I thought it was some other chemical that caused ALS. Nobody knows what causes ALS.
Chemophobia is an irrational fear of things with chemical names.
Did you know that Formaldehyde is found in the human body as a metabolic product and that the studies that resulted in a claim that formaldehyde is a carcinogen were rat studies with high exposures and they were pretty weak indeed.
AS for formaldehyde and ALS, this was a survey study with exposures calculated on response items.
People were surveyed–and the researchers “calculated” formaldehyde exposures based on the surveys so, in fact no exposures were actually determined.
That’s just the beginning of why these studies are not reliable and should not make the journals or the news. In fact they shouldn’t even pass the smell or laugh test.
A better study would be of people with high exposures, like morticians, so why didn’t they do that?
