| Abstract: |
Agglomeration and/ or aggregation of the ENM varies with time, medium and particle concentration and is considerably more problematic for "real-world" ENM than for the well-behaved, spherical, and monodisperse materials typically used for method development. Future standardization eff orts must provide sample preparation protocols and analytical methods that are relevant to the complex matrices in which ENM fate and behaviour must be assessed. ENM transformations are modulated by the properties of the matrix (e.g., pH, ionic strength, other components or contaminants) and will alter the transport and bioavailability of the ENM.
