In situ air concentrations of gaseous elemental mercury (Hg(0)) and vegetation–atmosphere fluxes were quantified in both high (Cala Norte, CN) low-to-moderate (Alcochete, ALC) Hg-contaminated saltmarsh areas the Tagus estuary colonized by plant species Halimione portulacoides (Hp) Sarcocornia fruticosa (Sf). Atmospheric Hg(0) ranged between 1.08–18.15 ng m−3 CN 1.18–3.53 ALC. CN, most levels oc...

 Concentration of heavy and toxic metals Cu, Zn, Cd, Pb and Hg were determined in liver and muscles of Rutilus frisii kutum and their relationships with growth parameters (length, age, condition factor) and hepatosomatic index were examined. Thirty-six fish samples were collected from February through March 2009 caught by beach seine in the southwest parts of the Caspian Sea. Atomic absorption ...

Severe discharge of sewage and industrial effluents into the Persian Gulf leads to the deposition of various types of heavy metals, especially lead and mercury, in the muscles of fish. Total mercury and methylmercury contents were determined in the edible parts (muscle tissue, fillet) of two different most popular frozen fish species from the Persian Gulf to ascertain whether the concentrations...

Introduction: Vomiting is one of the most common problems during pregnancy periods which happens in 50% of the pregnant women. Hyperemesis gravidarum is a rare status that 1 out of 500 pregnant women suffer from it. Although the reason of HG is unknown, but several studies indicate a relationship between HG and helicobacter pylori . So the aim of this study was to assess the relation between...

Bioaccumulation of Cu, Zn, Hg in muscles and liver tissues of stellate sturgeon (Acipenser stellatus) from the southern Caspian Sea was measured. Effects of condition factor (CF), age and hepatosomatic index (HSI) on metal accumulation were also determined. Some 40 stellate sturgeons were collected using gill nets in winter and spring 2007-2008 from the southern shores of the Caspian S...

Mercury (Hg) is a global pollutant and poses a worldwide concern due to its high toxicity. Guizhou province is recognized as a heavily Hg-polluted area in China due to both the special geochemical background and human activities. Here an integrated overview of current knowledge on the behavior of Hg in environments, as well as human health risk with respect to Hg contaminations in Guizhou was p...

in the present work a ph-dependent cloud point extraction procedure using ph-sensitive hydrogel polymer was applied for preconcentration and spectrophotometric determination of the hg(ii) as its thio micher's ketone complex. central composite design (ccd) and response surface method were applied to design the experiments and find out the optimum conditions. four factors entitled concentration o...
