摘　　要：目的了解深圳地铁5条线路地下车站运营前的空气卫生质量。方法对67座地下车站分别检测其站厅、站台空气中CO、CO2、PM10、甲醛和空气细菌总数，以及集中空调通风系统新风量、风管内表面积尘量和微生物指标，按照GB9672--1996《公共交通等候室卫生标准》和WS394--2012《公共场所集中空调通风系统卫生规范》评价空气卫生质量。结果地铁1～5号线67座地下车站空气CO、CO2、PM10、甲醛、室内空气细菌总数检测均值和CO各次检测值均达到GB9672--1996标准；CO2、PM10、甲醛和室内空气细菌总数各次检测值超标率分别为3．23％（23／712），11．47％（89／776），5．46％（39／714）和2．54％（17／670）。67座地铁地下车站集中空调系统新风量、风管内表面积尘量、细菌总数、真菌总数和β－溶血性链球菌检测值合格率均为100％。结论深圳地铁车站运营前空气卫生质量较好。Objective To know the indoor air quality during the final acceptance of 67 subway stations in Shenzhen Metro Line 1 to 5. Methods The relevant indicators such as carbon monoxide and fresh air exchange quantity and so on were detected in 67 stations. Their air qualities were assessed according to the requirement of the National Hygienic Standard for Public Transport Waiting Room and the Hygienic Specifications of Central Air-conditioning and Ventilation System in Public Places. Results The average levels of detected indicators, such as carbon monoxide, carbon dioxide, inhalable particulate matter, formaldehyde, indoor air bacteria, fresh air exchange quantity, dust in air ducts, total bacterial counts, total number of fungi and β-hemolytic Streptococcus in the inner surface of ducts, all passed the hygienic standard for public transport waiting room and the hygienic regulation of central air-conditioning and ventilation system in public places. Conclusion The air quality of Shenzhen metro stations during the final acceptance accords with the two national hygienic standards.
