Micro(nano)plastic and per- and polyfluoroalkyl substances in soil/sediment¿water ecosystems: sources, transport, interactions, and challenges Academic Article in Scopus uri icon

abstract

  • This article provides an overview of the contamination of micro(nano)plastics and per- and polyfluoroalkyl substances (PFAS) and their behavior in natural environmental settings. Interaction between micro(nano)plastics and PFAS is governed by functional groups, polarity, crystallinity, surface area, surface morphology, size, solution chemistry (i.e. pH, salinity, and organic matter), aging, and biofilm. Micro(nano)plastic adsorbs long-chain PFAS primarily via strong hydrophobic attraction (hydrophobic C¿F chain tail of PFAS molecule), strong electrostatic attraction due to short-chain PFAS, and pore filling (high quantities of mesopores). Finally, this paper concludes the co-transport and enrichment of micro(nano)plastics and PFAS in sediments and aquatic environments. © 2025 Elsevier Ltd
