Category

Organophosphate Insecticides

Description

Colorless or white solid; [HSDB]

Sources/Uses

Used as fungicide to control powdery mildews; [HSDB] Used on apples and ornamentals; Discontinued by US manufacturer; [CAMEO]

Comments

Causes moderate to severe erythema and moderate edema to skin; [HSDB] A cholinesterase inhibitor; Can be absorbed through skin; [CAMEO] 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]

Exposure Assessment
BEI

Acetylcholinesterase activity in red blood cells = 70% of individual's baseline; Butylcholinesterase activity in serum or plasma = 60% of individual's baseline; Sample at end of shift; [TLVs and BEIs]
