A IR & A IR P OLLUTION Chapter 12, Section 2: Air, Noise
& Light Pollution Standards: SEV3a
Slide 3
W HO IS MOST AFFECTED BY AIR POLLUTION ? Very young Very old
People with heart or lung problems People who have asthma
Slide 4
W HAT 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
Slide 5
W HAT ARE THE LONG TERM EFFECTS OF AIR POLLUTION ? Emphysema
Lung cancer Heart disease
Slide 6
C ASE STUDY : HEALTH EFFECTS OF GROUND LEVEL OZONE ( AKA - BAD
OZONE ) Good ozone is in the stratosphere over Earths atmosphere
& protects us from UV rays Ground Level (bad) Ozone = VOCs +
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)
Slide 7
W HAT 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
Slide 8
W HAT 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. 2 nd leading cause of lung cancer in US
How do you fix it? Establish ventilation system in basement to
release radon so it doesnt build up in house
Slide 9
W HAT 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
Slide 10
W HAT 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 LA Times- Florida's
Plague: Sick Building Syndrome
Slide 11
W HAT 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.
Slide 12
W HAT IS LIGHT POLLUTION ? Does not present direct danger to
human health. Problems with light pollution: Aesthetic reasons-
cant 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
Slide 13
Y OU 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.

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?
