Topic 7.2: Photochemical Smog
Learning Objective: STB-2.B
Explain the causes and effects of photochemical smog and methods to reduce it.
Essential Knowledge: STB-2.B.1
Photochemical smog is formed when nitrogen oxides and volatile organic hydrocarbons react with heat and sunlight to produce a variety of pollutants.
Essential Knowledge: STB-2.B.2
Many environmental factors affect the formation of photochemical smog.
Essential Knowledge: STB-2.B.3
Nitrogen oxide is produced early in the day. Ozone concentrations peak in the afternoon and are higher in the summer because ozone is produced by chemical reactions between oxygen and sunlight.
Essential Knowledge: STB-2.B.4
Volatile Organic Compounds (VOCs), such as formaldehyde and gasoline, evaporate or sublimate at room temperature. Trees are a natural source of VOCs.
Essential Knowledge: STB-2.B.5
Photochemical smog often forms in urban areas because of the large number of motor vehicles there.
Essential Knowledge: STB-2.B.6
Photochemical smog can be reduced through the reduction of nitrogen oxide and VOCs.
Essential Knowledge: STB-2.B.7
Photochemical smog can harm human health in several ways, including causing respiratory problems and eye irritation.
