Abstract |
A gas-chromatographic method for the determination of trichloroethylene metabolites in serum and urine is described. Elution patterns, calibration curves and recovery rates are given. The analytical sensitivity of gas chromatography with an electron-capture detector for trichloro-compounds was found to be superior to that of colorimetric methods. Urinary trichloroacetic and monochloroacetic acid can be determined simultaneously. Methanolic hydrogen chloride was used for methyl esterification, since diazomethane may be carcinogenic. |
