  • The safe extraction of valuable raw materials: robots automatically dismantle monitors containing mercury, while protecting workers’ health at the same time

    Machine handles up to 45 monitors per hour. According to initial projections, around three million LCD screens will be recycled in Germany in 2016. However, their backlighting system often contains mercury, which means they are classified as ‚hazardous waste‘ in accordance with the EWC, and as ‚Collection Group 3‘  in accordance with the Electrical and Electronic ...

  • 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 ...

  • 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, ...

  • Measuring unburned carbon in flyash with an automated, on-line monitor

    Increasingly stringent NOx regulations have required plant operators to modify traditional combustion processes. SOx regulations and deregulation have forced plant operators to diversify their coal sources. And new mercury control requirements have been instituted by the U.S. Environmental Protection Agency. These changes challenge plant operators who are trying to achieve the low carbon levels ...

  • Using the Bayesian Network Relative Risk Model risk assessment process to evaluate management alternatives for the South River and upper Shenandoah River, Virginia

    We have conducted a series of regional scale risk assessments using the Bayesian Network Relative Risk Model (BN‐RRM) to evaluate the efficacy of two remediation options in the reduction of risks to the South River and upper Shenandoah River study area. The two remediation options considered by South River managers were (1) the implementation of best management practices for agriculture ...
