Yes Sam, the difference between ethylmercury and methylmecury is much like the difference between ethanol, or ethyl alcohol, and methanol, or methyl alcohol, in fact exactly the same difference, though I suppose the difference in metabolism between ethylmercury and methylmercury is not the same as the difference in metabolism between ethanol and methanol. As far as I’m aware, ethyl- and methylmercury don’t metabolize further, but methylmercury builds up while ethylmercury probably just gets excreted. The alcohols both get metabolized to their aldehydes, which means ethanol becomes acetaldehyde which goes on to be oxidized further to acetic acid (or acetate if you’re a biologist) and methanol becomes formaldehyde, which then turn into formic acid (or formate if you’re a biologist) which turns eventually into carbon dioxide. Anyway, acetaldehyde and formaldehyde are both toxic, but formaldehyde is much more so. So that’s why thimerosal is pretty much harmless in small amounts, and methanol is poisonous, when it’s bigger brother ethanol is a harmless and perfectly legal drug, in small amounts. Anyway, if Dan needs me for a moment of science sometime, you have my e-mail address.

It’s not quite on the level of anti-vax, but I learned recently that Bellingham doesn’t fluoridate its water. Fluoridation measures have been rejected <a href="http://www.npr.org/templates/story/story.php?storyId=5012362"several times, thanks to people like this.

I’m not saying this is the reason why I got a cavity for the first time in my life while living in Bellingham, but…

They say it’s about fluorosilicic acid though, which is nothing like sodium fluoride. Too bad the actual proposition is nowhere to be found. When kept to a reasonable concentration, fluoride ions are perfectly safe. In fact, because calcium fluoride is sparingly soluble, only about a hundredth of a gram per liter, compared to well over a pound per liter for calcium chloride, fluoride ions can actually serve to remove calcium from the water stream. Whether that is to be desired is another thing though, given that the fluoride is added to help teeth, which are after all made of pentacalcium triphosphate monofluoride, if properly fluoridated, and so need calcium to begin with.
