The results showed that the quantity concentration of particulate on the platform with screen door system reduced by2.08% ~35.44% and5.69% ~51.31% than that with safety door systeminpollutedandnon ̄polluteddaysꎬrespectively. Theconcentrationofparticulateontheplatformwith screen door from hightolow inorderwas:attherearꎬinthefrontandinthemiddleoftheplatform. Thepartic ̄ ulate concentration with safety door system was irregular. The amount of particulate matter deposited in human body on the platformwith screendoor systemwaslowerthanthatwith safety door system. Theamountof particu ̄ late matter deposited in human body at the ends of the platform were higher than that in the middle.
