Document Summary
Both common and harmful [ex sulphur dioxide (so2 or sox or trs), nitrogen dioxide (no2 or nox), particulate matter (pm by particle size), volatile organic compound (voc or vox), carbon monoxide (co), ammonia (nh3), Tropospheric ozone (o3 ) - ex smog or bad air days for people with asthma]. Primary air pollutants from industrial sources combine chemically to form harmful compounds. Government regulations in developed countries have reduced smog. Photochemical smog (cid:523)aka (cid:498)brown(cid:499) air(cid:524) produced by a complex series of reactions. Light-driven reactions of primary pollutants and normal atmospheric compounds. Vehicle inspection programs: thermal inversions can worsen air pollution. Thermal inversion = layer of cool air trapped beneath a layer of warmer air. Denser, cooler air at the bottom of the inversion layer resists mixing: urban heat island effect - urban areas tend to be warmer than suburban, ontario aqi (air quality index) was replaced by the air quality health.
