To study air quality of Chennai city by comparing the air quality index (AQI) with the National Ambient Air Quality Standard (NAAQS) values. In urban area, a major straddling problem is air p o l l u t i o n. A n a l y s e s w a s conducted during Jan 2016-Dec 2017 for PM , SO , NO and CO 2.5 2 2 at different seasons in Manali, Chennai. Fine particulate sampler and Lutron CO meter were used to estimate PM and 2.5 CO levels. Due to different climate changes in India, higher concentration of pollution occurred during summer and m o n s o o n s e a s o n. T h e commercial and residential area experienced lower pollution compared with industrial areas. Case-control study showed that the result of odds ratio was significant. Commercial and traffic may have significant influence on air quality in Chennai. Air Quality Index, Air Pollutants, Epidemiological investigation, Industrial area.

“…Recently government agencies easily communicate air quality to the public by displaying AQI values on the digital board at important places in major cities so that people can get some awareness about air quality. Category of AQI and obtained result also reveals moderate air pollution was observed in all the sites except the industrial site and air quality index range is normally maximum in winter shows high air pollution and minimum during monsoon re ects air quality in a satisfactory condition (Saravanakumar et al 2016).…”

The level of air pollution increased in urban areas due to local atmospheric conditions and dispersion of various air pollutants. In this study, the air quality index was carried out in four places in the urban zone and investigated the seasonal variation of PM2.5, PM10, SO2, NO2, and O3 over one year (2021) by considering the meteorological parameters in Coimbatore. Furthermore, fluidyn-PANACHE, a CFD tool, has been used to simulate the dispersion pattern of gaseous pollutants in the selected locations. To track the model, the concentration details of gaseous pollutants were collected and pollutant dispersion under numerous atmospheric conditions (Humidity, Temperature, Pressure) was identified using fluidyn-PANACHE software. From the collected air samples and dispersion pattern, SO2 and O3 show higher concentrations in summer. Particulate matter and NO2 show higher concentrations in winter due to seasonal variations in energy use and atmospheric constancy. Pearson correlation coefficients indicate most pollutants are correlated in Coimbatore except Ozone. Compared to the AQI category given by CPCB, the selected four locations are in the moderate category. However, increased PM10 levels were observed at all the selected zones in winter due to the process of inversion and environmental conditions.

Air is one the major source for all living organisms to sustain on the earth. Nowadays due to heavy traffic and industrial population most of the cities are affected by air pollution. In this research the Marudhamalai Hill Shrine was selected as the study area to monitor the air quality in its vicinity. Marudhamalai is located on the Western Ghats in Coimbatore district. It is famous for the Murugan temple located on it as people from Coimbatore and other parts of India visit every year. From the results it was clear that the forest surrounding the hill shrine not have medicinal plants but these plants help in to maintain the air quality parameters resulting in the quality to be within the prescribed limits.
