Summary

This book chapter reviews how microplastics interact with inorganic and organic pollutants including heavy metals and organic compounds, via electrostatic interactions, hydrophobic partitioning, and other non-covalent mechanisms. It examines the role of microplastic surface area, functional groups, and aging in facilitating these interactions.

Microplastics can efficiently serve as a vector of several contaminants (heavy metals, organic substances) and transport and migrate in different environments due to the large specific surface area, surface functional groups, and aging. The current chapter comprehensively reviewed the interactions of inorganic and organic pollutants with microplastics. Several mechanisms of interactions, such as electrostatic interactions, hydrophobic interactions, partition, and other non-covalent interactions, are described in detail. Types of inorganic and organic pollutants like manganese, iron, zinc, aluminum, copper, lead, silver, and hydrophobic organic pollutants (e.g., polychlorinated biphenyls, poly-aromatic hydrocarbons, organochlorine pesticides, etc.) are also described comprehensively. Furthermore, several factors affecting these interactions are also discussed.
