One- and two-box models have been pointed out as useful tools for modelling indoor particle
exposure. However, model performance still needs further testing if they are to be implemented as
trustworthy tools for exposure assessment. The objective of this work is to evaluate the performance,
applicability and reproducibility of one- and two-box models on real-world industrial scenarios. A
study on filling of seven materials in three filling lines with different levels of energy and mitigation
strategies was used. Inhalable and respirable mass concentrations were calculated with one- and
two-box models. The continuous drop and rotating drum methods were used for emission rate
calculation, and ranges from a one-at-a-time methodology were applied for local exhaust ventilation
efficiency and inter-zonal air flows. When using both dustiness methods, large differences were
observed for modelled inhalable concentrations but not for respirable, which showed the importance
to study the linkage between dustiness and processes. Higher model accuracy (ratio modelled vs.
measured concentrations 0.5–5) was obtained for the two- (87%) than the one-box model (53%).
Large effects on modelled concentrations were seen when local exhausts ventilation and inter-zonal
variations where parametrized in the models. However, a certain degree of variation (10–20%) seems
acceptable, as similar conclusions are reached. [-]
