Pressure Treated Wood
Chromated Copper Arsenate is what was used in pressure treated lumber to
make it resistant to pests & rot from dampness. However, in the USA, this
substance is being phased out and something that is supposed to be less
toxic is being used to replace it. Regardless of which type of pressure
treated lumber you purchase, there will be a small plastic tag stapled on to
it [again, this is in the USA] which identifies the wood as being pressure
treated and lists the precautions to take when handling & machining the
wood. Very specifically, do not inhale or ingest the sawdust or shavings
from this wood. Given that allowing a bird to chew on wood produces a lot
of splinters and chips of wood, allowing a bird to have toys made of
pressure treated lumber is a *BAD* idea. It should be fairly easy for the
bird to ingest dangerous amounds of both chromium and arsenic, both of which
are very toxic to living animals. I'd expect you to have a very sick or
even more likely dead bird on your hands shortly after allowing it to chew
on pressure treated lumber.
