为了探讨镉污染对人体健康影响的指标,作者于1971春至1973年10月,先后四次对日本兵库县中部生野矿山周围地区进行了稻米含镉量和含铜量的调查。按稻米含镉置的高低,分为高污染区(稻米含镉量为0.6～1.0ppm,含铜量为6ppm)、低污染区(稻米含镉量为0.3ppm,含铜量为3ppm)、非污染区(稻米含镉量在0.1ppm以下,含铜量为2ppm)。在这些地区选择30岁以上、食用本地产稻米的农民13,052人进行了健康调查。一、稻米含镉量与排泄物之间的关系
In order to investigate the impact of cadmium pollution on human health, the author investigated the cadmium content and copper content of rice in the surrounding area of the Shengyong Mine in central part of Hyogo Prefecture, Japan from January 1971 to October 1973. According to the level of cadmium contained in rice, it is divided into high pollution area (the content of cadmium in rice is 0.6-1.0ppm, the content of copper is 6ppm), the low pollution area (the content of cadmium in rice is 0.3ppm and the content of copper is 3ppm) Non-contaminated area (the content of cadmium in rice is below 0.1ppm, the content of copper is 2ppm). In these areas 13,052 farmers over the age of 30 who consumed locally grown rice were surveyed. First, the amount of cadmium in rice and the relationship between waste
