3. Effects on Trees and Soil Effects on Trees and Soil -Acid rain causes many effects on forest ecosystems. It caused Europe billion dollars of damage in 1990. -Acid rain causes many effects on forest ecosystems. It caused Europe billion dollars of damage in 1990. -The greatest effects of acid rain are usually seen downwind from polluting regions, and where soil has no buffering capability. -It is theorized that the mechanism of forest damage is caused by: -It is theorized that the mechanism of forest damage is caused by: a. direct damage to foliage a. direct damage to foliage b. the leaching of nutrients from soil b. the leaching of nutrients from soil c. aluminum toxicity c. aluminum toxicity d. increased forest vulnerability d. increased forest vulnerability

4. Influence of trees on soil acidification in base-poor soils

5. Effects on Humans Effects on Humans - Acid rain not only damages plants but there is an effect on food crops as well. Acid rain depletes minerals from the soil and then it stunts the growth of the plant. Due to the stunt of plant growth, acid rain most definitely affects humans food crops and even source of food.

6. To be considered acid precipitation, the precipitation has to To be considered acid precipitation, the precipitation has to have a pH of 5.0 or lower. Aquatic vegetation and animal life vary in their changes in pH; vary in their changes in pH; some species are more acid-tolerant than others. Aquatic systems that are well-buffered may Aquatic systems that are well-buffered may not be as affected by acid rain than those that lack a buffering capacity. In lakes and streams whose waters In lakes and streams whose waters become acidified by acid rain, their microorganisms may be affected by the rain. Effects on Aquatic Systems

7. Chemist Acid rain refers to all types of precipitation-- rain, snow, sleet, hail, fog--that is acidic in nature. Acidic means that these forms of water have a pH lower than the 5.6 average of rainwater. Acid rain damages buildings and monuments, corrodes copper and lead piping, damages such man-made things as car, reduces soil fertility and can cause toxic metals to leach into underground drinking water sources.

8. What the difference? Rain is naturally acidic because carbon dioxide, found normally in the atmosphere, reacts with water to form carbonic acid. While "pure" rain's acidity is pH 5.6-5.7, actual pH readings vary from place to place depending upon the type and amount of other gases present in the air, such as sulphur oxide and nitrogen oxides Rain is naturally acidic because carbon dioxide, found normally in the atmosphere, reacts with water to form carbonic acid.

9. How it happens Scientists discovered, and have confirmed, that sulfur dioxide (SO2) and nitrogen oxides (NOx) are the primary causes of acid rain. In the US, About 2/3 of all SO2 and 1/4 of all NOx comes from electric power generation that relies on burning fossil fuels like coal.

10. what you can do to help Turn off lights, computers, and other appliances when you're not using them. Turn off lights, computers, and other appliances when you're not using them. Use energy-efficient appliances: lighting, air conditioners, heaters, refrigerators, washing machines, etc. For more information, see EPA’s Energy Star program Only use electric appliances when you need them.

Keep your thermostat at 68°F in the winter and 72°F in the summer. You can turn it even lower in the winter and higher in the summer when you are away from home.

12. Sulfur dioxide-caused acid rain has cost China an annual economic loss of over 110 billion yuan (13.3 billion US dollars), and since it is so difficult to measure the affect of acid rain in the US we us china as a way to help estimate the amount of acid rain damage in the US today.

13. Health Officer Acid rain is a big problem that effects the human body. Acid rain looks, feels, and tastes just like regular rain and it doesn’t matter if you walk or swim in acid rain it just harms you if you inhale the fumes.

14. Effects on the Human Body Acid rain could help you develop Asthma, lung disease, lung inflammation, and emphysema. Acid rain could help you develop Asthma, lung disease, lung inflammation, and emphysema. People have died from premature heart, asthma, bronchitis, and lung disorders.
