Adsorption behaviour and interaction of organic micropollutants with nano and microplastics – A review
This review analyzed the adsorption behavior of organic micropollutants — including pharmaceuticals, pesticides, and industrial chemicals — onto nano- and microplastics, finding that adsorption is governed by pollutant hydrophobicity, particle surface area, and aging state, and that microplastics can act as vectors delivering co-contaminants to aquatic organisms.
Sorption of pharmaceuticals over microplastics’ surfaces: interaction mechanisms and governing factors
Researchers reviewed the sorption mechanisms by which pharmaceuticals interact with microplastic surfaces in the environment. The study found that electrostatic interactions, hydrogen bonding, and hydrophobic forces are the primary mechanisms governing pharmaceutical adsorption onto microplastics, suggesting that microplastics can serve as vectors for transporting pharmaceutical contaminants through ecosystems.
Sorption of pharmaceuticals on the surface of microplastics
Researchers tested the ability of four common microplastic types to adsorb nine pharmaceutical compounds frequently found as water pollutants. They found that sorption involved both hydrophobic and electrostatic interactions, but under natural environmental conditions the binding was relatively weak. The study suggests that while microplastics can interact with pharmaceutical residues, their role as carriers of these contaminants in real aquatic environments may be more limited than previously assumed.

The study suggests that microplastics could act as vectors for certain pharmaceuticals, potentially transporting them through waterways and into organisms.
