Understanding the latest global spatio-temporal pattern of lung cancer burden attributable to ambient fine particulate matter pollution (PM₂.₅) is crucial to prioritize global lung cancer prevention, as well as environment improvement. Data on lung cancer attributable to ambient PM₂.₅ were downloaded from the Global Burden of Disease Study (GBD) 2019. The numbers and age-standardized rates on lung cancer mortality (ASMR) and disability-adjusted life years (ASDR) were estimated by age, sex, region, and country. We used estimated annual percentage change (EAPC) to quantify the temporal trends of ASMR and ASDR from 1990 to 2019. In 2019, the number of global lung cancer deaths and DALYs attributable to ambient PM₂.₅ was approximately 0.31 million and 7.02 million respectively, among which more deaths and DALYs occurred in males. At GBD region level, the heaviest burden occurred in East Asia, accounting for over 50% worldwide, with China ranked first worldwide. The number of ambient PM₂.₅ attributable lung cancer deaths and DALYs has over doubled from 1990 to 2019, but high sociodemographic index (SDI) region had a rapid decrease, with EAPC -2.21 in ASMR (95% CI: −2.32, −2.09). The age-specific mortality rate or DALY rate has increased in all age groups in low to middle SDI regions from 1990 to 2019. The ASMR or ASDR showed an inverted V-shaped association with SDI. The EAPC in ASMR or ASDR was highly negatively correlated with ASMR or ASDR in 1990 and SDI in 2019, with coefficients around 0.70. The number of ambient PM₂.₅-related lung cancer deaths and DALYs has largely increased because of the increase of exposure to PM₂.₅, population growth, and aging. Local governments should do economic activities under the consideration of public health, especially in high-burden areas.
