The results showed that 206Pb/207Pb, 208Pb/204Pb and 206Pb/204Pb of soil samples were all remarkably correlated linearly with reciprocals of Pb concentration, and 206Pb/204Pb had a significant positive linear correlation with 208Pb/204Pb, which was consistent with binary mixing model.

结果表明，土壤样品206Pb/207Pb、 208Pb/204Pb和206Pb/204Pb与Pb浓度的倒数，206Pb/204Pb与208Pb/204Pb都呈显著的线性正相关关系，这些关系符合二元混合模型，由此可以推断土壤铅主要源于人为排放和土壤母质。
