Abstract：
:The present study involves the assessment of metals (Cr, Ni, Pb and Cd) in contaminated agricultural soil (CAS) and abandoned chromite-asbestos waste (CW). High concentrations of Cr and Ni were found in CW (1,121-2,802 mg Cr kg(-1); 985-1,720 mg Ni kg(-1)), which CAS (1,058-1,242 mg Cr kg(-1); 1,002-1,295 mg Ni kg(-1)). Zea mays and Oryza sativa showed significant amounts of metals in root and aerial parts. The primary factors only consider the changes in metal concentrations in soil and plant, while dynamic factor includes both changes in metal concentration and environmental processes. In spite of the high concentration of Cr present in contaminated soils and crops, significant translocation of metals (>1) were found only for Pb and Ni, when primary factor was used. When dynamic factor was used, higher translocation (>1) and bioaccumulation (>1) were found for Cr along with Pb and Ni. The current study concludes that assessment of metal toxicity in CAS and crops could be better evaluated by using both primary and dynamic factors.
