攀枝花公园土壤中钒的提取效果比较及潜在生态风险评价

Some different reagents were applied to extract vanadium in the soil in Panzhihua park, and the extracting efficiency was followed by EDTA > HOAc > HCl > NaNO3. The soil pollution assessment revealed that there was 35% sample sites whose vanadium content exceeded to Canadian Soil Quality Guidelines. The concentration of bioavailable vanadium extracting with EDTA was 0.220-5.603 mg/kg (average 1.517 mg/kg), and the fraction was 0.19%-3.91% (average 1.12%), and there was a slight ecological risk. However, so some countermeasures of reducing pollution of vanadium in urban park soil should be put forward.
