In pictures: Air pollution in Delhi 9 times over acceptable limit
Winter is coming
Each year, with the onset of winter, a haze begins to settle down over Delhi.
Farming to blame?
The reasons are numerous and include the burning of leftover crop stubble by farmers in north India and colder temperatures which cause something called 'lateral inversion'. The cold prevents air from rising, thereby trapping pollutants closer to the grounds.
After a relatively cleaner Sunday — the result of higher wind speeds which pushed pollutants out of the city — pollution in Delhi rose sharply on Monday. Doctors have said breathing in Delhi's air is akin to a 'death sentence' for people with lung and respiratory disease. The sale of face masks obviously shoots up.
A hazardous haze
At 10 am on Monday morning, AQI or air quality index levels were recorded at over 900 (Anand Vihar) at at least one spot in Delhi. Anything over 300 falls in the hazardous category. An AQI of over 900 is over nine times the acceptable (100) limit (The AQI at Anand Vihar however down to 388 by 1 pm. 10 am remember is peak traffic time.)
This though is just beginning of the cold season. By the time, late December and early January come around, Delhi begins to look like something out of a movie set in a dystopic future.
