  1. Agenda 4/8 • Test Friday over Air Pollution (notes yesterday, today, and tomorrow!) • Warm-Up: Do you think we have an acid rain problem in Georgia? Why or why not? • Notes: Air, Noise, and Light Pollution • Video with 5-4-3-2-1: Revenge of the Electric Car

  2. Air & Air Pollution Chapter 12, Section 2: Air, Noise & Light Pollution Standards: SEV3a

  3. Who is most affected by air pollution? • Very young • Very old • People with heart or lung problems • People who have asthma

  4. What are the short term effects of air pollution on health? • Headache • Nausea • Irritation of eyes, nose, throat • Coughing • Upper respiratory infections- bronchitis, pneumonia • Worsen effects of asthma & emphysema

  5. What are the long term effects of air pollution? • Emphysema • Lung cancer • Heart disease

  6. Case study: health effects of ground level ozone (aka- bad ozone) • Good ozone is in the stratosphere over Earth’s atmosphere & protects us from UV rays • Ground Level (bad) Ozone = VOC’s + NOx + sunlight • Mostly from cars, gas vapors & power plants • Short term effects: irritation of respiratory system, increased asthma • Long term effects: reduced lung function (especially kids who live in urban areas and are outside often)

  7. What are some types of indoor air pollution? • Sometimes indoor worse than outdoor because more concentrated & more exposure. • Tobacco smoke • Tetrachloroethylene- dry cleaning fluid • Paradichlorobenzene- moth balls & air freshener • Bleach, NaOH- cleaners • NOx- unvented gas stoves, wood stoves • Fungi & bacteria- dirty air conditioning ducts • CO- faulty furnace, cars left running • Formaldehyde- furniture, carpet, particle board • Radon- radioactive soil under foundation

  8. What is radon? • Odorless,colorless • Radioactive • When home is built, radon can be “uprooted” • If basement or floors develop cracks, radon can seep in • If you live in this environment for many years can develop lung cancer. • 2nd leading cause of lung cancer in US • How do you fix it? • Establish ventilation system in basement to release radon so it doesn’t build up in house

  9. What is asbestos? • Long, thin fibers that are able to resist heat • Insulator, fire retardant • Brakes & building materials • Banned in school buildings now. • Inhaling asbestos can cut & scar lungs • Leads to type of lung cancer called mesothelioma Cross section of a lung afflicted with mesothelioma

  10. What is sick building syndrome? • Common in well air conditioned buildings that are closed tight to keep in cool air. • Cause headaches, nausea that are alleviated by going outside • Martin county, Florida- $11 million courthouse closed down due to mold created by air conditioning system with no ventilation. • LA Times- Florida's Plague: Sick Building Syndrome

  11. What is noise pollution? • Unwanted sounds • Irritating to ears & damages cells in ears • Hearing loss has doubled in US in last 30 yrs • 12% teens have permanent hearing loss • Measured in decibels (dB) • See table • 120 dB is threshold of pain • Europe MP3 players cannot produce more than 100 dB of noise • National Institute of Health sets safe threshold at 85dB for 8 hours • US does not regulate personal listening devices.

  12. What is light pollution? • Does not present direct danger to human health. • Problems with light pollution: • Aesthetic reasons- can’t see stars at night • Wasted energy when shines upward • Shield light so it is focused downward • Use timer controls • Use low pressure sodium light sources to save energy

  13. You should be able to… • Describe the long term and short term effects of air pollution on health. • Describe two ways in which indoor air pollution can be prevented • Describe some of the human health problems caused by noise pollution • Describe several solutions to the energy waste associated with light pollution.

  14. 5-4-3-2-1 on your own paper 5 Things you learn about electric cars from the video 4 way the technology for electric cars is changing/improving 3 car companies that get mentioned in the video 2 ways you could change your own habits to improve air quality 1 sentence answering this question: Would you buy an electric car? Why or why not?
