Category
Organophosphate Insecticides
Description
White solid; [HSDB]
Sources/Uses
Used as systemic insecticide and acaricide; Likely discontinued for pesticide use worldwide; [HSDB]
Comments
No toxic symptoms were observed in 50 day feeding study with rats at 300 ppm; [HSDB] Effects in high-dose animal studies include changes in liver weight and inhibition of true cholinesterase; [RTECS] “The average of two baseline respective cholinesterase activity determinations three days apart, with no exposures to enzyme inhibiting pesticides for at least 30 days, is recommended for each worker prior to exposure to cholinesterase inhibitors because of large inter-individual differences in published baseline values. To be established at least once a year. Removal from workplace exposures is recommended until the cholinesterase activity returns to within 20% of baseline.” [TLVs and BEIs]
