Longitudinal cross-section showing microplastic particles inside a birch lateral root in a one-year-old birch tree after being exposed to contaminated soil for 5 months. Clockwise from top left shows cross sections using light microscopy, fluorescence microscopy, and confocal laser scanning microscopy. Arrows point to fluorescing microplastic particles. Inset in bottom right panel shows the area indicated by the arrows in the bottom left panel after enlargement. All images have been enhanced using a contrast and brightness correction. Scales are shown in the bottom right or left corner of the respective image. Image credit: Austen et al., doi: 10.1016/j.scitotenv.2021.152085.
