Dangerous Outdoor Air Pollutants:
- Particulate matter (small molecules of dust, dirt, soot, and smoke in the air)
- Ground Level Ozone (the main ingredient in smog)
- Nitrogen dioxide (primarily found in fertilizers)
- Sulfur Dioxide (from the burning of fossil fuels)
Sources of Outdoor Air Pollutants:
Transportation: Vehicles emit harmful substances such as carbon monoxide, nitrogen oxides, and particulate matter into the air, contributing to air pollution.
Industrial activities: Manufacturing, construction, and other industrial activities release harmful chemicals into the air, including sulfur dioxide and particulate matter.
Power generation: Power plants that rely on fossil fuels, such as coal and natural gas, release harmful chemicals and particulate matter into the air.
Agriculture: Livestock production and the use of fertilizers can release harmful chemicals into the air.
Natural sources: Forest fires, dust storms, and volcanic eruptions can also contribute to air pollution.
