摘　　要：宣威县是农村肺癌高发区。流行病学调查、毒理学实验、环境污染物的监测等研究已表明肺癌高发的原因与燃煤造成的空气污染有关。为进一步证实这一病因学说,我们对肺癌死亡率高的乡选代表性住户对不同性别的居民进行了个体接触污染物浓度的监测。同时选死亡率低的乡进行对照。监测的项目有:一氧化碳、二氧化硫、氧化氮、甲醛、挥发性有机物、气相及固相多环芳烃及多种无机元素;同时也观察了颗粒物的粒度分布及粒子的外形。结果表明,多环芳烃仍为癌症的主要原因。Xuauwei County is A high incidence area of lung cancer in China. Epidemeological survey, toxicological study and environmental monitoring showed that the cause of high incidence rate of lung cancer was related to the indoor air pollution from coal burning. In order to verify this hypothesis, personal monitoring for indoor air pollutants on residents of different sexes in villages of high incidence was conducted. The TWA concentrations of CO, SO_2, NO_2, formaldehyde, volatile organic compounds, gaseous and particulate polycyclic aromatic hydrocarbons and 27 inorganic elements were determined. The size distribution and shape of airborn particles were also observed. Meanwhile, the same monitoring experiments were also carried out in villages of low incidence for control. 431 data_were obtained. The results showed that the main cause of cancer still is PAH.
