九里山煤矿区土壤重金属污染状况研究

为了研究煤矿的长期开采活动对矿区土壤重金属污染的影响,以河南省煤炭基地九里山矿区为试验区,科学系统地进行土壤采样,对矿区土壤中的重金属元素As,Cr,Cd,Pb,Hg进行分析。结果表明:矿区土壤重金属综合污染程度达到了Ⅲ级轻度污染。 In order to study the soil contamination caused by heavy metal in long-term mining area,taking Jiulishan coal mining area as sample which is one of coal bases of Henan Province,study the heavy metal such as As,Cr,Cd,Pb and Hg.The results show that the synthetic pollution degree reaches Ⅲ degree(slight pollution)
