With the increasing use of paint in urban construction, benzene emissions from painting activities pose significant environmental and public health concerns, particularly in densely built environments. This study quantitatively evaluates benzene dispersion and exposure risks using computational fluid dynamics (CFD) simulations, incorporating seasonal wind patterns, urban morphology, and air circulation dynamics. The results reveal that benzene exposure varies significantly with seasonal airflow conditions, with health risks estimated to be 17.1 times higher in summer due to enhanced dispersion and infiltration, whereas winter conditions lead to prolonged retention in low-ventilation zones, increasing long-term exposure risks. The study highlights the critical role of urban layout and atmospheric dynamics in shaping pollutant dispersion patterns and the necessity for targeted mitigation strategies. Findings advocate adaptive urban planning measures, including strategic zoning regulations, enhanced pollutant dispersion modeling in construction approvals, and dynamic air quality management strategies. This research underscores the need for stricter regulatory frameworks that account for seasonal pollutant variability in urban construction projects to safeguard public health. Future studies should integrate real-time air quality monitoring with CFD-based predictive models to develop proactive environmental control strategies for sustainable urban development.
