RESULTS
The average concentration of FA in dissection room was 0.68, 0.85, and 0.73 ppm in the 4th, 10th and 14th weeks, respectively. A significant variation in indoor FA concentrations was observed in different areas of the dissection room and also during the dissection sessions. FA concentration was higher during body cavity or deep dissection (Table 1). In all sessions, FA levels near the dissecting table were higher than in the areas away from it. The average personal exposure level for the students was 0.75, 1.20, and 1.10 ppm and 1.27, 1.44 and 1.33 ppm for instructors during the 4th, 10th and 14th week, respectively (Table 1)
