Mercury is the most toxic naturally occurring substance on the planet, yet, according to the epa, there is currently over 1 ton of mercury from amalgam fillings in the mouths of americans over 67 million americans exceed the exposure of mercury vapors considered safe by the epa because of the presence of amalgams in their teeth. Mercury is one of the basic chemical elements it is a heavy, silvery metal that is liquid at normal temperatures mercury readily forms alloys with other metals, and.

  • Mercury is an element that can be toxic in various forms, which are tested in different samples: metallic or elemental mercury is a liquid often used in dental fillings, some thermometers, and batteries.
  • Mercury poisoning is a type of metal poisoning due to exposure to mercury symptoms depend upon the type, dose, method, and duration of exposure they may include muscle weakness, poor coordination, numbness in the hands and feet, skin rashes, anxiety, memory problems, trouble speaking, trouble hearing, or trouble seeing high level exposure to methylmercury is known as minamata disease.
