If the air quality index is between 201-300, it is categorized as poor and if it is between 301-400, it is considered very poor, indicating health risks for people sensitive to air pollution. This year, it was 192 and fell under the moderate level, but was the highest since 2013.
“Pune’s air quality levels have ranged from moderate to very poor during Diwali. However, it is expected to improve over the next three days with a rise in the minimum temperatures,” SAFAR’s senior programme officer Neha Parkhi said. A dip in minimum temperatures, low wind speed and emissions from fire crackers on Diwali day has pushed up the air quality index, an indicator to measure pollution levels.
