Abstract

Based on the contents and distribution of Hg and As elements in the columnar profile of soil in Beijing area, this paper discusses the migration characters, mechanism of accumulation and dissipation in lengthways, and prohes the potential danger that the migration of Hg and As elements may cause to the environment, i. e. forming the possibility of" chemical time bomb". After surveying the soil borehole in Nanyuan, we found that pH value changed acutely and contents of heavy metals increased drastically in the soil stratum from 13. 66 to 16. 00 meters depth, which is deduced as the major accumulation stratum of contamination.
- chemical time bomb,
- soil,
- mercury and arsenic
