Although much research is being conducted on the characteristics of PM2.5 and PM10 at subway stations, there is no research focusing on a complex subway transfer station. In this paper, the characteristics of PM2.5 and PM10 at transfer stations are studied. For comparison, monitoring is performed under different outside conditions at four different transfer stations in the non-peak period during March 2018. The concentrations of PM2.5 and PM10 on the platform in the transfer stations is approximately 10 mu g/m(3) lower than in the non-transfer station, when outside PM2.5 is lower than 150 mu g/m(3) However, the ratio of PM2.5 to PM10 at the transfer stations (lowest 78.1%) is higher than at the non-transfer station (lowest 61.2%), indicating that the PM10 content differs from the non-transfer station. In a transfer station with the same depth, the PM concentration is the same or similar. In addition, the concentration of PM2.5 at subway stations has a strong correlation with the outside environment (R-2=0897), which indicates that an outside condition is important for the subway environment.
