Nanoplastics – Uptake of Polystyrene Nano Particles by Lettuce and Wheat Plants Studied

The abstract of a January 20, 2022 article in Nature Nanotechnology by researchers with the Chinese Academy of Sciences and Netherlands Leiden University reports that “... There is an urgent need to accurately quantify nanoplastics accumulation in plants. Polystyrene (PS) particles with a diameter of 200 nm were doped with the europium chelate Eu–β-diketonate (PS-Eu), which was used to quantify PS-Eu particles uptake by wheat (Triticum aestivum) and lettuce (Lactuca sativa), grown hydroponically and in sandy soil using inductively coupled plasma mass spectrometry. PS-Eu particles accumulated mainly in the roots, while transport to the shoots was limited (for example, <3% for 5,000 μg PS particles per litre exposure) … The presence of PS-Eu particles in the plant was further confirmed by scanning electron microscopy. Doping with lanthanide chelates provides a versatile strategy for elucidating the interactions between nanoplastics and plants …” #NanoPlastic #PlasticWaste #SingleUsePlastic @UniLeidenNews
