Due to wide use of perfluoroalkyl substances (PFASs) (e.g., in metal-plating, in fire-fighting foam, lubricants) and their resistance to degradation, they occur widely in the environment. The aim of this study was to estimate the environmental risk resulting from the presence of PFASs in the Gulf of Gdansk. Therefore, 17 PFASs concentrations were determined using ultra performance liquid chromatography with tandem mass spectrometry detection (UPLC-MS/MS). Additionally, sediment ecotoxicity was investigated. The results of the chemical analysis were used to asses environmental risk of PFASs. In samples collected around discharge collectors from a wastewater treatment plant and the Vistula mouth, Σ17PFASs values were 0.00403 ÷ 40.6 and 0.509 ÷ 614 ng/g d.w., respectively. In samples collected around discharge collectors, PFHxA, PFPeA, PFHpA, and PFOA were dominating, while at the Vistula River mouth, PFHxS, PFDS, and PFBS were prevalent. For most sediments, no toxic effect was observed in the toxicity tests with and . There was no observed correlation between the PFASs level and their ecotoxicity. Generally, the results of environmental risk assessment indicate that the PFASs would not generate high impact on the aquatic life (five water samples have shown medium risk related to PFBS and PFDoA).
由于全氟烷基物质 (PFASs)（例如，在金属电镀、消防泡沫、润滑剂中的应用）的广泛使用及其抗降解性，它们广泛存在于环境中。本研究旨在评估加里宁格勒湾 PFASs 存在所带来的环境风险。因此，使用超高效液相色谱-串联质谱检测法 (UPLC-MS/MS) 测定了 17 种 PFASs 的浓度。此外，还研究了沉积物的生态毒性。化学分析结果用于评估 PFASs 的环境风险。在污水处理厂排放收集器周围和维斯图拉河口采集的样本中，Σ17PFASs 值分别为 0.00403 ÷ 40.6 和 0.509 ÷ 614 ng/g d.w.。在排放收集器周围采集的样本中，PFHxA、PFPeA、PFHpA 和 PFOA 占主导地位，而在维斯图拉河口，PFHxS、PFDS 和 PFBS 则较为常见。在毒性测试中，大多数沉积物均未观察到毒性效应。PFASs 水平与生态毒性之间没有观察到相关性。总体而言，环境风险评估结果表明，PFASs 不会对水生生物产生高影响（五个水样显示与 PFBS 和 PFDoA 相关的中等风险）。
