Do you want to know what acid rain is and its impact on nature? It is important to know about this type of rain, as it is closely related to pollution and other similar problems in nature. Acid rain is formed by the combination of humidity in the air with sulfur dioxide, sulfur trioxide, and nitrogen oxides, which are found in pollutants such as petroleum products, waste, and factory and vehicle fumes, and so on. If you want to know in depth everything about this environmental problem, at Ecologista Verde we tell you the details about the acid rain its definition, causes and consequences, among other aspects such as possible solutions.
According to the Dictionary of the Spanish language of the Royal Spanish Academy, to which we can go to answer what acid rain is and, in fact, it is the best option to know its strict definition, the definition of acid rain is "The precipitation in the atmosphere of industrial emissions of acid pollutants". Thus, it can be defined as the mix of rainwater with environmental pollution or air pollution. It is an atmospheric phenomenon that poses serious problems for the planet, both for all of nature and for the artificial infrastructures built by man. Do you want to know better why this is so? We will explain it to you below.
As we have already mentioned, the causes of acid rain are directly related to environmental pollution, we could say that the direct causes are human activities through factories, heating, power plants, vehicles, etc., that burn sulfur-containing petroleum derivatives and also burn coal.
Now that we have clarified What is acid rain as well as the main causes of acid rain, there are more aspects to deal with to better understand this environmental problem. What specifically produces acid rain? What are its components? and how is it formed? These are common doubts about this atmospheric phenomenon, since to find solutions it is necessary to know well the origin of the problem. Keep in mind that rain contains carbon dioxide, as well as any other form of environmental water such as snow, ice or fog. This makes this water a bit acidic in itself, over a pH of 5.6, but acid rain has a pH of 5, and can reach one of 3 when it is very acidic.
The acid rain It is formed when the water contained in the air, that is to say moisture, comes into contact and mixes with nitrogen oxides, sulfur dioxide and sulfur trioxide. These are gases that together with water produce sulfuric acid, sulfurous acid and nitric acid, causing the rain to become more acidic than it already is and, when falling, damage the environment in which it is found.
After knowing the definition of acid rain, its causes, its formation process, only one detail remains to be clarified to better understand this problem before addressing the effects and consequences of acid rain on the environment and for people. It is about knowing exactly the basic components of this rain, which allows its better understanding and that it is somewhat easier to think of solutions.
The formulas of the primary components of acid rain, that is to say, its precursors, are the following:
The formulas of the acids resulting from the previous mixture that acidify the humidity forming the acid rain itself are the following:
When combined with environmental humidity, these substances precipitate in the form of acid rain, falling on the earth, water, forests, buildings, etc., damaging everything due to its acidity. Therefore, acid rain deteriorates the environment.
In addition, the pollutants that are expelled by the burning of petroleum derivatives with sulfur, coal, etc., not only pollute the air and humidity of the area in which they are created, but can also travel long distances on the wind, up to thousands of kilometers, before combining with humidity, turning into acids and falling in the form of precipitation, either the rain itself or snow, hail, fog, etc. This means that pollution can be created in one part of the world, but the acid rain from that pollution can precipitate in another part of the earth.
Between the effects and consequences of acid rain we find the following:
In summary, acid rain impoverishes soils, plants and waters, damages aquatic, terrestrial and aerial life and is related to the greenhouse effect.
After knowing what it is, the causes and consequences of acid rain, we are left to think about solutions. Do youWhat steps can be taken to decrease acid rain? This is a question that we have been asking ourselves since the 1980s, when there was awareness on this issue and solutions were sought through treaties and laws with the aim of reducing pollution and, therefore, the acidity of rainfall and other environmental problems.
These are some solutions that provide answers to how to reduce the impact and how to avoid acid rain, focusing above all on reducing the emissions of the pollutants that cause the problem:
