Abstract |
The concentration and distribution of chlorinated insecticides and related materials in the blood of 10 women who had not had any occupational exposure to insecticides were determined by electron capture gas chromatography. The hexane-extractable chlorinated insecticides and related materials found in serum were p,p'-DDT (0.0077 ppm), o,p'-DDT (0.0016 ppm), p,p'-DDE (0.0152 ppm), Beta-BHC (0.0042 ppm), dieldrin (0.0013 ppm), and heptachlor epoxide (0.0008 ppm). The mean concentrations of these materials found in serum were greater than those found in the plasma, red blood cells, or whole blood. Methods for he extraction of bound chlorinated insecticides and related materials in blood were also investigated. |
