Covid curfew improves air quality in Dehradun even more than last year’s Lockdown
In most of the cities of Uttarakhand, the air was purified during the Covid curfew
In most of the cities of Uttarakhand, the air was purified during the Covid curfew. The surprising thing is that the air has been purified during the Covid curfew in Haldwani and Rishikesh compared to the lockdown last year. However, an increase in air pollution has been reported in Kashipur. The Uttarakhand Environmental Protection and Pollution Control Board released the Air Quality Index data on Sunday. As per the data, the air quality index of Haldwani and Rishikesh was 92 and 92 in the last year's lockdown in May, which was found to be 79 and 89 respectively in May this year. This means that the air was purified after closing everything in lockdown in these two cities last year, this time the air was found to be much cleaner than it was in Covid curfew, with many services open.
The air quality index in Dehradun in March this year was 237, which was 127 in May, 120 in March in Haridwar, which was 101 in May. The air quality index in Kashipur was 114 in March, which rose to 116 in May. Rudrapur recorded an air quality index of 119 in March and only in May.
Dr. Ankur Kansal, Environmental Scientist, Pollution Control Board said that more rain and outflow of wind in the state could be the reason for the improvement in the air quality index, although the Covid curfew is also a big reason.
