Sector-specific Long-term Associations Between Transportation, Industrial, and Residential Combustion Air Pollutant Mixtures (PM2.5, SO2, NO2, O3) and Neurological Disease-related Mortality in Canada

SSAP mixtures were associated with Alzheimer's disease and dementia mortality in Canada. The direction and magnitude of associations varied by sector and by environmental and sociodemographic context, supporting the value of targeted, sector-specific mitigation strategies to reduce neurodegenerative mortality risk.
