ABSTRACT
This study summarizes the concentration of major gaseous air pollutants in Narsingdi city of Dhaka division. To accomplish this study, we investigate fifteen sampling stations (Velanagar, Railway Station, Boro Bazar, Ghoradia, Brahmondi, Shaheprotap, Launch Terminal, Satirpara, Bus Terminal, Silmandi, Gangpar Bridge, Panchdona, Shekherchar and Anandi) of the study area. In this study, we measured six gaseous air pollutants together with PM2.5 and PM10 during the month of September 2022 using the air quality meter Aeroqual (Series500). The highest concentration of PM2.5 was detected at 58 µg/m3 at Boro Bazar whereas the highest concentration of PM10 was 165 µg/m3 at Anandi of the study area where emissions from vehicles, construction activities and waste burning are predominant. Moreover, in this study, we found a statistically significant correlation with CH4 and CO2 (r = 0.679, p > 0.01), PM2.5 and PM10 (r = 0.630, p > 0.05) indicating their sources of emission might be similar including fossil fuel burning in vehicles, industrial emissions, and road dust. Furthermore, we calculated the AQI value based on PM2.5 concentration, and the highest AQI (152) value was observed in Boro Bazarof the study area followed by Bus Terminal (129), Gangpar Bridge (117), Anandi (112), Ghoradia (102), Brahmondi (89), Panchdona (84), Satirpara (83), Shaherpotap (82), Silmandi (80), Railway Station (78), Madhabdi (78), Shekherchar (76), Launch Terminal (76), Velanagar (59) and was very much compatible with US consulate, Bangladesh published data.
