To the Editor, I read with great interest the article by Guo et al. [1], entitled “Discovery and analysis of microplastics in human bone marrow” (Journal of Hazardous Materials, 477, 135266), which represents a pioneering effort to demonstrate the presence of microplastics (MPs) in human bone marrow. While this work contributes valuable early insight into human internal MP exposure, several methodological inconsistencies require clarification to ensure the scientific robustness and reproducibility of the findings.
