  1. Acid Deposition Made by: Adriana Chacón Carmen Araujo

  2. Acidity • Acids are chemicals that are able to donate a hydrogen ion to other chemicals http://www.youtube.com/watch?v=WOHJXyhe2Tk&feature=related

  3. Isthe general termforacidcomingdowntotheEarth’ssurfacefromthe air • Wetdeposition- theacid comes down in theform of rain orsnow • Drydeposition- theacid comes down as gas ordryparticles, withoutwater AcidDeposition

  4. Main Pollutants & Sources

  5. Acid deposition and its effects • Human construction • Limestone buildings and statues dissolve because of the acid.

  6. Effect on coniferous forests • 1970s: Germany’s Black Forest was damaged. • All kinds of trees suffered physical damage. • Loss of chlorophyll, lesions and thinning of wax cuticles. • Availability of nutrients reduces growth even more. • Reduces availability of soil particles therefore nutrients are also not available. • Root hair damaged • Damage of trees can kill them

  7. Effect on fish & other aquatic organisms • Aluminum released from soil ends up in the streams and rivers. • Fish’s ability to regulate amount of salt and water in its body, affects intake of oxygen and salt. • This may lead to death of fish.A solid can form on the fish’s gills, causes suffocation. No longer breathe.

  8. Reducing ability of soil particles to hold on to nutrients. • Nutrients: calcium, magnesium and potassium ions. Effects on soil fertility through nutrient removal
