Possible impacts of microplastics and their linked pollutants on the human gut

Microplastics (MPs) are tiny plastic particles measuring less than 5 mm.

• Human exposure to MPs primarily occurs through food intake, which may pose risks to the intestinal tract.
• MPs can compromise intestinal integrity and disrupt the balance of gut bacteria.
• There is evidence that MPs can enter systemic circulation, potentially affecting other tissues in the body.
• MPs can absorb various pollutants, including organic compounds, heavy metals, and marine pollutants, which could enhance their toxicity.
• The interaction between co-pollutants and MPs may lead to dual toxic effects on the intestinal system.
• The exact mechanisms of intestinal damage caused by MPs and their co-pollutants remain unclear.
