ABSTRACTTo better understand the cycling of marine dissolved organic matter, analytical methods are required allowing for data on dissolved organic nitrogen and phosphorus (DON and DOP) to be acquired with high analytical performance. The coverage of documented DON and DOP analytical performance is very limited; instead analytical data are mostly ...

Utilization of dissolved organic phosphorus by different groups of phytoplankton taxa
Harmful Algae, 2011The utilization of nine dissolved organic phosphorus (DOP) compounds by five bloom-causing phytoplankton species was studied under batch culture conditions. The DOP compounds included were adenosine 5-triphosphate (ATP), adenosine 5-monophosphate (AMP), cytidine 5-monophosphate (CMP), guanosine 5-monophosphate (GMP), uridine 5-monophosphate (UMP ...

Environmental Pollution
The utilization of dissolved organic phosphorus (DOP) driven by alkaline phosphatase hydrolysis contributes significantly to mitigating coastal nitrogen pollution through alleviating phosphorus (P) limitation. However, the lack of a parameterization for this process limits the quantitative assessment of its impact on marine nutrient pollution and ...

Dissolved organic phosphorus: An indicator of organic matter turnover?
Estuarine, Coastal and Shelf Science, 2012Abstract Seasonal and interannual variations of dissolved organic phosphorus (DOP) are analysed for five stations in the Dutch Wadden Sea (southern Wadden Sea, 1991–2007) and one station in the northern Wadden Sea (List tidal basin near Sylt, 2000–2009).

Molecular insight into the variation of dissolved organic phosphorus in a wastewater treatment plant
Water Research, 2021To date, eutrophication becomes a great concern of vulnerable aquatic systems. Dissolved organic phosphorus (DOP) discharged from wastewater treatment plant (WWTP) holds a large source of phosphorus in receiving water. However, due to the complexity of DOP, their variation and fate in WWTP remain unknown at the molecular level, and are always ...

Dynamics of dissolved organic phosphorus in the nearshore of eastern Lake Erie
Aquatic Ecosystem Health & Management, 2023Abstract The east basin of Lake Erie continues to suffer from blooms of filamentous green algae (primarily Cladophora). Potential management action through reduced phosphorus loadings have and continue to focus on the dissolved inorganic phosphorus pool but other potentially bioavailable phosphorus pools are not always considered.

The availability of dissolved organic phosphorus compounds to marine phytoplankton
Chinese Journal of Oceanology and Limnology, 1995The availability of three dissolved organic phosphorus (DOP) compounds as nutrient sources for experimental culture of three algae was studied. Results indicated that these compounds could be utilized by algae, and that dissolved inorganic phosphorus (DIP) was first to be uptaken when various forms of phosphorus (DIP and DOP) co-existed.Dicrateria ...

A re-examination of the measurement of dissolved organic phosphorus in seawater
Marine Chemistry, 1990Abstract The standard UV irradiation and autoclave-promoted persulphate oxidation methods for the determination of dissolved organic phosphorus in seawater have been re-evaluated and tested against a new method which incorporates both the UV and persulphate oxidation methods.

Abstract Analytical procedures to determine lipid phosphorus (lipid P) in seawater were developed and tested using a combination of solvent and solid-phase extraction. Lipid P was extracted from particulate and dissolved matter in seawater with a solvent mixture of chloroform and methanol.

Abstract The sorption of phosphate on lake sediments has a major influence on transport, degradation, and ultimate fate of phosphorus (P) in lake ecosystem. Organic P is abundant in sediments and is an important P speciation for primary productivity. Organic P can also be transferred from sediments into the overlying water and supplies nutrition for ...
