Description of key information

Additional information

Granulometry (Regius, 2012)

Divanadium tris(sulphate) has a median particle size L50 = 524.62 µm as measured by laser diffraction measurement. and following particle size distribution:

D10 = 34.63 µm

D50 = 524.62 µm

D90 = 1313.28 µm

Dustiness (Parr & Grewe, 2013)

Total Dustiness (airborne fraction) of divanadium tris(sulphate): 1.36 mg/g (DMT)

Mass median aerodynamic diameters (mono-modal distribution) of airborne fraction: MMAD = 36.69 µm (distribution fitted to cascade impactor data).

Geometric standard deviation of MMAD: GSD = 1.47.

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

Head (ET): 33.24 %

Tracheobronchial (TB): 0.01%

Pulmonary (PU): 0.00%
