研究了东海和南海（7.0-36.0°N，110.0°N-123.0°E）42个表层水样品中17种全氟烷基和多氟烷基物质（PFASs）的分布特征。对东海海域全氟丁烷磺酸盐（PFBS）、全氟己烷磺酸盐（PFHxS）、全氟戊酸（PFPA）、全氟己酸盐（PFHxA）、全氟庚酸盐（PFHpA）、全氟辛酸（PFOA）和全氟辛烷磺酰胺（FOSA）等7种PFAS的浓度进行了定量分析，而对南海海域仅对PFOA和FOSA进行了定量分析。17种PFAS的总浓度在东海为181 - 2658 pg/L，在南海为62 - 494 pg/L。我们还表明，河流通量和洋流对PFASs在东海的分布有很大的影响。使用ArcGIS 10.1，我们展示了洋流如何控制PFOA在南海中部的空间分布。
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 2658 pg/L in the East China Sea and from 62 to 494 pg/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.
