  • 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 ...

  • Long-term Atmospheric Mercury Wet Deposition at Underhill, Vermont

    Section 112(m) of the 1990 Clean Air Act Amendments, referred to as the Great Waters Program, mandated an assessment of atmospheric deposition of hazardous air pollutants (HAPs) to Lake Champlain. Mercury (Hg) was listed as a priority HAP and has continued to be a high priority for a number of national and international programs. An assessment of the magnitude and seasonal variation of ...

  • Atmospheric Mercury Concentrations from Several Observatory Sites in the Northern Hemisphere

    In an effort to investigate both large-scale (spatial) and short/long-term (temporal) distribution characteristics of atmospheric mercury, we have combined and analyzed the Hg concentration data sets collected continuously by four different scientific groups for the areas and periods covering (1) America (three sites near the Canadian Great Lakes (CGL): 1997–2000), (2) Asia (Seoul, Korea (SEL): ...

  • Mercury stabilization takes the sting out of mercury

    In elementary form, mercury is a danger to humans and the environment. But chemically bound to sulfur it loses its toxicity and can be disposed safely. The process which transforms the highly toxic metal into an unproblematic red powder is called mercury stabilization. As a specialist for cleaning mercury contaminated soil and waste by vacuum distillation econ also offers a process for mercury ...

  • Mercury Control Demonstrations

    C1.1 | Halogens and Sulfur in Coals and their Influence on Co-benefit Mercury Capture Bernhard Vosteen | President, Vosteen Consulting Gmbh Not only the range of the coal mercury content itself, but also the range of the native halogen and sulfur contents in coal are of great influence on co-benefit mercury capture, wet and dry. The ...

  • Designing a relational database for tracking and analysis of atmospheric deposition of mercury and trace metals in the Pensacola (Florida) Bay Watershed

    The need to track and analyse the atmospheric deposition of mercury and trace metals in the Pensacola (Florida) Bay Watershed in recent years has resulted in the need for a data management system that will allow data to be efficiently stored, checked for errors, manipulated, retrieved for analysis and shared within the research community. In this paper, we describe a relational database that was ...

  • 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 investigate mercury in the oceans?

    Mercury is a highly toxic metal that affects the environment and can endanger people's health, as a powerful neurotoxin. The combustion of coal, waste and fuel are releasing hundreds of tons of heavy metal into the atmosphere annually, and its sediment enters to soil and water. Mercury measurements are part of the EU project "Global Mercury Observation System". The long-term goal of this ...

  • 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 ...

  • 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 ...

  • Global change and mercury cycling: Challenges for implementing a global mercury treaty

    The Minamata Convention aims to protect human health and the environment from anthropogenic emissions and releases of mercury. The provisions of the Minamata Convention are examined to assess their influence on global biogeochemical cycling of mercury. Though the Convention's scope covers all major categories of atmospheric emissions, the degree to which it will affect future emissions ...

  • 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 ...

  • 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 ...

  • Response of fish tissue mercury in a freshwater lake to local, regional, and global changes in mercury emissions

    A suite of mechanistic atmospheric and mercury cycling/bioaccumulation models is applied to simulate atmospheric mercury deposition and mercury concentrations in the water column and fish in a mercury‐impaired freshwater lake located in the northeastern United States that receives its mercury loading primarily through deposition. Two future‐year scenarios evaluate the long‐term response of ...

  • 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 ...

  • Soil CEC and Selectivity Sequence for Mercury (II) Ion

    Abstract Mercury is one of the most hazardous air and water pollutants. Since the issuance of the Clean Air Mercury Rule for coal-fired electric boiler utilities in March 2005, numerous scientific researches have focused on the fate and transport of mercury in both atmosphere and aqueous environment. The issue of aqueous mercury transport as the major mercury transport mechanism becomes more and ...

  • Pre‐anthropocene mercury residues in North American freshwater fish

    Mercury has been entering the environment from both natural and anthropogenic sources for millennia, and humans have been influencing its environmental transport and fate from well before the Industrial Revolution. Exposure to mercury (as neurotoxic monomethylmercury (MeHg)) occurs primarily through consumption of finfish, shellfish, and marine mammals, and regulatory limits for MeHg ...

  • Deconstruction of Historic Mercury Accumulation in Lake Sediments, Northeastern United States

    Total atmospheric contribution of mercury (HgT) to lake sediment was estimated using 210Pb-dated sediment cores. Algorithms based on estimates of lake and watershed processes were applied to more accurately assess anthropogenic contributions of Hg to the environment and HgT. Factors addressed include: lake-specific background accumulation rates of Hg (HgB), variability of sediment accumulation ...
