Role of combinatorial environmental factors in the behavior and fate of ZnO nanoparticles in aqueous systems: A multiparametric analysis

- ZnO NP aggregation and dissolution were investigated in combinatorial systems.
- Effects of six co-varying factors were assessed by a multivariate approach.
- Organic acid concentration was the most influential factor in aggregation.
- NP concentration and pH had minor effects on aggregation in these systems.
- NP dissolution was greatly influenced by electrolyte type and NP aggregation.
