Wildfires release fine particulate matter, or PM2.5, into the air, and these tiny particles can travel deep into the lungs and bloodstream and cause asthma attack, heart attack, or stroke.
women and individuals with existing respiratory or heart problems, are more vulnerable to PM2.5 from wildfires, Choi said.
They found that California, Florida, Texas, Georgia, Alabama and North Carolina are likely to have the highest number of premature deaths due to the volume of particulate matter distributed by the smoke. Cities located near fires, such as Los Angeles, Houston and Atlanta, will also likely see a spike in early death and corresponding economic losses, the study determined.
The authors point out that these may be underestimates as changing patterns of temperature could drive the number of wildfire-related premature deaths even higher. “In this era of climate change, if we remove flammable vegetation and do things like create green fire breaks and reduce the fuel for the fires, we can substantially decrease the harm of smoke downwind in populated areas," Gao said in a Cornell news release.The study was published in the June issue of the journalDr. Neil Schachter is a professor of pulmonary and community medicine and medical director of pulmonary rehabilitation at Mount Sinai Medical Center in New York City.
