Air pollution is a burning issue all over the world now. Problems like global warming are taking the planet into its grab fast. In recent time we can witness disastrous results like Tsunami, Cyder and Earthquake in China very recently.

To define, air pollution is the human introduction into the atmosphere of chemical, particulates or biological materials that leaves negative impact in the lives of lives. Air pollution can bring disasters including death. Air pollution is caused due to emission by the automobiles mainly. Climate scientists have identified Co2 as the main pollutant.

India is one of the worse affected countries in the world. The country with second largest population in the world suffer a lot due to air pollution. It can be mentioned that Kolkata is the highest polluted cities among the metro and major cities in the country. Last year Kolkata has recorded a highest level of air pollution among the metro cities in India.

Studies show that air pollution in kolkata increases during the winter days. It happens mainly due to inversion, low wind speed and high level of congestion. Data available on the suspended particulate matter (SPM), for the last two years, shows that the SPM is continuously increasing during the winter in last few years. Lead concentration in SPM during winter for kolkata was high in comparison to other cities of the world. Concentration of some components like benzene, toluene and xylene are found in kolkata in a level much higher than the any other places in the world.

Chittaranjan National Cancer Institute has recently conducted a study that shows that air pollution is the major reason behind fatal diseases like lung cancer among the city dwellers. The city has recorded a highest number of lung cancer cases in the country last year. CNCI report also include that the city’s SPM is 211 and Respiratory Particulate Matter (RPM) is 105. Both are much higher than the normal level. As a result of this breath abnormalities, difficult breathing are some of the problems people have to suffer regularly. The slum dwellers, street workers, hawkers are the worst sufferers.

There are a number of reasons behind the growing pollution in the city. Factors like use of kerosine, coal– both in domestic and industry works, add much to the pollution in the city. Other than that poor quality of fuel, old age cars, poor condition of the road, miserable slum condition, high population density are together responsible for the growing pollution in the city. Moreover, deforestation is another factor that counts a lot. It is a wonder that the high court has ordered to control the emission in of the vehicles, but the govt has taken no steps so far.
