RESUMO
This study assesses the total concentration of eight toxic metals As, Cd, Co, Cr, Cu, Ni, Pb, and Zn in the soil and plant of Salix purpurea samples collected from Mitrovica mining region in Kosovo. The concentration, accumulation and transfer from soil to roots, stem and leaves were assessed using bioconcentration factor (BCF) and translocation factor (TF). The total metal content in the soil and plant was high following the trend of Zn > Pb > Ni > Cd > Cu > As > Co > Cr. The relevance between soil and accumulation of heavy metals in Salix purpurea was assessed using correlation matrix and principal components analysis. The results indicate that Salix Purpurea can be used in phytoremediation and stabilization of soil contaminated by heavy metals.

The abundances of selected elements in different environmental compartments, namely soil, honey, and bee pollen, was determined in this study. For that purpose, sixteen soil and honey samples, and nine pollen samples were taken in the region of Mitrovica, Kosovo. The concentration of elements was measured by ICP-AES and ICP-MS. Pollution level concentrations of Pb, Zn, As, and Cd were observed in soil. The level of soil pollution was estimated by calculating pollution indices. Pb was also observed at high concentrations in honey, as was Cd and Pb in pollen. Pearson's correlation coefficients revealed mostly weak and moderate correlations of the concentrations of the eight selected elements among the soil, honey, and pollen samples. Several groups of elements with geogenic and anthropogenic origin were identified by hierarchical cluster analysis. The concentrations of selected heavy metals for soil and honey were compared to those in neighboring countries, and those for pollen with samples from Turkey, Serbia, and Jordan.
