title: The metabolism of trichloroethylene and its metabolites in the perfused liver.
abstract: The metabolism of trichloroethylene (TRI) and its metabolites, chloral hydrate (CH), trichloroethanol (free-TCE) and trichloroacetic acid (TCA), were examined in the isolated perfused rat liver, to clarify the role of the liver in the metabolism of TRI. TRI was rapidly converted to TCE and TCA by the perfused liver. TCA was produced from TRI about 2.5 times greater than was total-TCE. CH was metabolized to TCE and TCA immediately. TCA was also a dominant metabolite of CH over total-TCE. TCE(free type) was speedily conjugated by the liver. A portion of TCE was converted to TCA. Less than 10% of these metabolites produced by the liver were excreted into the bile. Most of them appeared in the perfusate.
