For instance, it iswell known that animals get entangled in discarded plastic (Afonso and Fidelis, 2023) andconsume microplastics (plastic particles < 5 mm) while foraging (Ehlers et al., 2021).Examples of microplastic sources comprise everyday single-use items such as plasticpackaging material (Tziourrou et al., 2021), lost or discarded plastic fishing gear (Wuet al., 2023), and tire wear (Goßmann et al., 2021). However, novel microplastic sources,such as weathering polymer-based paints, have only recently been identified (Figure 1A).Even though paints are used in various applications on a regular basis, this source has beenlargely neglected in the past (Gaylarde et al., 2021).
