Microplastics from disposable paper cups: a growing concern in everyday life
Researchers measured microplastics released from five types of plastic-coated disposable paper cups into hot beverages over 15 minutes, finding that a single 100 ml cup can shed up to 0.7 million HDPE microplastics (primarily 2–5 μm), with routine users potentially ingesting 657–876 million MPs annually.
Identification and characterization of microplastics released during the actual use of disposable cups using laser direct infrared imaging
Researchers found that disposable polypropylene and polystyrene cups release over 1,000 microplastic particles per liter when filled with hot water, with higher temperatures producing more particles. Using a disposable cup three times a day could mean unintentionally swallowing 294 to 402 microplastic particles daily. The study suggests that reusable cups release fewer microplastics and may be a safer choice for regular hot beverage consumption.
Microplastics associated contaminants from disposable paper cups and their consequence on human health
Researchers found that disposable paper cups release microplastic particles and chemical contaminants, including phthalates, into hot beverages within minutes of contact. The interior plastic lining of these cups breaks down when exposed to hot liquids, releasing compounds that can interfere with the hormonal system. The study raises concerns about routine human exposure to microplastics and endocrine-disrupting chemicals through everyday disposable drinkware.
Disposable plastic materials release microplastics and harmful substances in hot water
Researchers tested whether disposable plastic items release particles when exposed to hot water, mimicking everyday use with hot food and drinks. They found that a single exposure to boiling water released over a million submicron and microplastic particles per milliliter from common disposable containers. The study also detected harmful chemical substances in the leachate, suggesting that routine use of disposable plastics with hot beverages poses an underrecognized exposure risk.
Time-dependent release kinetics of nano plastics from disposable cups
Researchers investigated how nanoplastics leach from disposable polystyrene cups over time, characterizing the kinetics of particle release as a function of temperature and exposure duration. The study found that even common single-use cups release nanoplastic particles into beverages, representing a direct human exposure route.
Nanoplastics from disposable paper cups and microwavable food containers
Researchers found that disposable paper cups coated with low-density polyethylene released up to 26 times more nanoplastics than polylactic acid-coated cups, and that hot water exposure substantially increased nanoplastic release from both cup types.
Measurement of Residual Amount of Nanoplastics in vivo from Disposable Paper Cups
This study found that disposable paper cups lined with plastic release nanoplastics into hot beverages and that these nanoplastics can persist in the body. The results suggest that using single-use paper cups for hot drinks is a significant and largely overlooked source of nanoplastic exposure in daily life.
Drinking hot beverages from paper cups: Lifetime intake of microplastics
Researchers quantified the lifetime intake of microplastics from drinking hot beverages in disposable paper cups lined with plastic. They estimated that a person drinking three hot beverages per day from paper cups could ingest tens of thousands of microplastic particles annually, along with associated contaminants like fluoride. The study provides one of the first lifetime exposure estimates for microplastics from this common everyday source.
Time-dependent release kinetics of nano plastics from disposable cups
This study investigated the time-dependent leaching of nanoplastics from disposable polystyrene cups into hot beverages, quantifying particle release as a function of contact duration and temperature. Results showed cups release nanoplastics over time at levels that represent a direct and repeated human ingestion exposure.
Monitoring of microplastics, ions and heavy metals in disposable paper cups from Turkiye marketplaces
Researchers analyzed 10 paper cup brands from Turkish markets for microplastic and heavy metal contamination, identifying MP particles and elevated levels of ions and metals that could leach into beverages.
