Nanoplastics – Implications of Crop Abiotic Stress on Human Food Chain Reported

The abstract of an August 26, 2021 Environmental Science: Nano paper by researchers with Korea Pohang University of Science and Technology, Korea Institute of Toxicology, Korea National Institute of Environmental Research and Korea Institute of Science and Technology reports that “… micro- and nanoplastics … can end up in soil, being considered as a new plant abiotic stressor … it is largely unknown whether and how abiotic stress combination affects the plant uptake of nanoplastics, and how plants tune the rhizosphere interactions to acclimate to a combination of nanoplastic and another abiotic stress. Here we show that smaller, fragmented nanoplastics can accumulate in the root of Arabidopsis thaliana under combined nanoplastic and Cd stresses … Our findings provide critical implications relevant to food security that nanoplastics will contaminate crops as well, and in turn, transfer along the human food chain …” #MicroPlastics #NanoPlastics #PlasticWaste #SingleUsePlastic @KISTKOREA
