AW: [Histonet] Re: Formaldehyde - Carcinogen?

[Gudrun Lang]

Recently I read an article (in German) of an German office, that deals with
dangerous stuff at work.
This article says, that the save level of Formaldehyd should be at 0,1 ppm.
They referred to studies with rats and monkeys, that showed increasing
nose-mucosa-cancer at higher levels. Also the irritant property of
formaldehyd, that causes an steady need of regeneration, has influence on
its dangerousness. This irritation begins at levels above 0,1 ppm.
The outcome of the article was (for me), that if you avoid the irritating
exposure (with fumehoods), you are on the save side.

 "To date there has been no information published to suggest that
pathologists' causes of death are different from those of other American
physicians."

Over here (UK) pathologists have the second highest suicide rate.
This suggests that they haven't had time to get the long term effects of
formalin:-)

Terry - equally pickled.

Beth A. Fye at HCA Richmond [Virginia?] Hospital Laboratories asks:

>>In 2006, the IARC [International Agency for Research on Cancer]
changed formaldehyde from a Group 2a - Probable Carcinogen to a Group I
Carcinogenic to Humans.  Has this changed... any  procedures within
[your] Histology Laboratory?<<

See
http://www.iarc.fr/ENG/Press_Releases/archives/pr153a.html
I never heard of them, but I don't think the IARC is a regulatory agency
- rather they're a subsidiary of the WHO (World Health
Organization) based in France.

Pathologists (at least this pathologist) have a very high lifetime
exposure to formaldehyde. The AMA (American Medical Association) tracks
the causes of death of American physicians very carefully. To date there
has been no information published to suggest that pathologists' causes
of death are different from those of other American physicians.

I'm sure that the herrn inschpektors will soon be belaboring us with
this IARC report, but I don't think there's any new evidence - or if
there is, I wish the IARC or somebody would publish it.
