Mercury pollution in three species of waders from Shadegan wetlands at the head of the Persian Gulf.
Persian Gulf supports diverse ecosystems and biota in need of remediation and protection, and metal data from this region is needed. Mercury (Hg) in tissues of three waders (Black-winged Stilt Himantopus himantous, Red-wattled Plover Hoplopterus indicus, and White-tailed Plover Vanellus leucurus) from Shadegan Wetlands is reported. Black-winged Stilt had higher Hg in feather (6.6 +/- 0.6 microg/g dry weight), liver (3.5 +/- 1 microg/g dry weight), kidney (4.5 +/- 0.8 microg/g dry weight) and muscle (1.2 +/- 0.2 microg/g dry weight) (not statistically significant). Differences in Hg among waders could have resulted from diverse feeding habitats and dissimilar foraging sites.
