Pressure treated
wood is commonly used in picnic tables, decks, playground sets -- basically
any outdoor use of lumber. What few outside of the lumber industry
realize, is that 'pressure treated' means the wood is injected with
vast amounts of toxic compounds to preserve the wood and kill termites.
The most commonly
used wood preservative in the United States used to be chromated copper
arsenate (CCA), an insecticide that is 22 percent pure arsenic, a known
human carcinogen. As of Jan. 1, 2004. The Environmental Protection Agency
(EPA) banned chromated copper arsenate (CCA) as a preservative for wood
intended for residential use (except for the lumber that is used in
permanent wood foundations). CCA-treated lumber will still be available
for industrial and agricultural use, however, so be sure to read the
labels carefully if you are buying wood for your own project.
The most common
replacement for CCA is ACQ (alkaline copper quat), a less toxic organic
pesticide. Though the lumber industry maintains that lumber treated
with ACQ is safer for children, no one really knows what the long term
consequences may be. The manufacturer of our outdoor furniture sees
no reason to take a chance, and never uses treated wood. We couldn't
agree more!
White cedar is not
only beautiful, but naturally resistant to insects and the elements,
a much safer choice for your family. You can add a finish if you
like to maintain the warm color of the wood, or you can leave it alone
and it will weather to a beautiful silver.
