Abstract :

The absorption of malathion and phosalone was followed in occupationally exposed workers by determination of residues excreted in the urine. Because of the high concentrations found in the morning urine samples, the rates of excretion of phosalone metabolites in the urine of a volunteer experimentally exposed to phosalone during one and then again during three subsequent working days were investigated. The urinary excretion of phosalone metabolites was most intense 4--5 hours after exposure. At the beginning of the next day, the metabolites were still well measureable in the urine. Blood and plasma cholinesterase activities were only slightly reduced during exposure. The analyses of 24-hour urine samples, or of urine samples taken 4--5 hours after exposure, are not suitable for the routine control of occupationally exposed persons because of sampling difficulties. Instead, analyses of samples taken immediately before and after work hours have to be performed. A systematic increase in the concentrations of pesticide residues in the morning urine should initiate more efficient and well-timed protection measures.
