12-3 Acid Precipitation Page 314
A. What causes acid precipitation? • 1. Precipitation (rain, snow, or sleet) that contains a high concentration of acids.
A. What causes acid precipitation? • 2. Burning of fossil fuels releases nitrogen and sulfur which combine with water vapor in the atmosphere.
A. What causes acid precipitation? • 3. Sulfuric and Nitric acids form and fall as acid rain.
A. What causes acid precipitation? • 4. pH can be used to measure how acidic(1-6) or basic (8-14) a substance is.
A. What causes acid precipitation? • 5. Pure water is neutral and has a pH of 7.
B. How acid precipitation affects soils and plants • 1. It lowers the pH of soil and water.
B. How acid precipitation affects soils and plants • 2. An increase in the concentration of acid is called acidification.
B. How acid precipitation affects soils and plants • 3. Plants suffer because some nutrients get dissolved and washed away while the roots become damaged.
C. Acid Precipitation and Aquatic Ecosystems • 1. Ph levels that are too low kill fish.
C. Acid Precipitation and Aquatic Ecosystems • 2. Acid also causes aluminum to leave soil and enter water source which slowly suffocates fish by getting stuck in their gills.
C. Acid Precipitation and Aquatic Ecosystems • 3. In the spring, acidic ice from winter melts and enters water which causes acidic shock (sudden increase of acid).
D. Acid Precipitation and Humans • 1. Released aluminum and mercury may find its way into fish, crops, and water.
D. Acid Precipitation and Humans • 2. Possibly linked to respiratory diseases.
D. Acid Precipitation and Humans • 3. Negatively affects fisheries and forestry.
D. Acid Precipitation and Humans • 4. Dissolves calcium carbonate which is common in concrete, marble, and limestone.
E. International Conflict and Cooperation • 1. One problem with acid precipitation is that pollutants may be released in one spot and fall in another spot.
E. International Conflict and Cooperation • 2. For example, some acid rain that falls in Canada in produced by the US. • 3. The Canada-U.S. Air Quality Agreement was signed in 1991.
