  • 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 ...

  • EVALUATION OF STRATEGIES FOR MERCURY MACT COMPLIANCE

    On December 15, 2003, the United States Environmental Protection Agency (U.S. EPA) proposed a rule with two alternatives to permanently reduce mercury (Hg) emissions from power plants. Under one alternative, which is the focus of this paper, the utilities would install controls known as Maximum Achievable Control Technologies (MACT) under section 112 of the Clean Air Act (CAA). The proposed rule ...

  • 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 ...

  • Innovative emissions monitoring uptake soars

    Firms in the UK’s waste and power sectors are proactively seeking Best Available Techniques for emissions monitoring, according to Enviro Technology. Over recent months there has been a surge in demand for sophisticated equipment, such as monitors of total gaseous mercury. The air quality and emissions monitoring specialist believes that a combination of factors, such as the recast ...

  • Mercury Levels in Mink (Mustela vison) and River Otter (Lontra canadensis) from Northeastern North America

    Aquatic ecosystems have received mercury released from anthropogenic sources. The northeast region of North America is at especially high risk because of local and regional emission sources, prevailing wind patterns, and certain hydrological and biogeochemical features. Here we examine regional variation in total mercury (Hg) in brain, liver, and fur from otter and mink collected across New York, ...

  • Relative Accuracy Testing of an X-Ray Fluorescence-Based Mercury Monitor at Coal-Fired Boilers

    ABSTRACT The relative accuracy (RA) of a newly developed mercury continuous emissions monitor, based on X-ray fluorescence, was determined by comparing analysis results at coal-fired plants with two certified reference methods (American Society for Testing and Materials [ASTM] Method D6784-02 and U.S. Environment Protection Agency [EPA] Method 29). During the first determination, the ...

  • Analysis of low levels of metals in drinking water with a scanning array ICP emission spectrometer and ultrasonic nebulization

    Drinking water is an important factor in exposure to environmental contaminants and is used in preparing foods and beverages for human consumption. Therefore, great care is used to verify that it is free of or contains acceptable limits of toxic substances. With respect to heavy metals and other toxicologically relevant elements, atomic spectrometric techniques are frequently used to determine ...

  • On the suitability of Portable X-Ray Fluorescence Analyzers for rapid screening of toxic

    Abstract X-Ray Fluorescence spectrometry (XRF) has been routinely used for alloy testing, determination of Pb in paint, and determination of Cd in plastic. However, its use to screen for toxic elements in food and medicinal products has been surprisingly limited to date. While XRF is less sensitive than atomic spectrometry methods such as ICP-AES and ICP-MS, it offers a number of significant ...

  • Methylmercury in mosquitoes around a large coal‐fired power plant in Central Ohio

    Emissions from coal‐fired power plants are the major anthropogenic source of mercury (Hg) in the environment. Because emitted Hg can be deposited near the source, concerns arise about the effects of coal‐burning facilities on levels of toxic methylmercury (MeHg) in biota near such sources. We investigated the potential impact of a large Hg‐emitting (450 kg in 2005) coal‐fired power station in ...
