7.2.3 Accumulation of mercury in humans. The presence of raised mercury levels, in it self, does not necessarily cause pathologic reactions - the levels will have to exceed a persons threshold level. Some levels in some children were above those of adults without amalgam, but the mercury levels in both foetuses and children did not, on a group level, exceed the levels of deceased amalgam-bearing adults have. However, some of the children in Drasch's report had mercury levels in their kidneys as high as those of amalgam-bearing adults or children. These subtle effects are defects in psychomotor performance, objectively detectable tremor, and evidence of impair nerve conduction velocity, which are present only in particularly sensitive individuals.
Few persons have higher uptake of mercury reported from their amalgam.
These amounts of mercury can cause intoxication. Mercury is used as preservative in some latex paints. However, usually, not to such high levels that it has been shown to affect normal people. However, if you have a raised sensitivity towards mercury you should know about it, because there is mercury-free latex paint available. If it is so, they are normally not painted on the back side.
