Description of key information
Dustiness testing: Mass median aerodynamic diameter of airborne fraction: MMAD = 116 µm
Geometric standard deviation of MMAD: 116 GSD = 8.1
Particle size distribution: D50 2.06 µm (Laser diffraction)
Additional information
The D10, D50and D90of the particle size distribution of a representative test material are 0.54 µm, 2.06 µm and 6.75 µm, respectively. The total dustiness (airborne fraction) was determined according to method DIN 55992-1:2006 using a modified Heubach dust meter. Total dustiness is 58.09 mg/g. MMAD is 116 µm (GSD 8.1). These were used as distribution parameters for the MPPD model enabling an estimation of deposited dust fractions in the human respiratory tract: These fractions were estimated as follows:
Head (ET): 28.04%
Tracheobronchial (TB): 0.23%
Pulmonary (PU): 0.68%
