Acid rain

We explain to you what acid rain is and the causes of this environmental phenomenon. In addition, its effects and how it would be possible to stop it.

Acid rain is dilutions in water of carbonic, nitric, sulfuric or sulphurous acid.
  1. What is the acid rain?

It is known as `` rainy acid '' to an environmental phenomenon of a harmful nature, which occurs when, instead of water, it precipitates from the atmosphere cidosorgnicos various forms of product of the chemical reaction entrealgunos TYPESOF oxides Ellay gaseosospresentes in the condensed water vapor In the clouds. These organic oxides represent an important source of air pollution.

Acid rain is usually not strictly acidic, but various dilutions in water of carbonic acid, nitric acid, sulfuric acid or sulphurous acid, depending on the pollutants that abound in a region, since winds can mobilize these gases over kilometers away.That chemical reaction usually occur as follows, for example:

SO2 (gaseous sulfur dioxide) + OH (hydroxyl present in the atmosphere) = HOSO2, which in turn reacts with the ambient oxygen: HOSO2 + O2 = H2O (water) + SO3 (sulfur trioxide), and the latter, highly polluting compound, reacts with water to produce H2SO4 (sulfuric acid).

The result of this mixture is usually around pH levels of 3 (similar to vinegar), which is much more acidic than the normal rainfall of 5.65 (due to the regular presence of CO2). Atmospheric that gives rise to minimal amounts of carbonic acid).

In addition, this type of rainfall is usually affected by temperatures and weather, and may occur in the form of dew, mist, hail, drizzle or even snow . However, its presence in the diverse ecosystems is usually pernicious, since they alter the chemical balance of the earth, water and deteriorate life.

  1. Causes of acid rain

The combustion of fossil fuels can cause acid rain.

As we have seen, the main direct cause of acid rain is the presence in the atmosphere of various polluting organic substances, such as sulfur and nitrogen oxides, which are often frequent by-products of various human and industrial processes such as:

  • Combustion of fossil fuels . Typical of cars and vehicles that consume hydrocarbons such as coal, or petroleum products.
  • Industrial boilers As those present in power generation plants (especially coal), factories, metallurgical plants and other industrial plants.
  • Heating . Many heating devices release this type of gases into the atmosphere during operation.
  1. Effects of acid rain

Acid rain has various environmental effects, ranging from the gradual deterioration of plant life, whose leaves do not support the acidity of dew or rain, to the acidification of large bodies of water such as rivers or lakes, which often It makes them uninhabitable by the weakest life forms, causing chemical and trophic imbalances that can lead to extinctions or overpopulation.

Another known effect in this regard is the deterioration of soils, since the acid molecules contribute protons to the soil (H +), forcing the production of certain ions (iron, calcium, aluminum, zinc or lead cations) and depleting the soil chemistry, which becomes less fertile and less suitable for cultivation.

In addition, acid rain is corrosive, so it deteriorates buildings and deteriorates materials, dissolving marble or limestone from statues, churches and period buildings .

  1. How to stop acid rain?

Promoting public transport can be an alternative to prevent acid rain.

Measures to prevent the formation of acid rain always go through a greater awareness of the polluting effects of the industrial world, and therefore effective control measures on the gases that we put into the atmosphere. Some usual measures are:

  • Reduce the sulfur in fossil fuels and force drivers to use catalytic converters in their vehicles (public and private).
  • Migrate to green technologies, or at least safer for the environment, especially in terms of obtaining electrical energy.
  • Add alkaline compounds to lakes and rivers to neutralize the pH when the presence of acid rain is detected.
  • Ensure an industrial model that controls the emission of sulfur oxide or nitrogen gases, or in any case offer alternatives to neutralize said gases before they are discharged into the atmosphere. Sphere
  • Encourage public transport and eco-healthy alternatives to the use of the motor vehicle.
