“…e results showed the following: TP from 416.5 to 638.5 mg/kg in the East China Sea sediment cores [25]; TP from 465 to 663.4 mg/kg in the Changjiang Estuary and adjacent East China Sea surface sediments [12]; TP from 474 to 1,035 mg/kg in the northern Gulf of Mexico sediment cores [13]; TP from 409.2 to 3,689 mg/kg in the central Pacific Ocean surface sediments [14]; TP of 466.24-669.29 mg/kg in the Sishili Bay, China [15], TP from 246.76 to 692.54 mg/kg at the eastern coast of Hainan Island surface sediment [17]; TP from 369.83 to 739.97 mg/kg in the East China Sea core sediments [26]; TP from 431 to 594 mg/ kg in the Caspian Sea surface sediments [18]. Similarly, in our study areas, the surface sedimentary TPs were lower compared to the sedimentary TPs in other locations elucidated using the SMT method: TP ranging from 520.8 to 1376.4 mg/kg in the Loire Estuary; from 130.2 to 787.4 mg/ kg in the Gironde Estuary; from 189.1 to 576.6 mg/kg in the Bay of Seine [19]; at 412.61 mg/kg in the Gulf of Gdańnsk [20]; from 217.8 to 1,640 mg/kg in the lakes in the mid and lower Changjiang River [27]; from 303.87 to 761.59 mg/kg in the subtropical wetland reserve in southeast China [21]; 87.28-2610.43 mg/kg in the main rivers discharging into the Bohai Sea [22]. us, the sedimentary TP found in our study areas indicates that these locations were less polluted compared to most other areas.…”

“…Some studies used the SMT method to elucidate the sedimentary P species in various environments. Studies of sedimentary P forms in the Bay of Seine and the Loire and Gironde Estuaries [19] and the Gulf of Gdańnsk [20] found that the Fe/Al-P fraction and TP concentrations were mainly due to fine particles. e Loire and Gironde Estuaries, which frequently showed hypoxia, had lower Fe/Al-P fractions than the Bay of Seine did [19].…”

Sedimentary phosphorus (P) forms are important representatives of P sources and their bioavailability as well as the potential of sediments to release P in water. In this study, surface sediments along a transect of the Changjiang Estuary and two transects along the Andong salt marsh in the southwest of Hangzhou Bay were subjected to the elucidation of sedimentary P species using the standards, measurements, and testing (SMT) and sequential extraction (SEDEX) methods. The results showed that the mean sedimentary P forms elucidated by the SMT method were as follows: organic P (OP; ∼11–14 mg/kg; ∼30–45% of total P; TP) > apatite P (∼5–15 mg/kg; ∼21–36% TP) > Fe/Al-P (∼8–14 mg/kg; ∼31–34% TP), with inorganic P (IP) composing 54–70% of TP. The mean sedimentary P forms elucidated by the SEDEX method were as follows: authigenic P (∼54–68 mg/kg; ∼41–46% TP) > extractable P (Ex-P; ∼36–53 mg/kg; ∼28–34%) > Fe-P (∼21–27 mg/kg; ∼13–19%) > OP (∼8.7–13 mg/kg; ∼5–8%) > detrital P (De-P; ∼2 mg/kg; ∼1–2% TP), with IP composed of ∼91–94% TP. These results showed that the SEDEX method elucidated higher concentrations of sedimentary P forms as well as the TP from these coastal sediments although the SMT method had the advantage of being more economic and faster. The results of both the SMT and SEDEX methods showed that the Andong salt marsh and Changjiang Estuary sediments had much bioavailable P. The mean percentages of bioavailable P from the SMT and SEDEX methods were ∼64–74% and 52–56% of TP, respectively, indicating that these sediments were prone to release P to the coastal areas.

“…In Zhushan Bay, PC1, PC2 and PC3 explained 40.9%, 24.8% and 17.5% of all the variables, respectively (Table 5). In general, PC1 always includes the decisive factors in data (Łukawska-Matuszewska et al 2014). In this study, the TP, Fe/Al-P, Ca-P, OP and sediment WC and OM concentration had substantial loadings on the PC1 axis, reflecting the dominant position of phosphorus and sediment quality of Zhushan Bay.…”

Effects of algae and hydrophytes on the inorganic phosphorus pool of shallow hypereutrophic Lake Taihu

Sedimentary phosphorus is a crucially potential source of phosphorus in the eutrophic lake ecosystem. Different ecological types are supposed to affect the presence and variation of sediment phosphorus. On the basis of field investigations, the total sediment phosphorus load in Zhushan Bay was 1,457.48 mg/kg, nearly four times that of the hydrophyte-dominated area. Thereinto, 41.1% was in the form of iron and aluminum-bound phosphorus, which explicitly indicated the phosphorus contamination there. Analytical methods such as Pearson correlation, contamination assessment and principle component analysis were conducted to find out that ‘contamination’ was not equivalent to ‘release risk’. The contamination classification of East Lake Taihu was ‘clean’ in general. However, 63.3% of the total phosphorus could be mobilized under certain conditions. Therefore, light phosphorus loading does not equal to less release risk. In the long run, the implicit phosphorus release by the activation of organic phosphorus in hydrophytic areas needs close attention. This study provides a reference to understand the influence of hydrophytes and algae on the phosphorus cycle of sediment.

“…Other external sources of P could be from groundwater, fluvial, and atmosphere [27]. Eutrophication can cause high OM input to sediments, which results in increased sedimentary TC, OC, TN, TP, and OP levels [28], followed by increased decomposition of OM [29]. This sequence of events occurred in the downstream Kapuas River, where the sediment also showed high labile, refractory, and total OM and high OP, IP, and TP (Figures 2 and 3).…”

This study assessed the sedimentary organic matter (OM) and phosphate along the world’s longest river on an island: the Kapuas River in West Kalimantan, Indonesia. The surface sediment was tested using the loss-on-ignition experiment to determine the % labile OM, % refractory OM, and % total OM and the Rp values (the ratio of refractory to total OM). The C/N ratios and the inorganic phosphate (IP), organic phosphate (OP), and total phosphate (TP) levels were also determined. The combination of high Rp values and low C/N ratios along the upper river indicated the possible presence of relatively degraded material; the low Rp values and high C/N ratios downstream were indicative of a fresher terrestrial signal. Sedimentary P levels were the highest along the densely populated areas downstream from the Kapuas River; the second highest along the midstream river, which is surrounded by oil palm plantations; and the lowest along the upper river, which is surrounded by forest. Higher levels of OM, IP, OP, and TP downstream along the Kapuas River indicated the presence of anthropogenic sources of OM and P.
