[Chlorinated hydrocarbons in breast milk].

Chlorocarbons, which are used for cleaning purposes in both the home and industry, are of growing interest with respect to environmental pollution. We have therefore, compared the concentrations of chloroform (CH CL3), carbon tetrachloride (C CL4) and tetrachloroethylene (C2 CL4), determined by gas chromatography, in breast milk from 13 puerperal mothers from Innsbruck and the surrounding Tyrol with the respective data in 20 mothers from Linz and the surrounding industrial area. In fact, no elevation in chlorocarbon levels was detected in either group.
