Abstract

Researchers have studied meteorological influences on PM2.5 concentration in Dhaka City with limited data and there is a need for further study. This study analyzes time series data (i.e., decadal data: 2013-2022) encompassing the most recent years to better understand long term state of PM2.5 concentration in the air of Dhaka. Specifically, the purpose is to (1) perform statistical analysis on the PM2.5 data while taking into consideration of monthly and seasonal variation of PM2.5 concentration and compare the mean values with the local and international ambient air quality standards to understand the health effects of PM2.5 concentration in the air, and (2) assess the influences of seasonally varied meteorological parameters (i.e. temperature, relative humidity, precipitation and wind speed) on the concentration of PM2.5. This study utilizes PM2.5 concentration data of the Continuous Air Quality Monitoring Station #3 (CAMS #3-Darus-salam) and meteorological data of Bangladesh Meteorological Department (BMD). It is found that PM2.5 (annual averaging values) has been remained in the air at a very high concentration throughout the ten-year (2013-2022) analysis period causing serious public health hazard and premature deaths. Regarding the influence of meteorological parameters on PM2.5, it is found that all three parameter values (i.e. temperature, relative humidity, and precipitation) are inversely (negatively) correlated with the PM2.5 values, and the meteorological factors including the wind effect (i.e., potential for transporting of PM2.5 from nearby Brick Kilns) may play significant roles in the increment of PM2.5 concentration during the Dry season.
