PPT-Mercury toxicity INTRODUCTION 

 Mercury exists in elemental inorganic and organic forms all of which may be toxic The toxic manifestation depends on the form of exposure This topic reviews sources of mercury exposure the clinical manifestations and the treatment and prevention of mercury toxicity. , Venus, .

As seen from the Earth, the angle between Mercury and the Sun at greatest eastern or western elongation can be as large as 28° (when Mercury is near aphelion) or as small as 18° (near perihelion). By contrast, Venus follows a larger, nearly circular orbit with a 224.7-day period. The angle between Venus and the Sun at eastern or western elongation is 47°.. The Totally Terrific T’s.
