Air pollution and mortality in Valencia, Spain: a study using the APHEA methodology.

摘要: STUDY OBJECTIVE: To assess the short term relationship between daily air pollution indicators (black smoke and sulphur dioxide (SO2)) mortality in Valencia. DESIGN: This was an ecological study using time series data with application of Poisson regression. Daily variations four selected outcome variables (total mortality, those over 70 years age, cardiovascular respiratory mortality) were considered relation to levels for period 1991-93. SETTING: The city Valencia, Spain. MAIN RESULTS: mean 17.5, average pollutants from three monitoring stations included were, 67.7 micrograms/m3 black smoke, 39.9 micrograms/ m3 SO2. A significant positive association outcomes found. estimated relative risk (RR) dying corresponding a 10 increase whole 1.009 (95% confidence interval CI): 1.003, 1.015). For group aged more than RRs 1.008 CI: 1.001, 1.016) 1.012 1.022) respectively. SO2 less clear: it only evident during warm season. this case 1.007 0.999, 1.015) total 1.00, 1.21) older 70, 0.995, 1.026) deaths. No found diseases either two pollutants. CONCLUSIONS: term, as has been shown important number studies carried out elsewhere. Although current particulate Valencia are not very high, they could have effect on premature Despite fact that is weak, at public health level both because numbers population exposed possibility establishing control measures.
