We investigated the distribution of 17 individual per- and polyfluoroalkyl substances (PFASs) in 42 surface water samples collected from the East and South China Seas (7.0-36.0°N, 110.0°N-123.0°E). Concentrations of 7 individual PFASs, including perfluorobutane sulfonate (PFBS), perfluorohexane sulfonate (PFHxS), perfluoropentanoic acid (PFPA), perfluorohexanoate (PFHxA), perfluoroheptanoate (PFHpA), perfluorooctanoic acid (PFOA), and perfluorooctane sulfonamide (FOSA), were quantified in the East China Sea, but only concentrations of PFOA and FOSA were quantified in the South China Sea. The total concentrations of the 17 PFASs ranged from 181 to 2658pg/L in the East China Sea and from 62 to 494pg/L in the South China Sea. We also show that river fluxes and ocean currents had a strong influence on the distribution of PFASs in the East China Sea. Using ArcGIS 10.1, we show how ocean currents control the spatial distribution of PFOA in the central South China Sea.
我们调查了来自东海和南海（7.0-36.0°N，110.0°N-123.0°E）的 42 个地表水样本中 17 种个体全氟和多氟烷基物质（PFASs）的分布。在东海，我们定量检测了 7 种个体 PFASs，包括全氟丁烷磺酸（PFBS）、全氟己烷磺酸（PFHxS）、全氟戊酸（PFPA）、全氟己酸（PFHxA）、全氟庚酸（PFHpA）、全氟辛酸（PFOA）和全氟辛烷磺酰胺（FOSA），但在南海只定量检测了 PFOA 和 FOSA。在东海，17 种 PFASs 的总浓度范围为 181-2658pg/L，在南海的总浓度范围为 62-494pg/L。我们还表明，河流通量和洋流对东海 PFASs 的分布有很强的影响。使用 ArcGIS 10.1，我们展示了洋流如何控制南海中部 PFOA 的空间分布。
