Classification of marine microdebris: A review and case study on fish from the Great Barrier Reef, Australia

Abstract Marine debris, and in particular plastic pollution, is ubiquitous throughout global marine environments. Here, we present a classification of marine microdebris (i.e. debris between 0.1 μm and <5 mm) tailored to represent synthetic, semi-synthetic and naturally-derived items. The specifi...
