Carbon MonoxideCarbon Monoxide
•colorless, odorless
•produced when carbon does not burn in fossil fuels
•present in car exhaust
•deprives body of O2 causing headaches, fatigue, and impaired vision

Sulfur DioxideSulfur 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 DioxideNitrogen 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 MatterParticulate 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 OzoneGround Level Ozone
•at upper level, ozone shields Earth from sun’s harmful UV rays
•at ground level, ozone is harmful pollutants
•formed from car, power and chemical plant exhaust
•irritate respiratory system and asthma; reduces lung function by inflaming and damaging lining of lungs
