Heavy Metal Concentrations and Accumulation Characteristics of Dominant Woody Plants in Iron and Lead−Zinc Tailing Areas in Jiangxi, Southeast China

Phytoremediation using woody plants can effectively reduce heavy metal (HM) concentrations in soils. However, the remediation capacity of depends greatly on plant species and soil environmental conditions. In order to evaluate HM potential from different tailing areas, accumulation characteristics roots, shoots, leaves 12 dominant native growing iron lead-zinc areas were analyzed. The results showed that Cd, As, Ni, Mn, Cr most two exceeded level normal plants. distribution elements was generally as follows: root > leaf shoot for Pb As; Cr; Zn, Mn. Cu Cd varied with type pollution areas. There significant (p < 0.05) negative correlations between available phosphorus Pb, Zn roots when heavily polluted similarly, there 0.01) readily potassium Ni roots. Based higher than average concentration HMs plants, bioconcentration factors translocation factors, some considered phytoremediation. Slash pine (Pinus elliottii) indian azalea (Rhododendron simsii) had strong enrichment abilities oriental white oak (Quercus glauca) beautiful sweetgum (Liquidambar formosana) Mn paulownia (Paulownia fortunei) Zn. listed above be used phytoremediation
