| 摘 要： | 为总体了解我国主要湖泊水体重金属污染现状与生态风险,本文通过历史数据收集,利用物种敏感性分布(SSD)模型与主成分分析法,分析了我国18个湖泊或水域中6种重金属(Zn、Cd、Cr、Cu、Hg和Pb)的分布情况以及其对湖泊淡水生物的潜在生态风险(PAF)和联合生态风险(ms PAF).结果表明:在18湖泊中,6种重金属在湖泊水体中的浓度由高至低依次为Zn(均值为17.06μg/L,范围为4.03~29.33μg/L)、Pb(均值为9.33μg/L,范围为0.04~33.7μg/L)、Cr(均值为5.56μg/L,范围为0.65~40.0μg/L)、Cu(均值为3.71μg/L,范围为0.02~10.2μg/L)、Cd(均值为1.17μg/L,范围为0.01~13.6μg/L)和Hg(均值为0.19μg/L,范围为0.03~1.04μg/L);18个湖泊中重金属的分布情况由3个主成分反映,F1(Cu、Zn、Hg)、F2(Pb、Cd)和F3(Cr、Cu)的贡献率分别为28.50%、24.17%和18.40%,其分布情况受经济和地域差异影响较小;SSD模型显示,不同重金属对全部淡水生物的HC5值不同,从小到大依次为CuCrHgCdPbZn,淡水生物对重金属Cu的敏感性最高,对重金属Zn的敏感性最低;将选取的18个湖泊按ms PAF排序,由高到低依次为呼伦湖(67.0%)鲁湖(56.7%)洱海(52.7%)金银湖(52.3%)太湖(40.5%)墨水湖(39.3%)滆湖(30.2%)鄱阳湖(26.8%)洪泽湖(23.1%)高宝卲伯湖(22.4%)巢湖(20.7%)乌梁素海(19.7%)东湖(19.1%)梁子湖(4.0%)汤逊湖(2.0%)洞庭湖(1%)洪湖(0)=骆马湖(0).研究结果对于了解我国淡水湖泊水质现状和环境安全风险具有重要意义,为湖泊的进一步保护与管理提供了一定的科学依据.
