Oral study: Hydrodynamic number size distribution of NM-101/NM-102/NM-103/NM-104 of the suspended TiO 2 particle preparations used for oral gavage (A: results for particle size 0–250 nm; B: results for particle size 0–3000 nm). The majority of particles were observed as agglomerates/aggregates between 50–200 nm. Suspensions of NM-101 and NM-102 contained an additional mode between 250 and 2500 nm. No agglomerates/aggregates were observed above 3 μm. Results are the mean of 12 analyses conducted on two separate days.
