湖泊沉积物质量基准研究进展

当前湖泊沉积物污染问题日益引起广泛关注,建立切实可行的沉积物环境质量基准,是对受污染沉积物进行科学评价和有效治理的重要前提。本论文介绍了沉积物质量基准的概念和国内外在该领域的最新研究进展,阐述了建立沉积物质量基准的主要方法,并对当前沉积物质量基准存在的关键问题和未来研究前景进行了分析。作者认为,当前亟待开展复合污染条件下的沉积物环境质量基准研究,应注重数值型沉积物质量基准和生物响应型沉积物质量基准的有机结合,加快建立沉积物毒性试验的标准方法体系,加强沉积物污染物的赋存形态与迁移转化规律研究,探索建立符合我国区域特点的沉积物质量基准理论、技术和方法体系,提高沉积物质量基准的准确性、针对性和适用性。

Progress in Research on Lake Sediment Quality Guidelines

The problem of lake sediment pollution has attracted wide attention.To establish the feasible sediment quality guidelines(SQGs) is an important precondition for scientific evaluation and effective governance of polluted sediments.This paper describes the concept,developing trend and how to establish the methods of SQGs,and points out the key scientific problems and the prospects of SQGs.It is necessary to establish a sediment toxicity test standards system as soon as possible,to combine the Numerical Sediment Quality Guidelines closely with the Type of Biological Response to Sediment Quality Guidelines,to enhance research on the speciation,migration and transformation of the pollutants in sediments,to explore the SQGs under combined pollution conditions,and establish the theoretical,technological and methodological systems of SQGs adaptable to the regional characteristics in China.
