“…2 Although standards of Brazilian air quality for PM 2.5 are studied, Brazilian legislation only contains maximum values for PM 10. Links with hospital admissions proved to be significant when grouped by week, with a greater number of environmental variables, compared to when grouped Many studies have found adverse effects referring to climatic effects and pollutants on respiratory morbidity, depending on the region studied, the sources of the emissions, the model of hospital management and number of beds available for respiratory disease, among other factors. 1,4 Results of recent studies in the Brazilian Amazon have behaved in a similar was: frequency and rates of morbidity due to respiratory disease were relatively related to certain concentrations of particulate material, 13 to periods of low air humidity and to burning in the region. 7,18 The time series of the hospital admissions in Manaus showed seasonal behavior clearly associated with air humidity (Figure 2b).…”

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.

“…Some papers have discussed the impact on human health of the pollutants from wood smoke, and, more recently, sugarcane smoke. 5,15 In the case of the Amazon region population, it is important to note that during the rainy season there is no air pollution, except some biogenic particles in the atmosphere. 18 On the other hand, the studies on air pollution in conjunction with the sugarcane harvest were conducted in southeastern Brazil, which has also many industries and a lot of vehicles, thus resulting in some air pollution at all times of the year.…”

“…Consequently, it can be assumed that exposure to the smoke from biomass burning probably produces intensities of effects that differ from exposure to urban air pollution. 15 In fact, values as high as 400 μg/m³ of PM 10 have been reported in some areas of the Amazon region during the dry season. 3,4 The Amazon region encompasses an area of about 5 million km 2 with an estimated population of 24 million inhabitants, distributed among more than 805 municipalities, which make up a total of 107 microregions.…”

Impact on human health of particulate matter emitted from burnings in the Brazilian Amazon regionImpactos na saúde humana de partículas emitidas por queimadas na Amazônia brasileira ABSTRACT OBJECTIVE: To analyze the impact on human health of exposure to particulate matter emitted from burnings in the Brazilian Amazon region. METHODS:This was an ecological study using an environmental exposure indicator presented as the percentage of annual hours (AH%) of PM 2.5 above 80 μg/m 3 . The outcome variables were the rates of hospitalization due to respiratory disease among children, the elderly and the intermediate age group, and due to childbirth. Data were obtained from the National Space Research Institute and the Ministry of Health for all of the microregions of the Brazilian Amazon region, for the years 2004 and 2005. Multiple regression models for the outcome variables in relation to the predictive variable AH% of PM 2.5 above 80 μg/m 3 were analyzed. The Human Development Index (HDI) and mean number of complete blood counts per 100 inhabitants in the Brazilian Amazon region were the control variables in the regression analyses. RESULTS:The association of the exposure indicator (AH%) was higher for the elderly than for other age groups (β = 0.10). For each 1% increase in the exposure indicator there was an increase of 8% in child hospitalization, 10% in hospitalization of the elderly, and 5% for the intermediate age group, even after controlling for HDI and mean number of complete blood counts. No association was found between the AH% and hospitalization due to childbirth. CONCLUSIONS:The indicator of atmospheric pollution showed an association with occurrences of respiratory diseases in the Brazilian Amazon region, especially in the more vulnerable age groups. This indicator may be used to assess the effects of forest burning on human health.

“…There seems to be enough evidence that in situations of increased concentrations of PM 2.5 , as observed in the Amazon region due to biomass burning, there is an increase in hospitalization of children and the elderly with respiratory diseases (IGNOTTI et al, 2007(IGNOTTI et al, , 2010a(IGNOTTI et al, 2010bMASCARENHAS et al, 2008;SILVA et al, 2010). …”

Due to the current growth of the Brazilian population income and energy consumption and an increase in the population density in urban areas, air quality in the crowded Brazilian cities is being questioned. In searching for a solution we analyzed both the Brazilian and Regional (São Paulo state) public policies of air quality that have been issued since 1981 by confronting them to the air quality official indexes. Following the growth of the national vehicle fleet, 48.8 million in 2012 from 9.3 million in 1980, the total carbon dioxide emissions tripled. At regional level, PM 2.5 measurements have been carried out systematically since 1999 in the Metropolitan Region of São Paulo city, the largest Brazilian city, with 19.7 million inhabitants, and more than 7 million vehicles powered mainly by fossil fuels. Although the numbers are still above the state standard to be reached (10µg.m -3), there was a decrease on the annual average in 2008-2015 compared with 2001-2007. This was partially due to the limits established for new vehicles by federal programs. The analysis indicated that the reduction of air pollutants emission will be more easily achieved based on strategies that combine policies supported by current laws, government and private sector agreements and the community engagement.
