AP Environmental Science Pollution Review

Here's an organized outline for AP Environmental Science Unit 7 reviews. This outline has been adapted from the 2019 Course Description published by College Board. You can use this to build an AP Enviro Unit 7 study guide.

Causes of Pollution

Human activities affect the quality of the air both indoors and outdoors. 

  • Burning fossil fuels releases nitrogen oxides into the atmosphere where they lead to the production of photochemical smog by producing ozone.

  • Areas with large number of vehicles like cities often have more photochemical smog.

  • Common indoor air pollutants include Volatile Organic Compounds (VOCs), formaldehyde and lead. Air pollution can be in the form of gases or particulates in the atmosphere and be generated by both natural and human sources.

  • CO2 appears naturally in the atmosphere from respiration, decomposition, and volcanic eruptions.

  • CO2 concentrations in the atmosphere have increased from the burning of stored carbon (fossil fuels). ⚡ Watch: AP Environmental Science - 🎥 Air Pollution 

Solving Pollution

Legislation has been put into place in order to protect air quality.

Unit 7 Vocab

  • Acid rain
  • Clean Air Act
  • Effects of air pollutants
  • Environmental Protection Agency (EPA)
  • Indoor air pollutants
  • Methods to reduce air pollutants
  • Natural sources of CO2
  • Noise pollution
  • Photochemical smog
  • Primary Air pollutants
  • Secondary air pollutants
  • Sources of air pollutants
  • Thermal inversion
  • Volatile Organic Compounds (VOCs)
