Abstract
To obtain relative exposure data for the spray rig driver applying insecticides to California citrus trees, parathion [O,O-diethylO-(4-nitrophenyl) phosphorothioate] and dimethoate [O,O dimethylS-(2-(methylamino)-2-oxoethyl) phosphorodithioate] were applied with oscillating boom and airblast spray units. Spraying conditions were varied to simulate commercial application practices. Test conditions were used which varied from providing no driver protection to that of providing charcoal-filtered air. Both singleand double-side delivery systems were employed. Gauze sponges pinned to the coveralls of the driver were used to indicate dermal exposure potential, and ethylene glycol-containing impinger type air samplers were used to indicate inhalation exposure potential. Urine samples were collected and analyzed for dialkylphosphate and thiophosphate levels.
