Ingestion: Oral LD50 (Rat) >2,500 mg/kg
Dermal: Dermal LD50 (rabbit) >4,000 mg/kg body weight
Inhalation: Inhalation LC50 (rat) >2.02 mg/L
Slightly toxic
Eye irritation: Mildly irritating
Dermal irritation: Mildly irritating
Skin sensitization: Not a contact sensitizer
EFFECTS OF CHRONIC EXPOSURE:
ATRAZINE:
40% of rats receiving oral doses of atrazine in 20 mg/kg/day amounts for 6 months died with signs of
respiratory distress and paralysis of the limbs. Structural and chemical changes were observed in the
brain, heart, liver, lungs, kidney, ovaries, and endocrine organs. Rats fed 5 or 25 mg/kg/day of atrazine
for 6 months exhibited growth retardation. In a 2-year study with dogs, 7.5 mg/kg/day caused decreased
food intake and increased heart and liver weights. At 75 mg/kg/day, there were decreases in food intake
and body weight gain, increased adrenal weight, lowered blood cell counts, and occasional tremors or
stiffness in the rear limbs.

METOLACHLOR:
While metolachlor is not readily absorbed by the skin, repeated dermal exposures may create skin
sensitization, especially among those who work with this substance. In rats fed metolachlor for 90 days,
no effects were noted at about 90 mg/kg/day. In a 2-year study of mice, a similar no-effect level was
found, but doses of about 300 mg/kg/day caused decreased body weight gain. No negative effects on
mortality or organ weights were observed in male or female rats at doses of 15 mg/kg/day. Exposed
females showed significantly lower weight gain and microscopic changes in their liver structure at 150
mg/kg/day.
CARCINOGENICITY:
ATRAZINE:
Atrazine did not cause tumors when mice were given oral doses of 21.5 mg/kg/day from age 1 to 4
weeks, followed by dietary doses of 82 mg/kg for an additional 17 months. Mammary tumors were
observed in rats after lifetime administration of high doses of atrazine. The available data regarding
atrazine's carcinogenic potential are inconclusive.
METOLACHLOR:
Male and female mice exposed to doses up to 100 mg/kg/day for 18 to 20 months did not develop cancer,
nor did male rats at doses of up to 150 mg/kg/day over a 2-year period. Female rats given high doses for
2 years showed a significant increase in new growths, nodules, and lesions in livers at that dose. From
these data, it seems unlikely that metolachlor is carcinogenic in humans.
MUTAGENICITY:
ATRAZINE:
The weight of evidence from more than 50 studies indicates that atrazine is not mutagenic.
METOLACHLOR:
Metolachlor tested negative in two bacterial assays. Also, no mutagenicity effects were noted in a
standard mouse test. From this evidence it is unlikely that the compound is mutagenic.
REPRODUCTIVE TOXICITY:
ATRAZINE:
Dietary doses of atrazine given to rats on days 3, 6 and 9 of gestation up to about 50 mg/kg/day caused
no adverse reproductive effects.
METOLACHLOR:
In two long-term rat reproduction studies, mating, gestation, lactation, and fertility were not affected at
doses of 50 mg/kg/day. However, pup weights and parental food consumption decreased at this low
dose. In another 2-year rat study, metolachlor caused the wasting of testicles at doses of 150 mg/kg/day.
In studies on mice, no effects were noted on fertility, or zygote or embryo survival rates after very high
single oral doses. This evidence suggests that metolachlor is not likely to have an effect on reproduction
in humans under normal circumstances.
TERATOGENICITY:
ATRAZINE:
Atrazine does not appear to be teratogenic. In mice, atrazine did not cause abnormalities in fetuses
whose dams were given doses of 46.4 mg/kg/day during days 6 through 14 of gestation.
METOLACHLOR:
Metolachlor caused no birth defects in rats at maternal doses of 300 mg/kg/day administered during
critical periods of gestation (organogenesis), although some delayed or abnormal development in
offspring was seen at this dose. A decrease in food consumption was observed in the mother. In rabbits,
a similar pattern of effects (no defects but some delayed development) was also seen at doses of up to
360 mg/kg/day. These data indicate that teratogenic and developmental effects in humans are unlikely at
expected levels of exposure.
12. ECOLOGICAL INFORMATION
ENVIRONMENTAL HAZARDS: Atrazine can travel (seep or leach) through soil and can enter groundwater,
which may be used as drinking water. Atrazine has been found in groundwater. Users are advised not to apply

atrazine to sand and loamy sand soils where the water table (groundwater) is close to the surface and where
these soils are very permeable, i.e., well drained. Your local agricultural agencies can provide further information
on the type of soil in your area and the location of ground water.

ENVIRONMENTAL FATE (provided by EXTOXNET):
ATRAZINE: Atrazine is highly persistent in soil. Chemical hydrolysis, followed by degradation by soil
microorganisms, accounts for most of the breakdown of atrazine. Hydrolysis is rapid in acidic or basic
environments, but is slower at neutral pHs. Addition of organic material increases the rate of hydrolysis. Atrazine
can persist for longer than 1 year under dry or cold conditions. Atrazine is moderately to highly mobile in soils with
low clay or organic matter content. Because it does not adsorb strongly to soil particles and has a lengthy half-life
(60 to >100 days), it has a high potential for groundwater contamination despite its moderate solubility in water.
Atrazine is moderately soluble in water. Chemical hydrolysis followed by biodegradation, may be the most
important route of disappearance from aquatic environments. Hydrolysis is rapid under acidic or basic conditions,
but is slower at neutral pH鈥檚. Atrazine is not expected to strongly adsorb to sediments. Bioconcentration and
volatilization of atrazine are not environmentally important.
METOLACHLOR: Metolachlor is moderately persistent in the soil environment. Half-lives of 15 to 70 days in
different soils have been observed. Soils with significant soil water content may show more raid breakdown. Very
little metolachlor volatilizes from the soil, and photodegradation will be a significant pathway for loss only in the
top few inches. Breakdown is mainly dependent upon microbial activity, and thus will be temperature-dependent.
Metolachlor is moderately well adsorbed by most soils. Soils with higher organic matter and clay content may
adsorb it better. It is slightly soluble in water. Extensive leaching is reported to occur, especially in soils with low
organic content. Metolachlor is highly persistent in water over a wide range of water acidity. Its half-life at 20掳 C is
more than 200 days in highly acid waters and is 97 days in highly basic waters. Metolachlor is also relatively
stable in water under natural sunlight.
13. DISPOSAL CONSIDERATIONS:
PESTICIDE DISPOSAL: Product or rinsate that cannot be used according to label instructions must be disposed
according to federal, state, or local procedures. For guidance in proper disposal methods, contact your state
pesticide or environmental control agency or the hazardous waste representative at the nearest EPA Regional
Office.
CONTAINER DISPOSAL: Triple-rinse (or equivalent) and offer for recycling or reconditioning or puncture and
dispose in a sanitary landfill, or by incineration, or by open burning, if allowed by state and local authorities. If
burned, keep out of smoke. For minor spills, leaks, etc., follow all precautions indicated on the label and clean up
immediately. Take special care to avoid contamination of equipment and facilities during cleanup procedure and
disposal of wastes.
