Summary

This study evaluated UV-visible spectroscopy and other analytical techniques for quantifying true-to-life environmental nanoplastics, finding that while UV-vis offers a rapid low-cost approach, accuracy depends on particle concentration and sample matrix, underscoring the need for complementary methods for robust nanoplastic quantification.

The growing concern over microplastic pollution has led to increased focus on environmental nanoplastics, which are smaller, more dynamic, and present unique challenges in both quantification and risk assessment.
