Every year, the pollution levels in Delhi, one of the most polluted cities of India, increase as Diwali draws closer. And this year, unfortunately, was no different despite rallies and campaigns to celebrate the festival of lights without crackers.
As was expected, the air quality in the national capital deteriorated alarmingly with the pollution levels reaching as much as 23 times higher than normal.
According to real time ambient air quality data of the Delhi Pollution Control Committee , the Respirable Suspended Particulate Matter (RSPM) has increased manifold.
