The Situation and Prediction of Air PM2.5 Pollution in Shanghai

In the field of environmental science, fine particulate matter (PM2.5) has attracted much attention due to its significant impact on public health. These particles with a diameter of less than or equal to 2.5 microns can carry various harmful substances, penetrate the defense line of the respiratory tract into the deep lungs, and even enter the circulatory system, thereby increasing the risk of cardiovascular and cerebrovascular diseases, respiratory diseases, and cancer. With the acceleration of industrialization and the increase of urban activities, the pollution problem of PM2.5 is becoming increasingly severe, bringing huge challenges to public health management and environmental protection. Therefore, in-depth research on the sources, components, distribution characteristics, and human health impacts of PM2.5 not only has important value in environmental science research, but also has urgent practical significance for formulating effective prevention and control strategies and improving people's quality of life. The article will mainly discuss about these things that mentioned above.
