西安市地铁2号线运营前地铁站室内空气卫生质量

Indoor Air Quality of Metro Line 2 Stations before Commercial Operation in Xi'an

摘要

摘要:
目的了解西安市地铁2 号线运营前17 座车站室内空气卫生质量状况。

方法根据《公共场所卫生监测技术规范》(GB/T 17220-1998),对17 个车站站台、站厅的温度、相对湿度、风速、一氧化碳(CO)、二氧化碳(CO₂)、甲醛、可吸入颗粒物(PM₁₀)、空气细菌总数、噪声、照度进行监测。

结果 16 号地铁站温度均值以及9、10 号地铁站PM₁₀ 均值超标,其余14 个地铁站各项卫生指标均合格。17 个车站站厅温度、CO₂、甲醛值均高于站台;相对湿度、噪声、照度水平均低于站台,差异有统计学意义(P<0.05)。

结论西安市地铁2 号线运营前室内空气卫生质量状况良好,建议地铁开通后加强卫生监测工作。

Abstract:
Objective To analyze the indoor air quality of 17 stations of metro line 2 in Xi'an.

Methods With reference to the Technical Rules of Health Monitoring for Public Places (GB/T 17220-1998), indicators including temperature, relative humidity, wind velocity, carbon monoxide (CO), carbon dioxide (CO₂), formaldehyde, respirable particular matter (PM₁₀), air bacteria, noise, and illumination were detected in the 17 station halls and platforms.

Results Except the temperature of Station 16 and the PM₁₀ in Stations 9 & 10 were higher than the standards, the indicators of the other 14 stations were all within the acceptable limits. The temperature, the concentrations of CO₂ and formaldehyde were higher in the station halls, and the relative humidity, noise levels, and illumination levels were higher in the platforms (P<0.05).

Conclusion The indoor hygienic quality of Xi'an metro line 2 is at a high level. Routine hygienic monitoring should be performed after the commercial operation.
