暑运期间旅客列车空气质量调查分析

目的了解暑运期间全路不同类型旅客列车空气质量状况。方法参照相关卫生标准和规定,采取统一的动态监测方案。结果各监测指标均存在不同程度的超标情况,空调旅客列车以CO2超标最严重,且车厢内CO2的监测值与超员人数呈现较明显的正相关关系(r=0.389,F=125.59,P<0.01)。结论暑运高峰期空调列车的空气质量值得关注,应进行相应的改善。

The Investigation and Analysis of the Ambient Air Quality in the Passenger Train during the Summer Vacation Transportation

Objective To study the hygienic status of the ambient air quality in the passenger train during the summer vacation transportation. Methods Adopt uniform dynamic monitoring in accordance with the national standard and specifications. Results Indexes are mostly higher than the current standard, the carbon dioxide is badly overload in air-conditioned trains, and the carbon dioxide monitor value present obvious correlation with the overstrength population in trains(r=0.389,P<0.01). Conclusion The quality of the passenger train should be taken intervene measures during summer vacation transportation.
