A new study found microplastics in every human bile sample tested, suggesting the digestive fluid may store plastic particles and potentially extend their presence in the body.

Microplastics were found in every human bile sample analyzed in a new study, raising concerns that the body may retain microscopic plastic particles in a digestive fluid central to fat digestion and toxin removal.
The findings, published in Environmental Science and Ecotechnology and reported by ActivistPost, showed that bile samples collected from patients undergoing gallbladder surgery all contained microplastics. Researchers also found that higher concentrations of the particles were associated with gallstones, a condition that can cause pain, inflammation and digestive problems.
The study suggests the gallbladder and bile ducts may act as storage sites for ingested microplastics, potentially keeping the particles in the body longer than previously understood.
Bile is produced by the liver and plays a major role in breaking down fats and carrying waste products out of the body. But researchers found that the same fluid also accumulates tiny plastic fragments. According to the report, the particles are large enough to interact with human cells and may interfere with energy production, repair processes and normal function.
The bile samples were collected from patients undergoing gallbladder surgery and tested for microplastic contamination. Every sample contained the particles, according to the summaries provided. The most common plastics identified were polyethylene terephthalate, known as PET, and polyethylene, known as PE. PET is commonly used in plastic water bottles, while PE is widely used in packaging.
The available summaries did not provide the number of patients included in the study, the hospital where samples were collected or the specific analytical methods used to detect and identify the particles.
The study adds to previous research showing that microplastics have been detected in human stool, blood and lungs. Earlier findings confirmed that people ingest plastic particles through food, water and dust. Microplastic contamination has also been documented in animals, including a report describing 40 kilograms of plastic found in the gut of a whale.
Researchers said the new findings may point to bile as a secondary reservoir for microplastics after ingestion. Through enterohepatic circulation, bile is released into the intestine and then reabsorbed, a process that could allow microplastics to recirculate and build up over time. That mechanism may help explain how plastic particles persist in human tissues after exposure.
The particles may also carry chemical risks. Microplastics can contain additives and absorb environmental toxins, including chemicals such as DDT and PCBs, which can cling to plastic surfaces. As the particles move through the body, those substances could potentially be released into the digestive system.
Bisphenol A, or BPA, is another concern. BPA is a plasticizer used in many food containers and bottles and can leach into food and beverages, especially when heated. The presence of microplastics in bile raises questions about whether plastic exposure may contribute to gallstone formation or other disorders involving the gallbladder and bile ducts.
The study did not report direct evidence of harm from the particles found in bile. However, the persistence of microplastics in the body was described by outside experts as a concern, and the authors called for more research into whether microplastics in bile contribute to chronic inflammation or other health effects.
Because the liver and gallbladder are central to the body’s detoxification system, researchers said the accumulation of synthetic particles in those organs could have consequences that are not yet fully understood.
The findings underscore the need for standardized methods to measure microplastic exposure and evaluate its long-term effects. Researchers said identifying storage sites such as bile may help scientists better understand the total burden of plastic particles inside the human body.
As global plastic production continues to rise, environmental contamination and human exposure are expected to increase. The study authors said more research is needed to determine the health implications of microplastics accumulating in the body’s detoxification system and to identify ways to reduce exposure.
