Abstract Workers spent 1h per day in contact with vegetables that had been treated with a 0.1% aqueous emulsion of methyl parathion. The pesticide is a strong inhibitor of cholinesterase activity - induces up to 50% inhibition of plasma ChEA on the first day after spraying. The rate of disappearance of methyl parathion from washings of workers' hands (daily samples for 7 days) showed that the compound degrades slowly. The minimum waiting period for safe work with methyl parathion under field conditions was determined to be 7 days.
