Bradley" <ax876@chebucto.ns.ca> Someone inquiring about independent sources of information which condemns the use of "pressure-treated" wood, is welcome to download and/or view my small collection on my public directory: http://www.chebucto.ns.ca/~ax876/ptwdatat.txt If you need more than the six or seven pages of these independent sources, just post me a msg. ---------- Forwarded message ---------- Date: Tue, 11 Jan 2000 11:46:42 -0400 From: Helen Jones <hjones@chebucto.ns.ca> Both Copper Chromate Arsenate (CCA) and Pentachlorophenols are commercially used in treated wood, and both have related bodies of scientific literature indicating significant health concerns from various forms of contact with them. One thing I haven't seen dealt with is the fate of leachate near house foundations. Capillarity draws considerable moisture in through concrete basement walls and floors (as anyone who has attempted to store cardboard there knows). It seems to me that waterborn leachate from outside treated wood (decks, etc) has the potential to concentrate on the inner walls of residential concrete foundations through evaporation of any leachate pulled in through these surfaces. One possible alternative to consider is the product "Lifetime Wood Treatment" which has been used in Banff National Park and in Sweden predating that, I believe. Information is available on this through various local sources and through a company in Stevensville Ontario, Natural Insect Control: http://www.natural-insect-control.com (page 32 in their catalogue) nic@niagara.com (905) 382-2904, FAX (905) 382-4418 Helen Jones -*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*- The preceding message was posted on the Sustainable Maritimes mailing list (sust-mar). http://www.chebucto.ns.ca/lists/sust-mar -*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*- Sponsors: Chebucto Community Net http://www.chebucto.ns.ca Sierra Club - Chebucto Group http://www.sierraclub.ca Volunteer listowner: Paul Falvo sust-mar-owner@chebucto.ns.ca
