You might have read in the newspapers that respiratory problems amongst children are rising day by day. Many respiratory problems are Caused by air pollution . Have you noticed how rapidly the number of vehicles is increasing in our cities?

Impact On Respiratory Organs 

Vehicles produce high levels of pollutants like carbon monoxide,carbon dioxide, nitrogen oxides and smoke. carbon monoxide is produced from incomplete burning of fuels such as petrol and diesel it is a poisonous gas it reduces the oxygen carrying capacity of the blood.

vehicles as Pollutants

Other kinds of pollutants are chloroflurocarbons (CFCs] which are used in refrigerators, air conditioners,and aerosol sprays.CFCs damage the ozone layer of the atmosphere . Recall that the ogone layer protects us from harmful ultraviolet ultraviolet rays of the sun.

other for pollutants

Air consists of a mixture of gases .By volume ,about 78% of this mixture is nitrogen and about 21% is oxygen. Carbon dioxide, argon ,methane,Ozone and water vapour are also present in very small quantities, Nearly 1 %.

Constituents Of Air 

You may have covered your nose while passing a brick kiln emitting smoke or started coughing while walking on a busy road ,on the basis of your experience, compare the quality of air at the following places;⊙a park and a busy road●a residental area and an industrial area ⊙A village and a town

A Congested Road 

Sometimes, pollutants may come from natural sources like smoke and dust arising from forest fires or volcanic eruptions. Pollutants are also added to the atmosphere by certain human activities, like factories, power plants, automobile exhaust and burning of firewood and dung cakes .

How Does Air Get Polluted

We can survive for sometime without food but we cannot survive even for a few minutes without air.

This new edition of the premier air pollution textbook is completely updated and revised to include all components of the 1990 Clean Air Act Amendments. Fundamentals of Air Pollution, Third Edition covers the spectrum of topics pertinent to the study of air pollution: elements, sources, effects, measurement, monitoring, meteorology, and regulatory and engineering control. In addition, the textbook features new chapters on atmospheric emissions from hazardous waste sites, air pathways from hazardous waste sites, and the long-term effects of air pollution on the earth.
