HECS Home Safe Environments What's New Welcome ... Summaries ACID RAIN Air pollution from the burning of fossil fuels is the major cause of acid rain.  Acid rain is the popular name for precipitation acidified by atmosphere pollutants.  Acid rain is caused by pollutants such as nitrogen oxides (NOx) and sulphur dioxide (SO ), which in the atmosphere are converted chemically to nitric acid and sulphuric acid.  Diluted forms of these two acids fall to earth as rain, or snow. More than 90% of the NOx and SO emissions occuring in North America are due to human activities.  Acidic pollutants may be transported over great distances by winds and weather systems.  It is estimated that more than 50% of the acid rain falling in Southern Ontario and the Atlantic region come from U.S. sources. Acid rain can affect lakes, forests, materials such as buildings and cars and human health.  The health concerns related to acid rain are derived primarily from the precursors SO and NOx.  In the air SO can react with water and other chemicals to form very fine particles.  NOx is a precursor of ozone and particles.

Acid Rain What is Acid Rain? Acid rain is a result of air pollution. When any type of fuel is burnt, lots of different chemicals are produced. The smoke that comes from a fire or the fumes that come out of a car exhaust don't just contain the sooty grey particles that you can see - they also contains lots of invisible gases that can be even more harmful to our environment. Power stations, factories and cars all burn fuels and therefore they all produce polluting gases. Some of these gases (especially nitrogen oxides and sulphur dioxide) react with the tiny droplets of water in clouds to form sulphuric and nitric acids. The rain from these clouds then falls as very weak acid - which is why it is known as "acid rain". How acidic is acid rain?

Acid Rain Written by Colin Hocking, Jacqueline Barber, and Jan Coonrod This stimulating unit fosters scientific inquiry and critical thinking skills as it harnesses the curiosity, agility, and determination of student minds to study the troubling environmental issue of acid rain. Students learn about acids, bases, and the pH scale; make "fake lakes" and determine how their pH changes after an acid rainstorm; present a play on the effects of acid rain on aquatic life; determine the effect of various dilutions of acid on seed germination; and hold a town meeting to discuss possible solutions to the problem of acid rain. A "startling statements" game challenges students' preconceptions and prompts investigation. In addition to providing much information on acid rain, the unit encourages students to analyze complex environmental issues for themselves, and emphasizes community cooperation (making it an effective companion unit to the GEMS guide Time: Eight or more 45- to 60-minute sessions.

Acid Rain Simulation Louie Beuschlein YES! I'd like to download the original onto Microsoft Word 6.0 or higher. Introduction : This is a two day unit plan that incorporates some decision-making ideas from statistics into the science classroom. It is intended for intermediate level science students (about high school freshman age) and beyond. No previous experience with statistical analysis is required. The NCTM Statistics Standard is taken into account in this lesson by having students make use of sampling to back up a claim and by having students design (with teacher assistance) a statistical experiment to study a problem. Acid Rain Lab : Acid rain is literally acid in rain water. It is a weak acid (sulfuric and nitric) but strong enough to damage buildings and statues and harm lakes, forests, and crops. The purpose of this lab is to investigate the damaging effects of acid rain on plants. In particular, students will determine whether and/or to what extent acid rain affects the germination rate of turnip seeds. The germination rates of seeds placed in an acid rain solution will be compared with that of the controlseeds placed in distilled water. Statistical methods will then be employed to determine whether any differences in germination rates is attributable to the acid rain or if it is reasonable to explain any differences as coincidences. The acid rain solution should be a mixture of dilute sulfuric and nitric acids (about pH 4). Students, working in groups of no more than four, should sandwich exactly 25 turnip seeds (or some other type of seed) between two layers of paper toweling saturated in acid rain solution. (There should be no pools of solution.) Each group should also prepare a control Petri dish in which distilled water is used in place of the acid rain solution. The Petri dishes should then be wrapped in aluminum foil to keep them in darkness and allowed to remain undisturbed (preferably for a weekend).

It causes fish and plants to die in our waters. As well it causes harm to our own race as well, because we eat these fish, drink this water and eat these plants. It is a problem that we must all face together and try to get rid of. However acid rain on it's own is not the biggest problem. It cause many other problems such as aluminum poisoning. Acid Rain is deadly. WHAT IS ACID RAIN? Main source of acid rain is sulfur dioxide and nitrogen oxides in the atmosphere. Power plants are a major source for sulfur dioxide and as well nitrogen oxide. Automobiles, trucks and buses are major contributors of nitrogen oxides in urban and suburban environments. Acid rain is all the rain, snow, mist etc that falls from the sky onto our planet that contains an unnatural acidic. It is not to be confused with uncontaminated rain that falls, for that rain is naturally slightly acidic. It is caused by today's industry. When products are

The student shall be given opportunities to (B) observe properties and patterns of objects, organisms and events in the environment. (4) Communicate data and information in appropriate oral and written form. The student shall be given opportunities to (B) describe objects, organisms and events from the environment, (D) describe changes that occur to objects and organisms in the environment. Objective: Students will learn how acid rain is an air pollution problem. Focus: Show a picture of a defaced statue. Materials: chalk, vinegar and glasses for each group Background: Acid rain is more acidic than normal rain and forms through a complex process of chemical reactions involving air pollution. The two most important pollutants that contribute to the formation of acid rain are oxides of nitrogen and sulfur dioxide, which react with moisture in the atmosphere to form nitric and sulfuric acid. The sulfur and nitrogen compounds that contribute to acid rain primarily come from manmade sources, such as industries and utilities. Emissions also come from automobiles and other forms of transportation and industrial processes, such as smelting. Acid rain can harm forests and crops, damage bodies of water, and contribute to the damage of statues and buildings. Researchers are considering the possible effects of acid rain on human heath. These acidic pollutants can be deposited through rain, snow, fog, dew, or sleet. Large quantities can also be deposited in a dry form through dust.

Peggy travels to the Wolf Ridge Environmental Learning Center to learn about acid rain. ACID RAIN What causes acid rain? How does acid rain damage the environment? Is acid rain harmful to people? How does the acid get in the rain? Is there any way to stop the damage it causes? DISCUSSION Acid rain is considered by many people to be one of the most serious environmental problems of our time. It is a global problem that is gradually affecting our world. The term acid rain was coined by Angus Smith when he wrote about industrial pollution in England. Some rain is naturally acidic because of the carbon dioxide (CO2) in air that dissolves with rain water and forms a weak acid. This kind of acid in rain is actually beneficial because it helps dissolves minerals in the soil that both plants and animals need. Recently there has been some concern that the acidity of rain caused by man has increased over the last several decades. Acid rain attacks wildlife, crops and lakes. It can cause the death of forests and damage buildings and monuments. It is even harmful for human beings.

The Global Commons Acid Rain: Downpour in Asia? Overview SO Emissions in Asia Could Triple More to Do in the Developed World ... Levels are Stilll A Problem in Europe and North America Overview Although there has been major progress in controlling acid-forming emissions in some countries, the global threat from acid rain is far from over yet. In fact, the dimensions of the acid rain problem are growing rapidly in Asia, with sulfur dioxide (SO ) emissions expected to as much as triple from 1990 levels by 2010 if current trends continue. Curtailing the already substantial acid rain damage in Asia and avoiding much heavier damages in the future will require investments in pollution control on the order of those made in Europe and North America over the past 20 years Even in developed countries where there have been serious efforts to control acid rain, the story is more complicated than it once appeared. Questions remain in regards to how much damage has been done to forests, lakes, and streams over the years; whether current progress is sufficient to protect the most vulnerable ecosystems; and how soon acid-damaged areas will recover. Acid rain emerged as a concern in the 1960s with observations of dying lakes and forest damage in northern Europe, the United States, and Canada. It was one of the first environmental issues to demonstrate a large-scale regional scope, with the chief pollutants oxides of sulfur (SO

Frey at gfrey@wuchem.wustl.edu Natural Acidity of Rainwater Pure water has a pH of 7.0 (neutral); however, natural, unpolluted rainwater actually has a pH of about 5.6 (acidic).[Recall from Experiment 1 that pH is a measure of the hydrogen ion (H ) concentration.] The acidity of rainwater comes from the natural presence of three substances (CO , NO, and SO ) found in the troposphere (the lowest layer of the atmosphere). As is seen in Table I, carbon dioxide (CO ) is present in the greatest concentration and therefore contributes the most to the natural acidity of rainwater.

Acid Rain Acid rain is a general name for many phenomena including acid fog, acid sleet, and acid snow. Although we associate the acid threat with rainy days, acid deposition occurs all the time, even on sunny days. Acid Deposition is the scientific term used to describe "Acid Rain". When atmospheric pollutants such as sulfur dioxide and nitrogen oxides mix with water vapor in the air, they are converted to sulfuric and nitric acids. These acids make the rain acidic, hence the term "acid rain". Rain returns the sulfur and nitrogen acids to Earth, and in high concentrations, can cause damage to natural environments including forests and freshwater lakes. This form of acid deposition is known as wet deposition. Average measured acidity in precipitations (USA) recorded for 1999 ( reference

Home About Us For Teachers For Students ... More Below! Acid Rain What is it? Acid rain is a term which you may have heard, but not quite understood. It certainly sounds very nasty doesn't it? But, unlike in cartoons, acid rain does not burn through everything that it touches! It does cause a lot of damage to buildings, plants, animals, and even humans, however. It is also a bit misleading, because even pure rainwater is slightly acidic. 'Acid rain' just means that the rain is more acidic than it should be. Before we look at what damage acid rain actually does, it is best to look at why it happens. How acid rain is formed The main elements which are responsible for acid rain, are sulphur and nitrogen (in gas form). Both of these can be caused by a number of things, including some human activities, but they are also made naturally. Human activities which produce sulphur dioxide and nitrous oxides include burning fossil fuels (like coal, and crude oil). Two things that are highly responsible for causing acid rain are power stations and factories. Although these are essential to human life in this day and age, they make large amounts of sulphur dioxide and nitrous oxides. In fact, power stations produce 70% of all of the chemicals which are responsible for acid rain.

Acid Rain in the Year 2000 The most productive time to fly fish was just before sundown as the evening shadows lengthened across the remote Adirondack lake. As soon as the May Fly hatch began the native brook trout started a hearty feeding frenzy. There would be trout for breakfast..... But all this was twenty years ago. Today the native brook trout are gone and May Fly hatches are sparse. Genetically altered trout have been introduced - trout that can survive acidic water but cannot reproduce. The coniferous/deciduous forest surrounding the small lake is also in sharp decline. Acid rain has killed most of the red spruce and great stands of hardwoods are heavily diseased and dying. Professional foresters explain that acid deposition has compromised the nutritional intake of the trees, which diminishes their ability to fight natural diseases. Fifteen years ago we would "timbercruise" looking for culls to fuel our fireplaces. Today we simply take trees that have fallen a short distance from our cottages. Because airborne pollutants fall to the earth in dry form as well as liquid, the term acid rain is somewhat misleading -hence the term acid deposition. This is an important distinction as many believe that acidic fallout occurs only during periods of rain or snow, whereas it is actually a constant event.

The principal natural phenomena that contribute acid-producing gases to the atmosphere are emissions from volcanoes and from biological processes that occur on the land, in wetlands, and in the oceans. The effects of acidic deposits have been detected in glacial ice thousands of years old in remote parts of the globe. Principal human sources are industrial and power-generating plants and transportation vehicles. The gases may be carried hundreds of miles in the atmosphere before they are converted to acids and deposited. Industrial acid rain is a substantial problem in China Eastern Europe Russia and areas down-wind from them. These areas all burn sulfur-containing coal to generate heat and electricity. Acid rain is defined as rain with a pH of below 4.0 - 4.5. Normal rain has a pH of about 5.6, which is slightly acidic. This natural acidity is caused by dissolved carbon dioxide dissociating to form weak carbonic acid . 'Acid rain' is caused by sulfur from impurities in fossil fuels and nitrogen from the air combining with oxygen to form sulfur and nitrogen dioxides. These diffuse into the atmosphere and react with water to form
