Delhi's air quality remained in the 'very poor' category for the second consecutive day on Tuesday and is likely to worsen further. The government agencies have said that Delhi's air quality is expected to worsen by Wednesday due to slow winds and low ventilation.
Delhi's air quality index (AQI) was recorded at 304 on Tuesday morning, while some areas in the national capital showed the AQI as high as 400. Patparganj in east Delhi recorded AQI 400, as per the Central Pollution Control Board data.
Delhi's air quality index was recorded at 281 on Monday morning and deteriorated to 302 in the evening. It was 274 on Sunday. It was 251 on Saturday, 296 on Friday, 283 on Thursday, and 211 on Wednesday.
The national capital's AQI was in the 'severe' category on November 15, a day after Diwali, but later improved and remained in either 'poor' or 'moderate' category until Sunday.
An AQI between zero and 50 is considered "good", 51 and 100 "satisfactory", 101 and 200 "moderate", 201 and 300 "poor", 301 and 400 "very poor", and 401 and 500 "severe".
Mercury level has also dipped in Delhi, with an IMD forecast of 10 degrees Celsius minimum and 25 degrees Celsius maximum temperature for Tuesday.
Interestingly, the Ministry of Earth Sciences' air quality monitor, Safar, recently said that stubble burning cases in the neighbouring states has significantly decreased to 149.
"Effective stubble fire counts with sufficient potential estimated from SAFAR-multi-satellite products have significantly decreased and are around 149," Safar said.
It further added: "However, stubble burning share in PM2.5 in Delhi's air is estimated as six percent for today, mainly because the calm wind is likely to hold intruded mass for a day."
