"The city's air quality index (AQI) measurement hit 442 on Tuesday morning, according to Swiss air quality firm IQAir. As happens every year, the widespread use of fireworks on Monday evening to mark the festival of lights added to the pollution released in cooler months by traffic, industry and agriculture to make New Delhi the globe's most polluted major city, IQAir said."
"The concentration of PM2.5 tiny airborne particles small enough to enter the lungs and cause serious illness in the city's air on Tuesday morning was more than 59 times the World Health Organization's recommended annual guideline. India's Central Pollution Control Board (CPCB) rated New Delhi's air quality very poor, with an AQI of 350. CPCB considers an AQI of 0-50 as good."
Diwali fireworks added to seasonal pollution in New Delhi, pushing the city's AQI to 442 and making it the most hazardous major city globally. PM2.5 concentrations on Tuesday morning exceeded the World Health Organization's annual guideline by more than 59 times. India's Central Pollution Control Board rated the air quality very poor, recording an AQI of 350 and noting that an AQI of 0-50 is considered good. The Supreme Court permitted limited use of lower-emission "green crackers," but widespread fireworks continued outside allotted times. Forecasts expect air quality to remain Very Poor to Poor in the coming days as winter conditions trap pollutants.
