Seventeen areas in the national capital recorded serious air quality, says data.
An AQI between 0 and 50 is considered to be “good”, 51 and 100 “satisfactory”, 1
01 and 200 “moderate”, 201 and 300 “poor”, 301 and 400 “very bad” and 401 and 500 “severe” .
The centrifugal airspace and research forecast (SAFAR) system is attributed to “heavy-duty burn in the last 24 hours and calm winds as the cause of the further deterioration of airline capital.
SAFAR said about 28 percent of PM2.5 contamination (presence of particles in the air with a diameter of less than 2.5 microns) on Tuesday was caused by regional factors such as stubble burning.
PM2.5 was recorded at 251, the highest of this season. Fine particles may be a matter of more serious health issues than PM10.
PM10 level (particles in the air with a diameter of less than 10 microns) in Delhi stood at 453, according to CPCB data.
SAFAR said that the contamination is likely to increase further tomorrow and day after and then slow down.
“The air quality index will be in the upper level of very bad for the next three days. The main cause is large biomass burning in the past 24 hours and local calm winds,” says SAFAR.
The Indian Institute of Tropical Meteorology (IITM) also discovered a large number of biomass fires through satellite images in neighboring countries of Delhi.
The prevailing meteorological conditions are less favorable for the spread of pollution over the next two days due to moderate ventilation index and low wind velocity, said it.
“According to Air Quality Forecast, the overall air quality in Delhi is likely to remain close to the top end of very bad category for the next two days,” said IITM.
A thick smudge disaster continued to float over the national capital, the authorities said.
