Barium is a silvery-white metal which exists in nature only in ores containing mixtures of elements. It combines with other chemicals such as sulfur or carbon and oxygen to form barium compounds. Barium compounds are used by the oil and gas industries to make drilling muds. Drilling muds make it easier to drill through rock by keeping the drill bit lubricated.
Barium concentrations of 20 to 5,000 mg/L were effectively treated in solutions with TDS up to 30,000 mg/ L{9). Below 100 mg barium/L large sulfate-to-barium mole ratios (—90 for 20 mg barium/Lin 27,000 mg/L TDS brine) were required to reduce the barium concentration to 0.5 mg/L in 30 min. However, as the initial barium increased. 5

Barium sulfate is an odorless, white crystalline solid. Used on its own or in tandem with TiO 2 and color pigments, it can bring a range of benefits to the formulation of coatings and the production of plastics. We market two kinds of barium sulfate under the brand names of BLANC FIXE™ and SACHTOPERSE ®. Used in conjunction with TiO 2, our ...
E-Z-HD is a high density suspension for use as a radiopaque agent during X-ray visualisation of the upper gastro-intestinal tract (oesophagus, stomach and duodenum). It is designed for optimal use in double contrast X-ray examinations. E-Z-HD is indicated in adults and children. 4.2 Posology and method of administration.
Barium sulfate (or sulphate) is the inorganic compound with the chemical formula Ba SO 4.It is a white crystalline solid that is odorless and insoluble in water.It occurs as the mineral barite, which is the main commercial source of barium and materials prepared from it. The white opaque appearance and its high density are exploited in its main applications.

Under EPA's 1986 Guidelines for Carcinogen Risk Assessment, barium would be classified as Group D, not classifiable as to human carcinogenicity. Under the Proposed Guidelines for Carcinogenic Risk Assessment (U.S. EPA, 1996), barium is considered not likely to be carcinogenic to humans following oral exposure and its carcinogenic potential ...
Brief Method Summary. Sulfate is precipitated as barium sulfate in a hydrochloric acid medium by the addition of barium chloride. After a period of digestion, the precipitate is filtered, washed with hot water until free of chloride, ignited, and weighed as BaSO 4. Scope and Application.

Severe hypokalemia induced by barium toxicity can cause ventricular dysrhythmias (1-7). Barium sulfate is not absorbed when taken by mouth and therefore is commonly used as a contrast agent for radiographic procedures. Laboratory criteria for diagnosis . Biologic: An elevated urinary barium concentration. A urinary barium concentration greater ...
The key physical and chemical properties of barium compounds are summarized in Table 1.Barium toxicity is mediated through the free barium ion. 1 Exposure to insoluble barium sulfate does not cause significant toxicity because barium sulfate does not release free barium ions that can be absorbed into the lungs or intestine. The available human and animal data 2–4 indicate that barium sulfate ...
