This study provides the first evidence of the sources and loads of perfluorochemicals (PFCs) to the NW Mediterranean Sea. Five PFCs were analyzed in 45 seawater samples collected along the Catalan coast. Total PFCs ranged from 0.07 to 13.0 ng/l, being the levels higher in ports than in coastal waters. To determine the sources of PFCs, 8 wastewater treatment plants (WWTPs) effluents and 6 rivers discharging to the sea were also analyzed. WWTP effluents contained total PFCs levels ranging from 3.47 to 132 ng/l but due to the relatively low discharge flows, they contributed to 34.7 g/d to the sea. Total PFCs in rivers ranged from 2.24 to 21.9 ng/l and were the principal PFCs contributors to the sea. Overall, a total load of 190 g/d of PFCs are discharged to the NW Mediterranean coast. The effects and risk of PFCs discharges to the Mediterranean basin are discussed.
本研究首次提供了西北地中海海水中全氟化学品(PFCs)的来源和负荷的证据。在加泰罗尼亚沿海采集的 45 个海水样本中分析了 5 种 PFCs。总 PFCs 的范围为 0.07 至 13.0ng/L,在港口的水平高于沿海水域。为了确定 PFCs 的来源,还分析了 8 个污水处理厂(WWTP)的废水和 6 条入海河流。WWTP 废水中总 PFCs 的含量范围为 3.47 至 132ng/L,但由于排放量相对较低,它们对海洋的贡献为 34.7g/d。河流中的总 PFCs 含量范围为 2.24 至 21.9ng/L,是海洋中 PFCs 的主要贡献者。总的来说,有 190g/d 的 PFCs 被排放到西北地中海沿海。讨论了 PFCs 排放对地中海盆地的影响和风险。
