In the previous literature the mean personal FA exposure levels were 1.69 ppm and 1.53 ppm for instructors and students, respectively, while mean area value was 0.50 ppm [9], 1.24 ppm as the mean personal exposure level and 1.65 ppm indoor FA level, for the length of time required for completion of assignments in the gross anatomy laboratory [12]. However, they neither mentioned the difference between personal exposure levels and indoor concentrations, nor between instructors and students. It has also been reported [8,9,12] that the FA levels are variable depending on the region being dissected. Therefore it is important to know the personal exposure levels in each laboratory session.
