Delhi’s air quality sinks to ‘very poor’

A day after Diwali, the air quality of the national Capital on Friday deteriorated to “very poor” category with the air quality index crossing the 600 mark at several locations across Delhi, while Ghaziabad and Noida crossed 800 mark in morning hours.

According to the latest update by System of Air Quality and Weather Forecasting And Research (SAFAR), the air quality in several areas in Delhi was recorded in the “very poor” category with AQI ranging around 400.

The air quality in Delhi was recorded in the “hazardous” category at Janpath in the city early on Friday. The particulate matter (PM) 2.5 concentration was recorded at 655.07 in Janpath on Friday morning, according to news agency ANI. As per Government standards, PM 2.5 concentrations over 380 are marked as “severe.”

While as per SAFAR model the share of stubble emissions has peaked 36 per cent,  in last 24 hours values of Particulate Matter ( PM ) 2.5 recorded higher as compared to post Diwali day of last year.

RK Jenamani, IMD Delhi said, “Overall air quality in ‘severe’ category today after bursting for firecrackers on Diwali and presence of bio-mass pollutants in Delhi. The air quality and fog condition to improve once wind speed picks up. No wind and high moisture is causing fog conditions.”

Extremely poor pollution levels were previously predicted in Delhi due to firecracker emissions, unfavourable weather and a significant spike in stubble burning in neighbouring States.

SAFAR in its short range weather forecast said “very calm” local Delhi wind conditions with little ventilation is expected for the next three days which will be unfavourable for dispersion of pollutants. Delhi’s PM2.5 concentration is predicted to be in the upper end of the “very poor” category till November 6.
