Researchers from the Autonomous University of Barcelona, Spain, have provided insights into how tea bags contribute to daily human ingestion of micro- and nanoplastics (MNPLs). This study confirmed the release of MNPLs from three commercially available tea bags, which all showed varying levels of nano-range particle (NPL) internalization in human intestinal cells.The study, published in the peer-reviewed journal Chemosphere, highlights the release of MNPLs from polymer-based teabags into the aqueous phase during typical usage and underscores the need to understand their toxicological effects on human health.
