The occurrence and temporal variation of 18 perfluoroalkyl substances (PFASs) and 8 polybrominated diphenyl ethers (PBDEs) in the European Alps was investigated in a 10 m shallow firn core from Colle Gnifetti in the Monte Rosa Massif (4455 m above sea level). The firn core encompasses the years 1997-2007. Firn core sections were analyzed by liquid chromatography-tandem mass spectrometry (PFASs) and gas chromatography-mass spectrometry (PBDEs). We detected 12 PFASs and 8 PBDEs in the firn samples. Perfluorobutanoic acid (PFBA; 0.3-1.8 ng L(-1)) and perfluorooctanoic acid (PFOA; 0.2-0.6 ng L(-1)) were the major PFASs while BDE 99 (<MQL-4.5 ng L(-1)) and BDE 47 (n.d.-2.6 ng L(-1)) were the major PBDEs. This study demonstrates the occurrence of PFASs and PBDEs in the European Alps and provides the first evidence that PFASs compositions may be changing to PFBA-dominated compositions.
本研究在欧洲阿尔卑斯山的罗莎山（Monte Rosa Massif）格利尼菲蒂（Colle Gnifetti）采集了 10 米深的雪芯，探讨了 1997-2007 年期间 18 种全氟烷基物质（PFASs）和 8 种多溴二苯醚（PBDEs）的存在和时间变化。雪芯样本通过液相色谱-串联质谱法（PFASs）和气相色谱-质谱法（PBDEs）进行分析。我们在雪芯样本中检测到 12 种 PFASs 和 8 种 PBDEs。全氟丁烷酸（PFBA；0.3-1.8ng/L）和全氟辛酸（PFOA；0.2-0.6ng/L）是主要的 PFASs，而 BDE 99（<MQL-4.5ng/L）和 BDE 47（未检出-2.6ng/L）是主要的 PBDEs。本研究证明了 PFASs 和 PBDEs 在欧洲阿尔卑斯山的存在，并首次提供了 PFASs 组成可能正在向以 PFBA 为主的组成转变的证据。
