Air pollution (2)

  1. 1. Air Pollution
  2. 2. Where does air pollution come from? Natural: forest fires, pollen, dust storm
  3. 3. Unnatural: man-made; coal, wood and other fuels used in cars, homes, and factories for energy
  4. 4. Major Pollutants 1.) Carbon Monoxide 2.) Sulfur Dioxide 3.) Nitrogen Dioxide 4.) Particulate Matter 5.) Ground Level Ozone
  5. 5. 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
  6. 6. 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
  7. 7. 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
  8. 8. 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
  9. 9. Ground 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
  10. 10. All these gases form SMOG which is a ….. Combination of gases with water vapor and dust Combination of words smoke and fog Forms when heat and sunlight react gases (photochemical smog) Occurs often with heavy traffic, high temperatures, and calm winds
  11. 11. The Effects The Greenhouse Effect
  12. 12. Global Warming
  13. 13. Thinning of Upper OZone Layer
  14. 14. Acid Rain
  15. 15. Indoor Air Pollution
  16. 16. What can we do to reduce air pollution? Ride your bike to school Tell your friends and family about pollution Make sure your parents get pollution checks on their cars Ride the school bus
  17. 17. Learn more about pollution and stay up to date Join a group to stop pollution Encourage your parents to carpool to work and school Switch off lights, fan, heat, etc. when you leave the room
  18. 18. Let’s take care of our pretty planet. Amy Caruana
