Stringent curbs, including a ban on entry of polluting trucks, came into effect in Delhi on Sunday as its air quality entered the “severe plus” category for the second time in three days due to unfavourable wind conditions and a sharp rise in farm fires across north India.

A toxic haze persisted over Delhi-NCR for the sixth consecutive day, causing significant problems for people with respiratory issues.

The 24-hour average Air Quality Index, recorded at 4pm every day, worsened from 415 on Saturday to 454 on Sunday, prompting the Centre to implement all emergency measures mandated under the final Stage IV of its air pollution control plan called the Graded Response Action Plan.

Unfavourable meteorological conditions combined with vehicular emissions, paddy straw burning, firecrackers and other local pollution sources contribute to hazardous air quality levels in Delhi-NCR during the winter every year.

According to a Delhi Pollution Control Committee analysis, the capital experiences peak pollution from November 1 to November 15 when the number of stubble-burning incidents in Punjab and Haryana increases.
