The Science article on which toxicity and inhalation of silver vapors,
nanoparticles, and dust is based is bogus.

It is junk science.  A hit piece.

One simply cannot scour the silver literature for only negative information
and write good/fair science.

The authors totally screwed up the silver nanoparticle/oxygen relationship
and failed to pursue research where CS shines,
like with cancer, heart, and body purification.
