  1. RaeAnne Bollinger Geography 1000 AIR QUALITY

  2. INVERSIONS IN UTAH • During the winter, Utah is among the top 25 worst cities in the U.S. • Current air pollution estimates that lives are shortened by 2 years! • Compare this pollution to smoking a pack of cigarettes a day!

  3. What is pollution? • Small & Coarse particles • Ozone • Oxides of nitrogen and sulfur • Toxic metals such as mercury and lead.

  4. TYPES OF POLLUTION • Primary pollution- contaminates released directly into the air • Secondary Pollution- form due to chemical reactions or other processes in the atmoshere.

  5. Primary Pollution Examples -Particles -Sulfur Compounds -Nitrogen Compounds -Carbon Oxides -Hydrocarbons

  6. Secondary Pollution Example • Photochemical Smog -Gases reacting to ultraviolet radiation in strong sunlight.

  7. Pollutants • Semi Trucks • Buses • Automobiles • Refineries • Coal fired power plants.

  8. NATURAL POLLUTANTS SALT VOLCANIC ASH SMOKE DUST PARTICLES

  9. Warm Weather Pollution • Large amounts of urban pollution cause the most common air alert because of the photo-chemical process. • Humans add oxides to the air which sunlight reacts to and produces ozone near the ground.

  10. Cold Weather Pollution • Temperature inversions cause the most serious air conditions. • Inversions occur when the surface air is cooler than the air above. • With cold air below and warm above, surface air does not have any reason to rise and clear out local ground-level air pollution.

  11. Ozone is corrosive and noxious and we experience this when ground-level ozone is present. • Our goal is to keep ozone up in the atmosphere where it can do its job.

  12. Humans need to avoid producing unnecessary ground-level ozone and protect the atmospheric ozone. • International agreements have banned production of CFC Chemicals that damage the ozone.
