我国水体底质重金属污染研究

Study on heavy metal pollution of water body in our country

水体重金属含量与环境污染关系的研究是研究水体重金属污染与健康关系的基础。在国内,有关水体污染以及水体污染与健康关系的研究大多集中在水体有机物污染方面,尚缺乏应用环境地理学和环境卫生学相结合的方法对水体底质重金属污染的来源和历史以及对人体健康可能产生的影响做出综合性评价。介绍了磁化率和放射性同位素综合分析在评价水体重金属污染中的方法学及其原理,该技术在国内的推广和应用,将丰富我国环境卫生学研究内容和手段,使我国水体重金属污染研究水平达到一个新的高度。

It is prerequisite to learn the relationship between heavy metal contents of water body and environmental pollution for understanding the health effects of heavy metal pollution of water body. At our country, most of the studies on the water body pollution and its health effects have been focused on the organic pollutants, the comprehensive evaluation about the sources, history, and the potential health effects of heavy metal pollution of water body sediments using the combined method of environmental geography and the environmental hygiene has rarely been seen. This article introduced the methodology and principle of magnetic susceptibility and radionuclide analyses to evaluate heavy metal pollution of water body. With the wide application of this method in our country, it will not only enrich the measures in the research of environment hygiene but enhance the professional skill level in heavy metal pollution studying in out country as well.
