摘要:
分析24条环太湖主要进出河流河口表层沉积物中Pb、Cd、Cu、Zn、Cr和Ni等6种金属含量特征,并用Hakanson潜在生态危害指数法评价其生态危害,旨在为合理预防和治理太湖重金属污染提供依据. 结果表明,对照全国土壤环境质量标准,环太湖诸河口表层沉积物中Cd、Cu和Zn普遍超标,重金属污染强度总体上是北部河流>南部河流,入湖河流>出湖河流. 潜在生态风险评价结果显示,本次监测的各河流河口都不同程度地受到重金属污染,以蠡河河口污染最重,达到很强生态危害. 各重金属对太湖生态风险影响程度从高到低依次为Cd>Cu>Pb>Ni>Zn>Cr. 图5 表2 参17
Abstract:
To provide basic information for controlling heavy metal pollution of the Taihu Lake in China, the concentrations of six heavy metals (Pb, Cd, Cu, Zn, Cr and Ni) in surface sediments of the river estuaries of 24 main inflow and outflow rivers around the Taihu Lake were investigated, and the potential ecological risk of the heavy metal pollution were assessed using Hakanson ecological risk index. The results showed that, based on the Environmental Quality Standards for Soils of China, the river estuaries around the Taihu Lake were mainly polluted by Cd, Cu and Zn, and the overall intensity order of the heavy metal pollution was: northern rivers > southern ones, and inflow rivers > outflow ones. Based on the potential ecological risk assessment results, the monitored river estuaries were all contaminated to different degrees, of which the Li River was contaminated most seriously with a very high ecological risk. The ecological risk of the pollution by different heavy metals varied in the descending order of Cd, Cu, Pb, Ni, Zn and Cr. Fig 5, Tab 2, Ref 17
