  To develop an emission inventory for an area, one must (1) list the types of sources for the area, such as cupolas, automobiles, and home fireplaces (see Figure ); (2) determine the type of air pollutant emission from each of the listed sources, such as particulates and SO 2; (3) examine the literature to find valid emission factors for.

NEMS National Energy Modeling System. Particulates – also known as atmospheric aerosol particles, atmospheric particulate matter, particulate matter (PM), or suspended particulate matter (SPM) – are microscopic particles of solid or liquid matter suspended in the term aerosol commonly refers to the particulate/air mixture, as opposed to the particulate matter alone. Sources of particulate matter can be . Natural sources. Natural sources of PM 10 and PM include bushfires, dust storms, pollens and sea spray. Transport sources. Vehicles will generate particulates either from direct emissions from the burning of fuels (especially diesel powered vehicles) or from wear of tyres or vehicle-generated air turbulence on roadways.

Particles originate from a variety of stationary and mobile sources and may be directly emitted (primary emissions) or formed in the atmosphere (secondary emissions) by transformation of gaseous emissions. Significant Primary and Secondary Particulate Matter Sources. Primary PM sources are derived from both human and natural activities. Particulate matter (PM), particulates, or particle pollution are general terms for solid or liquid particles found in the atmosphere; these particles may be of varying sizes and chemical composition. The smaller the particles, the more easily and deeply they can enter our lungs and create health problems. The National Particulates Inventory is a air emissions inventory for the U.S. (excluding Alaska and Hawaii), Canada and Mexico. The inventory includes the following pollutants: PM PM Sulfur dioxide (S02) Oxides of nitrogen (NOE) Ammonia (NH3) Volatile organic compounds (VOC) Secondary organic aerosols (SOA) Primary PM emissions include PM .

The National Pollutant Inventory (NPI) is a database of Australian pollution emissions managed by the Australian Commonwealth, State and Territory Governments. A condensed version of the information collected is available to the public via the NPI website references arranged by seven primary categories covering the literature dealing with air pollution in Canada. Includes author, subject and geographical indexes Standard reference method for the measurement of nitrogen dioxide in the atmosphere (chemiluminescence method) by Canada (Book). Figure UK emissions of PM Figure UK emissions of PM 1. Figure UK emissions of PM Accuracy of Particulate Matter Estimates. Although the primary emissions inventory for PM 10 is continuously being improved, the uncertainties in the emission estimates must still be considered high. These uncertainties stem from uncertainties in the emission factors . Particulate matter may be present in exhaust fumes emitted into the atmosphere by cars and trucks, especially diesel-powered ones. Particulate matter can also be released into the environment from wear and tear on tyres, or the wind currents created by vehicles on roads. Trucks carrying sand or other similar loads can also spread particulate.
