  1. Smog/Ground level ozone By: Emily Khalili and Audrey Lopez

  2. What is ground level ozone (Smog)? • Definition: mixture of harmful air pollutants (fog, smoke etc.) in atmosphere • Ozone is the chemical of O3 • Layer of smog in atmosphere- troposphere

  3. What is ground level ozone (Smog)? • How is it created? • Chemical reaction of oxides of nitrogen (NO3) and volatile organic compounds (VOC) • Sunlight stimulates the chemical reaction • Chemical reaction • NO3 + VOC + Sunlight = 03

  4. Causes of Smog/Ground Level Ozone • Lots of smog b/c of the abundant emission of NO3 and VOC • What are sources of NO3 and VOC? • Gasoline-powered vehicles (cars) • Lawn equipment • Industrial facilities • Burning of fossil fuels

  5. Causes of Smog/Ground Level Ozone • More common in urban cities • Why? Most cars and industrial facilities are located there • High ozone levels usually during the summer • Why? More sunlight

  6. Health Effects of Smog/Ground level ozone • Children at high risk b/c lungs are still developing • Smog targets the lungs • Breathing problems b/c of smog • Chest pain/coughing • Bronchitis • Asthma • Lungs vulnerable to infections • Permanent scaring of lung tissue

  7. solutions • Using a cleaner commute helps with lowering the ozone level such as: • Carpooling • Riding a bike • Conserving electricity • Mulching/composting leaves or yard waste

  8. outlook • The Clean Air Interstate Rule: • A rule which is only effective in 27 states on the East • Regulates air emission from stationary and mobile sources. • National Ambient Air Quality Standards • Ozone- 0.075 parts per million (volume) • 8 hr concentration averaged over 3 years • Smog checks • Required check of amount of gas emitted from cars and other vehicles

  9. contacts • If very concerned about Ozone and the harm that it includes, you can contact: • United States E.P.A (Enviromental Protection Agency) • http://www.airnow.gov/ • Gives forecast of air quality conditions in specific areas
