As the issues of air quality in Delhi continue, a slight improvement in the air was recorded on Thursday which dropped to the 'very poor category from 'severe' category before.
Delhi had been in the 'severe' air quality category for a past couple of days, health ministers issued statements for people to remain indoors.
There were also high-level of nitrogen dioxide (NO2) across residential areas heightening the toxicity of the haze, reports said.
As per the Air Quality Index (AQI) data, Delhi's Lodhi Road area has prominent pollutant PM 2.5 in "very poor" category.
The air quality did not come in the way of the ongoing test match between India and Sri Lanka at the Feroz Shah Kotla, however, the Lankans wore N95 anti-pollution masks while fielding.
Medics on Monday urged cricket's governing body to revise its rulebook after a Test match between India and Sri Lanka went ahead in the capital despite players vomiting and wheezing for air.
At RK Puram, a densely populated residential area, NO2 was recorded at 135 ug/m3 while levels at ITO, which witnesses heavy volume of traffic, was 206.
During the week, NO2 had climbed to levels as high as 195 at Anand Vihar while the same was 155 and 127 at RK Puram and Dilshad Garden, respectively.
