The evidence indicates that microplastics may move up the food chain and ultimately reach humans, though the full extent of health risks remains under investigation.
Microplastics in Human Tissues: Sources, Distribution, Toxicological Effects, and Health Implications
Researchers reviewed the growing body of evidence that microplastics accumulate in human tissues — including lung, blood, placenta, breast milk, and heart tissue — where they can trigger inflammation, oxidative stress, and cell death. The review highlights urgent knowledge gaps around how plastic particles move through the body and what their long-term health effects may be.
Adverse Outcome Phenomena and Toxicity Mechanisms of Micro and Nanoplastics in Human Health
This review examines the growing evidence that micro- and nanoplastics can enter the human body through food, water, and air, and may contribute to harmful biological effects.
