In April, Delhi experienced the highest number of ‘good to moderate’ air quality days since 2018, with only seven days surpassing an AQI of 200 this year.
This improvement comes in contrast to 2020, when pollution levels plummeted due to the strict lockdown amid the Covid pandemic. According to the Centre’s Commission for Air Quality Management, there were 13 such days in 2023, 30 in 2022, 12 in 2021, 18 in 2019, and 22 in 2018.
The average AQI in Delhi for April 2024 stood at 182, marking the second lowest figure in the past seven years. This compares to 180 in 2023, 255 in 2022, 202 in 2021, 110 in 2020, 211 in 2019, and 222 in 2018.
The CAQM reported a significant decrease in the daily average concentrations of PM2.5 and PM10 compared to previous years for the same period. (With inputs from PTI)
