We measure the formaldehyde concentration in the dissecting room which parted in a small room in a college. The measurement in the large dissecting room is carried out in the past, but it is not carried out in the dissecting room which parted in a small room. Results are as follows. 1) The formaldehyde concentration is high in the dissection training initial stage, and it gradually decreases for the final stage. A tendency of this concentration change is similar to the other university. 2) In this measurment, acetaldehyde is generated as well as formaldehyde, too.
