Abstract
The purpose of the experiments reported here was to assemble tests sensitive enough to measure changes in psychophysiological functions in human subjects exposed to low concentrations of solvent vapors. Four concentrations of trichloro-ethylene were studied, ranging from the 1965 threshold limit value of 100 ppm upward to 500 ppm. Results showed no significant effect of 100 ppm of trichloroethylene on psychomotor performance; however, there was a progressive decline in performance with increasing trichloroethylene levels at higher concentrations. Similar experiments were performed using Freon-113 (1,1,2-trichloro-1,2,2-trifluoroethane) in concentrations ranging from 1500 ppm to 4500 ppm. No significant effect of Freon-113 on psychomotor performance was seen at 1500 ppm, but slight deterioration appeared at 2500 ppm, and progressively higher concentrations resulted in an increasing decrement in performance.Keywords
