[QUOTE="user 4386, post: 657865, member: 4386"] Yes.minimata disease was caused by methyl mercury (directly released by industry, although bacteria convert metallic mercury to native mercury in streams). It was ingested by eating fish, not drinking water (negligible solubility in water). Even some fish sold in Australian shops can have enough mercury to cause birth defects (mostly big predators like shark and swordfish, tuna and bass). No, amalgam or native mercury are unlikely to have any significant methyl mercury attached. You won't recognize it but it is likely to be extremely low where gold and native mercury metal accumulate in streams - far more likely in organic-rich muds. Most modern thermometers do not contain mercury, but coloured alcohol, although thermometers that contain any liquids are rare nowadays (surprised if still used in science labs). [/QUOTE]
