Additional information

Dornhagen, 2013:

Barium sulfide has following particle size distribution:

L50 = 142.6 µm.

L10 = 35.4 µm.

L90 = 789.6 µm.

Parr, Grewe 2013:

Mass median aerodynamic diameter of airborne fraction: MMAD = 28.30 µm (distribution fitted to cascade impactor data).

Geometric standard deviation of MMAD: GSD = 1.53

Total Dustiness (airborne fraction): 66.52 mg/g (experimental results, DMT Report).

Fractional deposition in human respiratory tract (MPPD model, based on calculated MMAD):

Head (ET): 48.25 %

Tracheobronchial (TB): 0.06 %

Pulmonary (PU): 0.01 %
