To understand the soil heavy metal pollutions nearby the Tonglvshan mine, Daye city(Hubei province, China), the soil samples and eight types of vegetables were analyzed with their Cd, Cu, Pb and As concentrations from seven sampling sites around the mine, the heavy metals’ biomagnifications and the potential risks to people’s health were also evaluated in this study. Heavy metals were analyzed by ICPMS, the biomagnification and health evaluation were performed by bioconcentration factor (BCF), Influence index of comprehensive quality (IICQ), and target hazard quotient (THQ). The results showed the soil samples have been seriously contaminated, the mean concentrations of Cd, Cu, Pb and As in soils recorded as 2.56 mg/kg, 363.23 mg/kg, 121.25 mg/kg and 35.96 mg/kg, respectively; these were 15.06, 11.83, 4.54 and 2.92 times of the provincial soil averaged backgrounds, respectively. Compared with the National Foods Contaminants Limits (GB27622012), the vegetables Cd, Cu and Pb concentrations were higher than the limits 40%, 6% and 2%, respectively, whereas the As concentrations fall within the National limit. The BCF values of soil and vegetables followed with the order of Cd > Cu > As > Pb, and the heavy metals BCF values in the leafy vegetables were all higher than the nonleafy vegetables. The IICQ of the soilvegetable system was calculated as 9.76, which accounted for critical heavy metals pollutions. People’s might be exposed to the As pollutions through the consumption of those polluted vegetables, as the THQ of As via vegetable consumption was higher than 1. The total heavy metals THQs for adult and child were 1.71 ~ 3.98 and 2.20 ~ 5.10, respectively. The people living around the Tonglvshan mine were suffering health risks through the heavy metal polluted vegetables.
