Microplastics are plastic particles with a diameter of less than 5 mm and more than 1 µm, that are brought to this size by microbial activities, photodegradation or mechanical forces. Nanoparticles are even smaller, with a diameter of less than 1 µm. The term Micronanoplastics considers both groups (Bartkova et al., 2017; Ullah et al., 2021).

Although Micronanoplastics have been extensively studied in aquatic systems, their presence and fate in agricultural systems are still insufficiently understood. They are persistent contaminants that are ubiquitous in the soil environment (Kumar et al., 2020). They are also of particular concern, as the use of plastic materials in agriculture is expected to further increase (Huang et al., 2020).
