“…Similar correlations between phosphorus release and NaOH extractable P have been noted by Messer et al (1984). Chemical remobilization is enhanced under conditions such as prevail in Esthwaite Water where summer algal blooms are frequently associated with large increases in pH to values greater than 10 (Tailing.…”

1. Vertical profiles of pH were measured at nine shallow water (<5m) locations in Esthwaite Water. These indicate strong gradients of pH near the sediment-water interface suggesting a marked buffering capacity of the sediments.2. Thirteen littoral sediment cores were horizontally sectioned and sequentially extracted (O.SMNaHCO^, O.lMNaOH, IMHCI) and analysed for soluble reactive phosphorus. The core sections were also analysed for total phosphorus and per cent organic content to determine the vertical and areal variability of phosphorus within the littoral sediments of Esthwaite Water.3. The rate of release of phosphorus from intact sediment cores was measured in the laboratory as a function of the pH of overlying water, yielding the relationship log K=0.54pH-3.94, K=mgPm"^day"'. The maximum release rate measured was 75mgPm"^ day"' at pH = 10.5.4. Experiments on sediment slurries indicate that the release of phosphorus at pH 10 is rapid with approximately 50% of the total NaHCO^+NaOH extractable phosphorus being released within 3 h. 5. Phosphorus release from the littoral sediments may equal or exceed external sources plus hypolimnetic inputs during periods of high pH associated with times of maximum algal biomass.

“…1, residual phosphorus (mainly organic phosphorus) was often more than half of the total phosphorus content and reached a maximum at 90.6% in the sediment of the oligotrophic and acidified Lake Stora Hastevatten. The minimum of 5.8% in the Flaming Gorge reservoir (Messner et al, 1984) was probably caused by a substantial sedimentation of allochtonous inorganic material.…”

Phosphorus in sediments — speciation and analysis

Characterization of sediment phosphorus is commonly based on sequential chemical extractions, in which phosphorus is supposed to be selectively removed from different compounds in the sediments. The first extraction schemes were designed to quantify discrete chemical or mineralogical compounds. As extraction schemes have been tested on different sediments, several systematic errors have been detected and the schemes have been modified and simplified accordingly. Other chemical extractions or treatments have attempted to determine phosphorus bound to particles with a certain strength or binding energy, the purpose being to determine the labile, loosely bound, exchangeable, mobile or algal-available fraction of sediment phosphorus. All extraction procedures yield operationally defined fractions and cannot be used for identification of discrete phosphorus compounds. The many methodological modifications make it necessary to be cautious when comparing results from the literature in this field.

“…By making direct chemical measurements on a quasi-natural system, data more related to actual reservoir conditions may be obtained. Gunnison et al (1980), have proposed a simulation technique that relies on 250 L reaction vessels, and Messer et al (1984) have used a simulation method to estimate nutrient release rates from sediment cores from Flaming Gorge Reservoir, Utah, U.S.A. Thus, sedimentwater simulation techniques may be applied to planned or existing reservoirs (or lakes) to study a variety of chemical processes associated with naturaJ sedimentwater interactions or to evaluate the effects of perturbations to a natural system.…”

The technique of microcosm sediment-water simulation was used to obtain predictive water quality data for the proposed Jordanelle Reservoir, Heber City, Utah. Sediment-water microcosms were prepared for four sites located in the north arm of the reservoir basin, including two sites located in an abandoned acid mine tailings pond. Data obtained from the tailings pond microcosms indicated that low pH water and high trace metal concentrations may exist in this area of the reservoir. These data suggested that the tailings material should be contained or removed prior to reservoir filling. Other sites in the reservoir basin exhibited water quality considered normal for reservoirs of similar elevation and basin geology. Near the proposed dam, anaerobic conditions could develop rapidly due to available concentrations of organic carbon, and the subsequent release of Zn, Fe, and Mn may pose a water quality problem. At the sampling site near Keetley, simulation data indicated that anaerobic conditions will not develop as quickly or be as severe as conditions expected near the dam. Overall, the availability of nitrogen and phosphorus in the Provo River and Jordanelle sediments indicated that problems with algal blooms may exist in the reservoir. Also presented is a brief discussion of the advantages and disadvantages associated with microcosm sediment-water simulation.
