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 ...
Air pollutants can also cause other types of cancer. Another study found that the hazardous air pollutant (HAP) can cause cervical cancer and the upper aero-digestive tract cancer. [49] The cancer caused by air pollution is not equally distributed in the United States. Cancer incidence and death rates are higher in African Americans than other ...

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 ...
