Re: Sweden nuke thread vs. Mercury in coal airborne impacts

["Tom Savin" <lexicon@hotbot.com>]

 Interesting note - pike are one of the few fish that can survive in water that is pH 4.0-4.5, is it that they can survive higher levels of mercury too? A lower pH aids in solubilizing heavy metals.  One might be able to tie this in with acidic rain.
