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 PollutionFossil 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
