Aim: To study air quality of Chennai city by comparing the air quality index (AQI) with the National Ambient Air Quality Standard (NAAQS) values.    


Methodology: In urban area, a major straddling problem is air pollution. Analyses was conducted during Jan 2016?Dec 2017 for PM2.5, SO2, NO2 and CO at different seasons in Manali, Chennai. Fine particulate sampler and Lutron CO meter were used to estimate PM2.5 and CO levels.    


Results: Due to different climate changes in India, higher concentration of pollution occurred during summer and monsoon season. The commercial and residential area experienced lower pollution compared with industrial areas. Case-control study showed that the result of odds ratio was significant.    


Interpretation: Commercial and traffic may have significant influence on air quality in Chennai.


Key words: Air Quality Index, Air Pollutants, Epidemiological investigation, Industrial area
