At 4 pm, Delhi’s air quality index stood at 79, which falls in the ‘satisfactory’ category.
The national capital’s air quality has been oscillating between ‘good’ and ‘satisfactory’ categories.
An AQI between 0-50 is considered good, 51-100 satisfactory, 101-200 moderate, 201-300 poor, 301-400 very poor and 401-500 severe.
Experts have attributed the improvement in air quality to reduction in local sources of pollution — vehicular emissions, construction dust, stack emissions etc — due to the 21-day lockdown enforced to contain the spread of the coronavirus disease and rains over the last few days.
