Barium sulfate administered intragastrically to albino rats did not produce death until doses administered reached 25 % to 40 % of body weight. These doses produced stomach rupture with death from four to 28 hours or bowel obstruction with death in 28 to 52 hours.
Barium sulfate is a heavy metal with a high atomic number (Z=56) and a K shell binding energy (K-edge of 37.4 keV) very close to that of most diagnostic x-ray beams. Due to these characteristics, barium is an ideal medium for the absorption of x-rays. Barium sulfate is essentially not absorbed from the GI tract nor metabolized in the body.

Jan 01, 1983· The influence of acidity on the rate of formation of the barium sulphate suspension and thus, on sensitivity, was studied with the flow injection system of Fig. 1, without the alkaline EDTA solution. Sulphate standards (20.0-100.0 ppm) were prepared in water, and the R3 reagent was successively 0.1, 0.3, 1.0 and 3.0 M nitric or perchloric acid.
Barium Sulfate deposits have long plagued oil field and gas production operations. The deposition of barium sulfate scale on tubes and vessels can result in plant shutdown, production losses, equipment replacement, and cleaning costs. Barium sulfate scales once formed on the equipment surfaces are extremely difficult to remove.
