Recently, Supreme Court has banned the sale of crackers in New Delhi till 31st October 2017. Although, this step will decrease the level of air pollution in New Delhi, but it will not solve the problem of New Delhi completely. Further, out of all four important metro cities in India, Delhi has worst air quality this is because of following reasons.

  • Due to burning of paddy crops field in the near states of New Delhi like Western Uttar Pradesh, Haryana and Punjab bring the smoke/pollutant from those states and collect over the atmosphere above New Delhi
  • The geographical location of New Delhi doesn’t allow its encounter with land and sea breeze
  • The number of vehicles is quite high in Delhi and NCR. Nox emitted by vehicles and burning of fire crackers are important reasons of frequent Photochemical smog in Delhi.
  • Industrial region around the NCR is also one of the factor
  • Due its continental position dust particles around the city lies surrounding the cities.
