“…Fe/Al–P had a large spatial variation, with higher concentrations at NW corner and the western tip where external pollution from the discharge of wastewater is serious. Some researchers reported that Fe/Al–P concentration in sediments was closely related to the pollution degree , which was also confirmed in this study.…”

“…The potential release risk of sediment P in Swan Lake P fractions in sediments can be used to evaluate P bioavailability and release risk for the overlying water at a certain degree [9,10,12]. In Swan Lake, different bioavailable P followed the order: AAP > Olsen-P > WSP > RDP, which was in agreement with the results in other water bodies in China [10,27]. Higher concentrations of WSP, RDP, and Olsen-P were found at the western tip, the SE corner and central area, suggesting that the sediments at these areas had higher P availability for algal growth at present.…”

“…AAP is potentially available for algal uptake; while WSP and RDP are immediately available P for algae, and easily to release from the sediments particularly when water P concentration is depleted. For the heavily polluted sediments, BAP showed close relationships with IP and Fe/Al–P in Yangtze River . In different aquatic ecosystems, the trophic status and bioavailability of sediment P have marked differences due to external inputs, sediment properties, P forms, and so on.…”

Rongcheng Swan Lake, a natural coastal wetland, is connected to Rongcheng Bay of Yellow Sea, China. In this lagoon, water quality has deteriorated gradually in recent 30 years and filamentous Chaetomorpha linum have bloomed during the past five years. In present study, the concentration, fractions, and bioavailability of phosphorus (P) in surface sediments were investigated throughout the lake. In order to evaluate P retention ability of the wetland, six sediment samples from different lake regions were collected to study P adsortion kinetics, adsortion capacity and the relation to sediment properties. In Swan Lake, total P concentrations in sediments varied from 79 to 616 mg/kg, which were significantly higher in northwest region than those in southeast region. Sediment grain size and external inputs were the main factors affecting P distribution. Inorganic P concentration was obviously higher than that of organic P, and Ca-P was the important form in the sediments. Fe/Al-P showed a large spatial variation, with relatively high concentrations occurring at the northeastern corner and the western tip strongly affected by the discharge of wastewater. The adsorption isotherms were well fitted by Linear equation at low P conditions and by Langmuir equation at high initial P concentrations, respectively. The sediments in the northern and central lake had higher P adsorption capacity, while in southern lake the degree of P saturation of the sediments was high. Ammonium oxalate extractable Al, organic matter, and fine particle were important factors influencing P adsorption. In Swan Lake, algae available P (AAP) was the largest form of bioavailable P, followed by Olsen-P; moreover, AAP and Olsen-P showed significant correlations with Fe/Al-P. As a whole, TP concentration in sediments from Swan Lake was low, and the sediments at most regions had buffering ability for P in overlying water; while at the western tip of lake where macroalgal blooms frequently breakout, AAP concentration was relatively high and the sediments had higher potential for releasing P into water column.

“…Others have reported that the bio-available P extracted from TP mainly correlates with NaOH-P in heavily polluted sediments [41]. Therefore, NaOH-P has been used to estimate both short-and long-term availability of P, which is released for the growth of phytoplankton when anoxic conditions prevail at the water-sediment interface [9,42].…”

“…Zhou et al (2001) used linear correlation models to characterize the relationship between TP and the four fractions of BAP. Wang et al (2010) found in heavily polluted sediments, that BAP has a significant relationship with TP, NaOH-P and IP. However, this study represents a rare attempt to consider all influence P fractions together into one feasible model and predict BAP fractions and their origin source.…”

Bioavailable phosphorus (BAP) plays an important role in phosphorus (P) release from lake and river sediments, as well as serves as an indicator for the potential P-release risk in sediment. Developing a feasible model which could predict BAP via other P fractions is needed for the lakes and reservoirs without regular BAP monitoring. The algal available P (AAP), NaHCO 3 extractable P (Olsen-P), water soluble P (WSP) and readily desorption P (RDP) are four fractions of BAP. The vertical and spatial distributions of BAP fractions of three sediment cores from Jiulongkou Lake were analyzed. In addition, the P fractions, including total P (TP), organic P (OP), inorganic P (IP), non-apatite inorganic P (NAIP), and apatite P (AP) were measured to develop a model for predicting BAP. The model for each BAP fraction was developed based on datasets from Jiulongkou Lake and validated by the datasets collected from Wujin and Wugong Lake. The results showed that all of the four BAP fractions decreased with depth, along the direction of contaminant transport. Their rank order was AAP [ Olsen-P [ WSP [ RDP in all samples. The concentration of BAP was affected by the anthropogenic input and aquatic macrophyte growth. Each of the four BAP fractions could be simulated by different P fractions: both AAP and Olsen-P were expressed by NAIP and OP, WSP had a significant relationship with OP, and RDP had significant relationship with IP. NAIP and OP were the major sources of the BAP fraction. The simulated results in two other lakes further illustrated that this model could be used to successfully predict the BAP concentrations in lakes in the study area, and holds promise for predicting the BAP levels in other lakes and reservoirs as well.
