  • 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 ...

  • Climate change and watershed mercury export: A multiple projection and model analysis

    Future shifts in climatic conditions may impact watershed mercury (Hg) dynamics and transport. We apply an ensemble of watershed models to simulate and evaluate the responses of hydrological and total Hg (HgT) fluxes from the landscape to the watershed outlet and in‐stream HgT concentrations to two contrasting climate change projections for a watershed in the southeastern Coastal Plain of the ...

  • Mercury and other Contaminants in Common Loons Breeding in Atlantic Canada

    Common loons (Gavia immer) were studied to assess the biomagnification of persistent contaminants in lake ecosystems in Atlantic Canada. Forty-two breeding adults and 20 juvenile loons were captured in August, 1995–1997 on lakes in four areas of southern New Brunswick (Lepreau and Fundy National Park) and Nova Scotia (Halifax and Kejimkujik National Park). Blood samples were collected for ...

  • Aqueous and vapor phase mercury sorption by inorganic oxide materials functionalized with thiols and poly-thiols

    The objective of the study is the development of sorbents where the sorption sites are highly accessible for the capture of mercury from aqueous and vapor streams. Only a small fraction of the equilibrium capacity is utilized for a sorbent in applications involving short residence times (e.g., vapor phase capture of mercury from coal-fired power plant flue gases). So, dynamic capacity rather than ...

  • The identification and testing of a method for mercury-free gold processing for artisanal and small-scale gold miners in Ghana

    A study of the ASM sector of Ghana established the practices and attitudes of gold miners and proposed an alternative to mercury amalgamation. The study showed that miners were aware of health hazards associated with mercury but continued to use it because they knew of no credible alternative. It was realised that any process to replace amalgamation must be very efficient to capture gold around ...

  • 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 ...

  • High levels of maternally transferred mercury do not affect reproductive output or embryonic survival of northern water snakes (Nerodia sipedon)

    Maternal transfer is an important exposure pathway for contaminants because it can directly influence offspring development. Few studies have examined maternal transfer of contaminants, such as mercury (Hg), in snakes, despite their abundance and high trophic position in many ecosystems where Hg is prevalent. The objectives of the present study were to determine if Hg is maternally transferred ...

  • Developing a Cyberinfrastructure for Integrated Assessments of Environmental Contaminants

    The objective of this study was to design and implement prototype software for capturing field data and automating the process for reporting and analyzing the distribution of mercury. The four phase process used to design, develop, deploy and evaluate the prototype software is described. Two different development strategies were used: (1) design of a mobile data collection application intended to ...

  • Trace elements - controlling emissions from coal combustion

    International and national legislation is increasingly being applied to trace element emissions. Although emissions have decreased for a variety of reasons in many developed countries, continued use of coal and more successful control strategies in other sectors mean that coal combustion is still a relatively important source of some trace elements, especially mercury. Existing pollution control ...

  • How the federal utility MACT rule may affect US businesses

    The final standards for hazardous air pollutant (HAP) emissions from electric generating units (EGUs), one of the last industries to be regulated by MACT, was just published in the Federal Register on February 16 and officially goes into effect on April 16, 2012. The rule (“Utility MACT”) had been long awaited; the USEPA began developing it 11 years ago. According to federal NESHAP, ...


  • WESPS continue to deliver

    Compliance with the increasingly stringent air pollution regulations of recent years is not the only reason forwardthinking industry leaders are adopting more sophisticated gas cleaning and air pollution control strategies. The desire to achieve higher performance efficiencies, control costs in a competitive marketplace, and stay ahead of the regulatory compliance curve is another driver of ...

  • Report: California’s Reliance on brackish water desalination to increase

    Years of drought in California may result in the state becoming more reliant on brackish water desalination, according to the Pacific Institute. In “The Cost of Alternative Water Supply and Efficiency Options in California,” the Oakland-based nonprofit research institute looks at the costs of potential water supply sources and other economic factors. The institute states: ...
