Acid Rain Formation And Its Causes On The Environment: Definition Causes Effects Control Prevention

Today we talk about acid rain formation and its causes on the environment . Acid rain is based on climate changing due to deforestation and many more things. It refers to more to a mixture of deposited material, both wet and dry. It coming from the atmosphere containing more than normal amounts of nitric and sulphuric acids. Simply put, it means rain that is acidic in nature due to the presence of certain pollutants in the air due to cars and industries processes.

Today we talk aboutacid rain formation and its causes on the environment. It refers to more to a mixture of deposited material, both wet and dry. It coming from the atmosphere containing more than normal amounts of nitric and sulphuric acids.

Acid rain can occur in form of rain, snow, fog or dry material that settle to earth. Acidity is determine on the basis of the pH level of the water droplets. Normal rain water is slightly acidic with a pH range of 5.3-6.0, because carbon dioxide and water present in the air react together to form carbonic acid, which is weak acid. When the pH level of rain water falls below this range, it becomes acid rain.

It occurs due to natural and human activities and acid rain formation and its causes on the environment. Erupting volcanoes contains some chemicals that can cause acid rain. Apart from, this burning of fossil fuels, running of factories and automobiles due to human activities are few other reasons  behind this activity.

Forms of acid rain

There are two forms in which acid deposition occurs- wet and dry. Both are discusse below:

  1. Wet Deposition :- 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. It removes acid from the atmosphere and deposit them on the earth’s surface. When the acid flows through the ground, it affects large number of plants, animals and aquatic life.

  1. Dry Deposition :- 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. Almost 50% of the acidic pollutants in the atmosphere fall back through dry deposition. These acidic pollutants can be wash away from earth surface by rainstorms.

It was discover way back in 1800s during the Industrial Revolution. A Scottish chemist, Robert Angus Smith, was first to discover this phenomenon in 1852 as a relationship between acid rain and atmosphere pollution in Manchester (England), but it gained public attention mainly in 1960s.

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 cause by combustion of fossil fuels, which results in emissions of sulphur dioxide and nitrogen dioxide.

Natural resources such as erupting volcanoes, rotting vegetation and sea sprays produce sulphur dioxide and fires, bacterial decomposition and lightening and oxygen and are disperse over large areas because of wind patterns.

Man-made sources include emission of sulphur dioxide and nitrogen oxides due to combustion of fossils fuels. Roughly two-thirds of all sulphur dioxide and one-fourth of all nitrogen oxides  come from generation of electricity through burning of fossil fuels such as coal.

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 get run off the forests, roads ans fields to flow streams, rivers and lakes. Over a period of time, acids get accumulate in the water and lower the overall pH of the water body.

  • Effect on soil :- As it falls on forest or field soil, it kills useful micro-organisms and leaches nutrients of soil. Many a times, the leads to calcium and other nutrient deficiency, producing infertile soils.

Control of acid rain

  • Emission of SO2 and NO2 from industries and power plants should be reduce by using pollution control equipment.
  • Use of sulphur free or low sulphur petroleum in the automobiles.
  • A coating of protective layer of inert polymer should be given in the interior of water pipes for drinking water.

‘Hello World’ Today we talk about Acid Rain. Acid rain is based on climate changing due to deforestation and many more things. It refers to more to a mixture of deposited material, both wet and dry. It coming from the atmosphere containing more than normal amounts of nitric and sulphuric acids.
