MAMMALIAN TOXICOLOGY
Acute toxicity: 1) Acute oral LD50 for rat: 7 a.i.mg/kg. 2) Acute dermal LD50 for rat: >1000 a.i.mg/kg. 3) Inhalation LC50 (4 h) for rat: 0.05 a.i. mg/L. 4) mildly-irritating to skin (rabbits). 5) mildly-irritating to eyes (rabbits). 6) Not a skin sensitiser (guinea pigs). NOEL (2 y) for rats and mice 20 mg/kg diet; (1 y) for dogs 10 mg/kg diet. Daily feeding of 100 ppm of carbofuran to pregnant rats greatly reduced the ability of the pups to survive. The lowest amount of carbofuran that proved teratogenic to mice in the mother's diet (TDlo) was 210 ug/kg (fed throughout pregnancy). No mutagenic effects have been reported in animals or bacteria. Sufficient data are available from animal studies to indicate that carbofuran does not pose a risk of cancer to humans.
ADI (JMPR) 0.002 mg/kg b.w. [1996].
Classification:
Toxicity class WHO (a.i.): Ib (Highly hazardous)
US EPA Classification (formulation): I, II (Danger - Highly toxic, Warning - Moderately toxic)
EC Risk Classification: T+ - Very toxic: R26/28; N - Dangerous for the environment: R50, R53
ECOTOXICOLOGY

Effect on aquatic invertebrates: high toxicity to aquatic invertebrates, acute 48 hour EC50 for Daphnia magna is 0.0094 a.i.mg/L. Effect on algae: moderate toxicity to algae, acute 72 hour EC50 for Pseudokirchneriella subcapitata is 6.5 a.i.mg/L. Effect on honeybees: high toxicity to honeybees, contact acute 48 hour LD50 is 0.036 a.i.μg/bee; Oral acute 48 hour LD50 is 0.05 a.i.μg/bee. Effect on earthworms: moderate toxicity to earthworms, acute 14 day LC50 for Eisenia foetida is 224 a.i.mg/kg.
ENVIRONMENTAL FATE
Carbofuran's production may result in its release to the environment through various waste streams; its use as an insecticide will result in its direct release to the environment. If released to air, a vapor pressure of 5.4×10-7 mm Hg at 25 deg C indicates carbofuran will exist in both the vapor and particulate phases in the atmosphere. Vapor-phase carbofuran will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 14 hours. Particulate-phase carbofuran will be removed from the atmosphere by wet or dry deposition. Carbofuran strongly absorbs light at wavelengths between 295 and 305 nm and, therefore, may be susceptible to direct photolysis by sunlight. If released to soil, carbofuran is expected to have very high to high mobility based upon Koc values of 7.3 to 123. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 4.5×10-10 atm-cu m/mole. Carbofuran is not expected to volatilize from dry soil surfaces based upon its vapor pressure. The half-life of carbofuran in soil has been reported as 11-75 days. Experimental data indicate that carbofuran degrades faster in soil that has previously been treated with carbofuran or other pesticides. If released into water, carbofuran is not expected to adsorb to suspended solids and sediment based upon the Koc values. Carbofuran dissipation from paddy water was rapid with an estimated half-life of 3 days and a 95% removal time of 13 days; dissipation was due to both hydrolysis and biodegradation. The aqueous hydrolysis half-life at 27 deg C was found to be 5.1 weeks at pH 7.0 and 1.2 hours at pH 10. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant. A BCF of 117 using Tilapia nilotica suggests bioconcentration in aquatic organisms is high. The half-lives for degradation of carbofuran in river, lake, and seawater following irradiation with sunlight were approximately 2, 6, and 12 hours, respectively; it was not reported whether the degradation was due to direct photolysis, indirect photooxidation or other processes.
