[The gas chromatographic determination of dichlorobutenes and trichlorobutenes in washings from the skin].

A sensitive selective method of unsaturated chlorated hydrocarbons detection by means of gas chromatography in skin was worked out. The limits are: for 3,4-dichlorobutene (DCB)-1-0.0024 mu g, for 1,3 DCB-2-0.0027 mu g, for 1,4-DCB-2 (cys)-0.0024 mu g, for 1,4-DCB-2 (trans)-0.0032 mu g, for 2,3,4 trichlorobutene (TCB)-1-0.0093 mu g in analysed volume. The method can be used for the sanitary control of the skin contamination in subjects exposed to DCB and TCB.
