Abstract

The aim of present research was to determine the mercury (Hg) concentrations with regards to oxidative stress in tissues samples of Coot, Fulica atra, and Mallard, Anas platyrhynchos from the Zarivar wetland, Iran. For this reason, the superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), malondialdehyde (MDA) and total antioxidant capacity (TAC) were assayed using an ELISA microplate reader. Results showed that the mercury concentration in the F. atra and A. platyrhynchos were decreased in sequence of feather > liver > kidney > pectoral muscle. The levels of the mercury concentration in the F. atra were higher in the males than in the females; in contract, the mercury concentration level in A. platyrhynchos was higher in females than in males (except mercury in feathers). Mercury in feathers of two bird species exceeded the 5 ppm threshold for adverse effect. The findings indicated the significant differences in the mean activities of SOD, GPx, CAT, and concentrations of TAC and MDA in different tissues and both bird species (p < 0.05). Moreover, results showed that the Hg concentrations in tissues of both bird species induced the oxidative stress markers and these parameters could be useful tool to evaluate the effects of mercury pollution on birds. © 2018
