Summary

This toxicology overview summarizes evidence on the health effects of microplastics in humans and wildlife, covering physical and chemical mechanisms of harm and noting that while animal studies show clear toxic effects, the implications for human health remain uncertain.

Toxicology Microplastics—organic polymer particles smaller than 5 millimeters—have been found throughout the global biosphere. In addition to their effects on wildlife and ecosystems, there is growing concern about whether ingestion of microplastics through drinking water, inhalation, or food can affect human health. In a Perspective, Vethaak and Legler discuss the many unknowns, including exposure levels, whether microplastics can enter cells, and, if they do, what damage might be caused. It is also unclear whether microplastics are contaminated with possible pathogens. Much more research is needed to understand the impact of microplastics on human health. Science , this issue p.
