Assessment of Potential Ecological Hazards of Heavy Metals in the Soils in the Areas of Edible Forest Products in Xinyu City
摘要
Abstract
In order to know the heavy metals in the soils in the areas of edible forest products.Soil samples from the main areas of edible forest products(Camellia oleifera,bamboo shoots)origin in Xinyu,China were collected,and the contents of 5 heavy metals(As,Pb,Cd,Cr,Hg)were determined.With the pollution index method,pollution load index method and potential ecological hazard index method of heavy metals the potential ecological hazards of heavy metals in the soils in the areas of edible forest products in Xinyu were assessed.The results showed that the mean and maximum contents of 5 heavy metals were all within the general environmen-tal limit for production area of edible forest product(LY/f 1678—2014).The soil of individual pollution index was 0.197-0.629,the pollution load index was 0.410-0.417,the single factor potential ecological risk coefficients were less than 40,and the integrated potential ecological hazard index was less than 100 in 2 types of forest soil in 4 administrative areas in Xinyu.Therefore,the heavy metal pollution and potential ecological harm of the soil in the areas of edible forest products(Camellia oleifera,bamboo shoots)were at a low level in Xinyu,and no obvious pollution was found.关键词
