Air pollution and lung cancer are closely related. In 2013, the World Health Organization listed outdoor air pollution as carcinogenic and regarded it as the most widespread carcinogen that humans are currently exposed to. Here, grey correlation and data envelopment analysis methods are used to determine the pollution factors causing lung cancer among residents in Nanchang, China, and identify population segments which are more susceptible to air pollution. This study shows that particulate matter with particle sizes below 10 micron (PM) is most closely related to the incidence of lung cancer among air pollution factors including annual mean concentrations of SO₂, NO₂, PM, annual haze days, and annual mean Air Pollution Index/Air Quality Index (API/AQI). Air pollution has a greater impact on urban inhabitants as compared to rural inhabitants. When gender differences are considered, women are more likely to develop lung cancer due to air pollution. Smokers are more likely to suffer from lung cancer. These results provide a reference for the government to formulate policies to reduce air pollutant emissions and strengthen anti-smoking measures.
空气污染与肺癌密切相关。2013年，世界卫生组织将室外空气污染列为致癌物，并将其视为人类目前接触到的最广泛的致癌物。在此，运用灰色关联和数据包络分析方法来确定中国南昌居民中导致肺癌的污染因素，并识别出更容易受到空气污染影响的人群细分。本研究表明，在包括二氧化硫（SO₂）、二氧化氮（NO₂）、颗粒物（PM）的年均浓度、年雾霾天数以及年均空气污染指数/空气质量指数（API/AQI）等空气污染因素中，粒径小于10微米的颗粒物（PM）与肺癌发病率关系最为密切。与农村居民相比，空气污染对城市居民的影响更大。考虑性别差异时，女性因空气污染患肺癌的可能性更大。吸烟者患肺癌的可能性更大。这些结果为政府制定减少空气污染物排放的政策以及加强禁烟措施提供了参考。
