Abstract:

Milie tailings contailling heavy metals are an imporcant source of environment pollution. Hyperaccumulator plants have the ability to accumulatae large alnoulit of heavy nietals in their tissue, and can be used for remediation contaminated soils (pliytoren~ediation). In this work, the conce~itrationso f Pb, Zn and Cd were dctcrniined in the soil, root and shoot of plants species, that grown naturally or cultivated, on waste from lrankoo lead and zinc mine jn Isfahan. the average the total concentrations of Pb, Zn and Cd in the soil were 443 1.2,4920.8 and 36.9mg/kg, respectively. The results showed that Chenopodirrnr album L. has the maximum accumulation pf pb with 557.7 mg/kg in dry shoot. Altriplex leucoclada, a species that was planted. contained the highest levels of Zn and Cd , up to 3165 abd 13.9 mg/kg in dry shoot, respectively.
