Evidence of elevated microplastic accumulation in Pacific Island mangrove sediments.

Although microplastics (MPs) in the environment are well-reported, there is a geographical research gap, particularly in Pacific Island Countries and Territories. Recognising the critical role mangroves play in regulating the exchange of sediment and pollutants between land and ocean, we conducted research in Fiji to compare levels of sediment MPs within mangroves with those in surrounding sediments, and to assess differences between urban and rural areas. MPs were found to be significantly higher in sediments collected inside the mangroves (13.

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.
