| Abstract: | A prawn(Penaeus vannamei) farm conducted an investigation on heavy metals enriched in its sediments,based on which an environmental risk assessment was made using methods such as Nemerow composite index,Hkanson potential eco-risk index,and single factor evaluations.Concentrations in the sediment of Cu,Zn,Pb,Cd and Cr were given;assessment according to the single factor and Memerow composite index evaluations showed the sediments in the prawn farming area met the relevant national standard in terms of heavy metal contamination,yet assessment by Hkanson potential eco-risk index indicated the potential eco-risks,from slight to medium,existed.As to the potential risk,it revealed a descending order as Cd>Pb>Cu>Zn>Cr.It inferred from the correlation existed between content of Cu and that of Zn in the sediment that Cu and Zn come from applying of artificial diet and disinfector. |
