“…[5,6] For example, although near-edge X-ray fine structure spectroscopy (NEXAFS) essentially meets the first four criteria (at least for particulate matter) the technique requires access to a synchrotron X-ray beam line. [125] In the short term HPLC possibly offers the best approach for the routine analysis of organic P in aquatic samples.…”

“…That being said, one of the main reasons for the lack of progress in this area is the limited availability of suitable tools and techniques to easily and routinely quantify and characterise organic P in environmental samples. Although there have been a plethora of approaches to the characterisation and quantification of organic P in the aquatic environment [2][3][4][5][6][7] each approach has its limitations. Attempts to quantify and characterise organic P in aquatic ecosystems have ranged from the very simple to the technologically advanced.…”

Environmental context. Organic phosphorus can be one of the major fractions of phosphorus in many aquatic ecosystems. This paper discusses the distribution, cycling and ecological significance of five major classes of organic P in the aquatic environment and discusses several principles to guide organic P research into the future.Abstract. Organic phosphorus can be one of the major fractions of phosphorus in many aquatic ecosystems. Unfortunately, in many studies the 'organic' P fraction is operationally defined. However, there are an increasing number of studies where the organic P species have been structurally characterised -in part because of the adoption of 31 P NMR spectroscopic techniques. There are five classes of organic P species that have been specifically identified in the aquatic environment -nucleic acids, other nucleotides, inositol phosphates, phospholipids and phosphonates. This paper explores the identification, quantification, biogeochemical cycling and ecological significance of these organic P compounds. Based on this analysis, the paper then identifies a number of principles which could guide the research of organic P into the future. There is an ongoing need to develop methods for quickly and accurately identifying and quantifying organic P species in the environment. The types of ecosystems in which organic P dynamics are studied needs to be expanded; flowing waters, floodplains and small wetlands are currently all under-represented in the literature. While enzymatic hydrolysis is an important transformation pathway for the breakdown of organic P, more effort needs to be directed towards studying other potential transformation pathways. Similarly effort should be directed to estimating the rates of transformations, not simply reporting on the concentrations. And finally, further work is needed in elucidating other roles of organic P in the environment other than simply a source of P to aquatic organisms.

“…For the rural rivers, relatively higher DO levels were found in the water (Table 1) and TN increased at similar rates. PN originates from phytoplankton, plankton, bacteria, and organic detritus found in water [23], whereas effluent from wastewater treatment plants contain large quantities of organic particulate matter [11]. Thus, PN levels in the urban rivers were greater than those in the rural rivers.…”

“…The relationships between different forms of P and N were summarized as follows [23]. Particulate phosphorus (PP) was determined as the difference between TP and TDP, and dissolved nonreactive phosphorus (DNP, sometimes defined as dissolved organic P) was determined as the difference between TDP and SRP.…”

Nutrient inputs from rivers play an important role in lake eutrophication. To compare the forms characteristics of phosphorus (P) and nitrogen (N) in rivers flowing through rural and urban areas, water samples were collected seasonally from five urban rivers and six rural rivers flowing to Lake Chaohu, China. Higher total phosphorus (TP), particulate phosphorus (PP), soluble reactive phosphorus (SRP), and dissolved nonreactive phosphorus (DNP) concentrations and SRP/TP percentages were observed in urban rivers than in rural rivers, and PP/TP and DNP/TP ratios were lower in urban rivers than in rural rivers. The concentrations of total nitrogen (TN) and all N forms other than dissolved organic nitrogen (DON) were significantly higher in urban rivers than in rural rivers. NH4 + /TN levels were higher in urban rivers, whereas PN/TN and DON/TN ratios were significantly lower in urban rivers compared with rural rivers. NO3 − /TN and NO2 − /TN levels were similar between the two groups of rivers. TP, BD-P, and NaOH-P levels in urban river surface sediments were significantly higher than those in rural rivers. NaOH-P/TP ratios were significantly elevated in urban rivers, whereas HCl-P/TP and Res-P/TP ratios were significantly lower compared with rural rivers. Urban rivers have transferred large quantities of NH4 + and SRP into Lake Chaohu, resulting in higher TP and TN levels and and SRP into urban rivers is a high priority for mitigating eutrophication and algal blooms in Lake Chaohu.

“…Nitrogen and phosphorus, which are restrictive nutrients, play a great role in terms of inducing algae growth and biological production in the aquatic ecosystem. Therefore, dispersion of high amounts of nitrogen and phosphorus into water sources give rise to the odds of eutrophication taking place and creates an impact on water quality [3].…”

Lake Uluabat, having an international significance and subject to the Ramsar Convention, is fed by the basin of Mustafakemalpaşa Stream which runs through fertile lands utilized for livestock breeding and agriculture. In this study, total amount of nitrogen (TN) and phosphorus (TP) loads of non-point pollutants (agriculture, livestock breeding, vegetation, surface runoff and small settlements) was calculated. It was found out that most intensive pollution load stemmed from livestock breeding which causes dispersion of 13653.57 tons·year −1 of TN and 3224.45 tons·year −1 of TP into the Lake Uluabat. Additionally, seasonal changes in concentration of TN and TP were observed during the period of [2008][2009] in Lake Uluabat. It was concluded that the rise of agricultural activities in summer months was the reason underlying the increase in pollution during the months in question.
