2. Learning Objectives TLW be able to describe sources of air, water, and ground pollutions

3. Combustion Reaction

4. Major Pollutants SO x SO x NO x NO x VOC’s – volatile organic compounds VOC’s – volatile organic compounds Particulates Particulates Ozone (ground level) Ozone (ground level) CO CO

5. Sources of Pollutants From burning of fossil fuels (coal, oil, natural gas) From burning of fossil fuels (coal, oil, natural gas) –SO x –NO x –Particulates –CO 2 From unburned fuels and evaporation of chemicals From unburned fuels and evaporation of chemicals –VOC’s Formed in air from VOC’s and NO x (needs sunlight) Formed in air from VOC’s and NO x (needs sunlight) –Ozone

6. Effects of Pollution Greenhouse effect Greenhouse effect –From CO 2 Acid Rain Acid Rain –From SOx and NOx Ozone layer depletion Ozone layer depletion –From VOC’s Ground level health effects Ground level health effects
