“…It indicated that BAP in the suspended particles had an important contribution to algal growth. It was similar with the results that BAP concentrations in the particles were well related to the contents of reactive, non-apatite inorganic phosphorus fractions [15] .…”

The investigation and continuous monitoring with an innovative iron oxide embedded cellulose acetate membrane (FeO/CAM) on the concentrations of biologically available phosphorus (BAP) were conducted in the Meiliang Bay of the Taihu Lake during summer in 2004. The results showed that the concentrations of dissolved (FeO-DP), particulate (FeO-PP) and total bioavailable phosphorus (FeO-P) had similar horizontal distribution. The BAP concentrations were the highest in those estuaries in the northern bay. With the decrease of the distance to the estuary or long shore, there was little difference between BAP concentrations in an open lake area. During the observation period, algal blooms occurred in most waters of the northern bay, which was reflected from the high concentrations of chlorophyll a (Chl-a). While they were not highest in the estuarine waters of those major rivers, this is the case for the BAP concentrations. The concentrations of Chl-a had a significantly positive correlation with those of bioavailable phosphorus in the open area of the Meiliang Bay. With the sediment resuspension induced by wind and wave, BAP concentrations increased in a short-term, indicating that the riverine P inputs mainly contribute to the concentrations of BAP in the estuarine water while internal P release was the major source of BAP in the open lake area. In the eutrophic shallow lake, the blooms of alga may cause pH increase and further result in internal P release. The above results showed that the new membrane of FeO/CAM can be used to monitor the concentrations of BAP and provide the scientific justifications for the control strategy of the lake eutrophication.

“…In fluvial systems, sediment bound P is transported by a resuspensiondeposition process (Verhoff et al, 1982) and the concentration of sediment P is generally less variable than that of ambient water (De Pinto et al, 1981). Because of the large sediment mass required for the present study, a sampling strategy was designed to maximize sampling density of river bed sediment during low flow conditions in late spring and summer while limiting the sampling frequency.…”

A sensitivity analysis was performed on a sediment-phosphate transport model by determining the phosphate sorption characteristics of separated size fractions and prepared size distributions of fine-grained ( < 64 jum) river sediment typically transported in two southern Ontario streams. The Langmuir equation was used to quantify phosphate release from the sediment. Results of the study indicated that Langmuir coefficients determined separately for individual grain size fractions can be used to model sediment-phosphate interactions. Under laboratory conditions, output from the model provided conservative estimates of phosphate release/uptake from grain size distributions of sediment in fluvial systems. The study provides phosphate release data for use in models that estimate sediment-P losses from watersheds.Effets de la distribution granulométrique sur ['adsorption des phosphates par les sédiments fluviaux: implications pour la modélisation du transport particulaire des phosphates Résumé Une analyse de sensibilité d'un modèle de transport particulaire des phosphates a été réalisée en déterminant les caractéristiques de 1'adsorption des phosphates sur différentes fractions granulométriques ainsi que sur diverses combinaisons d'entr'elles, préparées à partir de sédiments fins (<63 fivd) caractéristiques du transport solide de deux cours d'eau du sud de l'Ontario. L'équation de Langmuir a été employée pour quantifier la libération de phosphates du sédiment. Les résultats de l'étude indiquent que les coefficients de Langmuir déterminés pour différentes fractions granulométriques peuvent être employés pour modéliser les interactions du sédiment et des phosphates. Au laboratoire, les sorties du modèle fournissent une évaluation relativement satisfaisante des échanges de phosphates pour les distributions granulométriques rencontrées dans les systèmes fluviaux. L'étude fournit des données concernant l'émission de phosphates qui sont utilisables dans des modèles destinés à évaluer les exportations particulaires de phosphates en provenance de bassins versants.Open for discussion until I August 1995 68 M.

“…Jaisi et al (2010) have shown that P i adsorbed to mineral surfaces are constantly exchanged with P i in the surrounding water such that fractionation associated with adsorption/desorption is negligible over a matter of hours. Since NAIP particles near the Grand River are small (4-7 µm; Chomicki et al, 2016) and likely to stay in suspension for several days (DePinto et al, 1981), we would expect P i retained on NAIP particles that eventually settles within mussel beds to be equilibrated with δ 18 O P in the water column. If P i is released via redox mediated dissolution, we infer that such P i would retain δ 18 O P closer to that of lake water, and would be unlikely to explain the higher δ 18 O P values observed near the lake bed.…”

Blooms of filamentous benthic algae that plagued Lake Erie in the 1950s through 1970s were largely reduced through reductions of phosphorus (P) loading from point sources.Since the mid-1990s, these blooms have returned despite a period of relatively stable external P inputs. While increased loadings of dissolved P have been causally linked to cyanobacterial blooms in some parts of the lake, the impacts of ecosystem changes such as the effect of invasive species on nutrient cycling and availability have not been fully elucidated, leading to uncertainty as to the effectiveness of additional non-point P management actions. Here we use the oxygen isotope ratios (δ 18 O P ) of phosphate in concert with measures of water quality along the northern shore of the east basin of Lake Erie to identify sources and pathways of P cycling and infer potential importance in relation to annual blooms of Cladophora that foul the shorelines of eastern Lake Erie. δ 18 O P data indicate that potential external source signatures are rapidly overprinted by biological cycling of P by the plankton community and that much of the available phosphate in the nearshore waters is derived from hydrolysis of dissolved organic P compounds. Near the dreissenid-colonized lake bed, δ 18 O P was persistently and significantly enriched in 18 O relative to δ 18 O P measured in surface waters and was similar to δ 18 O P of phosphate excreted by dreissenid mussels in incubations. These results implicate dreissenid mussels as key agents in nearshore P cycling and highlight the importance of considering ecosystem changes in the development of nutrient management strategies designed to ameliorate symptoms of eutrophication.
