PM2.5 is a particulate matter in the atmosphere that can enter the lungs with a diameter of less than or equal to 2.5 microns. This article discusses the harm of PM2.5 to the human body and the environment and comprehensively introduces the source and mode of PM2.5. Studies have shown that the sources of PM2.5 are divided into natural causes (volcanic ash, pollen ash) and human causes (transportation, agriculture, industry, etc.). This paper reveals that PM2.5 can affect visual visibility and contribute to climate change, exacerbate the greenhouse effect, and cause cardiovascular diseases and negative effects on overall human health. This paper also proposes the treatment methods of PM2.5 in each period from the source, process, and end. Research shows that the treatment technology for PM2.5 is becoming more mature, but there is still room for improvement, such as achieving high efficiency and energy saving of treatment materials, and the integration of existing technologies. People should use a variety of methods to effectively reduce PM2.5 concentration, protect the atmospheric environment, and maintain human public health.
