Importance of Attachment Efficiency in Determining the Fate of PS and PVC Nanoplastic Heteroaggregation with Natural Colloids Using a Multimedia Model.

ABSTRACT: Here, we assessed the heteroaggregation of polystyrene (PS) and poly(vinyl chloride) (PVC) nanoplastics with SiO₂ as a model of natural colloids. Homoaggregation and heteroaggregation were evaluated as a function of CaCl₂ (0-100 mM) and natural organic matter (NOM) (50 mg L^-1) at a designated concentration of nanoplastics (200 μg L^-1). Critical coagulation concentrations (CCC) of nanoplastics were determined in homoaggregation and heteroaggregation experiments with SiO₂ and CaCl₂. The attachment efficiency (α) was calculated by quantifying the number of nanoplastics in the presence of CaCl₂, NOM, and SiO₂ using single-particle inductively coupled plasma mass spectrometry (spICP-MS) and pseudo-first-orde
