ANALYSIS OF SEASONAL VARIATION AND DISPERSION PATTERN OF AMBIENT AIR POLLUTANTS IN AN URBAN ENVIRONMENT

نویسندگان

چکیده

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