Topic 7.1: Introduction to Air Pollution
Learning Objective: STB-2.A
Identify the sources and effects of air pollutants.
Essential Knowledge: STB-2.A.1
Coal combustion releases air pollutants including carbon dioxide, sulfur dioxide, toxic metals, and particulates.
Essential Knowledge: STB-2.A.2
The combustion of fossil fuels releases nitrogen oxides into the atmosphere. They lead to the production of ozone, formation of photochemical smog, and convert to nitric acid in the atmosphere, causing acid rain. Other pollutants produced by fossil fuel combustion include carbon monoxide, hydrocarbons, and particulate matter.
Essential Knowledge: STB-2.A.3
Air quality can be affected through the release of sulfur dioxide during the burning of fossil fuels, mainly diesel fuels.
Essential Knowledge: STB-2.A.4
Through the Clean Air Act, the Environmental Protection Agency (EPA) regulated the use of lead, particularly in fuels, which dramatically decreased the amount of lead in the atmosphere.
Essential Knowledge: STB-2.A.5
Air pollutants can be primary or secondary pollutants.
