太湖沿岸湖区底泥重金属污染分布特征及生态风险评价OACSTPCD
Distribution Characteristics and Ecological Risk Assessment of Heavy Metals in Sediments in Coastal Area of Taihu Lake
为进一步探究太湖底泥污染状况及环境治理措施,研究以太湖各沿岸湖区底泥重金属为研究对象,通过测定229个样点底泥中8种重金属的含量,分析了其分布特征、来源及生态风险.结果显示,太湖表层底泥中Zn、Cr、Ni、Cu、Pb、As、Cd、Hg 的平均值分别为(126.86±73.31)、(90.25±47.66)、(44.62±24.30)、(39.36±28.46)、(36.86±7.84)、(11.65±5.33)、(0.86±1.31)、(0.08…查看全部>>
To further explore the pollution status and environmental treatment measures of the sediments in Taihu Lake,this study monitored the contents of eight heavy metals in the sediments of 229 sampling points in different bays of Taihu Lake,analyzed their distribution characteristics,sources and ecological risks.The results showed that the average content of Zn,Cr,Ni,Cu,Pb,As,Cd,Hg in the surface sediments of Taihu Lake was(126.86±73.31),(90.25±47.66),(44.62±24.3…查看全部>>
