郑州市地铁一号线公共场所卫生学评价

Evaluation on Hygienic Status in Public Places of Subway Stations in Zhengzhou

目的评价郑州市地铁一号线运营前的公共场所卫生现状,为卫生行政审批提供科学依据,为今后轨道交通项目的规划建设和设施设计提供科学数据。方法根据国家有关法规、卫生标准,采用国家计量认证检测仪器,随机抽取郑州市地铁一号线5个站点的公共场所进行卫生学评价,检测指标为微小气候、空气污染物、中央空调系统卫生学检测及生活饮用水检测等。结果郑州地铁一号线站厅、站台和车厢温度指标部分监测点不合格;可吸入颗粒物超标比较严重,合格率仅为6.67%;积尘中细菌总数合格率为90%;送风中真菌总数合格率为80%;其他指标均合格。结论郑州地铁一号线公共场所卫生条件除可吸入颗粒物外其它指标基本符合运营条件,建议在运营前对公共场所进行一次系统的清洗和消毒。

Objectives To evaluate the hygienic status of Zhengzhou subway stations before operation to provide scientific basis for hygienic administration and approval,and to provide scientific data for planning construction and designing facilities of rail transit projects in the future. Methods The hygienic status in the public place of 5 subway stations was evaluated according to relevant state laws,regulations,and health standards by certificated instruments. Detection indexes were small climate,air pollutants,the sanitation of central air conditioning system and drinking water,etc. Results The temperature was unqualified in parts of monitoring points in the hall,platform and carriage of Zhengzhou subway stations; the pollution of PM10exceeded the standard limits was serious with a pass rate of only 6. 67%; the pass rate of total bacteria counts in dusts was 90%; the pass rate of total fungal counts in blasting air was 80%; and other indicators were qualified. Conclusions The hygienic status of Zhengzhou subway stations has met the requirement of operation except PM10; a systemic cleaning and disinfecting the environment in public places before operation was suggested.
