Association between the incidence of acute respiratory diseases in children and ambient concentrations of SO2, PM10 and chemical elements in fine particles

摘要: Abstract The aim of this study consists investigating the effects SO2, PM10, inorganic chemical elements and black carbon (BC) present in fine particulates on acute outcomes respiratory diseases children up to 12 years age living Brazilian urban area southern hemisphere during winter (2013) summer (2013–2014) months. SO2 PM10 concentration data were obtained from six air quality monitoring stations spatially distributed area. PM2.5 samples collected at same locations with a MiniVol sampler over 24-h period alternating days. components analysed using energy dispersive X-ray fluorescence reflectance techniques. Hospital care admission events due (n = 8,987) coded groups JJ00-JJ99 International Code Diseases (ICD-10) three hospitals (one public two private hospitals). To quantify association disease pollutant concentrations, generalized additive model (GAM) Poisson distribution was applied. results showed greater risk exposure relative 1.28 (95% CI: 1.22–1.34) 1.14 1.09–1.20) day (lag 0). constituents particles highest for Si 1.22 1.15–1.29), S 1.09 1.06–1.12), Ti 1.01–1.17), BC 1.07 1.03–1.11), Se 1.03 0.96–1.10) Ni 0.96–1.10).
