I find that after I visit big stores that have lots of dusty particle

(as the formaldehyde-laden dust is most likely being ventilated
throughout
the store).

Would hardly think that the source of the dust is the particle board, but
is dust that has settled onto the particle board from other sources.
Would
be very surprised if the dust itself has *any* urea-formaldehyde content
at
all. Now, in those stores, if it is new particle board, there is
certainly
the possibility that the material is still out-gassing. But that is
entireley different than assigning the blame to dust.



I sanded some particle board by hand and got a very bad reaction. I
assume it's the "dust". If I spend some time in Home Depot or Mennards I
end up with some shortness of breath. Ace Hardware, Sears, Kmart, Harbor
Freight---no problems. Knowing this, would you still not blame the dust?
