We applied distributed lag non-linear models to assess the associations between air pollution and COPD mortality in 2007\u20132011 in Guangzhou, China and the total COPD mortality fraction attributable to air pollution was calculated as well. We found that an increase of 10\u2009\u03bcg\/m<jats:sup>3<\/jats:sup> in particulate matter with an aerodynamic diameter of 10\u2009\u03bcm or less (PM<jats:sub>10<\/jats:sub>), sulfur dioxide (SO<jats:sub>2<\/jats:sub>) and nitrogen dioxide (NO<jats:sub>2<\/jats:sub>) was associated with a 1.58% (95% confidence interval (CI): 0.12\u20133.06%), 3.45% (95% CI: 1.30\u20135.66%) and 2.35% (95% CI: 0.42\u20134.32%) increase of COPD mortality over a lag of 0\u201315 days, respectively. Greater air pollution effects were observed in the elderly, males and residents with low educational attainment. The results showed 10.91% (95% CI: 1.02\u20139.58%), 12.71% (95% CI: 5.03\u201319.85%) and 13.38% (95% CI: 2.67\u201322.84%) COPD mortality was attributable to current PM<jats:sub>10<\/jats:sub>, SO<jats:sub>2<\/jats:sub> and NO<jats:sub>2<\/jats:sub> exposure, respectively. In conclusion, the associations between air pollution and COPD mortality differed by individual characteristics.
