Residues of p,p'-DDT and hexachlorobenzene in human milk from Indonesian women.

Milk from Indonesian women (n = 4) was analysed for p,p'-DDT and the fungicide, hexachlorobenzene (HCB). p,p'-DDT was found in all of the samples and at levels that are amongst the highest reported anywhere in the world in 3 of the samples. HCB was found in all 4 samples, 1 sample had an exceptionally high level. The high residue of HCB suggested exposure by eating dressed grain, major environmental contamination or direct exposure when handling the fungicide. These are the first data on pesticide residues in milk from Indonesian women which demonstrate general exposure to p,p'-DDT and HCB.
