Description

Liquid with a fishy odor; [Merck Index] Yellow liquid; [MSDSonline]

Sources/Uses

Used as systemic insecticide and acaricide mainly for ornamental and non-food crops; [HSDB]

Comments

Very toxic cholinesterase inhibitor; [Merck Index] “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]

No longer registered as a pesticide for use in the US; [HSDB]

Biomedical References

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]
