Abstract
Mechanical cotton picker operator exposures to s,s,s-tributyl phosphorotrithioate (78488) (DEF) were characterized by an industrial hygiene survey of the mechanical cotton picking operations conducted by Schletz Brothers, on the Davis Ranch (SIC- respiratory samples were collected using a 37 millimeter glass fiber filter and an impinger pump. Dermal samples were collected on 4 inch square gauze pads attached to the operators' clothing. All samples were analyzed by gas chromatography. Respiratory samples contained 15.0 to 232.5 nanograms per cubic meter DEF and the two dermal samples contained 0.32 and 1.02 milligrams DEF for an 8 hour period. Sampling was conducted after heavy rains, when the weather was overcast and humid. The author notes that no standards have been established for occupational exposure to DEF. Further sampling is recommended during more typical weather conditions conducive to greater exposure concentrations.
