Air pollution can affect nearly every organ and system of the body, negatively affecting nature and humans alike. Air pollution is a particularly big problem in emerging and developing countries, where global environmental standards often cannot be met. The data in this list refers only to outdoor air quality and not indoor air quality, which ...
Air pollution can occur naturally or be caused by human activities. [4] Air pollution causes around 7 or 8 million deaths each year. [5] [6] It is a significant risk factor for a number of pollution-related diseases, including heart disease, stroke, chronic obstructive pulmonary disease (COPD), asthma and lung cancer.

[2] A contaminant may even be more abstract, as in the case of an unwanted energy source that may interfere with a process. [2]
The air monitoring site located in Labrador City is an industrial station for which Environment Canada has added an ozone monitor to predict an air quality health index for the area. Data from the NAPS Program are included in the Canada-wide Air Quality Database and are published in annual air quality data summary reports.
Nonpoint source air pollution affects air quality, from sources such as smokestacks or car tailpipes. Although these pollutants have originated from a point source, the long-range transport ability and multiple sources of the pollutant make it a nonpoint source of pollution; if the discharges were to occur to a body of water or into the ...
