With an Air Quality Index (AQI) of 361, air quality in Delhi remained in the very poor category on Friday, according to the India Meteorological Department.
An AQI between 201 and 300 is considered poor, 301 and 400 very poor, and 401 and 500 severe.
Minimum temperature in the National Capital settled one notch above the season's normal.
The weather office has predicted shallow fog through the day and a maximum temperature of 25 degrees Celsius.
Delhi’s air quality on Friday was the worst compared to nine other cities monitored on the Central Pollution Control Board’s website.
On Thursday, the Union earth sciences ministry’s monitoring agency System of Air Quality and Weather Forecasting and Research said minimum temperatures have dropped gradually and caused fog during early morning hours, and were likely to lead to a deterioration in AQI.
During afternoons AQI is mainly determined by local winds, maximum temperature/humidity and mixing layer height. Fine particles (size < 2.5 micrometer) contribute ~ 64% to PM10.
An AQI between zero and 50 is considered “good”, 51 and 100 “satisfactory”, 101 and 200 “moderate”, 201 and 300 “poor”, 301 and 400 “very poor”, and 401 and 500 “severe”. AQI in the “very poor” category can lead to respiratory illness on prolonged exposure.
The shallow fog was separately with a minimum temperature of around 8 degrees Celsius and a maximum of 25 degrees Celsius. On Thursday, the minimum temperature was 8.3 degrees Celsius, two notches below normal, and the maximum temperature of 25
The air quality is likely to deteriorate
