SENSITIZATION: This product is not expected to produce skin sensitization.
ACUTE EFFECTS FROM OVEREXPOSURE: This product is expected to have low
oral, dermal and inhalation toxicity. It is expected to be mildly irritating to the skin and eyes. Signs of
toxicity in laboratory animals included mydriasis, cyanosis, ataxia, dyspnea, lacrimation, and diarrhea.
Inhalation of aromatic hydrocarbon vapors may cause dizziness, disturbances in vision, drowsiness,
respiratory irritation, and eye, skin and mucous membrane irritation. Vomiting after ingestion of this
Page 5 of 8
STINGRAYTM AQUATIC HERBICIDE (128639-00-1-21) Date: 08/31/2004
product may cause aspiration of aromatic hydrocarbons into the lungs, which may result in fatal pulmonary
edema. Naphthalene, if ingested, may cause red blood cell hemolysis, especially in individuals with
glucose-6-phosphate dehydrogenase deficiency. In humans, ingestion of large amounts of propylene glycol
has resulted in reversible central nervous system depression including stupor, rapid breathing and heartbeat,
profuse sweating and seizures.
CHRONIC EFFECTS FROM OVEREXPOSURE: No data available for the
formulation. In studies with laboratory animals, carfentrazone-ethyl did not cause reproductive toxicity,
teratogenicity, or carcinogenicity. An overall absence of genotoxicity has been demonstrated in tests of
mutagenicity, DNA damage and chromosome aberrations. Chronic exposure to aromatic hydrocarbons may
cause headaches, dizziness, loss of sensations or feelings (such as numbness), and liver and kidney damage.
Repeated overexposure to propylene glycol can produce central nervous system depression, hemolysis and
minimal kidney damage. Naphthalene causes cataracts in humans, rats, rabbits and mice. In 2-year
inhalation studies conducted by the National Toxicology Program (NTP), there was no evidence of
carcinogenic activity of naphthalene in male mice, there was some evidence of carcinogenic activity in
female mice and there was clear evidence of carcinogenic activity in male and female rats. Inhalation
studies conducted by the International Agency for Research on Cancer (IARC) have found that there is
inadequate evidence of carcinogenicity in humans, therefore, IARC has classified naphthalene as a Group
2B (possibly carcinogenic to humans); however, IARC has found that there is sufficient evidence of
carcinogenicity in experimental animals.

12. ECOLOGICAL INFORMATION
No data available for the formulation. Data presented below are based on the active ingredient.
ENVIRONMENTAL DATA: Carfentrazone-ethyl is rapidly degraded in soil (DT50 < 1.5
days) through microbial degradation, initially by hydrolysis to F8426-chloropropionic acid, and then
through further side-chain degradation to other acids. Based on field studies, carfentrazone-ethyl and its
major metabolite, F8426-chloropropionic acid, are confined to the top soil layer, indicating only slight
mobility in soil. Carfentrazone-ethyl is hydrolytically unstable in base (half-life of 5.1 hours), with stability
increasing with decreasing pH. It is susceptible to photolytic degradation in water, with a half-life of 8.3
days (pH 5). The Log Pow is 3.36 and the measured bioconcentration factor in whole fish is 159, both
indicating a low potential for accumulation. Its vapor pressure is 1.19 x 10-7 torr, indicating that volatility
is not a concern with this chemical.
ECOTOXICOLOGICAL INFORMATION: Carfentrazone-ethyl is very toxic to algae
(EC50: 5.7 to 17 礸/L), and much less toxic to fish (LC50: 1.6 to 2.0 mg/L), and aquatic crustacea (LC50 >
9.8 mg/L). Care should be taken to avoid contamination of the aquatic environment. In a test with
earthworms, carfentrazone-ethyl was shown to cause no effects at concentrations up to 820 mg/kg in soil.
Carfentrazone-ethyl shows little toxicity to birds either orally (LD50 > 2,250 mg/kg), or in the diet (LC50 >
5,620 ppm). Similarly, carfentrazone-ethyl has low toxicity to bees (no death at 200 礸/bee).
