Resumen: Micro- and nanoplastics (MNPs) are accumulating worldwide, posing a threat to ecosystems and biodiversity due to the ongoing global demand. In the literature there is a wide variety of procedures for sampling and characterizing MNPs in water samples, highlighting a lack of standardized methods, particularly plastics in the nanometric range (<0.1 μm), which require the removal of larger particles (>1.0 μm) followed by a concentration step to reach the quantification limits of analytical techniques. Proper sampling is essential for collecting representative samples, followed by a pre-treatment to remove suspended particles, which may interfere in the subsequent analysis. Consequently, specific techniques are employed to isolate the MNPs from the matrix samples and proceed to visual and chemical characterization. This review compiles key data on MNP characterization and advocates for a “best practices” toolbox to overcome current challenges, proposing a conceptual framework for developing efficient MNP characterization and supporting potential decontamination technologies.
