  • Continuous Emissions Monitoring of Total Mercury

    Over the past decades, mercury (Hg, quicksilver) has gone from being a versatile commodity used in everything from thermometers to herbicides, to a partially banned substance, which name alone signals environmental issues and health concerns. Today, much use of mercury has been phased out in favour of more environmental- and health-friendly substances, and the remaining circulation of mercury is ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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, ...
