Description of key information

The median particle size D 50 of the test items deduced from the particle size distribution is 897.2µm.

The  particle size D 10 of the test items deduced from the particle size distribution is 440.3µm.

The  particle size D 90 of the test items deduced from the particle size distribution is 1491.2µm.

Total Dustiness (airborne fraction): 0.40 mg/g (experimental results, DMT Report). Mass median aerodynamic diameter of airborne fraction: MMAD1 = 11.24 µm and MMAD2 = 11.51 µm. Geometric standard deviation of MMAD: GSD1 = 4.01 and GSD 2 = 1.61. Fractional deposition in human respiratory tract (MPPD model, based on calculated MMAD):

Head (ET): 76.6%

Tracheobronchial (TB): 1.0%

Pulmonary (PU): 1.9%
