自从1971年以来,广州市肺癌死亡率迅速增加,而且迅速增加的趋势仍在持续。对于肺癌有关的各种因素,如香烟销售量、生活用煤量、工业用煤量、汽油销售量、大气污染物浓度,以及人口密度进行分析,提示生活用煤占有最重要地位。为了进一步探讨致肺癌因素,进行了室内空气污染调查和病例配对研究。结果表明室内空气污染十分明显,妇女接受煤烟影响而患肺癌的相对危险度还略高于吸烟因素,但男性吸烟的相对危险度高达5.6。 Since 1971, the lung cancer death rate in Guangzhou has rapidly increased, and the trend of rapid increase is still continuing. Various factors related to lung cancer, such as cigarette sales, domestic coal consumption, industrial coal consumption, gasoline sales, air pollutant concentrations, and population densities, suggest that domestic coal occupies the most important position. In order to further explore the causes of lung cancer, indoor air pollution investigation and case matching studies were conducted. The results show that indoor air pollution is very obvious, women’s relative risk of suffering from lung cancer is still slightly higher than smoking, but the relative risk of smoking in men is as high as 5.6.
