摘　　要：目的调查分析广州地铁三号线的室内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》的要求,对广州地铁三号线18个地铁站的站厅、站台和3列列车车厢的室内空气进行卫生监测。结果部分地铁站和车厢的温度、噪声、照度、空气细菌总数不合格:(1)候车区少数检测点温度高于标准,车厢大部分检测点温度低于标准;(2)噪声超标情况较严重,超标率车厢(100%)﹥站台(66.67%)﹥站厅(36.67%);(3)少数站厅检测点照度低于标准;(4)空气细菌总数超标率站厅(14.44%)﹥站台(7.78%)﹥车厢(6.67%)。结论广州地铁三号线室内空气质量存在一些卫生问题,有待改进。客流量是导致理化指标超标和空气细菌污染物浓度升高的重要因素,加强地铁站空调系统卫生管理对于确保室内空气质量有积极意义。OBJECTIVE To investigate and analyze indoor air sanitation status and its affecting factors of Guangzhou metro line 3. METHODS According to Technical Rules of Hygienic Monitoring in Public Places, hygienic monitoring was conducted in lobbies, platforms of 18 subway stations and compartments of 3 subway trains. RESULTS Some of the monitoring values of temperature, noise, illuminance and total of bacteria, were not qualified according to the requirements of national standards.1. Minor monitoring values of temperature in waiting areas were higher than that in national standards, while major in compartment were lower than that in national standards.2.Unqualified rates of noise from high to low were 100% of compartment, 66.67% of platform and 36.67% of lobby. 3.Minor monitoring values of illuminance in lobbies were not qualified.4. Unqualified rates of total of bacteria from high to low were 14.44% of lobby, 7.78% of platform and 6.67% of compartment. CONCLUSION There are some problems with indoor air quality of Guangzhou metro line 3. Population flow has an important effect on monitoring values of physical and chemical items and air bacterium pollutant. Strengthening sanitation government of air-conditioning system in metro is helpful for guaranteeing the indoor air quality.
