Long-term air pollution exposure and Parkinson’s disease mortality in a large pooled European cohort: An ELAPSE study

•We study the association of long-term air pollution exposure with Parkinson’s Disease (PD)•Our study among 271,720 ELAPSE cohort participants noted 381 deaths from PD.•We find that long-term exposure to PM2.5, NO2 and BC are associated with risk of PD death.•Associations persist at low levels of pollutant concentration, below current EU standards.•Our study adds strong evidence in support of an association between air pollution and PD.
