铁道部部颁《旅客列车卫生监督管理规程》规定,客车内部空气中细菌总数冬季不得超过6000个/m~3、夏季不宜超过4500个/m~3,CO浓度不得超过0.15％,CO浓度不得超过10mg/m~3。为了解辖内旅客列车空气质量是否符合部颁要求,并为改善提供依据,我们于1989年列377次快车和477次慢车进行了空气质量调查,结果如下。一、377次快车((表1)
Ministry of Railways ministerial “Passenger Train Health Supervision and Management Regulations” provides that the total number of bacteria in the air inside the bus shall not exceed 6000 / m ~ 3 in winter, summer should not exceed 4500 / m ~ 3, CO concentration shall not exceed 0.15%, CO concentration may not More than 10mg / m ~ 3. To understand whether the air quality of passenger trains within its jurisdiction complies with the requirements of the Ministry and to provide the basis for improvement, we conducted an air quality survey of 377 express trains and 477 slow trains in 1989.
