Fate of Barium Sulfate Nanoparticles Deposited in the Lungs of Rats. [PDF]
Sci Rep, 2019 We have shown that barium [from BaSO4 nanoparticles (NPs)] was cleared from the lungs faster than other poorly soluble NPs and translocated mostly to bone. We now studied barium biokinetics in rats during Study 1: two-year inhalation exposure to 50 mg/m3
