A new study has provided a comprehensive, city-wide map of air pollution exposure within Shanghai’s subway system, identifying platform design and train schedules as critical levers for improving commuter health.
The research found that particulate matter concentrations on underground platforms consistently exceed outdoor levels, with exposure peaking in unexpected patterns. Conducted through year-round monitoring of PM2.5 and PM10 at key stations, the study found indoor pollution levels were highest during winter weekday mornings...
Platform screen door (PSD) design emerged as the most significant influencer, with stations featuring full-height barriers showing markedly lower PM levels than those with older, half-height designs.
