淮南市山南新区土壤中锌含量的研究

Study of Zinc contents in soil of newly-developed Shannan District of Huainan City

为掌握淮南市山南新区土壤中锌的含量现状,并为追踪研究该区城市化后土壤中锌的污染变化提供基础数据,对该区不同区域不同深度的土壤进行采样,用盐酸-硝酸-氢氟酸-高氯酸对土样进行全消解,用火焰原子吸收法对土壤中重金属锌的含量进行了测定,对测定结果进行了统计分析,并采用多种方法对该区土壤中重金属锌进行了环境质量评价。结果表明该区土壤中Zn的含量除个别数据外,大部分处于国内正常偏低的水平。

In order to master Zinc contents current situation in soil of newly-developed Shannan District of Huainan City,and provide basic data for tracking study of zinc in soil of the area pollution change after urbanization,the soil samples were collected from different regions and depths of the area.Soil samples were treated by hydrochloric acid-nitric acid-hydrofluoric acid-perchloric acid digestion method and Zinc contents in soil were measured by flame atomic absorption spectrometry.The determined data were statistically analysed.The environmental quality of heavy metal Zinc in soil of the area was assessed by various methods.The results show that the Zn contents in the soil of the area are normal and in domestic low level except individual data.
