Air Pollution Caused by Industries

Our activities affect the environment and. the environment affects our health. As the number of humans on earth increases, our agricultural and industrial activities have a greater impact on the environment, particularly on the atmosphere. As our most precious resource, the atmosphere has been polluted, so it is imperative to take measures to control air pollution. It becomes necessary to know what the sources have been and how they operate. In this chapter, we first introduce five main air pollutants: carbon monoxide (CO), hydrocarbons, particulate, oxides of sulfur (SOx), and oxides of nitrogen (NOx). We then present the industrial emissions inventory. Finally, we analyze the character of air emissions from five main industrial sectors that are combustion sources: the petroleum industry, chemical industry, metallurgical industry, construction material industry, and paper and pulp manufacturing. The emission factors are based on the present processes. With the innovation of processes and the implementation of clean production, the factors will decrease gradually.
