Microplastics in take-out food containers

Back to Resource Library

Abstract: “Microplastics have been detected in various media including water, sediment, and seafood, whereas there are few studies focusing on microplastics in take-out containers. In this study, scientists collected take-out containers made of common polymer materials (polypropylene, PP; polystyrene, PS; polyethylene, PE; polyethylene terephthalate, PET) from five cities in China. Microplastics in the containers were analyzed after different treatments (direct flushing and flushing after immersing with hot water). Results showed that microplastics were found in all take-out containers, and come from atmospheric fallout and flakes from container’s inner surfaces. Based on the microplastic abundance in take-out containers, people who order take-out food 4–7 times weekly may ingest 12–203 pieces of microplastics through containers.”
