Finally, manufacturing plants can reduce the emissions that cause acid rain by using scrubbers to clean and remove the dangerous chemicals from the pipes before they are released into the air. Hubbard Brook Research Foundation - Links to reports and fact sheets on acid rain. Acid rain not only damages the plants but also it stops the growth of plants above the surface. Research shows that acid rain interferes with a fish’s ability to take in oxygen, salt, and nutrients. Acid rain runoff can also pick up aluminum from the soils and carry it into lakes and streams. 2. An official website of the United States government. Plants, soil, trees, buildings and even statues can be transformed by the precipitation.Acid rain has been found to be very hard on trees. Cornell University - Atmospheric Dust and Acid Rain, a presentation by Lars O. Hedin and Gene E. Likens. Runoff from acid rain leaches minerals such as aluminum from soil, thereby decreasing its pH and making the soil acidic. Effects of Acid Rain You wouldn't think a decrease from 5.6 to 4.4 would cause that many problems, but it does. Algae growth is increased by acid rain, and rock scaling microbial and invertebrate herbivores lose habitation and die. It weakens them by washing away the protective film on leaves, and it stunts growth. Over time, acid deposition, which includes acid rain, snow, and other kinds of acidic inputs, affects lakes and rivers. Over a period of time, acids get accumulated in the water and lower the overall pH of the water body. At pH 5, most fish eggs cannot hatch. Studies show an increase of chronic conditions, such as asthma and bronchitis, in people who are regularly exposed to acid rain. These effects seriously reduce the value to society of buildings, bridges, cultural objects (such as … The Effects of Air Pollution: Acid Rain. When acid rain falls upon an ecosystem, it affects the water supply as well as the plants and animals in that area. In addition, NOX emissions also contribute to ground level ozone, which is also harmful to human health. Acid rain describes sulfuric and nitric acids deposited from the atmosphere. If something harms one part of an ecosystem – one species of plant or animal, the soil or the water – it can have an impact on everything else. Rain contaminated by these compounds changes the pH of water and soil, making them more acidic. Acid rain is also affecting the flora of the environment, including the weak productivity of the forest area. This directly affects the mineral levels of the soil and the creatures, such as snails, that rely on that calcium for shell growth. Effects . When acid rain falls upon an ecosystem, it affects the water supply as well as the plants and animals in that area. The Adirondack Mountains proved especially susceptible. What Are the Effects of Acid Rain on the Environment? Gases produced from the burning of fuels react with the oxygen in the air and water vapour, transforming into acids that fall onto the earth's surface as rain. Everything in an ecosystem is connected. As the acidity of a lake increases, the water becomes clearer and the numbers of fish and other water animals decline. Conserving energy is the number one way humans can prevent acid rain. Some types of plants and animals are able to tolerate acidic waters and moderate amounts of aluminum. Environment Canada - Frequently asked questions about acid rain. At high elevations, acidic fog and clouds might strip nutrients from trees’ foliage, leaving them with brown or dead leaves and needles. C… The term acid rain was coined in the late 1800s. The experimental procedure consists of the following steps. Acid rain is dangerous to humans. Environmental Protection Agency - Advice on how to reduce the production of acid rain. It removes it and other minerals and nutrients from the soil, as well. Washington University - An outline of the chemical composition of acid rain. Congress of the United States - Congressional Budget Office's 2008 Policy Options for Reducing CO2 Emissions. Public awareness of acid rain grew in the 1970s when published studies revealed damage to lakes caused many species of fish to disappear. It is believed that the acid rain causes the damage as it dries on, and evaporates from, the surface. Acid rain is one of the consequences of air pollution. When acid rain and dry acidic particles fall to earth, the nitric and sulfuric acid that make the particles acidic can land on statues, buildings, and other manmade structures, and damage their surfaces. Acid rain is also called acid deposition because this term includes other forms of acidic precipitation (such as snow). The anthropogenic causes of acid rain are associated with human action: Emissions by plants and factories of various oxides of nitrogen and sulfur. Certain industrial pollutants, however, can decrease the pH excessively, causing it to pose a danger to the environment. Elmhurst College - Virtual chemistry book on acid rain effects and solutions. As pH drops, aquatic life is negatively affected, especially molluscs and fish. The Encyclopedia of Earth - Dr. Gene E. Likens' presents a detailed report on acid rain. Sometimes dust particles can become acidic as well, and this is called dry deposition. The higher the degree of acidic concentration, the higher the outcomes can be disastrous. Acid rain makes such waters more acidic, which results in … Acid rain and the dry deposition of acidic particles contribute to the corrosion of metals (such as bronze) and the deterioration of paint and stone (such as marble and limestone). Generally, the young of most species are more sensitive to environmental conditions than adults. Acid rain leaches calcium out of the soil when it is absorbed by the earth. Before falling to the earth, acid-causing emissions (sulphur dioxide and nitrogen oxide gases and the related acid particles) contribute to haze and smog and affect public health. Effect on Aquatic Environment. Even if a species of fish or animal can tolerate moderately acidic water, the animals or plants it eats might not. In addition to agriculture and wastewater, much of the nitrogen produced by human activity that reaches coastal waters comes from the atmosphere. environmental effects of acid rain such as the acidi fi cation of sur- face waters and toxic effects on vegetation, fi sh, and other biota. Weakened plant life cannot tolerate extreme temperatures or fight off insects and disease. SUNY at Plattsburgh - Dr. Tom Wolosz presents a comprehensive report on the effects of acid rain. Sometimes dust particles can become acidic as well, and this is called dry deposition. Snow and fog can also contain nitric and sulfuric acid, and the dangerous effects are the same whether the acid is falling to the earth by rain or snow, or dancing in the air via fog. Acid rain can affect drastically the ecosystem, aquatic and terrestrial biota. That aluminum may be harmful to plants as well as animals. Environmentalists divide them into man-made and natural. 1. United States Geological Survey - The USGS' Water Science for Schools page on acid rain. 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. When acid rain a… Auto and paint coating manufacturers are trying to develop protective coatings that prevent acid rain corrosion. National Geographic - National Geographic reports on the causes of acid rain. As it alters the chemical composition of the water, to a form which is actually harmful to the aquatic ecosystem to survive and causes water pollution. 6 Critical of Acid Rain Acid rain influences soil chemistry, plant activities, and the acidity of surface waters in general. 2. Princeton University - Environmental effects of particulate matter. Not all acidic deposition is wet. Walking in acid rain, or even swimming in a lake affected by acid rain, is no more dangerous to humans than walking in normal rain or swimming in non-acidic lakes. These gases mix with water vapor in the air and react to form acidic compounds, which fall to earth as rain or snow, sometimes hundreds of miles from their source. “Science identified the problem. Melting snow and heavy rain downpours can result in what is known as episodic acidification. Acid Rain Damages Buildings and Objects Acid rain can also have a damaging effect on many objects, including buildings, statues, monuments, and cars. Decreased calcium also creates excess aluminum in the soil, preventing trees and other plant life from absorbing water. For optimum growth, many plants have a specific pH level and acid rain varies that number affecting the growth. Acid rain directly affects the chemical and pH balances in ground water. Animals that cannot withstand the chemical imbalances die, fail to reproduce, become deformed due to bone decalcification, or fail to grow normally. The consequences of this damage can be costly: In the atmosphere, SO2 and NOX gases can be transformed into sulfate and nitrate particles, while some NOX can also react with other pollutants to form ozone. The more acid that is introduced to the ecosystem, the more aluminum is released. Naturally acid rain has always been involved in the weathering of rocks at the earth's surface. Terrestrial ecosystems take much longer to show the effects of acid rain than aquatic ecosystems. Acid rain … After studying the Hubbard Brook Forest and other areas, researchers found several important effects of acid deposition on both natural and man-made environments.
