 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.
