    Notes: Summary Quantitative and qualitative examination of Polychlorinated Biphenyl (PCB) residues in blood of the women occupationally exposed to PCBs and of their children has been carried out. The children examined in this study have ingested their mothers' milk for periods of 0 to 3 years. The age of the children at the time of this study ranges from 0 to 13 years. The data obtained in this examination provide evidence that PCBs are retained in the children's body for many years and a longer feeding of mothers' milk tends to increase PCB levels in the blood of the children. Especially high PCB levels, 93.2 ppb (μg/kg) and 77.4 ppb are found in the blood of two children. It is found that the gas chromatographic patterns of blood PCBs of the children who have been fed on their mothers' milk for a long time, are different from those of their mothers.

    Notes: Summary Health status of the workers in dye-producing plants were examined repeatedly in winter and in summer. The items studied cover 1) diazo-positive metabolites in urine 2) methemoglobinaemia, Heinz bodies, methemoglobin reductases and anaemia, and 3) liver function. The urinary diazo-positive metabolite level in the exposed was higher than that in the non-exposed and marked a conspicuous increase in summer as compared in winter, indicating significant intake of the aromatic nitro-amino compounds, while no significant methemoglobinaemia, Heinz bodies, anaemia nor disturbed liver function was observed in any group of the examinees. The results were discussed in connection with the dose-effect relationship, and compared with the experiences in the past.
