摘要
运用概率物种敏感度分布法获得太湖水体中铜的急性水质基准值为14.57μg·L-1,慢性水质基准值为3.26μg·L-1;不同类别物种敏感性存在差异,无脊椎动物较脊椎动物更敏感,甲壳类敏感性大于鱼类。概率物种敏感度分布法与传统的物种敏感度分布法相比,更全面合理地考虑多种毒性效应,曲线拟合效果好,受数据量大小影响较小,结果更加稳定。研究结论可为铜水质标准的修订和太湖流域水环境管理提供技术支持。
Acute and chronic water quality criteria of copper for Taihu are derived to be 14.57μg·L^-1 and 3.26 μg·L^-1 by the method of probabilistic species sensitivity distribution, respectively. Moreover, the results show that invertebrates are more sensitive than vertebrates, and crustaceans are more sensitive than fishes. Our method is superior to the traditional species sensitivity distribution. In our method, the toxicity effects are considered fully and reasonably, and data are fitted more efficiently. The amount of data exhibits little effect on the results. Furthermore, the method exhibits higher stability. The results can be served as reference of wa- ter quality standard of copper in Taihu. It can provide technical support for water environment management.
