Abstract

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 PM_2.5 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
