  • High NOx Emissions from Diesel Cars

    It is time to sell your diesel car. In a few years you will not be able to use it in a city. The real drive emissions measurements from passenger cars are giving astonishing results. A new diesel car has 10 times higher NOx emissions compared to a petrol car. Even worse, the NOx emitted from the diesel car is up to 50% emitted as NO2. The NOx emitted from a petrol car is only a few % emitted as ...

  • AQMesh scaled against reference demonstrates accuracy in new location – Barcelona, Spain

    Through partnership with IDAEA-CSIC two AQMesh pods were co-located with a reference station and scaled locally in Barcelona (ref. Advanced user mode), providing R2 of 0.97 for NO and 0.89 for NO2. One pod was then moved to a second reference point within the city to establish repeatability of results using the scaling factors derived from the first reference. This resulted in a correlation of ...

  • Environnement S.A announces the AS32M: the unique analyser allowing quick and direct measurement of NO2

    The European Directive 2008/50/EC requires the measurement of nitrogen dioxide (NO2) at minima in all agglomerations of more than 100 000 inhabitants. Currently, some of these sites do not meet the limit values and quality objectives set, particularly on sites located in the vicinity of roads (traffic sites), directly impacted by vehicle emissions. The uncertainties related to measurement ...

  • Atmospheric particulate matter in Germany `excessive` in 2007, says federal environment agency

    The German Federal Environment Agency’s preliminary evaluation of 415 measuring stations demonstrates that favourable atmospheric conditions in 2007 were a relevant factor that account for lower levels of particulate pollution than in previous years. Yet there is absolutely no reason to sound the all-clear, for 2007 also had incidences of particulate matter concentrations above the established ...

  • E Instruments Announces F5000 Automotive Exhaust Analyzer Can Now Monitor for NO2

    If you spend your days analyzing and monitoring emissions, then you’re about to be given a real treat. We here at E Instruments—an American-based designer and manufacturer of high-quality automotive exhaust analyzers—are pleased to announce that our F5000 Automotive Exhaust Analyzer can now monitor for NO2. Why We Made This Upgrade As many diesel vehicles continue to emit ...

  • Air pollution from road traffic can raise blood pressure

    High blood pressure is linked to long-term exposure to traffic-related air pollution, new research suggests. After accounting for lifestyle factors, socioeconomic status and pre-existing health conditions, the researchers found that a rise in traffic emissions of nitrogen dioxide corresponded to a rise in blood pressure of exposed individuals. Long-term exposure to air pollution has previously ...

  • New Product Alert – VICONOX NO2, NO, CO and Visibility Monitor

    More and more modern vehicles emit less and less CO so there is a growing international requirement to measure the level of both CO and NO/NO2 in road tunnels. The VICONOX provides an elegant solution to these requirements by measuring NO2, NO, CO, visibility and temperature within a single sensor. Designed specifically for use in tunnels, the VICONOX tunnel monitor uses a combination of ...

  • 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. ...
