In vivo studies have been proving that inhaled barium sulfate (BaSO4) is not deposited in the lung and does not cause biological effects.


Experiments have shown that inhaled BaSO4 is removed again through self-cleaning (clearance, expulsion of mucus, bacteria, and foreign matter from the lung) [1,2,3]. Long-time studies have not been available so far.
