    New issues in air monitoring

    Sulfur Dioxide (SO2 ) EPA air quality standards have developed a new National Ambient Air Quality Standard (NAAQS) for Sulfur Dioxide concentration averaged over a one-hour period. Historically, attainment status has been assessed using existing monitors located across the nation. However, due to the large number of affected facilities and a lack of adequate spatial coverage of the existing ...

  • Individual power stations’ emissions can be identified from a distance

    Air pollutants and greenhouse gases (GHGs) from a coal-fired power station have been correctly identified 12 km away, researchers report in a new US study. Their monitoring method paves the way for a space-based satellite system which can check emissions reported by individual power stations against actual emissions. It is challenging to check the accuracy of emissions reported by nations under ...

  • ASTM D1607 - 91(2011) standard test method for nitrogen dioxide content of the atmosphere (griess-saltzman reaction)

    Nitrogen dioxide plays an important role in photochemical smog-forming reactions and, in sufficient concentrations, is deleterious to health, agriculture, materials, and visibility. In combustion processes, significant amounts of nitric oxide (NO) may be produced by combination of atmospheric nitrogen and oxygen; at ambient temperatures NO can be converted to NO2 by oxygen and other atmospheric ...

  • New insight into improving air quality measurements

    Researchers from the National Physical Laboratory (NPL) and King's College London have identified a mechanism which is responsible for under-reporting of peak nitrogen dioxide concentrations at some air quality monitoring stations, and the best ways to minimise this. Nitrogen dioxide (NO2) is an air pollutant formed when fuels are burned, for example, in car engines, domestic boilers and power ...
