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(pm2 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.
