ClearMicroplastics and health hazards: gastrointestinal risk assessment across a multi-species perspective
This review assesses the gastrointestinal health risks of micro- and nanoplastics across multiple species, from aquatic organisms to mammals, examining how these particles interact with the digestive system. Researchers found that microplastics can cause gut inflammation, alter the microbiome, and potentially cross the intestinal barrier into other tissues. The study highlights that understanding effects across species can help predict potential risks to human digestive health.

Microbial risks associated with microplastics in the food chain and possible control measures (literature review). Part 1. Dietary intake and influence on the gut microbiota
This review summarizes evidence that microplastics commonly found in food and drinking water can disrupt the human gut microbiome when ingested. Studies show that microplastics alter the composition and function of intestinal bacteria, potentially affecting digestion, immunity, and overall health. Since a healthy gut microbiome is essential for human wellbeing, this pathway of harm deserves attention alongside other known risks of microplastic exposure.

Micro(nano)plastics in food system: potential health impacts on human intestinal system.
This review assessed how micro(nano)plastics in the human food system reach the intestine and accumulate in the gut, summarizing evidence that they can alter intestinal barrier function, trigger inflammation, and disrupt the gut microbiome, with implications for long-term digestive health.
Gut microbiota as an emerging target for the health implications of microplastics
This review examines how microplastic exposure disrupts the gut microbiome, finding evidence that microplastics damage intestinal barrier proteins, promote inflammation and oxidative stress, and may drive systemic effects including neurotoxicity and reproductive toxicity through gut-mediated pathways.
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.
Micro(nano)plastics and Their Potential Impact on Human Gut Health: A Narrative Review
This review summarizes research on how micro- and nanoplastics affect the gut, finding that they can damage the intestinal lining, trigger immune responses, and disrupt the balance of beneficial gut bacteria in both cell studies and animal models. Since humans are primarily exposed to microplastics through food and food packaging, understanding these gut effects is essential for assessing the true health risks of plastic pollution.
Effect of microplastics and nanoplastics in gastrointestinal tract on gut health: A systematic review.
This systematic review provides the first comprehensive look at how microplastics and nanoplastics affect the human gut using laboratory models. The findings help explain how these tiny particles may damage the digestive tract lining and trigger inflammation, which is important for understanding the health risks of swallowing microplastics in food and water.
Micro(nano)plastics and their potential impact on human gut health: a narrative review
This narrative review synthesizes evidence on how microplastics and nanoplastics affect the human gut, discussing ingestion routes, gut barrier interactions, microbiome disruption, and potential systemic health effects.
How do microplastics affect the composition and function of gut microbiota?
Researchers reviewed how microplastics may disrupt gut microbiota composition and metabolic function, noting that while dysbiosis is a likely outcome of exposure, the full scope of these effects in humans remains understudied.
How do microplastics affect the composition and function of gut microbiota?
Researchers reviewed how microplastics may disrupt gut microbiota composition and metabolic function, noting that while dysbiosis is a likely outcome of exposure, the full extent of these effects in humans remains poorly characterized and understudied.
Toxicological Evaluation of Effects of Some Environmental Pollutants on Intestinal Microbiota: Traditional Review
This review examines how various environmental pollutants affect the gut microbiome — the community of microorganisms in the intestinal tract. Microplastics are among the pollutants discussed, and their ability to alter gut microbiota composition is increasingly recognized as a mechanism by which plastic particles may harm human and animal 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.
A Comprehensive Narrative Review of Potential Gastrointestinal Adverse Effects From Micro(nano) Plastic Exposure

Effects of Microplastic on the Gastrointestinal Tract and Gut microbiome of Sprague Dawley Rats
Adult male rats were fed polyethylene microplastics mixed with standard food for 24 days to assess effects on gastrointestinal tissue histology and gut microbiome composition. Microplastic exposure caused histological changes in the gastrointestinal tract lining and altered gut microbial diversity, providing direct evidence that oral microplastic ingestion disrupts gut health in mammals.
Immunotoxicity and intestinal effects of nano- and microplastics: a review of the literature

This review explores how microplastics interact with microorganisms in the environment and within the gut, examining implications for both animal and human health. Researchers found that microplastics can alter gut microbiota composition, promote the spread of antibiotic-resistant bacteria, and amplify the toxicity of other environmental pollutants. The study suggests that the interaction between microplastics and gut microorganisms is an important emerging area for understanding health risks.
Relevance of gut microbiome research in food safety assessment
This review examines evidence that food additives and microplastics may disrupt the gut microbiome and, in turn, affect human health.
