山东省黄河下游流域高碘地甲病分布与地球化学环境相关性

Correlation between the Distribution of High Iodin Endemic Goitre and Geochemical Environment in the Downstream Region of the Yellow River in Shandong Province

山东省黄河下游流域是山东省高碘地甲病重病区。在区域调查的基础上,选择其中的郓城、嘉祥、东昌府、博兴4县(区)开展土壤碘含量、饮水碘含量、儿童尿碘、儿童甲状腺容积、儿童甲肿率等指标调查,结果表明区内饮水碘含量和群体的尿碘含量普遍较高,高碘的危害和高碘地甲病情严重。分析了土壤、饮水碘分布及变化规律,研究了高碘地甲病与地球化学环境相关性,结果显示高碘地甲病与饮水碘含量呈正相关关系,而与土壤中碘元素含量无明显的相关关系。

The downstream region of the Yellow River in Shandong province is serious illness area of endemic fluorosis.On the basis of regional surveying,choosing 4 typical counties as studying areas,such as Yuncheng,Jiaxiang,Dongchangfu and Boxing county,the indexs of iodin content in soil,drinking water,iodin content in emiction and hypothyroid cubage and the ratio of goitre from children are studied.As showed by the results,it is indicated that the iodin content is universal higher in drinking water and emiction,the harm of high iodin and the endemic goitre due to high iodin are serious.On the basis of analyzing the distribution and the change law of iodin in soil and drinking water,the correlation between high iodin endemic goitre and geochemical environment are studied.It is showed that high iodin endemic goitre has positive correlation with iodin in drinking water,but it does not have obvious correlation with iodin in soil.
