车厢及候车室氨的检测与分析

Detection and Analysis on Public Spaces Ammonia Contamination at Train Cars and Waiting Rooms

摘要:
目的了解目前车厢及候车室氨的污染现状, 为进一步完善其卫生相关标准提供科学数据。
方法采用Z800氨气测定仪, 测定车厢及候车室现场环境氨的质量浓度。
结果检测数据表明, 车厢及候车室环境中存在一定浓度的氨。
结论《公共交通等候室卫生标准》(GB9672-1996)、《公共交通工具卫生标准》(GB9673-1996) 以及《旅客列车卫生及监测技术规定》(TB/T1932-2009) 等车厢及候车室卫生相关标准修订时, 应对其环境中的氨指标作出限值规定。
