a considerable impact\u201d from wildfire smoke exposure over time, says environmental health scientist Stephanie Cleland of Simon Fraser University in Burnaby, Canada, and the Vancouver Coastal Health Research Institute. Health impact assessments like this underscore the benefit of investments to build smoke resiliency, says Cleland, who wasn\u2019t involved in the study.<\/p>\n\n\n\n<p>Fine particulate matter, called PM<sub>2.5<\/sub>, describes airborne particles of pollution that have a diameter of 2.5 micrometers or smaller. Once inhaled, these microscopic particles can travel all the way to the lungs\u2019 alveoli, the delicate air sacs surrounded by tiny blood vessels, where oxygen is exchanged for carbon dioxide. There\u2019s evidence that the particles can even enter the bloodstream.<\/p>\n\n\n\n<p>Studies have found that exposure to fine particulate matter pollution is linked to lung damage, an increased risk of a heart attack and <a href=\"https:\/\/www.sciencenews.org\/article\/air-pollution-shaving-year-our-average-life-expectancy\">reduced life expectancy<\/a> (<em>SN: 8\/22\/2018<\/em>). Along with wildfires, sources of PM<sub>2.5 <\/sub>include <a href=\"https:\/\/www.sciencenews.org\/article\/us-neighborhoods-40-years-worst-air-quality-pollution\">fossil fuel combustion, factories<\/a> and agriculture operations (<em>SN: 7\/30\/20<\/em>).<\/p>\n\n\n\n<p>Historically, the research field has treated exposure to wildfire smoke as \u201cthis very acute event \u2014 it comes in, people are exposed to really high concentrations and then it leaves,\u201d Cleland says. Studies have reported health harms in the short term, including <a href=\"https:\/\/www.sciencenews.org\/article\/wildfire-smoke-health-risks-air-quality-pollution\">upticks in hospital visits for chronic lung conditions<\/a> (<em>SN: 9\/18\/20<\/em>). But there\u2019s been a recent shift to understanding the health risks \u201cwhen someone\u2019s exposed to years\u2019 worth of smoke,\u201d Cleland says.<\/p>\n\n\n\n<p>Michael Jerrett, an environmental health scientist at UCLA\u2019s Fielding School of Public Health, and his colleagues created a mathematical model to tackle the issue. The team used annual averages of wildfire smoke exposures over an 11-year period to try to capture the long-term effect on mortality. With early evidence suggesting that PM<sub>2.5<\/sub> from wildfires may be more toxic than fine particulate matter from other sources, the team built that assumption into the model. The researchers also estimated the exposure to PM<sub>2.5<\/sub> specifically from wildfires, rather than from a composite of sources.<\/p>\n\n\n\n<p>To get a better understanding of the long-term effect of wildfire smoke exposure, the next step is to follow a group of people over a decades or two to compare the death rates between those who\u2019ve been exposed to higher concentrations of wildfire smoke and those who\u2019ve experienced less, Jerrett says. But considering the amount of time such a study takes, his research team started with the mathematical model approach. <\/p>\n\n\n\n<p>With how often wildfires are occurring and how they are projected to get worse with climate change, \u201cit was really important to get some overall estimate of the size of this problem.\u201d<\/p>\n\n\n\n\t\t\t<\/div>\r\n<br>\r\n<br><a href=\"https:\/\/www.sciencenews.org\/article\/wildfire-smoke-pollution-premature-death\">Source link <\/a>","protected":false},"excerpt":{"rendered":"<p>Wildfire season got off to an early start in Northern California with the Corral Fire, which started burning grasslands in San Joaquin County on June 1 and grew to cover more than 50 square kilometers.
