Air pollution hotspots are areas where air pollution emissions expose individuals to increased negative health effects. [282] They are particularly common in highly populated, urban areas, where there may be a combination of stationary sources (e.g. industrial facilities) and mobile sources (e.g. cars and trucks) of pollution.
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 ...
These sections require the EPA "(1) to list widespread air pollutants that reasonably may be expected to endanger public health or welfare; (2) to issue air quality criteria for them that assess the latest available scientific information on nature and effects of ambient exposure to them; (3) to set primary NAAQS to protect human health with ...
The EPA’s Clean Air Act identifies six common air pollutants which includes ozone and particulate matter. ... But ozone air pollution, where we can breathe it, causes “serious health problems ...
Clean Air Act standards. Under the Clean Air Act, the National Ambient Air Quality Standards (NAAQS) are developed by the Environmental Protection Agency (EPA) for six common air pollutants, also called "criteria pollutants": particulates; smog and ground-level ozone; carbon monoxide; sulfur oxides; nitrogen oxides; and lead.

Since the EPA first started regulating clean air in the 1970s, emissions of the most common air pollutants have dropped by almost 80%. But around Houston, there's still a long way to go. Each year ...
This is in part because pollution causes so many diseases that it is often difficult to draw a straight line between cause and effect. There are many types of pollution-related diseases, including those caused by air pollution, contaminated soil, water pollution and lacking water, sanitation and hygiene (WASH). Air pollution can be reduced.
