The last 72 hours of Kolkata meddled with severe pollution levels worse than Delhi- the highly polluted city of world.
The overall PM 2.5 count at Kolkata’s Rabindra Bharti University (RBU) on Thursday was 381, compared to 292.25 in Delhi’s Ashok Vihar, one of the capital’s most polluted localities. The air quality in Kolkata remained worse than Delhi on Friday, although it improved in comparison to the capital on Sunday.
Environmentalists discern that this was due to proactive measures against pollution in Delhi and complacency in Kolkata. According to experts Kolkata has more vehicle run on petrol which contributes to the pollution.
Delhi’s air quality slipped to the “very poor” category due to slow wind speed and high humidity on Sunday, authorities said.
The capital’s air quality had shown significant improvement on Wednesday and Thursday after rain washed away the pollutants, but the rainfall also led to increased air capacity to hold pollutants, the SAFAR said.
