Community & Environmental Health Theses & Dissertations
Nitrous oxide is a gas often used in dental, surgical and veterinary operations as an anesthetic agent. Employees stationed in proximity of fugitive gas emissions may potentially suffer adverse health effects from chronic exposure to this agent. Passive dosimeters can be worn in the breathing zone of potentially affected personnel during exposure periods, then later analyzed to quantify nitrous oxide exposure. This study sought to establish the accuracy of several commercially available passive monitoring devices for nitrous oxide by comparison against an infra-red spectrophotometric reference method.

Halsey (1991) summarized the underlying reasons for continuing concern about the problem of waste anesthetic gases. Careful and systematic monitoring studies indicate that individual trends in anesthetic pollution levels are not as low as was confidently predicted 10 years ago, when scavenging devices became commonplace. Second, there are now clear legal requirements for assessment of the situation. It is estimated that each year more than 200,000 health professionals are occupationally at risk of illness as a consequence of chronic exposure to low doses of waste anesthetic gases (Rogers, 1986).
