    en.wikipedia.org/wiki/Volatile_organic_compound

    The VOC Solvents Emissions Directive was the main policy instrument for the reduction of industrial emissions of volatile organic compounds (VOCs) in the European Union. It covers a wide range of solvent-using activities, e.g. printing, surface cleaning, vehicle coating, dry cleaning and manufacture of footwear and pharmaceutical products.

    The Protocol to the 1979 Convention on Long-Range Transboundary Air Pollution Concerning the Control of Emissions of Volatile Organic Compounds or Their Transboundary Fluxes (known as the Volatile Organic Compounds Protocol or the VOC Protocol) is a protocol to the Convention on Long-Range Transboundary Air Pollution which aims to provide for the control and reduction of emissions of volatile ...

  4. Emission standard - Wikipedia

    en.wikipedia.org/wiki/Emission_standard

    Emission standards are the legal requirements governing air pollutants released into the atmosphere. Emission standards set quantitative limits on the permissible amount of specific air pollutants that may be released from specific sources over specific timeframes. They are generally designed to achieve air quality standards and to protect ...

    en.wikipedia.org/wiki/Indoor_air_quality

    Testing emissions from building materials used indoors has become increasingly common for floor coverings, paints, and many other important indoor building materials and finishes. [49] Indoor materials such as gypsum boards or carpet act as VOC 'sinks', by trapping VOC vapors for extended periods of time, and releasing them by outgassing.

    If a gaseous emission sample is analyzed and found to contain water vapor and a pollutant concentration of say 40 ppmv, then 40 ppmv should be designated as the "wet basis" pollutant concentration. The following equation can be used to correct the measured "wet basis" concentration to a " dry basis " concentration: [ 3 ]

  7. Vehicle emissions control - Wikipedia

    en.wikipedia.org/wiki/Vehicle_emissions_control

    Emission test results from individual vehicles are in many cases compiled to evaluate the emissions performance of various classes of vehicles, the efficacy of the testing program and of various other emission-related regulations (such as changes to fuel formulations) and to model the effects of auto emissions on public health and the environment.

  8. Emission control area - Wikipedia

    en.wikipedia.org/wiki/Emission_Control_Area

    Emission control areas (ECAs), or sulfur emission control areas (SECAs), are sea areas in which stricter controls were established to minimize airborne emissions from ships as defined by Annex VI [1] of the 1997 MARPOL Protocol. The emissions specifically include SOx, NOx, ODSs and VOCs [2] and the regulations came into effect in May 2005.

    Global NMVOC emissions from anthropogenic sources have been increasing over time, with the emissions amount rising from 119,000kt to 169,000kt between 1970 and 2010. [4] Regionally, trends vary, with America and Europe reducing their emissions in the same time period, while Africa and Asia increased their NMVOC emissions in this period. [ 4 ]
