摘要： In this study, 12 sites including abandoned mining sites, peripheral areas of mine and urban areas were chosen for soil sampling to reveal the distribution and assess the contamination of arsenic species in soils in Daye (in the southeast Hubei province of China), the soil around city are enriched by iron and copper minerals. The concentration of total arsenic in topsoil in this area varied from 12.99 mg/kg to 63.66 mg/kg. The portion of Asap varied from 12.24% to 50.70%. In the surface soil near water, the ratio was higher than at other sites. A new assessment was established in this study, which was based on the LD50 of different valence states of arsenic and the calculated mode was transformed from the geo-accumulation index.
