摘 要:通过2018年1月的污染天和非污染天在上海人民广场地铁站对装有屏蔽门系统的1号线站台和装有安全门
系统的2号线站台上的颗粒物数量浓度进行监测并作对比研究ꎬ结果表明:污染天和非污染天ꎬ安装屏蔽门系统的站台颗
粒物数量浓度相对于安全门系统分别降低208% ~3544%和569% ~5131%ꎮ 屏蔽门站台的颗粒物浓度表现为后站台
前站台中站台ꎻ安全门系统颗粒物浓度无规律ꎮ 屏蔽门系统站台的颗粒物在人体内的沉积量要低于安全门系统ꎬ站台两
端的颗粒物在人体内的沉积量高于站台中间ꎮ

Abstract:Thequantity concentrationof particulatematter ontheplatformof subway line 1with screen door
system and line2 with safety door systemwere monitored during polluted and non ̄polluted daysinJanuary2018
at Shanghai Peoples Square subway station. 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.
