A research was carried out on risk evaluation of workers with different tasks in operating theatre. The airborne concentrations were determined by an IR analyzer with two distinct sampling lines: the first was placed in surgical zone and the second one in anesthesiological zone. The anesthetists resulted more at risk than surgical team. Nevertheless when the evaluation was based on N2O urinary concentration and data were stratified according to task a prevalent inhalation absorption resulted for non medical staff (instrumentist and professional nurse). Our data concerning N2O ranged between 95-764 ppm indoor and between 3-92 mcg/l in the urines of exposed subjects.
