Re: Re:Additional concerns: regarding formaldehyde

[Guest guest]

Dr. Thrasher, Thank you so much for responding to my concerns. I will be

talking with you privately on the issues at hand a little later. My having a

farm acre of mold in this building in the HVAC system, etc. and illnesses from

the mold, just made me wonder if there are any added vapor's from the

formaldehyde adding to the equation. Darlene

Darlene: you have raised some excellent questions. I will answer them one at a

time. Generally, cabinets are made from medium density fiber board for the

shelving. Many years ago thye used particle board. Depending upon the source

of the fabricated wood products they were glued to gether with either or both

ureaformaldehyde or phenolformaldehyde resins. The ureaformaldehyde resin is

very unstable and easily hydrolyzes at room temperature and elevated humidity

releasing formaldehyde. Phenolformaldehyde is very stable and releases very

small amount of formaldehyde. One can test for formaldehyde. Kits are available

for formaldehyde testing via the internet. There is available a relatively

inexpensive passive monitor. The are hung from the ceiling, door jam, etc.

allowed to gather the gas and then are sent to a laboratory for analysis. The

amount of formaldehyde decreases with time.

The major part of releasing occurs in the first two years of product life. The

coating on the surface of the board does cause a reduction in the amount of

formaldehyde that is released. Distinguishing between the two illnesses is the

difficult part. Also, you must know that microbial growth (mold and bacteria)

also produce formaldehyde and other aldehydes that are part of MVOC. A detailed

health and exposure history would have to be taken in attempt to distinguish

between the two. Also, it would probably be necessary to test for the presence

of mycotoxins, urine and mold in sinuses. Me for one I would probably have to

accept that presence of the two and clearly state that both exposures are

contributing to the illness. IIlness from formaldehyde took years to be acceped

and is no longer disputed. Look where mold exposure is today. Jack D.

If someone has a severe allergy to formaldehyde (since childhood), what effect

would that hvae if they were exposed to mold? Would they be more susceptible to

the health efects of mold?

Jackie, my opinion is that, I think he meant test for mycotoxins in the urine,

on that part, correct me if I am wrong Dr. Thrasher. Darlene
