If you want to get information about environmental toxicity and its relationship to human health there is only one place to start (aside from my blog) and that is the Environmental Working Groups site – www.ewg.org.
A recent National Geographic article from their October 2006 issue, used quite a bit of information that EWG had produced without giving them the propoer credit. In my opinion, while its great that NG brought this important issue to the forefront, they still needed to credit this fine organization for doing work that others are too scared to publish.
