I posted this lower down as a comment, but some might be interested to know what specific glue is being used:
Most manufactured wood building materials contain one of these two types of formaldehyde-based glues:
* Phenol-formaldehyde (PF)
* Urea-formaldehyde (UF).
Its water resistant properties make phenol-formaldehyde glue more effective for production of exterior wood materials. Urea-formaldehyde glue, cheaper and less tolerant of excessive moisture, is most often used for interior materials including wall paneling, flooring and cabinetry.
In its natural state, softwood lumber emits a tiny amount of formaldehyde. While PF-glued products typically emit 10 times the formaldehyde outgassed by softwood, UF resins can release at least 100 times more formaldehyde than the natural wood.
A typical particle-board subfloor made with UF glue can release enough formaldehyde to result in a 0.3 ppm concentration of formaldehyde in a room. For healthy people who are not bothered by formaldehyde, the levels in softwood lumber and PF glue are usually not considered a serious health problem.
UF glue, on the other hand, has been implicated is causing people to become hypersensitive; a good reason for healthy people and sensitive people to avoid UF glues altogether"

- sizzle 5y agoWhat’s with the distinctly sweet wood smell when you buy Ikea furniture, is it formaldehyde?
- rexreed 5y agoAs a further point to the above, while UF and PF are very prevalent for engineered / manufactured woods and planks of all types, it's possible to make manufactured bamboo planks without the use of formaldehyde-based glues. You need to look for "NAF" (No-Added Formaldehyde) tested and certified bamboo products.
