Acid Rain Prevention This article on acid rain prevention gives its readers different tips regarding acid rain and how to prevent it from damaging natural and human life on earth. HelpSaveNature Staff Acid rain is a very serious environmental threat faced by our planet today. Millions of people get affected by it on a daily basis.
Simply put, it means rain that is acidic in nature due to the presence of certain pollutants in the air due to cars and industrial processes. It is easily defined as rain, fog, sleet or snow that has been made acidic by pollutants in the air as a result of fossil fuel and industrial combustions that mostly emits Nitrogen Oxides NOx and Sulfur Dioxide SO2.
Acidity is determined on the basis of the pH level of the water droplets. Normal rain water is slightly acidic with a pH range of 5. When the pH level of rain water falls below this range, it becomes acid rain. 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.
Acid rain generally leads to weathering of buildings, corrosion of metals, and peeling of paints on surfaces. Erupting volcanoes contains some chemicals that can cause acid rain.
Presently, large amounts of acid deposition is witnessed in the southeastern Canada, northeastern United States and most of Europe, including portions of Sweden, Norway, and Germany. Forms of Acid Rain There are two forms in which acid deposition occurs — wet and dry.
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. When this acid flows through the ground, it affects large number of plants, animals and aquatic life.
The water from drain flows into rivers and canals which is them mixed up with sea water, thereby affecting marine habitats.
If the wind blows the acidic chemicals in the air to the areas where the weather is dry, the acidic pollutants slip into dust or smoke and fall to the ground as dry particles.
These stick to the ground and other surfaces such as cars, houses, trees and buildings. These acidic pollutants can be washed away from earth surface by rainstorms. It was discovered way back in s during the Industrial Revolution. A Scottish chemist, Robert Angus Smith, was first to discover this phenomenon in as a relationship between acid rain and atmospheric pollution in Manchester, England.
But it gained public attention mainly in s. The term was coined in 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.
Causes of Acid Rain Both natural and man-made sources are known to play a role in the formation of acid rain. But, it is mainly caused by combustion of fossil fuels which results in emissions of sulfur dioxide SO2 and nitrogen oxides NOx.
Natural Sources The major natural causal agent for acid rain is volcanic emissions. 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.
Decaying vegetation, wildfires and biological processes within the environment also generate the acid rain forming gases. Dimethly sulfide is a typical example of a major biological contributor to sulfur containing elements into the atmosphere. Lighting strikes also naturally produces nitric oxides that react with water molecules via electrical activity to produce nitric acid, thereby forming acid rain.
Man-made sources Human activities leading to chemical gas emissions such as sulfur and nitrogen are the primary contributors to acid rain. The activities include air pollution sources emitting sulfur and nitrogen gases like factories, power generations facilities, and automobiles.
In particular, use of coal for electrical power generation is the biggest contributor to gaseous emissions leading to acid rain.
Automobiles and factories also release high scores of gaseous emissions on daily basis into the air, especially in highly industrialized areas and urban regions with large numbers of car traffic.
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. As a result, these areas experience exceedingly high amounts of acid rain. The existing winds blow these acidic compounds over large areas across borders and they fall back to the ground in the form of acid rain or other forms of precipitation.
Upon reaching the earthit flows across the surface, absorbs into the soil and enters into lakes and rivers and finally gets mixed up with sea water. Effects of Acid Rain Acid rain has significant effects on the world environment and public health.
Effect on Aquatic Environment: Acid rain either falls directly on aquatic bodies or gets run off the forests, roads and fields to flow into streams, rivers and lakes.
Over a period of time, acids get accumulated in the water and lower the overall pH of the water body.Acid rain falls to the earth like normal rainfall, but instead of nourishing the earth in the way that natural rainfall does, acid rain: has very negative effects on fish, plants, humans, and animals, can poison lakes, wells, and drinking water, erodes buildings, pavements, .
Sep 03, · Phytic acid is one of a number of “anti-nutrients” in grains and legumes.
For an introduction to this subject, please see this article. Proper preparation of whole grains [ ]. How to Take Action to Reduce Acid Rain. Acid rain, which is more accurately called acid deposition, refers to wet and dry atmospheric deposits that contain higher levels of acid than normal, and it can include wet precipitation like rain.
Precipitation (rain, vapours) mixed with acidic chemicals of the atmosphere lower the pH of rainwater and thus cause acid rain. Acid rain is hazardous for the life on the earth. ADVERTISEMENTS: Essay on Air Pollution: Causes, Effects and Control of Air Pollution!
The World Health Organization defines air pollution as “the presence of materials in the air in such concentration which are harmful to man and his environment.” ADVERTISEMENTS: In fact air pollution is the occurrence or addition of foreign particles, gases and other pollutants [ ].
One of the main causes of acid rain is a sudden drop in the pH levels of water and that happens because of absorption of harmful gases by the atmosphere. The best way to restore the pH balance of water is to limit the use of items which run on gasoline.
