In recent years, with the rapid development of China's industry and the high consumption of energy, air pollution has become one of the worrying environmental problems. The haze phenomenon has become increasingly serious, and the pollution of Pm^2.5, the most important pathogenic substance in smog, has become a serious environmental problem in China. Pm^2.5 causes respiratory diseases through inflammatory reactions, oxidative stress, induced autophagy, and apoptosis. The child is in the growth stage and is one of the highly sensitive people in Pm^2.5. Pm^2.5 can enter the child's trachea and even the lungs with breathing, leading to an increase in the incidence of respiratory diseases such as lower respiratory tract infections, asthma, rhinitis, and tuberculosis. However, there is no good solution to completely eliminate the harm caused by Pm^2.5. In the future, more research is needed to further verify the pathogenic mechanism of Pm^2.5 and its relationship with respiratory diseases in children, and to develop effective preventive measures. And treatment options. This article reviews the sources and characteristics of Pm^2.5, the pathogenesis and effects on children's respiratory related diseases, and aims to provide reference for clinical research.
