Another in vitro study of PM10 from the Stockholm subway also found that the air was 40–80 times more genotoxic and 20–40 more potent at causing oxidative stress when compared with an urban street environment15. Similarly, an underground railway pollution study found that PM2.5 and PM1.8 have greater ability to produce reactive oxygen species (ROS) than coarser PM10; these particles can penetrate the mucous layer, causing an antioxidant response16
