In Reply to: garden use of ACQ treated wood posted by Jean Landphair on April 11, 2003 at 14:53:27:
: I am planning to build wooden boxes to enclose raised beds for a vegetable garden. How can I know that ACQ is any safer that the old CCA-treated wood? I've seen the warnings to aquatic life; would that have any bearing on growing food in proximity to the wood?
Hi Jean,
I personally do not believe in using chemicals treatments near food, or for the use in childrens playground equipment. The University of Florida has done studies
New Study from University of Florida (Final Draft)
"Leaching and Toxicity of CCA-treated and alternative-treated wood products"
Dr David Stilwell had done studies on the uptake of plants of arsenic but I am not aware of any on acq that have been done.
Some people in the past have recommended lining beds of treated wood with plastic to prevent plant uptake but that would only address some issues when it came to arsenic.
If you would wish to write a letter to my list asking your question I would be quite happy to send it out and perhaps someone would have an answer for you.
I personally after become poisoned by cca wood am quite aware now of the effects of chemicals and pesticides on the human body and would not choose an option for my garden that in included chemical treatments.
Take care and please keep safe.
Deborah
