It’s estimated that in Germany and Poland, half of the forests are damaged, while 30 percent in Switzerland have been affected. | Contact Us. The major natural causal agent for acid rain is volcanic emissions. When the pH level of rainwater falls below this range, it becomes acid rain. Apart from this, the burning of fossil fuels, the running of factories and automobiles due to human activities are a few other reasons behind this activity. It removes acid from the atmosphere and deposits them on the earth’s surface. Besides fossil fuels, there is a wide range of alternative energy sources that can generate electrical power. Are Landfills Bad for The Environment? pollutants, known as acid rain. Natural causes of acid rain are relatively small compared to those from anthropogenic sources as discussed above. High soil acidity also denatures enzymes for the soil microbes. Washing coal, use of coal comprised of low sulfur, and use of devices known as “scrubbers” can provide a technical solutions to SO2 emissions. What Is the pH of Water, and Why Does It Matter? Nature depends on balance, and although some rain is naturally acidic, These stick to the ground and other surfaces such as cars, houses, trees and buildings. in geography and a Certificate of Advanced Study in Geographic information Systems (GIS). Founded Conserve Energy Future with the sole motto of providing helpful information related to our rapidly depleting environment. Both natural and man-made sources are known to play a role in the formation of acid rain. (And Creative Ways to Reuse). After studying the Hubbard Brook Forest and other areas, researchers found several important effects of acid deposition on both natural and man-made environments. Even though dry, this form of deposition is dangerous as well, because precipitation can eventually wash pollutants into streams, lakes, and rivers. Both are discussed below: When the wind blows the acidic chemicals in the air to the areas where the weather is wet, the acids fall to the ground in the form of rain, sleet, fog, snow or mist. Mitigation of this challenge requires individuals to be more informed about energy conservation and ways of reducing emissions such as: turning off lights or electrical appliances when not using them; use public transport; use energy-efficient electrical appliances; and use of hybrid vehicles or those with low NOx emissions. Almost 50% of the acidic pollutants in the atmosphere fall back through dry deposition. bedrock, lakes, and streams. Power plants release the majority of sulfur dioxide and much of the nitrogen oxides when they burn fossil fuels, such as coal, to produce electricity. Acid deposition can be caused by natural sources such as volcanoes, but it is mainly caused by the release of sulfur dioxide and nitrogen oxide during fossil fuel combustion. Acid rain has significant effects on the world environment and public health. In addition, some amount of acid deposition is found in parts of South Asia, South Africa, Sri Lanka, and Southern India. i.e. Acid rain is made up of water droplets that are unusually acidic because of atmospheric pollution, most notably the excessive amounts of sulfur and nitrogen released by cars and industrial processes. (And Uses of Old Egg Cartons), 15 Sustainable and Green Building Construction Materials. Acid rain generally leads to weathering of buildings, corrosion of metals, and peeling of paints on surfaces. (And Ways To Dispose of), Can You Recycle Medicine Bottles? Over a period of time, acids get accumulated in the water and lower the overall pH of the water body. Howvever, over time, acids can accrue and lower the overall pH of the body of water. Over time, these neutralizing Although it was discovered in the 1800s, acid deposition did not gain significant public attention until the 1960s, and the term "acid rain" was coined in 1972. When acid rains seep into the soil, it means higher soil pH, which damages or reverses soil biological and chemical activities. Acidic deposition occurs in two ways: wet and dry. Finally, acid deposition also has an effect on architecture and art because of its ability to corrode certain materials. However, the dry depositions also known as gaseous particulates in the air which in this case are nitrogen oxides and sulfur dioxide can cause serious health problems when inhaled. Most of the electric power supporting the modern-day energy requirements comes from combusting fossil fuels such as oil, natural gas, and coal that generate nitrogen oxides (NOx) and sulfur dioxide (SO2) as the chief contributors to acid rain. By using ThoughtCo, you accept our, How the Sixth Mass Extinction Affects the U.S. Economy, Definition and Examples of Acid-Base Indicator. When these gases react with water molecules and oxygen among other chemicals found in the atmosphere, mild acidic chemical compounds such as sulfuric and nitric acid are formed resulting to acid rain. In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. Improvement of gasoline that combusts cleaner is also a strategy for reducing the emission of NOx gases. Volcanoes emit acid-producing gases to create higher than normal amounts of acid rain or any other form of precipitation such as fog and snow to an extent of affecting vegetation cover and health of residents within the surrounding. There are two forms in which acid deposition occurs – wet and dry. Erupting volcanoes contains some chemicals that can cause acid rain. What Causes Acid Rain? The term was coined in 1972 when the NY Times published reports about the climate change effects which started arising due to the occurrence of acid rain in the Hubbard Brook Experimental Forest in New Hampshire. ), Are Balloons Recyclable? rivers, and animals can result. Amanda Briney is a professional geographer. have made it worse. the two Acid rain runoff from catchment areas into rivers and lakes has also reduced biodiversity as rivers and lakes become more acidic. When this acid flows through the ground, it affects a large number of plants, animals and aquatic life. The activities include air pollution sources emitting sulfur and nitrogen gases like factories, power generation facilities, and automobiles. As acid lands on buildings (especially those constructed with limestone), it reacts with minerals in the stones, sometimes causing them to disintegrate and wash away. 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. materials can be washed away by acid rain. Catalytic converters are fixed on the exhaust pipe system to reduce NOx emission. Even though, liming is an expensive method and has to be done repeatedly. Acid rain is also called acid deposition because this term includes other forms of acidic precipitation (such as snow). Over the past few decades, humans have released so many different chemicals into the air that they have changed the mix of gases in the atmosphere. These substances But, it is mainly caused by the combustion of fossil fuels which results in emissions of sulfur dioxide (SO 2) and nitrogen oxides (NO x). “Scrubbing” also called flue-gas desulfurization (FGD) typically works to chemically eliminate SO2 from the gases leaving smokestacks. Normal precipitation—such Today, acid deposition is present in the northeastern United States, southeastern Canada, and much of Europe, including portions of Sweden, Norway, and Germany. Buildings and structures made of marble and limestone are the ones especially damaged by acid rain due to the reactivity of the acids in the rain and the calcium compounds in the structures. Species including fish, plant and insect types in some lakes, rivers and brooks have been reduced and some even completely eliminated owing to excess acid rain flowing into the waters. These gases react in the atmosphere with water, oxygen, and other chemicals to form various acidic compounds such as sulfuric acid, ammonium nitrate, and nitric acid. Both natural and man-made sources are known to play a role in the formation of acid rain. Adding lime into acidic surface waters balances the acidity. (And 3 Clever Ways to Dispose of Old Legos), Are Latex Gloves Recyclable? Acid rain also corrodes metals like steel, bronze, copper, and iron. These methods are simply called emission reduction strategies. Acid deposition is anything below that range. Decaying vegetation, wildfires and biological processes within the environment also generate acid rain forming gases. Individual, National/State, and International Actions, people can do to repair the damage caused, solution at the expense of solving the broader challenges, Are Legos Recyclable? Most notably, many governments are now requiring energy producers to clean smokestacks with scrubbers that trap pollutants before they are released into the atmosphere and to reduce car emissions with catalytic converters.
