Barium compounds that do not dissolve well in water are not generally harmful and are often used by doctors for medical purposes. The results indicate that 4-22% of the cyanide leached out of the column as free or complex cyanide, while 4 to 11% of the added cyanide remained in the column, probably as Prussian blue. . Barium bromate. The most common minerals of barium are baryte (barium sulfate, BaSO 4) and witherite (barium carbonate, BaCO 3).The name barium originates from the . Cadmium contamination from pipes and fittings can be more of a problem when the water is acidic and low in dissolved solids. In the surface water pathway, the HWIR modeling scenario includes several transport processes that require metal partition coefficients: (1) The overland transport of metal contaminants in runoff water in the watershed and the consequent partitioning between soil and water; (2) partitioning between Barium: Occurs naturally in some limestones, sandstones, and soils in the eastern United States.
