Circulatory disease mortality rates in the elderly and exposure to PM2.5 generated by biomass burning in the Brazilian Amazon in 2005

Mortalidade por doenças circulatórias na população idosa e exposição a PM2,5 em decorrência das queimadas na Amazônia brasileira em 2005

Mortalidad por enfermedades cardiovasculares en los ancianos y la exposición a PM2,5 como resultado de la quema en la Amazonia brasileña en 2005

The aim of this study was to analyze the association between the exposure to fine particulate matter and circulatory disease mortality rates in the elderly living in the Brazilian Amazon. An ecological study of circulatory disease, acute myocardial infarction and cerebrovascular disease mortality rates in micro areas of the Brazilian Amazon was carried out. The environmental exposure indicator used was percentage hours of PM2.5 concentrations > 25µg/m³ divided by the total number of estimated hours of PM2.5 in 2005. The association between exposure and circulatory disease mortality rates was strongest in the oldest age group. No significant statistical association was found between cerebrovascular disease mortality rates and exposure. Circulatory disease mortality rates in the elderly living in the Amazon have been influenced by atmospheric pollution from emissions caused by forest fires.
