The rapid growth of the industries, transportation and urbanization is the main cause of increase in ambient air pollution. Air pollutants ultimately deteriorate the health condition of living beings. The major air pollutants like Nitrous Oxides (NOx), Sulphur dioxide (SO2), Particulate Matter (PM10) especially Particulate Matter (PM) can be considered as invisible carriers. Secondary data were collected and those data demonstrate the fifteen years annual average concentration of SO2, NOx, and Particulate Matter (PM10) in five major locations of the city. The value of RSPM only exceeds the permissible limit of NAAQ. The results show the locations Gandhi market, Central bus stand and Main guard gate are considered highly polluted area and other Golden Rock and Bishop Heber are less polluted areas. Dirty air or air pollutants enter deep into our lungs, can cause respiratory illness like Chronic Obstructive Pulmonary Disease (COPD), asthma and respiratory allergy. This paper is to assess the air quality status of the city and its health impact. Therefore, it is observed that these areas are classified as vulnerable to respiratory diseases.
