Minimal is famous about the potential of river-tunnels to boost PM2.5 levels in subways. We hypothesized a "river-tunnel" effect is present Stations right beside badly ventilated tunnels that travel beneath rivers exhibit higher PM2.5 concentrations than much more distant stations. Accordingly, the PM2.5 levels were checked at stations right beside and two- and three-stations remote from the river-tunnel. Multivariate linear regression analysis was carried out to disentang
