1. Health problem: the health effects caused by air pollution
include difficulty in breathing, wheezing and coughing. Prolonged exposure to
air pollution can lead to severe complication such as chronic respiratory and
heart condition.
Illness related to air pollution
includes asthma, bronchitis, emphysema, and other lung and heart disease and
respiratory allergies.
2. Higher rain acidity: When sulphur dioxide or nitrogen dioxide combine
with water vapour in the atmosphere they form dilute acidic solution.
These solutions reach the earth in form of acid rain.
Acid rain damage forests and
corrodes many ancient building and sculptures made or marble.
3. Depletion of ozone layer: is the layer of gaseous ozone (O3) in the
stratospheric atmosphere. The layer protects the earth from harmful radiation
by filtering out harmful ultraviolet radiation from the sun radiation.
Gases such as nitrogen monoxide,
nitrogen dioxide and CFCs contribute to the depletion of the ozone layer. When
the ozone layer is depleted, harmful radiation from the sun reaches the earth.
This radiation causes serious illness such as cancers, blindness and skin
ailments.
4. Global warming : is the increase of average temperature near or on
the surface of the earth, as a result of what is known as the Greenhouse effect
caused by greenhouse gases. Greenhouse gases in the atmosphere acts like a
mirror, reflecting back to the earth the heat radiation which would otherwise
be dispersed into space.Global warming may result in the
melting of ice caps causing an increase in water level in the oceans. Thus may
cause flooding in many coastal regions.
5. Eutrophication: Eutrophication is a condition where high amount
of nitrogen present in some pollutants gets developed on sea’s surface and
turns itself into algae and and adversely affect fish, plants and animal
species. The green colored algae that is present on lakes and ponds is due to
presence of this chemical only.
6. Effect on Wildlife: Just like humans, animals also face some
devastating affects of air pollution. Toxic chemicals present in the air can
force wildlife species to move to new place and change their habitat. The toxic
pollutants deposit over the surface of the water and can also affect sea
animals.
7. Reduced visibility: Smog reduce visibility making activities such as
driving very difficulty.
