南昌市地铁一号线运营前地下车站空气质量调查

Survey on Air Quality in Underground Stations of No. 1 Metro Line in Nanchang before Operation

摘要

摘要:
目的了解南昌市地铁一号线运营前地下车站空气卫生质量状况，为地铁卫生管理和疾病预防控制工作开展提供依据和建议。
方法 2015年10—12月，对南昌市地铁一号线（共24座地铁车站）随机抽样检测了12座车站的二氧化碳、一氧化碳、甲醛、可吸入颗粒物、噪声、照度、空气细菌总数指标，按照《公共交通等候室卫生标准》（GB 9672-1996）评价空气卫生质量。
结果南昌地铁一号线候车区（站台和站厅）内全部合格项目为二氧化碳和一氧化碳浓度，其余指标甲醛、可吸入颗粒物、噪声、照度、空气细菌总数合格率分别为99.07%，100%，36.57%，100%，91.39%及100%，97.69%，51.85%，99.07%，99.72%。
结论南昌市地铁一号线运营前地下车站空气卫生质量总体状况良好，但噪声是地铁站台和站厅中需要重视的卫生学问题。

Abstract:
Objectives To understand the sanitary quality of air in underground stations of No. 1 metro line in Nanchang before operation, and to provide scientific evidence and suggestion for hygienic administration as well as disease control and prevention.
Methods Air samples were randomly selected from 12 stations of No. 1 metro line in Nanchang during October to December in 2015. Indicators for air quality, such as carbon dioxide, carbon monoxide, formaldehyde, inhalable particulates, noise, illumination and bacteria indexes, were detected. The sanitary quality of the air was evaluated according to the requirements of the National Hygienic Standard for Public Transport Waiting Room (GB 9672-1996).
Results Carbon monoxide and carbon dioxide in the waiting area (platform and station hall) of subway stations showed the qualified rates of formaldehyde, inhalable particulates, noise, illumination and air bacteria index were 99.07%, 100%, 36.57%, 100% and 91.39% in platforms and 100%, 97.69%, 51.85%, 99.07% and 99.72% respectively in station halls.
Conclusions The sanitary quality of the air in underground stations of No. 1 metro line in Nanchang was quite well, but should devote much attention to the platform and hall of stations.
