郑州荥阳市周边土壤重金属含量垂向变化与结合态特征研究
Study on Vertical Variation in Content and Bounded Form Characteristics of Heavy Metal in Soil Around Xingyang City,Zhengzhou
摘要
Abstract
Systematically explored the vertical distribution law and characteristics of chemical bounded forms of heavy metals such as Cd,Hg,As,and Pb in the soil around Xingyang City,Zhengzhou.The results showed that Cd was significantly enriched in the surface soil(0-20 cm),with concentrations 2-3 times higher than that in the deep soil(150-200 cm)due to the influence of industrial and agricultural ac-tivities.Bounded form analysis showed that the proportion of exchangeable form of Cd was as high as 18%,with outstanding bioavailability and significant environmental risks.And Pb mainly existed in the bounded form of iron and manganese oxides(40%),which is easily activated and migrated under acidic conditions.关键词
