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.
