Presentation Transcript

  1. Air Pollution Instructor Özgür ZEYDAN (PhD.) Department of Environmental Engineering

  2. Air Pollution • Existence of air pollutants (gases and aerosols) in the atmosphere in a way that air becomes harmful to humans, animals, plants and materials.

  3. Air Pollutants Gases Aerosols • Sulfur oxides (SOx) • Nitrogen oxides (NOx) • Carbon monoxide (CO) • Volatile organic compounds – VOCs • Chlorofluorocarbons (CFCs) • Ground level ozone (O3) • Particulate matter • Toxic metals (lead, mercury …)

  4. USEPA – Criteria Pollutants

  5. Air Pollution

  6. Sources of Air Pollutants

  7. Primary and Secondary Pollutants

  8. Ground Level Ozone(Secondary Pollutant)

  9. Transport of Air Pollutants Air Pollution is a global environmental problem!

  10. Effects of Air Pollution • Human health effects • Effects on animals and plants • Effects on ecosystems • Acid rain • Stratospheric ozone depletion • Climate change • Effects on materials • Visibility reduction

  11. Health Effects of Air Pollution

  12. Acid Rain pH of natural rain water = 5.6 pH of acid rain < 5.6

  13. Effects of Acid Rain Acid rain, woods, Jizera Mountains, Czech Republic 

  14. Effect of Acid Rain on Sculptures

  15. Stratospheric Ozone Depletion

  16. Air Quality in Zonguldak (PM10 = 69 µg/m3) 18 March2014 - 08:40 (PM10 = 190 µg/m3) 17 March2014 - 17:44

  17. Air Quality in Paris August 17, 2012 - March 14, 2014

  18. Air Quality in Beijing, China August 2005

  19. Air Pollution in Hong Kong

  20. Particle Effects on Visibility June June

  21. Eyjafjallajökull Volcanic Eruption and Dust Clouds

  22. Air Quality Standards http://ec.europa.eu/environment/air/quality/standards.htm

  23. Air Pollution in Europe PM10 map (2012)

  24. Air Pollution in Europe SO2 map (2012)

  25. How to deal with air pollution? • Change your life style (Consume less! Pollute less!) • Conserve energy • Buy green (environmental friendly) products • Drive wisely or use public transport • Use clean energy sources • renewables are preferable instead of fossil fuels. • Good city planning • Separate residential and industrial zones • Reduce industrial emissions • Waste gas cleaning devices

  26. Environmental Engineers' Role Environmental Engineers study air pollution in several ways: • Measure current air quality • Design air pollution control equipments • Prepare emission inventories • Make air pollution modeling • Suggest clean air plans

  27. Not to remember Zonguldak with only Air Pollution Some beautiful pictures from Zonguldak

  28. Thanks for Listening Questions ???
