Methods for measuring trichloroethanol and trichloroacetic acid in blood and urine after exposure to trichloroethylene.

by Vesterberg O, Gorczak J, Krasts M

A description is given of procedures for the analysis of trichloroethanol, conjugated trichloroethanol, and trichloroacetic acid (TCA) in blood and urine. The determination of TCA is effected by measuring its decarboxylation product chloroform. The methods depend on extraction with isooctane and subsequent analysis by gas chromatography.
