Overview

Review evaluates MNP detection challenges and health risks in human samples, suggesting improved methodologies.

Key Points

This review aims to address the analytical challenges in detecting micro- and nanoplastics (MNPs) in human samples and their health implications.
Critical evaluation of sample-preparation strategies and detection methodologies for MNPs.
Comparison of analytical techniques, including microscopy, vibrational spectroscopy, and pyrolysis–gas chromatography–mass spectrometry.
Discussion on the impact of methodological trade-offs on MNP detection accuracy.
Microplastics and nanoplastics were found in various human tissues and biofluids, indicating widespread exposure.
Particles smaller than 10 µm were linked to oxidative stress, inflammation, and potential cellular dysfunction.
Current detection methods are limited by issues like quantification inaccuracies and under-detection of nanoplastics.
