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.
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 ...
Subchapter C - Air Programs (Parts 50 - 97) (Clean Air Act) [2] National Ambient Air Quality Standards (NAAQS) Criteria air contaminants; Requirements for Preparation, Adoption and Submittal of Implementation Plans; Approval and Promulgation of Implementation Plans; Ambient Air Monitoring Reference and Equivalent Methods; Prior Notice of ...
Air quality monitors are operated by citizens, [3] [4] [5] regulatory agencies, [6] [7] non-governmental organisations [8] and researchers [9] to investigate air quality and the effects of air pollution. Interpretation of ambient air monitoring data often involves a consideration of the spatial and temporal representativeness [10] of the data ...
The National Ambient Air Quality Standards (NAAQS) are set by the Environmental Protection Agency (EPA) to regulate pollutants in the air. The enforcement of these standards is designed to prevent further degradation of air quality. States may set their own ambient standards, so long as they are lower than the national standard. [21]
The European Environment Agency collects its air quality data from 3,500 monitoring stations across the continent. [24] The measurements made by sensors like these, which are much more accurate, are also near real-time and are used to generate air quality indexes (AQIs). Between the two extremes of large-scale static and small-scale wearable ...
The reports provide guidelines intending to give guidelines to reduce the health effects of air pollution. [2] The guidelines stipulate that PM 2.5 should not exceed 5 μg/m 3 annual mean, or 15 μg/m 3 24-hour mean; and that PM 10 should not exceed 15 μg/m 3 annual mean, or 45 μg/m 3 24-hour mean. [2]
Initial guidelines for a DfE approach were written in 1990 by East Meets West, a New York-based non-governmental organization founded by Anneke van Waesberghe. It became a global movement targeting design initiatives and incorporating environmental motives to improve product design in order to minimize health and environmental impacts by ...
