ClearAssociation between microplastics exposure and gut microbiota and metabolites in older adults: A cross-sectional study
Researchers analyzed fecal samples from 45 older adults to assess the relationship between microplastic exposure and gut microbiota. They found an average of 70 microplastic particles per gram of feces, primarily PVC, butadiene rubber, and polyethylene, and observed that microplastic exposure was associated with changes in gut microbial diversity and metabolite levels. The study suggests that microplastics may influence gut health in older adults by altering bacterial community composition and metabolic pathways.
Association of gut microbiota composition and function with a senescence-accelerated mouse model of Alzheimer’s Disease using 16S rRNA gene and metagenomic sequencing analysis
This study compared gut microbiota composition between a senescence-accelerated mouse model of Alzheimer's disease and normal aging mice, finding distinct differences in microbial communities and functional profiles. While not directly about microplastics, understanding gut microbiome disruption is relevant to research on how microplastic-associated chemical exposures may affect neurodegenerative disease risk.
Impact of microplastics on the intestinal microbiota: A systematic review of preclinical evidence
Across 28 preclinical studies, microplastics triggered intestinal dysbiosis characterized by increased Firmicutes and Proteobacteria and decreased Bacteroidetes, while increasing gut permeability and elevating pro-inflammatory cytokines including IL-1β, TNF-α, and IL-6.

Researchers investigated the impact of microplastics on human gut microbiota using in vitro gut models, providing early experimental evidence of how microplastic exposure may disrupt intestinal microbial communities. The study offers foundational data on microplastic-microbiome interactions that are difficult to study directly in humans.
Gut microbiome remodeling induced by microplastic exposure in humans
This review synthesizes evidence on how microplastic exposure affects the human gut microbiome, drawing on cross-sectional studies of people exposed through plastic food containers and other sources. Evidence indicates that microplastic exposure is associated with shifts in gut bacteria composition, including increases in certain bacterial groups linked to inflammation. The authors explore potential connections between microplastic-induced changes in gut bacteria and the development of various health conditions.
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.

Gut microbiota, a key to understanding the knowledge gaps on micro-nanoplastics-related biological effects and biodegradation
This review explores how micro- and nanoplastics affect the community of microorganisms living in the gut, and how those same gut microbes might be able to break down plastic particles. Swallowed microplastics can disrupt the balance of gut bacteria, potentially leading to various diseases. On the other hand, some gut bacteria can actually degrade plastics into smaller, less harmful molecules, opening a possible avenue for biological cleanup.
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.
Microplastic-induced alterations in the intestinal environment: Aging as a modulating factor
Researchers evaluated the intestinal toxicity of environmentally aged microplastics compared to commercial microspheres through subchronic oral exposure in an animal model. They found that aging can modify microplastic properties and potentially alter their toxicity in the gut, affecting microbiota composition and inducing oxidative stress and inflammation. The study highlights the importance of using realistically aged particles rather than pristine microspheres in toxicity research.
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.
Association between microplastics and the functionalities of human gut microbiome
Researchers measured five types of microplastics in the blood of 39 adults and then analyzed their gut bacteria using advanced genetic sequencing. They found that microplastic exposure was linked to changes in gut bacteria that could promote infection, including increases in genes related to bacterial invasion and communication. This is one of the first studies to connect microplastic levels in human blood with functional changes in the gut microbiome, suggesting a mechanism by which microplastics could affect overall health.
Polystyrene Accelerates Aging Related-Gut Microbiome Dysbiosis and -Metabolites in Old-Aged Mouse
This mouse study investigated whether polystyrene microplastic exposure accelerates aging-related gut microbiome dysbiosis, using 16S rDNA sequencing and metabolomics. Polystyrene exposure disrupted the gut microbiota composition and altered fecal metabolite profiles in ways consistent with accelerated aging phenotypes.

The microplastic-crisis: Role of bacteria in fighting microplastic-effects in the digestive system
This review examines how microplastics affect the human digestive system and explores whether certain bacteria could help counteract the damage. Microplastics disrupt the gut by altering microbial communities, interfering with digestive enzymes, and damaging the protective mucus lining. The authors highlight the potential for probiotic bacteria to bind to microplastics, reduce inflammation, and help repair the gut environment, offering a possible protective strategy against microplastic-related digestive harm.

Microplastics and their interactions with microbiota
This review examines how microplastics interact with microbiota (the communities of microorganisms in the environment and in living bodies). Microplastics can carry harmful bacteria and disrupt the natural balance of microbial communities in soil, water, and the human gut. The disruption of gut microbiota by microplastics is particularly concerning because a healthy gut microbiome is essential for immune function, digestion, and overall health.
