Farming of carnivorous livestock for pelts has the potential to contaminate nearby ecosystems because animal feed and waste potentially contain persistent organic pollutants (POPs) and metals. Mink farms in Nova Scotia (NS), Canada, provide livestock with feed partially composed of marine fish...

Hg contamination in soil is an increasing global concern. Rhizosphere technology to remediate Hg pollution is direction of future work. Brassica juncea had been widely used for Hg contaminated soil remediation. However, the effects of Hg pollution to rhizobacteria of B. juncea has rarely...

Environmentally benign sustainable origin greener sorbents for removing diverse pollutants in water are in huge demand to reduce pollution worldwide. Furthermore, heterogeneous nature and varied existence of pollutants, metal ions are dissolved in water while oil floats, demands a one-step...

Artisanal and small scale gold mining (ASGM) is a major source of anthropogenic mercury (Hg) to the environment globally, and to West Africa, and these inputs have led to environmental contamination and human exposure. While studies have documented the effects of Hg inputs in West Africa, there...

As of late 2020, the Trump administration had initiated almost one hundred rollbacks of U.S. environmental regulations. A careful assessment of the benefits and costs of rolling back an existing regulation can and should inform such decisions. When assessing the potential rollback of an existing...

The 2013 Minamata Convention on Mercury (Convention) is the world’s newest and most ambitious multilateral environmental agreement (MEA). In addition to making a significant step forward in addressing mercury pollution, the Convention also marks a shift in environmental treaty-making. With...

"Both large-scale and small-scale mining operations are found in the rainforests of South America. But while the large-scale operations largely comply with the legal and regulatory framework provided by the different governments of the Amazon Countries, the small-scale mining operations fall...

Mercury (chemical symbol Hg) is a heavy metal occurring on earth in various forms. It can be converted from one form to another by natural processes, and, once released, actively cycles in the environment for hundreds to thousands of years before being buried in sediment. It is well known for...

This report describes work conducted by the European Commission's Joint Research Centre in the contest of GMOS (Global Mercury Observation System). GMOS is an FP VII funded large-scale collaborative project aiming at the establishment of a Global Mercury Observation System including ocean-based,...

Mercury has been one of the most persistent cases in contemporary history of international market regulations and this in spite of its having been affected by important technological changes and the regular discovery of new deposits. This paper offers an approach to the least known period,...

Assessing the welfare impact of consumer health advisories is a thorny task. Recently, Shimshack and Ward (2010) studied how U.S. households responded to FDA’s 2001 mercury-in-fish advisory. They found that the average at-risk household reduced fish consumption by about 24%, resulting in a...

Several recent studies have used simulation models to quantify the potential effects of recent environmental regulations on power plants, including the Mercury and Air Toxics Standards (MATS), one of the US Environmental Protection Agency’s most expensive regulations. These studies have...

This paper gives an overview of economic assessments of the benefits of the control of emissions of mercury compounds, discusses their completeness from a social cost point of view, and discusses the relative magnitudes of the values attached to mercury compounds in different contexts. The...

Certain energy-saving light bulbs, namely compact fluorescent lamps (CFLs), are widely available on the market and are offered for saving electricity and, eventually, reducing carbon dioxide emissions particularly from coal-fired power plants. They fulfil the requirements of Commission...

This paper describes a probabilistic assessment of congenital neurological risks associated with consumption of fish and shellfish containing MeHg and the effects that local coal combustion might have on those risks. Two scenarios were considered with this model: the ``baseline`` scenario (MeHg...

В статье обосновывается необходимость разработки методологии экологического нормирования. Проведен анализ содержания тяжелых металлов в водных экосистемах...

The conventional economic wisdom is that improving consumer information will enhance welfare. Yet, some scientists speculate that the Food and Drug Administration's prominent 2001 mercury in fish advisory may have harmed public health. Lower mercury intakes reduce neurological toxicity risks....

In December 2003, the U.S. Environmental Protection Agency (EPA) unveiled its long-awaited proposal for regulating mercury emissions from coal-fired utilities, which it later dubbed the quot;Clean Air Mercury Rule.quot; Methylmercury is a potent neurotoxin, leading to irreversible neurological...

The Institute for Reference Materials and Measurements (IRMM) of the Joint Research Centre (JRC), a Directorate-General of the European Commission, operates the International Measurement Evaluation Programme IMEP. It organises interlaboratory comparisons (ILC's) in support to EU policies. This...

Rtęć dość powszechnie występuje zarówno w węglu brunatnym, jak i kamiennym. Uważa się, że w substancji mineralnej węgla powiązana jest ona głównie z pirytem, a w substancji organicznej z grupami tiolowymi. Niemniej jednak spotykane są również węgle, w których rtęć w...

Recent research has shown that fly ash may catalyze the oxidation of elemental mercury and facilitate its removal. However, the nature of mercury-fly ash interaction is still unknown, and the mechanism of mercury retention in fly ash needs to be investigated more thoroughly. In this work, a fly...

We analyze the bipartisan call to ban US exports of commodity mercury. An export ban can generate positive environmental benefits by increasing the scarcity of mercury in those markets where toxic releases occur. We show, however, that a direct mercury purchase and retirement policy can achieve...

Density functional theory calculations are performed to provide a molecular-level understanding of the mechanism of mercury adsorption on sulfuric acid-impregnated carbonaceous surface. The carbonaceous surface is modeled by a nine-fused benzene ring in which its edge carbon atoms on the upper...

Assessing the welfare impact of consumer health advisories is a thorny task. Recently, Shimshack and Ward (2010) studied how U.S. households responded to FDA's 2001 mercury-in-fish advisory. They found that the average at-risk household reduced fish consumption by 21%, resulting in a...

The wet flue gas desulfurization process (FGD) in fossil fired power plants offers the advantage of simultaneously removing SO2 and other water soluble pollutants, such as certain oxidized mercury compounds (Hg2+). In order to maximize SO2 removal efficiency of installed FGD units, organic...

The performance of electrocoagulation with iron, aluminum and hybrid Al/Fe sacrificial electrodes for the removal of mercury from pharmaceutical wastewaters was investigated. Operational parameters such as pH, current density, contact time and metal ion concentrations were studied to achieve the...

Mercury pollution poses global human health and environmental risks. Although mercury is naturally present in the environment, human activities, such as coal burning, have increased the amount of mercury cycling among the land, atmosphere, and ocean by a factor of three to five. Emitted to the...

After a pair of toxic releases in Bhopal, India and Institute, West Virginia in the 1980s, environmental groups and members of the public demanded more information on toxic chemical releases into the community. As a result, United States facilities that manufacture, use, or process...

This paper examines responses to a national FDA advisory that urged at-risk individuals to limit store-bought fish consumption due to the dangers of methyl-mercury. We investigate consumer response using both parametric and nonparametric methods. Some targeted consumers significantly reduced...
