于冬、夏季对吸烟、不吸烟铁路旅客列车车厢空气质量分别连续调查了三个往返。结果表明车厢空气质量欠佳,除多数B(a)P外,IP、CO、CO_2大部或全部超标。不吸烟列车空气质量冬、夏均优于吸烟列车和“混合列”的两种车厢。吸烟是车厢空气的重要污染源。开展不吸烟列车势在必行。BaP、IP、CO是评价吸烟污染的有效指标。室内空气污染对人体健康的危害越来越成为环境与健康的重要课题。吸烟排出的烟雾是室内污染的主要因素。旅客列车车厢是一种特殊的室内环境。为掌握我国定型旅客车厢空气污染与吸烟的关系,以便为开展不吸烟列车和制订车厢卫生标准提供科学依据,我们于1985～1986年在吉林一大连的301/2次、吉林一长春的95/6次旅客快车上进行了有关调查。现将结果报告如下。
In winter and summer of smoking, non-smoking railway passenger train air quality were continuously investigated three round-trip. The results showed poor air quality in the cabin, with the exception of most B (a) P, with most or all of IP, CO and CO 2 exceeding the standard. Non-smoking train air quality winter and summer are better than smoking trains and “mixed column” of the two compartments. Smoking is an important source of air pollution compartment. It is imperative to carry out non-smoking trains. BaP, IP, CO are effective indicators to evaluate smoking pollution. The harm of indoor air pollution to human health has increasingly become an important issue for the environment and health. Smoking Smoke emitted is the main factor of indoor pollution. Passenger train compartment is a special indoor environment. In order to grasp the relationship between air pollution and smoking in our country’s stylized passenger compartment so as to provide a scientific basis for carrying out non-smoking trains and formulating hygiene standards for carriage, we conducted a survey in 301/2 times in Dalian No.1 from 1985 to 1986, 6 times on the passenger train conducted a survey. The results reported below.
