Time Series Analysis PM2•5 Concentration for Capital City Dhaka from 2016 to 2023

Dhaka, as the epicenter of economic, political, and cultural activity, has been actively pursuing urbanization, modernization, and development in line with global trends. The rise in unplanned urbanization, industrialization, and other human activities have led to an escalation in air pollution levels. The quality of air in Dhaka is progressively declining over time. It has become a significant challenge due to its detrimental effects on both human health and the environment. The objectives of the study to analyze the air quality in Dhaka city over eight years, from 2016 to 2023 and to assess the relation between concentration of PM2•5 and meteorological characteristics in Dhaka city. AQI and PM2•5 data has been collected from the website of U.S. Embassy Dhaka and meteorological data from the Bangladesh Meteorological Department (BMD). Data processing and analysis have been conducted by using SPSS and Microsoft Excel. Annual variations indicated that 2023 experienced the highest air pollution levels with an average PM2•5 concentration of 103.67 µg/m³ which is 2.96 times higher than the national ambient air quality standards level. Furthermore, shifting variation analysis demonstrated that air quality deteriorated in the night to morning, reaching an unhealthy level, largely attributed to heavy traffic. Along with that seasonal variations illustrate that winter had the highest PM2•5 levels where monsoon had lower, linked to factors like biomass burning and reduced rainfall. This variance is due to the interaction of a number of different meteorological phenomena. Moreover, Weekly variations showed Thursday to have the highest air pollution. The percentage of “Good” days is very poor and with that "Unhealthy" and "Very Unhealthy" AQI categories significantly increased, posing a serious threat to public health. To address this, a range of short, mid, and long-term strategies are recommended, including improved public awareness, sustainable constructions and transportation options, and stricter environmental regulations.
