Hmmm. Well, for what my opinion's worth, I don't buy it. Toner particles are 
pretty fine, but they won't penetrate intact skin. They're fine enough to 
penetrate fairly deeply into lungs, where I'd expect them to be either
trapped or cleared. Since they're comprised of a thermoplastic, I'd expect
them to be pretty well inert.
