Air quality has also been impacted due to the negligible movement of vehicles in the lockdown announced to prevent coronavirus infection. This can be gauged from the decline in air pollution levels in cities like Dehradun, Rishikesh, Haridwar, Rudrapur, Kashipur, and Haldwani. At this time, the pollution level in these cities has come down from 75 to 65 percent of the maximum limit. Apart from this, the air in the mountainous areas is also very clear. The cleanest air is blowing in Chamoli and Pithoragarh districts. Here air pollution was found to be 86 percent below the maximum limit.
This situation of air pollution was revealed by the satellite data of the international website ‘Windy’. This website assesses the air quality at PM-2.5 and the maximum level should be 60 micrograms per cubic meter in 24 hours. In a lockdown, Uttarakhand Environmental Protection and Pollution Control Board is not measuring air pollution.
The board’s last figures are as of March 14 and the maximum level of 2.5 in Doon was 97.69 micrograms per cubic meter. This level (on the ISBT site) was found to be slightly higher at 101 in February. In Doon on Monday, the level of 2.5 was found to be 15 micrograms per cubic meter in the morning, while it was at 16 in the afternoon.
