Pollution by waste anaesthetic gases was measured in all operating departments in a typical N.H.S. district. Methods were chosen to provide time-weighted average levels over the period of each operating session. The results showed that air-conditioning alone could not guarantee pollution levels below suggested maximum levels and that to meet those requirements air-conditioning plus scavenging was necessary. Background pollution levels were found to be representative of the personal exposure of nursing staff but approximated to only one third of the anaesthetists' personal exposure. Dental clinics presented special problems, namely the very high levels of pollution to which the dentist and his assistants were exposed.
在一个典型的国民保健服务（N.H.S.）地区的所有手术室中，对废弃麻醉气体的污染情况进行了测量。选择的方法是提供每个手术时段内的时间加权平均水平。结果表明，仅靠空调无法保证污染水平低于建议的最高水平，要满足这些要求，空调加废气清除是必要的。发现背景污染水平代表了护理人员的个人暴露情况，但仅约为麻醉师个人暴露水平的三分之一。牙科诊所存在特殊问题，即牙医及其助手所接触的污染水平非常高。
