Delhi records lower PM 2.5 levels on the day after Diwali, but it continues to be above safe limits
Each year, air pollution levels spike in the Indo-Gangetic Plain on the day after Diwali with grey skies and hard-to-breathe air. This results from several meteorological factors, the stubble burning in neighbouring states and increased local emissions due to the firecracker use. Analysis by the NCAP Tracker of data from CPCB’s 33 monitors in Delhi showed that PM 2.5 levels in the capital city this year were lower than in 2021 but continued to be above the daily safe limits of 60 ug/m3. Data for four monitors was missing and hence has been excluded from the analysis. The highest PM 2.5 levels of 448.8 ug/m3 in the city were recorded at Pusa, Delhi.
