This story tells us that "pressure treated lumber" will no longer be produced because it contains chromated copper arsenate, or CCA.
See: http://www.usatoday.com/news/nation/2003-12-29-treated-lumber_x.htm Interestingly enough, lumber that is pressure treated with nanometer sized silver particles will also prevent the lumber from rotting. Silver has the added benefit that the wood does not become brittle like CCA pressure treated lumber. frank key -- The silver-list is a moderated forum for discussion of colloidal silver.
