Air Pollution = the release of damaging materials into the atmosphere.
Primary Air Pollutants: released directly into the air PollutantDescriptionSourceEffect Carbon Monoxide Sulfur Dioxide Nitrogen Dioxide Volatile Organic Compounds Particulate Matter Lead PollutantDescriptionSourceEffect Tropospheric Ozone Sulfuric Acid & Nitric Acid Secondary Air Pollutants: when primary air pollutants react chemically with other substances
Primary Air Pollutants: released directly into the air PollutantDescriptionSourceEffect Carbon Monoxide (CO) *colorless, odorless *gas *incomplete combustion of fossil fuels *vehicles, industry, etc… *binds to hemoglobin (blood can’t carry oxygen to body) Sulfur Dioxide (SO 2 ) Nitrogen Dioxide (NO 2 ) Volatile Organic Compounds (VOC) Particulate Matter Lead (Pb)
