淮北市典型土壤重金属现状评价

摘要

为了解淮北市典型土壤重金属含量及人类活动对土壤中重金属含量的影响，在淮北地区5个不同地点(百善、刘桥、五铺、财校、煤师院)共采集土样30个。以淮北市土壤背景值为评价标准，分析了Cd、 Hg、 As、 Pb、 Cr、 Cu、 Zn、 Ni的含量。研究发现，相对于土壤背景值， Cd 和 Cu 增幅较大， Hg 变化最大，其余元素变化较小。而根据《土壤环境质量标准》(GB15618-2008)二级标准来看，这8种元素含量均低于二级标准。%To study the heavy metal content of typical soil and the influence by human activity in Huaibei City, five different typical place (Baishan, Liuqiao, paved, Caixiao, Coal Industry Teachers College) were selected, 30 batches samples were collected. Taking Huaibei City soil background values for the evaluation criteria, the content of Cd, Hg, as, Pb, Cr, Cu, Zn, Ni was analyzed. The results showed that the increase of Cd and Cu was larger, and the change of Hg was the largest, and the other elements were small. According to Soil Environmental Quality Standard (GB15618-2008) level 2 , the content of these 8 elements were lower than the standard two.
