Selection and comparison of different methods for ecological risk assessment of heavy metals in the sediments of coastal wetlands, the east Fujian, China
摘要
Abstract
Heavy metal pollution is one of the current focuses on environmental issues , and the ecological risk assessment of heavy metals is one of the most effective methods in pollution ecology .With the case study of heavy metals in surface sediments of coastal wetlands, the east Fujian, China, this paper made a comparative study on advantages and disadvantages and practicability of four common methods of risk assessment of heavy metals .The results indicated as follows .Evaluation results of the different methods were quite different .According to the assessment results of marine sediment quality criteria evaluation method , the pollution degree of four kinds of heavy metal was as following: Pb =Cd >Cu >Zn, farmland >bare beach =farm >water area =mangrove forest . Accordingto the assessment result with other 3 methods , the ecological risk of heavy metals was in the same order:all for Cd>Pb>Cu>Zn, mangrove forest>farm>water area>bare beach>farmland.However, risk rating of this 3 methods was different , The result of ecological risk was relatively low by cumulative index method , while potential ecological risk index was moderate and Nemerow index was relatively high .Each method had its own advantages and disadvantages and scope , but the potential ecological risk index was more suitable for risk assessment of heavy metals in coastal wetlands , the east Fujian, China .关键词
