Comparison of historical (1980s) and contemporary (2023–2024) microplastic contamination of arc clams (Anadara spp.) from tidal flats in Suva, Fiji
Microplastic pollution threatens marine ecosystems, especially in vulnerable regions like the Pacific Islands. This study examines temporal trends by comparing Anadara spp. specimens from Fiji's tidal flats in the 1980s and 2023–2024. Historical samples from the University of the South Pacific's Marine Collection and newly collected specimens were analyzed. Results show microplastic contamination increased from 76 % of 1980s samples (0.42 ± 0.4 particles per individual) to 100 % in 2023–2024 (0.93 ± 0.4 particles per individual).
