What is air pollution definition in environmental chemistry?
Air
pollution is a burning problem in the whole world today. If the density of
solid waste or unwanted matter in the air exceeds the normal ratio due to
various natural and man-made causes, then this type of air is called polluted air and this process is called
air pollution.
If excessive amounts of gaseous substance that are harmful
to life and the environment, are increases in the air, then this type of air
are called polluted air.
Air
pollution is most harmful for human civilization and this
problem causes the most damage at the fastest rate.
The air polluting substance damages the life circle of
the living world and also destroys the quality of a
wide area.
What are the sources of air pollution in environmental chemistry?
The presence of different gaseous substance such as, CO, NO, NO2, SO2, CO2, H2S,
NH3, CH4, dust particle, smoke etc in the air are the
causes of air pollution.
There are different sources from which these gaseous
substances enter into the air and create air pollution. The entire sources are divided into categories.
- Air pollution due to natural cause and
- Air pollution due to man-made causes
Air pollution due to natural cause
There are few natural causes of air pollution. These
are discussed below.
The gaseous substances SO2, H2S,
CO etc emit due to volcanic eruption
and enter into the atmosphere that pollutes air.
The gaseous matter those are produced from the
decomposition of the organism and directly enter into the air.
A huge extent of dust particle from forest fire and
dust storm enter the atmosphere that causes of air pollution.
Also, virus, bacteria, yeast, flower pollen etc enter
the atmosphere and pollute air.
Air pollution due to man-made causes
The man-made causes of pollution are most responsible
for air pollution. Most of the pollutants are created due to any type of human
activity.
The sources of all type of pollutants those are
responsible for air pollution, are discussed below.
The gaseous pollutants such as CO, CO2 and
fly ash those emit from thermal power station and mixed with air.
The various acid vapor (SO2, NO, HCl, CS2)
and acidic gaseous matter that are used as raw material, emit from acid
production industry. These pollutants enter the atmosphere and pollute air.
The gaseous substance that emits from ammonia
production industry and also from the usable space, these enters the atmosphere
and pollutes air.
The gases such as, SO2, CO etc and fine dust
particle that emit at the time of heat oxidation, calcinations or crushing
process of metal extractions.
Also, the gaseous substances due to combustion of
fossil fuel enter the atmosphere and pollute air.
