A ameaça emergente dos impactos da fumaça dos incêndios florestais sobre a saúde e as mudanças climáticas

The report highlights the severe health risks posed by biomass burning in the Brazilian Amazon, noting that air quality often exceeds WHO safety limits during the burning season. It emphasizes the disproportionate impact on vulnerable groups, including a 25% increase in respiratory hospitalizations among indigenous people over 50. The document argues that these health crises are exacerbated by the COVID-19 pandemic and limited healthcare access in remote regions, calling for a moratorium on deforestation-related fires and improved air quality monitoring.

• Air quality monitoring in Brazil shows that particulate matter levels frequently exceed World Health Organization (WHO) standards during the burning season. Brazil's daily average limit for MP10 is 60 µg/m3, which is higher than the WHO average of 50 µg/m3, and the country lacks limits for MP2.5.
• Wildfire smoke in the Amazon is linked to significant adverse health outcomes, including low birth weight, increased respiratory diseases in children and the elderly, and higher hospital admission rates. In Rio Branco, a study of 2,922 patients showed the most frequent symptoms were coughing (79%), fever (51%), and dyspnea (39%).
• Indigenous populations face extreme vulnerability to smoke pollution. A national study by the Instituto Socioambiental (ISA) found a 25% average increase in hospitalizations for respiratory problems among indigenous people over 50. In Mato Grosso, this increase reached 33.6% during the burning season.
• Air pollution from fires increases the vulnerability of indigenous peoples to COVID-19, a critical concern given that the COVID mortality rate among indigenous populations is 250% higher than the national average.
• Healthcare access in the Brazilian Amazon is severely unequal, with some residents needing to travel over 400 km to reach complex care centers, compared to a national average of 155 km.
• The report identifies the 'Arco do Desmatamento' (Deforestation Arch), extending from Pará in the north to Mato Grosso in the south, and the Brazil-Peru-Bolivia area in the southwest, as the primary regions for wildfire foci.
