Abstract :

In this study nickel and vanadium heavy metals were investigated in sediments and gammarus in Gilan Province. Sampling was carried out from sediments and dominant Gammarus, from 5 stations in Gilan province, in the spring of 2016. Nickel and vanadium analysis was carried out using an ICP/MS instrument. The results were statistically analyzed using one-way ANOVA and Duncan's test. The results showed that the amount of vanadium in sediment and Gammarus was higher compared to nickel and more accumulation of both metals was observed in the western part of the province (Rudsar area) compared to the eastern part. There was no significant correlation between environmental parameters and the concentration of metals. Based on the regression equation, a weak positive correlation was found between the amount of nickel and vanadium in sediments and Gammarus, which was not significant. Comparing results with NOAA standard (2004), the amount of nickel and vanadium in the sediments of the coast of Gilan province were not higher than the permissible range.
