摘 要:为调研武汉市地铁的乘车环境,对地铁2号线出口处、地下站台及车厢进行空气污染物浓度的监测与分析。结果表明:地铁站台及车厢环境内温湿度状况良好,CO浓度较低。但苯、TVOC浓度总体偏高,颗粒物PM2.5、PM10浓度超标较为严重。其中,高人群密度车厢内的空气质量最差,PM2.5、CO2、TVOC的浓度平均值分别达到0.198 mg/m3、1326 ppm、2.050 ppm,均超过国家相关标准。此外,地铁站台出入口处的PM2.5平均浓度最高,达到0.49 mg/m3,超过国家标准5.5倍,出入口处的颗粒物浓度过高会加重站内颗粒物污染。通过结果分析,车厢内合理加大通风量和出入口处安置风幕有利于改善地铁环境。For the investigation of Wuhan city subway travel environment, air pollutants concentration of the export of Metro Line 2, platform underground and carriage, were monitored and analyzed. The results show that: the environment temperature and humidity conditions in subway station and train is well, and CO concentration is lower, but the concentration of benzene and TVOC are high, and PM2.5 and PM10 concentrations exceed the standard more serious. Among them, the air quality of high population density carriage is the worst, and its concentration of PM2.5, CO2, TVOC average value reach 0.198 mg/m3, 1326 ppm and 2.050 ppm respectively, which are more than the relevant national standards. In addition, the subway platform at the entrance and the exit of the average concentration of PM2.5 was highest, reached 0.49 mg/m3, 5.5 times more than the national standard, and the entrance of the particle concentration is too high will increase the station particulate pollution. After the analysis of the results, increased ventilation inside carriage and arranged air curtain at inlet and outlet of carriage are effectively to improve the subway environment.
