There are other sources of mercury that were NOT banned, many with much larger
quantities than tiny photo batteries.  Take for instance fluorescent lights.
Or, as a personal example, I recently purchased a sphygmomanometer .  It
contains about an ounce of pure elemental mercury.  How come that wasn't
banned?  I think banning the batteries was a symbolic gesture and we
photographers were sacrificed on the enviroalter.
