Nanoplastics – Single Use Hot Beverage Cups Release “Trillions” during Normal Use

The abstract of an April 20, 2022 Environmental Science and Technology article by researchers with the US National Institute of Standards and Technology reports that “… commonly used consumer products such as single-use food grade nylon bags and hot beverage cups lined with low-density polyethylene release nanometer-sized plastic particles … when exposed to water. The number of particles released was a function of the initial water temperature (high temperature vs ambient) for each of the tested materials. Mean particle diameters were between 30 and 80 nm with few particles >200 nm. The number of particles released into hot water from food grade nylon was 7 times higher when compared to single-use beverage cups. On a particle number density basis, particles released into water from a single 300 mL hot beverage cup equate to one particle for every seven cells in the human body in a size range available for cellular uptake …” #PlasticWaste #SingleUsePlastic #MicroPlastics #NanoPlastics @NIST
