通过对上海地铁A线和B线两条隧道内的温度、相对湿度、PM-I、PM2. 5和PM10进行实时监测，了解地铁站内交通微环境的气候和PM特征。此外，通过ICP分析隧道中收集的地板灰尘颗粒的金属元素组成。A线隧道（有站台屏蔽门）中所有PM水平与气象参数之间存在较强的相关性，而B线隧道（无站台屏蔽门）中这些参数之间的相关性较弱。PM2.5和PM10在两条线路的高峰和非高峰时段之间分别呈现显著性差异（p < 0.05）。然而，PM 1显示出不同的模式，A系p > 0.05，
In this study, real-time monitoring campaigns were conducted in two tunnels (Line A and Line B) at a subway station in Shanghai, including temperature, relative humidity, PM-I, PM2.5 and PM10, in order to understand the climate and PM characteristics in the transportation microenvironment. In addition, collected floor dust particles in the tunnel were analyzed by ICP for their metal elemental composition. Strong correlations occurred between all PM levels and meteorological parameters in the tunnel of Line A (with platform screen doors), in comparison with the weak correlations between such parameters in the tunnel of Line B (without platform screen doors). PM2.5 and PM10 between peak hours and off-peak hours for both lines presented significant differences (p < 0.05), respectively. Nevertheless, PM1 showed a different pattern, with p > 0.05 for Line A and p
