Abstract
Concentration of metals in water and sediment samples from Goranchay River was examined to obtain information about metal pollution. Also, 6 surface sediments and water samples were collected from sampling points and analyzed for metals (Na, K, Mg, Ca, Al, Cr, Mn, Fe, Ni, Co, Cu, Zn, As, Cd, Sr, Ba, Pb) using Varian model Spectra AA 220 FS atomic absorption spectrometer. The average concentration of examined metals at the same sampling locations was in line with the order of Ca>Fe>Mg>K>Na>Mn>V>Zn>Ni>Cr>Cu>Co>Pb in sediment samples. Single element pollution index values, including geo-accumulation index (Igeo), contamination factor (CF) and enrichment factor (EF), were used to evaluate contamination with metals in the examined sediment samples.
