Microplastics in food: occurrence, source, detection, and perception
Three studies investigate microplastics in foods; review summarizes particle migration from food packaging into honey and calls for universal analysis methods; research study presents analytical method to detect and identify microplastics in certain foods; survey finds public seems unaware of food packaging as microplastic source and seldomly connects microplastics with human health consequences

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
