Slide 9 - 5 Major Pollutants: 1..) Carbon Monoxide 2.) Sulfur Dioxide 3.) Nitrogen Dioxide 4.) Particulate Matter 5.) Ground Level Ozone
Slide 10 - Carbon 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
Slide 11 - 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
