Description:
This report presents risk assessment-related aspects of a multidisciplinary study of indoor coal smoke po1lution and lung cancer in Xuan Wei County, Yunnan Province, China. uan Wei presents a unique natural experiment in environmental carcinogenesis because lung cancer mortality rates and indoor pollution exposures vary widely within the County. urrent evidence links lung cancer with domestic burning of "smoky coal", as opposed to "smokeless coal" and wood. fforts to determine the most carcinogenic components of smoky coal pollution are in progress, as are efforts to develop a quantitative relationship of pollution dose with lung cancer response in Xuan Wei. ome available evidence suggests that the composition of indoor pollution does not vary greatly throughout Xuan Wei, and thus that lung cancer risk is a function of overall pollution exposure. ther evidence suggests that different Xuan Wei fuels exhibit different carcinogenic potencies. nsite and laboratory studies are being conducted to extinguish between these possibilities.
