| Abstract |
Values for potential dermal and respiratory exposure were determined for workers applying fenthion for mosquito control. Application was by hand gun power spray equipment, back-pack hand pressure sprayer and hand granular dispersal. Potential dermal exposure was much greater than potential respiratory exposure. Exposure was found to be greater during hand dispersal of dry granular formulation. Highest total dermal-respiratory exposure for any individual was calculated to be only 0.03% of a toxic dose per hour of work activity. Tests to determine hazard from smoking during application operations indicated greater contamination of cigarettes as a result of contact with unwashed hands following hand granular application than following spray application operations. There was no important change in erythrocyte cholinesterase activity; however, there was some decrease in plasma cholinesterase activity in certain workers. |
