Abstract: Through the analysis and comparison of meteorological data and seasonal fluctuations in air pollutants, this study investigated the quality of the air in Dhaka. All around the nation, there is a lot of rainfall during the rainy season. Rivers, canals, marshes, and low-lying regions around Dhaka city are now under water. Compared to the dry season, the wind speed is stronger during this period. Rain removes pollutants from the air, particularly particle matter. As a result, there are fewer PM 2.5 and PM 10 pollutants than during the dry season. For the last five years, from January 2016 to December 2020, Darussalam's air pollution concentrations and seasonal variations have been recorded. Owing to time and resource limitations, an evaluation of Dhaka's air quality has been conducted using secondary data gathered by the Department of Environment (DoE), the Bangladesh Agricultural Research Council (BARC), the Continuous Air Monitoring Station (CAMS), the Air Quality Management Project (AQMP), and various government agencies and institutions as well as published research studies. The main pollutants' daily emissions as well as the contributions of exhaust emissions from the various cars operating in Dhaka will be measured. To evaluate the health impacts and establish relationships, the survey will be conducted among those most impacted by roadside pollution, particularly traffic police officers. To illustrate variations in air pollution and meteorological data, the Pearson correlation coefficient test was created using Origin Pro and shown statistical analysis in SPSS. The majority of air pollutant concentrations were shown to have a negative connection with temperature, precipitation, and relative humidity, according to the correlation metrics. Although particulate matter (PM2.5 and PM10) has a strong negative association with temperature and relative humidity, it has a positive correlation with other gaseous pollutants (SO2, NO2, CO, and O3). Pollutants and temperature often have a negative relationship. To make decisions about control strategies to preserve Dhaka's atmospheric environment and take appropriate action to reduce health hazards for the most endangered group exposed to air pollution, this study will give environmentalists, urban planners, traffic engineering practitioners, and policymakers the right management and technological tools.
