The objective of this study was to examine the correlation between personal exposure of toluene at workplace and the concentration of hippuric acid in urine of male solvent workers. The study groups are 60 toluene exposed workers who worked at video tape factory and printing factory. The results are as follows: 1. The coefficient of correlation between toluene concentration of personal exposure and concentration of urinary hippuric acid was 0.649 (regression equation Y=0.015X+0.936, Y=urinary hippuric acid concentration, X=Toluene concentration of personal exposure). 2. Urinary hippuric acid concentration of workers with TLV 100 ppm of toluene was calculated 2.44 g/L by the regression equation (Y=0.015X+0.936).
Key words: Toluene; Hippuric acid
