太原市地铁试运营期间室内空气卫生状况调查

Investigation on indoor air sanitary conditions during trial operation of the newly-bulit metro line in Taiyuan, China

摘要

摘要:
目的监测和评价太原市地铁试运营期间室内空气卫生状况，为地铁正式投入运营后卫生管理提供依据和建议。
方法 2020年11—12月，根据《公共场所卫生检验方法》(GB/T 18204)、《室内氡及其衰变产物测量规范》(GBZ/T 182-2006)等标准，对太原市地铁试运营期间室内空气中细菌总数、甲醛、氨、苯、甲苯、二甲苯、臭氧、一氧化碳、二氧化碳、可吸入颗粒物、氡及其子体等卫生学指标进行检测。
结果 23个车站的站厅、站台层检测项目中空气中细菌总数、甲醛、氨、苯、甲苯、二甲苯、臭氧、一氧化碳、二氧化碳、可吸入颗粒物、氡及其子体合格率均为100%，但温度不能满足公共场所卫生限值要求。换乘站与非换乘站、站厅层和站台层间的细菌总数、氡及其子体浓度检测结果均无显著性差异；装修对氡及其子体浓度的影响无显著性差异。
结论太原市地铁试运营期间23个车站室内空气卫生状况良好，建议相关部门在正式投入运营前继续加强相关卫生管理和监测，保障乘坐地铁人群的健康。

Abstract:
Objective To monitor and evaluate the sanitary conditions of indoor air before operation of the newly-built metro line in Taiyuan, and provide basis and suggestions for the sanitary management after the metro line formal operation.
Methods From November to December in 2020, total number of bacteria, formaldehyde, ammonia, benzene, toluene, xylene, ozone, carbon monoxide, carbon dioxide, inhalable particles, radon and its decay products were measured during the trail operation of the newly-built metro line in Taiyuan according to the Examination Method for Public Places(GB/T 18204), the Specifications for Monitoring of Indoor Radon and Its Decay Products (GBZ/T 182-2006).
Results A qualified rate of 100% was observed for total number of bacteria, formaldehyde, ammonia, benzene, toluene, xylene, ozone, carbon monoxide, carbon dioxide, inhalable particles, radon and its decay products in the air of the stations halls and platforms in 23 stations, but the temperature could not meet the health limit requirements of public places. There were no significant differences in the total number of bacteria and the concentrations of radon and its decay products between the transfer stations and the non-transfer stations, and between the hall and the platform; there were no significant differences in the concentrations of radon and its decay products between the stations with different degrees of decoration.
Conclusion During the trial operation of Taiyuan Metro, the indoor air sanitation of 23 stations was good. Relevant departments should continue to strengthen health management and monitoring before the official operation of the metro to ensure the health of the public travelling in the metro line.
