中国主要河口沉积物的重金属地球化学研究

近年来，河口底质沉积物，不但作为污染物的主要富集介质和重要的生物栖息场所，而且作为比水介质更稳定、更强烈的区域环境质量状态和趋势指示作用的监测要素，日益引起环境界、特别是海洋环境界的普遍兴趣和重视。中国主要河口沉积物的重金属地球化学研究近年来有了长足的进展，获得了诸多成果，这些研究成果为探讨重金属含量的分布、了解其扩散范围和河口环境污染状况等提供了重要的信息。

Heavy Metal Geochemistry of Sediments in the Main River Mouths of China

Recently,estuarine bottom sediments,a main medium for accumulation of polutants and important living place for aquatic lives,have attracted more and more attention from the environmental field especialy marine environmental field as they can show more steady and intensive regional environmental quality changes and tendency than water medium.Great progress has been made in the heavy metal geochemistry of main estuarine sediments of China,and many results have been acquired from the research.These results provide important information for the knowledge of heavy metal distribution and the understanding of the diffusion ranges and estuarine pollution.
