摘　　要：对８种重金属的海洋和淡水沉积物的质量基准进行了Ｂｏｘ－Ｗｈｉｓｋｅｒ图解分析,结果表明,各国水体沉积物重金属质量基准值均在２－３个数量级范围之间变化,相差超过４－５个数量级的极大值的出现,则通常与局部区域沉积物的污染程度和实验所用测试生物的敏感性有关．同时剖析了造成基准差异性的原因,以便从总体上对我国水体沉积物质量基准的制定有所启发和借鉴．All existing currently-available sediment quality guidelines for 8 metals, which include somebeing used by regulatory authorities in some countries, were collected from different jurisdictions indifferent countries.Those guidelines developed for freshwater sediments and marine sediments aredistinguished.Through the analyses of Box-Whisker,the wide rangr of values which can be foundin the figures spans 2-3 orders of magnitude.At the same time,the reasons caused those differe-nces are also analyzed in order to be beneficial to develop sediment quality guideline in China.
