Mercury concentration in the feathers of birds from various trophic levels in Fereydunkenar International wetland (Iran)

摘要: Mercury (Hg) is one of the main global pollutants that may biomagnify in food nets, especially wetlands. Birds be useful biomonitoring Hg such habitats and even serve vivo samples. This paper examined concentration feathers seven bird species foraging on Fereydunkenar International wetland (in 2013). Mean concentrations found ranged from 0.005 ± 0.002 μg g−1 d.w. (dry weight) (Common hoopoe) to 0.38 ± 0.047 μg g−1 (Greylag goose). Significant differences were noted between as well trophic levels (one-way ANOVAs, p  Northern pintail ≥ Gadwall Mallard > Eurasian bittern Little Common hoopoe. The position chain significantly influenced concentrations, which highest omnivorous species. also depend migration routes breeding habitats, but evaluation exposure exceeds ambit this paper. generally low, lower than safe thresholds reported literature.
