Summary

Researchers detected microplastics in human earwax (cerumen) at a high rate among study participants, suggesting earwax may serve as a route through which the body eliminates these particles. The characteristics of the microplastics found in earwax differed from those in the environment, indicating genuine accumulation within the body rather than external contamination. The findings point to earwax as a potential noninvasive way to measure a person's microplastic exposure.

Models

This study provides solid evidence of microplastic presence in human cerumen, suggesting a novel potential route of elimination from the human body. The high detection rate among patients and distinct characteristics of cerumen-borne MPs compared to controls imply genuine human accumulation rather than procedural contamination. Cerumen highlights a promising potential noninvasive bioindicator for assessing microplastic exposure. Further research in larger populations is essential to confirm these findings, elucidate mechanisms, identify polymer types, and explore potential health implications.
