- Abstract:
-
The investigation of Hanyuan lead-zinc mine areas in Sichuan province showed that lead and zinc pollution in the soil were serious,and the concentrations of lead and zinc had been more than third step of national standards.Among 14 preponderant plants in mine areas,just Pseudostellaria maximowicziana was the lead enrichment-plant.It was 728.3mg/kg lead in shoots,while the lead bio-concentration coefficient of shoots was 0.76 and the lead translocation coefficient was 0.81.Pseudostellaria maximowicziana reached the standard of enrichment-plant,which the lead content in shoots is more than 500mg/kg,and the lead bio-concentration coefficient of shoots is more than 0.6,and the lead translocation coefficient is more than 0.6.Therefore,Pseudostellaria maximowicziana can be used as alternative material of soil lead pollution remediation in lead-zinc mine areas.
