野火烟雾的PM2.5每年造成约24,100名美国人死亡,这与气候变化和缺乏联邦法规有关。 Wildfire smoke's PM2.5 causes about 24,100 U.S. deaths yearly, linked to climate change and lack of federal regulation.

《科学进步》发表的一项新研究将长期接触野火烟细微粒物质(PM2.5)与2006年至2020年美国下48个州每年平均24,100人死亡联系起来。 A new study published in Science Advances links chronic exposure to wildfire smoke's fine particulate matter (PM2.5) to an average of 24,100 deaths annually in the lower 48 U.S. states from 2006 to 2020. 研究人员发现,在野火造成的PM2.5每立方米每增加0.1微克时,每年约增加5 594人死亡,其中神经疾病对健康的影响最大。 Researchers found that for every 0.1 microgram per cubic meter increase in PM2.5 from wildfires, about 5,594 additional deaths occurred each year, with the strongest health impacts tied to neurological conditions. 这项研究强调气候变化、更频繁的野火以及火灾易发地区的发展导致公共卫生风险日益增大。 The study highlights growing public health risks due to climate change, more frequent wildfires, and development in fire-prone areas. 虽然采用了县一级的数据和对其它原因的控制,但限制包括烟雾分布不均和缺乏吸烟数据。 While county-level data and controls for other causes were used, limitations include uneven smoke distribution and lack of data on smoking. 专家们强调,需要加强联邦对目前不属于环保局监督范围的与野火有关的PM2.5的监管。 Experts stress the need for stronger federal regulation of wildfire-related PM2.5, which currently falls outside EPA oversight.
