【摘要】 目的调查深圳市地铁11号线的站台和站厅的空气卫生状况及其影响因素。方法根据公共场所卫生监测技术规范和公共场所卫生标准的要求,于2016年4月8—20日9:00~15:00,对深圳市地铁11号线的18个车站站台、站厅空气中温度、相对湿度、室内风速、可吸入颗粒物、二氧化碳、一氧化碳、甲醛、照度、噪声和空气细菌总数指标进行测定和评价。结果站台和站厅的空气细菌总数均值正常,站台空气细菌总数超标率为0.14%,站厅空气细菌总数超标率为0.12%,除2个地铁站的站台和站厅的细菌总数存在1次超标(复测均合格)外,包括温度、风速、可吸入颗粒物、二氧化碳、一氧化碳、甲醛、照度和噪音在内的监测项目指标均合格。站台二氧化碳浓度显著高于站厅二氧化碳浓度(P<0.01),站厅的照度显著高于站台照度(P<0.01),站厅噪声显著高于站台噪声(P<0.05)。结论站台和站厅有部分指标存在差异,深圳市地铁11号线站台及站厅的室内空气质量状况良好。更多还原

【Abstract】 [Objective]To investigate the air sanitary conditions and its influencing factors of the platform and station hall of Metro Line 11 in Shenzhen City.[Methods]In accordance with the requirements of technical specification of health monitoring for public places and hygienic standard for public places,the air sanitary conditions of the platform and station hall of 18 stations of Shenzhen Metro Line 11 from 9:00 AM to 15:00 PM during 4-20 April 2016 were detected and assessed. The indicators included temperature,relative humidity,indoor wind speed,total particulate matter,carbon dioxide,carbon monoxide,formaldehyde,illuminance,noise,and airborne bacteria.[Results]The average values of total airborne bacteria in the platform and station hall were normal,and the exceeding standard rate of airborne bacteria of the platform and station hall was 0.14% and 0.12% respectively. The airborne bacteria count of the platform and station hall in two stations exceeded the limit one time(the retests were qualified),while the results of other indicators,including temperature,wind speed,total particulate matter,carbon dioxide,carbon monoxide,formaldehyde,illuminance and noise,all were qualified. The carbon dioxide concentration of the platform was significantly higher than that of the station hall(P<0.01),the illuminance of the station hall was significantly higher than that of the platform(P<0.01),and the noise intensity of the station hall was significantly higher than that of the platform(P<0.05).[Conclusion]The results of some indicators are different between the platform and the station hall. Indoor air quality of the platform and station hall of Shenzhen Metro Line 11 is in good condition.更多还原
