Abstract: With the acceleration of urbanization, high-rise housing has become the mainstream form of living, and the diffusion of kitchen soot particles poses a serious threat to indoor air quality and residents’ health. The physicochemical properties, diffusion mechanism and health risk assessment methods of cooking fume particles in high-rise residential kitchens are systematically reviewed, and the pollutant propagation law in the special environment of high-rise buildings is analyzed, and the optimization path and future trend of ventilation control technology are prospected. The results show that the thermal plume effect of soot particles (pm_2.5/ufps) is dominant, and the chimney effect aggravates the cross household transmission in high-rise residential buildings; The design of air supplement system and the optimization of smoke exhaust duct structure are the key to control pollutant concentration; In the future, it is necessary to integrate intelligent monitoring, green materials and interdisciplinary research to build a healthy and safe kitchen environment.

Key words: High-rise residences, Kitchen space morphology, Cooking pollutants, Diffusion pattern
