TLDR
In this paper, the discovery of microplastic in sediment from the sea of western Sumatra at a depth more than 2000 m, indicated that plastic, considered new developed materials (early nineteen centuries made), has invaded marine areas, including pristine areas.Abstract:
Indonesia was recently ranked second on the list of countries producing plastic waste. Plastic can be degraded by thermal oxidation either with ultraviolet radiation and by mechanical to a very small size the size will be smaller. Degraded plastic with small sizes (<5 mm) measured has been micrometers known as microplastic. We took sediment samples on 07-18 May 2015 in EWIN 2015 cruise, which part of the contribution of Indonesian researchers for the International Indian Ocean Expedition-2 program, at 66.8 to 2182 m below sea level. Microplastic analysis from the sediment was carried out by using flotation methods. We found microplastic in 8 locations out of 10 sampling locations. We found 41 particles microplastic with a form of granules (35 particles) and fibers (6 particles). Most of microplastic particles were found at depths less than 500 m with 20 particles. The discovery of microplastic in the sediment from the sea of western Sumatra at a depth more than 2000 m, indicated that plastic, considered new developed materials (early nineteen centuries made), has invaded marine areas, including pristine areas. It confirms the statement that plastic waste has spread widely to different areas of the seas and oceans, including remote and mostly unknown areas such as the deep sea.read more

TL;DR: This study reports the deepest record of microplastic ingestion, indicating that anthropogenic debris is bioavailable to organisms at some of the deepest locations in the Earth's oceans.

The fate of microplastic in marine sedimentary environments: A review and synthesis.
TL;DR: Quantitative assessments are needed of MP flux rates (g m-2 year-1) in a range of sedimentary environments and Fibres are the dominant MP type and account for 90% of MP on beaches and 49% of particles in tide-dominated estuaries.

TL;DR: The carbonyl index demonstrated that most of the floating microplastic was only slightly degraded, which highlights the need to raise environmental awareness through citizen science education and adopting good environmental practices.

TL;DR: In this paper, the authors quantified microplastic pollution in deep-sea sediments from the Great Australian Bight using an adapted density separation and dye fluorescence technique and estimated that 14 million tonnes of micro-plastic reside on the ocean floor.

TL;DR: It is shown that microplastic contaminates the shorelines at 18 sites worldwide representing six continents from the poles to the equator, with more material in densely populated areas, but no clear relationship between the abundance of miocroplastics and the mean size-distribution of natural particulates.

TL;DR: Model calculations and experimental observations consistently show that polyethylene accumulates more organic contaminants than other plastics such as polypropylene and polyvinyl chloride, and PCBs could transfer from contaminated plastics to streaked shearwater chicks.
