科罗拉多·博尔德大学进行的一项研究发现,在科罗拉多2021年马歇尔大火附近摧毁了1 000多所房屋的房屋面临野火烟和灰烬遗留的健康风险。 A study by the University of Colorado Boulder found that homes near the 2021 Marshall Fire in Colorado, which destroyed over 1,000 homes, faced lingering health risks from wildfire smoke and ash. 室内空气质量受到严重损害,危险气体持续数周,与1990年代洛杉矶城市的污染水平类似。 Indoor air quality was severely compromised, with hazardous gases lingering for weeks, similar to pollution levels in urban Los Angeles in the 1990s. 55%以上的受影响居民报告了头痛和眼睛痒等症状,即使在火灾发生两年后也是如此。 Over 55% of affected residents reported symptoms like headaches and itchy eyes, even two years after the fire. 开放窗户和使用空气清洁器等简单措施可以将室内污染物减少50%以上,帮助居民在野火发生后安全返回家园。 Simple measures like opening windows and using air cleaners can reduce indoor pollutants by over 50%, helping residents return safely to their homes after a wildfire.
