The rapid acceleration of urbanization and the increasing frequency of climate-driven extreme events have introduced unprecedented complexities into the assessment of human exposure to environmental pollutants. This comprehensive academic paper investigates the spatiotemporal dynamics of air pollution, residential volatile organic compounds, and wildfire-induced particulate matter hazards across diverse microenvironments, specifically focusing on transport cabins and residential sectors within urban communities. Utilizing an extensive array of highly calibrated environmental sensors, spatial mapping techniques, and temporal trend analyses, this research delineates the pathways through which ambient and indoor pollutants accumulate and interact. Transport cabins emerge as distinct microenvironments where localized traffic emissions are concentrated, while residential settings present chronic exposure risks driven by volatile organic compounds originating from synthetic building materials and domestic activities. Furthermore, the exacerbating role of global wildfire events is quantified, revealing systemic vulnerabilities in urban infrastructure when subjected to massive transboundary smoke intrusions. By integrating continuous monitoring data with human mobility patterns, this study provides a high-resolution spatiotemporal framework that substantially reduces the uncertainties inherent in traditional stationary exposure models. The findings offer critical insights for public health authorities, urban planners, and environmental policymakers aiming to mitigate multi-source inhalation risks in an era characterized by escalating environmental volatility.
