邯郸东部平原地区饮用高碘地下水对人体危害的初步研究

PRELIMINARY RESEARCH ON HARMFULNESS TO HUMAN BODY BY DRINKING HIGH IODINE CONTENT GROUNDWATER AT PLAIN AREA IN EAST HANDAN CITY

碘是与人类健康关系最密切的一种微量元素，是首批被人类确认的生命元素之一。人体含高碘或缺碘都是有害的。我们对邯郸东部平原地区８个县面积７４６４ｋｍ２的５３眼井地下水采样的测试结果发现，该地区的地下水属于含高碘地下水。碘的含量最高为６６０μｇ／Ｌ，平均含碘达１３１．３５μｇ／Ｌ。“河北省地方病”杂志１９８７年１～２期报导本地区成安县李家畈发现高碘地方性甲状腺肿。高碘对人体的危害是引发高碘甲状腺肿、高碘性甲亢、甲状腺炎、高碘诱发甲状腺癌等甲状腺疾病。因此，应积极控制高碘的摄入量，预防高碘饮水对人体的危害并积极开采高碘矿泉水用于缺碘病人补碘的治疗。

Iodine is both one of the trace elements which are closely related to human health and one of the life elements that are firstly acknowledged by human beings. Either high or low iodine content in drinking water is harmful to human body. Having researched into the sampling test result of the groundwater of obtained from 53 wells at eight counties within the area of 7464km 2 in the plain district of east Handan city, we find that the groundwater in this area belongs to the high iodine content groundwater, where its highest iodine content is 660μg/L and its average content may amount to 131 35μg/L. Some cases of high iodine endemic goiter were discovered at Li jiafan of Chengan county within the same area mentioned above, which was reported by Hebei Endemic Disease magazine, Issue No.1￣2, 1987. High iodine content in drinking water can cause high iodine goiter, high iodine hyperthyroidism, thyroiditis, even thyroid cancer and other thyroid diseases. Vigorous actions should be taken to control the assimilation of high iodine, prevent harmfulness to human bodies done by high iodine content drinking water and extract high iodine mineral water which can be used to build up iodine content in the treatment of patients who lack of iodine, thus to turn a calamity into treasure and bring benifit to mankind.
