Homebrew PCBs

I basically agree with that

BUT i have surely some hundred kilograms of iron in various forms in/around 
my house.
These will kill me, but only if i swallow them or maybe a piece falls on my 
head.


I mean you won't apply ferric cloride to your body, at least not on 
purpose.
so any mg/kg rating is not of much use i think. (Kevin, i hope you don't 
talk us in
volunteering for LD50 tests of Fe3Cl on Humans ;-) )

More of interest is if the ferric cloride is a danger to wastewater 
cleaning facilities.
It's just not ok to make them trouble if you can avoid it.


I most like the idea of neutralizing and let evaporate the water.
then put the salt residue in the trash bin. But i wouldn't disagree
that neutralizing and pooring in the drain would be a possibility, i really
don't think the solved copper is that bad.
