Pollution through Automobile, Power Plant and Industries State of Art: A Review

Our activities affect the environment and. the environment affects our health or human being. As the number of people on earth increases, our agricultural and industrial activities have a greater impact on the environment, particular on the atmosphere. It becomes necessary to know what are the sources which affect the environment. In this paper ,first we introduce five main air pollutants such as carbon monoxide (CO), particulate, oxides of nitrogen (NOx), oxides of sulphur (SOx) hydrocarbons. Finally, we analyze the air emissions from five main sectors that are combustion sources: coal combustion, fuel combustion, oil combustion and industries waste . The emission factors are based on the present activity. With the innovation of processes and the implementation of clean production, the factors will decrease gradually. The atmosphere has been polluted, so far to take measures to control air pollution.
