Note:- R – Residential and other areas, I – Industrial area, Std deviation – Standard deviation,

n – number of days monitored for 16 and more hours a day

L- Low, M- Moderate, H – High and C – Critical levels of pollution based on exceedence factor

BDL = Below Detection Limit (Concentration less than 4 mg/m3 for SO2)
BDL = Below Detection Limit (Concentration less than 9 mg/m3 for NO2)
