However, based on the air quality 124 cities are identified as Non-Attainment Cities (NACs) i.e. those cities exceeding National Ambient Air Quality Standards, consecutively for five years.
The analysis of ambient air quality data of 132 cities indicates that the annual average PM10 concentration in 96 cities showed a decreasing trend and in 36 cities showed an increasing trend in 2020-2021 as compared to 2019-2020. 18 cities were found to be within the prescribed National Ambient Air Quality Standard (PM10 less than 60 µg/m3) in 2019-20 which has increased to 27 in year 2020-21.
