Air pollution
02/12/2016
As the Earth’s atmosphere air is used practically in every sphere of human economic activity. Even if air is not directly involved as raw material in a production cycle it is an integral part of any technology due to its regenerative and assimilating properties.
Air is widely used as a necessary component in ferrous and non-ferrous metallurgy, the chemical and petrochemical industries, the thermal energy sector, construction materials production, and manufacturing. Atmospheric pollution includes transport and air exhaust as well as effects of space exploration at these industries’ current level of development.
