In this study exposure to anesthetic gases in health care workers of a hospital of Milan was investigated. The evaluation focused on the period 2007-2010 and was performed by environmental monitoring (20 operating rooms and 54 samples) and biological monitoring (180 workers and 242 urine samples). Mean airborne exposure was 3:15 and 0.34 ppm for nitrogen protoxide (N2O) and sevorane; in end-of-exposure urine samples the concentration of N2O and hexafluoroisopropanol, metabolite of sevorane, were 4.85 mg/L and 0.21 mg/L, with 80 and 21% of values below the quantification limit. Sevorane monitoring exceeded or equaled the environmental limit value of 0.5 ppm and the biological exposure index in 17 and 11% of measures. There were no observed exceedances of the limit for N2O. The anesthetist and scrub nurse were tasks with greater exposure. There was a significant correlation between airborne halogenated gases and urinary hexafluoroisopropanol. The results of this study indicates that further efforts are needed to improve the hygienic conditions in the investigated hospital.
