00925njm 22002777a 4500 dc Cárdaba Arranz, Mario author Muñoz Moreno, María Fe author Armentia Medina, Alicia author Alonso Capitán, Margarita author Carreras Vaquer, Fernando author Almaraz Gómez, Ana author 2014 To estimate the attributable and targeted avoidable deaths (ADs; TADs) of outdoor air pollution by ambient particulate matter (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; ADs and 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-cause mortality associated to PM10 (all ages): 52 ADs (95%CI 39 to 64); 31 TADs (95%CI 24 to 39). All-cause mortality associated to PM10 (<5 years): 0 ADs (95% CI 0 to 1); 0 TADs (95% CI 0 to 1). All-cause mortality associated to PM2.5 (>30 years): 326 ADs (95% CI 217 to 422); 231 TADs (95% CI 153 to 301). Cardiopulmonary and lung cancer mortality associated to PM2.5 (>30 years): ▸ Cardiopulmonary: 186 ADs (95% CI 74 to 280); 94 TADs (95% CI 36 to 148). ▸ Lung cancer : 51 ADs (95% CI 21 to 73); 27 TADs (95% CI 10 to 41).All-cause, respiratory and cardiovascular mortality associated to O3 (all ages): ▸ All-cause: 52ADs (95% CI 25 to 77) ; 31 TADs (95% CI 15 to 45). ▸ Respiratory: 5ADs (95% CI −2 to 13) ; 3 TADs (95% CI −1 to 8). ▸ Cardiovascular: 30 ADs (95% CI 8 to 51) ; 17 TADs (95% CI 5 to 30). Negative estimates which should be read as zero were obtained when pollutant concentrations were below counterfactuals or assumed risk coefficients were below one. Conclusions: Our estimates suggest a not negligible negative impact on mortality of outdoor air pollution. The implementation of WHO methodology provides critical information to distinguish an improvement range in air pollution control.
