摘要
按照中国地质调查局地质调查技术标准,采用顺序提取法研究了天津大毕庄土壤中Hg的形态分布特征,将Hg依次提取成七种形态,对其形态分布特征做了详细的分析,结果揭示出Hg在土壤中的形态主要为残渣态,非常稳定地赋存在矿物的晶格中,基本不会被生物吸收。
According to technical standard of Chinese Geological Survey,sequential extraction procedure was applied to examine the speciation and concentration of Hg in the soil of Dabizhuang Town,Tianjin Province.Seven species of Hg have been analyzed,and the bioavailability of Hg in the soil was opened out.Hg mainly exists as residual mood in soil minerals,and it is almost not bioavailable.
