And what's really cool is that the cause of this particular type of peripheral neuropathy can be determined diagnostically by a nerve biopsy, hence the successful lawsuits.

2,5-Hexanedione (2,5-HD) is the most important metabolite of n-hexane and methyl ethyl ketone (MEK) in humans, and is responsible for the peripheral neuropathies.

That reduction has to do with hexane's unique ability to cause peripheral neuropathy, a permanent destruction of the nerves in the lower legs and arms. You can
google Niki sneaker inventor whose last name was Bowman. He invented the sneaker in his wife's kitchen using rubber cement and her waffle iron. At that time, rubber cement's solvent was always hexane. A common name for hexane is still the "rubber solvent."
Mr. Bowman became a multimillionaire, but he walked with canes for the rest of his life.
There were a number of lawsuits in the late 1980s and early 1990s including some artists who were exposed during printmaking. 3M got sued in one case for a spray
adhesive personal injury.
Also google "metabolism of n-hexane" and you can show them the mechanism that makes normal hexane uniquely good at doing this and why it is replaced with heptane
most often. One extra carbon on the chain makes a big difference in this potential.
There are so many great stories about n-hexane. The article you want I think is in the old AIHA journal before the merged with ACGIH. I will take a look, but
that is more like archaeology than a file search in my office after this long.

Subject: [DCHAS-L] Workplace Hexane exposures
I recall seeing a fairly concise article that provided an overview of the impacts of hexane exposures to auto mechanics in California in the mid-1990's, when the products they used were reformulated to reduce their VOC contents. I'd like to share this article
with industrial hygiene students here, but haven't been able to find it quickly. Does anyone know where I can find it?
Thanks for any help with this.
