The physicochemical properties and environmental risks of microplastics-natural organic matter (MPs-NOM) composite pollutants, which are formed by the interaction between MPs and NOM, are complex and variable. Considerable research has been conducted on the hazards of MPs and NOM, as well as strategies for their removal. However, most studies have focused on the trends of the two components in isolation, neglecting the contribution of interfacial interactions and synergistic hazards, which may lead to an underestimation of their environmental risks. Therefore, this review systematically describes the research progress on MPs-NOM composite pollutants in water, focusing on the interactions, environmental hazards, and efficient removal methods. Furthermore, future research directions are proposed from the perspectives of mechanism revelation, risk assessment, and technological innovation. The mechanisms underlying the formation, fate, and removal of MPs-NOM pollutants throughout the entire process should be strengthened to provide a scientific basis for upgrading water treatment technologies aimed at addressing new pollutants.
