Dehradun recorded a significant improvement in air quality on Wednesday, with its average Air Quality Index (AQI) dropping to 47 from 104 a day earlier, placing it in the ‘good’ category. In contrast, Delhi continued to breathe heavily polluted air, with its AQI standing at 313 in the ‘very poor’ category.
According to the Central Pollution Control Board (CPCB), Dehradun’s PM10 level stood at 47, while Delhi recorded high concentrations of both PM2.5 and PM10, at 313 and 299 respectively.
The contrast between the two cities was particularly striking, with Dehradun’s AQI falling below 50 while Delhi’s remained above 300.
The improvement in Dehradun’s air quality comes as a relief to residents, although pollution levels can fluctuate depending on weather conditions, wind speed and other local factors.
Delhi, meanwhile, continued to experience very poor air quality, raising concerns over the health risks associated with prolonged exposure to high levels of particulate pollution.
