A more reasuring study to read

You'll see that this study looks mainly at human exposure and less at lab animals. Also, note that the "activator" used in the previous study cited was sulfuric acid (basically, battery acid), not citric, acetic acid, lime or lemon juice. This, too could be a significant factor to consider.

No need to freak out, folks. We do need to be vigilant and open to new, clarifying information, though...whether we may want to hear it or not.

Best to all--
