This research aims to apply Geographic Information Systems (GIS) to analyze the impacts of benzene dispersion in Bangkok. The study collected benzene concentration data from four air quality monitoring stations under the Pollution Control Department between 2019 and 2023. The data were analyzed using spatial interpolation and overlay analysis techniques. The results revealed that high-risk areas for benzene exposure were concentrated in industrial zones and high-traffic areas, particularly in Bang Na, Lat Krabang, and Khlong Toei districts. Based on the findings, the study proposed three-tiered spatial mitigation measures: urgent actions in high-risk zones, preventive measures in moderate-risk areas, and monitoring protocols in low-risk zones. The research provides a preliminary framework for developing air quality management policies in Bangkok, emphasizing spatially targeted interventions based on benzene dispersion risks. However, further field implementation and efficacy assessments are required to ensure the proposed measures align with real-world operational contexts.
