Summary

This review examines the evidence on how nano- and microplastics affect the immune system and intestinal health. The findings suggest that exposure to these particles can disrupt the gut microbiome and impair critical intestinal barrier functions, potentially contributing to the development of chronic inflammatory and immune conditions.

Body Systems

Despite the scarcity of reports directly relevant to human, this review brings together a growing body of evidence showing that nano- and microplastic exposure disturbs the gut microbiota and critical intestinal functions. Such effects may promote the development of chronic immune disorders. Further investigation of this threat to human health is warranted.
