Air Pollution, Noise, Blue Space, and Green Spaceand Premature Mortality in Barcelona: A Mega Cohort

Initiatives -
The aim of this study was to evaluate the effects of air pollution, noise, and blue and green space on premature all-cause mortality in Barcelona using a mega cohort approach. Note: All published information has been collected from the article referenced in the Marker Paper box below. Therefore, there may be variations with more advanced versions of the study.

Data Collection Event
We assigned exposure to long term ambient levelsof nitrogen dioxides (NO2), nitrogen oxides (NOx), particulate matter with aerodynamic diameterless than 2.5μm (PM2.5), between 2.5 μm and 10 μm (PM2.5–10, i.e., coarse particulate matter), less than 10μm (PM10) and PM2.5 light absorption (hereafter referred to as PM2.5absorbance) based onland use regressions models. Normalized Difference Vegetation Index (NDVI) was assigned basedon remote sensing data, percentage green space and blue space were calculated based on land usemaps and modelled road traffic noise was available through the strategic noise map for Barcelona.Results:
