Although Delhi is still suffering from high levels of pollution, it has managed to control the environment better this year as compared to the last, officials in the Delhi government said.
Data shows that November this year was significantly less polluted as compared to last year. A Delhi Environment department official was also quoted saying-
The environment department, transport department and civic bodies are responsible for controlling pollution in Delhi and the merging of Diwali and crop residue burning season coincided this year which lead to lower levels of pollution!
Air Quality Index data from the Central Pollution Control Board shows that while there were 7 severely polluted days (AQI above 400) in the month last year, this year there were 5.
The peak pollution was also low, with the highest AQI of 486 last year as compared to 426 this year.
The number of very poor air quality days (AQI between 301 and 400) was 19 last November as compared to 16 this year. Delhi saw 7 poor air quality days (AQI between 201 and 300) this year as compared to 3 last year.
This year there was one moderate air quality day (AQI between 101 and 200) and there was none last year. So something is better than nothing for sure.
But we cannot breathe a sigh of relief yet because according to the meteorological department officials, Delhi's air quality is expected to "significantly deteriorate on Sunday due to a decline in temperature which might lead t to entrapment of pollutants.”
Although it has also been predicted that the pollution levels will stay in the poor category and will not touch severe levels.
