I find that after I visit big stores that have lots of dusty
particle board, plywood and MDF stacked around that I have a
shortness of breath for a while

the
wood (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?

Most of the dust you see in a Home Depot comes from the concrete
floor, not the lumber. So perhaps it's concrete that you're having
trouble with? Sears, K-Mart, and Ace Hardware all put some kind of
flooring on top of the concrete--never been in a Harbor Freight so
don't know what they do.

Rather than guessing, you really should if this is of serious concern
to you see an allergist.
