2023 年纽约市 7 月 4 日烟花导致空气污染暂时增加了 200 倍，水样显示东河中烟花金属的含量是其两倍。 2023 NYC Fourth of July fireworks caused a temporary 200x increase in air pollution, with water samples revealing double the levels of firework metals in the East River.
纽约大学Langone Health的一项研究表明,纽约市7月4日2023年的烟火展示导致空气污染大幅上升,污染物含量高达每天微粒浓度平均值的200倍。 A study by NYU Langone Health revealed that New York City's 2023 Fourth of July fireworks display led to a significant surge in air pollution, with pollutant levels up to 200 times the average daily fine-particle concentration. 在一些地区,空气质量要达到12小时才能恢复到正常水平,从东河采集的水样比铅、镍和等烟火颜色所用的金属量高出一倍。 Air quality took up to 12 hours to return to normal levels in some areas, and water samples collected from the East River had double the levels of metals used to create firework colors, such as lead, nickel, and antimony. 研究人员认为,大型烟花展示会暂时加剧空气污染,可能对人和环境的健康造成危险。 The researchers suggest that major firework displays can create a temporary spike in air pollution that may pose a health risk to both humans and the environment.
