  • 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 ...

  • 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 ...

  • Mapping Quality Assurance Requirements for Continuous Mercury Monitoring Systems

    The Clean Air Mercury Rule (CAMR) requires coal-fired electric power plants to install and operate mercury  continuous monitoring systems by December 31, 2008 such that they will have 12 months of “submittable” data by 1 January 2010. For all practical purposes, “submittable data” are “quality-assured data” that meet the extensive quality control requirements cited in the various regulations that ...

  • 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 ...

  • 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: ...

  • A dynamic model using monitoring data and watershed characteristics to project fish tissue mercury concentrations in stream systems

    A complex interplay of factors determines the degree of bioaccumulation of Hg in fish in any particular basin. Although certain watershed characteristics have been associated with higher or lower bioaccumulation rates, the relationships between these characteristics are poorly understood. To add to this understanding, a dynamic model was built to examine these relationships in stream systems. The ...

  • 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 ...

  • Air Rule for Cement Kilns Requires 92 Percent Cut in Mercury Emissions

    Portland cement kilns will be required to reduce emissions of mercury by 92 percent as part of an Environmental Protection Agency final rule announced Aug. 9 that imposes controls for several toxic pollutants. Although most of the emissions standards in the final rule are less stringent than what the agency had proposed in 2009, the cement industry said the cost to operate the required controls ...

  • Predictors of mercury spatial patterns in San Francisco Bay forage fish

    Pollution reduction efforts should be targeted towards those sources that result in the highest bioaccumulation. For mercury (Hg) in estuaries and other complex water bodies, carefully designed biosentinel monitoring programs can help identify predictors of bioaccumulation and inform management priorities for source reduction. We employed a probabilistic forage fish Hg survey with hypothesis ...

  • Mercury Removal from Nerve Gas Ton Container Rinse Waters

    IE was retained by a United States Army subcontractor to perform a process determination with analytical verification for the treatment of the rinse water from decontaminated nerve gas agents. The Pentagon Munitions Deconstruction Committee (PMDC) fully reviewed and approved the process developed. The wastewater was generated from the rinsing of 2,000-pound (ton) containers in a punch/drain/rinse ...

  • 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): ...

  • Dust monitoring

    Generally, two different approaches are used to measure the amount of dust deposited on a surface; Determination of the soiling of a surface, by a change in its properties; Determination of the quantity of dust deposited, by weight. WHAT IS DUST? Dust is a generic term used to describe fine particles that are suspended in the atmosphere. Dust comes from a wide variety of sources, including soil, ...

  • The determination of total mercury in whole blood using thermal decomposition and amalgamation coupled with atomic absorption

    Mercury has long been recognized as a serious global pollutant that has a significant impact upon our ecosystem. Unlike most other pollutants, it is highly mobile, nonbiodegradable, and bio-accumulative and as a result has to be closely monitored to ensure its harmful effects on local populations are minimized. Approximately 50 tons of mercury particulates are emitted into the atmosphere every ...
