Exposure to microplastic associated chemicals upon oral consumption of microplastics
AI summary Read the abstract
This thesis quantified the release of plastic-associated chemical contaminants from microplastics during simulated human digestion, measuring how much of these chemicals actually leach out under stomach and intestinal conditions. The research helps estimate the chemical exposure humans receive when they ingest microplastics through food and water.

Release and intestinal translocation of chemicals associated with microplastics in an in vitro human gastrointestinal digestion model
AI summary Read the abstract
Researchers used a lab model of human digestion to test how many toxic chemicals leach out of microplastics collected from beach litter and food packaging, identifying 68 chemicals and 29 metals — some of which crossed a simulated intestinal wall. The findings highlight that microplastics are not just physical particles but chemical carriers that can deliver a complex mixture of harmful substances into the human body.
Desorption of bisphenol A from microplastics under simulated gastrointestinal conditions
AI summary Read the abstract
Researchers investigated bisphenol A desorption from three types of microplastics under simulated gastrointestinal conditions, finding that ingested microplastics can release adsorbed BPA during digestion, posing potential health risks.
Microplastics’ journey into the gut : human exposure to microplastics and associated chemicals
AI summary Read the abstract
This thesis investigates lifetime human exposure to microplastics worldwide and explores how plastic particles act as carriers that transport harmful chemicals into the body after ingestion, known as the vector effect. Using mechanistic models and experimental methods, the work quantifies how much microplastic people consume and how significantly this route contributes to chemical bioaccumulation.
How Digestive Processes Can Affect the Bioavailability of PCBs Associated with Microplastics: A Modeling Study Supported by Empirical Data
AI summary Read the abstract
Researchers used a simulated human digestive model to study whether gut processes change how quickly chemicals like PCBs transfer on and off microplastic particles. They found that digestive enzymes and bile salts significantly accelerated the release of these chemicals from microplastics, suggesting that the human gut environment may increase exposure to plastic-associated pollutants. The study provides new evidence that microplastics could act as carriers that release harmful chemicals more readily during digestion.
Bioaccessibility of Trace Metals and Rare Earth Elements (REE) in Microplastic
AI summary Read the abstract
Researchers measured the bioaccessibility of trace metals and rare earth elements adsorbed onto beach microplastics using simulated digestive fluid conditions. Metals were released from microplastic surfaces under stomach acid conditions, indicating that plastic ingestion can deliver these contaminants to digestive systems of marine organisms and humans.
