Air pollution: ways to forecast and calculate it

Air pollution: ways to forecast and calculate it

In recent years, the fight against air pollution has become global. Humanity, at least when we are speaking about developed countries, starts to realize finally that the Earth is our common home which can get not suitable for living in the near future. Atmospheric pollution takes place when substances harmful for living creatures diffuse throughout the surrounding air, and then this destructive activity has its toxic impact later since it causes global changes of climate of the Earth.

 Processes of global warming, oxidation of world ocean, melting of the ice caps at the poles, thinning of the ozone layer, dense smog over metropolitan areas – these are only a part of the problems that have arisen as a result of air pollution. Generally speaking, air pollution is a penetration of physical, chemical and/or biological contents into air that are usually not common for air, or a change of natural concentration of these contents in the air.

Smog. The importance of accurate and timely data on air pollution

Smog. The importance of accurate and timely data on air pollution

Word Smog (smoky mist) comes from the fusion of the English words «smoke» - smoke and «fog» - fog. Smog - one of the most common types of pollution that can be seen clearly. It is formed by the reaction of products of incomplete combustion of fossil fuel such as coal with water droplets in the fog. Usually among carbon contaminants are CO2, nitrogen dioxide, sulfur dioxide NO2 S02 and other elements, and their reaction with the water drops in the mist form corrosive acids. As a result of inhalation of smog there is a sensation of breathlessness and cramps in the throat, a drop of acid attacks the mucous membranes of the respiratory tract that can cause (or worsen), asthma, chronic bronchitis, emphysema, as well as eye irritation and decreased immunity, or death. This is the smog in December 1952 in London that killed at various data from 4000 to 6000, which led to the emergence of the first laws aimed at preserving the environment.
