| Abstract | This study undertakes a comprehensive analysis of the distribution and health implicationsof particulate matter (PM), with a specific focus on PM2.5, in the urban atmosphere ofBangkok. PM2.5 is a critical concern for both environmental and public health, particularlyin urban settings where sources such as vehicular emissions, fuel combustion, and varioushuman activities are ubiquitous. The research involved the collection of particulate mattersamples at three distinct heights (30, 75, and 110 meters) at the Microclimate and AirPollution Monitoring Station, Faculty of Environment, Kasetsart University. The samplingwas conducted over two periods each day: 8:00 a.m. to 7:00 p.m. (daytime) and 8:00 p.m.to 7:00 a.m. (nighttime). The health impact evaluation, focusing on the inhalation of PM2.5and associated black carbon exposure, revealed a Hazard Quotient (HQ) value of less than1, suggesting no significant non-carcinogenic health effects for both adults and children.However, the assessment highlighted a substantial risk of cancer among children, underscoringthe need for stringent regulatory measures. The average PM2.5 concentrations in the atmosphereexceeded the standard values set by Thai regulatory authorities, with the highest levelsobserved at the 110-meter height. Analysis of the soot-EC to Char-EC ratios indicated thatnear-surface particulate matter is predominantly derived from combustion sources, such asfossil fuels and industrial emissions. This study emphasizes the importance of understandingthe distribution and sources of particulate matter in urban environments to develop effectivestrategies for managing air pollution and mitigating its health impacts. Therefore, policyinterventions should prioritize the reduction of emissions from combustion activities andindustrial processes to enhance the overall air quality and health of the urban population. |
