TOXICOLOGICAL INFORMATION

Animal Data
Cinch ATZ Lite
Oral LD50: 4824 mg/kg in rats
Dermal LD50: > 2000 mg/kg in rabbits
Inhalation 4 hour LC50: > 2.9 mg/L in rats
Cinch ATZ Lite is slight skin irritant, a slight eye irritant, and
a skin sensitizer in animal tests.
ATRAZINE
Effects in animals from single inhalation exposure to an 80%
wettable powder produced no observed signs of toxicity.
Toxicity described in animals from the administration of single
oral doses include central nervous system effects, hypoactivity
and frequent urination. In a 90-day feeding study in rats,
repeated oral dosing of 0.6 to 34 mg/kg bw/day resulted in
decreased body, liver and kidney weight in high dose males. Iron
pigments were found in the spleen of male and female rats at the
high dose level. Long term (2-year) dietary studies in rats
resulted in decreased body weight, decrease in red cell parameters
(female rats only), and changes in clinical chemical parameters at
0.6 mg/kg bw/day and above. Cardiotoxicity was observed in a
long-term study with high doses in dogs.
Atrazine is a weak carcinogen in one female rat strain producing
an increased incidence of mammary tumors in a two year feeding
study at 3.5 mg/kg bw/day and above. There were no tumors at 1.5
mg/kg/day and below. Atrazine was negative for carcinogenicity in
mice and was also negative in a different rat strain. Based on
this unique tumor response in a single rat strain and a review of
multiple studies, EPA and IARC have concluded that atrazine is not
likely to be carcinogenic to humans. Tests in rats and rabbits
indicate that Atrazine may have developmental toxicity but only at
maternally toxic dose levels of 70 mg/kg/day and above. It is not
a unique hazard to the conceptus. Tests in animals demonstrate
no reproductive toxicity.
The weight of evidence from bacterial and mammalian cell cultures
and from animal tests indicate atrazine does not cause genetic
damage.
ETHYLENE GLYCOL
Repeated ingestion exposure to Ethylene Glycol caused
histopathological changes of the kidneys and bone marrow; kidney
effects with oxalate crystal deposition; altered hematology, and
decreased body weight. Long-term exposure caused kidney effects
with oxalate crystal deposition; histopathological changes of the
kidneys, liver, blood vessels, testes, and sperm; and decreased
body weight.
M0000482 DuPont Page 9
Material Safety Data Sheet
(TOXICOLOGICAL INFORMATION - Continued)
No deaths occurred in animals exposed by inhalation to saturated
vapors of Ethylene Glycol. Repeated inhalation exposure caused
histopathological changes of the liver and lungs; eye irritation;
and clouding of the eye (corneal opacity).
In animal testing Ethylene Glycol has not caused carcinogenicity.
Reproductive data on adult animals show interference with
reproduction only at levels which produce other toxic effects in
the adult animal. Tests have shown Ethylene Glycol to cause
developmental toxicity in animals. Ethylene Glycol has not
produced genetic damage in bacterial cultures. There are reports
indicating that Ethylene Glycol does not produce genetic damage in
some animal or mammalian cell culture tests; however, there are
reports in the literature that suggest positive results.
S-Metolachlor
Animal testing indicates that S-Metolachlor did not cause
reproductive/developmental effects. S-Metolachlor was found
not to cause mutagenicity. Benign liver tumors were
observed at high dose levels in female rats.
