BIOL 101 Lecture Notes - Lecture 1: Hydrogen Sulfide, Sulfur Dioxide, Particulates
Document Summary
Air pollution is any contamination of the atmosphere that disturbs the natural composition and chemistry of the air. Natural sources for air pollution: volcanoes, fires, dust storms, living and dead organisms. Ash, water vapor, carbon dioxide, sulphur dioxide, hydrogen sulfide, carbon monoxide, hydrogen, chloride, and hydrogen sulfide. Humans release more co2 than volcanoes do as year. 2. 7 days for anthropogenic (human made) co2 to equal a years-worth of co2 given off by volcanoes. Anthropogenic sources: industrial, cars, fossil fuels that have been burned, even carpets and plastic. Fine particulate matter (pm 2. 5) is a(cid:374) air polluta(cid:374)t that is a co(cid:374)cer(cid:374) for people"s health. Ozone (o3) is a gas molecule composed of three oxygen atoms. When gases that come out of tailpipes and smokestacks come in contact with sunlight, they react and form ozone smog.
