Study on Heavy Metal Pollution in Waters of Aquaculture in Poyang Lake Region

HU Chun-hua et al(Key Lab of Environment and Bio-resource Utilization of Poyang Lake,Ministry of Education,Nanchang University,Nanchang,Jiangxi 330029)  
[Objective] The study aimed to understand the pollution statue of heavy metal in aquaculture waters in Poyang Lake and its risk degree.[Method] Based on the analysis of the present situation of aquaculture water pollution in Poyang Lake district,a comprehensive evaluation analysis was made on the pollution of heavy metal in the water body and the deposit of Poyang Lake aquaculture by using single item pollution exponent method and the ecology risk exponent method of Hakanson.[Result] Looking from the pollution degree in sampled sites,the sediment pollution in the aquaculture of Poyang Lake region belonged to the low-pollution.The analysis on the total potential risk of RI showed that the potential risk exponents of fish and crabs aquaculture waters were higher than 150,except of part mussels area,indicating that the potential risk of the heavy metal pollution in the deposit of Poyang Lake waters was at low level of ecology risk.The impact degree of the various pollutants on the ecological risk of this waters was in order of CuCd PbZn.The total potential risk degree of the aquaculture waters with different types was in order of musselsfishcrabs.[Conclusion] The heavy metal content in the aquaculture waters of Poyang Lake region was lower and its pollution belonged to the security level
