Abstract
This well-researched and detailed paper explores the effects of acidic precipitation (acid rain) which has been a major factor in fish kills throughout countries in the northern hemisphere. The writer of this paper cites numerous studies which have linked aluminum toxicity along with acid rain as the main cause of fish extinction. This paper stresses the urgency in developing a successful management tool in determining the viability of fish populations in various natural settings. This paper also contains detailed information and results of various case studies as well as two graphs that support the author's claims in this report.
From the Paper
"The fish used in this experiment were obtained from a trout farm which ensures the relative similarity of the fishes used in the experiment. They were acclimated to artificial soft water for 2 weeks before they were used in the experiment. They were then transferred to flux chambers for the experiment and given 24 to 48 hours to recover from the handling stress before they were exposed for 24 hours to low-pH water (pH 4.4, 4.8, or 5.2) A control group (N=36) for each of these pHs was left in these conditions for 10 days. The experimental group after this 24 hour exposure to low pH levels were exposed to concentrations of Al of 111, 333, or 1000 ug/L at the same pH (N=72)."

From the Paper
"Acid rain is a major problem facing the environment today. It is formed through both natural and Anthropogenic sources. Industrial emissions are Anthropogenic sources, and a volcano eruption is an example of a natural source. One of the most direct effects of acid rain is on aquatic ecosystems. Among the variety of organisms in aquatic systems effected by acid rain are fish. Acid rain has many toxic effects on fish leading to decrease in their presence, diversity, abundance and well being. ?Biological observations of damaged fish communities in acid waters show that the number of species is less than expected, that the structure of population is anomalous, and productivity and yield are reduced?(Howells, 1995). Acid rain is not a new problem. It?s effects have been observed for centuries. ?As industrialization of Europe developed, other observers in England, Sweden, Austria and Germany confirmed the ?poisonous? nature smoke emissions from various activities?(Howells, 1995). It was a major problem in industrialized cities as far back as the 1800s. "

Abstract
This paper explores how acid rain is produced, what its impact is on the environment, what has been done by government agencies to help the problem, how effective these measures have been, what individuals can do to help reduce this problem, what are the current technologies for reducing emissions and how these technologies can be used to reduce acid rain in the future. It demonstrates that current attempts to reduce emissions from power plants will not have a significant effect on acid rain reduction; and will support the idea that there is not a single solution to the problem of acid rain, but rather a combination of technologies and methods will have to be utilized to have a noticeable effect of the reduction of and repair of environmental destruction caused by acid rain.

From the paper:
"Our modern world has many conveniences. We enjoy hot water, lights, computers, cars, and many other conveniences, which are now an integral part of our society. Many of us cannot imagine life without them. We seldom think about the costs every time we turn on a light. We do not think about the where the electricity is produced and what the effects on the environment might be. We simply turn on the light. As with all good things, there is a cost. One cost of our modern conveniences is acid rain caused by the burning of fossil fuels. The effects of acid rain came into the forefront during the early seventies as its effects began to be noticed on a global level. The impact of the effects of acid rain is considered to be of great concern to some and of little concern to others. No matter which side you are on, we all must agree that energy consumption will continue to increase globally and we must be weary of the effects of energy production and always stay focused on future generations."

Abstract
The following paper examines why environmental scientists are concerned that the level of acidity in rain and snow has increased beyond its normal levels in the United States. The writer discusses the ways in which this has had a serious impact in several areas, including forests in the northeast and many of the country's most valued monuments.
From the Paper
"Munton (1998) expresses the same concerns. He notes that emissions have already been reduced by 50%. That is an impressive improvement, but perhaps still more than delicate ecosystems can stand. He suggests that we may need even more restrictive interventions in place, and points out that modern society?s effects on the atmosphere goes beyond acid rain, which may also affect human health, but to breathable particulates, effects on the ozone layer, and regional haze making particular areas periodically more vulnerable to the effects of airborne pollutants.
"In conclusion, it may be too soon to be satisfied with our efforts so far. Given the tremendous amount of pollution released into the air, a 50% reduction may be a result that looks good on paper but that is still significantly damaging to our environment."

From the Paper
"The harm that acid rain does can be measured tangibly with scientific testing but it also has an intangible impact on the atmosphere as it causes changes to the way things look and feel as well. The beauty of plants and forests and streams can be negatively affected through the damage that acid rain leaves behind (Understanding acid rain http://weather.about.com/library/weekly/aa032502a.htm)."
"One of the more specific issues with acid rains is its ability to cause the acidification of lakes and streams worldwide. It is also causing damage to trees, especially the trees that are found at higher elevations. One example of this is the red spruce trees that are normally located at 2,000 feet above sea level (Effects of Acid Rain http://www.epa.gov/acidrain/effects/index.html)."

Abstract
This paper provides a definition of "acid rain" and how it is formed. It looks at the dangers of acid rain and the damage it is doing to the environment. It briefly examines options and programs that can be performed to reduce acid rain.
From the Paper
"The term ?acid rain? is a little misleading. Rain is naturally acidic, from both carbon dioxide in the air and absorption of chlorine from the ocean (Gordon, 2002). All compounds can be measured for acidity or alkalinity on a Ph scale ranging from 0 ? 14, with anything below 7 showing at least slight acidity. Rain is judged ?acid? when its Ph falls below 5. (Gordon, 2002) Environmental scientists are concerned because in some parts of our country, the level of acidity in rain and snow has increased beyond its normal levels. This has had a serious impact in several areas, including our forests in the northeast and many of our most valued monuments."

Abstract
This paper explains the definition of acid rain which is created mainly by man made pollutants invading the air and its disastrous effect on the environment. The writer of this paper details the effects of acid rain on animals, marine life, lakes, streams and forests while stressing the importance of controlling the spread of this environmentally hazardous phenomenon while examining the different methods currently being used to reduce harmful emissions and pollutants. Includes graphs.
From the Paper
"The Ph of rain is dropping because we add tremendous amounts of material to the air. Some of this is in the form of particles and is pulled back to the earth by gravity, but water-soluble gases such as sulfur dioxide mix with the moisture in the atmosphere and return to the Earth as rain or snow. This return to Earth is called "deposition." (Gordon, 2002) The dust particles can leech into the soil, changing the nutrients available in our forests. One source for these extra elements in the air and precipitation is fossil fuels, fuels such as oil and coal. These fuels release significant amounts of both sulfur dioxide and nitrogen, which become part of our rain and snow."

Abstract
This paper explains that acid rain, a relatively new environmental phenomenon, is caused primarily by human created air pollution and that it presents a serious problem because it destroys the environment, including plant and marine life. The paper talks about the effects of acid rain and how far reaching it is as well as the importance of controlling the problem.
From the Paper
"Acid rain is now commonly perceived as a major environmental threat but the term is still relatively new and many are confused about its causes. While there are some other commonly cited reasons including natural sources, the main cause of acidity in rain is air pollution, which increases the composition of sulphur oxides and nitrogen oxides and thus lowering the pH level to less than 7. Air pollution is defined as "the introduction by humankind, directly or indirectly, of substances or energy into the environment resulting in deleterious effects of such a nature as to endanger human health, harm living resources and eco-systems, impair amenities or interfere with other legitimate uses of the environment."

Abstract
This paper introduces, discusses, and analyzes the topic of acid rain. Specifically, it defines acid rain and discusses its effect on the environment.
From the Paper
"The term "acid rain" is really a bit of a misnomer, because acid "rain" can be either wet or dry, and is a global term that covers almost any type of acid that falls from the atmosphere onto the Earth (EPA). Acid rain is often called "acid deposition" by scientists, but the common term most of the public understands is acid rain. Acid rain is a mixture of sulfur dioxide and nitrogen oxides, which result from burning fossil fuels like coal and oil. These chemicals react as they are released into the atmosphere, and join to create a mild solution of acidic compounds that becomes acid rain when it falls to the ground mixed with precipitation, such as rain, fog, and snow, or falls to the ground on its own if there is enough of it in the air. Acid rain is common all over the world, and as our reliance on fossil fuels grows, so does the potential for increasing acid rain."

Abstract
Due to the fact that the world?s tropical rainforests are located in areas far from the United States, many people ignore the fact that their future may depend on the future of these forests. Rainforests are being destroyed at an increasingly fast pace, much faster than any other ecological zone on earth. This paper examines the effect of acid rain on rainforests, mainly as a large contributor to deforestation, particularly in localized industrial areas in Africa, China, southeast Asia and northern South America.
From the Paper
"Researcher also believe that we should be concerned about the impact of acid rain on forest soils, as there is evidence that acid rain has already caused significant changes in the chemistry of some sensitive soils. As acid rain seeps through the soils, it can erode vital plant nutrients through chemical reactions, presenting a threat to future forest productivity."

Abstract
This ten-page undergraduate paper examines the issue of acid rain in eastern Canada and the New England states. The author notes that acid rain is created through the reaction of air pollutants such as sulfur oxides and nitrogen oxides with water in the air, which forms strong acids such as sulfuric and nitric acid. It spreads across wide geographic areas, making it difficult to conclusively determine who is responsible for damages, thus creating political controversy and complicating efforts to reduce it. While progress has been made in reducing acid rain, much more needs to be done, both politically and in private industry.

From the Paper
"Ever since the 1972 Conference on the Human Environment was held in Stockholm, the international community has made significant progress in understanding the causes and consequences of acid rain. While the world is slowly coming to understand the seriousness of the problem, we continue to pour ever-more sulfur and nitrogen contaminants into the earth's atmosphere. The purpose of this research is to examine the nature and extent of the acid rain problem and to discuss proposed solutions to the problem.
It is imperative that the gap between knowledge and action be closed quickly - otherwise much will be lost. Several important studies funded by the German Marshall Fund, the Organization for Economic Cooperation and Development, The European Economic Community, and other national and international (...)"
