Description:
This paper aims to make a study of the distribution patterns, the enrichment characteristics and the corresponding contamination conditions caused by the heavy metal contents in the soil-crops (soybean, corn and rice) around the coal gangue dump. Samples of soils and food crops were collected around Xinji coal gangue dump by the intercept method. The concentrations of Zn, Cu, Pb, Cd, and Cr in the soils and food crops were analyzed by inductively coupled plasma optical emission spectrometer (ICP-OES). With a contrastive analysis done with the enrichment features of the root and the transfer ability of the seeds among the different food crops. In order to evaluate the pollution condition of the three corps, the single factor pollution index and the Nemerow comprehensive index. The results showed that the soil is alkaline, and the max concentrations of Zn, Cu, Pb, Cd, Cr in the soils at the depth of 20∼60 cm, which are below the background values of Huainan soil. In the top soil (...
