  • Mercury

    Abstract Mercury is a naturally occurring metal found in the Earth’s crust. At high doses, mercury is known to cause adverse human health effects. Over the past several years, EPA (the Environmental Protection Agency) has focused on mercury exposures because of its potential to cause adverse human health and environmental effects, and because of its persistence and widespread distribution in the ...

  • The source and risks of mercury in the offshore industry

    Oil in Gas and RocksAlmost all oil and gas is found within the tiny spaces in sedimentary rocks, mainly sandstone and coarse-grained limestone. Bedrock limestone and sandstone, even though hard, also contain lots of pores that can contain water or oil or gas and other elements. Along with the gas and oil is a mixture of sand, silt & mud. This sludgy silt mud is rich in heavier metal elements ...

  • The largest source of anthropogenic mercury emissions

    The artisanal and small-scale gold mining (ASGM) is practiced in at least a dozen countries in Latin America. These industries are the largest source of anthropogenic mercury emissions which pollute the air, soil, and water and lead to severe problems with the human health. Therefore, mercury contamination has to be monitored and eliminated. We present you a whitepaper which outlines: ...

  • Sources of mercury in a contaminated stream—implications for the timescale of recovery

    Mercury contamination in East Fork Poplar Creek in Tennessee arises from dissolved mercury exiting a headwater industrial complex and residual mercury in the streambed and soil throughout the watershed downstream. The headwater inputs generate chronic base flow concentrations of total mercury of about 1,000 ng/L, but most of the annual export of mercury from the system appears to originate ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...

  • Seasonal and flow‐driven dynamics of particulate and dissolved mercury and methylmercury in a stream impacted by an industrial mercury source

    Sediments and floodplain soils in the East Fork Poplar Creek (EFPC) watershed in Oak Ridge, TN, are contaminated with high levels of mercury (Hg) from an industrial source at the headwaters. While baseflow conditions have been monitored, concentrations of Hg and methylmercury (MeHg) during high‐flow storm events, when the stream is more hydrologically connected to the floodplain, have yet to ...

  • Influence of carbon and lipid sources on variation of mercury and other trace elements in polar bears (Ursus maritimus)

    In the present study, the authors investigated the influence of carbon and lipid sources on regional differences in liver trace element (As, Cd, Cu, total Hg, Mn, Pb, Rb, Se, and Zn) concentrations measured in polar bears (Ursus maritimus) (n = 121) from 10 Alaskan, Canadian Arctic, and East Greenland subpopulations. Carbon and lipid sources were assessed using δ13C in muscle tissue and fatty ...

  • Environmental mercury in China: A review

    As a global pollutant, mercury can be transported over long distances and bioaccumulate. China is currently the greatest contributor to atmospheric Hg emissions and has the greatest intentional use of Hg. Mercuryin the Chinese environment is generally elevated, particularly in air and water bodies. Remote areas in China also show elevated Hg levels in air and water bodies compared with other ...

  • Modeling Mercury Fluxes and Concentrations in a Georgia Watershed Receiving Atmospheric Deposition Load from Direct and Indirect Sources

    Mercury (Hg) is considered a priority pollutant because of its toxicity and potential for strong bioaccumulation.There are many serious environmental and human health concerns associated with elevated levels of Hg linked to industrial ...

  • How to Monitor Mercury Emissions

    In recent years, mercury levels in the environment and in the food chain have risen substantially mainly due to human activities. As a long-range pollutant it can affect areas located thousands of kilometers away from its original source of emission. It’s no wonder then that the regulatory pressure to monitor mercury emissions grows stronger.  Before diving ...

  • Approaches to Reducing Mercury in North America

    This article provides a summary of the Environmental Protection Agencys role in reducing anthropogenic sources of mercury. These efforts are expected to substantially reduce both mercury releases and exposure. EPA is aware that mercury in the environment is complex and that it must work with programs in other federal agencies, state and local governments that address the mercury problem as well ...

  • Health implications of mercury exposure in children

    Mercury is a ubiquitous environmental toxin that can produce a wide range of health effects in humans. It is found in three chemical forms: organic, inorganic and elemental (mercury). The sources of exposure are also markedly different for the different forms of mercury. Diet, especially fish and other seafood, is the main source of exposure of the general public to organic mercury. Dental ...

  • Increase in mercury in Pacific yellowfin tuna

    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 dramatically since the Industrial Revolution. Evidence in ...

  • Will the new global mercury treaty be effective?

    Original story at MIT News MIT researcher Noelle Selin assesses the challenges of implementing the first global mercury treaty. After four years of negotiations, delegates from more than 140 countries met last January to finalize the first global treaty to mitigate and prevent mercury pollution, the ...

  • Human mercury exposure and effects in Europe

    The effects of human exposure to mercury (Hg) and its compounds in Europe have been the focus of numerous studies that differed in their design, including recruiting different population groups at different levels of exposure and by using different protocols and recruitment strategies. The objective of this work was to review current studies of Hg exposure in Europe, taking into account the ...

  • ZERO MERCURY - Key issues and policy recommendations for the EU Strategy on Mercury (December 2005)

    Mercury is a highly toxic metal, causing damage to the nervous system even at relatively low levels of exposure. It is particularly harmful to the development of unborn children. It collects in human and animal bodies and can be concentrated through the food chain, especially in certain types of fish. The Commission’s Directorate General for Health and Consumer Protection has recommended that ...

  • Assessing Consumer Awareness About Mercury in Fish

    The study discussed in this article was conducted to determine if a retail-based educational campaign would be an effective tool to inform consumers about mercury in fish. In 2005, the Rhode Island (RI) Department of Health, in conjunction with the RI Food Dealers Association, conducted surveys in eight supermarkets to assess consumers’ knowledge and awareness of mercury in fish. A presurvey was ...

  • Mercury – The Facts, Myths and Clean Up Tips!

    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 harmful effects of Mercury, many ...
