摘　　要：氟是人体必需的微量元素,人体长期摄入过多的氟吸收后主要沉积于骨组织中,引起骨质的改变.研究了氟在河套地区的表层土壤、深层土壤、浅层地下水、沉积柱、黄河水、底泥和悬浮物等不同介质中的分布特征,圈出氟异常区的范围.分析了河套地区氟物质的来源,认为河套地区出现不同程度的高氟区,主要与黄河及周围山区的自然物质携带和工农业生产中产生的大量氟元素进入土壤有关.Fluorine is not only a necessary trace element in the human body,and also an accumulation element.The Fluorine element will be accumulated in bone tissue of human bodies while excessive intake,which lead to the changes of bone.The paper comprehensive summarizes the Fluorine element distribution characteristics in the surface and deep soil,shallow groundwater,sediment cores,the Yellow River,bed mud and suspended particles in Hetao area,delineated the anomalies range of Fluorine element,and further analyzed source of Fluorine in Hetao area.This paper concluded that the main reason of high Fluorine element content in Hetao area is that natural materials of the Yellow River,surrounding mountains carrying Fluorine element,industrial and agricultural production adding Fluorine.
