In Xuanwei County, Yunnan Province, lung cancer mortality is among China's highest, especially in females. (Cigarette smoking is rare in females). The country has 20 communes, each with a population of about 30,000 to 60,000. Lung cancer mortality is varied in the country from 0 to 151.8/10,000. Xuanwei residents use three fuels: (1) smoky coal, (2) wood, and (3) smokeless coal. Because of heavy indoor pollution caused by smoky coal burning, in 1986, we developed a risk assessment by measuring B(a)P concentrations in the indoor smoke caused by fuel burning in 11 communes. Our results showed that the lung cancer mortality was increased with the B(a)P concentrations in indoor air. There was an obvious exposure-response relationship between B(a)P concentrations in indoor air and lung cancer mortality rates. From the strong exposure-response relationship between B(a)P concentrations in indoor air and lung cancer mortality rates, we conclude that the B(a)P concentration indicates that the PAH pollution caused by smoky coal burning is the main risk factor of lung cancer in Xuanwei County.
