Delhi's air quality in May this year was the poorest for the month in the last three years, according to the Central Pollution Control Board data.
Experts attributed the poor air quality to the lack of rainfall in the first half of the month.
The city received just 1.4 mm of rainfall from May 1 to May 20, according to the India Meteorological Department.
Delhi recorded an average air quality index (AQI) of 212 this year as against 144 in 2021 and 143 in 2020.
It saw 21 days of "poor" air quality in 2022 as compared to three in 2021 and just two in 2020.
The capital had only one day of "satisfactory" air quality this time as against six in 2021 and four in 2020.
"Moderate" air quality days also dipped to nine as compared to 22 such days last year.
An AQI between 201 and 300 is considered 'poor', 301-400 'very poor' and 401-500 'severe', while the AQI above 500 falls in the 'severe plus' category.

In a bid to tackle one of the worst sources of air pollution, Delhi has begun testing retrofitting devices that promise to cut harmful emissions from heavy commercial vehicles by more than 70 per cent.
Delhi is gearing up to build one of India's most advanced e-waste processing facilities, and it's taking cues from Norway's cutting-edge model.
The national capital on Sunday recorded a maximum temperature of 33.6 degrees Celsius, 7.8 notches below the seasonal average, according to the India Meteorological Department (IMD).
Air Quality Management Commission admitted it has not conducted any research or study on pollution caused by diesel vehicles older than 10 years and petrol vehicles older than 15 years, which form the basis of the overage vehicle ban in Delhi-NCR.

Opinion | Why Indians Have Just Given Up On Air Pollution CrisisTanushree Ganguly
Friday December 20, 2024While some may argue that people in Delhi are now more aware of air pollution than they were a decade back, my rebuttal would be that awareness does not mean that people are concerned.

Tuesday December 10, 2024Delhi welcomed us with monsoon rains and mangos. We were home. Fast forward a couple of years, in the winter of 2012, I found myself in denial about something other parents, mostly expats, were calling toxic air.

Friday November 22, 2024On a good day, such as today, the AQI reading in Delhi is 407. We are jubilant at the sickly sunshine trickling through the slightly dissipated smog. At least its not 1600.

घर में कैद बुजुर्ग और हांफते लोग, दिल्ली की सांसों में घुला ये कैसा रोग?Nidhi Kulpati
Friday November 08, 2024हमारी हवा जहरीली हो रही है. गुरुवार की शाम को जब मैं इस मुद्दे पर लिखने बैठी तो AQI लगातार 400 पार जाकर दम घोंट रहा था. बहुत लोगों को यह मामला बोरिंग लगे, लेकिन जब आप अपने साथ काम करने वालों को खांसते-हांफते देखते-सुनते हैं, तो चिंता होने लगती है. सुबह उठते ही दरवाजे खिड़कियां खोलने के लिए डॉक्टर मना कर रहे हैं. बड़े बुजुर्गों के लिए तो मॉर्निंग वॉक बाहर की दुनिया से सीधे संपर्क का ज़रिया है, लेकिन डॉक्टर इसकी भी मनाही कर रहे हैं.
