Measuring the Effect of Dietary Microplastic on Biomagnification Potential of Environmental Contaminants and Plastic Additives
Researchers measured the effect of dietary microplastic ingestion on the biomagnification potential of hydrophobic organic contaminants and plastic additives in the gastrointestinal tract, testing competing hypotheses about whether microplastics increase, decrease, or negligibly affect contaminant uptake.
Influence of non-degradable and degradable microplastics on the bioavailability of per- and polyfluoroalkyl substance in mice: Mechanism exploration
Researchers studied how microplastics in food affect the body's absorption of per- and polyfluoroalkyl substances (PFAS), a class of persistent chemicals found in drinking water. They found that high doses of polystyrene microplastics significantly increased PFAS absorption in mice while reducing the amount excreted, essentially making these harmful chemicals more bioavailable. The study suggests that microplastics in the diet could amplify the health risks posed by co-occurring chemical contaminants.
Microplastics in food sold in France: a matter of containers ?
Researchers assessed microplastic contamination in food sold in France, comparing contamination levels across products packaged in different container types to determine whether packaging materials rather than environmental ubiquity represent the primary microplastic exposure route in the French food supply.
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.
Analytical method development and occurrence of microplastics from daily food containers
This study developed and optimized analytical methods for detecting microplastics in food containers and estimated human ingestion through this exposure pathway.

Microplastics in take-out food containers
Scientists collected take-out food containers made from four polymer types in five Chinese cities and detected microplastics in all containers, with fragment counts and polymer compositions varying by container material and city of origin.
Pollutant adsorption on microplastic and its release during digestion processes
Researchers investigated the adsorption of copper and PFAS onto polystyrene, polypropylene, and polyethylene microplastics and examined the subsequent release of these contaminants during simulated digestion processes. The study aimed to clarify the role of microplastics as vectors that increase contaminant bioavailability in marine biota.
Perfluorooctane sulfonate (PFOS) enhanced polystyrene particles uptake by human colon adenocarcinoma Caco-2 cells
Researchers found that the persistent pollutant PFOS significantly enhanced the uptake of polystyrene micro- and nanoparticles by human intestinal Caco-2 cells, suggesting that co-exposure to PFOS and microplastics may increase the risk of particle absorption in the human gut.
Pollutant adsorption on microplastic and its release during digestion processes
Researchers investigated how microplastics act as contaminant vectors for copper and PFAS by adsorbing these substances onto polystyrene, polypropylene, and polyethylene particles and then evaluating their release under simulated gastrointestinal conditions using the Infogest static digestion protocol. They compared adsorption and release across polymer types and particle morphologies (spherical microbeads vs. post-consumer irregular microplastics) to assess how pH, enzymes, and bile affect desorption of these contaminants.
Microplastics in food sold in France: a matter of containers ?
Researchers examined microplastic contamination in food products sold in France, with a focus on whether the type of container — including plastic packaging, cardboard, and glass — influences the level of microplastic contamination in the enclosed food. The study extended prior work focused on salt, water, and seafood to a broader range of food categories, contributing to understanding of how food packaging materials serve as a source of dietary microplastic exposure.
An inverted in vitro triple culture model of the healthy and inflamed intestine: Adverse effects of polyethylene particles.
Using a laboratory model of the human intestinal lining, researchers tested how polyethylene microplastics affect intestinal cells and found they disrupted the barrier function of the gut wall. A compromised intestinal barrier allows larger molecules and particles to pass into the body, which could amplify the health effects of microplastic ingestion.
An innovative in vitro model of IBD to assess micro-/nano-plastics intestinal toxicity.
Researchers developed an innovative in vitro intestinal inflammation model (IBD model) to assess the toxicity of micro- and nanoplastics at realistic concentrations and polymer types, moving beyond the high-dose polystyrene-only studies that dominate current literature.
Impact of food matrices on the characteristics and cellular toxicities of ingested nanoplastics in a simulated digestive tract
Researchers investigated how different food components affect the toxicity of polystyrene nanoplastics as they pass through a simulated human digestive system. They found that fat molecules helped stabilize and disperse the nanoplastics during digestion, increasing their uptake by intestinal cells and worsening cellular damage. The study suggests that the type of food consumed alongside nanoplastic-contaminated items could significantly influence how much harm the particles cause in the gut.

The study found that contaminant properties and water chemistry significantly influence adsorption behavior, confirming that microplastics can serve as carriers for PFAS transport in waterways.
Digestion of microplastics with simulated gastrointestinal conditions mitigates uptake by intestinal epithelial cells: Quantified by imaging flow cytometry
Researchers studied how simulated digestion affects the uptake of microplastics by intestinal cells. They found that microplastics that had been through a simulated digestive process were taken up at significantly lower rates compared to pristine particles. The findings suggest that digestive conditions may reduce how many microplastics actually cross the intestinal barrier, which is important for understanding real-world human exposure.
Take-out containers as nano- and microplastics reservoirs: Diet-driven gut dysbiosis in university students
Researchers analyzed stool samples from 24 university students and found microplastics in every sample, with students who frequently ate from plastic take-out containers having significantly higher levels. The most common plastic type was PET, likely from food packaging. Higher microplastic levels were associated with changes in gut bacteria composition, suggesting that everyday habits like eating take-out food could disrupt gut health through microplastic exposure.
