  1. Reducing Acid Rain

  2. Reduce SO2 and NOx • Energy conservation • Use coal containing less sulfur • Use scrubbers in smokestacks • Substitute natural gas for coal • Use catalytic converters in cars • Use alternative energy sources

  3. Is acid rain a global problem? • Reactions of sulfur oxides to from sulfuric acid are quite slow • Sulfur dioxide may stay in the air for 3-4 days • Acid rain from sulfur dioxides can travel hundreds to thousands of miles depending on the winds

  4. Is acid rain a global problem? • Nitrogen oxides remain in the air for about half a day and only travel tens or hundreds of miles

  5. Where is the acid rain? • Prevailing winds of N. America transport pollutants southwest to northeast • The 9 largest coal burning states are in the Midwest and the Ohio River valley • ~2/3 of the acid rain in the Northeast US and Eastern Canada comes from these sources • Destruction of the maple sugar bush in VT, ME, NH, and Quebec has totaled into the billions of dollars

  6. Liming • The only method that can be used to restore acidified lakes, soils, and rivers • Apply crushed limestone onto a field or body of water • Calcium carbonate reacts with the acidity raising the pH • Must be repeated if more acid deposition is received
