Methanol turns into formaldehyde in the first step of its metabolism in the human body. Therefore it should be considered a source of formaldehyde. Perhaps the most dangerous source of formaldehyde due to its ability to penetrate the blood brain and other barriers that prevents preformed formaldehyde to reach vital organs. I have enclosed a recent article of mine that might help you understand the added risk of this common and often airborne source of formaldehyde. The article I have attached has all of its references available on my website whilesciencesleeps.com If the reference number from the article is entered into the home page of the website the original reference will come up for consideration. I hope this helps. There is no need for this communication to remain anonymous. Woodrow C. Monte Professor Emeritus of Food Science and Nutrition Arizona State University woodymonte@gmail.com
