Development of land use regression, dispersion, and hybrid models for prediction of outdoor air pollution exposure in Barcelona.

Background: Air pollution is the leading environmental risk factor for health. Assessing outdoor air pollution exposure with detailed spatial and temporal variability in urban areas is crucial for evaluating its health effects.

Aim: We developed and compared Land Use Regression (LUR), dispersion (DM), and hybrid (HM) models to estimate outdoor concentrations for NO, PM, black carbon (BC), and PM (Fe, Cu, Zn) in Barcelona.

The association of air pollution and greenness with mortality and life expectancy in Spain: A small-area study.

Background: Air pollution exposure has been associated with an increase in mortality rates, but few studies have focused on life expectancy, and most studies had restricted spatial coverage. A limited body of evidence is also suggestive for a beneficial association between residential exposure to greenness and mortality, but the evidence for such an association with life expectancy is still very scarce.

Objective: To investigate the association of exposure to air pollution and greenness with mortality and life expectancy in Spain.
