Seawater samples from 50 sites in the BS and YS were collected to investigate the spatial distribution of 7 OPs. Concentrations of the total OPs (ƩOPs) in the BS and YS ranged from 8.12ngL to 98.04ngL with a geometric mean (GM) of 23.70ngL. Tris(1-chloro-2-propyl) phosphate (TCPP) was the dominant compound, followed by tris(2-chloroethyl) phosphate (TCEP) and triphenylphosphine oxide (TPPO). The ƩOPs together with the most commonly detected individual OPs (TCPP, TCEP, tris(1,3-dichloro-2-propyl) phosphate (TDCPP), tri-iso-butyl phosphate (TiBP), triphenyl phosphate (TPhP), and TPPO) tended to decrease from nearshore to offshore and from the surface to the bottom seawaters, indicating major land-based sources. Furthermore, the Yellow Sea Cold Water Mass (YSCWM), Changjiang Diluted Water (CDW), Taiwan Warm Current (TaWC), and Subei Coastal Water (SCW) influenced the horizontal and vertical distributions of the OPs in the study area.
采集了渤海和黄海50个站点的海水样本，以研究7种有机磷的空间分布。渤海和黄海中总有机磷（ƩOPs）的浓度范围为8.12纳克/升至98.04纳克/升，几何平均值（GM）为23.70纳克/升。磷酸三（1-氯-2-丙基）酯（TCPP）是主要化合物，其次是磷酸三（2-氯乙基）酯（TCEP）和三苯基氧化膦（TPPO）。ƩOPs以及最常检测到的个别有机磷（TCPP、TCEP、磷酸三（1,3-二氯-2-丙基）酯（TDCPP）、磷酸三异丁酯（TiBP）、磷酸三苯酯（TPhP）和TPPO）从近岸到近海以及从表层海水到底层海水均呈下降趋势，表明主要来源为陆地。此外，黄海冷水团（YSCWM）、长江冲淡水（CDW）、台湾暖流（TaWC）和苏北沿岸水（SCW）影响了研究区域内有机磷的水平和垂直分布。
