Lead, cadmium and iron concentrations in the air in an area of heavy traffic and in a residential area in Yokohama city were measured with high-volume air samplers. The mean value of lead was 0.63μg/m3, of cadmium 0.01μg/m3, and of iron 6.5μg/m3 from March, 1970, to January, 1971, in the residential area. In the heavy traffic area the highest atmospheric lead level was about 10μg/m3. The lead concentration indoors was 60-70% of that outdoors, and the amount of lead in rain water paralleled the lead concentration in the air. In the soil around Yokohama, 20-40ppm of lead was found in an almost insoluble state.The lead concentration in the urine of primary school boys was 1-136μg/l (average 37.5μg/l) with a standard deviation of 17.87. It appeared that lead concentration in the urine did not parallel that in the air.
