河流底泥重金属污染及潜在生态风险评价——以湘江株洲段为例
Pollution and Potential Ecological Risk Assessment of Heavy Metals in River Sediments -Case Study on the Zhuzhou Section of Xiang River
摘要
Abstract
The contents of heavy metals including Pb, Zn, Cd, As, Hg and Cr in 32 sediment samples collected from the both banks of Zhuzhou section of Xiang River were analyzed, and the potential ecological risk was evaluated. It is concluded that Xiawan section concentrates the heavy metal most, where the contents of Cd, Hg and As exceeded the three standard GB15618-1995 and the background level of soils in the cities of Changsha, Xiangtan and Zhuzhou. The heavy metals distributes as the right bank higher than the left bank. The potential ecological risk of heavy metals are very high at all the monitoring spots in Zhuzhou Section of Xiang River. The influence degrees of potential ecological risk of heavy metals rank as Hg 〉 Cd 〉 As 〉 Pb 〉 Zn 〉 Cr.关键词
