Plastic Teabags Release Billions of Microparticles and Nanoparticles into Tea

“Plastic Teabags Release Billions of Microparticles and Nanoparticles into Tea” is a September 25, 2019 article published in the ACS journal Environmental Science and Technology. In this American Chemical Society publication by researchers with McGill University in Montreal, Quebec, Canada, they report that “The increasing presence of micro- and nano-sized plastics in the environment and food chain is of growing concern”. The authors “show that steeping a single plastic teabag at brewing temperature (95 °C) releases approximately 11.6 billion microplastics and 3.1 billion nanoplastics into a single cup of the beverage … The levels of nylon and polyethylene terephthalate particles released from the teabag packaging are several orders of magnitude higher than plastic loads previously reported in other foods. An initial acute invertebrate toxicity assessment shows that exposure to only the particles released from the teabags caused dose-dependent behavioral and developmental effects …”
