The word pollution comes from the Latin pollutant and refers to the action and effect of polluting. This verb, for its part, is used to refer to the harmful alteration of the purity or normal conditions of a thing or a medium by chemical or physical agents.
To contaminate is also to alter the form of a word or text by the influence of another; pervert and corrupt faith or customs; and desecrate or break God’s law.
In short, contamination is the introduction into any medium of a contaminant. The most common use of the term occurs in the field of ecology with what is known as environmental pollution, which is the presence in the environment of any agent (physical, chemical or biological) in places, forms and concentrations that can be harmful for the health, safety or well – being of the population.
The dynamics of pollutants is responsible for studying the action of these agents from the moment they are generated until their final disposal. Among the phenomena of dynamics are dispersion, concentration, transfer and transformation.
As for the classification of pollution depending on the environment concerned, one can speak of the air pollution, the pollution of the water, the contamination of soil and noise pollution, among others.
Going a little further into analyzing the various types of pollution, we can establish that the atmospheric call is one that, as its name indicates, consists of releasing a series of chemical substances into the atmosphere, resulting not only in its being modified but also also to a serious risk to the health of any living being.
In this sense, we must also state that much awareness is being taken of the need to care for and protect the environment from this type of contamination. For this reason, environmental sustainability projects and initiatives are emerging that reduce the levels of CO2 that are released into the atmosphere with the clear objective of improving the quality of life of citizens.
In the case of aquatic pollution, what is produced is the release of waste, such as garbage or sewage, which reaches rivers and seas. Meanwhile, in the soil, what takes place is the penetration into the earth of chemicals that are harmful to it.
Finally, the aforementioned noise pollution is one of those that has taken more prominence in our current society. Especially in cities around the world and it is in them where any citizen is more exposed to not being able to fall asleep or not being able to carry out their life in a relaxed way as a result of the noise of traffic or of planes taking off and land at their airports.
Finally, it should be noted that the classification of pollution based on the environmental pollutant method can be chemical, radioactive, thermal, electromagnetic and microbiological, for example.
