Research advances in the mechanism of respiratory injury induced by PM_2.5

As an important air pollutant, fine particulate matter(PM_2.5) can cause respiratory injury by inducing inflammatory response and oxidative stress. This article reviews the effects of PM_2.5 on chronic respiratory diseases and the mechanisms of respiratory injury caused by PM_2.5, and puts forward intervention suggestions to protect these injuries, hoping to provide reference for related research on the health effects of PM_2.5 and health protection in the future.
