Exposure to Fine and Ultrafine Particles in the Stockholm Subway

Exposure to Fine and Ultrafine Particles in the Stockholm Subway

High concentrations of particulate matter have been measured in several subway networks worldwide. This study examined micro-and nanoparticles on 20 metro platforms in the Stockholm Subway. Measurements were taken using sensors mounted on custom-built boards and were later analyzed with code. The results indicate significant differences in both particle concentration and size distribution between stations, especially when comparing indoor and outdoor platforms. It is also probable that some stations exceed the recommended guidelines. The experiment is one of the most extensive measuring campaigns in Stockholm regarding the number of platforms examined. These findings highlight the importance of investigating subway air quality and could aid future research into this relevant topic.
