加州大学洛杉矶分校的研究发现,火灾发生后燃烧区的家中野火造成的室内空气污染仍然很高,对健康构成持续风险。 UCLA study finds indoor air pollution from wildfires remains high in burn zone homes after fires are out, posing ongoing health risks.

加州大学洛杉矶分校2026年1月2日发布的一项研究发现,在2025年洛杉矶野火熄灭后,在燃烧区的家中,室内有害挥发性有机化合物(包括苯等致癌物)的含量仍然较高。 A UCLA study released January 2, 2026, found that indoor levels of harmful volatile organic compounds, including carcinogens like benzene, remained elevated in homes within burn zones after the 2025 Los Angeles wildfires were extinguished. 研究人员在恢复阶段检测到的室内污染水平高于在主动燃烧期间检测到的室内污染水平,受烟雾破坏的材料继续释放出毒素。 Researchers detected higher indoor pollution levels during the recovery phase than during active burning, with smoke-damaged materials continuing to release toxins. 尽管住在室内,居民仍面临重大接触风险,促使专家建议改进通风、高效过滤器和空气净化器,以减少火灾后恢复期间的健康风险。 Despite staying indoors, residents faced significant exposure, prompting experts to recommend improved ventilation, high-efficiency filters, and air purifiers to reduce health risks during post-fire recovery.
