Small micro- and nanoplastic test and reference materials for research: Current status and future needs
This review highlights the critical shortage of well-characterized, environmentally relevant reference materials for studying small microplastics and nanoplastics. Most laboratory studies use commercially available spherical particles that do not represent the irregular, weathered particles found in nature. The authors call for developing standardized reference materials that better mimic real-world microplastic contamination to improve the reliability of exposure and hazard assessments.
