In the last year I've heard more and more about concerns of plastic off gassing. The most troubling being a report on NPR I heard a couple of nights ago. Apparently, a guy wrote a book about all sorts of toxic stuff that is causing all sorts of health problems. When asked to list the "most wanted", I think the second item in his list was the plastic commontly used for sports water bottles. That seems like a pretty common sort of plastic for beverages. It makes me wonder about the plastic that bottled water comes in. And the plastic in the plumbing. Anybody know much about this sort of thing?
