stop telling people to cut up their motherboards!! pcb is released into the air!
I think he's confusing printed circuit boards (PCBs) with PolyChlorinated Biphenyls - used in HV transformer 'oil'.
One has...somewhat harmful particles, the other causes ...almost every medical problem known to be painful and suck.

What is "hasr mful"??
This isn't a question - it should be a forum topic.
. PCBs are not that hazardous (a dust mask should provide adequate protection - any volatiles will be long gone, so vapor shouldn't be a problem) and haven't been used in electrical equipment in years.. I'd be more worried about fiberglass and resin (or whatever they use in circuit boards) dust.
