course determinations for the acoustic startle re-
sponse were measured using a 13 KHZ, 120 dB(A), 40
ms tone as the eliciting stimulus, at each of three back-
ground white-noise levels. Amitraz was administered
orally in the vehicle ('Emulphor' + ethanol + saline.d a
dosage- and time-dependent decrease in motor activi-
ty which lasted from 4 to 96 h post-administration. The
effects of amitraz on the acoustic startle response
consisted of an increased latency and a decreased
amplitude and sensitization. The time-course of effects
on the acoustic startle response were more transient
(4-24 h) than the effects on motor activity. Amitraz-ex-
posed animals had decreased body weight that did not
return to control levels until 120 h (five days) post-ad-
ministration. (Copyright (c) 1989 Society of Chemical

NK cells, defined here as lymphocytes bearing the
CD16 Ag found on the NK cell Fc-gamma receptor
(FcR), are known to enter a proliferative and activated
state in response to stimulation with IL-2 as assessed
by clonal expansion, short-term DNA synthesis, and de
novo expression of lymphocyte-associated activation
Ag. We have found that the FcR of NK cells acts as a
signaling pathway through which IL-2-dependent acti-
vation may be greatly enhanced, allowing for more
rapid induction of activation Ag and recruitment of an
increased percentage of cells expressing surface
markers of cellular activation. FcR-interactive agents,
such as solid phase immobilized immune complexes
or cross-linked CD16-specific mAb, work synergistical-
ly with rlL-2 to elicit a rapid expression of IL2R and
transferrin receptors on greater than 5% of purified NK
cells as early as day 3 of culture. IL-2 or FcR-interac-
tive stimuli alone were weak or ineffective stimulators
by comparison. In contrast to the induction of de novo
activation Ag, DNA synthesis was elicited by IL-2
alone, but was not substantially or consistently en-
hanced by the subsequent addition of FcR-interactive
stimuli. (Copyright (c) 1989 by the American Associa-

The study had two objectives. The first was to deter-
mine the use of the physical habitat by the 25 most
common native freshwater fishes of Oregon, and the
second was to evaluate the use of a large computer
database of museum records in the determination. The
database encompasses 2021 collections made by var-
ious field workers from 1880 to 1984. Statistically dis-
tinct habitat use patterns appear for 17 of the species
for temperature, 17 for substrate, 19 for stream width,
and 22 for current velocity. Habitat use identified from
this statistical evaluation is generally consistent with
the subjective evaluations of field ichthyologists. A
large computer database compiled from field notes of
many collectors allowed useful generalizations con-
cerning species habitats.

The Cytotoxicity of four tumorigenic minerals,
erionite(w), erionite(c), UICC crocidolite, UICC chryso-
tile to Chinese hamster V79 cells was compared. The
results indicate that the minerals were toxic by show-
ing more than 50% toxicity for at least one dose be-
tween 10 and 100 micrograms. This confirms the pre-
vious findings that V79 Cytotoxicity corresponds to the
tumorigenic potentials of the mineral fibers. Higher po-
tency of erionite, however, was not evident in the
system when the dose considered was expressed in
mass units. On the other hand, when the degree of cy-
totoxicity was considered per number of mineral fibers,
it was clear that fewer erionite fibers of all three dimen-
sions (A greater than or equal to 3; L greater than or
equal to 8.0 micrometers, W less than or equal to 0.25
micrometers; and L less than or equal to 5.0 microme-
ters, W less than or equal to 0.1 micrometers) than
those of UICC crocidolite and UICC chrysotile were
needed to produce similar toxicity. This suggests that
the dose in number of fibers may be a better parameter
than the total mass dose as a correlate of tumorigenic
potential. (Copyright (c) 1988 by Academic Press, Inc.)

A system has been developed to measure  simulat-
neously the effects of inhaled toxicants on cardiopul-
monary function in four awake rats  before, during and
after exposure. One day prior to testing, Fischer-344
and Sprague-Dawley rats were implanted with an intra-
pleural or carotid catheter. On the  day of testing, the
rats were placed into a restraint  system  to reduce
movement artifacts and to keep rats from disturbing
the implanted catheters  without imposing  limitations
on  functional  measurements.  The rats  were then
sealed into constant-volume plethysmographs mount-
ed on the door of  a 0.32-cu m Rochester exposure
chamber. Thirty minutes after the rats were placed into
the plethysmographs, control measurements were ob-
tained. Under the control of a digital computer, the rats
were exposed for 15-min periods to 4% CO2. During
testing, tidal volume, intrapleural pressure, blood pres-
sure, and the electrocardiogram were recorded on the
polygraph, and were digitized and stored in the com-
puter. Four-second breathing epochs were recorded
and analyzed, and the results were displayed on line.

The interactions of aqueous solutions of chlorine with
some fruit acids (citric acid, DL-malic acid, and L-tar-
taric acid) at different pH values were studied. Diethyl
ether extraction followed by GC/MS analysis indicated
that a number of mutagens (certain chlorinated pro-
panones and chloral hydrate)  are present as major
products in some of these samples. A number of fruit
juices (orange, grape, apple, pineapple, and grapefruit)
were also treated with aqueous solutions of chlorine at
their pH values. The products were analyzed by GC/
MS. The same mutagens that were formed  by the pure
acids (citric acid and DL-malic acid) were identified as
major products in ether extracts of these samples. An-
other mutagen, dichloroacetonitrile, was also identified
as a minor product in some of these juice samples. All
of the major products observed in the chlorination of
all five fruit juices are potentially derived from reactions
of aqueous solutions  of chlorine with  citric or malic
acid and with trace amounts of acetaldehyde and ace-
tone in the juices. The minor product, dichloroacetoni-
trile, is likely derived from the chlorination of certain
amino acids in the fruit juices. (Copyright (c) 1988 by

Three different methods were compared for their effi-
ciency at detection of adenoviruses. The samples ex-
amined  for viral analysis consisted of concentrates
prepared from raw sewage, chosen as  being repre-
sentative of the spectrum of viruses being intestinally
shed from a large population at any given time. When
using one single cell line, HEp-2, the overall numbers
of adenoviruses detected using cytopathogenicity and
immunofluorescence were roughly equal. In-situ  hy-
bridization was approximately forty percent more sen-
sitive than eital. In-situ hybridization was approximately
forty percent more sensitive than either of these other
methods as determined by average virus tilers for the
different samples, and also proved to be  better  by
means of a  nonparametric comparison. The 293 cell
line was approximately five times more sensitive for
detecting adenoviruses by cytopathogenicity as com-
pared with the HEp-2 cell line, but proved unsuitable in
our  hands  for quantitatively  detecting indigenous
adenoviruses by  immunofluorescence.  The relative
number of indigenous adenoviruses  present in  the
sewage concentrates we examined was, on average,
ninty-four fold  greater than  that of enteroviruses.
Assay of enteroviruses  was performed by  plaque
assay in the BGM cell line.

In previous studies with hyperimmune rabbit sera and
monoclonal antibodies against P1 protein of M. pneu-
moniae, evidence was obtained of a shared antigenic
determinant with a single protein of M. genitalium. Be-
cause of biological and morphological similarities be-
tween these two human Mycoplasma  species,  at-
tempts were made to  characterize this cross-reacting
protein of M. genitalium (designated MgPa). The pro-
tein was surface exposed, and had an estimated mo-
lecular weight of 140  K daltons. Electron microscopy
using monoclonal antibodies produced against either
MgPa or P1 demonstrated that MgPa is located over
the surface of the terminal structure of M. genitalium
which is covered by a nap layer. These immunologic
and morphologic findings suggest that the MgPa pro-
tein of M. genitalium could be the counterpart of the PI
protein of M. pneumoniae. (Copyright (c) 1987, Ameri-

 Solid silicone rubber casts of the nasopharyngeal and
 laryngeal regions of  a  human cadaver (child, three
 years old) and a laboratory primate (baboon, 10 years
 old) were made and cross-sectional areas were meas-
 ured in detail. Cross-sectional areas of other species
 reported in the published literature were used for com-
parison. In the child's nose cast, the frontal nasal duct,
which enters the anterior part of the middle meatus,
and the sphenoidal recess were almost absent. The
ethmoidal turbinates and the maxillary turbinates were
present but were not fully developed. In the baboon
nose, the  different  turbinates were well defined and
smooth but of less complex nature. Of the species
compared, the baboon's upper airways had the great-
est similarity to  the human child's. The study shows
that for the species investigated and for those from the
literature, the cross-sectional area increases from the
external nares to the maxilloturbinate region. There is
a relatively sudden drop in cross-sectional area about
halfway through the nose. The study suggests a func-
tional relationship between nasal structure and cross-
sectional area across  species.  (Copyright  (c) 1986

Antagonism of NMDA-mediated transmission by MK-
801  has been shown to block long-term potentiation
(LTP) in vitro and delay electrical kindling of the amyg-
dala. The  experiment sought to examine the relation-
ship between synaptic potentiation of the perforant
path-granule cell synapse and development of perfor-
ant path kindling. MK-801  (0.1 and 1.0 mg/kg) blocked
induction of LTP of the perforant path in the unanesth-
etized animal measured 24 h after train delivery. The
1.0 mg/kg dosage also increased afterdischarge (AD)
thresholds,  delayed  kindling development from daily
stimulation of the perforant path (x = 8.82 + or - and
22.9 + or - 3.66 sessions to the first stage 5 seizure),
and increased AD durations. Kindling produced a sig-
nificant potentiation of the EPSP (47%) and population
spike (49%) after the first evoked AD in control ani-
mals. No significant enhancement of either component
of the field potential was  observed in MD-801-treated
animals. Animals treated  with this dosage of MD-801,
did, however,  kindle in the absence of potentiation at
this synapse.  It was concluded that although  NMDA-
mediated  potentiation may facilitate kindling, synaptic
potentiation does not appear to be a critical require-
ment for kindling to develop. (Copyright (c) 1990 Else-

 evoked potential  (VEP) using procedures similar to
 those used in  humans. Evoked potentials were record-

 stimulation over a range of spatial frequencies, and fol-
 lowing adaptation to a stationary grating of the same
 spatial frequency as the test stimulus. The initial VEP
 component, a positive peak labeled PI, was early in la-

negative peak labeled N2 which was largest at inter-

properties suggest that N2 reflects the activity of a pat-

To control toxic pollutants in effluents, it is necessary
first to identify the toxicants. To make identification
possible it is desirable to isolate the toxicants from
their effluent matrices and concentrate them. The arti-
cle describes a simple method in which the nonpolar
organic fraction of an effluent is concentrated into
methanol. The methanol solution can be directly ana-
lyzed by GC-MS and can also be diluted and tested for
toxicity. Results from the laboratory where this method
is being used show that in cases where the effluent
toxicants were nonpolar organic compounds 60% of
the effluent's toxicity was recovered in the methanol
concentrate and the toxicants were identified by GC-
MS.

Mercury contamination of the fishery affects hundreds
of lakes and rivers in the Upper Midwest and around
the Great Lakes (1-4). In Minnesota, fish consumption
advisories restricting full utilization of the resource be-
cause of elevated levels of mercury have been issued
for 285 water bodies compared to the limited database
of 22 water bodies 10 years ago. In December 1988 in
the broadest health warning issued on inland lakes,
Michigan's Department of Public Health announced
that people should limit consumption of fish from all of
the state's 10,000 inland lakes because of mercury
contamination. In the Great Lakes the International
Joint Commission (IJC) identified 42 areas of concern
for the development of plans for mitigation of pollution
problems (5).

Duckweed (Lemna minor), a small vascular plant,
grows rapidly, is sensitive to a wide variety of toxicants
and is easy to culture. A method is described that
measures duckweed frond growth and chlorophyll
levels as indicators of growth inhibition. The method
requires a small testing volume (15 ml) of reconstituted
test medium that is prepared by using commercial
grade soil to promote frond and chlorophyll production.
A variety of single toxicants, industrial effluents and
wastewater treatment plant effluents were tested. For
most chemicals, the duckweed was as sensitive as
other frequently used test species. The comparative
toxicities to Ceriodaphnia dubia and fathead minnows
(Pimephales prpmelas) with various effluents indicates
that, for some industrial effluents, duckweed was the
most sensitive indicator used.

Orthogonal polynomials have been applied to correct
for spectral interferences in ICP-AES. The emission
spectra of many analytes measured over fairly wide
wavelength ranges have characteristic normal proba-
bility distribution profiles (quadratic pattern) centering
on the prominent line of each element. The emission
spectra of many interferents (with the exception of
direct line overlap) display more or less linear shapes
over the same analyte range. Accordingly, a quadratic
polynomial fitting results in coefficient values that
relate largely to the concentration of the analyte and
negligibly to the concentration of interferents. The
method has been demonstrated to cancel the interfer-
ence caused by the presence of 1000 mg/1 concen-
trations of Ca, Mg, Al and Fe in the analysis of selected
elements (Cr, Cu, Mn, P, Zn, S, and Pb) at their most
sensitive prominent lines. The results indicate not only
the efficacy of the proposed method for eliminating
such interferences, but also its superiority over the cur-
rently used two- and three-point correction proce-
dures.

A quantitative method is described for testing whether
model predictions fall within a specified factor of true
values. The technique is based on classical theory for
confidence regions on unknown population param-
eters and can be related to hypothesis testing in both
univariate and multivariate situations. A capability
index is defined that can be used as a measure of pre-
dictive capability of a model, and its properties are dis-
cussed. The testing approach and the capability index
should facilitate model validation efforts and permit
comparisons among competing models. An example is
given for a pesticide leaching model that predicts
chemical concentrations in the soil profile. (Copyright

Biological processes, including microbial degradation,
have been identified as critical mechanisms for attenu-
ating organic contaminants during transit through the
vadose zone to the groundwater. On-site soil remedial
measures using biological processes can reduce or
eliminate groundwater contamination, thus reducing
the need for extensive groundwater monitoring and
treatment requirements. On-site remedial systems that
utilize the soil as the treatment system accomplish
treatment by using naturally occurring microorganisms
to treat the contaminants. Treatment often may be en-
hanced by a variety of physical/chemical methods,
such as fertilization, tilling, soil pH adjustment, mois-
ture control, etc. The development of a bioremediation
program for a specific contaminated soil system in-
cludes: (1) a thorough site/soil/waste characteriza-
tion; (2) treatability studies; and (3) design and imple-
mentation of the bioremediation plan.

A large body of literature describes the processes af-
fecting the fate of microorganisms in the subsurface
environment (i.e., soil and groundwater). The fate of
microorganisms depends on two main components:
survival and transport. Both components must be con-
sidered when determining whether there is a hazard to
human health associated with the contamination of the
groundwater. If a microorganism can survive in the
subsurface but is not readily transported through the
soil, it likely does not pose a large threat. Similarly, if it
is easily transported but does not persist, it may not be
of much concern. However, if a microorganism sur-
vives in an infective form long enough to be transport-
ed through the soil and into the groundwater, it may
contaminate the water supply.

Sorption of hydrophobic organic chemicals (HOCs) by
two soils was measured from mixed solvents contain-
ing water plus completely miscible organic solvents
(CMOSs) and partially miscible organic solvents
(PMOSs). The utility of the log-linear cosolvency model
for predicting HOC sorption from solvent mixtures was
evaluated. Co-solvent effects of PMOSs on HOC solu-
bility and sorption were compared. Nonpolar PMOSs
(such as toluene, p-xylene, and TGE) have low aque-
ous solubilities and when present either as a cosol-
vent/cosolute in the aqueous phase or as a separate
liquid phase do not significantly influence HOC sorp-

tion by soils. In contrast, polar PMOSs (such as nitro-
benzene and o-cresql) have sufficiently high aqueous
solubilities that significant decreases in HOC sorption
can be measured. The presence of a CMOS increases
the PMOS solubility which in turn, is reflected in in-
creased solubility and decreased sorption of  HOCs.

Sorbent and solvent characteristics influencing sorp-
tion of pentachlorophenol (PCP) were investigated.
Analysis of aqueous sorption data for several sprbents
over a broad pH range  suggested hydrophobic sorp-
tion of neutral PCP predominates at pH<7. At pH>7,
sorption of the pentachlorophenolate  anion PCP(-1)
and the formation and  sorption of neutral ion pairs
(such as metal cation (M(+) +  PCP(-1) = MPCP(o))
were considered. The observed sorption data were de-
scribed over the entire pH range with knowledge of pH,
soil organic carbon content, and  PCP's pKa. Increased
sorption of PCP(-1) was observed with increasing ionic
strength for batch sorption studies conducted in aque-
ous CaCI2 solutions. Octanol-water partition  coeffi-
cients measured in various electrolyte solutions sug-
gested that formation of MPCP(o) and the partitioning
of PCP(-1) are influenced by the cationic  species.

The cosotvency of completely miscible  organic sol-
vents (CMOSs) and partially miscible organic solvents
(PMOSs) on  the  solubility of  hydrophobic  organic
chemicals (HOCs) was examined, with an emphasis on
PMOSs.  Measured solubilities were compared  with
predictions from the log-linear model and the UNIFAC
model. In ternary mixed solvents, nonpolar  PMOSs
such as toluene and trichloroethylene  did not appre-
ciably increase HOC solubility. However, polar PMOSs
such as o-cresol and nitrobenzene did significantly en-
hance HOC solubility. Polar PMOSs have greater co-
solvent effect, not because they are stronger solvents,
but because they are present in greater concentrations
as a result of their higher aqueous solubilities (10,000
mg/L or 1% volume  fraction).  The  cosolvency of
CMOSs increases with decreasing solvent polarity,
whereas the opposite is true for PMOSs. (Copyright (c)

The association of contaminants with suspended col-
loidal material  in groundwater is a possible transport
mechanism and a complicating factor for accurate es-
timations of the aqueous geochemistry of subsurface
systems. Research to date indicates colloidal facilitat-
ed transport of contaminants in groundwaters, surface
waters, and in the unsaturated zone. If continued re-
search shows colloidal transport of contaminants to be
significant, sampling methods and transport models
must consider and be sensitive to this transport and re-
action mechanism.

The  osmoprptectant betaine  was incorporated into
collection fluid and enumeration medium to determine
its effects on the colony-forming abilities of airborne
bacteria, which were collected from three separate lo-
cations: a wastewater treatment plant, the roof of a
laboratory building, and an unobstructed farmland. At
all locations, addition of 2 to 5 mM betaine caused a
significant increase (from 21.6 to 61.3%)  in colonial
outgrowth, compared with the growth rate of controls
without betaine. The presence of betaine in both the
collection fluid and the enumeration medium had an
additive effect on the colony-forming ability of airborne
bacteria compared with the presence of  betaine in
either one alone. The effect of various betaine concen-
trations on the enumeration of aerosolized Pseudo-
monas syringae was determined. Betaine showed a
threshold for maximum effect at a concentration of 2 to
5 mM. The significance of these results with respect to
the development of protocols  for monitoring airborne
microorganisms,  including  genetically  engineered
microorganisms, is discussed.

Nutrient export  from intact  soil-core microcosms in
leachate or by plant uptake was evaluated as a means
to assess the ecosystem impacts from the environ-
mental release of genetically modified root-colonizing
bacteria. Intact  cores of two  soil  types, a Burbank
sandy loam and an Palouse silt loam, were excavated
for use as microcosms, seeded with corn and wheat,
respectively,  and inoculated with Azospirillum  lipo-
ferum transposon  Tn5 mutants. Microcosms were
leached at 33 d and 67 d after seeding and the leach-
ate analyzed  for sulfate, phosphate, ammonium, ni-
trite, nitrate, dissolved organic carbon and inorganic
carbon.  Statistically significant differences in leachate
nutrient  concentrations between treatments were due
to differences in soil types, rather than inoculation with
the bacteria. The high variation in the concentrations
of nutrients in the leachates from replicate micro-
cosms, attributed to real field variation, suggest that
the measurement of nutrient export in leachate from
microcosms may not be a sensitive indicator of eco-
system impacts. One exception was dissolved organic
carbon(and total carbon). A statistically significant dif-
ference  (p <  or = 0.05) was observed between  the
microcosms receiving live inoculum and those receiv-
ing heat-killed cells for leachate organic carbon con-
centration. Plant uptake of N, P, S, B, Cu, Fe, Mg, Mn
and Zn was not affected by inoculation but the coeffi-
cients of variation were considerable lower than for the
leachate analyses.  It is suggested that although  the
leaching of organic carbon from microcosms may be
used as a holistic indicator of ecosystem impacts from
the    release    of    genetically    engineered
microorganisms(GEMs), measurements of plant  as-
similation of nutrients and specific rates of micrpbial
transformation of nutrients may provide more sensitive
effects and points. (Copyright (c) 1990 SETAC.)

Using newly available regional data sets we examine
the potential for future changes in stream acid neutral-
izing capacity (ANC) for the Southern Blue Ridge Prov-
ince (SBRP) of the U.S. as related to (1) levels of S
deposition, (2) retention of  S  within watersheds, (3)
current surface water SO4, and (4) potential historical
changes in surface water chemistry. The authors con-
clude that, although  (1) little change in surface water
chemistry  (as affected by acidic deposition) likely has
occurred in the region to date, and (2) soils are current-
ly retaining a majority of atmospherically deposited S, it
is likely that marked increases in  surface water SO4
will occur. Such increases could be accompanied by
significant surface water acidification (loss of ANC).

scribes the combined effects of dose-level exposure
and time-duration exposure  using 570 96-hr toxicity

along the dose and time axes for each chemical in
these tests were completely defined by two scale fac-
tors, one  for dose and one for time, and two form fac-
tors, one  for dose and one for time. The scale factors
for dose and time are proportional with the inverse of
LC50 and LtSO, respectively. The form factors meas-

Environmental Protection Agency conducted the Na-
tional Stream Survey (NSS) to provide unbiased esti-
mates of the numbers and distribution of acidic and
low acid neutralizing capacity streams in the Mid-Atlan-
tic and Southeastern United States. The NSS em-
ployed a probability sample of 500 stream reaches to
represent a target population of 64,300 stream
reaches in the study area. All NSS samples were
screened for acid mine drainage (AMD) influences,
and population estimates of the regional extent of
AMD impacts were made. Almost 10% of the streams
reaches in the Northern Appalachians subregion were
acidic during spring baseflow due to AMD. The popula-
tion estimates of mine drainage impact made in the
NSS were similar to estimates made in previous sur-
veys that attempted to census all of the streams in
coal producing areas. The results demonstrate that a
statistically based stream survey is a useful tool for
evaluating regional water quality.

Free-living female red-winged blackbirds were cap-
tured on their nests and given oral doses of 0, 2.37 or
4.21 mg/kg methyl parathion in a propylene glycol car-
rier during incubation. Birds were released immediately
after dosing and observed for 5 h to document behav-
ioral effects, amount of time spent off the nest after
dosing and time spent incubating. Each nest was mon-
itored until nestlings fledged or until all nestlings died
or disappeared. For each nest, the time of abandon-
ment, hatching success and fledgling success were
determined. In addition, prefledgling weights were ob-
tained for all nestlings in nests at 8 d after hatch. Al-
though methyl parathion caused ataxia, lacrimation
and lethargy and significantly depressed cholinester-
ase activity (>35%) at 4.21 mg/kg, there were no ap-
parent adverse effects on reproduction. Females re-
ceiving 4.21 mg/kg methyl parathion were able to
return to their nests, resume incubation, successfully
hatch their clutch and rear their young. Nestlings of
poisoned females did not have significantly different
body weights at 8 d compared to controls, indicating
that methyl parathion did not disrupt the females; abili-

The irnmunomodulation response of mice to low levels
of aldicarb in drinking water was investigated in four
series of studies. The splenic plaque forming cell(PFC)
response to red sheep cells were measured for treat-
ment levels of 0.01 to 1000 ppb(micrograms/kg).
Based on their beginning and end body weights, the
animal populations were uniform in all series of tests,
but based on their net body weights and PFC counts
they were highly nonuniform in the 30 to 60 day tests
and uniform in the 90 and 180 day tests. The mean
PVC counts for animals in each treatment were calcu-
lated and compared with the mean PFC counts for ani-
mals in the controls in all four series of tests. This ap-
proach ignores the variability and nonunifprmity in the
animal population. The outcomes using this approach
were stimulatory for the 30 and 60 day tests and inhibi-
tory for the 90 and 180 day tests. An alternative ap-
proach was developed based on the analysis of the
distributions of the relative PFC counts of each animal
in a treatment with each animal in a control, and spe-
cifically addresses the variability and nonuniformity in
animal population as integral parts of the analysis.

The pH is not sufficient to characterize the acidity of
precipitation, but rather its acid-base components
must be described. The chemistry of natural emission
sources as well as the mechanism of precipitation for-
mation determine the chemistry of precipitation at mid-
latitude, Northern hemisphere locations. With the
ocean biota as a source of atmospheric aerosol SO(2/
4), it is expected that this 'background' chemistry will
be dominated by SO(2/4). For the purpose of the
study, background was defined as a remote site gener-
ally upwind of urban areas, with the additional require-
ment that samples with evidence of contamination by
anthropogenic sources be excluded. Canadian and
U.S. data from long term precipitation monitoring sites
along the coasts of British Columbia, Oregon, and
Washington were evaluated to estimate a background
SO(2/4) concentration in rainwater.

Data present in the PHYTOTOX data base were ana-
lyzed to determine the influence of greenhouse vs field
conditions, and of taxonomic differences on the re-
sponse of terrestrial plants to a wide range of herbi-
cides. In the greenhouse vs field analysis, consider-
ation was given to the response of 13 plant species to
1 or more of 17 chemicals. The influence of taxonomic
differences was examined by comparing the response
of 151 plant species (43 families) to 1 or more of 16
chemicals representing 11 different classes of herbi-
cides. Analysis of this large body of comparative data
drawn from approximately 230 published papers would
not have been feasible without the use of computer-
ized data assembled in PHYTOTOX. These analyses
showed that the magnitude of variability between labo-
ratory and field data was 1.8 with a confidence interval
of + or - 0.4. Thus, the study indicates that taxonomic
differences among plants have a much greater influ-
ence on plant response to chemical treatment than
does testing condition (greenhouse vs field).

The objective of the paper is to provide a checklist of
items to be addressed when compiling and reporting
diatom and chrysophyte calibration data sets and ac-
companying ecological data and inference equations.
The purpose of the list is to promote completeness
and consistency in data together with proper presenta-
tion and adequate documentation, so that the data can
be thoroughly evaluated and used fully and effectively
by others. It is recommended that as many items on
the list as possible and practical be addressed in all
papers reporting calibration data sets submitted to sci-
entific journals. The list is based on experience, re-
viewing papers on calibration data sets, discussions
with calibration set developers and users, and at-
tempts to compile data sets from several regions. The
guidelines can be applied to calibration data sets
based on other organisms as well.

Variability in forest soils makes it difficult to observe
short-term changes in chemical properties under field
conditions. A buried soil-bag technique was developed
to examine the chemical response of a Maine forest
soil to loadings of strong acids (HNO3 and H2SO4).
Acids were added by irrigation on 18 hardwood plots,
15 by 15 m, American beech (Fagus grandifolia Ehrh.)
dominating. Treatments with three replicates each,
were control, low S, high S, low N, high N, and N plus
S. Soils were typical northeastern Spodpsols, with
acidic forest floors (pH 3.6) and upper mineral soils
(pH 3.4-4.0), low concentrations of base cations in
mineral horizons, and enrichment of the spodic hori-
zons with organic C, N, and S. Relative standard devi-
ations (RSD) of horizon means for all chemical proper-
ties except pH showed large variability over the small
(2.2 h) area encompassed by the plots. Twenty-five
250-micrometers-mesh nylon bags filled with 300 g of
homogeneous B horizon soil were placed directly
below the forest floor in each plot. After a 1 year of
treatment, collection and analysis of three bags per
plot showed significant differences. Mean adsorbed

SO(-2)4 concentrations were 48 and 92 micrograms
S/g in control and high-S treatments, respectively. Ex-
changeable Ca(2+) and Mg(2+) were greater in the
high-S treatment than the control; base saturation in-
creased from 5.9 to 8.5% (possibly due to displace-
ment of cations from the forest floor). The buried soil-
bag technique detected small alterations in forest soil
chemistry under field conditions, with minimal disturb-
ance to study plots.

 The paper describes an experimental study of the drag
 of two- and three-dimensional bluff  obstacles of vari-
 ous cross-stream  shapes when towed through  a fluid
 having a stable, linear density gradient with Brunt-Vai-
 sala frequency, N. Drag measurements were made di-
 rectly using a force balance, and effects of obstacle
 blockage (h/D, where h and D are the obstacle  height
 and the fluid  depth,  respectively)  and Reynolds
 number were effectively eliminated. It is shown that
 even in cases where the downstream lee waves and
 propagating columnar waves are of large amplitude,
 the variation of drag with the parameter K (=ND/U) is
 qualitatively close to that implied by  linear theories,
 with drag minima existing at integral values of K.  Under
 certain conditions large, steady, periodic variations in
 drag occur.  Simultaneous drag  measurements and
 video recordings of the wakes show  that this unsteadi-
 ness is linked directly with time-variations in the lee
 and columnar wave amplitudes. It is argued that there
 are, therefore, situations where  the inviscid flow is
 always unsteady even for large times; the consequent
 implications for atmospheric motions are discussed.

A procedure is described for fitting multimodal log-
normal size distributions to cascade impactor data.
The method was tested by applying it to published cas-
cade  impactor measurements for ammonium and ni-
trate that were previously analyzed by procedures that
do not assume a functional form for the size distribu-
tion. Small differences between results of the methods
are noted. Monte Carlo simulations are used to evalu-
ate the sensitivity of  the deduced size distribution  pa-
rameters to measurement precision and impactor effi-
ciency characteristics.  Unbiased parameters and reli-
able estimates of their uncertainties were obtained
when correct specifications of measurement precision
and impactor characteristics were used in the analysis.
However, when incorrect specifications were  used,
biased parameters  and unreliable uncertainty esti-
mates were obtained.

Large sulfate artifacts up to 2 micrometers in diameter
were observed by scanning electron microscopy for
the fine particle fraction collected in dichotomous sam-
plers. The artifacts were attributed to small liquid parti-
cles that piled up on the filter, coalesced, and later
dried as larger particles. Such artifacts were eliminated
when particles were  collected in a modified dichoto-
mous sampler in which 80% to 90% of the airflow was
diverted from the fine fraction filter. This airflow diver-
sion technique was used successfully with both virtual-
impactor and tandem-filter types of dichotomous sam-
plers. (Copyright (c) Elsevier Science Publishing Co.,

The paper gives results  of a comparison of several
standard materials and techniques for the Warren-
Averbach determination of microstructure characteris-
tics of calcium hydroxide~Ca(OH)2-sorbent materials.
The comparison is part of an investigation of the injec-
tion of dry Ca(OH)2 into combustion streams for the re-
moval of sulfur oxides (SOx). It has been known, for
some time, that the reactivity for removal of SOx varies
over a wide range for different batches of Ca(OH)2.
Because reactivity is a critical factor in the economics
of the process, a method to predict the reactivity of
Ca(OH)2 batches is desirable. Reactivity can be affect-
ed by many factors, including the origin of the calcium
carbonate  mineral  from which  the hydroxide is pro-
duced, production conditions, and the presence of ad-
ditives used for reactivity enhancement. It has been
theorized that all of the preceding  contribute to such
physical characteristics as surface  area, particle size,
and porosity.  The examination of these physical char-
acteristics  has provided  the basis for understanding
the reaction processes, but has not provided all the
factors necessary to correlate intrinsic sorbent charac-
teristics with reactivity.

rigorous approach than had  been previously taken.
The approach required detailed descriptions of electri-
cal characteristics, electro-hydrodynamics, and charg-

charge showed good  agreement with  experimental
data, indicating that the developed model is capable of
providing good  evaluations  of the  cold pipe  pre-

Treatments (48 h) with highly purified bovine or porcine
inhibins (10 ng/ml) induced ovine pituitary cells to in-
crease their binding for des-Gly(to the tenth power)-(D-
Ala(to the sixth power))LHRH-ethylamide by 3.6- and
5-fold, respectively. Studies with less pure inhibin from
porcine follicles showed that increased binding could
reach 7-fold within 48 h and was due to higher num-
bers of receptors for GnRH. The 48-h increase in
GnRH receptors was linear with time and was rapidly
reversible, since removal of inhibin at 24 h decreased
GnRH binding below control levels at 48 h. Inhibin
(bovine or porcine) also increased GnRH-stimulated
secretion of LH by 2-fold. The ED50 for both inhibin ac-
tions noted above was in the range of 0.5-2.0 ng/ml (in
terms of highly purified bovine inhibin). Progesterone
(P) totally counteracted inhibin induction of GnRH
binding and GnRH-stimulated LH secretion at 48 h.

Identification of DNA adducts in peripheral lympho-
cytes could serve as a means of monitoring human ex-
posure to potential genotoxic agents. In the study,
DNA from peripheral lymphocytes of smokers and
nonsmokers was examined for adducts by the P1 nu-
clease 32p-post-labeling technique. Thin layer chro-
matpgraphy (TLC) maps from both groups revealed
multiple DNA adducts which ranged from no adducts
for one individual to six adducts for a different individ-
ual. The total DNA adduct concentrations were ap-
proximately one adduct in 10 to the seventh-10 to the
eighth power normal nucleotides. Comparison of the
adduct TLC profiles revealed individual variation in
both pattern and level of DNA adducts. The type and
amount of adduct was not influenced by smoking his-
tory and remained unchanged in four out of six sub-
jects who were resampled after a one month interval.
One adduct detected in lymphocyte DNA co-migrated
on TLC with an adduct derived by in vitro incubation of
lymphocytes with benzo(a)pyrene (B(a)P). The 3H-nu-
closide values were consistent with values obtained by
32p-postlabeling of the same sample (correlation coef-
ficient of 0.88). No relationship was apparent between
the capacity of lymphocytes to form a (3H)-B(a)P-de-
rived adduct in vitro and the concentration of the
adduct, or total adducts present in untreated lympho-
cytes.

The neurotoxic effects of long term, low level exposure
to the commercially available insecticide, Fenthion,
were examined in the present study. Young adult, male
long-Evans rats were demally exposed to Fenthion (25
mg/kg, 3X wk.) and sampled after 2 and 10 month ex-
posure to assess neurotoxic damage in the hippocam-
pus using morphological and biochemical endpoints.
Cytopathology, consisting of gliosls and swollen and
necrotic neurons, occurred in the dentate gyrus (DG)
and hilus (CA4) as early as 2 mo. exposure. Acetylcho-
linesterase (AChE) staining of brain tissues taken at
this time was severely reduced in the septal nuclei, the
DG molecular layer, the hilus, and the hippocampus
proper. After 10 mo. exposure to Fenthion, cellular ne-
crosis and glipsis progressed to the CAS regions and
occassionally involved the CA2. Radiometric assays of
AChE activity in the hippocampus indicated a 65% and
85% depression after 2 and 10 mo. exposure, respec-
tively. Quinuclidinldinyl benzilate (QNB) binding for the
hippocampal muscarinic receptor was reduced by 6%
and 15% after 2 and 10 mo. exposure. A separate
group of older (12 mo.) rats were exposed to the same
dosing regimen of Fenthion and examined for neuro-
pathic damage after 2 mo. and 10 mo. exposure. Aged
animals exposed for only 2 mo. expressed severe hip-
pocampal degeneration in a pattern similar to that
seen in the young adult after 10 mo. exposure (viz.,
DG, CA4, CAS). (Copyright (c) 1990 by the Academic

Photoreduction of 2,3,7,8-tetrachlorodibenzo-p-dioxin
(TCDD) to 2,3,7-trichloro-p-dioxin (TrCDD) in isooc-
tane was found to account for approximately 10% of
the loss of TCDD and is thus a minor photolysis path-
way. The remainder undergoes conversion by other
pathways, which may involve carbon-oxygen cleav-
age. One new photoproduct of TCDD, formed by a re-
ductive rearrangement, is 4,4',5,5'-tetrachloro-2,2'-di-
hydroxybiphenyl, as demonstrated by mass spectrom-
etry. Photolysis of TCDD on soils is slow relative to so-
lution photolysis. Organic solvent added to the soil en-
hances the extent of photolysis. Evidence is presented
that transport of TCDD to the surface in the organic
solvent film is primarily responsible for the increased
photolysis, rather than an effect from addition of a re-
ducing hydrogen source. In the unamended soils, pho-
tochemical loss of TCDD was observed only for the
first 5 days of a 15-day irradiation. In soils containing
hexadecane, more than twice the amount of TCDD
was lost, and photochemical loss continued at both 10
and 15 days of irradiation. This observation suggests
that transport of the light-exposed soil/air interface is
occurring. Octachlorodibenzo-p-dioxin (OCDD) under-
goes photoreduction on soil surfaces to the lower
chlorinated congeners. For the pentachloro and tetra-
chloro congeners, the toxic 2,3,7,8-tetrachlorinated
isomers were observed in greater yield than would be
expected on the basis of the number of potential iso-
mers. (Copyright (c) 1990 American Chemical Socie-

A statistical model for describing the distribution of
binding sites in humic substances was developed. The
model was applied to study the spectral titration plot
generated by the lanthanide ion probe spectroscopy
(LIPS) technique. This titration plot is used as a basis
for studying the interactions between metal ions and
humic binding sites. Humic samples were titrated with
Eu(3+), which acts as the fluorescent probe ion. The
competition effects between a proton, a metal ion
other than the probe ion, and the probe ion itself in
binding with the humic binding sites, as well as the
electrostatic effects, are successfully predicted and
described by the model (Copyright (c) 1990 American
Chemical Society.)

Interest among public, governmental, and scientific,
communities about 'global' climatic warming and the
associated meteorological and oceanographic effects,
is a topic of very considerable concern (McElroy, 1989;
Mitchell, 1989). During the past several years, numer-
ous national and international scientific committees
have addressed this problem, as have newspapers
and popular magazines. Government-sponsored legis-
lation, particularly in the United States (for example,
see Wirth, 1989), has been introduced to deal with the
causes of 'global' climate change. Changes in climate
are the norm when one studies the history of the Earth.
These changes include the glacial epochs and the
contemporary climatic variation of the El Nino/South-
ern Oscillation. Examination of palaeoclimatic records
illustrate considerable natural and spatial variability
which makes long-term (20-100 years) forecasting of
climate change highly uncertain. Future climate (and
arguably the present), however, will be influenced by
Man-induced as well as natural processes. Together,
these factors will cause future climate to evolve in un-
certain ways.

trachlorodibenzo-p-dioxin, 2,3,7,8-tetrachlorodibenzo-
furan and polychlorinated biphenyls by marine benthos
exposed to environmentally  contaminated sediment
were measured in a  laboratory study. Sandworms
(Nereis virens), dams (Macoma nasuta) and shrimp
(Palaemonetes pugio) were exposed to sediment from
the  Passaic River, New Jersey for up to 180 days.
Worms accumulated the highest concentrations of
these compounds. Uptake and depuration  rates were

 The utility and limits of applicability of a simple equilib-
 rium partitioning  model for  predicting the maximum
 concentration of neutral organic compounds which
 can be accumulated by infaunal organisms exposed to
 a contaminated sediment were examined. Accumula-
 tion factors (AFs) for PCBs,  the lipid  normalized PCB
 concentration in organisms divided  by the organic
 carbon normalized PCB concentration in  sediments,
 were measured for PCBs in infaunal mollusks and po-
 lychaetes a' field sites with a range of sediment Arc-
 dor (A-1254) and total organic carbon (TOC) concen-
 trations. The average AFs for A-1254 were found to be
 higher (x = 4.94; range 3.76-7.27) at sites with lower
 contaminant concentrations (15.0-48.3 micrograms A-
 1254/g dry sediment) than at more contaminated sites
 (328-9,200 micrograms/g), where AFs were lower (x
 = 2.62; range 1.14-5.04). AF data  grouped on  the
 basis of sediment A-1254 and TOC concentration dif-
 fered statistically between, but not within each group.
 Significant differences in mean AFs were found  be-
 tween  some species and between  some PCB con-
 geners. When all data were considered, the variability
 associated with AFs was tower than that found for
 bioaccumulation factors on a wet weight basis, indicat-
 ing the utility of lipid and organic carbon normalization.

 Chemical  analyses  of  sediment samples  collected
 along a transect in New Bedford Harbor revealed a
gradient of increasing concentrations of polychlorinat-
ed biphenyls (PCBs), polychlorinated  dibenzo-p-diox-
ins (PCDDs), polychlorinated dibenzofurans (PCDFs),
polycyclic aromatic hydrocarbons (PAHs) and several
trace metals from the southern to the northern areas of
the estuary. Although the concentrations of contami-
nants generally increased with  distance  north in the
estuary for all classes of compounds, differences were
observed between the trends for many  of the com-
pounds. These differences are  probably due to both
the sources and differential environmental behaviors
of the compounds in the estuary. (Copyright (c) 1990

The toxicity of fluoranthene in sediment to the marine
benthic  amphipods,  Rhepoxynius abronius (Barnard)
and Corophium spinicome (Stimpson) was determined
 in relation to the equilibrium  partitioning approach to
the development of sediment  quality criteria. Within
the limitations of these experiments  (i.e., one chemi-
 cal, two species, sandy sediment with low carbon con-
tent), the results indicate that sediment quality criteria
 derived  from  the equilibrium partitioning model  and
 water quality criteria would  protect sensitive benthic in-
vertebrates. The epibenthic, tube-dwelling Corophium
 was less sensitive to test sediments than the infaunal,
 free-burrowing Rhepoxynius, possibly because of dif-
 ferent routes of exposure to fluorantnene. There was a
 close correspondence between estimates of sediment
 quality for fluoranthene based on distinctly different
 methodologies including equilibrium  partitioning, ap-
 parent effects threshold, toxicity tests applied to ex-
 perimentally spiked sediment and toxicity tests applied
 to field-collected sediment

 The induction, stimulation, and persistence of sister
 chromatid exchanges (SCE's) and high SCE frequency
 cells (HFC's) was measured in peripheral lymphocytes
 of women with breast cancer before  chemotherapy
 and on multiple occasions during and after therapy.
 Chemotherapy consisted  of i.v. infusion of Cyclophos-
 phamide,  Adriamycin, and 5-fluorouradl, administered
 on day 1 of each of approximately six 21-day cycles.
 This treatment resulted in a highly significant of SCE's
(1.8-fold, P < 0.0001) and HFC's (5-fold, P < O.OOpI)
measured in samples obtained 1 week after the first
therapy. Accumulation of lesions leading to SCE's was
measured by comparing samples surrounding the first
and last rounds of therapy and was significant for both
SCE's and HFC's in most comparisons. Persistence of
lesions leading  to SCE's was evaluated at multiple
times until 9 months after completion of therapy, and
both SCE's and  HFC's remained significantly elevated
throughout this time.

Hamster caput epididymal  spermatozoa  exhibit  a
marked 90-180 degree bend when induced to acquire
progressive motility in vitro (Cornwall et al, 1988). Fla-
gellar bending is prevented by oxidizing sperm sulfhy-
dryl (SH) groups with diamide. In the study, the authors
examined the SH proteins involved in sperm flagellar
bending using two-dimensional polyacrylamide gel
electrophoresis and  monobromobimane, an SH-spe-
cific fluorescent dye. Proteins extracted from samples
containing bent caput  spermatozoa contained more
reduced SH than  the same proteins extracted from
straight caput  spermatozoa. To further characterize
these sperm SH  proteins,  caudal epididymal sper-
 matozoa that exhibited straight flagella were induced
 to undergo  flagellar bending by treatment with the SH
 reductant dithiothreitol.

 A scheme for ranking the quantitative activity of chemi-
 cal carcinogens is  described.  This  activity scheme
 uses as its base, dose potency measured as TD50, the
 chronic dose rate that actuarially  halves the adjusted
 percentage of tumor-free animals at the end of the
 study. The TD50 is converted into an inverse log scale,
 a decile scale, and then adjusted by weighting factors
 that describe other parameters of carcinogenic activi-
 ty. These factors  include positive or  negative weight-
 ings for the induction of tumors at tissues or organs
 associated  with high  historical  control  tumor inci-
 dences; the induction  of tumors at multiple sites; the
  induction of tumors in  both sexes of  the species; and
 the induction  of tumors in more  than one species.
 These factors were chosen as they represented quali-
  tative  descriptions of  the general specificity or non-
  specificity of chemicals with regard to the activity in ro-
  dents and  have some bearing on  the potential activity
  of chemicals in humans. (Copyright (c) 1990 Elsevier

With the growing importance of neurobehayioral as-
sessments at the preliminary stage of chemical test-
ing, it is critical that the screening procedures utilized
be valid indicators of neurobehavioral dysfunction in
addition to being sensitive, specific, and reliable. Ef-
forts in this laboratory have been directed towards as-
sessing these features in the use of a functional obser-
vational battery (FOB). For the purpose of assessing
validity, data collected using the FOB which addresses
the issues of criterion, predictive, concurrent, and con-
struct validity have been examined. It is reported that
the FOB appears to be valid for detecting chemical-in-
duced neurological dysfunction in rats, that is, shows a
good degree of criterion validity. Furthermore, in many
instances the effects observed with the FOB may be
predictive of symptomatology in humans. When com-
parisons can be made between effects detected with
the FOB and other methods of measuring neurotoxi-
city (that is, neuropathology), concurrent validity can
also be established. To assess construct validity, ef-
fects of neurotpxicants can be classified into function-
al domains which are described by the various meas-
ures of the FOB. (Copyright (c) Pergamon Press pic,

TMT is a neurotoxicant known to alter auditory func-
tion. The study was designed to compare TMT-in-
duced auditory dysfunction using behavioral, electro-
physiological, and anatomical techniques. Adult male
Long Evans hooded rats (n=9-12/group) were acutely
exposed to saline, 3, 5, or 7 mg/kg TMT. Auditory
thresholds were determined 11 weeks post-dosing for
5 and 40 kHz tones using reflex modification of the au-
ditory startle response (ASR). Brainstem auditory
evoked response (BAER) thresholds were determined
for 5,40, and 80 kHz tonal stimuli 9 weeks post-dosing.
Cochlear histology was assessed at 13 weeks post-
dosing. Functional endpoints demonstrated a high-fre-
quency hearing loss. ASR thresholds for 40 kHz tones
were elevated 25-35 dB in all dosage groups. BAER
thresholds for 40 and 80 kHz tones were elevated 30-
50 dB in the 5 and 7 mg/kg groups. Organ of Corti sur-
face preparations revealed a pattern of damage sug-
gesting classical ototoxicity. These data demonstrate
the utility of the ASR and BAER in detecting functional
ajterations in audition and indicate that TMT-induced
high-frequency hearing loss is associated with cochle-
ar damage. (Copyright (c) 1990 by Academic Press,

Reflex modification of the acoustic startle response is
a technique that can provide rapid, objective and quan-
titative assessments of sensorimotor function. Advan-
tages of this technique involve the ability to: test ani-
mals rapidly, test without prior training, test without uti-
lizing invasive procedures, and provide objective, inde-
pendent estimates of both sensory and motor func-
tioning. Reflex modification techniques hold great po-
tential for use in neurotoxicology in both the identifica-
tion and the characterization of neurotoxic chemicals.

The effect of hippocampal dynorphin administration on
learning and memory was examined in spatial and
nonspatial tasks. Bilateral infusion of dynorphin A(1-
8)(DYN; 10 or 20 micrograms in one microliter) into the
dorsal hippocampus resulted in dose-related impair-
ment of spatial working memory in a radial maze win-
stay task. Subsequent experiments found that acquisi-
tion of a reference memory task in the water maze was
impaired by DYN injections (20 micrograms/micrpliter)
in the dorsal hippocampus, but not in the ventral hippo-
campus, and that this impairment could be blocked by
naloxone. In a nonspatial task, posttraining DYN injec-
tions in the dorsal hippocampus had no effect on re-
tention of step-through passive avoidance. These re-
sults suggest that dynorphin specifically interferes with
spatial learning and memory, and that this effect is me-
diated by opioid receptors in the dorsal hippocampus.

5-azacytidine (5-aza), a chemical which is incorporated
into DNA and RNA with consequent alterations in the
expression of mammalian genes, was administered to
pregnant Sprague-Dawley rats on single days during
gestation. Doses of 0.5,1, and 2 mg/kg were given by
intraperitoneal injection on days 9,10,11, or 12. Dams
were killed on day 20 of gestation and fetuses were ex-
amined for both external and skeletal defects. 5-aza
affected development on all days tested. The com-
pound was embryolethal, caused reductions in fetal
weight, and had profound effects on morphological de-
velopment. Digit and limb anomalies, exencephaly, mi-
crognathia, gastroschisis, and various rib defects were
observed and related to the day of exposure. (Copy-

Interactions between exposure to xenobiotics and dis-
ease can occur during pregnancy. Few data are avail-
able on the consequences of such interactions on de-
velopmental parameters. In the study we investigated
potential interactions between murine Cytomegalovirus
(MCMV), which induces embryolethality; and sodium
salicylate, a known teratogen. MCMV administered on
day 12 was embryotoxic over a broad range of doses
from 2 times 10 to the third power to 2 times 10 to the
sixth power plaque forming units, and also decreased
postnatal weight gain. MCMV administration on day 8
of gestation caused significant prenatal mortality re-
gardless of salicylate exposure. Salicylate did not
cause fetal mortality or malformations at either 500 or
750 mg/kg/day on days 9 and 10 of gestation. No evi-
dence of synergistic effects of MCMV and salicylate on
embryo/fetal development were seen. (Copyright (c)

The amount of glial fibrillary acidic protein (GFAP), an
astrocyte protein, increases following injury of the
CNS. A radioimmunpassay of GFAP was used to char-
acterize the astrocytic response to injury resulting from
exposure to the dopaminergic neurotoxicant, 1 -methyl-
1,2,3,6-tetrahydropyridine (MPTP). A single adminis-
tration of MPTP to the C57BL/6 mouse resulted in
more than a 3-fold increase in GFAP within 48 hours,
followed by a decline to baseline at 3 weeks. A de-
crease in the amount of tyrosine hydroxylase (TH), a
marker of nigrostriatal dopaminergic neurons, preced-
ed the rise in GFAP. The concentration of DARPP-32,
a phosphoprotein localized to striatal neurons receiv-
ing dopaminergic input, was not affected by MPTP.
Protecting the dopaminergic neurons from the neuro-
toxic metabolite of MPTP, 1 -methyl-4-phenylpyridinium
(MPP+), either by blocking its formation or by prevent-
ing its uptake into dopamine neurons, completely
blocked the increase in GFAP. Blood-borne or brain-
derived interleukin 1 (IL-1), a known astrocyte mitogen,
did not appear to mediate the effects of MPTP on
GFAP. (Copyright (c) 1990 Elsevier Science Publishers

uation was done using laboratory grown human echo-
virus 7, human enterovirus 69 and human poltovirus 1,
plus an  environmental  concentrate derived from
sewage that contained indigenous untyped enterovir-
uses. The cell lines employed were BGM, RD, L-132
and HEL-299. Sequential inoculation generally yielded
higher viral assay tilers when compared with the more
traditional method of simply introducing viral inoculum
onto a culture of the first (initial) cell line and then com-
pleting the assay without  removing that inoculum.
When a permissive cell line (BGM or RD) was used for
both the initial and final cultures in a sequential inocu-
lation technique, the total plaque count liter from both
the initial plus final cultures represented an average
35% improvement over the iraditional method.

 An improved method has been developed for the gly-
 cophorin A  assay for  somatic cell  mutations  in
 humans. The new assay, named Ihe 'BR6' assay, can
 be  performed on  a commercially  available, single-
 beam flow cytometer, in  confrasl to Ihe previously de-
 scribed  1W1 assay that required a dual-beam flow
 sorter. A modified cell labeling meftiod developed for
 the BR6 assay results  in improved separation  of
 normal and mutanl phenotype cells, as well as elimi-
 nating some cellular artifacts thai affected the 1W1
 assay. Parallel measurements on samples from  17
 normal donors showed that the BR6 assay yields com-
 parable variant cell frequencies and improved meas-
 uremenl precision  compared with the  1W1 assay.

  Guidelines for  conducting neurobehavioral tests of
  motor activity,  schedule-controlled operant perform-
  ance  and a functional observational battery (FOB)
  were published by the U.S. EPA Office of Toxic Sub-
  stances (1985). A specific FOB protocol has been uti-
  lized in conjunction with motor  activily measured in a
  figure-eight maze and performance maintained under
  a fixed-interval schedule of reinforcement to determine
  the acute effecls of chemicals which produce differenf
  syndromes of intoxication in rals (chlordimefomn, car-
  baryl pentobarbital, triadimefon, nicotine, and 3-acetyl
  pyridine). In all cases, the lowest effective dose identi-
  fied using the FOB was equal to or less than thai pro-
  vided by motor activity and operant tests. For most
   compounds, motor activity and operant performance
   were equally sensitive. Nicotine and triadimefon, how-
   ever  increased  the rate of operant responding at
   doses lower than those required to affect motor activi-
   ty The time course of each chemical appeared similar
   across tesls with one exception. 3-Acetyt pyridine pro-
   duced clear effecls in Ihe FOB throughout testing (up
   to 3 weeks) whereas recovery  was evident within one
   week using motor activity and operant performance.

The paper gives  results of an exploratory sludy to
assess Ihe semivolatile and nonvolatile organic-pollut-
ant emission  rates  from  unvented  kerosene space
heaters. A well-tuned radiant heater and a martuned
convective heater were  tested for  semivolatile and
nonvolatile organic pollutant emissions. Each healer
was operaled In a 27 cu m chamber with a prescribed
on/off pattern. Organic compounds were collected on
Teflon-impregnated glass-fiber filters backed  by XAD-
 2 resin and analyzed by gas chromalography/mass
 speclromelry. Pollutant source strengths were calcu-
 lated  using a mass-balance equation. The results
 show thai kerosene  heaters can emit polycyclic aro-
 matic hydrocarbons (PAHs); nitrated PAHs; alkyl ben-
 zenes; phthalates;  hydronaphlhalenes; aliphatic  hy-
 drocarbons, alcohols, and ketones; and other organic
 compounds, some  of which are known  mutagens.

  During an evaluation of field portable gas chromato-
  graphs (GC), site-specific performance evaluation ma-
  terials (PEM) were prepared and used as quality con-
  trol samples. Clean soils from  two contaminated  sties
  were spiked with various volatile organic compounds.
  The PEM were shipped to the field via air carrier and
  analyzed by GC. The PEM samples were also shipped
  back to Ihe  laboratory  and analyzed as double  blind
  samples on a GC and a gas chromatograph/mass
  spectrometer (GC/MS).  PEM samples which  were
  held in the laboratory without being shipped were also
  analyzed. For GC analyses a static headspace method
  revealed highly variable recoveries for both shipped
  and  unshipped PEM. An operationally-defined head-
  space calibration was used to quantitate the amount of
  analyte remaining in Ihe soil al various holding times
   and under various shipment scenarios. The influence
   of soil characteristics and volatile compound proper-
   ties, and the effecls of holding time and shipping on
   analyle stability in actual and spiked soils are dis-
   cussed. (Copyright (c) 1990 by Marcel Dekker, Inc.)

A collision-induced dissociation (CID) sludy of five syn-
thesized nitramines was carried oul using a hybrid
EBQQ mass spectrometer. CID spectra were obtained
in two  modes:  B/E linked-scan mode and MS/MS
mode using Ihe EB sector combination as the first
mass spectrometer and  Ihe QQ as collision cell and
second mass spectrometer, respectively. Fragmenta-
tion pathways of Ihe compounds were  determined in
Ihe elertron-impacl mode. It was found that dominant
fragmentation pathways included the loss of OH NO2
 and HNO2  in addition to Ihe loss of CH2NNO and
 CH2NNO2.  (Copyrighl (c) 1990 by John  Wiley and

examination of the apparent concentration efficien-
cies, as well as the behavior of two internal standard
elements added to the eluate stream, indicates that
the elution front matrix enhances the inductively cou-

suggests that the detection limits of several of the iso-
topes could benefit by much larger preconcentration
factors, while those of vanadium, copper, cadmium,

oratory contamination. The preconcentration system is
evaluated on several simple synthetic matrices, as well

Thermospray ionization with repeller-induced collision-
ally activated dissociation (repeller-CAD) has been
used to acquire mass spectra of a series of dyes.
These were obtained by applying a voltage of 400 V on
the wire repeller. The mass spectra contained a large
number of fragment ions which were useful for struc-
tural elucidation. Some of these fragment ions were
found to be similar to those obtained by thermospray
tandem mass spectrometry with CAD and some of
them were similar to those obtained by electron ioniza-
tion using a particle beam liquid chromatrography/
mass spectrometry interface. The results indicate that
more than one mechanism is involved in the fragmen-
tation process. (Copyright (c) John Wiley and Sons

tively rural environmental conditions within Research
Triangle Park, N.C. The study was designed to deter-
mine how various environmental factors contribute to
the rate of soiling of white painted surfaces. Significant
factors that were monitored were hourly rainfall and
wind speed, and weekly data for dichotomous sampler
measurements and total suspended matter concentra-
tions. Gloss and flat white paints on hardboard were
exposed vertically and horizontally, both protected and
unprotected from rain for 16 weeks. Measurements of
exposed samples were taken at two, four, eight, and
16 weeks. Reflectance was measured and scanning
electron microscopy (SEM) stubs, which had been
flush-mounted into the hardboard prior to painting,
were removed at these times. Particle size distribu-
tions were determined by scanning electron microsco-
py. (Copyright (c) 1990 Elsevier Science Publishing

A thermal modulator that can act as an interface be-
tween supercritical fluid extraction and supercritical
fluid chromatography was developed and tested. The
modulator was made of a short segment of a fused-
silica capillary column, which was coated on the out-
side with electrically conductive paint so that it could
be heated rapidly by a pulse of electric current. An
equivalent of an injection is made internally within a
flowing stream containing the sample by alternately
heating and cooling the modulator, rather than by in-
troduction through an injection port or a valve.

Analytical solutions are developed for the Richards'
equation following the analysis of Broadbridge and
White. Included here is the solution for drainage and
redistribution of a partially or deeply wetted profile. Ad-
ditionally, infiltration for various initial conditions is ex-
amined as well as evaporation at the upper boundary.
In all cases the surface flux is constant, whether it be
zero for drainage, positive for infiltration, or negative
for evaporation. The solutions assume specific forms
for the soil water diffusivity and hydraulic conductivity
functions: a(b - theta) sup (-2) and beta + gamma(b -
theta) + lambda/(2(b - theta)), respectively. Here
theta is the water content and a, b, gamma, and
lambda are constants. (Copyright (c) 1990 by the

A fluorescence-quenching method was developed to
assess the hydrophobic organic pollutant binding po-
tential of organic colloids (OC) in unaltered natural
waters. This method allows direct assessment of the
importance of OC-enhanced pollutant transport for en-
vironmental samples under in situ water chemistry
conditions, without requiring the isolation of OC or sep-
aration of equilibrated phases; testing of chemicals
that surfer substantial wall losses from aqueous solu-
tions; and examination of unstable water samples such
as anoxic samples. The experiments show that some
OC (Aldrich humic acids) fully quench OC-associated
perylene fluorescence, but others (bovine serum albu-
min) do not. This implies that fluorescence-quenching
results collected for a single (OC) or over a limited
(OC) range provide only a lower limit estimate of the
potential for OC association. Tests with groundwater,
recharged with secondarily treated sewage and con-
taining OC at concentrations of about 1 mg of C/L,
showed temporal variation in the ability of OC present
to quench or bind perylene. (Copyright (c) by the Amer-

A two-dimensional finite-element model was devel-
oped to predict coupled transient flow and multicom-
ponent transport of organic chemicals which can parti-
tion between NAPL, water, gas and solid phases in
porous media under the assumption of local chemical
equilibrium. Gas-phase pressure gradients are as-
sumed negligible and liquid flow equations are solved
simultaneously using an upstream weighted solution
method with time lagged interphase mass-transfer
terms and phase densities. Phase-summed compo-
nent transport equations are solved serially after com-
putation of the velocity field also by an upstream
weighted finite-element method. Mass-transfer rates
are evaluated from individual phase transport equa-
tions by back-substitution and corrected for mass-bal-
ance errors. Results of hypothetical simulations of the
transport of slightly soluble and volatile organics in
three-phase porous media indicate that mass-transfer
rate and fluid density updating have negligible effects
during periods of highly transient NAPL migration but
become important for long-term simulations. Due to
low solubilities of environmentally important organic
liquids, the efficiency of organic removal by aqueous-
phase dissolution and transport can be very slow. Gas-
phase diffusion can have a significant influence on the
mass transport of organics with large Henry's con-
stant. (Copyright (c) 1990 Elsevier Science Publishers

The 3-week  exposure of a branch of a forest-grown
red spruce (Picea rubens) sapling to the  combination
of gaseous hydrogen peroxide, ozone, and sulfur diox-
ide is reported on. The exposure was conducted con-
tinuously using concentrations of H2O2, O3, and SO2
that have been observed during the  summertime on
the summit of Whiteface  Mountain, New York. Fluxes
of H20,  CO2, and the three pollutants  were deter-
mined throughout the exposure. At weekly intervals,
measurements of chlorophyll fluorescence, stomatal
conductance, and hydrocarbon emissions were made.
The response of the branch  was compared to an
equivalent branch of the same tree which received no
pollutants but was otherwise treated identically.  The
exposure produced no visible injury symptoms but did
produce an increase in dark respiration; the respiration
rate more than doubled  during the 21-day exposure
period. Net  photosynthesis was unaffected for both
the experimental and the control branches. Nighttime
fluxes of SO2 and H2O2 to external plant surfaces
were  significant.  The stomatal  component of O3
uptake by the branch displayed a linear increase
during the experiment, and showed no  evidence of
saturating. Daytime and nighttime fluxes of H2O2 were
increasing at the end of the  experiment. Itwas ob-
served that  isoprene is emitted from red spruce, but
saw no clear-cut change in emission rate in response
to the exposure experiment.

 The authors  describe an experimental system and
 techniques for use in simultaneous pollutant exposure
 experiments and gaseous flux  determinations. The
 system  uses flexible Teflon bag-like chambers to en-
 close entire individual  branches of young trees. Five
 gaseous fluxes (CO2, H2O, SO2, O3, and H2O2) are
 measured once per hour for each of two branches.
 Techniques for determining chamber surface loss cor-
 rections and  methods of estimating needle surface
 area of conifers are described. A three-week continu-
 ous test was run in order to evaluate system perform-
 ance. Inlet concentrations of the five gases were ex-
 tremely stable, with uncertainties  of <2.2%  in all
 cases and day-to-night differences of <4%. Compari-
 son of two branch chambers, one with clean air and
 one with the added pollutant gases H2O2, SO2, and
 O3, showed that between-chamber differences were
 <2% for the average inlet concentrations of H2p and
 CO2. Pollutant losses to chamber surfaces were  signif-
 icant but were generally  smaller than losses to the
 branch itself. Chamber loss corrections were different
 for daytime and nighttime conditions and also evolved
 as the three-week experiment proceeded.

Studies  have  been conducted  to  obtain practical
knowledge regarding the stability, digestion, and ana-
lytical determination of the content of 8-hydroxy-2-
deoxyguanosine (8-OHdG) in oxidatively damaged
DNA. Utilizing H2O2 plus UV light to form oxidatively
damaged DNA, the authors found that storage of the
DNA at -20C at alkaline pH caused a significant loss of
8-OHdG, whereas storage at -20C at neutral or acidic
pH  prevented loss of 8-OHdG. The 8-OHdG within
DNA is stable at 10OC for at least 15 min. Formation of
8-OHdG within DNA using UV light and H2O2 as a hy-
droxyl free radical-generating system yields the high-
est amounts when low levels of phosphate buffer are
used; but the use of Tris or citrate buffers cause a
lower yield  of 8-OHdG because these buffers act as
scavengers for the hydroxyl free radicals. Independent
assessment of hydroxyl free radical flux by the use of
salicylate trapping allows assessment of competitive
radical reactions. (Copyright (c) 1990 Academic Press,

The paper will focus on the demonstration of hazard-
ous waste cleanup technologies in the field. The tech-
nologies will be at the pilot- or full-scale, and further re-
ferred to as field-scale. The main objectives of demon-
stration at the field-scale are development of reliable
performance and cost data. Technology demonstra-
tions provide performance, cost effectiveness, and re-
liability data so that potential technology users have
sufficient information to make effective decisions as to
the applicability of the technology to  a specific situa-
tion. The demonstration and evaluation of a technolo-
gy should be conducted with the purpose of character-
izing performance, need for pre- and  post-processing
of the waste feed, identification of waste type an con-
stituents applicable to the technology,  system through-
put, problems and limitations of the technology, and
operating and maintenance  costs. Table I provides a

 Brown cells of the red gland in Mercenaria mercenaria
 are involved in the excretory process. Their involve-
ment in the removal of foreign substances from the tis-
sues of Mercenaria was studied. Toluidine blue (solu-
ble dye) accumulated in brown cells after dye injection
into the foot muscle and after addition to brown cell
isolates. In comparison, carmine red (paniculate dye)
did not accumulate under the same conditions. FITC-
labeled bovine albumen accumulated in  brown cells
when introduced in vivo and to cell isolates. Kinetic
studies indicated uptake of FITC-albumen occurred
within 2 h when added to cell isolates and within 24 h
after injection into the foot muscle. Brown cell isolates
were separated into three fractions on a discontinuous
Percoll gradient.  Fraction 1  contained primarijy what
appeared to be precursor brown cells. The majority of
the cells in fraction 2 were brown cells. Fraction 3 was
entirely brown globular material. Assays indicated the
presence of acid phosphatase, glutathione reductase
and lysozyme in lysates from each fraction. Thus it ap-
pears that brown cells of the  red gland contain en-
zymes involved in detoxification and degradative proc-
esses. (Copyright (c) 1990 Elsevier Science Publishers

macro-algae  were developed. Copper sulfate and
sodium dodecyl sulfate were used as representative
toxicants. Coefficients  of variation for LC50 results
ranged from 1.8 to 46.4%. The precision obtained is
comparable to other toxicity tests, but it is uncertain
whether the precision of such tests in general  is ac-

 Adenylate  energy charge  is an  indication  of  the
 amount of  energy available to an organism from the
 adenylate pool. It is calculated from measured concen-
 trations of  three adenine nucleotides, adenosine tri-
 phosphate  (ATP), adenosine diphosphate (ADP) and
 adenosine  monophosphate (AMP), which are integral
 to the energy metabolism of all organisms  (Atkinson
 1977). The AEC, defined as (ATP + 1/2 ADP)/ (ATP
 -I- ADP + AMP), has a maximum value of 1.0 when all
 adenylate is in the form of ATP and a minimum value of
 0 when all  adenylate is in the form of AMP  (Atkinson
 and Walton  1967). Therefore, a knowledge of  the
 energy charge of key species with known responses to
 particular environmental conditions may provide a con-
 venient measure to assess the extent to which these
 species are stressed. Sediment from a relatively clean
 site in Long Island Sound and a highly contaminated
 sediment from Black Rock Harbor, Connecticut which
 contained  high concentrations of PCBs, PAHs and
 some metals were used to determine if any observable
 stressful effect, as indicated by AEC, was due to the
 physical action of the  suspended material rather than
 to a toxic compound.

Initial attempts at measuring AEC in Nephtys incisa
yielded low values. A low energy charge most likely in-
dicates a poor extraction of adenine nucleotides in
tissue samples from individuals collected from a nonli-
miting environment. Thus, there was a need to develop
an extraction and handling procedure for N. incisa that
consistently produced values for AEC ratios that were
representative of in vivo values reported for actively
metabolizing cells, (Atkinson 1977). The objective of
the study was to evaluate the applicability of AEC as a
measure of stress in N. incisa treated with dredged
material under laboratory conditions and to determine
the degree of variability inherent in the test.

The biological potency (relative to 2,3,7,8,-tetrachloro-
dibenzo-p-dioxin, TCDD) of planar polychlorinated aro-
matic hydrocarbons (PCHs) in extracts of eggs and
flesh from spawning female Chinook salmon (Oncor-
hynchus tschawytscha) from Lake Michigan was de-
termined by measuring the induction of 7-ethoxyresor-
ufin O-deethylase activity in H-4-II-E rat hepatoma
cells. TCDD-equivalents in flesh and egg samples
ranged from 0 to 115.8pg/g, and were approximately
5-fold greater in eggs than in flesh. These results sug-
gest that the maternal transfer of PCHs may play a role
in determining the reproductive success of Lake Michi-
gan Chinook salmon. (Copyright (c) 1990 Elsevier Sci-

Using a preparation of highly purified, adult rat Leydig
cells and conditions of culture which was found to opti-
mize testosterone production during 24 h, attempts
were made to maintain optimal testosterone produc-
tion for 3 d. Leydig cells cultured on Cytodex 3 beads
at 19% O2 in Dulbecco's modified Eagle's medium-
Ham's nutrient mixture F12 (1:1; vol/vol) containing
0.5 mg/ml total bovine lipoproteins (< 1.222g/ml) with
maximal luteinizing hormone (LH) stimulation failed to
maintain a constant amount of testosterone for 3 d.
These cells did however secrete a similar amount of
total delta 4-3-ketqsteroids on each of the 3 culture d,
indicating that their viability was preserved. The pre-
dominance of progesterone and 170H-progesterone
relative to the amount of androstenedione found on
Days 2 and 3 suggested that the activity of the cytoch-
rome P450C17-hydroxylase-C17,20-lyase enzyme in
the smooth endoplasmic reticulum was diminished
when Leydig cells were maintained in our primary cul-
ture for longer than 24 h. Decreasing the oxygen ten-
sion of the cultures from 19 to 5%, and decreasing the
concentration of LH used to stimulate the Leydig cells
from 100 to 0.1 ng/ml, were necessary to achieve
maintenance of testosterone secretion without accu-
mulation of other delta 4-3-ketosteroids during a 3-d
period. Cells cultured in this fashion were still able to
respond to maximal LH stimulation during Day 3, pro-
ducing as much testosterone as if cultured for 24 h on
Day 1 at 19% O2 with 100 ng/ml LH stimulation.

The report evaluates a method to detect conjugal DNA
plasmid transfer in soil slurries under various environ-
mental conditions. Donor Pseudomonas cepacia con-
taining pR388::Tn1721 and P. cepacia recipient cul-
tures were co-incubated in soil slurries containing au-
toclaved or natural soil and treated with one or more of
14 experimental conditions. Conjugal mating frequen-
cy (transconjugants per initial donor) ranged from 4.8 X
ten to the minus 1 to 1.9 X ten to the minus seventh.
Highest numbers of transconjugants, 1.5 X ten to the
seventh colony forming units/ml soil slurry, were ob-
served following incubation at 35C with an enriched
nutrient supplement added to the soil. Low numbers of
transconjugants, ten to the third colony forming units/
ml soil slurry, were observed when mating pairs were
subjected to low nutrient or pH stress even though ini-
tial donor and recipient populations were maintained at
high levels. The test system provides a simple way to
estimate effects of changing environmental factors on
plasmid transfer rates and on the survival of recombi-
nant microorganisms. By use of soil collected from
sites proposed to receive genetically engineered
microorganisms, preliminary risk assessments can be
obtained regarding the potential for gene transfer and
microorganism survival with this soil slurry test system.

From 270 published laboratory airborne death rate
measurements, two regression models relating the
death rate constant for 15 bacterial species to aerosol
age in the dark, Gram reaction, temperature, and an
evaporation factor which is a function of RH and tem-
perature were obtained. The independent variables
accounted for 94% of the variation in the data for each
of the two models. In both models the regression
shows an increased survival rate with aerosol age ac-
counting for approximately 90% of the total variation in
the data. The remainder of the total variation was ex-
plained by temperature and RH (in interaction with the
Gram reaction) in one model and by the evaporation
function (in interaction with the Gram reaction) in the
other model. Death rate data for gaseous atmospheric
contamination, and light experiments were too few for
building a regression model. In addition, these points
were not well fit by the model indicating further re-
search is needed to prepare realistic prediction models
for airborne bacterial survival.

Exposures to low levels of O3 cause epithelial and in-
terstitial injury in the proximal alveolar region. The se-
quential development of this lesion caused by a simu-
lated ambient pattern of O3 was studied by exposing
Fisher 344 rats to O.OSppm O3 overnight with an 8 hr
daytime exposure having a slow increase to a peak of
0.25 ppm and then gradually decreasing back to 0.06
ppm. Animals were studied using EM morphometric
techniques after 7, 21 and 90 days exposure as well as
post 90 days exposures. The early changes in O3 ex-
posed animals included increases of volumes in type II
epithelium (60%), type I epithelium (16%), cellular in-
terstitium (52%), non-cell interstitium (33%), and in al-
veolar macrophages (180%). The response showed a
biphasic reaction with the early injury subsiding after
21 days of O3 exposure. The animals exposed for 90
days showed a 28% increase in relative volume of
type I and a 42% increase in type II epithelia.

Recent studies have demonstrated that in the absence
of spleen function, frequencies of micronuclei (Howell-
Jolly bodies) in peripheral rbcs can be used to meas-
ure in vivo cytogenetic damage. Among 20 subjects
studied 6 months after splenectomy,  1 had a frequen-
cy of micronucleated rbcs more than  an order of mag-
nitude higher than rates for the others. Initial data sug-
gested that this subject was  mildly folate-depleted,
and a therapeutic trial with  folate rapidly reduced the
frequency  of micronucleated rbcs to normal values.
These observations suggest a need to evaluate further
the contribution of  mild levels of folate depletion to
spontaneous  chromosomal damage. The approach
used here provides a sensitive index of clastogenic
damage and offers unique opportunities for investigat-
ing the determinants  of   cytogenetic  damage in
humans.

Studies of rotavirus challenge in adult volunteers made
it possible to evaluate the relationship  of preexisting
anti-rotavirus fecal IgA antibody to infection and illness
and to investigate the local response to this infection.
No relationship could be found between the preexist-
ing levels  of fecal anti-rotavirus IgA antibody and pro-
tection from infection or illness. A >  6-fpld increase in
the level of antibody was seen in 16/19 infected volun-
teers with  determinable increases but not in 0/15 con-
trols who  received  less than the minimal infectious
dose of rotavirus. Antibody levels increased rapidly in
infected volunteers and were consistent with an anam-
nestic response. Two of seven volunteers who re-
ceived an  infectious dose of rotavirus but were consid-
ered uninfected on the basis of other laboratory meth-
ods had greater than or equal to 6-fold rises of fecal
antibody and  one of these experienced symptoms
compatible with a rotavirus infection. This finding indi-
cates that an increase in fecal antibody may be a reli-
able indicator of rotavirus infection even in the ab-
sence  of  detectable shedding or seroconversion.

 Groups of rats and guinea pigs with normal lungs and
 others  with  elastase-induced  emphysema were ex-
 posed to  NH4NO2 aerosols of 0.60  MMAD at 1 mg/cu
 m for 6 hr/day, 5 days/wk for 4 wks. Morphologic and
 morphometric  studies were performed on lungs per-
 fused  with cacodylate-buffered  2%  glutaraldehyde
 under 20 cm H2O pressure at necropsy. The tissues
 were studied for pathologic change by light microscop-
 ic methods, including changes in mean alveolar chord
 length, using  scanning electron microscopy (SEM)
 techniques.  Elastase produced emphysema to  a
degree quantifiable by all criteria studied; however, it
apparently obscured the effects of nitrate inhalation.
The  NH4NO3 exposures (compared to air  alone)
tended to increase values for pulmonary parameters in
normal animals of both species and to decrease them
in  elastase-treated  animals.  The   responses  to
NH4NO3 were slight (P  <  0.10) and were not accom-
panied by any detectable  changes in alveolar struc-
ture. Therefore, the effects of NH4NO3, at this expo-
sure level and duration, are regarded as biologically in-
significant for rats and guinea pigs. (Copyright (c) by

The report documents the development of the 1985
NAPAP Modelers' Emissions Inventory, Version 2. The
inventory  includes emissions  estimates of air pollut-
ants that play a key role in the formation of acidic dep-
osition. Emissions estimates from all of the major an-
thropogenic sources  of acid deposition precursors in
the U.S. and Canada for the base year 1985 are includ-
ed in  the  inventory.  Natural  sources of particulate
matter are also included. The inventory emissions total
approximately 27.2 million tons per year (tpy) of SO2,
22.6 million tpy of NOx, and 24.5 million tpy of VOC.
The report discusses the data collection and quality
assurance activities associated with the development
of both the annual emissions inventory and an invento-
ry that has been resolved into an hourly, gridded, and
speciated format suitable for use in atmospheric mod-
eling. The file formats and file  structure of the invento-

Lake Le-Aqua-Na is a 39.5 acre (16.0 ha) recreational
impoundment located  in Le-Aqua-Na State Park, Ste-
phenson County, Illinois. The lake is owned and man-
aged  by  the Illinois  Department  of Conservation
(IDOC). A Phase  I diagnostic/feasibility  study, con-
ducted in 1981 under the Federal Clean Lakes Pro-
gram identified the following major  problems  in the
lake: high nutrient levels, nuisance algal blooms, ex-
cessive aquatic macrophytes, hypolimnetic oxygen de-
pletion, and high turbidity and sedimentation. A man-
agement plan was recommended which included aer-
ation/destratification, macrophyte harvesting, periodic
algal treatment, and watershed treatment.  The plan
was implemented and intensive monitoring of the lake
and tributaries was conducted  by the Illinois Environ-
 mental Protection  Agency with funding provided by a
 National Agricultural Conservation Program Special, a
 State ACP Special, and a Clean Lakes Phase II grant
from  the United  States  Environmental  Protection
 Agency.

 Dioxins and Related Compounds is a revised interim
 procedure for estimating the risks considered with ex-
 posures to  mixtures of dioxins and furans such as in-

The report  summarizes previous research conducted
by  Lowry Engineering, Inc. (LEI),  the Maine  Depart-
ment of Human Services, Division of Health Engineer-
ing, and the University of Maine, Department of civil
Engineering, on the removal of  Rn  from drinking water
supplies using granular activated carbon (GAC) in 121
point-of-entry (POE) applications. The primary focus of
the work was an analysis of the  existing treatment data
collected over the past seven years at POE locations
in 12 states. All but three systems treated private hou-
sehuLd well supplies. In addition, two schools and one
public water supply  were included. In summary, the
POE GAC treatment was very effective, with the ex-
ception of approximately 6 percent of the units that ex-
hibited diminishing effectiveness over time. Ninety-four
and 84 percent of all units exceeded 90 and 95 per-
cent  removal,  respectively. The  need for  gamma
shielding was evaluated and related to the raw water
Rn level treated by the POE devices. While POE GAC
installations were found to be effective,  the use of
GAC  for Rn removal may be  limited  in the future to
wells containing less than 5,000 to 10,000 pCi/L This
would result if the private residence desired to achieve
the new MCL for Rn, which is  expected to be set be-
tween 200 and 2,000 pCi/L

 The report gives results of an evaluation of paniculate
 emission trends for three models of catalytic and two
 models of non-catalytic woodstoves under 'in-home'
 burning conditions during the 1988-89 heating season
 in  Glens Falls,  NY. The results (averaging 9.4 g/h and
 9.4 g/kg) showed about a 55% reduction  in emissions
 compared to  conventional woodstoves and demon-
 strate that the emissions performance of new wood-
 stove technologies has improved compared to that  of
 stoves in earlier field studies. Emissions  for the non-
 catalytic stoves were about 50-55%  and for the best
 performing catalytic stove about  80% lower than the
 conventional  wood-stoves.   Two of  the  catalytic
 models displayed elevated emissions; in one, a signifi-
 cant degradation trend developed; and in the other,
 emissions were elevated throughout the test period.
 Leaky bypass systems appear to be a major cause, as
 well  as catalyst  deterioration resulting from lack  of
 flame shielding and inadequate air/fuel mixing. Field
 emissions exceed laboratory certification values on av-
erage by 2.5 times, but the ratio varies considerably
among the stove models. Causes of these discrepan-
cies include quality control problems with tolerances in
production stoves, emissions deterioration over time,
and inadequacies in stove design introduced as the
result of attempts to design stoves for conditions other
than met in the field.

 The Waste Reduction Evaluation  at Federal Sites
 (WREAFS) Program consists of a series of demonstra-
 tion and  evaluation projects for waste reduction con-
 ducted cooperatively by EPA and various parts of the
 Department of Defense (DOD), Department of Energy
 (DOE), and other Federal agencies. The objectives of
 the WREAFS Program  include: (1) conducting waste
 minimization workshops; (2) performing waste minimi-
 zation  opportunity assessments;  (3) demonstrating
 waste minimization techniques or technologies at Fed-
 eral facilities; and  (4) enhancing waste minimization
 benefits  within the Federal community. One of the
 WREAF sites chosen for performance of a waste re-
 duction assessment is the Philadelphia Naval Shipyard
 (PNSY). This Federal facility specializes in revitalizing
 and repairing ships already in fleet. A wide range of in-
 dustrial processes are performed at the PNSY, many
 of which generate wastes. The project focused on the
 processes and wastes of operations related to alumi-
 num cleaning,  spray painting,  and bilge  cleaning.
 Seven waste  minimization options were evaluated
 during the project using EPA's Waste Minimization Op-
 portunity Assessment Manual.

The report gives a complete classification of all materi-
als used in  the  construction of, or brought  inside,
homes and office buildings. In the classification tables
presented in the report, shaded  entries are potential
sources of indoor  air  emissions. The classification
system is based on the U.S. Census of Manufacture's
Standard Industrial Codes (SICs). A comprehensive
list of all products found in buildings is presented which
demonstrates that materials can  be classified using a
uniform methodology for systematic evaluation as po-
tential indoor air pollution sources. Another document
is planned which would include more complete infor-
mation on the materials which are shown here as po-
tential sources of indoor air emissions.

A study of the relationship between water quality at the
consumer's taps and the corrosion of lead solder was
conducted  under actual field conditions in 90 homes
supplied by public water in the South Huntington Water
District  (New York) and at 14 houses supplied by pri-
vate wells  in Suffolk  County on  Long Island  (New
York). The study was done in three phases three differ-
ent pH ranges (5.0-6.8, 7.0-7.4, and 8.0 and greater).
The phase  I study was preformed without any pH ad-
justments on the water sources. Phase II and III stud-
ies consisted of raising the pH by the addition of caus-
tic soda and maintaining pH for thirty days prior to the
sampling. After an overnight period of nonuse, a series
of samples were collected at specific time  intervals to
evaluate the effect of time on the leaching rate of lead.
Data  were collected on  leaching  of cadmium and
copper and water quality parameters were monitored.
In the 2nd part of the investigation, a more controlled,
four-pipe loop study was conducted with the same cor-
rosive Long Island water. Each pipe loop consisted of
approximately 60 feet of  copper pipe with 22  solder
joints, each loop having a different type of solder:  (1)
tin/lead; (2) tin/antimony; (3) silver/copper, and  (4)
tin/copper.  The four loop solder test results indicate
the tin/antimony, silver/copper, and tin/copper can be
used with only minor metal leaching.

The  Hazardous  and  Solid Waste  Amendments
(HSWA) to the Resource Conservation and Recovery
Act (RCRA)  include specific provisions restricting the
land disposal of  RCRA hazardous wastes. The pur-
pose of these HSWA provisions is to minimize the po-
tential of future risk to human health and the environ-
ment by requiring treatment of hazardous wastes prior
to their land disposal. The EPA's Office of Research
and Development was responsible for treating several
electroplating and metal-finishing waste codes and
providing performance data in support of the develop-
ment of treatment standards for the Land Disposal Re-
strictions Program. The report summarizes the project
activities  associated with the characterization and
treatment of some metal-finishing wastes. Information
and data are presented on the waste generators' man-
ufacturing and wastewater treatment plant operations,
the chemical composition of the untreated wastes, and
performance data generated from bench- and pilot-
scale testing. Treatment technologies discussed in the
report include alkaline  chlorination, wet-air oxidation,
ultraviolet light/ozonation, electrolytic oxidation, stabi-
lization/solidification, and  metals  precipitation. Con-
clusions are presented regarding the effectiveness of
the various technolpgies in treating selected electro-
plating  and  metal-finishing wastes. The report  also
presents a section on cyanide chemistry. Most of the
wastes discussed in the report contain cyanide salts or
complexed cyanide; therefore, the section provides a
background of useful information on terminology, defi-
nitions, cyanide chemistry, stability and toxicity of cya-
nide compounds, and analytical methodologies.  An

 The research study examined the effectiveness of dry
 vacuuming and wet cleaning for the removal of asbes-
 tos fibers from carpet, and evaluated the potential for
 fiber  reentrainment during carpet  cleaning  activities.
 Routine carpet cleaning operations using high-efficien-
 cy paniculate  absolute  (HEPA) filtered dry vacuum
 cleaners and HEPA-filtered hot-water extraction clean-
 ers were simulated on carpet artificially contaminated
 with asbestos fibers. Overall, wet cleaning the carpet
 with a hot-water extraction cleaner reduced the level
 of asbestos contamination by approximately 70 per-
 cent. There was no significant evidence of either an in-
 crease or a decrease in asbestos concentration after
 dry vacuuming. The level of asbestos contamination
 had no significant effect on the difference between the
 asbestos concentrations before and after cleaning.
 Airborne asbestos concentrations were  two to four
 times greater during the carpet cleaning activities. The
 level of asbestos contamination in the carpet and the
 type of cleaning method used had no significant effect
 on the difference between the airborne asbestos con-
 centration before and during cleaning.

The U.S. Environmental Protection Agency (EPA) has
completed its five-year National Survey of Pesticides in
prinking Water Wells (the Survey or NPS). The survey
is the first and perhaps the most extensive monitoring
survey ever undertaken to evaluate the presence of
pesticides, pesticide degradates, and nitrate in drink-
ing water wells in the United States. EPA's Phase I
Report provides national estimates of the occurrence
and frequency of detections of nitrate and pesticides in
drinking water wells. The Phase I results of the Survey
indicate that at least half of the nation's drinking water
wells contain detectable amounts of nitrate, with a
small percentage of concentrations higher than EPA's
regulatory and health-based limits for drinking water
(about 1.2% of community water system (CWS) wells
and about 2.4% of rural domestic wells).

Under Section 313 of the Emergency Planning and
Community Right-to-Know Act, also known as the
Toxics Release Inventory, certain manufacturers are
required to submit reports each year on the amounts of
chemicals their facilities release into the environment,
either routinely or as a result of accidents. The purpose
of this reporting requirement is to inform government
officials and the public about releases of toxic chemi-
cals into the environment. Section 313 requires facili-
ties to report releases to air, water and land. The report
presents Toxic Release Inventory data from the 1989
and 1988 reporting years for EPA Region 10 which

The Pacific Northwest is in the midst of a dramatic
change in the way municipal solid waste disposal serv-
ices are provided to residents. Increased environmen-
tal and public concerns, as well as increasing costs for
proper waste disposal, are causing the traditional local
landfill to be replaced by large, regional, often private-
ly-owned disposal facilities. The report presents a brief
description of waste movement and the regionalization
trend in the Pacific Northwest states. It then presents
the policy and cost and benefit implications for Jurisdic-
tions which are considering importing or exporting
waste. Although regional facilities can provide eco-
nomically efficient and environmentally sound waste
disposal, policy makers need to compete balancing in-
terests in determining whether waste exportation or
importation is sound. Costs, the availability of bac k-up
facilities, the potential for disruption in the transporta-
tion network, being a 'good neighbor, environmental
impact to the en-route and receiving jurisdictions, etc.
are all important considerations. In addition, impact on
future and existing recycling programs must be evalu-
ated. Finally, policy-makers considering restrictions or
fees on importation of solid waste must also balance
the policy and legal issues of trying to encourage or
discourage solid waste from coming into their jurisdic-
tion. Finally, jurisdictions can be most effective in ad-
dressing these issues by working together to ensure
sound practices throughout the region in which the
public interest is protected.

Annual load estimates of twelve parameters from
seven Michigan tributaries were calculated from 1984
to 1986. Estimates were calculated by dividing sample
concentrations into high and low strata and applying
Beale's Ratio Estimator. The greatest annual loads of
the twelve parameters usually came from the St.
Joseph followed by the Black or Rouge rivers and the
lowest annual loads came from either the Pere Mar-
quette or Ontonagon rivers. Moi.te Carlo studies indi-
cate that flow stratified sampling strategies yield unbi-
ased and relatively precise total phosphorus load esti-
mates when the samples were selected randomly.
Strategies that confine sampling to the first half of the
year or neglect either the rising area or falling area of
the hydrograph will yield biased load estimates. A sys-
tematic sampling strategy will insure that each sample
within each strata has an equal probability of being se-
lected and usually yields unbiased total phosphorus
load estimates. Sample sizes necessary to estimate
total phosphorus loads were calculated for four of the
seven Michigan tributaries studied using load average
and variance predicted by flow variability versus load
variability regression equations. This method can be
used to provide sample size estimated for many tribu-
taries with little or no prior information about total
phosphorus concentrations but is not reliable for the
most event responsive rivers.

The report gives results of tests of indoor radon reduc-
tion techniques in 12 existing Maryland houses, with
the objective of determining when basement houses
with adjoining wings require active soil depressuriza-
tion (ASD) treatment of both wings, and when treat-
ment of the basement alone is sufficient In five base-
ment houses with adjoining slabs on grade, ASD treat-
ment of both wings provided an incremental additional
radon reduction of 0 to 5.2 pCi/L, compared to ASD
treatment of either one of the slabs alone. However,
basement-only treatment reduced radon to <4 pCi/L
in all five houses. In six basement houses haying ad-
joining crawl spaces, ASD treatment of both wings (in-
cluding sub-liner depressurization of the crawl space)
provided little additional reduction compared to base-
ment-only treatment, when sub-slab communication
was good. When communication was not good, treat-
ment of both wings was required to achieve <4 pCi/L
Tests of one fully slab-on-grade house showed that,
when there is good aggregate under the slab, a one-
pipe sub-slab depressurization system can achieve
<1-2 pCi/L, even when there are forced-air supply
ducts under the slab.

from facilities, including releases from past disposal
practices. The document also describes the collective
EPA/State principles guiding Northwest RCRA correc-
tive action program and major clean-up decisions such
as prioritization of the investigation and clean-up of the
RCRA facilities and the identification of dean-up
standards. The major principle guiding the program is
to address the 'worst case' first, based on a priority
ranking scheme described in the strategy. Topics con-

The Urban Bay Action Program (1) identifies priority
problem areas of contamination; (2) identifies current,
historical, and potential sources of contamination; (3)
establishes schedules to take corrective actions to
eliminate existing problems and to investigate poten-
tial problems; (4) identifies appropriate agencies for
implementing corrective actions; and (5) ensures the
implementation of the resulting plan. The first two of
these four objectives of the action program were met
and documented in an earlier report titled Sinclair and
Dyes Inlets Initial Data Summaries and Problem Identi-
fication. The third and fourth objectives were met and
are contained within the 1990 Action Plan. The fifth ob-
jective, plan implementation, will be documented in
future updates and revisions of the action plan. The
action plan represents the concerted efforts and com-
mitments of many regulatory agencies and local gov-
ernments to reduce contamination in Sinclair and Dyes
Inlets. Corrective actions may include both source
controls and remedial (cleanup) actions such as cap-
ping or removal of contaminated sediments. Source
controls may include permit revisions to require reduc-
tion of contaminant concentrations or volumes of dis-
charges, or application of control techniques to reduce
contamination of surface runoff. In addition, the follow-
ing levels and types of actions are also included: plan-
ning and program development actions, sampling and
longer term monitoring actions, resource enhance-
ment actions, and educational actions.

A field intercomparison of four wet-only precipitation
samplers were performed to assess their ability to effi-
ciently collect rain and selected organic contaminants.
Samplers are evaluated and compared on the basis of
their ability to efficiently collect rainfall, exhibit me-
chanical reliability, demonstrate adequate operational
characteristics and provide precise measures of wet-
only inputs. The most significant difference between
the four samplers was their mechanical reliability in the
field. The samplers performed equally well in assess-
ing organic concentrations in rain. The sampler inter-
comparison was conducted in part to select the pre-
ferred characteristics of a rain sampler that must be
deployed in the field unattended for up to two weeks.
The MIC sampler, properly maintained, is suitable for
such a purpose. Of the two modes of compound isola-
tion tested, the resin adsorbent (XAD-2) exhibited
modestly higher concentrations that the solvent MIC
but had the disadvantage of ease of sample handling
and lower blanks. Both could be operated with proper
maintance to provide precise data. The stainless steel
and Teflon coated funnel surfaces provided compara-
ble data.

Atmospheric scientists engaged in climate change re-
search require a basic understanding of how ecologi-
cal effects models incorporate climate. The report pro-
vides an overview of existing ecological models that
might be used to model climate change effects on
vegetation. Some agricultural models and statistical
methods are also discussed. The weather input data
requirements, weather simulation methods, and other
model characteristics relevant to climate change re-
search are described for a selected number of models.
The ecological models are classified as btome, eco-
system, or tree models; the ecosystem models are fur-
ther subdivided into species dynamics or process
models. In general, ecological modelers have had to
rely on readily available meteorological data such as

The research performed under this cooperative agree-
ment is summarized in the contents of four papers.
The first is on The Determinants of Value for a Marine
Estuarine Sportfishery: The Effects of Water Quality in
Texas Bays'. The objective is to formulate special sta-
tistical models that produce estimates of each individ-
ual's willingness to pay for access to the recreational
fishery in the eight major bays along the Texas Gulf
Coast. The second paper is on 'Combining Contingent
Valuation and Travel Cost Data for the Valuation of
Non-Market Goods.' The primary methodological inno-
vation in the paper is to combine both travel cost and
discrete choice contingent valuation data in one com-
prehensive model. The paper also breaks new ground
by freeing up certain parameter restrictions within the
jointly estimated model so that the travel cost and con-
tingent valuation data are allowed to imply different
preferences. Finally, the third and fourth reports are
applications. The first is called 'Using the Basic 'Auto-

The report lists those individual contractors in the
United States who have met the requirements of the
Radon Contractor Proficiency (RCP) Program as of
August 18, 1990. These requirements are designed to
provide minimum proficiency criteria for individuals
who design and supervise the installation of radon miti-
gation systems in buildings. (Some States have more
stringent requirements as part of their radon certifica-
tion programs. The States should be consulted directly
for details on their programs; see Section 5 for a list of
State radon contacts). The RCP Program measures
the proficiency of an individual contractor, not their
company. Therefore, users of the report who select a
mitigation firm should ensure that the services are pro-
vided by the listed contractor. The National RCP Pro-
gram does not accredit mitigation contractors, nor
does it certify, recommend, or endorse participating
companies. Only the listed contractor, not their com-
pany of affilation, are deemed proficient. The inclusion
of a contractor in the report should not be interpreted
as a certification or accreditation of the individual or af-
filiated company.

A computer model package 'ASPAIR' was developed
in the project to describe the air stripping process
along with processes for controlling the air emissions.
The package is integrated with a commercially avail-
able process simulator called ASPEN to design and
cost an air stripper and emission control system for
specific applications. The applicability of the ASPAIR
model package was demonstrated through several
case studies which highlighted the effect of important
parameters such as, Henry's Law constant, gas to
liquid ratio, VOC removal efficiency, and wastewater
throughput. The results of these case studies are pre-
sented in a graphical form to allow quick 'short-cut' es-
timates of the performance and cost of an air stripper
and associated air emissions control units. Two figures
are provided in the manual that illustrate the capital
and annualized costs as a function of wastewater flow
rate and Henry's Law constant for a desired VOC re-
moval efficiency of 90%. Two additional figures are
provided that illustrate a similar cost correlation for a
desired VOC removal rate efficiency of 99%. The
manual also provides capital and annualized costs
graphs for catalytic oxidation and carbon adsorption
units used to control the emissions from air strippers.

Two new methods for real-time measurement of gase-
ous formaldehyde have been developed.  One  is a
spectroscopic method based on direct fluorescence
detection of gaseous formaldehyde following excita-
tion with UV light This method has been developed to
the prototype stage by modifications of a commercial
fluorescence SO2 detector to convert it to formalde-
hyde detection. The prototype spectroscopic formal-
dehyde monitor exhibits a detection limit of < 30 ppbv,
with a time response of about one minute. The second
method is based  on  derivatization of formaldehyde in
aqueous solution to  form a fluorescent product  The
detection of fluorescent product was made more sen-
sitive  by using intense 254 nm light from a mercury
lamp for excitation, thereby allowing use of a simple
and efficient glass coil scrubber for collection of gase-
ous formaldehyde. The wet  chemical formaldehyde
monitor incorporating these improvements exhibits a
detection limit for gaseous formaldehyde of 0.2 ppbv
and for aqueous formaldehyde of 0.2 micromolar  with
time response of about one minute, following a lag
time of 2 minutes. Both instruments were tested in the
laboratory with gaseous formaldehyde standards, and
the aqueous scrubbing/analysis  method  was  field
tested by continuous operation over a 10-day period in
which outdoor and indoor air were sampled for alter-
nate half-hour periods. A  comparison of real-time
(aqueous scrubbing/analysis) and integrated meas-
urements, using  dinitrophenylhydrazine (ONPH) im-
pingers, showed  close agreement between the real-
time and ONPH data, even at concentrations as low as
1ppbv.

The report  covers basic  and applied  studies  con-
cerned  with three Limestone  Injection Multistage
Burner (LIMB) process objectives: (1) avoiding degra-
dation of collection efficiency in the electrostatic pre-
cipitator (ESP) during LIMB, (2) achieving satisfactory
sulfur  dioxide (SO2) removal, and (3)  disposing of
LIMB waste products. Tests were performed on South-
em Research Institute's (SRI's) pilot scale combustor
and on the full scale operating ESP at the Edgewater
plant SRI's testing coincided with the Edgewater LIMB
demonstration, and significant test results were incor-
porated  into the demonstration to enable the demon-
stration to meet its goals. The use of low-level spray
humidification was found adequate to  restore clear'
stack conditions  which  had  severely deteriorated
under LIMB without humidification. Water spray was
also required for the enhancement of SO2 capture.
Analytical data gathered on the waste product appears
to confirm the acceptability of disposal in a landfill.
There is also a report on the preliminary evaluation of
the Advanced Silicate process, concluding that the
process offers potential for greatly enhancing SO2 re-
moval in connection with LIMB but cautions that sub-

ered.

The Advanced Statistical Trajectory Regional Air Pollu-
tion (ASTRAP) model simulates long-term transport
and deposition of oxides of sulfur and nitrogen. It is a
potential screening tool for assessing long-term ef-
fects  on  regional  visibility  from  sulfur emission
sources. However, a rigorous evaluation  is required
before the model can be recommended for the particu-
lar application.  As a first step, the authors modified the
original 1985 IBM-3033 version of the model to create
the ASTRAP-EPA version for applications on the EPA
VAX-8600 computer using existing EPA preprocessed
meteorological and  emissions data files. Additional
modifications improved the model design by eliminat-
ing several model assumptions and replacing some
modeling approaches. The cumulative effect of the
model modifications was assessed by comparing the
quarterly 1980 calculations of sulfur wet deposition of
both versions with screened measurements. The sea-
sonal correlation coefficients and standard errors of
each model  version are insignificantly different at the
0.05 level, demonstrating that the two model versions
indeed  produce  similar results.  In general, the im-
provements  in model design only slightly enhance
model performance. Sensitivity of ASTRAP-EPA cal-
culations of  sulfur wet deposition was also assessed
for several model assumptions  and  values of model
parameters. ASTRAP-EPA model predictions are most
sensitive to three parameters - the model time step,
the truncation of trajectories near the border of wind-
data-void regions, and the temporal aggregation of en-
semble  trajectory statistics. The maximum quarterly
predictions of sulfur wet deposition, across southwest-
em Pennsylvania and  northern West Virginia, de-
crease by as much as 30% when either the model time
step changes from 3 hours to 6 hours, or when trajec-
tories are not truncated, or when trajectory statistics
are not temporally aggregated.

The report describes the initial evaluation of a particle
beam liquid chromatograph/mass spectrometer for
the analysis of polar semivolatile organic compounds
in air samples. The study was concentrated on exam-
ining and  optimizing instrumental operating param-
eters, evaluating the ability of the instrument to gener-
ate classical electron impact  mass spectra of repre-
sentative compounds, investigating the performance
with chemical  ionization, and evaluating the potential
for quantitative analysis with selected compounds.
Test compounds included hydroxy-polycyclic aromatic
hydrocarbons  (PAH), nitro-PAH, amino-PAH, and hy-
droxynitro-PAH. The report describes the results  of
these experiments  and  discusses several problems

The report is an initial evaluation of significant anthro-
pogenic sources of radiatively important trace gases.
Emissions of greenhouse gases from human activi-
ties-including fossil fuel combustion,  industrial/agri-
cultural activities, and transportation-contribute to the
increasing  concentrations  of radiatively  important
trace  gases (RITGs) in  Earth's atmosphere. Trace
gases of concern include CO2, N2O,  CH4, chlorofluor-
ocarbons, and  O3. NOx and nonmethane hydrocar-
bons, while not themselves radiatively active, can con-
tribute to  the buildup of RITGs. The U.S. EPA has con-
ducted several research projects characterizing emis-
sions from specific sources of RITGs, the purpose of
which was to rank sources of RITGs according to their
potential  impacts on radiative forcing and to develop
country- and source-specific emission factors where
data were adequate to warrant emission factor devel-
opment Country-specific emission factors were devel-
oped for coal-fired utility boilers, natural gas transmis-
sion/distribution systems, municipal  solid waste  land-
fills, rice cultivation,  and  transportation  sources.
Sources  for which country-specific emissions  data
were collected, but for which emission factor develop-
ment could not be supported at this time, include coal
mining   operations  and   miscellaneous/industrial
sources of methane.

The main objective of the third version of the manual is
to provide a set of standardized, technically sound and
well documented, methods that would allow data or
measurement precision and bias to be estimated and
controlled, and thus promote the comparability of for-
estry field data  across sites, research projects, and
time. Although the concepts of standard operating pro-
cedures  (SOPs), Quality  Assurance  activities, and
quality control procedures have been deeply ingrained
in many fields of research and manufacturing for dec-
ades, their utilization  and  acceptance in forestry  has
been  minimal. Uniform, or standard,  measurement
methods are critical to projects that contribute data to
some central data base for synthesis,  integration, or
assessment  efforts. Consistent methods are particu-
larly important to projects monitoring change to forest
systems over time. Standardized methods, with known
or estimable errors,  contribute greatly to the confi-
dence associated with decisions based on field data
collections. The  procedures are  meant to serve as
guidelines to the minimum activity necessary to pro-
vide high quality data for an integrated research pro-
gram. Finally, the methods manual should serve inves-
tigators by simply reducing the amount of documenta-
tion required for an assessment of the data quality if
they simply  note that the procedures used,  or pro-
posed to be  used, are those suggested in the manual.

The report gives results  of 12-month-long alpha-track
detector (ATD) measurements of indoor radon con-
centrations, between December 1988 and December
1989 in th living areas of 38 of 40  houses where radon
reduction techniques has been installed 2-4 years ear-
lier in a  previous  EPA  project.  The techniques, in-
stalled between June 1985 and June 1987, generally
involved active soil depressurization. In the 28 houses
in which the mitigation  system  operated the entire
year, the annual average was < 2 pCi/L in 13, and <
4  pCi/L in 22. The residual radon in many houses is
due largely to re-entrainment of  ASD exhaust. Com-
parison of these annual  ATD results with quarterly re-
sults from the past three winters shows that 22 of the
28 houses had annual measurements within 1 pCi/L of
the winter-quarter result. There had been no significant
degradation in system performance,  except where the
mitigation fans failed or where the owner had turned
off the system. Six of 34 ASD fans have failed to date.

A standard mussel homogenate was analyzed for total
lipid mass, lipid  class components, and PCBs using
four different extraction procedures in an  attempt to
determine the most appropriate method  for  use in
bioaccumulation studies of  lipophilic organic  pollut-
ants. The four procedures included: chloroform/meth-
anol/water  (similar to the  classical Bligh and Dyer
method),  hexane/acetonitrile/water,   and  hexane/
methanol/water extractions at controlled v/v/v ratios;
and a  hexane/acetonitrile method requiring minimal
solvent volume ratio control. TLC analysis of the lipids,
alone, was insufficient to determine qualitative distinc-
tions between the extraction procedures studied; how-
ever, latroscanfTM) technology was able to provide in-
formation on both  the qualitative and quantitative dis-
tribution of lipids in the various extracts.

 Supercritical fluid extraction has been publicized as an
 extraction method which has several advantages over
 conventional  methods, and it  is expected to result in
 substantial cost and labor savings. The study was de-
 signed to evaluate the feasibility of using supercritical
 fluid extraction as a sample extraction method for pol-
 lutants  and matrices of concern to the EPA. Various
 matrices were spiked with compounds from  several
 classes of pollutants and were extracted with supercri-
 tical carbon dioxide, with and without modifiers. Based
 on the  results, a  preliminary protocol was developed
 which was then tested with additional simple and com-
 plex matrices. Another important segment of the work
 was to  study  the influence of variables on recoveries.
 The results of the study indicate that supercritical fluid
 extraction with carbon dioxide, with or without modi-
 fiers, is an attractive method for the extraction of or-
 ganic contaminants from environmental solid matrices.
 Potential advantages of the method include less sol-
 vent use and disposal, reduced manpower require-
 ment, and  increased speed and selectivity. However,
 more developmental work has to be done before su-
 percritical fluid extraction becomes an easy-to-use,
 off-the-shelf method.

 A broad view must be taken when considering the pos-
 sible impacts and implications of municipal (urban) ac-
 tivities on a water body because of the high costs and
 permanence of the actions. This is especially true
 where an extensive land/water interface exists and
 the water body is an estuary that functions as an im-
 portant fishery and wildlife nursery area. When the es-
 tuary is an especially important part of a Great Lake, it
 is essential to consider the ecological complexity and

 that could ensue from improper usage and short-sight-
 ed decisions.

The paper describes newly developed software called
the  AIDE  Interaction   Development  Environment
(AIDE). AIDE provides a straightforward, consistent
methodology  for  designing and  implementing  new
interactive interface  systems for environmental soft-
ware. AIDE combines a toolkit of utility subroutines for
building individual interactive screens with instructions
for developing two parallel products: a file containing
all text questions, and messages used in interactive
communication, and a FORTRAN program containing
the control strategy  and sequencing instructions for
interactions. The system  provides an efficient means
for storing and updating  screen contents. The  AIDE
package is based on a re-evaluation of currently avail-
able tools and ideas for constructing a user interface.
Accordingly,  the   manual draws  on  an  expanding
 knowledge of the 'human factors' involved in effective
 design of man-machine interfaces.

 The United States Environmental Protection Agency is
 responsible for developing methods to control poten-
 tially harmful chemicals entering the environment. The
 determination  of harm is often  based  on  laboratory
 toxicity tests of chemicals using plants and animals.
 The vast number of toxicity tests of single chemicals
 that have been produced to date provide an extensive
 data base to help determine potential harm of chemi-
 cals to humans and the environment. At Corvallis, the
 authors  have  been working on various toxicity test
 methods  and  on  site characterization/assessment

 Simulation models  have been employed to examine
 the effects of global climate change on forest ecosys-
 tems in the southern United States. Predictions for the
 region suggest a warmer climate in the next  century.
 Shifts  in forest species  distribution and composition
 are projected in response to climate change within the
 next 50-80 years. A long-term decline in forest produc-
 tivity could occur and timber production, biotic habitat,
 water quality and quantity from watersheds, soil prop-
 erties,  and recreation opportunities could be altered.
 Forest management planning by industry, non-industri-
 al private landowners and public agencies will be influ-
 enced by climate change impacts. Forest regeneration
 practices, silvicultural treatments and rotation lengths
 in natural and managed forest may need to be adjust-
 ed to cope with climate change. An increase in risk as-
 sociated with climate change events will likely influ-
 ence investment decisions regarding intensive forest
 management by owners and managers.

Determining the appropriate ozone exposure index for
a secondary ambient air quality standard requires a
consideration of the underlying biological basis for the
response and  a method of describing the temporal
fluctuations in  pollutant concentrations. An exposure
index that adequately relates chronic pollutant expo-
sure and the reduction in agricultural crop yield using a
set of data for a specific year and site should give com-
parable proportional yield loss estimates for experi-
ments replicated in time and/or space under  similar
environmental  and edaphic conditions. This perspec-
tive is used to  evaluate the adequacy of several indi-
ces of O3 exposure for use in describing the exposure-
response relationships for the major agricultural crops
studies by the U.S. Environmental Protection Agency's
National Crop  Loss Assessment Network (NCLAN)
program and Pennsylvania State University (PSU). Al-
though results indicate that no single exposure index is
'best' for all species, several general trends are indi-
cated from studies replicated in time under similar en-
vironmental conditions but with varying exposure dura-
tions. Year-to-year differences in the magnitude of re-
sponse were minimized by exposure indices that are
cumulative and weight peak concentrations more than
low concentrations. Because these indices may have
potential for use in a standard setting process, the au-
thors recommend that efforts to validate the  results
from the NCLAN and  PSU studies focus on  under-
standing the biological basis for the response through
additional data sets and future field experiments on
crops.

The eleven western states occupy about 40% of the
land  area of the conterminous United States. The
West is characterized by extreme relief with massive
north-south  oriented mountain ranges separated by
basins, valleys, and  plateaus. This physiography is an
important determinant of the exposure and  response
of western forests to air pollution. Topographic modifi-
cation of regional climate determines which areas can
support forests. Patterns of relief influence the distribu-
tion  of pollutant sources relative to forests and the
transport of pollutants from source areas, so pollutant
loading to western forests is also influenced by topo-
graphic patterns. The chapter presents a broad over-
view of western physiography and forest types as a
framework for later chapters. Discussion of patterns
within forest types focuses on topographic and mois-
ture relationships.

 The accumulation of greenhouse gases in the atmos-
 phere over the past century is projected  to cause a
 warming of the Earth. Climate change predictions vary
 by region and terrestrial biosphere response and feed-
 backs will be ecosystem specific. Forests play a major
 role in the Earth's carbon cycle through assimilation of
 C02, storage of carbon, and emission of greenhouse
 gases. Simulation models have been employed to ex-
 amine the possible  responses to climate change of
 global forest ecosystems. Major shifts in forest species
 distribution and composition are predicted in response
 to projected climate change  within the  next 50-80

 A two-dimensional, convective-dispersive transport
 model was used to predict bounds on the expected
 long-term time-averaged dilutions for wastes disposed
 of at the  106-Mile Ocean Disposal Site (between 38
 deg 40 min and 39 deg 00 min N, and 72 deg 00 min
 and 72 deg 30 min W).  Potential concentrations  of
 wastes near the outer continental shelf were of par-
 ticular interest because of the presence of commercial
 and sportfishing grounds. The major model assump-
 tions were (1) the wastes were completely mixed verti-
 cally and remained in the upper mixed layer, (2) the ex-
 pected center of mass of a discrete dump of material
 was convected from the disposal site with the  mean
 horizontal current, (3) the expected dispersion of a dis-
 crete dump of material about its center of mass was
 determined by the variance and correlation structure
 of current velocities, and (4) the  expected long-term
 time-averaged plume can be estimated by superim-
 posing the expected distributions of the individual
 dumps.

There  is increased interest among federal and state
regulatory agencies and water utilities in the  factors
that result in water quality deterioration between the
treatment plant and the consumer* tap. This has result-
ed in  a  number of efforts  being  made to develop
models that predict the propagation of contaminants in
distribution systems. The U.S. EPA, in cooperation with
the  North Penn Water Authority has developed and
field tested such a model. The model has undergone
extensive field testing. In addition several continuous
samplers  have  been tested  and evaluated. The EPA
model was used in a recent waterborne disease out-
break study in Cabool, Missouri, in which the U.S. EPA
and CDC collaborated. The model was instrumental in
assisting the CDC to reach the conclusion that the out-
break  was in fact waterbome and  probably due to a
waterborne contaminant that was introduced, possibly
from sewer overflows that occurred at the  same time
as two line breaks in the distribution system.

 The distributions of nine trace metals in flue gas panic-
 ulate by particle size range were determined as part of
 a  pilot-scale hazardous waste  incineration test pro-
 gram. These tests were conducted in the rotary kiln in-
 cinerator system at the U.S. EPA's Incineration Re-
 search Facility in Jefferson, Arkansas. The metals (ar-
 senic, barium,  bismuth, cadmium, chromium, copper,
 lead, magnesium,  and  strontium) were fed to the kiln
 as part of a synthetic waste. Testing was designed to
 evaluate the effects of kiln temperature (varied from
 816C to 927C) and waste feed chlorine content (varied
 from 0% to 8%) on metal distributions. Flue gas panic-
 ulate samples, collected at the afterburner exit, were
 size-fractionated,  yielding  ranges of nominally  less
 than 2 micrometers, 2  to 4 micrometers, 4 to 10 mi-
 crometers, 10 to 30 micrometers, and greater than 30
 micrometers. Increasing kiln temperature from 816C to
 927C caused the  average distributions to shift from
 roughly 20% less than  10 micrometers to an average
 of 60% less than 10 micrometers for all metals except
 chromium. An increase in waste feed chlorine content
 from 0% to 4% caused the distributions of cadmium,
copper and lead to shift from roughly 20% less than 10
 micrometers to 55% less than 10 micrometers. No fur-
ther effects were observed for these three metals as
feed chlorine increased from 4% to 8%. For Chromi-
um, increasing chlorine content from 0% to 4% to 8%,
caused a corresponding shift of 2% to 20% to 50% in
the less than 10 micrometers fraction.

Presented at the Congressional Workshop on 'Quality
and Safety of Bottled Water', Washington, DC., Sep-
tember 13-14,1990.

Bottled water, in general, is an excellent source of
drinking water, but is subject to contamination if not
properly protected at the source, during bottling oper-
ations, transit to retail outlets and storage at home.
These facts dictate a need for a uniform national policy
to monitor bottled water by the FDA, State agencies or
local  government at a  frequency that relates to the
consumer base (interstate or intrastate) for each bot-
tled water producer. This frequency of bacteriological
sampling based on population served should be that
specified in the Federal Regulations  for public water
supplies. Since unsatisfactory bottled water lots would
be subject to recall, each container should be marked
with a lot number or preferably a bottling date to assist
in the identification of contaminated supplies.  Produc-
tion dates would also  provide the  consumer  with
knowledge on freshness of supply and possibly assist
in the movement of fresh  supplies  from the retail
shelves. While there will generally be  some change in
bacterial quality during storage before sale, refrigerat-
ed storage will slow the process and hold the hetero-
trophic bacteria  densities to below 1,000  organisms
permL

Changes in waste  disposal patterns prompted by
newly enacted legislation has resulted in a significant
change in the composition of hazardous wastes pre-
sented for incineration.  Metal-containing wastes that
were historically landfilled are now being incinerated
with  increasing frequency. To study  the distribution
patterns of metals that are subjected to incineration, a
series of pilot-scale incineration tests  were performed
at EPA's Incineration Research Facility.  Utilizing the
variables of: combustion temperature and  feed chlo-
rine concentration, a series of eight tests were com-
pleted to evaluate the behavior of: arsenic, barium, bis-
muth, cadmium, chromium, copper, lead, magnesium
and strontium.

The specification of natural NOx emissions may be im-
portant for regional-scale air pollution modeling. Now
that a national lightning detection network is operating,
it is possible to  make episodic estimates of lightning
generated NOx emissions and to resolve these emis-
sions to fine spatial and temporal scales. The paper re-
ports on an approach that was used to estimate NOx
emissions for the Regional Oxidant Model in the north-
eastern United States.

EPA's Regional Oxidant Model (ROM), a three-dimen-
sional model capable of describing photochemical
smog  on scales of 1000 km, is being used to analyze
large scale pollution patterns and the effectiveness of
particular emissions control  strategies on  reducing
ozone concentrations. The ROM demands consider-
able computation time to perform its calculations, par-
ticularly the chemical calculations. The model currently
simulates at much less than one-half of 'real-time' on a
VAX 11 /780 (one day of model time requires over two
days of  simulation time). A feasibility study was per-
formed to support the design of a computing solution
to accelerate the simulation. The study suggested the
construction of a prototype  parallel multiprocessor
system using off-the-shelf computers, interconnected
by Ethernet, as a low-risk method of increasing soft-
ware performance up  to  10-20x over uniprocessor
speed. The prototype consists of 22 rtVAX 1000 com-
puters as processing elements (PEs), and a VAXsta-
tion II/GPX host computer. Current work is focused on
developing a variation of the tiled ROMMP (Regional
Oxidant  Model Multi-Processor), in  order to distribute
the entire computational problem to the PEs. This ap-
proach is expected to avoid the host-computational
bottleneck, and achieve high levels  of utilization on all
the PEs in the prototype.

cities and their environs include ozone, sulfur dioxide,
carbon monoxide, lead, and particulates or aerosols
(including the politically important acid aerosol precur-
sors of acid rain). Although studies generally consider
the outdoor environment in the context of air pollution,
there is also a considerable body of evidence describ-

 Sediment toxicity  tests  have been developed on the
 basis of virtually all levels of  biological organization
 from sub-cellular  through model ecosystems. Rapid,
 cost-effective techniques  based on acute exposures
 are often used in research and regulatory programs to
 determine the spatial and temporal distribution of sedi-
 ment toxicity, and the relative  toxicity of individual
 chemicals and complex wastes spiked into sediment.
 Sediment toxicity tests are part of several comprehen-
 sive methods for generating sediment quality cnteria.
 Major research needs include test methods for chronic
 exposures, field validation of acute toxicity tests and
 the geochemical integrity of test materials, the relation
 between toxicity and the bioavailability/partitioning of
contaminants in different sediment phases, models of
toxicological interactions between sediment contami-
nants, and sediment wasteload allocation models.

volume. In a similar vein the papers are discussed in
relation to an outline of a risk  assessment framework
which may be useful in guiding both regulatory action
and future research. It is concluded that marine envi-
ronmental process research has a role to play, but not
an exclusive role in regulation. The nature of the envi-
ronment  is such that  not  all  the scientific questions
have been answered, nor can they be expected to be
answered in the near future to the satisfaction of regu-
latory agencies or the  public  at large.  Consequently,
regulatory actions must incorporate other approaches
and research must be supported that focuses on criti-
cal environmental problems.

 Three computer  programs, PLUME,  OUTPLM, and
 DKHPLM,  have been used by the U.S. Environmental
 Protection Agency and municipalities to estimate initial
 dilutions of sewage  discharged  into marine environ-
 ments. Modification  of the input parameters  for the
 three  programs,  while maintaining  the  appropnate
 gravitational direction  and ambient density gradient,
 permitted the use of the programs to predict the cen-
 terline dilution, trapdepth, and maximum penetration of
 neqatively buoyant fluids. Drilling fluids and other neg-
 atively buoyant fluids were discharged downward into
 a 4000-liter tank of stratified, static seawater to obtain
 verification data.  Time-lapse photographs were taken
 through a window,  and replicate synoptic samples
 were obtained through 3-7 sampling ports along the
 centerline of the fully developed plumes. Samples
 were analyzed gravimetrically for total solids and spec-
 trophotometrically for  soluble  components. The con-
 clusions were (1) all three computer program predic-
 tions were in good agreement with the measurements
 and observations made on a limited number of repre-
 sentative plumes generated in  the hydraulic modeh
 and (2) the solid and soluble components of the tested
 drilling fluids appeared  to dilute  at dissimilar  rates
 within the buoyancy and momentum-dominated initial
 dilution phase.

Human exposure  to complex  mixtures of genotoxic
indoor air pollutants can be assessed using several dif-
ferent  bioanalytical methods. External exposure can
be  assessed using micromutagenesis methods to
measure human exposure to mutagens. Internal expo-
sure and dose can be assessed using macromolecular
adducts (e.g., DNA adducts).  Urinary  metabolites of
specific components and  the mutagenicity of urine
have also been used as bioindicators of exposure. Ex-
ternal exposure to the mutagenic activity of tobacco
smoke is readily measured indoors and results in the
highest reported exposure to mutagens. External ex-
posure to mutagens from ETS has been compared to
internal exposure  by using urinary  measurements of
the nicotine metabolite, cotinine. The  organic matter
(tar) from particles emitted from tobacco smoke and
other combustion  sources is genotoxic to cells, carci-
nogenic to animals, and  results in the formation of
DNA adducts.

 The standard mutagenicity bioassays that are readily
 applied to the evaluation of outdoor air samples col-
 lected by high volume samplers are not sufficiently
 sensitive to measure the mutagenicity of low volume
 air samples collected indoors. Two microsuspension
 mutation assays using various strains of Salmonella ty-
 phimurium were evaluated for the assessment of
 indoor air pollution. One assay used highly sensitive
 YG strains of bacteria in a histidine reversion assay.
 The other was a forward mutation assay detecting 8-
 azaguanine resistant mutants in the TM677 strain. To
 decrease the required sample mass in the forward mu-
 tation assay, the volume in the preincubation step was
 decreased 10-fold to produce an ultra microsuspen-
 sion  assay. By applying these assays to indoor air
 samples, their usefulness was confirmed in investigat-
 ing the effect of smoking, ventilation or air condition-
 ing.

 The architectural  arrangement of the small airways
 and distal gas exchange region in the lungs is obvious-
 ly critical in determining  the  sites  of deposition of
 gases and particles as well as in subsequent tissue re-
 sponses due to injury. In the chapter, the results of
 quantitative determination of the structure of the small
 airways and gas exchange regions of the lungs will be
 covered. Because extrapolation of experimental stud-
 ies in laboratory animals to the adverse health effect in
 man is a central interest, the authors are particularly in-
 terested in comparing the structure of  the gas ex-
 change region of different species and the implications
 that these differences in structure have on dosimetry.
 The complex architecture of  the pulmonary airway
 system  has made the calculation of dose of inhaled
 pollutants delivered to specific sites in different spe-
 cies a difficult process. This difficulty is particularly ap-
 parent in the lack of structural data describing the gas
 exchange regions of the lungs where low level, chronic
 exposures to reactive gases and aerosols have their
 most significant effects.

 Data obtained from animal exposures may, if appropri-
 ately extrapolated,  be used to assess quantitatively
 the health risks of humans chronically exposed to envi-
 ronmental  airborne pollutants. The ability to make cor-
 rect extrapolations is critical in making full use of the
 results  of acute and chronic exposures in  laboratory
 animals. Extrapolation of experimental results be-
 tween different animal species requires several types
 of data, one of which is detailed data on the geometry
 of the lungs for each species, to determine the quantity
 of pollutant that reacts (or is deposited) in the various
 anatomic regions (trachea, bronchi, bronchioles, termi-
 nal bronchioles,  proximal alveolar and distal alveolar
 regions). Data on the geometry of the lungs are almost
 exclusively concerned with the geometry of the major
 airways. The concentration of previous work on the
 major airways reflects the fact that they are the major
 determinants of airway resistance.

Determining  the dose delivered to specific sites in the
lungs is a critical first step in modeling the potential
toxic  effects of airborne pollutants. An important
recent development in estimating site specific dosime-
try  has been combining  sophisticated  analytical
models to determine the delivery of inhaled pollutants
to the kings with relatively simplistic anatomic models.
These methods are particularly important in extrapolat-
ing experimental results in laboratory animals to pre-
dict effects in humans. The goal in such modeling ef-
 forts is to characterize the average response of the
 lungs. However, in evaluating lung pathology following
 low level, chronic exposures to reactive gases, one
 quickly becomes aware that the lesions are far from
 uniform. The presence of such patchy lesions resulting
 from chronic exposures of laboratory animals or life-
 time exposures of humans to various environmental
 pollutants is a frequent finding. The observation of a
 diseased area of the lung immediately adjacent to a
 normal healthy region is so common that it almost sti-
 fles the question of why it occurs. (Copyright (c) 1989

 Various treatment technologies have proven effective
 in controlling halogenated disinfection by-products
 such as precursor removal and the use of alternative
 disinfectants. One of the most promising methods for
 halogenated by-product control includes removal  of
 precursors before disinfection.  Research studies  in
 central Florida indicate that membranes are effective
 in removing halogenated by-product precursors from
 certain waters. Can membranes be used as effectively
 in other locations for most drinking waters so that they
 can be considered  BAT for disinfection by-products.
 There are also other regulatory concerns where mem-
 branes can provide adequate treatment. Membranes
 can be  used for removing inorganics  and radionu-
 clktes. Also,  with appropriate pilot-scale data, mem-
 branes could possibly be considered BAT for meeting
 the Surface Water Treatment Rule requirements.

Filtration of ground-water samples for metals analysis
is  an issue identified by the Regional Superfund
Ground Water Forum as a concern of Superfund deci-
sion-makers. RSKERL-Ada and EMSL-Las Vegas con-
vened a technical committee of experts in the areas of
ground-water geochemistry, inorganic chemistry,  col-
 loidal transport and ground-water sampling technology
 to examine the issue and provide technical guidance
 based on current scientific information. The  findings
 and recommendations of the committee were  that use
 of a 0.45 micron filter was not useful, appropriate or re-
 producible in providing information on metals mobility
 in ground-water systems, nor was it appropriate for de-
 termination of truly 'dissolved' constituents in ground
 water. A dual sampling approach was recommended,
 with collection  of both filtered and unfiltered samples.
 This means that added emphasis  is placed on appro-
 priate  well  construction  methods,  materials  and
 ground-water sampling procedures.

 The paper discusses the calcination and sintering of
 sorbents during  boiler injection  for dry sulfur dioxide
 (SO2) control, with emphasis on calcium hydroxide-
 Ca(OH)2-because of its superior reactivity with SO2
 and its  wide commercial availability. Calcination and
 sintering  are  of particular interest because  they
 produce the surface area, pore volume, and pore size
 distribution which are responsible for reactivity of the
 sorbent with SO2. Particle  size is also a significant
 factor. Considerable EPA  work has been  directed
 toward increasing the calcium utilization  of Ca(OH)2
 during furnace injection. Hydroxides have been pro-
 duced using a variety of surfactants in the water of hy-
 dratipn in an attempt to reduce particle size by pre-
 venting  agglomeration. Calcium lignosulfonate was
 shown to be the most cost effective material for reduc-
 ing particle size in laboratory-scale hydrations.

For more than the past two decades, the USEPA has
been aggressive in its research, development, per-
formance testing, and in encouragement of the regu-
lated use of proven thermal destruction  (or inciner-
ation) technologies for the environmentally acceptable
treatment and disposal of combustible waste streams.
Nationally, significant percentages of residential solid
waste, municipal sewage sludge, and a variety of in-
dustrial, chemical, and agricultural wastes are routinely
treated by thermal systems. The paper is an overview
of the state-of-the-art of land-based incineration, em-
phasizing both conventional and innovative hazardous
waste thermal treatment technologies  and regulatory
performance standards. High temperature systems,
low-temperature  thermal  desorption, pyrplysis units,
heat recovery, and newer systems involving fluidized
beds, oxygen-enriched combustion, plasma-arc units,
and solar-assisted incineration, etc. are discussed.

Both abiotic and biotic transformations of pesticides
occur simultaneously in the environment. Although the
dominance of abiotic transformations was demonstrat-
ed in some cases,  it often was assumed that biotic
transformations control the degradation of pesticides
in natural systems. It is difficult to offer a general esti-
mate of the relative importance of abiotic transforma-
tions under conditions that  enable both biotic and abi-
otic conditions to occur. Considerable research effort
is devoted to the development of predictive models for
the fate  of pesticides in the environment. Such
models, if successful, will help make the application of
pesticides  more efficient  and less environmentally
hazardous. (Copyright (c) 1990 Soil Science Society of

 The paper is an overview of the current understanding
 of methane (CH4) emissions from landfills that contrib-
 ute to global  climate change. The factors affecting
 landfill emissions are described and the uncertainties
 are identified. There appears to be a consensus in the
 international community that there are large uncertain-
 ties in the current estimates  of CH4 emissions. The
 work that is planned by the U.S. EPA  to improve the
 understanding of global emissions from landfills is de-
 scribed in the paper. The work is planned in coordina-
 tion with efforts in the U.S., the United Kingdom, Ger-
 many India, and other countries who are interested in
 working to improve the understanding of the emissions
 from landfills and how these emissions can be pre-
 vented  or mitigated.  CH4 is responsible for almost
 20%  of current increases in commitment  to global
 warming. Major anthropogenic sources of CH4 include
 landfills, coal mining, and  the production and distribu-
 tion of natural gas.

sites represents one  option for the disposal of such
wastes. Current U.S.  regulatory  and permitting prac-
tices with respect to ocean disposal are concentration

SubJecUve-Probabiltty-Based  Scenarios  for Un-
certain  Input Parameters: Stratospheric Ozone
Depletion.
RAND Corp., Santa Monica. CA.
J. K. Hammitt. Apr 90,14p N-3140-EPA/JMO/RC
Repr. From Risk Analysis, V. 10, No. 1, p 93-102.

Risk analysis often depends on complex, computer-
based models to describe links between policies (e.g.,
required  emission-control  equipment)  and conse-
quences (e.g., probabilities of adverse health effects).
Appropriate specification of many model aspects is un-
certain, including details of the model structure; trans-
port, reaction-rate, and other parameters; and applica-
tion-specific inputs such as pollutant-release  rates.
Because  these uncertainties preclude calculation of
the precise consequences of a policy, it is important to
characterize the plausible range of effects. In principle,
a probability distribution function for the effects can be
constructed using Monte Carlo analysis, but the com-
binatorics of multiple uncertainties and the often high
cost of model runs quickly  exhaust available re-
sources. A method to choose sets of input conditions
(scenarios) that efficiently represent knowledge about
the joint probability distribution of inputs is presented
and applied. A simple score function approximately re-
lating inputs to  a policy-relevant output, in this case,
globally averaged stratospheric ozone depletion, is de-
veloped. The probability density function for the score-
function value is analytically derived from a subjective
joint probability density for the inputs. Scenarios are
defined by selected quantiles of the score function.
Using this method, scenarios can be systematically se-
lected in terms of the approximate probability distribu-
tion function for the output of concern, and probability
intervals for the joint effect of the inputs can be readily
constructed.

lution, 'Ozone depletion, Probability density functions,
