“…CFAP represents an oceanic sink for reactive P whereas FAP does not (Liu et al, 2004b). In this study, we employed the SEDEX method originally developed by Ruttenberg (1992) and modified by adding an aluminum-bound P extracting step to determine different phosphorus phases (Gunduz et al, 2011). The six operationally defined forms of reactive phosphorus phases which were separated under this scheme are: (i) exchangeable or loosely sorbed phosphorus (Ads-P); (ii) aluminum-bound phosphorus (Al-P); (iii) iron-bound phosphorus (Fe-P); (iv) authigenic apatite plus CaCO 3 -bound phosphorus plus biogenic apatite (Ca-P); (v) detrital apatite plus other inorganic phosphorus (De-P) and (vi) organic phosphorus (OP).…”

“…Analyses of P concentration were performed with an Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES) (Optima 7000DV, PerkinElmer, USA) and the analytical conditions followed Gunduz' study (Gunduz et al, 2011). The selection of instrumental parameters and optical wavelength was based on obtaining good sensitivity, reasonable detection limits, and eliminating interferences (Aydin et al, 2009).…”

“…The selection of instrumental parameters and optical wavelength was based on obtaining good sensitivity, reasonable detection limits, and eliminating interferences (Aydin et al, 2009). In this study, 213.617 nm was chosen as spectral wavelength for P analyses (Gunduz et al, 2011).The analytical data quality was guaranteed through the implementation of laboratory quality assurance and quality control methods, including the use of standard operating procedures, calibration with standards, analysis of reagent blanks, and analysis of replicates. The precision of the analytical procedures was expressed as the relative standard deviation (RSD).…”

a b s t r a c tPhosphorus (P) in surface sediments of the Laizhou Bay (LB) and the coastal waters around the Zhangzi Island (ZI) was analyzed. Six forms of P were separated -exchangeable or loosely sorbed P (Ads-P), aluminum-bound P (Al-P), iron-bound P (Fe-P), authigenic apatite plus CaCO 3 -bound P plus biogenic apatite (Ca-P), detrital apatite plus other inorganic P (De-P) and organic P (OP). The average contents of P in the LB were in the order: De-P > OP > Ca-P > Fe-P > Ads-P > Al-P; in the ZI, the corresponding order was De-P > OP > Fe-P > Ca-P > Ads-P > Al-P. Due to the high nutrient loadings from the surrounding rivers, TP contents in sediments of the LB were higher than in those of the ZI. The potential bio-available P (Ads-P and OP) accounted for 14.7% and 24.2% of TP in sediments of the LB and the ZI, respectively.Ó 2014 Elsevier Ltd. All rights reserved.As an important biogenic element in the ocean, phosphorus (P) directly affects the primary productivity of the ocean and has a significant impact on the marine carbon cycle (Lui and Chen, 2011;Yu et al., 2012); P is also directly related to the global climate and environmental changes (Krom et al., 2004). Hecky and Kilham (1988) pointed out that P might be the element which controlled the global marine biological productivity during a long geologic time scale (>1000 years). As an important reservoir of P in marine environment, sediment not only has a buffering effect on the P content in the overlying water, but also is an important source of P in seawater (Giblin et al., 1997;Zabel et al., 1998). Fisher et al. (1982) reported that sediments provided 28-35% of P needed in the primary productivity of coastal marine ecosystems.Both organic and inorganic forms of P are present in marine sediments. Inorganic forms of P may be adsorbed onto the surfaces of minerals, or be bound to aluminum, iron, or calcium (Föllmi, 1996;Benitez-Nelson, 2000;Łukawska-Matuszewska and Bolałek, 2008;Song, 2010). The binding forms of P in sediments have major influences on transportation, degradation, and the ultimate fate of P in marine ecosystems. Only certain forms of P can be transformed into bio-available ones after being affected by physical, chemical and biological factors, including desorption, dissolution and reduction processes (Song, 2010). After that, the bio-available forms of P are released into the overlying water. These certain forms of P become important factors affecting the trophic status of water or causing eutrophication (Eijsink et al., 2000). Therefore, research on the geochemical forms of P in sediments may help researchers understand the dynamic cycle of P in seawater and sediments, such as migration and transformation between sediments and the overlying water, and subsequent diagenesis and other geochemical processes (Zabel et al., 1998;Eijsink et al., 2000).The Laizhou Bay and the surrounding marine area of the Zhangzi Island (hereafter referred to as the Zhangzi Island for short) are important mariculture zones in China, and they are located in the B...

“…Surveys show that the content of sediment phosphorus differs greatly in different zones. For instance, the concentration of total phosphorus in sediments is between 152.18 mg/kg and 275.12 mg/kg in the Antalya Lake of Turkey, and the contamination risk is low [38]. The concentration of sediment phosphorus ranges from 443 mg/kg to 611 mg/kg in Baiyangdian Lake, which has become a potential factor of water eutrophication [16].…”

Sediment gradually accumulates at the bottom of reservoirs after decades of running. To explore the influences of sediments on the water quality of reservoirs, the spatial distribution, adsorption/release characteristics, and environment influence of sediment pollutants should be analyzed. In this paper, the spatial distributions of phosphorus (P) and P fractions in the Biliuhe reservoir (river valley reservoirs) sediments were investigated. The adsorption and release characteristics of sediments P were studied in the experiment, while its environmental influence was analyzed too. The results indicate that the concentration of P in sediments was higher at the dam and the Zhongling site, while lower at other entrances of the reservoir and the smallest in the water-level fluctuating zone. Total Phosphorus (TP) varied from 355.46 to 764.57 mg/kg. Inorganic Phosphorus (IP) was the main form of TP in sediments, making up a proportion of 56-75%, while the correlation coefficient of P bound to Al, Fe, and Mn oxides was 0.922. Hydroxide (Fe/Al-P) was the main form of IP, which accounted for 46-83% with a correlation coefficient of 0.888. The maximum adsorption capacity calculated by Langmuir model was between 714.29 and 3333.33 mg/kg. The adsorption efficiency obtained by the Freundlich model was within the range of 0.40-1.42, which indicated that P adsorption was more difficult in the water-level fluctuating zone. The critical adsorption and release concentration range was 0.1-0.2 mg/L for the majority of the sampling points. The amount of P released in 24 h (the initial concentration of TP in the overlying water was 0 mg/L) accounted for 1.15-4.16% of TP in sediments, which was higher than the average concentration in the reservoir. It is concluded that the sediment is the potential pollution source. The relationship between the change of environmental factors and the release of sediment contaminants should be considered in the future.

Worldwide, many aquatic systems are under anthropogenic induced pressure by elevated nutrient inputs. In particular, increased nitrogen and phosphorus usage have led to human‐induced eutrophication (including cyanobacterial blooms and hypoxia) of all kinds of water bodies. Associated pressures need to be described, and diminished, in order to reach a sustainable human usage of ecosystems. The Baltic Sea is a model system, as it is prone to Global Change, and is strongly influenced by human actions and shows recurrent cyanobacterial blooms and hypoxia. There have already been several actions to ameliorate these problems, e.g. by reducing the inflow of phosphorus. However, even the strongest possible reductions are currently not enough to restore the Baltic Sea. Coastal water bodies are still highly eutrophic, and the catchment area is affected by permanent runoff‐events from adjacent land. Furthermore, new approaches are needed to improve the efficiency of water treatment plants. On the other side, legislation is sometimes inefficient on a local scale. Such problems can only be solved in multidisciplinary approaches that include environmental, engineering and social sciences. Here, we present an overview of recent research with emphasis on phosphorus and its flows and controls into the Baltic Sea from the German catchment area. image
