Ecotoxicological impacts of microplastics to gut microbiota: Response mechanism, challenges and environmental sustainability-A review

This review summarizes how microplastics affect gut bacteria in fish, mice, and earthworms after being swallowed. Microplastics can change the balance of gut microbes and reduce their helpful functions, leading to digestive problems, slower growth, and weakened immunity. Since humans are exposed to microplastics through food and water, these findings raise concerns that our own gut health could be similarly affected.

Microplastic: A potential threat to human and animal health by interfering with the intestinal barrier function and changing the intestinal microenvironment

This review summarizes current research on how microplastics disrupt the gut environment in both animals and humans, focusing on damage to the intestinal barrier. Studies show that microplastic exposure can cause oxidative damage, inflammation, destruction of the gut lining, thinning of the protective mucus layer, and disruption of beneficial gut bacteria. While direct human evidence is still limited, the growing body of animal research suggests that microplastics could pose a meaningful threat to intestinal health.

Impact of microplastics on the human gut microbiome: a systematic review of microbial composition, diversity, and metabolic disruptions

This systematic review of 12 studies found that microplastics including polyethylene, polystyrene, and PVC induce gut dysbiosis in humans, reducing beneficial bacteria and enriching pathogens. Microplastic exposure also impairs short-chain fatty acid production and modulates immune pathways, contributing to intestinal disease, metabolic syndrome, and chronic inflammation.

The ant that may well destroy a whole dam: a systematic review of the health implication of nanoplastics/microplastics through gut microbiota

This systematic review summarizes existing research on how nanoplastics and microplastics disrupt gut bacteria in various organisms. The findings show that plastic particle exposure consistently alters gut microbiome composition, which in turn affects the host's immune function, metabolism, and overall health. These gut bacteria changes may be a key pathway through which microplastics harm human health.

Review: interactions between microplastics and the gastrointestinal microbiome

This review summarizes existing research on how microplastics interact with the gut microbiome in humans, mice, chickens, and aquatic animals. Evidence suggests that gut bacteria can break microplastics into smaller pieces, which may make them more likely to cross the intestinal wall and enter the body. The disruption of the gut microbiome by microplastics is particularly concerning because balanced gut bacteria are essential for immune function, digestion, and overall health.

Oral exposure to polyethylene microplastics alters gut morphology, immune response, and microbiota composition in mice

Researchers fed mice polyethylene microplastics of two sizes commonly found in human stool for six weeks and examined the effects on gut health. The study found that microplastic exposure altered gut structure, disrupted immune cell function, changed gene expression related to inflammation and gut barrier integrity, and shifted the composition of gut bacteria. Mice exposed to both sizes simultaneously showed the most severe effects, suggesting that real-world exposure to mixed microplastic sizes may compound the damage.
