The document discusses various air pollutants including carbon monoxide, sulfur dioxide, nitrogen dioxide, particulate matter, ground level ozone, and smog. It describes what each pollutant is, how it is produced, its effects on health, and provides tips to reduce air pollution such as riding bikes, encouraging carpooling, and switching off lights when not in use.

Efforts by
anjali Any visible or invisible particle or gas found in the air that is not part of the original, normal composition. Natural: forest fires, pollen, dust storms
Unnatural: man-made; coal, wood and
other fuels used in cars, homes, and factories for energy AQI: Air Quality Index Indicates whether pollutant levels in air may cause health concerns. Ranges from 0 (least concern) to 500 (greatest concern) Carbon Monoxide colorless, odorless gas produced when carbon does not burn in fossil fuels present in car exhaust deprives body of O2 causing headaches, fatigue, and impaired vision Sulfur Dioxide produced when coal and fuel oil are burned present in power plant exhaust narrows the airway, causing wheezing and shortness of breath, especially in those with asthma Nitrogen Dioxide reddish, brown gas produced when nitric oxide combines with oxygen in the atmosphere present in car exhaust and power plants affects lungs and causes wheezing; increases chance of respiratory infection Particulate Matter particles of different sizes and structures that are released into the atmosphere present in many sources including fossil fuels, dust, smoke, fog, etc. can build up in respiratory system aggravates heart and lung disease; increases risk of respiratory infection Ground Level Ozone at upper level, ozone shields Earth from suns harmful UV rays at ground level, ozone is harmful pollutant formed from car, power and chemical plant exhaust irritate respiratory system and asthma; reduces lung function by inflaming and damaging lining of lungs Combination of gases with water vapor and dust Combination of words smoke and fog Forms when heat and sunlight react with gases (photochemical smog) Occurs often with heavy traffic, high temperatures, and calm winds 1st smog related deaths were in London in 1873; death toll 500 people; can you imagine how much worse the atmosphere is now?! Limits visibility Decreases UV radiation Yellow/black color over cities Causes respiratory problems and bronchial related deaths Ride your bike
