Microplastic effects on colon cells, blood lymphocytes, and gut-liver axis

Two in vitro studies analyze plastic particle effects using human cells; find polystyrene (PS) particles change metabolism of human colon cells similar to a carcinogen; PS nanoplastics may have cytotoxic and genotoxic potential on human blood lymphocytes; mouse study indicates microplastics increase risk of insulin resistance; researchers calculate particle ingestion from takeaway containers

Oligomer migration from PET and Tritan™

Scientists find cyclic polyethylene terephthalate (PET) oligomers migrate into fatty food simulants but not olive oil; levels higher from recycled compared to virgin PET; comprehensive extraction and migration experiments of Tritan™ products find oligomer migration from bottles of no toxicological concern but microwaveable containers were non-suitable for food heating
