• Particulate matter       • Construction and agriculture major
                             contributors
• Carbon monoxide          • Tasteless, odorless, gas that lowers
                             oxygen levels carried by the blood
• Ground level ozone       • Pollutant formed when auto emissions
                             react with oxygen and U.V. rays
                           • Carbon monoxide, sulfur oxides, nitrogen
• Primary air pollutants     oxides

•   Acid                   •   pH less than 7
•   Base                   •   pH over 7
•   Neutral                •   pH of 7
•   Burning fuels          •   Cause of most air pollution

•   Electric power plants           •   Cause of 2/3 of sulfur dioxide

•   Burning fossil fuels            •   Contributes most to acid rain
•   Midwestern and eastern states   •   Most of the acid rain in Canada
                                        is released as pollution from
•   Secondary pollution             •   Ground level ozone in the
                                        presence of sunlight

•   Indoor pollutants               •   Radon and asbestos
•   Transportation                  •   Largest producer of primary air
