What Influences the Mobility of Nanomaterials in Aquatic Systems?
The mobility of nanomaterials in aquatic systems is influenced by several factors:
Particle Size: Smaller particles generally have higher mobility due to their lower sedimentation rates. Surface Charge: The charge of nanomaterials can affect their interaction with other particles and natural organic matter. Aggregation: Nanoparticles tend to aggregate, which can reduce their overall mobility. Water Chemistry: Factors such as pH, ionic strength, and the presence of natural organic matter can significantly influence nanoparticle behavior.
