New Delhi: According to a report by WHO, air pollution in Delhi has gotten worse since 2011 sparking higher risk of heart stroke, lung disease and cancer. The Experts assert that breathing in Delhi's air for 24 hours is equal to smoking 10 cigarettes a day.

The 2014 report of the Ambient Air Pollution (AAP) database holds results of outdoor air pollution checking from almost 1600 cities in 91 countries.

The WHO reports that the situation is grave in Delhi. The air in Delhi has PM2.5 concentrations of 153 micrograms and PM10 concentrations of 286 micrograms which is much more than the permitted limits.

Two crore people who are under the influence of Delhi's polluted air, are expected to suffer nasal, respiratory and chronic diseases. The affect is much greater among children.

The 'Heal Foundation' reports that four out of 10 children in Delhi have lung problems. A lung screening test on children between the age group of 10-14 discloses that 21% of them have weaker lungs in comparison to Mumbai and Bangalore where the percentage is 13% and 14% respectively.

The need of the hour is to implement proper policy framework on the matters concerning environment and pollution.
