Note:

24 hours average concentrations of parameters viz. Nitrogen dioxide (NO₂₎, and Sulphur dioxide (SO₂) are below the permissible limits of National Environmental Quality Standards (NEQS) whereas concentration of Particulate Matter of size less than 2.5 microns (PM_2.5) is higher than safe limit of NEQS.
