Microplastics (MPs) – Concentration in World Ocean Sediment Estimated at 14 Million Tons

According to a report published October 5, 2020 in Frontiers in Marine Science by researchers with the Australian Commonwealth Scientific and Industrial Research Organization and others “…we still know relatively little about how much plastic pollution has found its way into the deeper areas of the world’s oceans … we quantified microplastics in deep-sea sediments from the Great Australian Bight ... We found substantially higher microplastic counts than recorded in other analyses of deep-sea sediments. Overall, the number of microplastic fragments in the sediment increased as surface plastic counts increased, and as the seafloor slope angle increased … microplastic counts were highly variable … we extrapolated from our empirical data to provide a conservative global and mass of MPs on the seabed floorwe conservatively estimate 14 million tonnes of microplastic reside on the ocean floor …” #MicroPlastics #PlasticWaste #SingleUsePlastics
