  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Mercury in the seafood and human exposure in coastal area of Guangdong Province, South China

    Consumption of fish and aquatic products is considered to be the main pathway of human exposure to methylmercury (MeHg). To assess human health risk through seafood consumption in a coastal area of Guangdong Province, South China, a total of 518 seafood samples (including fish, shrimp, crabs, and mollusks) were collected from 11 coastal cities for total mercury (THg) analysis. The THg ...

  • Patterns and Interpretation of Mercury Exposure in Freshwater Avian Communities in Northeastern North America

    A large data set of over 4,700 records of avian mercury (Hg) levels in northeastern North America was compiled and evaluated. As Hg emissions remain poorly regulated in the United States and Canada, atmospheric deposition patterns and associated ecological responses continue to elicit interest by landscape managers, conservation biologists, policy makers, and the general public. How avian Hg ...

  • 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 ...

  • Mercury Spill Control Procedures

    Mercury is a dangerous neurotoxin that can have damaging affects on both the central nervous system and renal system of humans. Exposure to mercury can cause serious developmental delays in children, and high level exposure is life threatening. When exposed to air, mercury vaporizes, readily becoming a dangerous aerosol that can be absorbed into the lungs and spread throughout the body. This is ...


  • Mercury Spill Control Procedures

    Mercury is a known neurotoxin that is extremely toxic even in small amounts. It directly affects the central nervous and renal systems, causing developmental delays, motor and brain problems like those associated with autism. Mercury"s hidden danger also lies in when at room temperature, when exposed it vaporizes readily. Once ...


  • Agreement on mercury finally here

    In Geneva 19 January 2013, due to successful interaction between science and policy making, governments within the UN agreed to a global, legally-binding treaty to prevent emissions and releases of mercury. Prof. Jozef Pacyna and his team at NILU - Norwegian Institute for Air Research, have played a major role in providing the UN policy makers with scientific justification for the treaty. 30 year ...

  • Influence of in ovo mercury exposure, lake acidity, and other factors on common loon egg and chick quality in Wisconsin

    We conducted a field study in Wisconsin to characterize in ovo mercury (Hg) exposure in common loons (Gavia immer). Total Hg mass fractions ranged from 0.17 to 1.23 µg/g wet weight (ww) in eggs collected from nests on lakes representing a wide range of pH (5.0 ‐ 8.1) and were modeled as a function of maternal loon Hg exposure and egg laying order. Blood total Hg mass fractions in a sample of ...

  • Projected mercury dietary exposure of three bird species nesting on a contaminated floodplain (South River, VA, USA)

    Dietary mercury exposure was modeled for Carolina wren (Thryothorus ludovicianus), Eastern song sparrow (Melospiza melodia) and Eastern screech owl (Otus asio) nesting on the contaminated South River floodplain (Virginia, USA). Parameterization of Monte Carlo models required formal expert elicitation to define bird body weight and feeding ecology characteristics because specific information was ...

  • 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 ...

  • Effect of mercury on the human health and environment: an overview

    This article aims to review and to demonstrate the effect of mercury on the human health and environment. Mercury is one of the 12 toxic pollutants identified by the US Environmental Protection Agency and can be toxic at low levels in the environment. Mercury can stay in the atmosphere for up to a year. When released to the air, mercury is transported and deposited globally. Mercury ultimately ...

  • L.A. mercury spill provides opportunity for education

    The uncertainty surrounding a mercury spill on a Los Angeles subway platform this past December was reported by many leading news organizations, including coverage by the Los Angeles Times, CNN and Fox News, among others. Many of these news stories focused on the slow response to the incident and the potential for this to have been associated with terrorism. While these are valid concerns that ...

  • Critical review of mercury SQVs for the protection of benthic invertebrates

    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 paired chemistry and benthic invertebrate effects ...
