ADA, CCA, ACQA and other arsenical compounds in treated lumber

I was taking another look at the Western Wood Preservers Institute
website. Contrary to what I had been led to believe inorganic
arsenic compounds do migrate from treated products. I still don't know
if they bothers flowers but it does give one something to think about
if one is thinking about using treated lumber in boat construction.
