[A new approach to setting hygienic pesticide standards].

Studies are performed on tobacco-pickers, which are in contact with dimethoate and tomato-pickers, sprayed with methylparathion. The content of pesticides in washes from leaves and hands, as well as inhibitors and cholinesterase activity in serum and erythrocytes is measured. A correlation is found between the organophosphate pesticides content on vegetable material and hand wash and presence of inhibitors in blood. Proposal is made for defining the quantity of pesticides and its metabolites in hand wash when no effect is observed to be determined by coefficients, characterizing the quality of hydrolytic inhibitors in erythrocytes and serum and the rate of cholinesterase activity decrease. The control for observing the minimum reentry time for to be carried out by measuring the quantity of pesticides in hand wash.
