Abstract
The increased occurrence of smoggy days in major Chinese cities is of major concern to the general public. This paper explores the major sources of PM 2.5 pollutants, a key contributor to the smog in Beijing, one of China’s largest cities. Evidence indicates that the secondary PM 2.5 particles formed through NO x , SO x , NH 3 , VOCs, etc. have a strong impact on human health. As a result, PM 2.5 pollution control should not simply focus on controlling particulate emission, but should involve adopting an integrated multi-pollutant control strategy. In addition to identifying the major sources of PM 2.5 , this paper explores its impact on environmental and human health. Although the intention of this research is not to provide solutions for reducing PM 2.5 pollution, the paper analyzes the United States ’ experience with establishing PM 2.5 standards and mandates. Specifically, this paper focuses on the air quality control strategies adopted in California since the 1940s and draws parallels with present-day China. The research suggests that adequate government regulation, public awareness, regional collaboration and industrial compliance are keys to successfully controlling PM 2.5 pollution.
