- Toxicity
- An element; the heaviest of the stable alkaline earths. Barium sulfate is used as a diagnostic aid in radiology due to its radio-opaqueness and, because of its insolubility and lack of absorption, it is safe barring iatrogenic episodes. Poisoning usually results from deliberate or accidental ingestion of soluble barium compounds. The Ba2+ ion is a muscle poison due to the blocking of the K1 channels of the Na+/K+ pump in cell membranes. Because cases of barium poisoning are accompanied by severe hypokalemia, potassium infusion is an effective antidote. The toxicity of barium compounds depends on their solubility, with the free ion being readily absorbed from gastrointestinal tract or lung, whereas the sulfate is essentially unabsorbed. Thus, administration of soluble sulfates immediately after ingestion is another effective antidote.

Use
Barium is found in various alloys, paints, soap, paper, photographic chemicals, explosives, and rubber, and is used in the manufacture of ceramics and glass. Some of its compounds are used as mordants in fabric dyeing and in the preparation of phosphors. One major use is in slurry of ground barite (ZnS + BaSO4) for gas and oil drilling. Barium fluorosilicate has been used as an insecticide, and some barium compounds are used as rodenticides. Medicinally, barium sulfate, being very sparingly soluble, is used as a radiopaque contrast material for X-ray diagnostic purposes and other medical imaging uses.
