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

Studies investigate extractable and leachable FCCs, present collision cross section database

Scientists develop collisions cross section (CCS) database for leachable and extractable food contact chemicals (FCCs) to help in chemical identification during targeted and untargeted analysis; database covers 1038 CCS values; study tentatively identifies >100 migrants from 24 plastic food packaging articles including 11 that are of potential concern or are priority hazardous substances
