The air quality in Chennai, Tamil Nadu, deteriorated sharply this week, with the Air Quality Index (AQI) downgrading air quality in the city from ‘satisfactory’ on Tuesday to ‘poor’ on Wednesday and ‘very poor’ on Thursday.

The AQI in Chennai on Wednesday, the day the city celebrated Deepavali, was ‘poor’, with an index value of 263, which rose to ‘very poor’ (302) at 4 pm on Thursday — AQI in New Delhi was nearly the same at 319, according to the Central Pollution Control Board. On Tuesday, a day before Deepavali, Chennai had recorded ‘satisfactory’ (66) air quality. The six-scale AQI index rates air quality from ‘good’ (minimal impact) to ‘severe’ (affects healthy people and seriously impacts those with existing diseases). At 2.5 million, India tops list of pollution-linked deaths: Study

Air pollution in other cities across the country also recorded a significant increase. Kolkata at 358, Agra at 332 and Faridabad at 309. The recordings fall under the ‘very poor’ category.

A day before Deepavali, the Tamil Nadu Pollution Control Board had appealed to residents of the city to “restrict” bursting crackers to the “maximum extent possible”, considering weather conditions were “not conducive”, reported PTI. Several parts of the city had been receiving rainfall, while other parts were witnessing cloudy skies.

In a statement, the board said: “In view of the prevailing climatic condition and weather forecast made for the next two days, it is obvious that the conditions are not conducive for normal dispersion of smoke and particulate matter in view of possible inversion.”
