The levels of total mercury and methyl mercury were measured in 40 tuna cans prepared from Persian Gulf tuna, in Tehran, Iran during 2010. The total mercury and methyl mercury concentrations were determined with a GBC 906 AA flame atomic absorption spectrometer (FAAS) and a Thermo gas chromatograph-mass spectrometer (GC-MS), respectively. The results showed that the means of total mercury and m...

Fish contain methylmercury and the potentially protective element, selenium. Blood and brain concentrations of these elements were determined in female rats after consuming AIN-93-based diets containing 0.06 or 0.6 ppm of selenium (Se) and drinking water containing 0, 0.5, or 5 ppm of mercury as methylmercury (MeHg) for 6 or 18 months. Brain and blood concentrations of mercury and selenium were...

The present paper falls within the trend of research into interactions between various pollutants emitted anthropogenically into the environment and focuses on mercury and styrofoam debris. The study covers part of the Southern Baltic's drainage area. Apart from styrofoam and beach sand, the research involved mosses, which are bioindicators of atmospheric metal pollution. The research has shown...

The ability to accurately determine metal mercury content and identify different mercury species in solid samples is essential for developing remediation and control strategies. The aim of the present study is to characterize mercury compounds based on thermal desorption. For this purpose a series of samples was prepared and the operational parameters-heating velocity, carrier gas-were optimize...

OBJECTIVE Mercury has been suggested to have negative effects on cardiovascular health. We investigated the effects of high mercury content in hair on the risk of acute coronary events and cardiovascular and all-cause mortality in men from eastern Finland. METHODS AND RESULTS The population-based prospective Kuopio Ischaemic Heart Disease Risk Factor Study (KIHD) cohort of 1871 Finnish men ag...

Changes in urinary porphyrin excretion patterns (porphyrin profiles) during prolonged mercury exposure are attributable to mercury accumulation in the kidney and to consequent effects of Hg2+ on renal porphyrin metabolism. In the present study, we evaluated the quantitative relationship of urinary porphyrin concentrations to mobilizable renal mercury content, using the metal chelator 2,3-dimerc...

The study was carried out to determine the content of mercury in bone tissue of the proximal femur (head and neck bone) of 95 patients undergoing total hip replacement due to osteoarthritis, using CF-AFS analytical technique. Furthermore, the investigations were aimed at assessing the impact of selected factors, such as age, gender, tobacco smoking, alcohol consumption, exposure to chemical sub...

This study focussed on a comparison of the extractability of mercury in soils with two different contamination sources (a chlor-alkali plant and mining activities) and on the evaluation of the influence of specific soil properties on the behaviour of the contaminant. The method applied here did not target the identification of individual species, but instead provided information concerning the ...

In recent years, landfill and incineration of waste is considered a new mercury pollution, which is paid widespread attention by domestic and foreign scientists. This paper studies mercury pollution Characteristics in the soil around Landfill taking landfill in Huainan City for an example and using AMA 254 Advanced Mercury Analyzer produced by US LECO Company. The result shows that: mercury con...
