With the development of modern industry, air pollution is worsening and people are increasingly concerned about the quality of the air. The United States amended the Clean Air Act in 1963 to set up legislative tools to improve and maintain air quality. This reflects the importance the U.S. government attaches to air quality. However, does forest fire cause air pollution? This issue is controversial in the scientific community. In order to scientifically explain the impact of forest fire on the air quality, many scientists have conducted a study, these studies are mainly from the following aspects: 1. The composition of the smoke Smoke from the forest fire components are determined by the burning of combustibles, forest combustibles include
