abstract studies have shown that birds due to being in the high trophic levels on the ecosystems, and also high sensitivity to toxic substances are a useful indicator for the evaluation of mercury pollution. the objective of the present study was to evaluate mercury level in the feathers of turdus philomelos and turdus merula in khanikan forests as an indicator of mercury contamination. to atta...

the aim of this study is to determine of mercury levels in various internal organs of the fereydunkenar international wetland’s birds for the first time and to determine the influence of this metal on their health. this study has been done in the fereydunkenar international wetland where is the most important wetland habitat of the central areas of hyrcanian ecosystem. fereydunkenar internation...

in this investigation, the mercury content of different samples of persian gulf shrimp and fish, caspian sea fish and the samples of fish from bandar pahlavi lagoon, zarjoub river near rasht, zayandehroud river near esfahan, and karadj river near tehran were measured by flameless atomic absorption, cold vapor-technique, using standard addition method. the main purpose of this study was to inves...

In 1996-97, Academy Natural Sciences, Philadelphia (ANSP) conducted a study of mercury levels in freshwater gamefish in New Jersey. A total of 258 fish samples from 30 water bodies were analyzed. These included single fillet samples of 58 largemouth bass, 58 chain pickerel and 109 large specimens of other commonly consumed species and 32 whole-body analysis of forage fish species. The results o...

The purpose of this study was to monitor the concentrations of mercury in the edible muscle, gill, liver, and skin of common carp (Cyprinus carpio) and silver carp (Hypophthalmichthys molitrix), in the Sanandaj Gheshlagh Reservoir, Iran. Mercury concentrations were assayed using Shimadzu AA 6600 atomic absorption spectrophotometer, and the results were given as µg/g wet weight. The level of mer...

We studied the mercury contamination of 13 species of seabirds breeding on Bird Island, South Georgia, in 1998. Total mercury concentrations in body feather samples of birds caught at their breeding colonies were determined. Among the species, grey-headed albatross (8933 ng g–1) and southern giant petrel (7774 ng g–1) showed the highest, and gentoo penguin (948 ng g–1) the lowest body feather m...

In this study, the mercury level in 25 commonly consumed seafood species was identified and used to evaluate the mercury intake for Taiwan population. Total mercury concentrations were determined by using furnace-gold amalgation mercury analyzer. The results indicated that mercury concentrations of the 25 seafood species ranged from 0.002 to 0.198 mg/kg wet wt. and varied significantly across s...

Background: Mercury (Hg) is considered a global pollutant because Hg0 which is the predominant form of atmospheric Hg resides in the atmosphere for as long as 0.5 to 2 years. Mercury has many negative effects on the reproductive, respiratory, and immune systems. Methods: In this study, 24 Caspian lampreys (Caspiomyzon wagneri) were transported to the university laboratory and then stored in ...
