What is smog?

SMOG is an air pollution of a particle characterized by low visibility and a range of problems with human health. There are several types, including naturally created volcanic smog or VOG, and in many parts of the world, efforts have been made to reduce the amount of smog. Many people do not realize that the most entertaining part is often invisible, and specialized scientific instruments are needed to get a precise picture of this pollution to create this term in 1905, when Harold Antoine des Voeux wanted to come up with the word to describe the heavy fog unique to London. He created Portmanteau "fog" and "smoke" that quickly lifted a number of newspapers. The type described by Des Voeux was an industrial smog caused by burning materials such as coal. London has been plagued with this pollument for centuries, and with numerous visitors to the city commented on it ever.

Another type is photochemical smog, CAV atmosphere is used by a chemical reaction between oxygen, hydrocarbons and other specific matters. For SPThe wound conditions oxidize these particles and form ozone and nitrous oxide. This is a type associated with cities such as Los Angeles, caused by sunny days and numerous vehicle emissions.

SMOG is required certain meteorological conditions. Correct weather is usually accompanied by stagnant winds and inversion of air in which hot air pushes into colder air below it, concentrates pollution near the ground. Visibility can be covered, as is the case with industrial types, or it may only seem foggy in the case of photochemical. Looking from a distance, the concentration of photochemical smog is becoming brownish orange.

Many people suffer from smoggic conditions, including children and elderly. People with respiratory conditions can start to feel good because this pollution is very difficult on the airways. Eyes and nose slisies can also irritate, leading to pain and discomfort. ExceptThis is smog harmful to plants and animals. Persistent pollution can damage crops and cause long -term health problems for pets and livestock. Finally, it can become corrosive and harmful buildings and vehicles. Industrial smog is particularly well known for this and several major historical places around the world, such as Parthenon, is threatened by corrosion.
