As with all things we do in the shop, care must be taken, and all
things we read must be investigated before believing. However, that
being said, please note that the research link you have is from one of
the largest manufacturers of CA glue (and its derivatives) in the US
today.

To me, that is kind of like quoting the the tobacco companies' research
that assures us there is no link to smoking and health issues. After
all, they even said it to a Congressional investigative commitee that
was looking specifically into health problem allegations.

This is one of many I found from an independent. There was a lot out
there, and I realize this is something like 5 years old... but if
carefully read it does voice its own concerns. Nothing long term, but
I would caution that it is an older warning, too.

And remember, the big difference we are talking about is grinding this
stuff up and inhaling it into our blood stream (sanding). They are
testing this stuff for simple fumes... nothing else.

Grinding this to dust is much different than using as intended, as an
adhesive that will polymerize and while giving off small amounts of
fumes, it is basically inert. That is why the glue itself is commonly
used in dentistry, etc. BUT IN THAT CASE IT WAS USED AS IT WAS
INTENDED, not as the questioner asked.

It has not been tested for actual inhalation of the solid particulates,
as it simply was not designed for the usage phrased in the question.

And one more time, why take ANY chance, for ANY reason for a hobby?
