Study Notes

Air pollution is a significant health and environmental threat, caused both by natural sources and human activities.
Human-made air pollution accounts for a large portion of overall pollution, stemming largely from energy production.
Burning fossil fuels for energy leads to the release of greenhouse gasses, such as carbon dioxide, methane, nitrous oxide, and fluorinated gasses.
These greenhouse gasses trap heat in the Earth's atmosphere, contributing to rising global temperatures and a cycle of air pollution and climate change.
Air pollution from human activities also leads to smog and toxic pollutants.
Smog, a type of air pollution, can be divided into sulfurous and photochemical smog.
Sulfurous smog is caused by sulfur oxides produced from burning sulfur-bearing fossil fuels like coal.
Photochemical smog, or ground-level ozone, forms through the reaction of sunlight and nitrogen oxides and volatile organic compounds.
Nitrogen oxides originate from car exhaust, coal power plants, and industrial emissions, while volatile organic compounds come from gasoline, paints, solvents, and other sources.
Smog negatively impacts visibility, harms plants, irritates the eyes, and causes respiratory distress.
Toxic pollutants, such as mercury, lead, dioxins, and benzene, are released during gas or coal combustion, waste incineration, and gasoline burning.
Toxic air pollution poses serious health risks, including cancer, reproductive complications, and birth defects.
Solutions to address air pollution include decreasing the use of fossil fuels in transportation, manufacturing, and electricity generation, as well as implementing regulations to limit toxic pollutants.
