Abstract
The atmosphere surrounding Bangladesh is being polluted day by day in short order due to harmful activities strongly related to air pollution. This study was carried out in Khulna City of Bangladesh located in the southern part of the country. Gaseous air pollutants concentrations at specific eight locations were measured and analysed using real-time monitoring equipment. Time series analysis, diurnal and seasonal variations in mass concentration and variation in total mass concentration of SO2, CO, and NOx were analysed. This study reveals the highest average concentrations of SO2, CO, and NOx as 224 μg/m3, 3,104 μg/m3, and 116 μg/m3 consecutively. Significant diurnal and seasonal variation of pollutants can be sanctioned by the adjustable working scenario of concerning locations. Air pollution controlling provisions can be directed considering this baseline study in Bangladesh and other similar Asian countries.
