Growing concerns over ingested microplastics in humans
Summary
This paper reviews the growing body of evidence showing that microplastics have been found in various human tissues, raising public health concerns. Researchers note that while laboratory studies demonstrate microplastics can cause cellular damage, significant knowledge gaps remain regarding dose-response relationships, specific target organs, and underlying toxicological mechanisms. The study calls for improved detection technologies and thorough risk assessments to better understand the real-world health implications.
Abstract Microplastics have been identified in various human tissues. While laboratory studies have shown that microplastics can cause damage and adversely affect physical functions at multiple levels, significant knowledge gaps persist. These include uncertainties regarding the dose-response relationship, specific target organs, and the underlying toxicological mechanisms. Future research is critical to address public concerns, encompassing the accurate quantification of microplastics through advanced technologies and a thorough risk assessment grounded in an evidence-based framework.
