Dustiness (airborne fraction): total: 55.23 mg/g.
In the original study report by DMT, a calculation of the mass median diameter was not conducted. Since the deposited fractions were provided for each of the cascade impactor stages, it was possible to fit a mono modal lognormal distribution to the databy standard non-linear regression procedure. As a result, the MMAD and GSD of total dustiness (airborne) fraction are calculable and reported (MMAD = 32.58 µm, GSD = 1.52). As the cascade impactor already takes aerodynamic characteristics of the particles into account, the reported mass median diameter can be interpreted as the mass medianaerodynamicdiameter.
This figure and the corresponding GSD 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): 40.3%
Tracheobronchial (TB): 0.0%
Pulmonary (PU): 0.0%
