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 ...
Ambient air quality criteria, or standards, are concentrations of pollutants in the air, and typically refer to outdoor air.The criteria are specified for a variety of reasons including for the protection of human health, buildings, crops, vegetation, ecosystems, as well as for planning and other purposes.
The CSAPR requires 23 United States states to reduce their annual emissions of sulfur dioxide (SO 2) and nitrogen oxides (NO x) to help downwind states attain the 24-hour National Ambient Air Quality Standards, and 25 states to reduce ozone season nitrogen oxide emissions to help downwind states attain the 8-hour NAAQS.
Some air pollution laws include specific air quality standards, such as the U.S. National Ambient Air Quality Standards and E.U. Air Quality Directive, [276] which specify maximum atmospheric concentrations for specific pollutants. Environmental agencies enact regulations which are intended to result in attainment of these target levels.
Section 202(a)(1) of the Clean Air Act requires the Administrator of the EPA to establish standards "applicable to the emission of any air pollutant from…new motor vehicles or new motor vehicle engines, which in [her] judgment cause, or contribute to, air pollution which may reasonably be anticipated to endanger public health or welfare" (emphasis added).

The most commonly used air quality index in the UK is the Daily Air Quality Index recommended by the Committee on the Medical Effects of Air Pollutants (COMEAP). [39] This index has ten points, which are further grouped into four bands: low, moderate, high and very high. Each of the bands comes with advice for at-risk groups and the general ...
Research shows that in-home environmental factors like noise, ambient temperature, light, and air quality can all impact sleep quality. These improvements can make all the difference: Install ...
Air pollution in Los Angeles has caused widespread concerns. In 2012, the Public Policy Institute of California (PPIC) Survey on Californians and the Environment showed that 45% of citizens in Los Angeles consider air pollution to be a "big problem", and 47% believe that the air quality of Los Angeles is worse than it was 10 years ago.
