Abstract
Four human volunteers entered Azodrin, methyl- or ethyl-parathion-treated cotton fields for 5-hour working periods 24-hours after treatment. Foliage residue levels, and skin, clothing, inhalation, and biomedical data were obtained. Foliage residues indicated Azodrin>ethyl>methyl parathion, with degrees of clothing and hand contamination, personal absorption and effect of blood ChE corresponding with relative foliage residue levels of the three insecticides. There was no effect on ChE from exposure to methyl parathion; however, Azodrin produced a drop in RBC ChE, while ethyl parathion resulted in a slight lowering of both RBC and plasma ChE. Dermal penetration was the principal route of pesticide absorption in this work situation.
