Our present state of research and knowledge strongly suggests that the volatile agents, halothane, enflurane and isoflurane, present only a minimal threat to our environment. Nitrous oxide, however, has ozone-depleting potential as well as a greenhouse gas effect which may contribute much to the problem of global warming over the next few decades. Release of anesthetic gases into the atmosphere presents a small problem in contrast to other sources of ozone-depleting chemicals and greenhouse gases, but anesthesia providers have a responsibility to minimize unnecessary atmospheric pollution by reevaluating the use of N2O, using low flows of gases and exploring the use of activated charcoal absorption in the scavenging systems to remove volatile agents. Infectious waste, radiation, lasers, chemicals and waste gases pose possible occupational health hazards in the operating room. Each of us should play a critical role in monitoring harmful substances and should actively practice techniques which would lessen the hazards. We should be cognizant of the fact that sources not yet introduced into our environment may have adverse effects on our health and that vigilance and education are key factors in maintaining a safe work environment.
我们目前的研究和知识状况有力地表明，挥发性麻醉剂氟烷、恩氟烷和异氟烷对我们的环境仅构成极小的威胁。然而，氧化亚氮具有消耗臭氧层的潜力以及温室气体效应，这可能在未来几十年对全球变暖问题产生很大影响。与其他消耗臭氧层化学品和温室气体的来源相比，麻醉气体释放到大气中是一个小问题，但麻醉提供者有责任通过重新评估氧化亚氮的使用、采用低流量气体以及探索在清除系统中使用活性炭吸附来去除挥发性麻醉剂，以尽量减少不必要的大气污染。感染性废物、辐射、激光、化学物质和废气在手术室中可能构成职业健康危害。我们每个人都应在监测有害物质方面发挥关键作用，并应积极实践能够减少危害的技术。我们应该认识到，尚未引入我们环境中的物质来源可能会对我们的健康产生不利影响，而警惕性和教育是维持安全工作环境的关键因素。
