NAME___________________________ UNIT 7: Chapter 15 Air Pollution: Objectives: Identify major air pollutants. Describe photochemical smog’s development and effects on the environment. Identify and explain good and bad ozone. Explain the hazards of indoor air pollution. Notes: Read page 409: Cleaning up the Chattanooga o Identify the problem(s) and explain the environmental impact. o How did Chattanooga correct their problem? Your own notes: pages 410-430 Fill in the attached chart – air pollutants Draw and label figure 15.7, page 418 AND figure 15.9, page 419 Terms: Particulate matter (PM) Secondary pollutants Ozone Acid deposition Photochemical oxidants Baghouse filter Smog Electrostatic precipitator Photochemical smog Scrubber Brown smog UV-A Gray smog UV-B Volatile organic compounds UV-C Primary pollutants Chlorofluorocarbons (CFCs) Assignment(s): Multiple Choices page 432-433 #1-18 FRQ (see other side) Score __________________/75 Free Response Question In the mid 1970’s, Sherwood Rowland and Mario Molina predicted a thinning of the stratospheric ozone layer over Antarctica. The thinning was confirmed in the last twentieth century and has continued into the twenty-first century. (A) Identify the class of chemical compounds that is primarily responsible for the thinning of the stratospheric ozone layer and describe TWO major uses for which these chemicals were manufactured. (B) Describe how the chemical compounds that you identified in part (A) destroy stratospheric ozone molecules. You may include chemical equations as part of your answer. (C) Identify the major environmental consequence of the depletion of stratospheric ozone and describe TWO effects on ecosystems and/ or human health that can result. (D) Ozone formed at ground level is a harmful pollutant. Describe TWO effects that ground-level ozone can have on ecosystems and/ or human health.
