摘要
土壤污染比较隐蔽,处理比较棘手,对人的危害性一点也不逊于大气和水污染,特别是城市土壤重金属污染,由于城市土地的有限性,人口多等原因越来越受到人们的重视。为了解郑州典型工业区土壤重金属污染特征,选取郑州兰博尔科技有限公司、郑州正一纺织机械公司、郑州热电厂、河南中都化工有限公司附近及其住宅土壤为研究对象。结果表明典型工业区附近土壤中的Cu、Cd、Cr、Ni、Zn、Pb、As、Hg等重金属都要高于附近住宅区土壤,其中土壤中Ni的含量工业区附近及其住宅差别不大,这在其富集系数也有表现。郑州兰博尔科技有限公司附近以As为主,郑州正一纺织机械公司附近以Cd、Cr为主,郑州热电厂附近以Zn为主,河南中都化工有限公司附近以Cu为主。典型工业区附近住宅土壤性质除受所在工业产业的影响,还受周围环境的影响。
Soil pollution is not easy to find, it is also difficult to handle, and it is harmful to humans. In particular, heavy metal pollution in urban soils has attracted increasing attention due to the limited nature of urban land and the large population.In order to understand the characteristics of soil heavy metal pollution in typical industrial districts in Zhengzhou, this study selected Zhengzhou Lanboer Technology Co., Ltd. Zhengzhou Zhengyi Textile Machinery Co., Ltd., Zhengzhou Thermal Power Plant, Henan Zhongdu Chemical Co., Ltd. and its residential soil as the research object.The results showed that the heavy metals such as Cu, Cd. Cr, Ni, Zn, Pb, As, and Hg in the soil around the typical industrial area were higher than those in the nearby residential areas,the content of Ni in the soil is not very different between the industrial area and its residential area, which is also reflected in its enrichment coefficient.Zhengzhou Lanboer Technology Co., Ltd. is mainly based on As, Zhengzhou Zhengyi Textile Machinery Co., Ltd. is mainly based on Cd and Cr, Zhengzhou Power Plant is mainly based on Zn, and Henan Zhongdu Chemical Co., Ltd. is mainly based on Cu. The properties of residential soils in the vicinity of typical industrial areas are affected not only by the industrial industries in which they are located, but also by the surrounding environment.
