Abstract. We studied the total mercury concentration (T-Hg) in hair of people living Chelyabinsk. Hair analysis was combined with a survey evaluating relationships and variations among subgroups potential metal exposure predictors. determined influence factors such as age, gender, location residence, smoking, color, T-Hg contents soil, road dust, household dust well fish potato consumption diet...

BACKGROUND Some studies suggest that high levels of blood and hair mercury (Hg) increase the risk of atherothrombotic diseases, an effect that may be explained by oxidative damage to the vascular endothelium. OBJECTIVES We tested whether high Hg levels impair the vasodilating function of the vascular endothelium or increase blood pressure. METHODS We measured the association between high bl...

This study was carried out to determine the mineral concentrations in the hair and serum of normal pregnant women and hair mineral concentrations in cases of obstetric disorders. The hair mineral concentrations were analyzed by inductively coupled plasma atomic emission spectrometry. Serum mineral concentrations were analyzed by the established method. The following results and conclusions were...

Mercury pollution (MeHg) up the aquatic food chains in the Amazonian ecosystems has been a major concern in environmental health. Riverside people (ribeirinhos) along the Upper Madeira river are heavy fish eaters. Hair is the best biomarker for MeHg exposure. By assuming a constant hair growth rate, it is possible to evaluate a temporal profile of Hg exposure over the recent defined past. In th...

• Mercury exposure (blood, urine and hair) in 238 ASGM miners was assessed Colombia. A 55% of the (n = 131) had Hg/methylmercury values hair above EPA threshold. levels amalgam burners were 6 to 8-fold higher than all other miners. Fish intake, burning manipulate significant indicators Hg exposure. Exposure clearly depend on different processing activities carried out ASGM. With aim protecting ...

Proton-Induced X-ray Emission analysis (PIXE) constitutes a method for trace element analysis characterized by multielemental capability, detection limits in the low ppm-range and size resolution down towards a micrometre. In applications where the sensitivity of the Electron-Induced X-ray Emission (EIXE) analysis is not sufficient and where a spatial resolution not better than a few micrometre...

After the introduction of mercury into the process of hat making in the seventeenth century it became a notoriously dangerous occupation, especially in France, where mercury was first used. Mercurial poisoning became so common among the hatters in Victorian Britain that it is widely supposed that Lewis Carroll had the condition in mind when he invented the character of the Mad Hatter in Alice's...

Amalgamation has been used for more than 4500 years in mining processes. Mercury has been extensively used in South America by Spanish colonizers for precious metal recovery. It is estimated that between 1550 and 1880, nearly 200,000 metric tonnes of mercury was released to the environment. During the present gold rush, Brazil is first in South America and second in the world in gold production...
