摘要
目的了解邹城市中央空调通风系统卫生状况,为制定控制措施提供依据。方法将正在运行使用的中央空调关闭,无菌采集中央空调通风系统送(回)风口的积尘样品并检测积尘中细菌总数、真菌总数。在中央空调运行状态下,采集中央空调送风口空气样品,检测空气中的细菌总数、真菌总数、可吸入颗粒物和二氧化碳。结果在所测207份样品中,通风管道(口)积尘量合格率仅为24.6%,细菌总数合格率为36.2%,真菌总数合格率为24.6%;送风口空气质量存在安全隐患,所测项目均有不同程度的污染。结论邹城市公共场所中央空调通风系统污染严重,对人群健康构成潜在威胁。
OBJECTIVE To understand sanitary condition of centralized air ventilation system in Zoucheng City. To provide a basis for strengthening health supervision and giving control measures. METHODS Dust sample in blast pipe was collected when centralized air ventilation system was off, the total content of the bacterium and fungus was examined.Air sample was collected in air-supplied outlet when centralized air ventilation system is operated.The total content of the bacterium, fungus,inhaled particle,carbon dioxide in the air were tested. RESULTS In 207 samples, the qualified rate of the content of dust was only 24.4%, the qualified rate of the total content of bacterium and fungus were 35.6% and 23.5% respectively. There was potential safety hazard in the air-inlet port, defferent level contamination existed in all the projects we monitored. CONCLUSION The centralized air ventilation system is seriously polluted, and it will do a potential threat to human health.
