海南岛主要河流水体中重金属元素迁移富集特征

Migration and Enrichment Characteristics of Heavy Metal Element in the Main River Water of Hainan Island

河流体系中的重金属元素主要存在于悬浮颗粒物、溶解相和沉积物三部分中。选择海南岛12条主要河流,分别在丰水期和枯水期采集过滤水、悬浮物及水系沉积物样品,分析重金属元素在过滤水、悬浮物及水系沉积物中的含量特征,总结水体中重金属元素的地球化学迁移方式及富集特征,查明重金属元素迁移富集的主要影响因素。

The heavy metal in the river-system is mainly distributed in the suspended particulate matter in the dissolved phase and sediments of three parts.To select the 12 major rivers in Hainan Island,the article collected the filtered water,suspended solids and stream sediment samples in the wet and dry seasons,analyzed the characteristics Concentration of heavy metals in filtered water,suspended solids and stream sediments,summed up the elements of heavy metal geochemical migration patterns and enrichment features,identify the main factors affecting migration and enrichment in heavy metals.
