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.

Trojan horse in the intestine: A review on the biotoxicity of microplastics combined environmental contaminants

This review examines how microplastics act as 'Trojan horses' by carrying other environmental contaminants such as heavy metals, persistent organic pollutants, and pathogens into the intestinal system. Researchers analyzed the mechanisms by which microplastics adsorb and release these co-contaminants and how the combinations affect the gut barrier. The study highlights that the interactive toxicity of microplastics with other pollutants may be more harmful than either pollutant alone, particularly to intestinal health.

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.

Human Exposure to Microplastics and Its Associated Health Risks

This review examines how microplastics enter the human body through food, air, and skin, and have been detected in stool, blood, and tissues. Research in lab animals and human cells shows that microplastics can disrupt digestion, immunity, the nervous system, and reproduction, and can also amplify the toxicity of other environmental pollutants they carry.

The infiltration of microplastics in human systems: Gastrointestinal accumulation and pathogenic impacts

This review focuses on how microplastics accumulate in the human digestive system and what health problems they might cause. The authors explain that people ingest microplastics through food, water, and air, and these particles may trigger inflammation, disrupt gut bacteria, and potentially contribute to gastrointestinal diseases.

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.

The role of gut microbiota in MP/NP-induced toxicity

This review summarizes how micro- and nanoplastics disrupt gut bacteria and why that matters for overall health. The tiny plastic particles change the composition and function of the gut microbiome, which can trigger inflammation, weaken the intestinal barrier, and potentially contribute to diseases beyond the gut through the immune and nervous systems.

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.

Developments in the field of intestinal toxicity and signaling pathways associated with rodent exposure to micro(nano)plastics.

This review synthesizes current research on how micro- and nano-plastics damage the intestinal epithelium, disrupt gut barrier function, and activate inflammatory signaling pathways. The findings highlight the gut as a primary site of microplastic accumulation and suggest that intestinal toxicity may link dietary microplastic exposure to systemic health effects.

The whole life journey and destination of microplastics: A review

This review traces the full journey of microplastics from their environmental sources through their various pathways into the human body, and what happens once they get inside. Once ingested, microplastics can disrupt gut bacteria, damage the intestinal barrier, and then spread to other organs where they cause inflammation and toxicity. The review highlights significant gaps in our understanding and emphasizes the need for more research on how microplastics move through the body and accumulate over time.

Perturbation of gut microbiota plays an important role in micro/nanoplastics-induced gut barrier dysfunction

Researchers investigated how micro- and nanoplastics disrupt gut barrier function in mice, finding that different surface chemistries caused varying levels of damage. The study suggests that these plastic particles harm the gut by altering the gut microbiome, which then leads to inflammation and weakening of the intestinal barrier that normally keeps harmful substances out of the body.
