The city's pollution levels worsened on Wednesday after a slight improvement from wind speeds on Tuesday.
Delhi's air quality deteriorated to the very poor category on Wednesday, as the 24-hour average Air Quality Index (AQI) reached 313, according to The New Indian Express.
The city's average AQI rose from 299 on Tuesday to the current level. Of the 58 monitoring stations reporting data, 34 recorded very poor air quality, 22 were in the poor category, one was severe, and one was moderate.
The Delhi Cantonment monitoring station recorded the lowest AQI at 117, which falls in the moderate range. PM10 was identified as the main pollutant in the capital on Wednesday.
Models from the Indian Institute of Tropical Meteorology (IITM) suggest the transport sector will be the primary source of pollution on Wednesday. However, the impact of stubble burning is projected to rise on Thursday, which could further degrade air quality.
The Air Quality Early Warning System (EWS) has also predicted that concentrations of PM2.5 and PM10 will increase over the next two days.
On Wednesday morning, shallow fog reduced visibility at Safdarjung and Palam airports. At Safdarjung, visibility was 800 metres at 8 am, while Palam recorded 900 metres.
