Dimethoate was not a skin sensitizer in guinea-pigs, but a 32.7% emulsifiable concentrate formulation induced sensitization in one of 10 guinea-pigs. Formothion (an aldehyde derivative of dimethoate, which has also been used as a pesticide in its own right, but is no longer supported by the manufacturer) was evaluated for toxicological effects in 1969 and 1973. In surface waters, dimethoate and O-desmethyl dimethoate are detected. In studies in hens given single oral doses of 20-300 mg/kg bw, omethoate did not induce delayed neurotoxicity. 0000026038 00000 n
Although a safety factor of 100 would normally be used in deriving an ADI from a study of this type, the Meeting was concerned about the possibility that reproductive performance may have been affected at 1.2 mg/kg bw per day in this study and therefore used a higher-than-normal safety factor. in rats and humans. The NOAEL for reproductive toxicity appeared to be 15 ppm (equal to 1.2 mg/kg bw per day) and that for parental toxicity was 1 ppm (equal to 0.08 mg/kg bw per day) on the basis of cholinesterase inhibition, but the Meeting noted that there was some indication that reproductive performance may have been affected at lower doses. 0000031639 00000 n

The NOAEL was 1 ppm (equivalent to 0.05 mg/kg bw per day). Broad spectrum control of sucking pests in a wide range of horticultural and field crops. Slowed conversion of dimethoate to its active metabolite omethoate is suggested by the lack of a substantial difference in BuChE inhibition (related to omethoate concentration) between patients ingesting and not ingesting alcohol, despite the higher concentrations of dimethoate in those with detectable alcohol.

After reviewing the available data on genotoxicity the Meeting concluded that although in-vitro studies indicate that dimethoate has mutagenic potential, this potential does not appear to be expressed in vivo. Omethoate (the oxygen analogue of dimethoate, which has been used as a pesticide in its own right) was evaluated for toxicological effects by the Joint Meeting in 1971, 1975, 1978, 1979, 1981, and 1985. 0000031216 00000 n

An ADI of 0-0.0003 mg/kg bw was allocated in 1985. On the basis of minimal reductions in acetylcholinesterase activity of 10-20%, the NOAEL in a 12-month study in dogs at doses of 0, 5, 20, or 125 ppm was 5 ppm, equal to 0.2 mg/kg bw per day; in rats the NOAEL in a life-span study at doses of 0, 1, 5, 25, or 100 ppm was 1 ppm, equal to 0.04 mg/kg bw per day. The liver weights of animals treated at the higher doses tended to be lower than those of the control groups; there were however no microscopic changes, and the effect is unlikely to be of toxicological significance. Toxicological criteria for setting guidance values for dietary and non-dietary exposure to dimethoate, Repeated dermal, 21 days, toxicity, rabbit, NOAEL = 1000 mg/kg bw per day (highest dose tested), Repeated oral, reproductive toxicity, rat, NOAEL = 1.2 mg/kg bw per day, reproductive toxicity NOAEL = 0.08 mg/kg
It is an irritant to the skin and mucous membranes.. Its toxicity and hazard potential are still under review because of concerns about its safety.
