Comparison of Microplastic Pollution in Beach Sediment and Seawater at UNESCO Can Gio Mangrove Biosphere Reserve.

ABSTRACT: Microplastics have become a global concern due to their persistent properties and impacts on the marine environment. This research investigates pollution sources and behaviors of microplastics at UNESCO Can Gio Mangrove Biosphere Reserve. Density flotation with sodium chloride is employed to extract microplastics from sand at Can Gio Beach, and a double-filtration procedure is developed to recover microplastics from seawater at the beach and Dong Tranh Cape. The microplastics' morphology and type are analyzed by micro-Raman spectroscopy. The results show that microplastics are accumulated at concentrations from 31.99 to 92.56 MPs g^-1 at various sand layers. The seawater at Can Gio Beach and Dong Tranh Cape contains 6.44 and 3.75 MPs L^-1 of microplastics, respectively.
