Polychlorinated biphenyls (PCB) in four pairs of human adipose tissues obtained from the women by caesarean operation and human milk secreted from the subjects thereafter were analysed by gas-liquid chromatography, and relation of PCB compositions and contents among the samples was discussed. Though PCB in the tissues and milk were mainly composed of biphenyls substituted with four to eight chlorine atoms, PCB compositions were not always the same in different subjects. However, PCB in any pair of the tissue and milk obtained from the same subject had extremely similar composition. This means that in lactating women PCB in the milk were based on those accumulated in the tissue rather than those in the day's diet. The ratio of PCB levels in the milk to those in the related adipose tissues ranged from 1/50 to 1/100.
