Gordon:
Exactly, glad to see you join in the discussion. I
will be interested in your reaction to a note I just sent to DCHAS list. Th
is response is not going to the list.
Some folks just love carcinogen classification lists. It
makes life simple for them, they do not have to exercise any professional j
udgement, if is a carcingen ban it. Note that recent entry from the individ
ual with the theatrical workers union. I would loved to have responded to t
hat one noting the theatrical workers complex exposures and life style issu
es.
As an aside, if formaldehyde WERE a nasal carcinoge
n Washington and Oregon as leading producers of plywood , made using formal
dehyde adhesives, should have extraordinary numbers of nasal cancers in the
ir cancer registries. I do not think that is the case. In any analysis one
would also have to consider wood dust as a potential carcinogen. Damm, life
does get complicated when you have to consider all the facts!!
Best regards,
Roger
