【 摘 要 】

The Xuanwei area of Yunnan Province in China has been the high incidence area of lung cancer and mortality worldwide since 1980s. The high incidence factors of lung cancer in Xuanwei area were studied in epidemiology, atmospheric science and molecular biology. We believed that the high incidence of lung cancer was not a single factor but the result of the interaction of many high risk factors, such as the use of coal and indoor air pollution may be a cause of high incidence of lung cancer in Xuanwei. However, the risk factors of stove type, life habits and so on need to be further studied. This paper mainly analyzed the causes of high incidence of lung cancer from two aspects: fine particles produced by coal combustion and polycyclic aromatic hydrocarbons (PAHs) in Xuanwei area. We concluded that the form of Fe+ in the bituminous coal was helpful for the emission of PAHs, and the PAHs on the surface of fine particles bring lung health risks.
