Abstract
Microplastics (MPs) were assessed in water and sediment samples along the Salado Estuary, an estuarine system composed of a complex river drainage network in Guayas, Ecuador. MPs were quantified and categorized according to shape, size, and composition. Pellet morphology (237,490 MP/L) and transparent color MPs (252,990 MP/L) were the most common in water, while fragments (27,330 MP/m3) and silver color MPs (25,310 MP/kg) were the most common in solid samples (river sediments, mangrove mud, and sand). MPs made of Polycarbonate, Polyestyrene, and Polypropylene were the most common in all samples. Giving MPs characteristics, likely mapped sources were wastewater from Guayaquil and surrounding towns, boats, and shrimp farms. The samples with the highest MPs were found near Guayaquil, and those with the least were found in the estuary mouth. Monitoring and managing plastic disposal in estuaries are fundamental, as we report a small part of an undocumented issue here.
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.
