研究发现,通过电气化Caltrain减少骑手接触致癌排放的89%。 Electrifying Caltrain reduced riders' exposure to cancer-causing emissions by 89%, study finds.

最近的一项研究表明,在旧金山湾地区,将Caltrain从柴油改成电车,使骑车人接触致癌黑碳的风险减少了89%。 A recent study shows that switching Caltrain from diesel to electric trains in the San Francisco Bay Area reduced riders' exposure to cancer-causing black carbon by 89%. 这一变化还降低了该站周围的黑碳水平,凸显了铁路系统电气化带来的重大环境效益。 This change also decreased black carbon levels around the station, highlighting the significant environmental benefits of electrifying rail systems. 该研究表明,使更多的美国铁路系统电气化可能对空气质量和公共卫生产生重大的积极影响。 The study suggests that electrifying more U.S. rail systems could have substantial positive impacts on air quality and public health.
