北京市西城区公共场所卫生状况调查

Sanitary Status in Public Places of Xicheng District in Beijing

摘要

摘要:
目的了解北京市西城区公共场所卫生状况, 为加强公共场所监督, 保障公共场所卫生安全提供依据。
方法按照《公共场所卫生监测技术规范》(GB/T 17220-1998) 和《集中空调通风系统卫生管理规范》(DB 11/485-2011) 的方法进行采样监测。参照《公共场所卫生标准检验方法》(GB/T 18204.1~18204.30-2000) 和《公共场所空气中可吸入颗粒物(PM₁₀)测定方法光散射法》(WS/T 206-2001) 进行检测。依据《公共场所卫生标准》(GB 9663~9673-1996) 和《集中空调通风系统卫生管理规范》(DB 11/485-2011) 对结果进行评价。
结果公共场所用品用具的合格率最高(98.6%), 不合格项目为细菌总数。公共场所空气质量与集中空调通风系统合格率相近, 分别为94.3%和94.2%。主要不合格项目为甲醛和冷却水中嗜肺军团菌。
结论公共场所用品用具的消毒效果较好。公共场所甲醛的合格率较低, 可以采用增加新风量和放置绿植的方式降低室内甲醛浓度。对集中空调冷却塔的处理要做到清洗消毒彻底, 无死角。
