Health impact assessment of air pollution in Valladolid, Spain

Objective: to estimate the attributable and targeted avoidable deaths of outdoor air pollution by ambient PM10, PM2.5 and O3 according to specific WHO methodology. Design: health impact assessment. Setting:City of Valladolid, Spain (around 300.000 residents). Data sources: demographics; mortality; pollutant concentrations collected 1999-2008. Main outcome measures: attributable fractions (AFs); attributable and targeted avoidable deaths (ADs; TADs) per year for 1999 – 2008. Results: Higher TADs estimates (shown here) were obtained when assuming as “target” concentrations WHO Air Quality Guidelines instead of Directive 2008/50/EC. ADs are considered relative to pollutant background levels. All-causemortality associated to PM10 (all ages): 52 ADs (95% CI: 39-64); 31 TADs (95% CI: 24 – 39). All-causemortality associated to PM10 (<5 years): 0 ADs (95% CI: 0-1); 0 TADs (95% CI: 0 –1). All-causemortality associated to PM2.5 (> 30 years): 326 ADs (95% CI: 217-422); 231 TADs (95% CI: 153 ...
