What about that fake wood made from recycled plastics? ~ jan

You don't understand the nature of toxins (and you're wrong, PT lumber is
not _usually_ labelled as hazardous).

Arsenic isn't "poisonous, period". It is a hazard to people, but not
provably a problem to your fish. It could potentially harm other creatures
in your pond (snails - but it's the copper, not the arsenic), but there's
no good evidence of that. It isn't something you should chew on (I stopped
one of the dogs doing that yesterday), but is generally considered safe
when used with care.

CCA treated lumber has been banned for residential use in the US.

Not quite. EPA.gov says "As of January 1, 2004, EPA will not allow CCA
products to be used to treat wood intended for most residential settings"

not cut this wood indoors and use a mask so you don't ingest the sawdust,
but after the structure is in place, I have read no warnings about it

And sawdust is something you shouldn't be inhaling anyway :-)

In the old days, CCA was used, but now for residential applications the
material is ACQ or Alkaline Copper Quaternary, which has several times the
amount of the copper found in the old CCA. The Quaternary compounds are
organic ammonia compounds, which are not addressed in the MSDS, the same way
as the copper. Near the end of the MSDS it is listed as a marine pollutant.
Doc Johnson had information about the use of CCA treated wood, in which he
recommended that if you we3re going to use it, at least allow it to weather
some first. Freshly treated wood, which is soaked under pressure in the
appropriate chemical, has an excess of the treatment solution on the
surface, which is water soluble. By allowing some weathering, excess salts
are washed from the surface, making the rest of the treatment unlikely to
pollute the pond.

Look, all I'm saying is toxins are toxins. I stand in front of the

treated wood in the local lumber yard and the big sign there warns me of
such. I think I have succeeded when Elain at least thinks about what
she
might do. Personally, if any of you want to use whatever to build your
pond, I could care less. I made a point and it was as simple as that.
Elaine, I apologize for stirring up a bunch of garbage regarding your
post.

No apologies necessary. As you pointed out, you made me think and I
thank you for that. I hadn't considered what is actually in pressure
treated wood and whether it could leach into my pond. That's why I'm
