Amalgam (dentistry) exposure", studies on whether there exist "potential gender differences" or "genetic basis for sensitivity to mercury exposure." The removal of amalgam fillings is not recommended for reasons other than a true hypersensitivity to mercury. Mercury levels in blood and urine have been shown to rise for a short period of time following the removal of amalgam restorations and no studies have demonstrated any health gain from restoration removal. Removal involves exposure to mercury vapor released during the removal process. Amalgams also contribute to mercury toxicity in the environment. With regards to amalgam placement and removal in pregnancy, research has not
Organosilver chemistry η-alkene complex. Silver is also present in other carbon-carbon bond skeletal rearrangements such as the quadricyclane to norbornadiene rearrangement, the cubane to cuneane rearrangement and the rearrangement of the cyclobutadiene dimer to cyclooctatetraene. Organosilver chemistry Organosilver chemistry in chemistry is the study of organometallic compounds containing a carbon to silver chemical bond and the study of silver as catalyst in organic reactions. In the group 11 elements silver is the element below copper. The chemistries have much in common but organosilver catalysis is much less common (mostly academic study) than organocopper chemistry due both to the relatively high price of
