Dr. Eimy Bonilla, lead author of the research study, says: “While Indigenous territories account for fairly few fires in the Amazon Basin, our research shows that individuals residing in these areas experience considerably higher health risks from smoke particles, compared to the general population.”
Previous research in the field focuses on the health impacts of nations on larger scales or is greatly reliant on healthcare facility admission information. This does not properly highlight the impact on individuals residing in native areas as they are typically situated much closer to the fires, are exposed to smoke particles for longer durations of time, and do not have access to proper healthcare, hygiene products, and clean water. The new study, led by researchers at Harvard University, utilizes a mix of climatic chemical transport designs and an upgraded concentration response function to approximate the rate of early mortality for Indigenous populations exposed to high concentrations of PM2.5.
Wildfires release small smoke particles called PM2.5, which are understood to considerably contribute to aerosol concentrations and negatively impact human health. Smoke particles from biomass burning in the Amazon Basin travel excellent ranges, impacting air quality throughout a number of nations in South America.
” These fires are having a disproportionate effect on people residing in Indigenous areas. With longer exposure times, and minimal access to medical attention, Indigenous populations are at much greater threat of death from fires,” says Bonilla. “We advise that governments provide financial assistance to keep track of air quality in these areas, providing affordable sensing units to study the impact of brief- and long-term exposure to the smoke.”

Native individuals in the Amazon Basin are two times as likely to die too soon from wildfire smoke direct exposure than the wider South American population. Approximately 12,000 premature deaths occur every year due to smoke from wildfires, with about 230 in Indigenous areas.
A new research study, published in IOP Publishings journal Environmental Research: Health, reveals that Indigenous people in the Amazon Basin are twice as most likely to pass away too soon from smoke exposure due to wildfires than the broader South American population. Regions in Peru, Bolivia, and Brazil are identified as particular hotspots for smoke exposure, with mortality rates increasing to as high as 6 times that of the general population.
The outcomes show that smoke from wildfires in South America accounts for around 12,000 premature deaths every year from 2014 to 2019, with roughly 230 of these deaths happening in Indigenous territories. Direct exposure to damaging smoke particles is discovered to be much higher throughout the Amazonian dry season, from July to November each year, when wildfires more than double the increase in PM2.5 concentrations.
A recent study in the journal Environmental Research: Health has actually discovered that Indigenous individuals in the Amazon Basin are twice as most likely to die prematurely from smoke exposure due to wildfires compared to the wider South American population. Wildfires launch small smoke particles called PM2.5, which are known to significantly contribute to aerosol concentrations and negatively effect human health. Smoke particles from biomass burning in the Amazon Basin travel terrific ranges, impacting air quality across several countries in South America.
“We suggest that federal governments offer financial support to keep an eye on air quality in these areas, supplying low-priced sensors to study the impact of brief- and long-lasting direct exposure to the smoke.”
