| 摘要: |
| 对现有淡水沉积物环境质量基准进行了分类比较,通过对各种基准不同污染物的基准低值、基准高值以及灰色区域的对比分析,探讨现有基准间存在的差异以及造成差异的原因.结果表明,现有各基准低值和高值问分别存在2倍到15倍,4倍到29倍的较大差异,各基准均存在较大的灰色区域.造成差异的原因主要是影响污染物生物有效性因素的复杂性,以及基准建立方法的不确定性等. |

| Abstract: |
| Different kinds of freshwater sediment quality guidelines (SQGs) have been developed using a variety of approaches. Comparisons of lower SQGs values, upper SQGs values and the gray zones of different contaminants have been made to find and evaluate the differences among various published SQGs. The results have shown that obvious quantitative differences varied from 2 to 15 times and 4 to 29 times respectively among those lower SQGs values and upper SQGs values, and all SQGs have wide gray zones which heavily influence their applicability. The differences mainly due to the complexity of controlling factors associated with the bioavailability of various contaminants, and the uncertainties of SQGs deriving approaches. |
