Abstract
The burning of biomass has a significant impact on the Amazon ecosystem in the dry season due to the emissions of air pollutants. The effects on the health of the population, especially in the region of the arc of deforestation, has been the subject of recent studies. The scope of this study was to evaluate the spatial distribution of biomass burning and mortality from respiratory and cardiovascular diseases among the elderly in the state of Rondônia in the period from 2001 to 2012. Mortality data were obtained through the Mortality Information System of the Ministry of Health. Biomass burning data were provided by the National Institute for Space Research. The Kernel estimator was used. The highest mortality rates were observed in the central-east and south-east of Rondônia. The focuses of the fires were concentrated in the northern part of the state, though with a significant amount in other regions. The spatial distribution of the hot areas of mortality and fires were not directly associated. However, fires were observed in all municipalities in the state. Pollutants emitted from biomass burning can be transported thousands of kilometers from the source areas and influence the health of the elderly.
