The average respirable mass-based dustiness of 51 ±
6.3 mg kg-1 places the Pigment Red 149 into the band of moderate
dustiness, borderline to low dustiness.
As far as we know, no fixed bands have been
established for the number-based dustiness index. Comparing to academic
data on other fillers and pigments, the average number-based dustiness
index of 16 ± 1.5 * 104 mg-1 is neither extremely low nor extremely
Consistently with the average values, the size
distribution of the aerosol indicates relatively low agglomeration with
a peak aerodynamic diameter around 1.8 μm.
