The intensity of air pollution is increasing in Delhi and with winter around the corner the conditions may deteriorate further. Here are a few reasons why air pollution in Delhi gets so bad.
Delhi shares its border with the states of Haryana, and Uttar Pradesh. One of the main reasons for increasing air pollution is stubble burning by the farmers in these states.
Another contributing reason is pollution caused by the traffic menace in Delhi. The Central Pollution Control Board (CPCB) and the National Environmental Engineering Research Institute (NEERI) have declared vehicular emissions as a major contributor to Delhi's increasing air pollution.
Delhi falls under one of the major industrial regions of India, i.e. Gurgaon-Delhi-Meerut Industrial Region. The industries that have the potential to affect air quality are chemical, steel, cement, mining, thermal power plants, etc and most of them can be found in this region.
Construction activities in Delhi-NCR are another reason that contributes to the increasing dust and pollution in the air.
Due to stagnant winds in winter, pollutants present in the air get locked and affect weather conditions, resulting in smog.
The flat plan where Delhi sits is circumscribed by the chain of mighty Himalayas and hills that block the movement of air. So, when smoke and dust build up, they immediately suspend and remain hanging in the air.
