NDTV
The PM 2.5 pollution rose above the 500 micrograms/cubic metre mark in Delhi. One location in the capital saw PM 2.5 rise above 500, while two areas were only slightly below 500.
A thick blanket of toxic haze enveloped Delhi for the second consecutive day as the air quality deteriorated to the "severe plus" category today, prompting the AAP-led Delhi government to shut primary schools for two days.
Delhi's 24-hour average air quality index stood at 468 on Friday which falls in the "severe plus" category, a stage at which all emergency measures, including a ban on polluting trucks, commercial four-wheelers, and all types of construction, are mandated to be initiated and enforced in the National Capital Region.
According to an analysis by Respirer Reports, a part of Respirer Living Sciences, the level of PM 2.5, Particulate Matter (PM) with less than 2.5 micrometres in diameter, crossed the 600 micrograms/cubic metre mark in at least six places while the average PM 2.5 level was lower.
