  • Arctic - A sink for atmospheric mercury

    Recently, a new phenomenon has been shown which implies that the deposition flux of mercury in the Arctic is considerable at a time of the year when biota are preparing for peak summertime activity. During spring 2000, frequent episodic depletions in mercury vapour (TGM) concentrations were observed at NILUs research station at Svalbard ...

  • 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 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 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 ...

  • 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 ...

  • 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 ...

    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 ...

  • 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 ...


  • 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 ...

  • 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 ...


  • 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 ...

  • Inorganic mercury accumulation in rice (Oryza sativa L.)

    To investigate the source and process of inorganic mercury (IHg) accumulation in rice, we monitored the concentrations of IHg in tissues of rice plants (Oryza sativa L.) from four experimental plantation plots. Biweekly during the rice‐growing season, tissues of rice plants, corresponding soil, precipitation, and irrigation water samples were collected. The sampling data support the following: ...

  • 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 ...

    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 ...
