Dissolved organic phosphorus: An indicator of organic matter turnover?

Estuarine, Coastal and Shelf Science, 2012
Abstract 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 weight distribution of phosphorus fraction of aquatic dissolved organic matter

Chemosphere, 2013
This study characterized dissolved organic phosphorus (DOP) that is discharged from the Everglades Agricultural Area as part of the larger pool of aquatic dissolved organic matter (DOM). Whole water samples collected at the Everglades stormwater treat area 1 West (STA-1 W) were fractionated using a batch ultrafiltration method to separate organic ...

Dissolved organic phosphorus enhances arsenate bioaccumulation and biotransformation in Microcystis aeruginosa

Environmental Pollution, 2019
Only limited information is available on the effects of dissolved organic phosphorus (DOP) on arsenate (As(V)) bioaccumulation and biotransformation in organisms. In this study, we examined the influence of three different DOP forms (β-sodium glycerophosphate (βP), adenosine 5'-triphosphate (ATP), and D-Glucose-6-phosphate disodium (GP) salts) and ...

DISSOLVED ORGANIC PHOSPHORUS EXCRETION BY MARINE PHYTOPLANKTON^1,2

Journal of Phycology, 1970
SUMMARYThe amounts of extracellular dissolved organic phosphorus (DOP) produced by 8 species of marine planktonic algae under various conditions of light, salinity, and nutrition were compared. Large amounts, more than 20% of the total P in the system, were excreted by Cyclotella cryptica, Thalassiosira fluviatilis, Dunaliella tertiolecta, and ...

Phosphorus Enhances Uptake of Dissolved Organic Matter in Boreal Streams

Ecosystems, 2017
Retention of carbon (C), either by physical mechanisms or microbial uptake, is a key driver of the transformation and storage of C and nutrients within ecosystems. Both the molecular composition and nutrient content of organic matter influence the rate at which it is retained in streams, but the relative influence of these characteristics remains ...

Processes Influencing Dissolved Organic Nitrogen, Phosphorus and Sulphur in Soils

Chemistry and Ecology, 1993
Abstract The influence of different plant and soil processes on the concentrations of soluble organic forms of carbon, nitrogen, phosphorus and sulphur in soil and drainage waters is reviewed. Current knowledge about soluble organic matter is restricted mainly to dissolved organic carbon.

The availability of dissolved organic phosphorus compounds to marine phytoplankton

Chinese Journal of Oceanology and Limnology, 1995
The 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 ...

Mineralization of dissolved organic phosphorus from a shallow eutrophic lake

Hydrobiologia, 1991
Release of soluble reactive phosphorus (SRP) from dissolved organic phosphorus (DOP), concentrated by reverse osmosis of water samples from Lough Neagh Northern Ireland, was measured in the presence of enzymes and cultures of lake water bacteria in a basal liquid medium adjusted to the pH of lake water (7.6).

Partitioning Dissolved Inorganic and Organic Phosphorus Using Acidified Molybdate and Isobutanol

Soil Science Society of America Journal, 1992
Abstract Quantification of P‐mineralization rate in soil using isotopic dilution requires that soluble inorganic 32 P ( 32 P i ) be determined without interference from soluble organic
