background: although it is one of the most toxic nonradioactive elements, mercury is widely used in dental amalgam. mercury is a toxic element which can damage various organs such as central nervous system, renal, respiratory and hematologic systems. the adverse health impacts associated to exposure to some common sources of electromagnetic fields including laptop computers, mobile phones, mri ...

In the past, human activities often resulted in mercury releases to the biosphere with little consideration of undesirable consequences for the health of humans and wildlife. This paper outlines the pathways through which humans and wildlife are exposed to mercury. Fish consumption is the major route of exposure to methylmercury. Humans can also receive toxic doses of mercury through inhalation...

background: present study was carried out in north of iran to investigate the concentration of mercury (hg) as one of the most toxic metals in tissues of two species of birds. methods: in this study, 15 birds from coot (fulica atra) and 18 birds from cormorant (phalacrocorax carbo) were hunted in anzali and gomishan wetlands. data-analyses carried out using spss software version 17 licenced by ...

Mercury is a toxic and bio-accumulative heavy metal of global concern. While good deals of research have been conducted on the toxic effects of mercury, little is known about the mechanisms involved in the pathogenesis of male reproductive dysfunction induced by mercury. Therefore, the purpose of this study was to assess the effects and underlying mechanisms of chronic mercury exposure at low l...

Mercury is a highly toxic heavy metal and the ability of the neurotoxin methylmercury to biomagnify in the food chain is a serious concern for both public and environmental health globally. Because thousands of tons of mercury are released into the environment each year, remediation strategies are urgently needed and prompted this study. To facilitate remediation of both organic and inorganic f...

Samples of fresh and fixed tissues from infants with exomphalos treated by thiomersal application were analysed for mercury content. The results showed that thiomersal can induce blood and organ levels of organic mercury which are well in excess of the minimum toxic level in adults and fetuses. The analysis of fresh and fixed tissues must be carefully controlled against normal tissues in order ...

Seabirds are used frequently as indicators of mercury contamination in marine ecosystems, but few studies have examined the forms of mercury found in seabird tissues. Here we compare concentrations of total and organic mercury in feathers (n=5) of six sympatric nesting seabirds and in egg components of Leach's storm-petrels from Machias Seal Island, New Brunswick, Canada, during the 2006 breedi...

Mercury is one of the most toxic heavy metals, and has significant industrial and agricultural uses. These uses have led to severe localized mercury pollution. Mercury volatilization after its reduction to the metallic form by mercury-resistant bacteria has been reported as a mechanism for mercury bioremediation [Brunke, Deckwer, Frischmuth, Horn, Lunsdorf, Rhode, Rohricht, Timmis and Weppen (1...
