The environment of a city is a critical determinant of the health of its inhabitants and consequently, urban productivity. Here the annual pollutants (SO2, NOx, SPM, RSPM) have been taken to express the pollution levels in the city.

Overall Level of Service (LoS) for Pollution level City-wide
Calculated LoS = (LoS1 + LoS2 + LoS3 + LoS4) and identify overall LoS as mentioned below
