Abstract

GIODA, Adriana; TONIETTO, Gisele Birman  and  LEON, Antonio Ponce de. Exposure to the use of firewood for cooking in Brazil and its relation with the health problems of the population. Ciênc. saúde coletiva [online]. 2019, vol.24, n.8, pp.3079-3088.  Epub Aug 05, 2019. ISSN 1413-8123.  https://doi.org/10.1590/1413-81232018248.23492017.

Indoor air pollution is exacerbated by the burning of firewood in rustic stoves and poorly ventilated environments. Exposure to the pollutants emitted by this type of fuel results in increased morbidity and mortality. In Brazil, studies and estimates regarding these conditions are scarce. In order to understand this problem, the objective of this work was to investigate the use of firewood using the data series of government agencies to estimate the number of exposed people. The results indicated that firewood is the second most used fuel for cooking, being used by a significant portion of the population, more than 30 million Brazilians. A decisive factor in the increased use of this fuel is the socioeconomic level of the population associated with the price of liquefied petroleum gas (LPG). The studies carried out in the country recorded high concentrations of particles during firewood burning, exceeding the limits suggested by the World Health Organization (WHO). Associations were also observed between the exposure to the pollutants generated by the burning and the aggravation of health problems, among them respiratory diseases and cancer. Replacing fuelwood and other solid fuels with cleaner fuels should be the government’s goal to minimize health costs.
