For the determination of the amount of formaldehyde released from the inside wall of cupboards and chests of drawers made of plywood, 3 test methods were studied. They were colorimetric determination of formaldehyde absorbed to paper (paper-absorption method) or water (surface-absorption method, bubbling method) used for absorbants. The surface-absorption method, putting a Petri dish containing water in the drawer, was the most practical. In this method, the amount of formaldehyde absorbed in water per cm2 of dish area for 24 hr was able to indicate the amount of formaldehyde released from the inside of furniture. By this method the amounts of formaldehyde released from 23 pieces of furnitures were determined.
