摘要: This study's objectives were to evaluate the elements degree of contamination in Tajan River and status this river for future ecotoxicology studies. Based on geo-accumulation index (Igeo) factor (CF) indices, Cr, Mn, Fe, Ci, Ni Zn showed low levels at all stations, while Se a very high contamination. Potential ecological risk (Eri) (RI) indices values river, was confirmed by pollution load (PLI) results as well comparison concentrations these with mean earth's crust sediments worldwide. Overall, that cannot be regarded contaminated respect studied (with exception selenium arsenic) studies, but can considered reference river.
