In the present study, personal FA exposure levels at programs utilizing a dissectionbased
format varied over the duration of the courses, which is contrary to the studies conducted
in 2006 at Japanese medical schools by Ohmichi and colleagues38 and by Shiraishi,55 where ambient air levels of FA increased over time.
The variability in personal FA exposurelevels seen in the present study is most likely due to the method in which FA exposure levels were collected, as indicated by the personal FA exposure levels in the present study versus ambient air FA levels in Ohmichi and colleagues38 and Shiraishi,55 respectively
