Acid Rain One World Essay Topics

topic 6.4: acid deposition

image from acidrainisbad.webs.com
Acid rain is a broad term referring to a mixture of wet and dry deposition (deposited material) from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. The precursors, or chemical forerunners, of acid rain formation result from both natural sources, such as volcanoes and decaying vegetation, and man-made sources, primarily emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) resulting from fossil fuel combustion.

When sulfur dioxide and nitrogen oxide emitted by cars and factories combine with moisture in the air, acid rain is formed. Acid rain, which often falls far from the source of pollution, kills trees, makes lakes unfit for fish, and even dissolves the stone in buildings and monuments. Rocky areas with thin topsoil are particularly apt to be damaged by acid rain. 

In this unit we will look at the formation of acid rain, its effects on the ecosystem and strategies to reduce acid rain formation.

​This unit is a minimum of 2.5 hours.

Knowledge and Understanding
U 6.4.1 The combustion of fossil fuels produces sulfur dioxide and oxides of nitrogen as primary pollutants. These gases may be converted into secondary pollutants of dry deposition (such as ash and dry particles) or wet deposition (such as rain and snow).
[The use of chemical symbols, formula or equations is not required]

Refer to the conversion of sulfur dioxide and oxides of nitrogen (NOx) into the sulfates and nitrates of dry deposition and the sulfuric and nitric acids of wet deposition. Knowledge of chemical equations is not required.

Acid deposition can be either wet or dry:
  • Wet deposition - acidic rain, snow, or other precipitation
  • Dry deposition - acidic gas or dry particles, not mixed with water

Primary pollutants - those directly emitted by a factory or automobile, such as...
  • SO2 - sulfur dioxide
  • NO and NO2, usually identified as NOx

Secondary pollutants - primary pollutants react with other substances in the atmosphere and create different pollutants, such as...
  • H2SO3 - sulfurous acid
  • H2SO4 - sulfuric acid
  • HNO3 - nitric acid


U 6.4.2 The possible effects of acid deposition on soil, water and living organisms include:
  • direct effect—for example, acid on aquatic organisms and coniferous forests
  • indirect toxic effect—for example, increased solubility of metal (such as​ aluminium ions) on fish
  • indirect nutrient effect—for example, leaching of plant nutrients.
Acid rain directly affects the chemical and pH balances in ground water. The excess aluminum created by acid rain makes aquatic environments such as the sea, lakes, and streams, toxic. The animals that can withstand the imbalance of the water's natural minerals might survive, but quickly lose their food source as the weaker creatures die off.  

Acid rain leaches calcium out of the soil when it is absorbed by the earth. This directly affects the mineral levels of the soil and the creatures, such as snails, that rely on that calcium for shell growth. Consequently, snails die off and birds, which eat them for calcium, lay eggs with shells that are weak and brittle and therefore fail to hatch.

Acid rain directly impacts forest ecosystems and their inhabitants. Acid rain damages leaves as it falls. Acid rain runoff from the trees and forest floors infiltrates the forest's water supplies; runoff that doesn't enter the water supply is absorbed by the soil.

Acid rain is dangerous to humans. The same sulphate and nitrate particles that directly affect the soil and water pH balances can cause serious damage to the respiratory system if inhaled deeply. A damaged respiratory system means decreased oxygen in the blood supply, which eventually damages the heart.


U 6.4.3 The impacts of acid deposition may be limited to areas downwind of major industrial regions but these areas may not be in the same country as the source of emissions.
Refer to areas downwind of major industrial regions that are adversely affected by acid rain and link them to sources of sulfur dioxide and nitrogen dioxide emissions. Consider the effect of geology (rocks and soils) on water acidity
through buffering.
  • Acid precipitation falls back to Earth rather than entering stratospheric jet stream
  • most areas are downwind of pollution sources
  • Canadian forests damaged by coal-fired power plants in USA
  • Scandinavian and German forests damaged by British coal plants
U 6.4.4 Pollution management strategies for acid deposition could include:
  • altering human activity—for example, through reducing use, or using alternatives to, fossil fuels; international agreements and national governments may work to reduce pollutant production through lobbying
  • regulating and monitoring the release of pollutants—for example, through the use of scrubbers or catalytic converters that may remove sulfur dioxide and oxides of nitrogen from coal-burning powerplants and cars.
  • Reducing use of fossil fuels
  • Reduce the number of cars
  • Switch to low sulfur fuel
  • Remove sulfur before combustion
  • Remove sulfur from waste gases
  • Wet scrubbing
  • Dry scrubbing


​U 6.4.5 Clean-up and restoration measures may include spreading ground limestone in acidified lakes or recolonization of damaged systems—but the scope of these measures is limited.
Use of limestone or lime, a process called liming, is a practice that people can do to repair the damage caused by acid rain to lakes, rivers and brooks. Adding lime into acidic surface waters balances the acidity. It’s a process that has extensively been used, for instance in Sweden, to keep the water pH at optimum. Even though, liming is an expensive method and has to be done repeatedly. Furthermore, it only offers a short-term solution at the expense of solving the broader challenges of SO2 and NOx emissions and risks to human health. Nevertheless, it helps to restore and allow the survival of aquatic life forms by improving chronically acidified surface waters.
A 6.4.1 Evaluate pollution management strategies for acid deposition.
[Reference to Figure 3 Pollution Management]​
Measures to reduce fossil fuel combustion should be considered, for example, reducing demand for electricity and private cars and switching to renewable energy. Refer to clean-up measures at “end of pipe” locations (points of emission). Consider the role of international agreements in effecting change. The cost-effectiveness of spreading ground limestone in Swedish lakes in the early 1980s provides a good case study.

Replace
  • switch to renewable energy sources (reduce fossil fuel use)
  • increase energy efficiency (better light bulbs and appliances)
  • more public transportation (fewer automobiles on the road)
  • use low-sulfur fuels
  Regulate
  • install ‘scrubbers’ on smokestacks of coal-fired power plants to remove SO2
  • catalytic converters installed on automobiles (required by law in the US, Canada, and Europe)
Restore
  • add lime to acidified lakes and streams
  • add lime to forestry plantations (why not natural forests?)
  • UN Convention on Long-Range Transboundary Air Pollutants (LRTAP) - 1979; subsequently amended and modified by US, Canada, and Europe
Thing to consider when evaluating
  • Acid deposition travels with wind and water vapor in the atmosphere
  • The additional environmental impacts of cleaning up emissions e.g. mining, baking and transporting of limestone
  • Monitoring and identify sources may be difficult, as they are often non-point
  • Intergovernmental agreements often require proof and appropriate compensation
International-mindedness:
  • The polluting country and the polluted country are often not the same: acid deposition affects regions far from its source. Therefore, solving this issue requires international cooperation.
  • To what extent does the recognition of the ethical responsibility of knowledge influence the further production or acquisition of knowledge?
image from ecopolproject.blogspot.com
Most cases of non‑point source pollution exemplify well the intractable ethical problem of the “tragedy of the commons”. That is to say, an individual polluting a common resource suffers little themselves from their own pollution and yet may benefit considerably in other ways. Therefore, those that do not pollute are doubly penalized—they suffer the pollution, and yet gain no benefit from polluting the resource themselves. There is thus a net advantage for any individual who does pollute. Ultimately, as many individuals adopt the most advantageous attitude, this leads to a great deal of suffering for all. It is exactly this conundrum that underlies much of the difficulty in managing non‑point source pollution of shared resources on both a local (for example, a river) and an international (for example, the atmosphere) scale. Indeed, that one nation may gain considerably from non‑compliance, especially while others comply, underlies much of the hesitancy in reaching international agreements on pollution strategies. Consideration and comparison of how both deontological and utilitarian approaches to ethics address this issue may make for interesting debate. In addition, the role of international legislation compared to increasing public awareness in tackling the problem could arguably be seen as a directly parallel debate. That is, is a system of rules, or appealing to the general good, the most effective way forward?


A fun, engaging and relevant programme, inspiring the viewer to consider the science within and how scientific process can be used to test ideas and develop theories, rather than just looking for a given answer to a known question.

Acid Rain And The Destruction On Canada
Author Unknown

    ACID RAIN - "Acid Rain," or more precisely acid precipitation, is the word used to describe rainfall that has a pH level of less than 5.6. This form of air pollution is currently a subject of great controversy because of it's worldwide environmental damages. For the last ten years, this phenomenon has brought destruction to thousands of lakes and streams in the United States, Canada, and parts of Europe. Acid rain is formed when oxides of nitrogen and sulfite combine with moisture in the atmosphere to make nitric and sulfuric acids. These acids can be carried away far from its origin.

    The two primary sources of acid rain are sulfur dioxide (SO2), and oxides of nitrogen (NOx). Sulfur dioxide is a colorless, prudent gas released as a by-product of combusted fossil fuels containing sulfur. A variety of industrial processes, such as the production of iron and steel, utility factories, and crude oil processing produce this gas. In iron and steel production, the smelting of metal sulfate ore, produces pure metal. This causes the release of sulfur dioxide. Metals such as zinc, nickel, and copper are commonly obtained by this process. Sulfur dioxide can also be emitted into the atmosphere by natural disasters or means. This ten percent of all sulfur dioxide emission comes from volcanoes, sea spray, plankton, and rotting vegetation.

    The other chemical that is also chiefly responsible for the make-up of acid rain is nitrogen oxide. Oxides of nitrogen is a term used to describe any compound of nitrogen with any amount of oxygen atoms. Nitrogen monoxide and nitrogen dioxide are all oxides of nitrogen. These gases are by-products of firing processes of extreme high temperatures (automobiles, utility plants), and in chemical industries (fertilizer production). Natural processes such as bacterial action in soil, forest fires, volcanic action, and lightning make up five percent of nitrogen oxide emission.

    It has been estimated that acid rain causes $1 billion worth of damage in Canada every year. Thousands of lakes have been damaged; a large part of the salmon habitat in the Maritimes has been lost; a significant proportion of eastern Canada's forests has been affected; and considerable damage to buildings and monuments has been documented. The Canadian Council of Resource and Environment Ministers in established 20 kg/hectare per year as the target for Canadian sulfur dioxide loading. In eastern Canada, 96% of the land with high capability for forestry is subject to acidic deposition in excess of 20 kg/ha per year. In recent years, important instances of dieback and declines in growth rate have been noted in sugar maple groves in parts of Canada that receive high levels of these and other air pollutants, such as ozone. Significant growth declines in northern Ontario forests, most notable over the past 30 years, coincide with a period of rapidly increasing industrialization and urbanization across much of the province.

    About 40% of nitrogen oxides come from transportation (cars, trucks, buses, trains), and 25% from thermoelectric generating stations, and the balance from other industrial, commercial, and residential combustion processes.

    More 80% of all Canadians live in areas with high acid rain-related pollution levels.

    Transportation makes up 43 percent, and 32 percent belongs to industrial combustion.

    The interactions between living organisms and the chemistry of their aquatic habitats are extremely complex. If the number of one species or group of species changes in response to acidification, then the ecosystem of the entire water body is likely to be affected through the predator-prey relationships of the food web. At first, the effects of acid deposition may be almost imperceptible, but as acidity increases, more and more species of plants and animals decline or disappear.

    As the water pH approaches 6.0, crustaceans, insects, and some plankton species begin to disappear. As pH approaches 5.0, major changes in the makeup of the plankton community occur, less desirable species of mosses and plankton may begin to invade, and the progressive loss of some fish populations is likely, with the more highly valued species being generally the least tolerant of acidity.

    Below pH of 5.0, the water is largely devoid of fish, the bottom is covered with undecayed material, and the near shore areas may be dominated by mosses.

    Terrestrial animals dependent on aquatic ecosystems are also affected. Waterfowl, for example, depend on aquatic organisms for nourishment and nutrients. As these food sources are reduced or eliminated, the quality of habitat declines and the reproductive success of the birds is affected.

Acid-Rain in the forest and beyond.

By: Brittney McKenzie

    Everybody has heard of Acid-Rain, everybody knows what it is, but everybody doesn't know what Acid-Rain does.  Acid-Rain has effects that just doesn't effect one place in the forest but it effects most of the forest.  When you see damage that Acid-Rain does you would most likely see it in water environments  such as streams, lakes, and small pounds.  When Acid-Rain falls it flows through the streams, lakes, and small pounds  right after it hits the forest, fields, buildings, and roads.  But only sometimes Acid-Rain can fall directly in the water. When Acid-Rain falls more and more different types of fish and other aquatic plants and animals that live in theses waters decrease by the day... week... year.  Because Acid-Rain causes the loss of acid-sensitive plants and animals, and fish that rely on these organisms for food may also be affected.  So just by Acid-Rain falling into water that is some of the things that Acid-Rain can do but there is a lot more.  When Acid-Rain comes down it hits the plants and kills the plants being unable to grow back.  The soil will dry up and stay hard until it is watered if this continues then there will be no more plants on Earth and if there is no more plants on Earth then all humans will die because plants have air and without air people will die.  Acid-Rain can effect not only water and water environments but it can effect land.  Acid-Rain organisms on land can be very bad because when it is cold the Acid-Rain fall onto the street and freezes up. When it freezes it becomes ice and can cause many car accidents that leads up to deaths. When Acid-Rains falls it kills animals homes all at the same time leaving nothing but broken trees and hard soil. As a result of their homes being near the water environments their food that comes from the water will most likely to harder to get  because  the population would be decreasing. People help with Acid-Rain in away because we pollute the air with our cars and other things that give off gas and Acid-Rain pollutes the air as it come down so nature and humans are polluting the air. Acid- Rain do not effect just water environments and land but one of the serious side effects of acid rain on human is "respiratory" problems. The dioxide and nitrogen oxide emission gives risk to respiratory problems such as dry coughs, asthma, headaches, eye, nose, and throat irritation. Polluted rainfall is especially harmful to those who suffer from asthma or those who have a hard time breathing. But even healthy people can have their lungs damaged by acid air and rain. Acid rain can aggravate a person's ability to breathe and may increase disease which could lead to death. The United States provide a glimpse of such costs. That acid precipitation destroys, overall, $13,000 million annually in the eastern part of the nation and could cause $1,750 million yearly in forest damage, $8,300 million in crop damage in the Ohio River basin alone by about the year 2000 and $40 million in health costs in the State of Minnesota. The only cost-effective solution to the problem, according to many people, is to reduce emissions at their point of origin. Anyone investigating acid rain should update these figures.  In conclusion, all these things kills off the forest in so many different ways if it is not by Acid-Rain then it is by cars. When we do things we are killing our self. So Acid-Rain can kill things that we need so know everybody knows about what it and everybody has heard of it and everybody knows what it does now.





Acid Rain
By Robert Brown

What kind of destruction can/does acid rain cause?

    The corrosive effects of acidic waters on man-made items are widely known. On the other hand, we only can speak mostly in generalities when discussing the effects of acid-rain on natural environments. The short-term danger from acid rain is mostly to forest and lake ecosystems, which are very sensitive to chemical imbalances in their environment. With the loss of these ecosystems that effectively moderate the pH of surface run-off water in many areas, the effect of acid rain on local water supplies could become more pronounced in the future.

Where does the pollutant that forms acid rain come from? How is acid rain formed?

    Acid rain forms when molecules of oxidized sulfur and/or nitrogen in the atmosphere combine with water, forming acidic compounds that dissolve in the water that becomes rain. Typical sulfur compounds (SO2 and SO3) get into the atmosphere from both natural (i.e. volcanoes, windblown dust containing gypsum-which has SO4 ions in it, etc..) and non-natural (i.e., burning of coal, refining of metal ores) sources. Nitrogen compounds also get into the atmosphere and form acids, although the natural sources are much more limited. The biggest non-natural source is burning fossil fuels, especially gasoline.

  There are many problems and effects caused by acid rain. Acid rain can cause buildings, statues and bridges to deteriorate faster than usual. another problem is it harms thousands of lakes, rivers, and streams worldwide. It disrupts lake ecosystems and kill wildlife in affected lakes, rivers and streams. Acid rain also damages soil and the tree roots in it. When soil is acidified, tree roots are damaged, leaving them not able to draw in enough nutrients to support the tree. When acid rain falls on trees, it makes their leaves turn brownish-yellow and the tree can no longer carry out photosynthesis properly. Another problem is it will harm people when they breathe in smog, acid rain in one of its many forms. Acid rain can also harm people in-directly. This happens when people eat fish caught in affected lakes or rivers. Also, if the water source is acidic enough, it will react with copper or lead pipes to harm humans. It also washes aluminum into the water supply. Birds can be harmed if they live in affected waters or feed on fish living in affected waters.

This picture shows the total effects of a factory polluting the air through these steps:

1.) A factory by a lake releases smoke into the air
2.) Dry deposition from the smoke falls into the lake
3.) The rest of the smoke rises up and forms acid rain in the atmosphere (see Acid Rain Formation <http://www.angelfire.com/ks3/acidrainreport/formation2.html>)

4.) The wind causes the acid rain cloud to travel
5.) Acid rain falls on a forest and acid snow falls on a mountain 6.) After all this, the lake is affected, the river is affected, the soil is affected and the vegetation is affected

Conclusion on Acid Rain And Automobiles
Author Unknown   

    In conclusion, the two primary sources of acid rain is sulfur dioxide and nitrogen oxide.  Automobiles are the main source of nitrogen oxide emissions, and utility factories are the main source for sulfur dioxide emissions.  These gases evaporate into the atmosphere and then oxidized in clouds to form nitric or nitrous acid  and sulfuric acid.  When these acids fall back to the earth they do not cause damage to just the environment but also to human health.  Acid rain kills plant life and destroys life in lakes and ponds.  The pollutants in acid rain causes problem in human respiratory systems.  The pollutants attack humans indirectly through the foods they consumed.  They effected human health directly when humans inhale the pollutants.  Governments have passed laws to reduce emissions of sulfur dioxide and nitrogen oxide, but it is no use unless people start to work together in stopping the release of these pollutants.  If the acid rain destroys our environment, eventually it will destroy us as well.


Acid Rain And The Social Impact
Shaun Washburn 

     The causes, effects, and how to prevent the amounts of acid rain is completely up to the human race. The cause of acid rain is simple. It’s the humans and their constant quest for the cheapest most efficient way to do things. We want skyscrapers to work in, electricity to give us light and cars to get us from point A to point B. The gases such as sulfur dioxide, nitrogen monoxide, and nitrogen dioxide are created from the production of steel and iron, utility factories and crude oil processing. The smelting of metal sulfate ore produces pure metal. This causes the release of sulfur dioxide. Metals such as zinc, nickel and copper are obtained by this process. There is cost efficient ways to obtain these things and then there is cleaner ways which are better for our environment. Of course the manufacturers are going to want to use the less costly. Their greed and their constant quest to have more and more is what seems to be the first area of concern to them. One can only have so much, then what is there? I’ll tell you what there isn’t and that’s satisfaction. We the people really don’t need more than what we use. Yet there is constant over indulgence in our society. Give me more and more and don’t forget to give it to me for free. The problem lies within the consumer as much as it does the producer. No one is at more fault than the other.

     The affects that acid rain has on our lives is devastating and if we do not stop it, it will ultimately kill the human existence. Acid rain is accumulated in our clouds and in our atmosphere. It travels from place to place spreading its destruction across the land. The affects of acid rain aren’t immediate. It is more of a slow gradual process. Every year as the pH balances get worse we notice more effects the acid rain has. It affects our trees and plant life, our lakes and streams and the animals as well. The animals are affected by drinking the water that runs off the mountains and eating the plant life. We humans are affected by the depletion of the trees that gives us the necessary oxygen to breathe as well as the vegetation and animals we consume. Indirectly we are affected but we affect it directly and constantly everyday by our selfish wants, fictitious needs and our persistence in searching for efficiency.

     What we can do to stop our ever so obvious suicide we commit on a daily basis is quite simple to see. Find more environmentally friendly ways to exist and have our manufacturers understand it needs to be cost efficient. Solar energy and the development of different ways to harness it for our usage could possibly be an effective way to reduce the amounts of acid rain. Hybrid cars as well as the usage of natural gases, propane and hydrogen are also good suggestions to cut down on the amount of pollution that goes into our atmosphere. The manufacturers must remember it must be cost efficient or the consumer will not be able to survive. It’s either the demise of humanity or corporations understanding the cost of living for the low man on the totem pole. It would be nice if they could try to help humanity instead of themselves and their ten million dollar mansions surrounded by their thirty six, two hundred thousand dollar cars. These cars, may I add, probably emit the same gases that are causing the destruction of not only the environment but our civilization on planet Earth. Everyone must be in compliance and everyone must play their part. Those who have must give what they can and those who don’t must contribute what they are able to. Some have money, some have solutions while some can physically help, others can organize the possible ways and effective plans to solve this continuously growing problem that we constantly overlook. This cannot be done gradually. It must be done all at once. Every one of us holds an important piece to this world wide puzzle. In conclusion, people are the cause of acid rain, humans are affecting our planet in this negative way and only we can change this. It’s up to us not as individuals but as a whole.
