It poses new challenges to the full development of our forest, agricultural, and aquatic resources; and to the use of fossil fuels as an energy source. The objective of our research program is to develop information which will assure that the Nation's energy needs are met without sacrificing environmental quality.
Share What is Acid Rain? Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms.
This can include rain, snow, fog, hail or even dust that is acidic. What Causes Acid Rain? Acid rain results when sulfur dioxide SO2 and nitrogen oxides NOX are emitted into the atmosphere and transported by wind and air currents. These then mix with water and other materials before falling to the ground.
While a small portion of the SO2 and NOX that cause acid rain is from natural sources such as volcanoes, most of it comes from the burning of fossil fuels.
Burning of fossil fuels to generate electricity. Vehicles and heavy equipment. Manufacturing, oil refineries and other industries. Winds can blow SO2 and NOX over long distances and across borders making acid rain a problem for everyone and not just those who live close to these sources.
Forms of Acid Deposition Wet Deposition Wet deposition is what we most commonly think of as acid rain. The sulfuric and nitric acids formed in the atmosphere fall to the ground mixed with rain, snow, fog, or hail.
The acidic particles and gases may deposit to surfaces water bodies, vegetation, buildings quickly or may react during atmospheric transport to form larger particles that can be harmful to human health. When the accumulated acids are washed off a surface by the next rain, this acidic water flows over and through the ground, and can harm plants and wildlife, such as insects and fish.
The amount of acidity in the atmosphere that deposits to earth through dry deposition depends on the amount of rainfall an area receives. For example, in desert areas the ratio of dry to wet deposition is higher than an area that receives several inches of rain each year.
Measuring Acid Rain Acidity and alkalinity are measured using a pH scale for which 7. The lower a substance's pH less than 7the more acidic it is; the higher a substance's pH greater than 7the more alkaline it is. Normal rain has a pH of about 5. Acid rain usually has a pH between 4.
Unlike wet deposition, dry deposition is difficult and expensive to measure. When acid deposition is washed into lakes and streams, it can cause some to turn acidic.
The Long-Term Monitoring LTM Network measures and monitors surface water chemistry at over sites to provide valuable information on aquatic ecosystem health and how water bodies respond to changes in acid-causing emissions and acid deposition.The ecological effects of acid rain are most clearly seen in the aquatic, or water, environments, such as streams, lakes, and leslutinsduphoenix.com rain also falls directly on aquatic habitats.
Most lakes and streams have a pH between 6 and 8, although some lakes are naturally acidic . Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms.

The effects of overly acidified precipitation (commonly known as acid rain) are slowly and insidiously wearing down the environment, affecting places in almost every continent. A) Acidified lakes characteristically have elevated concentrations of dissolved aluminum ion, Al3, and it is now known that many of the biological effects of acid rain are due to .
This acid precipitation, more commonly known as acid rain, may have severe ecological impacts on widespread areas of the environment. Hundreds of lakes in North America and Scandanavia have become so acidic that they can no longer support fish life.
