Implication

Study demonstrates sedimentation patterns vary with particle size and metal cations in aquatic environments, suggesting implications for microplastic distribution.

Key Points

This research aims to understand how particle size and environmental constituents influence microplastic sedimentation behavior.
Investigated effects of metal cations (Na+, Ca2+) and humic acid on polystyrene particles (100 nm, 500 nm).
Conducted DLVO analysis to assess aggregate stability based on particle size and ion valence.
Evaluated aggregation-settling patterns in environmental water samples.
Larger polystyrene particles (500 nm) showed lower critical coagulation concentration and greater aggregation tendency.
Smaller polystyrene particles (100 nm) demonstrated a two-stage behavior of settling and floating due to increased ion adsorption.
Dissolved organic matter composition significantly influenced aggregation and settling, with protein-like DOM enhancing these processes.
