The objectives of this study were threefold.
First, to examine the hepatic effects of occupational exposure to 1,1,2-trichloro-1,2,2-trifluoroethane (FC 113) using conventional and newer tests (serum bile acids) of hepatobiliary function.
Second, to assess the effects of altered work practices that included a reduced exposure to a different halogenated solvent (trichloroethylene) on the same parameters of liver function ; and finally, to gather further data to support or refute the contention that serum bile acid (SBA) levels could provide a sensitive biological marker of exposure to these solvents.
Two groups of workers (control and exposed) in an Australian steel industry participated in the study.
The exposed group (n=5-6) comprised individuals who had either exposure to FC 113 (68.2 ± 12.6 ppm) or trichloroethylene (8.9 ± 3.1 ppm) during the application of these solvents in a cleaning procedure, whereas the control group (n=7-11) was composed of nonsolvent-exposed office workers in the same company.
The initial investigation involved exposure to FC 113 while a follow-up study was undertaken after changes in work practices were made including replacement of FC 113 with trichloroethylene (TRI). (...)
