9.2 Smog Heat Island Effect Noise Lights
Smog Dirty clouds of pollution
Industrial Smog Power plants that burn coal and oil Sulfur dioxide (SO2)
Photochemical Smog Burning gasoline Nitrogen oxides (Nox), ozone, PAN React with sun
Ozone Ground level Irritate and damage lungs Difficulty breathing Make asthma symptoms worse
PAN Peroxyacetyl nitrates Respiratory and eye irritants Cause cancer Kill plants
Ozone Levels Monitored everyday Warnings on high days http://www.epa.state.il.us/air/aqi/
Atmospheric Ozone Good Protects earth Radiation
Catalytic Converters Eliminates car emissions Carbon monoxide (deadly) Nitrogen (make smog and acid rain; unhealthy) Hydrocarbons (generate ozone and smog)
Urban Heat Island Effect City is hotter than rural neighbors More dark surfaces to absorb / maintain heat More machines, air conditioners, heaters
Solutions to Heat Island 1.More plants and trees 2.More light surfaces
Noise Pollution Distracting, irritating, or damaging sounds Airplanes, trains Construction Loud music
Decibel (dB) Measures sound 120 dB can cause deafness
Light Pollution City lights on all night Harms nocturnal animals Cant see stars

Urban Air Pollution Nada Nabulsi & Thea Tadros. Sources Particulate Matter: smoke, dirt and dust from factories, farming, and roads Ground Level Ozone.
AIR POLLUTION. Primary vs Secondary Primary pollutants: enter atmosphere directly –Ex: CO 2, NO x, SO x, Particulates and Hydrocarbons Secondary pollutants:
What do you think this means?. Learning Targets 8. Identify the causes and effects of pollution on Earth’s cycles. 9. Explain how pollution affects.
Air Pollution By: Andrew Blake. Primary Information -Measured in ppms (parts per million) -Primary pollutants are emitted directly into the air from natural.
Prepared By- SHAH RAJ SANJAYBHAI Any visible or invisible particle or gas found in the air that is not part of the original, normal composition.
And its Environmental Effects

APES Get out lab – keep at table. SMOG Ch. 18 Smog Localized air pollution in urban areas, mixture of pollutants that form with interaction with sunlight.
SECTION 1.4 Human activities affect the atmosphere.
Air Pollution Air pollution happens when gases and particles enter the air. Burning is the greatest source of air pollution Coal, oil and natural gas,
Urban air pollution and Acid rain. Pollutants Primary – emitted directly exhaust fumes factory chimneys Oil spills Secondary – primary reacts with substances.
What is Air Pollution? What causes Air Pollution? What does Air Pollution do to us? How should we act?
AIR and Air Pollution Health Effects A. Short-term effects reversible 1. headache 2. nausea 3. irritation to eyes, nose, & throat 4. tightness in chest.
