How Is the Toxicity of Barium Sulfate Controlled for X-Rays

Barium sulfate is a radiopaque or contrast agent that blocks the transmission X-rays to help physicians see any special conditions that may exist in an organ or that part of the body where the contrast agent is localized. The areas in which radiopaque agents are located will appear white on X-ray film, creating the needed distinction, or contrast, between one organ and other tissues. How can the toxicity of the barium ion be controlled to provide this necessary radiopaque function  [Pg.17]

The dissolution of barium sulfate in water is described by the reaction BaS04 (aq) = Ba2+ (aq) + SO2- (aq). [Pg.17]

The limited solubility (S, moles per liter) of barium sulfate is reflected in the solubility product for the dissolution. The solubility can be calculated to show that a small amount of barium ion is found free in solution  [Pg.17]

by an application of the common ion effect, the solubility of barium sulfate has been reduced to produce 104-fold less free barium ion in solution, thus further reducing the risk of barium toxicity. [Pg.18]
