Perfluorinated compounds (PFCs) were found in fish muscle collected from high mountain lakes in the Qinghai-Tibetan Plateau, the highest and biggest plateau on Earth. In 96% of the total fifty-nine fish samples were found detectable perfluorooctane sulfonate (PFOS) as prominent PFCs, while only three for perfluorooctanoate (PFOA). The mean PFOS concentrations in fish muscle ranged 0.21ng/g-5.20ng/g based on dry weight, with the maximum in the Palgon Lake (1.30ng/g-7.54ng/g, dw) and the minimum in the Ni-yang River (<0.15ng/g-0.32ng/g, dw) among the seven sampling sites. Long-chain perfluorocarboxylic acids (C10, C11) were also identified in several locations. No significant correlations were observed between PFCs concentrations and sampling altitude or ages (fish). Results of the present work have demonstrated the existence of low level but detectable PFCs pollution in the Qinghai-Tibetan Plateau in China.
在青藏高原的高山湖泊中采集的鱼类肌肉中发现了全氟化合物（PFCs）。青藏高原是地球上最高、最大的高原。在总共 59 个鱼类样本中，有 96%检测到了显著的全氟辛烷磺酸（PFOS）作为主要的 PFCs，而只有 3 个样本检测到了全氟辛酸（PFOA）。根据干重，鱼类肌肉中的 PFOS 浓度范围为 0.21ng/g-5.20ng/g，其中帕贡湖（1.30ng/g-7.54ng/g，dw）的浓度最高，尼玛江（<0.15ng/g-0.32ng/g，dw）的浓度最低。在几个地点还鉴定出了长链全氟羧酸（C10、C11）。PFCs 浓度与采样海拔或鱼龄之间未观察到显著相关性。本研究结果表明，中国青藏高原存在低水平但可检测到的 PFCs 污染。
