  • ASTM D3608 - 95(2011) standard test method for nitrogen oxides (combined) content in the atmosphere by the griess-saltzman reaction

    Both NO2 and NO play an important role in photochemical-smog-forming reactions. In sufficient concentrations NO2 is deleterious to health, agriculture, materials, and visibility. In combustion processes, significant amounts of 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 oxidants. ...

  • Evaluating the impact of air quality measures is essential

    Recent research has investigated the effectiveness of air quality management at the regional level in Italy and found that some of the most commonly adopted measures do not always produce the highest emissions reductions. Italian air quality legislation was reformed in 1999 in order to comply with the 1996 European Air Quality Framework Directive1. At the time, the 20 Italian administrative ...

  • Europe to require “Real World” emission tests in 2017

    European auto manufacturers have made considerable progress in reducing nitrogen oxide (NOx) emissions, but experts at Emissions Analytics note that challenges remain. The European Commission will require “real world” vehicle emission tests beginning in 2017. Emissions approval for passenger cars in Europe will then include mandatory on-the-road tests using a portable emissions ...

  • 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 ...
