Potential Ecological Risk Assessment of Heavy Metals in Substrate of Zhalong Wetland
摘要
Abstract
By in-situ investigation and datum analysis, the contents of five typical heavy metals in the sub-strate of Zhalong wetland and in the water body were discussed. Results showed that Zhalong was a vul-nerable zone of west Songnen Plain, which had being a trend of degradation. The measured contents werefar larger than background level, which ranked as: Zn〉Cu〉Pb〉Cr〉Cd based on the measured concen-tration. In addition, the concentration ions existed obvious spatial variation as following rules, and poten-tial ecological risk index were larger where was adjacent to agricultural activity area or chemical plant, i. e.the risk index in Lindian county was above 600, and below 300 in core area. As a portion of wetland sys-tem, the rare species were influenced to some extent too. It is should be drawn enough attention for thedegradation of wetland.关键词
