摘要: The spatial distribution characteristics of metal(loid)s (Cu, Zn, Cd, As, and Pb) in the soil a silver smelting zone located Chenzhou, Hunan province, China and their ecological toxicity were studied this paper. results showed that average concentration these yard surroundings decreased order: Pb > Cu > Zn > As > Cd, all greatly surpassed local background. In general, with increase distance from pollution source horizontal direction. addition, metal an depth. geo-accumulation index toxic unit analysis revealed was extremely contaminated Cu, As exhibited most effects area. Furthermore, soils nearby yard, higher contamination found lower geographical forms than parts terrain.
