this source. One reason for this is as a side-effect of measures that have been developed to reduce emissions of particulate matterfrom diesel vehicles by treating the exhaust using diesel particulate filters. These primary NO 2 emissions can lead to high concentrations of NO 2 at the roadside, especially where there are many diesel vehicles. NO

Diesel exhaust - Wikipedia

Diesel exhaust is the gaseous exhaust produced by a diesel type of internal combustion engine, plus any contained particulates.Its composition may vary with the fuel type or rate of consumption, or speed of engine operation (e.g., idling or at speed or under load), and whether the engine is in an on-road vehicle, farm vehicle, locomotive, marine vessel, or stationary generator or other ...

materials. The main sources of soil-related particles are roads, construction and agriculture. The main sources of combustion-related particles are diesel motor vehicles, managed burning, open burning, residential wood combustion, utility and commercial boilers. Figures 1-3 show that the PM-2.5 soil particle component is low (generally 5-15%).

main source of CO, NOx and PM 10 in 2000, with 76.9% of CO emissions, 52.2% of NOx emissions and 36.2% of PM10 emissions (figure 3). Road transport is the second source of NMVOC (28.6% of emissions), after the domestic, tertiary or indus-trial use of solvents (41.4%). Figure 3 provides an example of the sectorial

Particulate Matter (PM) Sources - Valley Air

Secondary PM sources directly emit air contaminants into the atmosphere that form or help form PM. Hence, these pollutants are considered precursors to PM formation. These secondary pollutants include SOx, NOx, VOCs, and ammonia. Control measures that reduce PM precursor emissions tend to have a beneficial impact on ambient PM levels.

Particulate matter (PM10 and PM2.5) | National Pollutant ...

Description. PM 10 is particulate matter 10 micrometers or less in diameter, PM 2.5 is particulate matter 2.5 micrometers or less in diameter. PM 2.5 is generally described as fine particles. By way of comparison, a human hair is about 100 micrometres, so roughly 40 fine particles could be placed on its width. PM 10 and PM 2.5 are not used for any application.

Particulate Matter (PM10) Trends | National Air Quality ...

National Trends in PM 10 Levels Using a nationwide network of monitoring sites, EPA has developed ambient air quality trends for particle pollution, also called Particulate Matter (PM). PM 10 describes inhalable particles, with diameters that are generally 10 micrometers and smaller.

Particulate Matters: Why monitor PM10 and PM2.5?

Particulate matter can come from both human and natural sources. Natural sources include sea salt, forest fires, pollen and mold. As they are natural occurrences, they are harder to control and are usually left unregulated. Human sources, however, can be regulated and understanding where PM comes from is very important.
