Category
Organophosphate Insecticides
Description
Brown liquid or yellow oil. [pesticide]; [NIOSH]
Sources/Uses
Insecticide and nematicide; [HSDB]
Comments
Inhalation of high concentrations may cause CNS effects; Cholinesterase inhibitor; [ICSC] “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]
Restricted
Use as insecticide cancelled in 1994; [HSDB]
