Epidemiological Study on the Impact of Urban Air Pollution on Residents' Respiratory Health

With the rapid advancement of industrialization and urbanization, urban air pollution has become a global environmental problem, posing a serious threat to the respiratory health of residents. This study explored the relationship between urban air pollution and residents' respiratory health through epidemiological methods. Through the comprehensive analysis of air quality monitoring data, residents' health records and hospital respiratory disease incidence records in several cities, we found that there was a significant correlation between the increase of air pollution concentration and the increase of respiratory disease incidence rate. Especially suspended particulate matter (such as PM2.5), sulfur dioxide and other pollutants pose a particularly prominent threat to respiratory health. These pollutants mainly have a negative impact on the respiratory system by stimulating the respiratory tract, triggering inflammatory reactions, and damaging lung tissue. In addition, susceptible populations such as the elderly and children are more sensitive to air pollution, and their respiratory health is more severely affected.
