Comparison of the effects of different protocols on the particle size distribution of TiO2 dispersions

- Variability in dispersion characteristics of TiO2 nanopowder between protocols was assessed.
- The results highlighted the current comparability problem between many nanoecotoxicology studies.
- Concentration of nanomaterial was the largest source of variation in the protocols studied.
- Nanomaterial sampling and sonication time were also significant factors.
