ACUTE TOXICITY
Disulfoton is very highly toxic to all mammals by all routes of
exposure. It is labeled with a DANGER signal word. Whether absorbed
through the skin, ingested, or inhaled, early symptoms in humans may
include blurred vision, fatigue, headache, dizziness, sweating, tearing,
and salivation. Symptoms occurring at high doses include defecation,
urination, fluid accumulation in the lungs, convulsions, or coma. Death
can occur if high enough doses lead to stoppage of respiratory muscles
and/or constriction of the windpipes.
Ingestion of high doses can lead to rapid onset of effects on the
stomach while symptoms resulting from skin exposure may be delayed for
up to 12 hours. Complete recovery from acute poisoning takes at least
one week, but complete restoration of the blood to normal enzyme
(cholinestrase) levels may take up to three months (9).
The oral LD50 ranges from 6.2 to 12.5 mg/kg in male rats and from 1.9 to
2.5 mg/kg in female rats (12, 10). Weanling male rats have an oral LD50
of 5.4 mg/kg (10, 5). The dermal LD50 is 3.6 mg/kg for female rats and
15.9 mg/kg for male rats (4, 10). The inhalation LC50 for one hour is
180 ppb for male rats, and 90 ug/L for female rats (3).
CHRONIC TOXICITY
Disulfoton is rapidly absorbed through the skin. This chemical inhibits
cholinesterase, and, as a result, may affect the eyes, respiratory
system, and central nervous system (9). Continual daily absorption may
cause flu-like symptoms, loss of appetite, weakness, and uneasiness.
While repeated exposure to disulfoton may inhibit the cholinesterase
enzyme and thus interfere with the nervous system, 30-day human
exposures have not resulted in significant enzyme inhibition (10).
Workers chronically exposed to organo-phosphates, of which disulfoton is
a member, have developed irritability, delayed reaction times, anxiety,
slowness of thinking, and memory defects (9). Chronic exposure of
workers may also lead to cataracts.
Rats have survived daily doses of 0.5 mg/kg/day for 90 days. Some
studies have shown that rats can acquire a tolerance for the chemical,
so they are able to adjust to the lower cholinesterase levels resulting
from chronic lower level exposures (8).
Reproductive Effects
In a long-term reproduction study, 98.5% pure disulfoton was fed at
doses ranging from 0.05 to 0.5 mg/kg/day to both male and female albino
rats. At the high dose, the number of animals per litter was reduced by
21% in the first and third generations and a 10 to 25% lower pregnancy
rate was noted. Some third-generation litters whose parents were exposed
to this dose, developed fatty deposits and swelling in their livers.
Exposed adults and litters had a 60% to 70% inhibition of red blood cell
cholinesterase (10). This suggests that long-term exposures to high
doses of disulfoton may cause reproductive effects in humans.
Teratogenic Effects
In one study, pregnant rats were given disulfoton (98.2% pure) at doses
ranging from 0.1 to 1.0 mg/kg/day through a stomach tube during the
sensitive period of gestation. Cholinesterase activity was decreased. In
the fetuses, no developmental defects were seen except at high doses,
where incomplete bone development was noted (4, 10). In another study,
rabbits were given disulfoton (97.3% pure) during the sensitive period.
At the higher doses (1.5 and 2.0 mg/kg/day), the mothers experienced
tremors, incoordination, and death, while fetal growth was not affected
(10). These studies indicate that disulfoton is very unlikely to cause
birth defects in humans.

ECOLOGICAL EFFECTS
Disulfoton-containing products are highly toxic to cold and warm fish,
crab, shrimp, birds, and other wildlife (7, 8). The acute dietary LC50
for disulfoton in mallard ducks is 692 mg/kg, and 544 mg/kg in quail.
The EPA has stated that use of disulfoton on certain crops may pose a
risk to some aquatic and terrestrial endangered species (17).
