However, due to the rapid economic development in recent years, it has indirectly led to the continuous deterioration of the quality of the atmospheric environment. Effective control of air pollution in environmental engineering is an important measure to improve the ecological environment and the quality of people’s lives. Therefore, this paper combines the main causes and hazards of air pollution to analyze environmental protection measures in-depth.
