Examining the role of Natural phenomena in intensifying air pollution in cities

چکیده

The purpose of this article is to identify the majority of natural pollution phenomena in urban air in recent years. The environmental pollution situation is worrying that today the annoying people killed and injured the air pollution drivers of the air pollution fields of disasters. The people move and live outside the suburbs of the cities. The purpose of writing this paper is to identify the non-human factors of air pollution in cities that have so far received less attention. This paper is based on the study and analysis of a collection of documents and articles on the causes of air pollution in the city using the research methods of the request. From the factors of urban air pollution, we assumed that in addition to the displacement of human reproductive sources, natural factors of external violence are likely to intervene. Let us conduct systematic research on the hypothesis that the causes of air pollution in the city. Smoking, industrial growth, increase in energy consumption and lack of urban affairs programs should be investigated in addition to other natural causes. Factors: Name the occurrence of inversion, mountainous topography of the city, lack of rain, persistence of cold fronts, increased air pressure and poor coverage.Natural sources of air pollution in cities should be separate and far from the rules and regulations of all human-caused sources. However, there are no effective natural factors of air pollution that can be controlled and the only solution is to eliminate the exacerbation of natural factors of air pollution. There are no humans left. The guidelines for identifying the effective natural factors of air pollution should help the city environmental authorities themselves to identify the effective natural factors of air pollution.
