Abstract The concentration of anaesthetic gases was determined in the breathing zone of personnel in 102 operating theatres and 16 recovery rooms of 28 hospitals in northern Germany. The tentative limit for nitrous oxide of 50mL/m3 was exceeded by 26% of the values measured in the breathing zone of 250 anaesthetists. The maximum permissible concentration for halothane (5mL/m3) was exceeded by 8% of the measured concentrations. The tentative limits for enflurane and isoflurane of 10mL/m3 were not exceeded in any case. Far lower concentrations were measured in the breathing zones of 260 nurses than for anaesthetists. The results as well as published data of similar studies and the quality of presently available equipment were used to propose recommendations for maximum permissible levels (90mg/m3 for nitrous oxide, 40mg/m3 for halothane and 16mg/m3 for enflurane and isoflurane).
