Industrial Hygiene Report of Mechanical Cotton Picker Operator Exposure to DEF at Garrett and Garrett, 17356 North Galvey, Dos Palos, California 93620.

Abstract	Mechanical cotton picker operator exposures to s,s,s-tributylphosphorotrithioate (78488) (DEF), were characterized by an industrial hygiene survey of the mechanical cotton picking operations conducted by Garrett and Garrett on the Lorenzetti farm (SIC-0722) in Dos Palos, California, on November 16 and 17, 1978. 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 operator's clothing. All samples were analyzed by gas chromatography. DEF respiratory concentrations ranged from 13.1 to 1068.4 nanograms per cubic meter, and dermal concentrations ranged from 0.74 to 1.82 milligrams 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.
