OBJECTIVE:To investigate the effects of fi ne particulate matter emitted through biomass burning on hospitalizations for respiratory diseases in children living in Manaus, Northern Brazil. METHODS:Descriptive study with ecologic time series design carried out in Manaus from 2002 to 2009. Hospital admission data were obtained from the Unifi ed Health System database. PM 2.5 levels were estimated using aerosol remote sensing through the measurement of aerosol optical depth at a wavelength of 550 nm. Statistical methods were used in the data analysis, with Pearson correlation and multiple linear regression between variables, with a 95% confi dence interval. RESULTS:The region of Manaus showed low PM 2.5 concentrations when compared to the Southern Amazonian region. Between August and November (dry period in the region), was when the highest mean levels of PM 2.5 , estimated between 18 to 23 μg/m³, and the largest number of fi res were observed. For the rainy season, an average of 12 μg/m³, 66% lower than the dry season measurements (20.6 μg/m³) was observed. The highest rates of hospitalization were observed during the rainy season and April was the month with the highest levels at 2.51/1,000 children. A positive association between hospital admissions and relative humidity (R = 0.126; p-value = 0.005) was observed, while the association between admissions and PM 2.5 was negative and statistically signifi cant (R = -0.168; p-value = 0.003). The R² of the fi nal model (Hospitalizations = 2.19*Humidity -1.60*PM 2.5 -0.23*Precipitation) explained 84% of hospitalizations due to respiratory disease in children living in Manaus, considering the independent variables statistically signifi cant (humidity, PM 2.5 , and precipitation). CONCLUSIONS:Hospital admissions for respiratory diseases in children in Manaus, were more related to weather conditions and in particular relative humidity, than to exposure to aerosols emitted by biomass burning in the Amazonian region.

“…In the same region of the study, some authors observed an increase of morbidity and mortality during the same period. They approached that such advance is associated with increase of air pollutants related to the prevalence of biomass burns in the region 16,[29][30][31] . Urban waste burning, which is a common practice in Cuiabá and Várzea Grande, can also contribute to the concentration increase of air pollutants, as well as to their toxicity, because they present more proximity of the individual and have a great mixture of toxic components (plastic, fuel, electronic device) 32 .…”

ABSTRACT:Objective: To identify areas and risk factors in cardiovascular disease (CD) mortality associated with air pollution from high exposure to vehicular traffic. Methods: Cross-sectional study of CD mortality in 2,617 individuals aged 45-85 years living in the urban area of Cuiabá and Várzea Grande, Mato Grosso State, Brazil, between 2009 and 2011. We used the residential proximity of up to 150 meters to a roadway of great vehicle flow as a proxy of high exposure to air pollution from vehicular traffic. The association between age, gender, income, and traffic intensity with vehicular traffic exposure was assessed through the multiple logistic regression. We conducted stratified analyses to observe the influence of seasons and groups of causes. We used Bernoulli's spatial model of probability to identify high-risk clusters. Results: Risk factors for CD mortality associated with high exposure to vehicular traffic were: living in census tracts with very unequal income (OR = 1.78; 95%CI 1.36 -2.33), heavy traffic (OR = 1.20; 95%CI 1.01 -1.43), and female gender (OR = 1.18; 95%CI 1.01 -1.38). The CD mortality risk increases about 10% during the dry season period. We identified nine areas of risk. Conclusion: High exposure to traffic is associated with CD mortality in Cuiabá and Várzea Grande. Income inequality, traffic intensity, and female gender presented as the main determiners for this exposure. The dry season period enhances the effects of traffic exposure.
