Abstract: Subjective symptoms, hematology, serum biochemistry and other clinical signs were investigated 56 dry-cleaning workers exposed to tetrachloroethylene at 20 ppm (as ageometric mean of 8-hr time-weighted average), and the results were compared with the findings in 69 non-exposed controls from the same factories. There were exposure-related increases in the prevalence of subjective symptoms during the work as well as in the past 3 month period, whereas there was no significant changes in hematology. Effects of the exposure on liver and kidney functions were also negative as judged by emission enzyme activities, BUN and creatinine in the serum.
