Researchers documented the first record of microplastic ingestion in cold-seep organisms at 1,155 m depth in the South China Sea, finding ingestion rates above 80% in both Gigantidas platifrons mussels and Shinkaia crosnieri squat lobsters, with polyethylene fibers in the 500-1000 micrometer range predominating.
The deep sea is considered the final sink for microplastics (MPs) pollution in marine environments. Despite MPs being consumed by many organisms, their presence in cold-seep organisms remains unclear. At cold seep site F in the South China Sea, which lies 1155 m deep, MPs were investigated in Gigantidas platifrons and Shinkaia crosnieri, both ecologically important species. Microplastics ingestion rates were 80.98 % and 81.25 % in G. platifrons and S. crosnieri, respectively. The average MPs abundance for G. platifrons and S. crosnieri was 2.80 ± 0.69 MPs/ind (2.20 ± 2.75 MPs/g) and 2.30 ± 0.27 MPs/ind (4.74 ± 3.08 MPs/g), with no significant difference between species. There were predominantly fibrous MPs ingested by cold-seep organisms, sized 500-1000 μm, blue in color, and polyethylene terephthalate and cellophane in composition. The results confirm the presence of MPs in cold-seep organisms in the South China Sea, providing further evidence that MP pollution exists in the deep sea.
