Mercury in the environment? Students of biochemistry know very well the adverse effects of mercury ions on metabolic processes particularly in the brain. Thus permanently installing lumps of mercury amalgam an inch or two from said brain does not appear to be an entirely sensible procedure irrespective of whether epidemiological studies have, so far, reported adverse effects. Meanwhile cremation releases 2 to 4 grams of mercury per body resulting in the release of at least 3,000 kgm of Hg vapour in the US alone. And yet the ADA, increasingly alone in the world, still supports its use in dentistry. Incredible!
