主　　题：Heavy metals geo-accumulation index potential ecological risk human health risk 

摘      要：Mining of minerals in Guizhou,China,where it is enriched with reserves,may lead to soil contamination with heavy *** assessed the risk of eight typical heavy metals in Guizhou soils by collecting province-wide data available in the literature and using the geo-accumulation index method,the ecological risk assessment method,and the USEPA health risk assessment *** concentrations of eight heavy metals,except for Pb and Cr,were above the background *** heavy metal pollution evaluation results showed that As,Cu,Zn,Pb,Cr,Cd,and Ni reached the pollution levels,while Hg fell into the category of moderate ***,Cu,Zn,Pb,Cr,and Ni posed low potential ecological risk,while Cd and Hg demonstrated a considerable or a very high potential ecological ***,the integrated potential ecological risk was ranked“very high.Regarding to health risk,the non-carcinogenic risks caused by heavy metals were insignificant,but the carcinogenic risk caused by As was ***,there appeared serious soil contamination of Hg and As,with the latter also being the greatest potential risk to human *** Hg and As should stay at the highest priory for remediation efforts in Guizhou soils.
