Air is monitored by:
* Processing a lot of air though a filter or absorption systems and then seeing what was caught. this works for gaseous pollutants (SOx, NOx, hydrocarbons) and particulates. * Exposing reactive chemicals to ambient air for extended periods of time to see what was in the ambient air. (Sulfur candles)
* Passing light (lasers) through the air and recording the wavelengths that were absorbed or reflected from the air pollutants. * Monitoring the percent of light obstructed by the pollutant in the air (opacity) * Organoleptic monitoring (a fancy way of saying you sniff and look at the air with your senses) * Examining the impact of the air pollutant on plants (Phytotoxicological examonation) either in labs or in the field (Pollutants such as SOx and ethylene) * Monitoring epidemiological studies to determine long term impacts on human health
As everyone can see,the air pollution index is use by thegovernment to measure the air quality index and to detect anypollutants in our country¶s air.This is to ensure the air is cleanand safe for us to inhale.Besides that,an early warning can begiven to us if the air pollution is to high for us to get out of our homes. This warning is given based upon readings andinterpretations of the air pollution index
air pollution travels in the air
there's air pollution everywhere no matter where you go there's air pollution.
