Description of key information

Mass median aerodynamic diamater of airborne fraction: MMAD = 16.29 µm.
Geometric standard deviation of MMAD: GSD = 3.27 µm.
The particle size distribution of the pigment Pyrochlore antimony lead yellow was determined using a MALVERN laser diffraction equipment (Béltran 2013). The size distribution was calculated using the MIE theory in order to interpret the light scattering signal collected by the detectors.
The following values were calculated assuming that the particles are spherical:
d10 = 1.2 µm
d50 = 5.4 µm
d90 = 17.8 µm
