Types: Air Pollution

Overview

Air pollution is indication of disturbances to the composition of compounds in the atmosphere, as it may be summarized as shown:

• excess emission of gases/vapors into atmosphere

• saturation of chemical compounds/particulates

• rate of dissipation < (smaller than) rate of absorption through various cycles (i.e. carbon and nitrogen cycle)

• emergence of new chemical reactions of reactive and non-biodegradable compounds.

Global warming, acid rain, smog, ozone depletion are some effects of air pollution.

Sources and Methods

We can classify major sources that lead to air pollution to the following categories:

• motor vehicle exhaust

• heat and power generation facilities

• industrial processes

• auto manufacturing

• fertilizers plants

• building demolition

• solid waste disposal

• solvent evaporation

• volcanic eruption

• fuel production

• roadway construction

• electrical components manufacturing

• extraction of metals

• forest fires

• agriculture
