Title Cholinesterase activity depression among California agricultural pesticide applicators
Bibliographic information 1989, Vol.15, No.2, p.143-150. Bibl.
Abstract Cholinesterase activity measurements in California of 542 agricultural pesticide applicators under medical supervision during the first 9 months of 1985 were analysed. 26 workers, 4.8% of the sample, had cholinesterase values at or below the California threshold values for removal from continued exposure to cholinesterase inhibiting pesticides (60% of baseline for red blood cell cholinesterase and 50% of baseline for plasma cholinesterase activity). Eight of these 26 workers, 31.5% had pesticide-related illnesses. Pesticides most frequently associated with cholinesterase depressions exceeding California threshold values included mevinphos (Phosdrin), oxydemeton methyl (Metasystox-R), methomyl (Lannate), and acephate (Orthene); these pesticides included organophosphates in toxicity categories I and II and one carbamate in toxicity category I.
