[A method for detection of volatile organic halogenated compounds in human and animal tissues (author's transl)].

A method is described which is suitable for detecting volatile halogenated hydrocarbons boiling from 60 degrees to 150 degrees C in human and animal tissues. Fried tissue samples of 10 grams are homogenized with Na2SO4. Stripped by nitrogen in an 80 degrees C water bath the compounds are sorbed on XAD-2 columns and desorbed by pentane. The pentane extract can directly be analyzed without further clean up, either by gas-liquid chromatography or by microcoulometry. Limits of detection achieved were between 6.2 X 10(-9) g/kg for carbon tetrachloride and 49 X 10(-9) g/kg for 1,1,2-trichloroethane. The recovery in human tissue is 87% as mean value.
