TOXICOLOGICAL INFORMATION
----------------------------------------------------------------------
# Animal Data
CIMARRON MAX PART A:
Oral LD50: > 5000 mg/kg in rats
(Very low toxicity)
Skin LD50: > 2000 mg/kg in rabbits
(Slight to moderate toxicity)
CIMARRON MAX PART A is a slight eye irritant, but is not a
skin irritant or skin sensitizer in animal tests.
Metsulfuron Methyl
Inhalation LC50, 4 hr: > 5.3 mg/L in rats
(Very low toxicity)
Single exposures of animals to Metsulfuron Methyl by
inhalation caused body weight loss and other nonspecific
effects.
Repeated applications of Metsulfuron Methyl to the skin of
rabbits caused skin irritation, but no other changes were
observed.
Repeated oral doses of Metsulfuron Methyl produced decreased
body weight gain and decreased liver weights when compared
to the control group. Long term administration caused body
weight loss.
Animal testing indicates that Metsulfuron Methyl does not
have carcinogenic, developmental, or reproductive effects.
There is a report indicating that Metsulfuron Methyl
produced genetic damage in a mammalian cell culture test;
however, other tests with Metsulfuron Methyl in bacterial
and mammalian cell cultures and in animals did not produce
genetic damage. The weight of evidence suggests that
Metsulfuron Methyl does not cause genetic damage.
CIMARRON MAX PART B
Oral LD50: 1497 mg/kg in rats
Dermal LD50: > 2000 mg/kg in rabbits
Inhalation 4 hour LC50: > 2.07 mg/L in rats
Cimarron Max Part B is a skin irritant, and an eye corrosive
substance, but is not a skin sensitizer in animal tests.
No animal data are available to define the carcinogenicity,
developmental, reproductive or mutagenic hazards of Cimarron
M0000471 DuPont Page 8
Material Safety Data Sheet
(TOXICOLOGICAL INFORMATION - Continued)
Max Part B.
(2,4-D)
Repeated ingestion of 2,4-D by rats caused decreased growth
rate, clinical chemical changes, and kidney effects. In a
different study in rats, effects included increased kidney
and thyroid weights, clinical chemical changes and
histopathological changes in the kidneys. Repeated
ingestion of 2,4-D by mice caused kidney effects, and
increased kidney, pituitary and adrenal weights. Several
long-term ingestion studies in rats, dogs, or mice resulted
in no significant toxicological effects. In other long-term
studies in rats and mice, 2,4-D caused kidney effects in
mice; and decreased body weights, kidney effects,
hematological changes and thyroid/parathyroid changes in
rats.
Several chronic feeding studies with 2,4-D resulted in no
carcinogenicity in rats, dogs and mice. Although in one
study there were brain tumors at 45 mg/kg in male rats, a
subsequent study failed to duplicate these lesions at doses
up to and including 150 mg/kg/day.
Developmental, reproductive and mutagenicity studies with
2,4-D have produced both positive and negative results.
