Mercury – The Facts, Myths and Clean Up Tips!

by Alpha Cure (UK)  (Feb. 20, 2015)

Mercury, the facts. Mercury is an element (Hg on the periodic table) found naturally in the environment. Mercury emissions can come from both natural and man-made sources. It is commonly used in mercury arc lamps for UV curing, however this is a very minimal amount (as little as 5mg) and is used in the lamp to increase the voltage. Due to the ...

Influence of a chlor‐alkali Superfund site on mercury bioaccumulation in periphyton and Low‐trophic level fauna

by John Wiley & Sons, Ltd.  (Mar. 2, 2015)

In Berlin, NH, the Androscoggin River flows adjacent to a former chlor‐alkali facility that is a US EPA Superfund site and source of mercury (Hg) to the river. A study was conducted to determine the fate and bioaccumulation of methylmercury (MeHg) to lower trophic‐level taxa in the river. Surface sediment directly adjacent to the source showed ...

Effects of photodemethylation on the methylmercury budget of boreal Norwegian lakes

by John Wiley & Sons, Ltd.  (Feb. 7, 2015)

MeHg concentrations in freshwater fish from southeastern Norway continue to increase, highlighting the need for a comprehensive understanding of MeHg sources, cycling, and degradation in the aquatic environment. The authors assessed the importance of photodemethylation (PD) in the MeHg budget of four Norwegian lakes. PD rates (kpd) were ...

Organochlorine pesticides, lead, and mercury in northern bobwhite (Colinus virginianus) and scaled quail (Callipepla squamata) from the Rolling Plains ecoregion of Texas and Oklahoma

by John Wiley & Sons, Ltd.  (Feb. 7, 2015)

Northern bobwhite (Colinus virginianus) and scaled quail (Callipepla squamata) from the Rolling Plains ecoregion in Texas/Oklahoma were evaluated for organochlorine pesticides (OCs), Pb, and Hg. Of all OCs analyzed, only p,p'‐DDE and p,p'‐DDD were found in a few composite liver samples. Similarly, a small fraction of tissue samples had ...

Increase in mercury in Pacific yellowfin tuna

by John Wiley & Sons, Ltd.  (Feb. 2, 2015)

Mercury is a toxic trace metal that can accumulate to levels that threaten human and environmental health. Models and empirical data suggest that humans are responsible for a great deal of the mercury actively cycling in the environment at present. Thus, one might predict that the concentration of mercury in fish should have increased ...

Mercury and other trace elements in Ohio River fish collected near coal‐fired power plants: Interspecific patterns and consideration of consumption risks

by John Wiley & Sons, Ltd.  (Jan. 14, 2015)

Many coal‐fired electric generating facilities in the US are discharging higher loads of Hg, Se, and other chemicals to receiving streams due to the installation of flue gas desulfurization (FGD) air pollution control units. There are regulatory concerns about the potential increased uptake of these bioaccumulative trace elements into food ...

Modeled methylmercury exposure and risk from rice consumption for vulnerable populations in a traditional fish‐eating area in China

by John Wiley & Sons, Ltd.  (Jan. 12, 2015)

The circulation of rice from contaminated areas could escalate exposure risk from a local problem to a national issue and affect a wider population beyond the region of origin, as confirmed by the “Poison Rice Incident” in May 2013 in Guangzhou, China. In this study, the authors' established a food chain model based on the aquivalence method to ...

Interactive effects of climate change with nutrients, mercury, and freshwater acidification on key taxa in the North Atlantic Landscape Conservation Cooperative region

by John Wiley & Sons, Ltd.  (Dec. 30, 2014)

The North Atlantic Landscape Conservation Cooperative LCC (NA LCC) is a public‐private partnership that provides information to support conservation decisions that may be affected by global climate change (GCC) and other threats. The NA LCC region extends from southeast Virginia to the Canadian Maritime Provinces. Within this region, the U.S. ...

For metallic mercury separated from various different waste streams Spent catalyst from the oil & gas industry, spent activated carbon, residues from former chlorine-alkali production, drilling wastes, fluorescent lamps powder. They all have one thing in common: Elemental mercury is separated during thermal treatment. econ industries´ ...

A review of mercury concentrations in freshwater fishes of Africa: Patterns and predictors

by John Wiley & Sons, Ltd.  (Dec. 3, 2014)

The methylated form of mercury (methylmercury) is a potent neurotoxicant and a contaminant of concern for fisheries because of its potential effects on ecosystem and human health. In Africa, inland fisheries are a crucial component of food and economic security, yet little information is available on Hg contamination trends. The authors compiled ...
