Barium is a competitive potassium channel antagonist that blocks the passive efflux of intracellular potassium, resulting in a shift of potassium from extracellular to intracellular compartments. The intracellular translocation of potassium results in a decreased resting membrane potential, making the muscle fibers electrically unexcitable and causing paralysis. Some of these barium's effects may also be due to barium induced neuromuscular blockade and membrane depolarization. (L214)

No indication of carcinogenicity to humans (not listed by IARC).

The health effects of the different barium compounds depend on how well the compound dissolves in water or the stomach contents. At low doses, barium acts as a muscle stimulant, while higher doses affect the nervous system, causing cardiac irregularities, tremors, weakness, anxiety, dyspnea, paralysisand possibly death. Barium may also cause gastrointestinal disturbances, damage the kidneys and cause decreases in body weight. (L214)

Oral (L214) ; inhalation (L214)

Ingesting excess barium may cause vomiting, abdominal cramps, diarrhea, difficulties in breathing, increased or decreased blood pressure, numbness around the face, and muscle weakness. High levels may result in changes in heart rhythm or paralysis and possibly death. (L214)

Nephrotoxin - The chemical is potentially toxic to the kidneys in the occupational setting.

ACGIH Carcinogen - Not Classifiable.

LD50: 250 mg/kg (Oral, Rat) (L273)

Intravenous infusion of potassium often relieves many of the symptoms of barium toxicity. (L214)
