  1. Air Pollution Objective: TSWBAT understand how air pollution effects health status. TSWBAT identify different sources of air pollution. TSWBAT evaluate how you create air pollution everyday and how we can change our habits to limit/eliminate the pollution.

  2. What is air pollution? • Contamination of the air that causes negative effects of life and health

  3. Atmosphere • Layer of gas that surrounds the earth • Waste substances enter atmosphere and pollute the air we breath

  4. Cilia • Hair-like structures that remove dust and other particles from the air • Pollutants damage or destroy cilia • Leads to asthma, emphysema, bronchitis, & lung cancer

  5. Sources of Air Pollution • Fossil Fuels • formed from plant/animal remains (coal, oil, gasoline, natural gas) • Carbon Monoxide • odorless, colorless, tasteless gas • reduces ability of blood to carry oxygen to body cells

  6. Sources of Air Pollution • Sulfur oxides • sulfur containing chemicals that irritate nose, throat & eyes, • smell like rotten eggs • Nitrogen oxides • nitrogen containing chemicals • irritate the respiratory system • appears as a yellow brown haze in the atmosphere

  7. Sources of Air Pollution • Acid Rain • rain or other form of precipitation that has a high acid content. Acid rain decays plants and crops • Particulates • tiny particles in air (soot, ash, dust, pollen)

  8. Sources of Air Pollution • Motor Vehicle Emissions • substances released into the atmosphere by motor vehicles with gasoline engines • Contain carbon monoxide, sulfur oxides, and nitrogen oxides

  9. Sources of Air Pollution • Smog • combo of smoke and fog • in sunlight, the water vapor in the air, motor vehicle conditions, & smoke particles combine to form smog • Thermal Inversion • occurs when a layer of warm air forms above a layer of cool air • air cannot circulate and pollutants are trapped in cooler layer

  10. Sources of Air Pollution • Ozone • form of O2 • Most is found in upper atmosphere where it is produced naturally • helps protect earth from sun’s rays

  11. Sources of Indoor Air Pollution • Second Hand Smoke • exhaled or side stream smoke. Major cause of lung cancer • Group A Carcinogen • substance that causes cancer in humans

  12. Sources of Indoor Air Pollution • Formaldehyde • colorless gas with a strong odor. • found in plywood, upholstery, carpets • Asbestos • heat resistant mineral found in many building materials • found in older homes, heating systems, insulation. • linked to lung cancer

  13. Sources of Indoor Air Pollution • Radon • odorless, colorless, radioactive gas • released by rocks and soil • enters homes through cracks in the floor and wall. • Sick Building Syndrome • illness that results from indoor air pollution

  15. Global Environmental Issues: • Population Growth vs. CO2 Emissions • http://www.breathingearth.net/

  16. How can we keep the air clean? After reviewing the terms and viewing the pictures & websites about Air Pollution, write down on your notes outline 8 ways you can reduce air pollution in your everyday life:

  17. Don’t smoke Support ‘Clean Indoor Act’ Avoid car running when not being driven Don’t drive a ‘clunker’ Service your car Avoid driving at high speeds Walk or ride your bike Use public transportation Carpool Plant trees Check home for asbestos & radon Install carbon monoxide detectors Check sources of heat regularly in home Limit toxic fume household cleaners Don’t burn trash or yard waste
