Despite the known link between air pollution and cause-specific mortality, its relation to chronic kidney disease (CKD)-associated mortality is understudied. Therefore, we investigated the association between long-term exposure to air pollution and CKD-related mortality in a large multicentre population-based European cohort. Cohort data were linked to local mortality registry data. CKD-death was defined as ICD10 codes N18–N19 or corresponding ICD9 codes. Mean annual exposure at participant's home address was determined with fine spatial resolution exposure models for nitrogen dioxide (NO₂), black carbon (BC), ozone (O₃), particulate matter ≤2.5 μm (PM_2.5) and several elemental constituents of PM_2.5. Cox regression models were adjusted for age, sex, cohort, calendar year of recruitment, smoking status, marital status, employment status and neighbourhood mean income. Over a mean follow-up time of 20.4 years, 313 of 289,564 persons died from CKD. Associations were positive for PM_2.5 (hazard ratio (HR) with 95% confidence interval (CI) of 1.31 (1.03–1.66) per 5 μg/m³, BC (1.26 (1.03–1.53) per 0.5 × 10^{− 5}/m), NO₂ (1.13 (0.93–1.38) per 10 μg/m³) and inverse for O₃ (0.71 (0.54–0.93) per 10 μg/m³). Results were robust to further covariate adjustment. Exclusion of the largest sub-cohort contributing 226 cases, led to null associations. Among the elemental constituents, Cu, Fe, K, Ni, S and Zn, representing different sources including traffic, biomass and oil burning and secondary pollutants, were associated with CKD-related mortality. In conclusion, our results suggest an association between air pollution from different sources and CKD-related mortality.
