1. Wednesday, 9/24/2014 1.Set up pg.25 of INB (just the top) Do not set up for CN. OBJ = SWBAT identify major air pollutants and explain their effect on humans Topic = Air Pollutants

2. Wednesday, 9/24/2014 In Class: 1.Create data table 2.Air pollutants Homework: 1.Make sure your INB has been corrected from the first check to now. 2.Study your flashcards

3. Air Pollution = the release of damaging materials into the atmosphere.

4. 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

5. 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)
