The platypus (Ornithorhynchus anatinus) is a semi-aquatic monotreme that occupies a high trophic position in the freshwater ecosystems of eastern mainland Australia and Tasmania. Platypuses are continuously exposed to anthropogenic contaminants including perfluorooctane sulfonate (PFOS). This study examined PFOS concentrations in the livers of deceased platypuses (eight wild; one captive) that were opportunistically collected across NSW over a two- and a half-year period. There was a large variation in PFOS concentrations, ranging from < 1 µg/kg to 1200 µg/kg. This study presents the first report of PFOS contamination in platypuses, revealing their PFOS levels are broadly similar to those found in river otters (Lutra canadensis) and lower than those in American mink (Mustela vison), both which occupy similar ecological niches in freshwater systems. This study raises concerns about the impact of PFOS on platypus health.
鸭嘴兽（Ornithorhynchus anatinus）是一种半水生单孔目动物，在澳大利亚东部大陆和塔斯马尼亚的淡水生态系统中占据着较高的营养位置。鸭嘴兽会持续接触到包括全氟辛烷磺酸（PFOS）在内的人为污染物。本研究检测了在新南威尔士州（NSW）范围内，通过偶然机会收集的 8 只野生鸭嘴兽和 1 只圈养鸭嘴兽肝脏中的 PFOS 浓度。这些鸭嘴兽肝脏中的 PFOS 浓度差异很大，范围从<1µg/kg 至 1200µg/kg。本研究首次报道了鸭嘴兽 PFOS 污染情况，表明它们的 PFOS 水平与在河流獭（Lutra canadensis）中发现的水平大致相似，低于在淡水系统中占据相似生态位的美洲水貂（Mustela vison）中的 PFOS 水平。本研究引起了人们对 PFOS 对鸭嘴兽健康影响的关注。
