Delhi Air Quality
Delhi’s 24-hour average AQI was 256 at 4 pm on Thursday, 243 on Wednesday and 220 on Tuesday.
According to the Centre’s Air Quality Early Warning System for Delhi, the city’s air quality is likely to deteriorate to ‘very poor’ category on Saturday.
Air Quality Likely To Deteriorate
Unfavourable meteorological conditions and a cocktail of emissions from firecrackers and paddy straw burning, in addition to local sources of pollution, push Delhi-NCR’s air quality to hazardous levels around Diwali every year.
