Different phosphorus fractions, including total dissolved P (TDP), dissolved inorganic P (DIP), total particulate P (TPP), and particulate inorganic P (PIP), were analyzed in the Danshuei River Estuary (DRE), northern Taiwan to study the P partitioning within the estuary. Relatively higher concentrations of TDP (4.3-12.4 μM) and TPP (2.3-8.7 μM) were generally found in the upper estuary, salinity <5 region, during the four surveys. The DIP concentration generally dominated the total P pool (TDP + TPP) within the estuary. However, dissolved organic P (DOP) became the important fraction in the salinity >25 region, probably attributed to phytoplankton production because the higher DOP concentration was generally accompanied with a higher Chl. a concentration. The TPP concentrations generally correlated well with the total particulate Fe and Mn concentrations, suggesting that particulate Fe and Mn played crucial roles influencing the P distribution within the DRE.
在台湾北部的淡水河口（DRE）分析了不同的磷组分，包括总溶解磷（TDP）、溶解无机磷（DIP）、总颗粒磷（TPP）和颗粒无机磷（PIP），以研究河口内的磷分配。在四次调查中，上河口、盐度<5 的区域通常发现较高浓度的 TDP（4.3-12.4 μM）和 TPP（2.3-8.7 μM）。在河口内，DIP 浓度通常占总磷库（TDP+TPP）的主导地位。然而，在盐度>25 的区域，溶解有机磷（DOP）成为重要的组分，这可能归因于浮游植物的生产，因为较高的 DOP 浓度通常伴随着较高的叶绿素 a 浓度。TPP 浓度通常与总颗粒铁和锰浓度密切相关，表明颗粒铁和锰在影响 DRE 内磷分布方面发挥了关键作用。
