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. ...

VaCure Mercury stabilisation by Mobile Units

by econ industries GmbH  (Dec. 30, 2014)

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 ...

The African crested rat’s poisonous hairs studied by attenuated total reflection infrared spectroscopy case study

by Specac Limited  (Nov. 25, 2014)

Introduction Plant toxins are commonly used by many invertebrates, as an effective defence against predation. However, such behaviour has recently been observed in a mammal.1 The African crested rat, Lophiomys imhausi, applies a potent toxin to the fur alongside its flanks. It acquires this toxin from Acokanthera schimperi,1 a shrub abundant in ...

Cross‐basin comparison of mercury bioaccumulation in lake Huron lake trout emphasizes ecological characteristics

by John Wiley & Sons, Ltd.  (Nov. 17, 2014)

Understanding factors influencing mercury (Hg) bioaccumulation in fish is important for examining both ecosystem and human health. However, little is known of how differing ecosystem and biological characteristics can drive Hg bioaccumulation in top predators. This study compared and contrasted Hg bioaccumulation in multiple age classes of ...

Mercury‐contaminated terrestrial spiders pose a potential risk to songbirds at Caddo Lake (Texas/Louisiana, USA)

by John Wiley & Sons, Ltd.  (Nov. 5, 2014)

Methyl mercury (MeHg) is an environmental contaminant that can have adverse effects on wildlife. Because MeHg is produced by bacteria in aquatic ecosystems, studies of MeHg contamination of food webs have historically focused on aquatic organisms. However, recent studies have shown that terrestrial organisms such as songbirds can be ...

Air Rule for Cement Kilns Requires 92 Percent Cut in Mercury Emissions

by Ohio Lumex Co., Inc.  (Nov. 1, 2014)

Portland cement kilns will be required to reduce emissions of mercury by 92 percent as part of an Environmental Protection Agency final rule announced Aug. 9 that imposes controls for several toxic pollutants. Although most of the emissions standards in the final rule are less stringent than what the agency had proposed in 2009, the cement ...

Critical review of mercury SQVs for the protection of benthic invertebrates

by John Wiley & Sons, Ltd.  (Oct. 15, 2014)

Sediment Quality Values (SQVs) are commonly used – and misused – to characterize the need for investigation, understand causes of observed effects, and derive management strategies to protect benthic invertebrates from direct toxic effects. We compiled > 40 SQVs for mercury, nearly all of which are “co‐occurrence” SQVs derived from databases of ...
