Very large number  c/f tests (over 7000) were accumulated for each compound
in two or more replicate experiments.   Concurrent negative controls were
done with each, and positive controls were run occasionally.   Thirty
pesticides and seven other aiscellaneous compounds were tested and four

     Of the IS pesticides  (listed first in the table) which could be
tested at adequate concentrations, 4 (Captan,  Folpet, Bromacil and
Simuine) were found to be weak mutagens.  One (Cavodylic Acid) was
questionable but called negative.  The rest of the pesticides wer* so
toxic that only very low concentrations (0.1 - 5 ppm) cou'd be used
(usually for a reduced exposure time), and those are not considered
adequately tested, in view of results obtained with reference mutagens
at these concentrations.
     Two of the Biscellaneous compounds ("Tris" and PtCI^} were found to
be potent mutagens.  The rest were negative.

                              INTRODUCTION



     The mutagenicity tests carried out in this laboratory using Drosophila
                              V

were part of a larger program involving several test systems in several



laboratories.  It was not known how Drosophila systems would compare



with others in terms of sensitivity to detect mutagenicity.   Neither was


it known which genetic endpoints (in Orosophila) would be most adequate



in a screening test.  It was recognized that pesticides (especially the


insecticides) would pose special problems for genetic tests with fruit


flies.  The Drosophila screening system itself was therefore undergoing



definition and simplification during the course of these stuaies.


     The original plan was to test each compound in a step-wise manner



as follows:


     1.   Dominant lethal test (the fastest).  Stop if positive.


     2.   Chromosomal alteration test (a one generation test).



          Stop if positive.



     3.   Sex-linked recessive lethal test.



     It became clear, however, that the first 2 tests were not highly



sensitive (thus the lethal test had to be done in all cases) and were



not easy to do.  At the same time, evidence was mounting (esp. Vogel &


Scbels, 1976) that the sex-linked recessive lethal test is by far the



most sensitive Drosophila test.  It also, of course, includes chromosomal



alterations as well as "point" mutations.  It was decided, therefore, to



run only the sex-linked recessive lethal test.  The other genetic schemes


were dropped from the progrcm after the first few months and will not be



dealt with in detail in this report.
                                - 3 -

-------
     Many people have been hesitant to accept results with an insect as
relevant to man.   It was thought that insect metabolism was probably too
different.   These objectives have been considerably reduced by the
discovery (Vogel  and Sobels, 1976) that Orosophila has enzymes which
carry out metabolic activation similar to that effected by mammalian
enzyne ext-acts.
     The toxicity of many of the compounds did cause serious problems
and resulted in a "no test" conc'usion for some of the compounds.   For
those which could be adequately tested, the Orosophila results compared
quite favorably with the other systems, picking up 4 weak mutagens and 1
questionable one.  All of these except  1 were picked by at least 1
other system.  Two were found positive in all systems.

                            EXPOSURE METHODS
     Initial trials were aade of several other exposure methods (aerosol
spray, contact, injection) but the method chosen as most appropriate was
feeding.  Since flies walk on their food, contact is always involved
and, when vaporization occurs, the test substance is also i.thaled.  The
method thus seemed more complete and exposure more certain, and it
better mimicked human exposure routes.
     It was shown several years ago by Lewis and Backer (1968) that
feeding of autagens in glucose solution is effective.  They fed flies in
vials with a bit of soaked tissue (such as Chea-Wipes).  We chose to
feed in small disposable petri plates, with a disc of glass fiber filter
in the bottom.  This permitted easy observation and counting of dead
flies for toxicity information.

     At first, files were exposed ,toxicity p*m1ttfrKj) for 48 hours.
Later the tiae was extended to 72 hours,  to atke ingestfon Bore certain.
Flies cannot survive for aore than 24-36  fxmrt without drinking, but in
72 hours they should be obliged to inges.. ccr*.   Contact (and inhalation)
were also thus extended.
     Compounds were dissolved, when possible,  fn IX glucose.   During the
first year. OMSO was used for coapounds net **t«r soluble.   At tnat
ti*e, a decision was taken (after warnings vefced at the Fredericicsburg
siettinp) to avoid OMSO if possible.   Thus »*«y compounds were used in
suspension rather than in solution.
     The concentrations were chosen by tbe following criteria.  If toxic
at 2000 pp« or b«low, a concentration giving 41 near as possible to SOX
Mortality at 72 hours was chosen.  For very to»lc compounds,  the duration
of exposure was reduced as well as the concentration.   For non-toxic
coapounds, 2000 ppa was chosen as a reasonable upper Halt.

                    SEX-LINKED RECESSIVE LETHAL TEST Introduction
     This type of mutation is frequent (involving some 800 genes on the
X chromosome) and varied in nature (including both "point" fcutations and
chromosomal alterations).   Ihe test has beer, found in comparative studies
(Voget and Solels. 1976) to be aore sensitive in detecting chemical
mutagens thatn other tests in Drosophila.   We now feel that the sex-linked
recessive lethal test a*'>.*• should be an adequate probe for mutagenesis.

Stocks and Genetic Scheme
     Canton-S wild type Bales were exposed.  "CS" stock was used because
it has had a low spontaneous frequency over many years of use.  The
frequency averages about 0.15% with variations rarely exceeding 0.IX and
0.3Z.
     Treated sales were coated to "FMS" females.  The X-chrooosome of
this is marked with yellow, white and Bar and carries a complex of stock
inversions.
     Heterozygous F. females were mated individually to FM6 males (brothers
or stock males) and the F. of each was observed for the presence or
absence of "*" males.  Any culture having no or less than 5X of the
expected number of males was considered a lethal case and was. confirmed
by repeating the test with four individual heterozygous F. females mated
to FH6 males.
     Each treated or control male was transferred to new sets of FM6
females at intervals of 4, 3, 3 and 4 days, to produce 4 broods of
                                - 6 -

 progeny.   The  different broods swnple genn cells  in gradually  earlier
 stages-of development  at the time of exposure.  Mature sperm are  sampled
 in brood 1,  spennatids in brood 2,  spermatocytes  in brood  3 and spenoatogonia
 in brood 4.  These  are n«t "clean"  but  rather  "rough" samples, due  to
 the length of  the mating times- and  the  fact  that  chemicals may remain  in
 the body beyond the external exposure time.
»*
 "Cluster" detection and handling
      Treated and control mates were numbered,  mated and  transferred
 individually and the F, daughters of each were mated as  a  "family."
 This is done in order  to  detect cases  where more than 1 lethal ic
 produced by 1  male.  These cases will be referred to as  "multiples" (as
 opposed to "singles" and "nulls").  A multiple can be due  to multiple
 individual mutations (HIM) or to a  single mutation event in a  gonial
 cell, which then reduplicates and produces 2 or more sperm cells  carrying
 the same leti^l (a  "cluster").  The distinction (if possible)  between
 these  two circumstances is very important when attempting to  detect
 low-level mutagenicity.  With potent, mutagens  the contribution cf clusters
 Is insignificant and mass mating; of treated and  control males are  the
 rule.  When exposure is  simple (as  with radiation), and  oany  flies  can
 be exposed, the procedure  is often  to test only 1 daughter of  each
 treated or control  fly,  this avoiding both MIMs and clusters.  Exposure
 is not simple  with  chemicals and thus otner  precautions  must  be taken.
      Although  there are  pitfalls which  we recognize, *e  have  applied the
 following procedure to this data.   Whenever  a  multiple was found, a

-------
statistical sethod (devised by Seymour Abrahamson) was applied,  which
yields the probability (binomial  expedition) of that nuiber of  mutations
arising independently in a single sale given (a) the number of sales  in
that particular treated or control group which produced progency,  (b)
the average number of F. ffaa'les  tested per P. male and (c) thr  nutation
frequency.
     If the number of lethals in th* multiple greatly exceeded probability
we considered it a cluster and did not count these lethals.
     In addition, however, it was often necessary to Bake some subject.ve
judgments on particular compounds.  Vfrch the lethals in the replicate
treated groups tended to occur in multiples while those in the concurrent
control group did not, this might indicate "spotty" exposure.
     The summarized data are presented with presumed clusters removed,
but the corrections are indicated at the foot of the table.

Number of chromosomes tested
     The number of tests needed per compound or "compound equivalent,"
which would be any variant on a compound, such as dose level germ cell
stage or exposure method) depends mostly upon (a) mutagenicity - the
more mutable, the fewer tests needed to prove it, and (b) the increment
in frequency desired to detect.
     We have found that when the control rate is 0.1SX, and when it is
desired to detect (and prove statistically) an equal induced frequency
(a doubling of background), then about 8000 treated and 8000 control
chromosomes should be tested.  Our aim was therefore numbers of  this
magnitude, accumulated  in 2 or 3 replicate experiments.

Results and conclusions
     The data froa the recessive lethal  tests  is shown in tables 3
througn 52.  These are sundries per compound  per variation (i.e..
exposure concentration or variation in expsoure sethod).   Each is shown
with its concurrent controls,'which were usually shared with other
experiaents in the saoe "«-ims."   Table 3 may be consulted for the cumulative
control value (0.157X) and the control frequenc> variations over time
and from run to run.   The suaaary table at the beginning of this report
(table 1) shows the concentrations tested and  the conclusions as to
BHjtagenicity.
     The  pesticide results fall into three categories:
     (a)  Those whi~h were tested at concentrations above 10 ppm for at
least 24 hours and which yielded results indicating a weak autagenic
effect.  These were Captan, Folpet, Broaacil and Simazine plus possible
Cacodylic Acid.
     (b)  Those which were presumably tested adequately (as above) but
which yielded negative results.   These were Qicaofaa through Carbofuran
In table 1.
     (c)  Those which may not have been adequately tested, since tney
were highly toxic, were used at  very low concentrations and gave negative
results.
     For the four compounds cal'ed positive, the conclusion was based
upon the experiaents with 2000 ppa.  Captan, Sinazine and 6ro«acil were
tested simultaneously in run no. 37.  Folpet was tested -in run no. 38.
Both runs had controls with quite low frequencies, but this appeared to
                                - 9 -••

-------
be a true low period  for  the  stock.   See  table  3.  Run 37 was done with
a newly prepared stock  and  the control  was  the  first cf a series  giving
low values.   In all four  cases,  there were  several Multiples in the
treated series, but none  in the  controls.   (See page 7 for explanation
of multiples. )  These Multiples-were:
     CapUn - S Mies with  2, 2  Mies vtth  3. 1 M!C with 6
     Polpet - 4 Mles.*tth  2, 1  male with 3
     BroMctl - 3 Mies with  2.  I  aale  with 3.  1 wle with 4, 1 Hie
with 5
     StMzine - 4 Mies with  2,  2  Mies with 3
     When the Kastenbaua  and  BowMn statistical test (Mut. Res. 9 (1970)
527-549) is applied to the  data  for these compounds (using the SUM of
controls 37 and 38 to provide approximately equivalent nuabers of treated
a>td control tests), the result  is  as follows.
     Captan  is significant  at the  .01 level if  the Multiple of 6 is
 included.  Without the Multiple, it it  significant at the .05 level.
     BroMCil  is significant at the .01 level  if the Multiples (one of 4
 and one of 5)  are Included.  It barely  Misses significance at .OS without
 the*.
     SiMZine  had no Multiples  greater  than 3 and is significant at the
 .01  level.
     Folpet  also had no ocrrection factor but is significant only t the
                         2
 .OS  level.   Using the Chi' test, which  is soaewhat  less conservative
 than the Kastenbau«-Bow»an test, P = <  .02.  More iaportantly, the
 Folpet data  shows a peak of nwtagenicity in broods  2 and  3.  Using these
 broods only,  the result  is highly significant (Chi2 = 15, P = < .01).

-------
     In all these cases,  the deduction of multiples of 4, 5V  and 6 is
questionable, since there are also several multiples of 2 and 3, while
the controls have almost  none.
     It is possible that  exposure may have been "spotty" - i.e., some
•ales may have ingested or contacted or inhaled BOre than others, in
which case the compounds  may be nore mutagenic than the averaged results
indicate.
     Cacodylic Acid caused marked sterility of treated males, especially
in brood 3,  indicating a  cytotoxic effect on peri-meiotic cells.  Unfortunatel)
it is not possible to know from these experiments whether or not the
damage is genetic.  The recessive lethal frequency obtained in the one
adequate experiment (run  52) was actually 3 times the concurrent control
value.  The  latter, however, was exceptionally low, and in this case it
was not part of a consistently low control period.  (Controls were in
fact somewhat erratic during that time.)  There were no multiples in
control 52 and oily 1 multiple of 3 in the treateri males.  We thus
called the result negative but questionable.
     Data from the tests of miscellaneous compounds is shown in tables
37 through 43.  Tris and PtCl. were clearly mutagenic, with peak effects
in brood 2,  indicating an effect primarily on spernatids.  All others
w«r« clearly negative.
     The reference mutagens EMS, El and IMP wera positive when tested at
adequate concentrations.   EMS, a very potent mutagen, surprisingly gave
frequencies  very near control level when tested at very low concentrations
(2 and 4 ppm).  THP was negative at 100 ppm and 300 ppm.  QBE was tested
                               - 11 -

-------
only at low concentrations Arid was negative or questionable.  It is
probably that air exposur* technique was inappropriate for this valatile
compound.  In all these cav*t, however, there were multiples, indicating
possible spotty exposure.  0«ta for the reference autagens is in tables
44 through 52.                                          •

            OtfOMOSG»€ LOSS,  REARRANGKEWT AHO NON-DISJUNCTION
     The selfed consists of treating wles whose Y-chroaosom* has  pieces
of X-chromosom* on both arms, one marVert with Y* (the normal  allele of
yellow body) and the other with BS (Stone's Bar).  The Fj fifes are
observed for loss of either or both markers.   The test is relatively
fast, requiring only one generation, and appears to be simple.   In use,
however, we found that very large nuabers are required and interpretation
of results was difficult, due to the several different types  of variants
and their quite different meanings in terss of cytogenetic events.
Since the recessive lethal  test also picks up chromosomal rearrangements,
It was decided that this separate test was not worth the time and effo't
required.
     The data that was collected is shown in table 2.  The pesticides
gave frequencies varing from.5.31 to 20.29 x 10  , all with confidence
limits overlapping the control frequency.  Controls varied from 1.5 to
14.99 x "4.  Of the three reference eutagens Usteo, EMS and El gave
clearly positive results, but TOP did not.  Evidently it Is not an
efficient chromosome breaker.
     A new scheme, devised by Lor Ing Craymer (1974), cam* to our attention
and was tried in a preliminary manner as a possible replacement for the
Y*'Y'BS test.  This Is a selectlx* scheme. In  which the only survlvirs
are flies resulting from non-disjunction or certain chromosome breakage
events.  Since no actual tests were performed for this EPA contract, we
will not dwell on the test here, but only point out that it is a likely
candidate for future screening prograas.

     Methodology was -lev*loped for dominant lethal screening and tests
were performed (unfortunately using very low concentrations) on Siaazine
and Oicacba.  Siaazfne gave possibly positive results.  This test,
however, was also abandoned, since it was tiae-consuaing and would
probably rarely help avoid further testing.
