I found a reference in another group (comp.arch) to health problems
with nanotubes.

Are CNT based on C-60 "footballs"? - there was an article recently
about some serious health safety problems with carbon nanotubes, in
the danish Ingeniøren periodical (Engineering Weekly, http://ing.dk -
alas, it requires login and besides, it's in danish).

Tumors in mice, fish getting braindamages, pretty nasty stuff.

This is all nanotubes in a breathable form.
Much as with asbestos cement, it's not a risk if it's in a big lump.
