    Method X is an instrumental analyzer procedure for the determination of multiple metals using x-ray fluorescence as an analytical technique. Method X specifies the criteria for accuracy stability and precision that must be met by an x-ray fluorescence based instrument analyzer. Method X also describes the emission test procedures associated with an x-ray fluorescence based metals measurement ...

  • Dry regenerable sorbents for the separation and capture of CO2 from large point sources

    The combustion of fossil fuels generates large quantities of carbon dioxide (CO2), a greenhouse gas most likely to influence global warming and climate change. Large stationary sources that include coal-based electric generating stations are plausible targets for the removal of CO2. Chemical absorption of CO2 is viewed as one option that could be applicable ...

  • Heavy Metals Water Testing Powered by DNA

    Water pollution is a worldwide problem affecting developing and developed countries alike. Heavy metal contaminants are one prevalent type of water pollutant. They are persistent in the environment once d is charged and removal from source waters is necessary to ensure a clean drinking water supply. The problem of heavy metal pollution arises from several sources. Heavy metals such as uranium can ...

  • Methodology of model testing and application to dispersion simulation above complex terrain

    This paper concerns an integrated model testing exercise focussed on the use of model performance statistical indices. SAFE_AIR is a multisource model mainly designed to describe dispersion of airborne pollutants from point sources at local-to-regional scales over complex terrain in non-stationary meteorological and emission conditions. It was applied in the region of Ilo, Peru, a complex coastal ...

  • Case study - Wall leakage testing in the lab with acoustic camera

    Problem Facade insulation testing is usually performed by using a loudspeaker in the sending room, and record the sound pressure level (SPL) with microphones in both the sending and receiving room. The difference in SPL adjusted for the size of the dividing wall element will then give an estimate of the sound reduction quality of that element. However these measurements will not say ...

  • Development and first tests of a data assimilation algorithm in a Lagrangian puff atmospheric dispersion model

    The development of a Data Assimilation algorithm based on variational approach that allows estimation of source emission rate in Lagrangian particle/puff Atmospheric Dispersion Models for non-stationary (wind and source) conditions is presented. The one-dimensional tests including constant and variable in time source emission rate and wind velocity showed that methodology can be extended to take ...

  • How to Select Permit Conditions That Ensure Maximum Operational Flexibility: A Case Study at a Cardboard Manufacturing Site

    The identification and acquisition of flexible permit conditions has been essential to the successful operation and compliance status of a cardboard manufacturing site in Los Angeles. In 1999, the owner was cited for exceeding the volatile organic compound (VOC) emission limits on two stationary sources by the California Air Quality Management District (CAQMD). A notice of violation (NOV) was ...

  • Capture of carbon dioxide from flue gas using solid regenerable sorbents

    Carbon dioxide emissions from the combustion of fossil fuels are a significant factor in global climate change. Large stationary sources such as coal-fired electric generating plants are likely to be the most cost-effective targets for carbon dioxide capture. At present, liquid amine-based scrubbing systems are the only processes available for this application. Processes based on regenerable ...

  • New boiler MACT and affiliated rules proposed

    EPA proposed three related rules (with final rules expected by December 16, 2010), intended to reduce the emission of hazardous air pollutants (HAPs) from industrial, commercial, and institutional boilers and process heaters as well as commercial and industrial solid waste incinerators. Simultaneously, it also proposed a definition of solid waste that could potentially affect some units currently ...

  • Rapid blending of nutraceuticals in a restricted space

    Although vitamins and minerals have long been a mainstay in health maintenance, a new category of health maintenance products has created an entirely new market over the last two decades. The term "nutraceutical" was first defined in 1989 by Stephen DeFelice, M.D. as "... food, or parts of a food, that provide medical or health benefits, including the prevention and treatment of disease." Since ...

  • Federal GHG reporting rule proposed

    On March 10, 2009, EPA proposed federal greenhouse gas (GHG) reporting requirements as authorized by the FY08 Omnibus Appropriations Act (H.R. 2794; Public Law 110-161), signed Dec. 26, 2007. EPA developed the rule to collect comprehensive GHG emissions data that can be used to inform EPA and government agencies for future policy decisions. EPA’s rulemaking approach used screening criteria ...

  • The invisible fine dust

    Air is lifeblood. Daily we inhale approximately 15.000 liter. Still, the air contains invisible pollutants, which vary in its composition and concentration depending on the location. Especially the respirable particles with a diameter of less than 2.5 µm (PM 2.5) were considered to be particularly dangerous. According to a current study conducted by the Max Planck Society, ...

  • How has MCERTS impacted CEMS?

    Industrial process operators that produce gas emissions to atmosphere are regulated by the Environment Agency.
