The Assessment of Heavy Metal Pollution in the Estuaries in Poyang Lake Wetland and the Edible Safety Analysis of Artemisia selengensis
摘要
Abstract
Affected by industrialization and human activities,the ecological deterioration of Poyang Lake wetland had drawn more and more social attentions. To study the pollution degree of wetland soil of Poyang Lake and the edible safety of Artemisia selengensis,the levels of Cu,Pb,Cd in soil and the content of Cd in A. selengensis collected from the estury areas in Poyang Lake wetland were surveyed.The results indicate that the estuaries of four rivers disemboguing into Poyang Lake have been polluted by heavy metals:the average com⁃prehensive pollution index is 13.92,and the average potential ecological risk index is 201.64,which is classi⁃fied as medium contamination class.A.selengensis has a strong enrichment ability viewed from the comparison of the content of Cd in A.selengensis and that in the soil.The enrichment index is 1.65 and the transfer coefficient is 2.74,which shows that Cd in A.selengensis can easily be transferred from root to shoot,which people prefer to take as an vegetable.According to The National Food Safety Standards, the content of Cd in edible part of A. selengensis is 11.70-25.70 times the standard’ s value, which means there will be a huge threat to peoples health who takes it as a food.关键词
