Re: Sensitivity to chemicals and natural selection

[Guest guest]

Body fat mass could also be a factor. As the detox pathway is set up to remove a certain amount. As the 'overload' is placed in/on adipose tissues with lipophilc chemicals. So taking into account adipose tissue in breasts, hips and around internal body organs (for cushioning/protection) that is also a factor. Whether it is brown or white fat.

Not to mention the P450 enzyme that seems to be lacking/low in some people.

One hypothesis as to a species survival benefit associated with increased sensitivity of the females

would be due to their roles as child bearers for the next generation.

Re: Panel on Formaldehyde Emissions from Composite Wood Produ...

Steve:

If you want to study exposure to UF OSB/MDF, look no further than the manufacturing plants and/or the lumbar yards. These guys are exposed to OSB daily, they are exposed to the UF raw materials in relatively high concentrations daily, yet, all the guys that I know (including myself and my workers) are asymptomatic.

One would believe that we would be on the front line of exposure, yet I do not recall ever having the scratchy throat you described due to UF OSB/MDF exposure.

I suppose we are just very lucky.
