Microplastics Found to Move from Soil to Lettuce into the Food Web

The abstract of an October 22, 2022 NanoToday article https://www.sciencedirect.com/science/article/pii/S1748013222002390 by researchers with the University of Eastern Finland, Netherlands Leiden University, Netherlands National Institute of Public Health and the Environment (RIVM), and UK University of Birmingham reports that the researchers “… show that lettuce takes up 250 nm gadolinium labelled polystyrene (PS) and polyvinyl chloride (PVC) SMPs from the soil. The polymer type influences the biodistribution of the particles in lettuce (roots and leaves) and the number of particles transferred from the plants to insects feeding on the treated lettuce. The SMPs were further transferred from insects to insect-feeding fish to accumulate mostly in the fish liver ... No biomagnification in fish was detected for either type of SMPs. We conclude that plastic particles can potentially transfer from soil into food webs and the chemical composition of plastics influences their biodistribution and trophic transfer in organisms …” #MicroPlastics NanoPlastics #PlasticWaste #SingleUsePlastic @UniEastFinland
