Sources, distribution and fate of microfibres on the Great Barrier Reef, Australia

A comprehensive study on the Great Barrier Reef reveals widespread contamination with microdebris, primarily microfibres, which constitute 86% of detected items. The research highlights non-random intake patterns of microdebris by coral reef fish, differing significantly in chemical composition, shape, and colour from that found in surface waters. Additionally, riverine discharge is identified as a likely source for inshore microdebris contamination but not for offshore locations. This study underscores the complexities in determining marine microdebris exposure and fate, providing critical insights to improve ecological assessments and prioritize source reduction efforts.
