This study aimed to explore the potential causal effects of air pollutants on CP and GP. Utilizing genome-wide association study summary statistics from European-ancestry populations, we conducted bidirectional two-sample Mendelian randomization (MR) analyses. Causal estimates were primarily derived through inverse-variance weighted regression, weighted median, MR-Egger, and weighted mode methods to assess pleiotropy and robustness. Multivariable MR (MVMR) further adjusted for smoking and alcohol consumption covariates. MR analyses demonstrated significant causal effects of particulate matter (PM) 2.5 exposure on both CP (OR\u2005=\u20051.060, 95% CI: 1.036\u20131.085,\n                    <jats:italic toggle=\"yes\">P\u2005<\/jats:italic>\n                    =\u20055.51\u2005\u00d7\u200510\n                    <jats:sup>\u221207<\/jats:sup>\n                    ) and GP (OR\u2005=\u20051.031, 95% CI: 1.008\u20131.056,\n                    <jats:italic toggle=\"yes\">P\u2005<\/jats:italic>\n                    =\u2005.008).

Our findings provide novel genetic evidence that long-term PM\u2082.\u2085 exposure independently increases risks of CP and GP, underscoring the need for targeted air quality interventions and public health strategies to mitigate particulate matter-related disease burden.\n
