Schematic representation of sources, sinks, and pathways of microplastic transport in the environment: from manufacture to the ocean. Rectangle shapes represent major sources, oval shapes represent major sinks, if underlined it represents a major transport pathway, and black arrows show the fluxes between the different compartments. “*” signifies degradation of microplastics via fragmentation. “^” and “#” signifies adsorption and desorption of organic pollutants from microplastics, respectively. “?” represents an area where there is a significant knowledge gap. “?” are put after what is unknown, i.e., if sorption data is missing, the “?” will follow the “^” or “#”.
