Microplastics: An introduction to environmental transport processes

TLDR

Microplastic pollution is widespread across land, water, and air, and these environments are closely linked rather than independent. The review aims to overview sources, fate, and transport of microplastics and introduces a new Plastic Cycle concept to better understand flux and retention across environmental matrices. The authors review existing knowledge on microplastic sources, fate, and transport and propose a Plastic Cycle framework to model flux and retention across matrices. Understanding microplastic processes enables assessment of exposure and better determination of long‑term ecological and human health implications.

Abstract

Microplastic pollution is widespread across the globe, pervading land, water, and air. These environments are commonly considered independently, however, in reality these are closely linked. This review gives an overview of the background knowledge surrounding sources, fate and transport of microplastics within the environment. We introduce a new “Plastic Cycle” concept in order to better understand the processes influencing flux and retention of microplastics between and across the wide range of environmental matrices. As microplastics are a pervasive, persistent and potentially harmful pollutant, an understanding of these processes will allow for assessment of exposure to better determine the likely long‐term ecological and human health implications of microplastic pollution.
