Evaluation of the bioavailability and pollution indexes of some toxic metals in polluted soils from an abandoned mining area

Abstract

The paper presents soil quality assessment using pollution and bioavailability indexes in order to highlight possible pollution generated by a decommissioned mining area in Certej, Deva County, Romania. Metals such as Cd, Cr, Cu, Ni, Pb and Zn were analyzed in pseudo-total and mobile form and the results were correlated with the content found in the vegetation collected from the same points during a previous study. The research shows a high mobility for Ni, Pb and Zn, respectively, a moderate mobility for Cd.
