Acid Deposition Acid deposition is a widespread problem found all over the world. Since the

Acidity of an ecosystem, measured in pH, is a crucial factor to the survival of a species in an ecosystem. Altering it can have result in dramatically negative effects, in spite of the fact that pH of an ecosystem has been dramatically changed over a relatively short period of time due to various human activities. For example, acid rain is a major environmental problem that is caused by human-made pollution. When fossil fuels are burnt to get energy, pollutants like sulfur dioxide and nitrogen oxides get mixed into the rainwater and eventually are evaporated into the atmosphere. These gases enter the atmosphere, and mix with water in the water cycle to form an acidic mixture of water and gases. This water falls in the form of acid rain, which

Atmospheric deposition is the process, long recognized by scientists, whereby precipitation (rain, snow, fog), particles, aerosols, and gases move from the atmosphere to the earth's surface. Materials reaching the earth in precipitation or as dry deposition originate from a variety of air pollution sources and can be harmful to the environment and public health. Acidic deposition is the most widely acknowledged form of atmospheric deposition, with well-known effects on lakes, streams, and forests. More recently, atmospheric contributions of nutrients have received increasing attention, particularly as a source of excessive nitrogen entering the Chesapeake Bay. In addition, atmospheric deposition may be a significant source of environmental

Acid deposition can come in two forms, dry and wet. Wet deposition is when the acid falls in the form of fog, snow or other precipitation. Dry deposition is found in dry areas where it does not precipitate often. In these areas the chemicals fall as dust or smoke, and stick to whatever they land on. Acid deposition can be result to both natural and manmade sources. Natural sources of acid deposition include electrical storms, volcanoes, and decaying vegetation. Man-made emissions, from power plants that burn fossil fuels are released into the atmosphere as nitrogen oxides (NOx), and sulfur dioxide (SO2). These elements react to oxygen, water, and other gasses in the atmosphere in order to form acidic compounds. These acidic compounds then fall in either a wet or dry form. Acid rain can have a potentially devastating effects on the ecosystem it falls on. When acid rain hits the ground, it faces a natural buffer in the soil often in the form of limestone and calcium carbonate. The water will then travel into either a stream or a lake, where it affects fish. If the fallen rain has a pH at or below 5 undesirable species invade, often in the form of mosses or plankton. The top layer of water becomes too acidic for the inhabitants reproductive cycle to work properly, slowly killing off the

Problems include; land degradation, air pollution, water pollution and loss of biodiversity. These harmful impacts to the environment need to be addressed with urgency (Djekic and Tomasevic, 2016).

Acid deposition effects water systems because it lowers the pH in the water, creating adverse effects. More Acidic water will also more readily absorb aluminum leached from soil runoff. The combination of aluminum and acidic water is very harmful to many species. When biomagnification occurs many species will die off resulting in less biodiversity in the water system. Dead or dying trees is a common sight with acid deposition in effect. Acid rain leaches aluminum from the soil, doing so sucking the nutrients from the tree and causing death. At high elevation acidic fog, or clouds can strip the nutrients from the trees foliage’ causing them to lose leaves and die. The trees are also less able to absorb sunlight, and with that will not be able to achieve photosynthesis. As well as rural areas, urban areas also get affected. If buildings are made out of marble or limestone, the stone will begin to peel and chip away over time. This is possible because when the main crust chips away underneath is something composed of gypsum. A mineral that forms from the reaction between calcite, water, and sulfuric acid. This mineral can be slowly eaten away and destroyed by acid

Acid precipitation is a wide term that incorporates any type of precipitation with acidic parts, for example, sulfuric or nitric acid that tumble to the ground from the climate in wet or dry structures. This can incorporate into rain, snow, haze, hail or even clean that is acidic. Acid rain as numerous natural impacts, yet none is more prominent than its effect on lakes, streams, wetlands, and other amphibian situations.

Acid rain is rain that has been made acidic by certain pollutants in the air and has low pH levels that can harm the environment. It is a type of acid deposition that can appear in many forms such as, wet deposition, which can be rain, sleet snow or fog that is more acidic than normal, and dry deposition, where gases and dust particles become acidic. (Epa.gov) Acid deposition in wet and dry forms, falls on buildings, cars and trees and makes lakes acidic, which then leads to the danger of plant and animal life. Dry acid deposition though, can be inhaled by humans, which can then cause health problems. (Epa.gov)

It is caused by pollutants in the water, when sulfur dioxide and nitrogen oxides combine in the atmosphere. Sulfur dioxide is formed by coal burning power plants and nitrogen oxides are made by car exhaust (1).The precipitation of acid rain occurs in the sulfur cycle, nitrogen cycle, and the carbon cycle. Acid rain can be harmful to plants, animals, can pollutes rivers and streams, and destroys statues and buildings. Acid rain can suck the nutrients out of plants, or release a toxic substance into plant roots. The problem being investigated in this experiment how much acid rain affected building materials.

Through the advancement of technology, the issue of the air surrounding the earth might have been one of the most often matters to be brought up and discussed among scientists and engineers. Acid rain is one of the more serious environmental problems and it is closely related to the air pollution. Nowadays, it has affected large part of US, Europe and Canada. People start to be concerned about acid rain since it is getting worse in the passed years. The effect of the acid rain most often leads to another bad effect. For example, the acid rain will cause the lake and streams to be acidic. Thus, it will also affect the ecosystem inside the water.

Acid rain has a large concentration of hydrogen ions mainly coming from the burning of fossil fuels like coal, oil, and gas. It could kill living organisms, damage buildings, and monuments.

Another form of industrial waste that contributes to water pollution is acid rain. Acid rain is a product of industries burning coal. The burning of coal produces sulfur oxide and nitrogen oxide, and when these chemicals combine with the earth’s atmosphere it forms acid rain The Northeastern part of the United States has the worst acid rain levels in the world. More specific, the states with the highest concentration are Ohio, Indiana, Illinois, and some boarding parts of Canada and New England area. The falling acid rain can destroy plants and animals in several different ways. The acidification of a lake, river, or stream because of the high acidic levels in the water kills algae. Since algae are the main source of food, for many species of fish, they will also suffer from the high acid levels.

Acid rains as a phenomenon has been identified during the 19th century in Europe, and was attributed the smokes rising from chimneys factories coinciding with the overtime increase of rain acidification especially in Scandinavia. There is a growing interest in acid rains and its destructive effects in the light of the development of global industry especially in the industrialized countries, which consume huge quantities of fuel and release increasing quantities of gases such as sulphur dioxide, hydrogen, and nitrogen oxides which produce sulfur and nitrogenouns acids upon the interactions with oxygen and water vapour. Acids produced remain in the form of fine mist until dissolved in rainfall once occurs and then precipitates as

Acid rain affects thousands of people worldwide and is produced by factories and car fumes. It is the product of humanity and should not happen if we were careful of our carbon emissions. This phenomenon has contributed to many ruined water sources around the world. If acid rain was never a problem then places like Canada would have more forests and trees in Ontario. Also not as much coral would be dying in the ocean. Acid rain is a serious problem that needs to be addressed with caution and must be effectively dealt with before it is too

only harm the environment, but humans as well. Many studies have shown that people get toxic

Acid rain has proved to take a huge toll on Ontario’s ecosystem. However, in this section of the textbook, factors such as effects of acid rain, assessing the effects on soil and water, acidity levels and others, contribute to the main topic of acid rain in an ecosystem. To begin, the downpour of acid rain is due to the emissions from human activities that contain different pollutants/invisible gases that can be very harmful to the environment. In other words, substances containing nitrogen and Sulphur are released into the atmosphere from factories, industries, transportation and so on, where it then goes through a chemical transformation (nitric and sulphuric acid) where it either has a dry fallout, or condensation occurs and the acid descends
