列车车厢内环境质量现状调查

目的了解旅客列车车厢内环境质量现状。方法参照相关卫生标准,采取统一的监测方法对不同车次始发列车车厢内环境空气质量进行现状调查。结果所有抽检列车车厢内平均温度高于国家标准,硬座车噪声和空气细菌总数、软座车PM10、餐车噪声平均值超出国家标准。硬座车车厢内照度低于软卧车、餐车;硬座车噪声低于餐车,但高于软卧车;硬卧车噪声低于餐车,空气细菌总数高于餐车;差异均有统计学意义,P〈0.01。结论不同列车车厢应根据污染现状进行相应的改善。

Environmental quality trains Ye Shaoyan

Objective To understand the environmental quality inside the passenger train the status quo.Methods The reference to the relevant standard, unified monitoring measures taken on different trips originating trains Survey ambient air quality.Results All sampling train compartments,the average temperature is higher than the national standard,seat car noise and air total bacterial count,soft seat car PM10,dining car noise than the average national standard. Car seat than soft illumination inside car,dining car;seat dining car noise below,but higher than soft sleeper cars;hard noise below the dining car,the total number of bacteria in the air above the dining car;the differences were significant,P0.01.Conclusion Pollution in train compartments should be improved accordingly.
