Wicked sad part is, that we can't let the kids eat any freshwater fish in NH, since the mercury levels are so high from the mid-west coal power plants. Trust me when I say I'm no tree hugger, but I remember eatin' what I caught as a kid, and this really ticks me off. Have to release everything we catch! But at least they can say they caught'em.
At one point, in a past life I was on a mercury spill response team, where we would use copper powder to soak up the mercury and create an amalgam. Now the thought has crossed my mind about the copper coins I collect out of the lakes, has any mercury bonded to the corroded surface of the copper? Don't know, I'm not a chemist, but it does give me pause at times.
