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.
Air Pollution
What is air pollution?
Contamination of the air that causes negative effects of life and health
Atmosphere
Layer of gas that surrounds the earth
Waste substances enter atmosphere and pollute the air we breath
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
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
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
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)
Sources of Air Pollution
Motor Vehicle Emissionssubstances released into the
atmosphere by motor vehicles with gasoline engines
Contain carbon monoxide, sulfur oxides, and nitrogen oxides
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
Sources of Air Pollution
Ozoneform of O2Most is found in upper atmosphere
where it is produced naturallyhelps protect earth from sun’s rays
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
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
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
