Interactions of microplastics in aquatic environments: what do we know so far?
Microplastics are widespread environmental contaminants that have been detected in a wide range of ecosystems globally. Upon entering aquatic environments, microplastic particles interact with their surroundings in a variety of ways. In particular, aquatic microorganisms can adhere to microplastic surfaces and form biofilms that alter their physico-chemical properties. Microplastics can also bind to biotic surfaces and have negative effects on the organisms to which they adhered. On the other hand, they are in contact with other environmental pollutants, which facilitates their adsorption and consequently increases their bioavailability. The complexity of these interactions is influenced by numerous factors, particularly the characteristics of the microplastics, which vary greatly in terms of size, shape, morphology, and chemical composition. Understanding these complex interactions is crucial for assessing their ecological risks and developing effective management strategies.
