Microplastics in foodstuffs come into close contact with the gastrointestinal tract and have the potential to interact either physically or chemically with the cells there. A study published in Chemosphere in April 2024 by Ekaterina Brynzak-Schreiber of the University of Vienna and co-authors explored how polystyrene micro- and nanoplastics (PS-MNPs) interact with colon cancer cells, focusing on how particle size affects uptake and distribution within the cells and their subsequent behavior.
