Recent studies have highlighted the prevalence of microplastic (MP) pollution in global marine environment and these pollutants been found to contaminate even remote regions, including Southern Ocean south polar front. Previous this region mostly focused on MPs larger than 300 μm, potentially underestimating extent MP pollution. This study is first investigate surface waters front, with a focus small 500-11 μm size. Seventeen water samples were collected southern Weddell Sea using an in-house-designed sampling system. The analysis entire sample micro-Fourier transform infrared spectroscopy (μFTIR) focal plane array (FPA) detection revealed presence all samples, vast majority detected being smaller (98.3 %). mean concentration reached 43.5 (± 83.8) m

The Arctic and Antarctica represent two of the most inhospitable poorly investigated biomes in world. Although polar regions are still perceived as some pristine places existence, these remote no longer immune to anthropogenic pollution, particular, micro- nanoplastics.

The stomach content of 60 krill specimens from the Southern Ocean were analyzed for presence microplastic (MP), by testing different sample volumes, extraction approaches, and applying hyperspectral imaging Fourier-transform infrared spectroscopy (μFTIR). Strict quality control was applied on generated results. A high load residual materials in pooled samples hampered analysis avoided a reliable determination putative MP particles. Individual stomachs displayed results, however, only after re-treating with hydrogen peroxide. Before this treatment, lipid rich residues resulted false assignments polymer categories hence, particle numbers. Finally, identified 4 out 60, one per stomach.

Antarctica has traditionally been viewed as a relatively isolated ecosystem. Although still considered pristine, it is increasingly also being affected by microplastic pollution. Reported high sea floor concentrations raise concern that these ecosystems might act major sink for This significant species in those remote are likely more sensitive to rapid environmental change due level of specialization, and lower tolerance levels. Microplastic ingestion fish barely assessed latitude environments. Here we aimed provide baseline data the eastern Weddell Sea, which particularly remote, suggested an area conservation.
