| 摘 要： | 概要地回顾了近年来国内外湖泊沉积物中重金属环境污染方面的研究成果,介绍了湖相沉积物重金属研究的主要内容、方法和可能的发展方向。认为就重金属成因方面应加强区分其主要来源是岩石和矿物风化的碎屑产物、大气降尘、人类活动等的研究;重金属污染方面更应重视污染物质的生物有效性、迁移转化机理和重金属“二次污染”的研究;研究手段上,注重运用同位素示踪与定年技术来研究重金属的来源和污染历史,应用高分辨率沉积物钻心研究环境的变迁。最后提出加强多学科的综合研究,建立中国湖泊基准数据库,为探讨湖泊湿地的可持续发展提供依据。

| Abstract: | This paper briefly reviews the results obtained in the study of environmental pollution by heavy metals in domestic and foreign lake sediments in recent years and introduces the main content,research approaches and possible directions in the study of heavy metals in lake sediments.Then it makes the following suggests:in respect to the origin of heavy metals,efforts should be strengthened to distinguish the main sources from the detrital product of weathering of rocks and minerals,dust falls and human activities;for heavy metals pollution,more attention should paid to the bioavailability and mechanism of remobilization of pollutants and "secondary pollution" of heavy metals;for the research means,importance should be attached to applications of isotope tracing and dating techniques in the study of the sources and pollution case histories of heavy metals and the high-resolution sediment cores in the study of environmental changes.Finally,the authors suggest that we should strengthen multidisciplinary comprehensive research and establish a basic database of Chinese lakes in order to provide a basis for the sustainable development of lake and wetland research. |
