持续的反向层捕获了污染物, 导致犹他州和爱达荷州的空气质量危险, 盐湖城是美国最糟糕的. A persistent inversion layer trapped pollutants, causing hazardous air quality in Utah and Idaho, with Salt Lake City worst in the U.S.

高压系统导致整个伊达霍和犹他州的空气严重停滞,盐湖城的空气质量好几天来一直处于美国最差的状态,原因是存在持续的倒流层捕捉污染物。 A high-pressure system has caused severe air stagnation across Idaho and Utah, with Salt Lake City experiencing the worst air quality in the U.S. for several days due to a persistent inversion layer trapping pollutants. 虽然爱达荷州的博伊西和双瀑布也面临危险空气，尤其是对弱势群体而言，但犹他州的状况更为严峻，当地媒体将这段时期称为“雾霾之日”。 While Boise and Twin Falls in Idaho also face hazardous air, especially for vulnerable populations, Utah’s conditions are more severe, prompting local media to label the period the "Days of Haze." 即使健康的个人也面临长期的接触风险,官员们建议限制户外活动,因为整个星期的空气质量预测一直很差。 Prolonged exposure risks even healthy individuals, and officials advise limiting outdoor activity amid ongoing poor air quality forecast through the week.
