Microplastics in Arctic deep-sea sediments from the HAUSGARTEN observatory@en

Although mounting evidence suggests the ubiquity of microplastic in aquatic ecosystems worldwide, our knowledge of its distribution in remote environments such as Polar Regions and the deep sea is scarce. Here, we analyzed nine sediment samples taken at the HAUSGARTEN observatory in the Arctic at 2,340 - 5,570 m depth. Density separation by MicroPlastic Sediment Separator and treatment with Fenton's reagent enabled analysis via Attenuated Total Reflection FTIR and µFTIR spectroscopy. […]尽管日益增多的证据表明，微塑料（microplastic）在全球水生生态系统中无处不在，但我们对其在极地地区、深海等偏远环境中的分布认知仍较为匮乏。本研究对取自北极HAUSGARTEN观测站、水深2340至5570米的9份沉积物样品展开了分析。通过微塑料沉积物分离器（MicroPlastic Sediment Separator）完成密度分离，并经芬顿试剂（Fenton's reagent）处理后，可借助衰减全反射傅里叶变换红外光谱（Attenuated Total Reflection FTIR）与显微傅里叶变换红外光谱（µFTIR）完成样品检测分析。[...]
