ClearTransport of persistent organic pollutants: Another effect of microplastic pollution?
This review examines how microplastics act as vectors for persistent organic pollutants (POPs) in aquatic environments, covering the physical and chemical factors governing pollutant adsorption and desorption. The authors discuss how interactions between microplastics and POPs vary with polymer type, particle properties, and environmental conditions, and when these interactions may result in toxic effects on aquatic organisms.

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.
Research progress on environmental occurrence of microplastics and their interaction mechanism with organic pollutants
This review summarizes how microplastics in the environment interact with organic pollutants—adsorbing, carrying, and releasing them.

The study highlights the risks these interactions pose to both ecosystem health and human well-being.

This paper examines the role of hydrophobicity in determining whether organic pollutants sorbed to microplastics pose a meaningful additional risk beyond direct water exposure.

Co-occurrence of microplastics and organic/inorganic contaminants in organisms living in aquatic ecosystems: A review
This review examines studies that measured both microplastics and chemical pollutants (organic and inorganic) in aquatic organisms at the same time. A positive correlation was found between microplastic levels and certain pollutants in organisms, suggesting microplastics may help transport contaminants into living things. The findings raise concerns that seafood contaminated with microplastics could also carry higher levels of toxic chemicals into the human diet.
