Benzene in your soda?

Yum. Interesting column at cbs4.com on the chemical brew which can result from the combination of Vitamin C, or ascorbic acid, and benzoate preservatives. Apparently heat and sunlight can mix these to make benzene, which I'm pretty sure is a known carcinogen. I'm not a chemist, but it might be worth checking out the Environmental Working Group website for this and more stuff that you'd probably rather not know about but should.
