2. Indoor air quality - Wikipedia

   en.wikipedia.org/wiki/Indoor_air_quality

   Since indoor air pollutants can adversely affect human health, it is important to have real-time indoor air quality assessment/monitoring system that can help not only in the improvement of indoor air quality but also help in detection of leaks, spills in a work environment and boost energy efficiency of buildings by providing real-time ...

3. Air quality index - Wikipedia

   en.wikipedia.org/wiki/Air_quality_index

   A global air quality map. Real time monitoring data and forecasts of air quality that are color-coded in terms of the air quality index are available from EPA's AirNow web site. [51] Other organizations provide monitoring for members of sensitive groups such as asthmatics, children and adults over the age of 65. [52]

4. List of countries by air pollution - Wikipedia

   en.wikipedia.org/wiki/List_of_countries_by_air...

   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 caused an additional two million premature deaths in 2019. [1]

5. Air pollution measurement - Wikipedia

   en.wikipedia.org/wiki/Air_pollution_measurement

   Unlike low-cost monitors, which are carried from place to place, static monitors continuously sample and measure the air quality in a particular, urban location. Public places such as busy railroad stations sometimes have active air quality monitors permanently fixed alongside platforms to measure levels of nitrogen dioxide and other pollutants ...

6. Particulate pollution - Wikipedia

   en.wikipedia.org/wiki/Particulate_pollution

   In European countries, air quality at or above 10 micrograms per cubic meter of air (μg/m 3) for PM 2.5 increases the all-causes daily mortality rate by 0.2-0.6% and the cardiopulmonary mortality rate by 6-13%. [35] Worldwide, PM 10 concentrations of 70 μg/m 3 and PM 2.5 concentrations of 35 μg/m 3 have been shown to increase long-term ...

7. Beta attenuation monitoring - Wikipedia

   en.wikipedia.org/wiki/Beta_Attenuation_Monitoring

   Beta attenuation monitoring (BAM) is an air monitoring technique employing the absorption of beta radiation by solid particles extracted from air flow. The technique allows for the detection of PM 10 and PM 2.5 , which are monitored by most air pollution regulatory agencies.

8. NowCast (air quality index) - Wikipedia

   en.wikipedia.org/wiki/NowCast_(air_quality_index)

   PM 2.5 AQI of US monitors, calculated utilizing NowCast, courtesy US EPA PM2.5 AQI map, calculated utilizing NowCast, courtesy US EPA. The PM (particulate matter) NowCast is a weighted average of hourly air monitoring data used by the United States Environmental Protection Agency (USEPA) for real-time reporting of the Air Quality Index (AQI) for PM (PM 10 - particles less than 10 micrometers ...

9. Environmental monitoring - Wikipedia

   en.wikipedia.org/wiki/Environmental_monitoring

   Additionally, consideration of anemometer data in the area between sources and the monitor often provides insights on the source of the air contaminants recorded by an air pollution monitor. Air quality monitors are operated by citizens, [3] [4] [5] regulatory agencies, [6] [7] non-governmental organisations [8] and researchers [9] to ...
