2. The concentration of toluene in breathing zone was significantly increased at that of hippuric acid in urine was increased (P<0.01) but working duration was not statistically different from urinary hippuric acid. (P>0.1).
3. The concentrations of toluene and hippuric acid were higher in work places with local ventilation system than in workplaces without such a system. (P<0.01).
4. The complained rates of subjective symptoms were 72% in headache, 58% in eye problem, 54% in dizziness, 48% in abnormal sensation of skin. 44% in breathing problem and 36% in throat problem. They were not statistically different from urinary
