Delhi records season's worst air quality

New Delhi: Two days before Diwali, the national capital's air quality dropped to season's worst on Friday, with the decreased wind speed leading to the accumulation of pollutants and affecting dispersion.

The Supreme Court-mandated Environment Pollution (Prevention and Control) Authority is expected to take a call on Friday on several recommendations made by a 10-member anti-pollution task force.

The recommendations include banning construction work at night in Delhi-NCR from October 26 to 30 and closure of industries that have not switched to piped natural gas.

The city's overall air quality index (AQI) stood at 315 at 8:30 am on Friday, while it was 311 on Thursday evening.
