Abstract

In order to study the pollution level and leaching characters of the heavy metals in the soil of lead-zinc mining area, soil sample in a lead and zinc mine of Hunan is taken as study object. The concentration of heavy metals was analyzed byinductively coupled plasma massspectrometry after microwave digestion of soil. TCLP (toxicity characteristic leaching procedure), PBET (physiologically based extraction test) and DTPA (diethylene triamine pentacetic acid) extraction experiments of soil was conducted. Results show that concentrations of heavy metals from high to low is Zn Pb Cd Cr Cu Ni As. The highest leaching ratio of TCLP and DTPA is Cd (6.83 E-04) and Zn (1.14 E-0) respectively. The highest biological effectiveness of heavy metal in soil is Zn (0.82 mg•L-1).
