A barium
compound such as barium sulfate that do not dissolve well
in water is generally not harmful, and is used as an X?ray
contrast medium. Other salts such as barium chloride which
are water soluble are poisons which result in breathing
problems, increased blood pressure, heart rhythm, brain
swelling, liver?, kidney?, heart? and spleen damage. It
displaces potassium to induce muscle weakness and heart
dysfunctions. It can inhibit calcium absorption, and has
properties similar to lead and cadmium. Exposure can result
from drinking contaminated water, or from industry which
produces paint, bricks, tiles, glass, pesticides, fuel additives
and rubber. Toxic intake is 200 mg and is lethal at 3.7g.
