Abstract

Macrolitter pollution risks coastal ecosystems, impacting biodiversity and human activities. This study compares macrolitter composition and abundance in beach and mangrove environments on the Ajuruteua Peninsula, Pará, Brazilian Amazon, an area designated as an Environmental Protection Area (APA). In field research (2021–2024), litter was classified according to material composition. Plastic was the predominant material, comprising 43.78 % of beach litter and 39.66 % of mangroves. Fishing-related litter, such as nets and ropes, represented 23.80 % on beaches and 24.42 % in mangroves, indicating its significant contribution. The density of macrolitter was significantly higher in mangroves (0.89 ± 0.11 kg/m²) compared to beaches (0.10 ± 0.02 kg/m²), demonstrating the impact of tidal retention and dense vegetation. The findings highlight the urgent need for targeted management strategies in mangroves where litter poses ecological risks. Community engagement and improved waste management practices are relevant for preserving the environmental health of Amazonian coastal ecosystems.

期刊介绍： Marine Pollution Bulletin is concerned with the rational use of maritime and marine resources in estuaries, the seas and oceans, as well as with documenting marine pollution and introducing new forms of measurement and analysis. A wide range of topics are discussed as news, comment, reviews and research reports, not only on effluent disposal and pollution control, but also on the management, economic aspects and protection of the marine environment in general.
