Trends in data from recent years show movement toward eutrophication in Otsego Lake; these include increasing total phosphorus and resultant increasing chlorophyll a concentrations, decreasing Secchi transparency readings and decreasing hypolimnetic oxygen concentrations(Harman et al., 1997). The increase in phosphorus has triggered the changes in chlorophyll a, Secchi transparency, and dissolv...

Laboratory studies have indicated that calcite may be used in separate, exchangeable filter units in constructed wetland systems to remove phosphorus. Based on these studies we built a full-scale experimental constructed wetland with a calcite-based filter unit to study its performance, under real-life conditions. The system consists of a 2-m3 sedimentation tank and two vertical flow constructe...

The rebuilding of the phosphorus cycle can be performed with the use of both biotechnology and chemical technology. This paper presents a review of the phosphorus cycle and the different approaches that can be taken to the recovery of phosphorus from phosphate-rich waste. Critical issues in the phosphorus cycle are also discussed. Methods for the recovery of phosphorus form sewage sludge ash ar...

To compare phosphorus intake and renal phosphorus regulation between thermally injured patients and multiple trauma patients, 40 consecutive critically ill patients, 20 with thermal injury and 20 with multiple trauma, who required enteral tube feeding were evaluated. Phosphorus intakes were recorded for 14 days from the initiation of tube feeding which was started 1 to 3 days postinjury. Serum ...

diversification of phosphorus sources can bring substantial synergy effects within all thesustainable development domains: environmental, economic and social, and such an opportunity should not beoverlooked. urban sinks accumulate phosphorus and other elements and may serve as sources of secondaryraw materials. this paper evaluates phosphorus sources based on their total material requirement (t...

High calcium intake has been associated with an increased risk of advanced-stage and high-grade prostate cancer. Several studies have found a positive association between phosphorus intake and prostate cancer risk. We investigated the joint association between calcium and phosphorus and risk of prostate cancer in the Health Professionals Follow-Up Study, with a focus on lethal and high-grade di...

This study focused on water quality for Guanting Reservoir, the possible auxiliary drinking water source of Beijing. Through remote sensing (RS) approach, water quality retrieval models were established and analyzed for eight common concerned water quality variables, including algae content, turbidity, and concentrations of chemical oxygen demand, total nitrogen, ammonia nitrogen, nitrate nitro...

The total concentration of zinc, iron, nitrogen and phosphorus, as well as their water and acetic acid extractable forms – nitrate nitrogen, ammonium nitrogen and phosphate phosphorus – were determined in st. John’s wort herb (Hypericum perforatum l.) yarrow herb (Achillea millefolium l.), nettle leaves (Urtica dioica l.) and birch leaves (Betula pendula roth.), collected from four natural loca...

The abundance and relevance ofAccumulibacter phosphatis (presumed to be polyphosphate-accumulating organisms [PAOs]), Competibacter phosphatis (presumed to be glycogen-accumulating organisms [GAOs]), and tetrad-forming organisms (TFOs) to phosphorus removal performance at six full-scale enhanced biological phosphorus removal (EBPR) wastewater treatment plants were investigated. Coexistence of v...
