摘要
目的了解清远市区公共场所集中空调冷却塔水军团菌污染状况。方法根据《公共场所集中空调通风系统卫生规范》,随机抽取清远市区公共场所24家共135份水样进行军团菌检测。结果17家公共场所59份样品中检出嗜肺军团菌,嗜肺军团菌污染率高达70.8%(17/24),检出率为43.7%(59/135)。结论军团菌存在于公共场所中央空调系统,已对暴露人群的健康造成潜在威胁,应采取有效防范措施。
[ Objective] To study the legionella contamination situation in cooling tower water of central air-conditioning in public places in the city of Qingyuan. [ Methods] According to ＂Hygienical Standards of Centralized air-conditioning ventilation System in Public Places＂, 135 samples from 24 public places were randomly selected for the test of legionella. [ Results] Legionetla pneumophi- la were isolated from 59 samples of 17 public places, the contamination rate was 70.8% （ 17/24） , and the detection rate was 43.7% （59/135}.
