Notes:
Wallpaper is not included in this table.
(1) Pine can give off formaldehyde during a period after fixing. This is most likely because of the drying method that has been used.
(2) Certain colour pigments make it necessary to give the material a lower evaluation as a waste product.
(3) Chipboard is often covered with a plastic laminate based on phenol or melamine. This reduces the product's environmental profile even more.
