Research on Heavy Metals Pollution of Farmland Soil in Mine Area
Abstract:By many experiments, the contents of heavy metals, such as Cr, Ni, Pb, Cu, Zn, Cd etc., of surface layer soil and section soil and of crops and fruits from farmland in Dongliang Mining area were detected. The correlation between heavy metals was analyzed. The situation of heavy metals pollution of soil and grain crops in this area to get pollution level was evaluated. The heavy metals vertical distribution discipline of section soil and the enrichment states of crops to heavy metals were studied, and the influence factors of heavy metals contents in rice corn were analyzed.
Keywords: mining area farmland soil heavy metal
