Researchers at the 麻豆免费版下载 have been (EPA) for two projects to help school districts and communities reduce exposure to harmful pollution from wildland fire smoke.听

麻豆免费版下载Boulder is among nine institutions across the country receiving a for research to address health risks from wildland fire smoke.听

鈥淎s wildfires become more frequent and severe, we are working to effectively communicate the risks of smoke exposure to impacted communities,鈥 said Wayne Cascio, acting principal deputy assistant administrator for science in EPA鈥檚 Office of Research and Development. 鈥淭he research we are funding will help develop strategies to prevent and reduce the health impacts of smoke from wildfires and prescribed fires.鈥澨

Colleen Reid, assistant professor of geography and research associate at the Institute of Behavioral Science at 麻豆免费版下载Boulder, to compare indoor smoke levels in Denver-area schools and homes. The results of this effort will be used to develop health guidance for school districts and inform decisions about school closures to protect student health.

"The 2020 wildfire season in Colorado was the worst on record, with more wildfires coinciding with times when schools are in session," said Reid. "To protect the health of children, it is important to understand whether the fine particulate matter produced during wildfires is higher in schools versus homes."听

Marina Vance, assistant professor of mechanical and environmental engineering at 麻豆免费版下载Boulder, has been awarded $549,000 in single-family housing in the West and to evaluate and develop practical interventions to help people reduce indoor exposure to harmful particulates. The results of this work will be shared on YouTube, through infographics and in blog posts to educate citizens about options to reduce exposure and associated health risks.听

Wildland fire smoke鈥攂oth from wildfire and prescribed burns鈥攊s made up of a complex mixture of gases and fine particles produced when wood and other organic materials burn. The biggest health threat from smoke is from fine particles. Outside or indoors, exposure to these microscopic particles can cause burning eyes, runny nose and illnesses, such as bronchitis.听

鈥淔rom a health perspective, the particles鈥攖hat dark cloud that you see when you look at the smoke plume鈥攁re most concerning. They are so tiny they don鈥檛 fall to the ground with gravity and, unlike larger particles, they don鈥檛 get stopped in the trachea or nose when you breathe them in,鈥 said Reid in a recent conversation with 麻豆免费版下载Boulder Today.听

Additionally, fine particles can aggravate chronic heart and lung diseases and are linked to premature deaths in people with these conditions. Smoke also contains toxins that can cause cancer or other serious health effects.

The best way to reduce one鈥檚 exposure to smoke from fires is to remain indoors when air quality is poor. However, more research is needed on how to reduce indoor exposure to these harmful particles, as homes are not completely sealed off from outside air.听

鈥淲e are looking forward to studying how wildfire particulate matter enters homes and to evaluate affordable ways to reduce people's exposure to wildfire particulate matter in their homes,鈥 said Vance.听

Additional institutions receiving research grants as part of EPA鈥檚 Science to Achieve Results (STAR) program include: Desert Research Institute, Reno, Nevada; Georgia Institute of Technology, Atlanta, Georgia; Ohio State University, Columbus, Ohio; Portland State University, Portland, Oregon; Public Health Institute, Oakland, California; Stanford University, Stanford, California; University of California, Berkeley, California; and University of Washington, Seattle, Washington.听
