The rate of absorption of parathion, as reflected by urinary excretion of paranitrophenol, was measured in human volunteers exposed to 2% parathion dust at different ambient temperatures. Rates of paranitrophenol excretion varied directly with temperature between 58 and 105 F. Maximum excretion occurred 5 to 6 hours following initiation of exposure. Neither depressions in cholinesterase activities nor clinical symptoms were observed following the exposures used.
