<onlyinclude>'''Primary pollutants''' are any type of [[pollutant]] emitted directly into the [[environment]].

The effects of primary pollutants are of concern as they can be harmful to humans, animals and plants.<ref>BC Air Quality. (Accessed July 23, 2015). ''Pollutants: An Introduction'' [Online], Available: http://www.bcairquality.ca/101/pollutants-intro.html</ref> Their contribution to the formation of secondary pollutants is also concerning, as this is what causes harmful [[ozone|ground level ozone]] to form, along with different [[smog]]s, especially in densely populated cities such as Los Angeles.

The emission of primary pollutants has decreased considerably in the past years, due to improved regulations, technology and economic changes.<Ref>NASA. 2014. ''New NASA images highlight U.S. Air Quality Improvement'' [Online], Available: https://www.nasa.gov/content/goddard/new-nasa-images-highlight-us-air-quality-improvement/#.VbEhrrNVikp</ref> [https://www.nasa.gov/content/goddard/new-nasa-images-highlight-us-air-quality-improvement/#.VbEhrrNVikp Click here] to see some cool images from NASA on how air pollution has decreased in the past years.

Types of primary pollutants include:<Ref>LSC Atmospheric Sciences. (Accessed July 23, 2015). ''Primary Pollutants'' [Online], Available: http://apollo.lsc.vsc.edu/classes/met130/notes/chapter18/primary.html</ref>

*[[NOx|Nitrogen oxides (NOx)]]
*[[Carbon monoxide]] (CO)
*[[Volatile organic compound]]s (VOCs)
*[[SOx|Sulfur oxides (SOx)]]
*[[Particulate matter]] (PM)
*[[Mercury (pollutant)|Mercury]]
*and more

Note*: Certain pollutants may be both primary ''and'' secondary pollutants. NOx for example is emitted from vehicles and power plants, yet it can also form in the atmosphere from other [[chemical]]s.

==Data Visualization (Pollutants in Canada)==

[[Transportation]] is the leading contributor of many primary pollutants due to burning of [[gasoline]] and [[diesel]], which produce many of these harmful pollutants. The industrial sector is also a major contributor. The data visualization depicts the emissions of various primary pollutants by source and province. The drop down tabs at the top may be selected to switch between pollutants, along with delving into specific sectors to see exactly where these emissions come from.

'''For example:'''

Select "Nitrogen oxides" (preset) and "Industrial" to see how Alberta's [[upstream oil and gas industry]] contributes to NOx emissions.

or

Select "Lead" and "Industrial" to see how Quebec's smelting industry contributes to these emissions.
