This paper reviews the potential occupational hazards associated with chronic exposure to nitrous oxide. The evidence that chronic exposure to the gas produces problems related to reproduction in dental personnel is convincing. Recent evidence suggests that scavenging systems decrease the adverse effects which nitrous oxide has on fertility of dental surgery assistants. However, even in the presence of scavenging systems trace levels of the gas can exceed recommended minimum levels.
本文综述了长期接触氧化亚氮可能存在的职业危害。有确凿证据表明，牙科工作人员长期接触该气体会产生与生殖相关的问题。最近的证据表明，废气清除系统可减少氧化亚氮对牙科手术助手生育能力的不利影响。然而，即使有废气清除系统，该气体的痕量水平仍可能超过建议的最低水平。
