  1. With increasing breathing problems, this is an important section. Asthma cases have doubled since 1990. Environmental Pollution is part of the problem. Air Quality

  2. How Does Air Quality Concern You? • Human Health Problems Cancer, Cataracts, Asthma • Animal Health Problems Deformities, Pickled eggs of fish and amphibians, softer eggs in birds • Changes in pH of rain Damage to our property  clothes, cars, tires, paint, statues, pyramids

  3. Photochemical Smog • Makes ‘bad’ ozone from chemical reactions triggered by the sun light and air pollution. http://www.mfe.govt.nz/issues/air/images/summersmog.jpg http://www.pdphoto.org/PictureDetail.php?pg=5215&mat=pdef

  5. Common Chemicals in Photochemical Smog NO2 O3 this is the bad Ozone that damages our lungs and plants. NO http://www.chemistry.wustl.edu/~courses/genchem/Tutorials/AirQuality/intro.htm

  6. Low Pollution vs High Pollution http://www.chemistry.wustl.edu/~courses/genchem/Tutorials/AirQuality/intro.htm

  7. http://www.chemistry.wustl.edu/~courses/genchem/Tutorials/AirQuality/origin.htm view the movie

  8. Photochemical Smog is Always a Reddish-Brownish Color from NO2 Bangkok and Seattle

  9. Photochemical Smog

  10. London Type Fog from Coal Burning http://www.epa.gov/history/topics/perspect/london.htm “The smog even invaded the world of Shakespeare, whose witches in Macbeth chant, "fair is foul, and foul is fair: Hover through the fog and filthy air."

  11. Temperature Inversions: “The Great Smog of 1952” • 12,ooo people died in London when the layers of air inverted (turned upside down) from the usual patterns. • Londoners burned more coal to keep warm. The pollution increased. • Their coal was higher sulfur coal which caused worse polution. • The inversion lingered.

  12. Acid Rain • Solutions(liquids where water is the largest part) can be neutral, acids or bases. • Acids react with metals to make hydrogen gas. • Acids are measure with pH paper and have a range from 17 which is neutral water. • Any pH >7 is a base. • pH paper has chemicals dried on it. Acid and bases cause color changes with the chemicals.

  17. Effects of Acid Rain:http://static.howstuffworks.com/gif/acid-rain-4.jpg Marble reacts with acid. This statue has lasted almost 2000 years until our acid rain problems began.

  18. Effects on animals

  19. Only birds in high acid rain areas were having this problem. Birds eat snails and spiders and insects. Snails could not survive where CaCO3 was leached out of the soil by the acid rain. Spiders and insects did not provide enough calcium for the birds after the snails died out. Birds don’t depend on Calcium from the soil. Why were their eggs shells breaking?

  20. HYPOTHESIS: Increase the calcium in the birds diets and observe the new eggs. Scientists put broken chicken egg shells in the area for the birds to eat. RESULTS: Egg shells became stronger again in the new hatchings and the birds returned to normal.

  21. pH Stomach acid (HCl) is pH = 1.7 The acid dissolves your teeth when you throw up. Rinse your mouth out but don’t brush vigorously when you are sick. pH < 5 water with lower pH has very few insects and almost no clams.

  26. Three possible causes: • Increased UV rays from Ozone Layer problems. • Habitat Destruction

  27. Possible Causes being investigated: • Shifts in parasite populations perhaps are caused from acid rain or other pollutants. Amphibians are at the middle of the lower part of the food chain. This has been happening since the mid 1990’s. This is a concern for us.
