摘要

Air pollution has become a major problem in terms of both human health and the negative effects it has on the environment. According to studies, it can be seen that concentrations of air pollutants continue to be high, although it is speculated that they will decrease in recent decades. A key problem of air pollution both locally and in the hemisphere is related to the fact that air pollutants emitted in a certain area can also affect surrounding areas. Thus, pollutants can be transported through the atmosphere, leading to reduced air quality in other areas. Pollutants, regardless of their nature, are found in the atmosphere in various shapes or sizes. The hierarchy of air pollutants comprises two important categories: natural and anthropogenic. Natural phenomena that can contribute to the formation of natural pollutants include: dust carried by the wind, volcanic gases and ashes, ozone from lightning and ozone from ozone layer, ester and terpenes from flora, smoke, gases and flying ashes from burning forests, pollen and other aero-allergic, gases and smells from biological activities, natural radioactivity. These phenomena have produced pollution so far and constitute that portion of the critical situation in which pollution is located, on which the activities trying to control may have little or no effect. Anthropogenic phenomena are the result of human comfort.
