The air quality in New Delhi, India remains hazardous this week, with experts doubtful of relief soon, according to AFP international news agency.
The extreme smog began last week, prompting school closures, airline flight cancellations, and truck bans, CNN reports. Air Quality Index (AQI) reports reached levels over 1,000, which health experts compared to smoking 44 cigarettes a day. The measure is based on the concentration of fine particulate matter per cubic meter. An AQI over 300 triggers health warnings of emergency conditions.
