The indiscriminate use of plastics has led to their presence as waste across virtually the entire planet. This material fragments into small pieces, known as microplastics (MPs), which easily disperse. In aquatic environments, MPs are widely distributed and can interact with other pollutants, such as cadmium (Cd), a metal that is toxic even at low concentrations. The adsorption of Cd onto MPs facilitates its entry into organisms that accidentally ingest them, which could amplify its toxicity due to a synergistic effect. Although this interaction has the potential to cause greater harm to the health of organisms, it has been little studied. This paper aims to provide a synthetic review of recent research on the interaction and effects of Cd and MPs on aquatic organisms.
