Delhi's air quality plummeted to alarming levels on Tuesday after 24 days, with many areas witnessing a significant spike in pollution despite the strictest measures, including a ban on construction activities and the entry of trucks into the city, coming into force.

The city's 24-hour average Air Quality Index (AQI) was recorded in the 'severe' category with a reading of 433 at 4 pm against 379 on Monday, according to Central Pollution Control Board (CPCB) data.

The last time Delhi's air quality was recorded in the 'severe' category was on November 23, with a reading of 412.

Experts pointed to a significant drop in wind speeds as the primary cause of the sudden spike in pollution, explaining that the lower speed allowed local pollutants to concentrate in the atmosphere.
