Presentation Transcript

  1. 9.3 Acid Rain

  2. pH Scale • Ranges from 0 to 14. • pH of 7 = neutral (pure water) • 0-6 is acidic

  3. Acid Deposition • From SO2 and Nox • Cars, industrial smelting, refining and electric power plants • SO2 and Noxcombine with water vapor

  4. Dangerous pH • Below 5.6 pH • Wet and dry deposition

  5. Wet Deposition • Falls with rain or in clouds

  6. Dry Deposition • No rain • Particles or gas with acid • Stick to ground, plants, or surfaces

  7. Plants • Roots damaged • Growth stunted • Nutrients destroyed • Organisms in soil killed • Damages outer layer • Weak or dead plants

  8. Animals • Animals and birds dependent on the water for food sources or as a habitat, die • This moves through the chain

  9. Aquatic Life • Leaches mercury and aluminum • Poisons fish, plankton, insects

  10. City Buildings • Paint peels off • Cars fade • Corrosion of statues and structures • Old temples, art ruined • Books and manuscripts ruined

  11. Geography • Poland • Europe • Chine • Canada • United States

  12. Smokestack Scrubbers • Wet limestone absorbs sulfur • Cloth filters catch other particles • Reduce sulfur up to 90%
