为了解西安市地铁二号线环境卫生现状,对西安地铁二号线首通段17个站点的站台、站厅环境空气、空调系统相关指标及生活饮用水常规项目进行检测。依据GB 9672—1995《公共交通等候室卫生标准》、GB/T 18883—2002《室内空气质量标准》、GB 50157—2003《地铁设计规范》、GB 5749—2006《生活饮用水卫生标准》、GB 50325—2010《民用建筑工程室内环境污染控制规范》、GB 18871—2002《电离辐射防护与辐射源安全基本标准》、《公共场所集中空调通风系统卫生规范》(2006)进行评价。环境空气中相关指标结果显示,气压、湿度、照度、CO、CO2、风速、甲醛、噪声、苯、甲苯、二甲苯、NO2、O3、SO2、环境γ射线、总挥发性有机物、氡的合格率均为100%,温度、PM10、菌落总数合
In order to understand the status quo of the environmental health of Metro Line 2 in Xi’an, the stations, station air environment, air conditioning system related indicators and drinking water routine items of 17 stations in the first section of Xi’an Metro Line 2 were tested. According to GB 9672-1995 “public transport waiting room health standards”, GB / T 18883-2002 “indoor air quality standards”, GB 50157-2003 “subway design specifications”, GB 5749-2006 “drinking water health standards”, GB 50325-2010 Code for Control of Indoor Environmental Pollution Caused by Civil Construction Engineering, GB 18871-2002 Basic Standards for Safety of Ionizing Radiation Protection and Radiation Sources, and Code of Hygienic Practice for Central Ventilation and Ventilation Systems in Public Places (2006). The results of relevant indicators in ambient air showed that the passing rate of atmospheric pressure, humidity, illumination, CO, CO2, wind speed, formaldehyde, noise, benzene, toluene, xylene, NO2, O3, SO2, All were 100%, temperature, PM10, the total number of colonies
