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.

Are Microplastics Toxic? A Review from Eco-Toxicity to Effects on the Gut Microbiota

This review summarizes existing research on the toxicity of micro- and nanoplastics, from environmental organisms to effects on gut bacteria. Studies show these particles can cause oxidative stress, disrupt energy metabolism, and damage genes in a range of species. With micro- and nanoplastics now found in human blood, lung tissue, and placentas, the authors stress that much more research is needed to understand the full health risks to people.

Impact of micro- and nanoplastics on gastrointestinal diseases: Recent advances

This review summarizes how micro- and nanoplastics can harm the digestive system by causing oxidative stress, inflammation, cell death, and disruption of gut bacteria. These connected pathways can damage the intestinal lining and may contribute to conditions like inflammatory bowel disease and colorectal cancer. The findings highlight the importance of understanding how everyday plastic exposure through food and water could affect gut health over time.

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.

Effect of microplastics and nanoplastics in gastrointestinal tract on gut health: A systematic review.

This systematic review of 30 in vitro studies found that microplastics and nanoplastics cause size- and concentration-dependent damage to human gastrointestinal cells, including increased oxidative stress, mitochondrial dysfunction, inflammation, and apoptosis. Smaller particles consistently showed greater cellular uptake and biological effects, though chronic low-dose exposure generally produced minimal impacts.

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.
