DG model output dose metrics. DG model dose metric output data (in bottom 10 μm) for SiO2, Fe2O3, TiO2 and CeO2 nanomaterials (C 0 = 0.1 mg ml−1, column height = 3 mm, d H = volume-averaged mean (Table 1), reflective boundary condition) from 0 to 120 h. a ENM mass concentration (mg ml−1) and mass deposited per well bottom surface area (mg cm−2). b ENM surface area concentration (cm2 ml−1) and ENM surface area deposited per unit floor surface area (cm2 cm−2). c Particle number concentration (N ml−1) and particle number deposited per unit area (N cm−2)
