Not particle board (as mentioned in the article) but sheets of inexpensive Chinese plywood I picked up had a very strong formaldehyde smell. I had never smelled that in plywood before (or at least so strongly).
I've sworn off particle board in my shop decades ago (for reasons having nothing to do with formaldehyde) but quickly added cheap Chinese plywood to the exclusion list.
I have resigned myself to opening my wallet for the expensive stuff (that costs over $100 for a 4' x 8' sheet, Europly, etc.). Europly at least seems to be formaldehyde free.
