TOXICOLOGICAL INFORMATION
----------------------------------------------------------------------
Animal Data
Basis Gold
Oral LD50: 2245 mg/kg in rats
(Slightly toxic)
Inhalation 4 hour LC50: > 5.3 mg/L in rats
(Slightly toxic)
Basis Gold is a mild eye irritant, but is not a skin sensitizer in
animal tests.
ATRAZINE
LD50, rabbit: (Dermal) 7500-9300 mg/kg.
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.
M0000381 DuPont Page 8
Material Safety Data Sheet
(TOXICOLOGICAL INFORMATION - Continued)
The weight of evidence from bacterial and mammalian cell cultures
and from animal tests indicate atrazine does not cause genetic
damage.
NICOSULFURON
Single high inhalation exposures in animals with Nicosulfuron
caused nonspecific effects such as slight to severe weight losses.
There were no effects observed when single doses of Nicosulfuron
were applied to the skin of rabbits.
No clinical signs of toxicity, and no deaths were seen in animals
administered single oral doses of up to 11,000 mg/kg of
Nicosulfuron. In a 2-week repeated dose study in rats and mice
there were no toxicologically significant changes; the NOEL for
each study was 2200 mg/kg. There were no toxicologically
significant changes during these 90-day tests in rats, mice and
dogs. In a one-year feeding study in dogs Nicosulfuron caused
decreased body weight and increased liver weights in male dogs;
the NOEL were 147 mg/kg/day and 587 mg/kg/day for male and female
dogs, respectively.
Other laboratory animal tests indicate that nicosulfuron is
neither a carcinogen nor a reproductive or developmental toxin.
Nicosulfuron has not produced genetic damage in bacterial or
mammalian cell cultures or in animals.
RIMSULFURON
Single inhalation exposures to Rimsulfuron caused nonspecific
effects such as weight loss, and irritation.
Single dermal exposures to Rimsulfuron caused nonspecific effects
such as weight loss.
Repeated and long-term ingestion exposures with Rimsulfuron
resulted in decreased body weights, increased liver, kidney and
spleen weights, mild hematological changes, and serum chemistry
changes linked to liver effects. A repeated-dose teratogenicity
study in rabbits resulted in maternal deaths at excessive doses.
There were no effects observed in offspring. A 1-year feeding
study in dogs resulted in mild tracheal effects and an increased
incidence of spontaneous testicular lesions.
Rimsulfuron did not demonstrate carcinogenic effects in long-term
feeding studies in rats or mice. Rimsulfuron did not cause
developmental or reproductive effects in animals. Rimsulfuron did
not produce genetic damage in bacterial or mammalian cell cultures
or in animals.

DISPOSAL CONSIDERATIONS
----------------------------------------------------------------------
Waste Disposal
Treatment, storage, transportation, and disposal must be in
accordance with applicable Federal, state/provincial, and
local regulations. Pesticide, spray mixture, or rinsate
that cannot be used according to label instructions must be
disposed of according to applicable Federal, state, or
local procedures.
ENVIRONMENTAL HAZARDS
Atrazine, one of the active ingredients of DuPont "Basis
Gold", is a pesticide that can move (seep or travel)
through soil and can contaminate groundwater that may be
used as drinking water. Atrazine has been found in
M0000381 DuPont Page 10
Material Safety Data Sheet
(DISPOSAL CONSIDERATIONS - Continued)
groundwater as a result of agricultural use. Users are
advised not to apply "Basis Gold" where the water table
(groundwater) is close to the surface and where the soils
are very permeable (i.e., well drained soils such as loamy
sands). Local agricultural agencies can provide further
information on the type of soil in your area and the
location of groundwater.
Do not store, use and mix and load within 50 feet of all
wells, including abandoned wells, drainage wells, and sink
holes. Operations that involve mixing, loading, rinsing, or
washing of this product into or from pesticide handling or
application equipment or containers within 50 ft of any well
are prohibited, unless conducted on an impervious pad
constructed to withstand the weight of the heaviest load
that may be positioned on or moved across the pad. Such a
pad shall be designed and maintained to contain any product
spills or equipment leaks, container or equipment rinse or
wash water, and rain water that may fall on the pad.
Surface water shall not be allowed to either flow over or
from the pad which means the pad must be self-contained.
The pad shall be sloped to facilitate material removal. An
unroofed pad shall be of sufficient capacity to contain at a
minimum 110% of the capacity of the largest pesticide
container or application equipment on the pad. A pad that
is covered by a roof of sufficient size to completely
exclude precipitation from contact with the pad shall have a
minimum containment of 100% of the capacity of the largest
pesticide container or application equipment on the pad.
Containment capacities as described above shall be
maintained at all times. The above-specified minimum
containment capacities do not apply to vehicles when
delivering pesticide to the mixing/loading sites.
Container Disposal
Completely empty bag into application equipment.
Then dispose of empty bag in a sanitary landfill or by
incineration or, if allowed by state and local authorities, by
burning. If burned, stay out of smoke. Refer to applicable
Local, State/Provincial, and Federal Regulations, as well as
industry Standards.
Water Soluble Packaging: Do not reuse the outer box or the
resealable bags. When all water-soluble packets are used, the
outer packaging should be clean and may be disposed of in a
sanitary landfill, or by incineration, or, if allowed by state and
local authorities, by open burning. If it is burned, stay out of
smoke. If the resealable bag contacts the formulated product in
any way, the bag must be triple-rinsed with clean water. Add the
