加利福尼亚州的Salton Sea尘埃伤害小鼠肺部健康, 即使没有活微生物, 也引起附近居民的担忧。 California’s Salton Sea dust harms lung health in mice, even without live microbes, raising concerns for nearby residents.

California不断缩小的Salton Sea的灰尘改变了肺微生物体, 并引发小鼠的免疫反应, Dust from California’s shrinking Salton Sea alters the lung microbiome and triggers immune responses in mice, according to a UC Riverside study published in mSphere. 即使没有活微生物,尘埃也会在Pseudomonas和Staphylococccus等有害细菌中造成剧增,并将免疫细胞增加60%,这表明仅污染物就可能破坏肺部健康。 Even without live microbes, the dust caused spikes in harmful bacteria like Pseudomonas and Staphylococcus and increased immune cells by 60%, suggesting pollutants alone can disrupt lung health. 研究结果引起了附近社区的关切,特别是呼吸道疾病社区的关切,并突出说明了环境退化和气候变化如何可能助长慢性肺病。 The findings raise concerns for nearby communities, especially those with respiratory conditions, and highlight how environmental degradation and climate change may contribute to chronic lung issues.
