Organic phosphorus species in surface sediments of a large, shallow, eutrophic lake, Lake Taihu, China
TLDR
The proportion of extracted organic P tototal P in sediments was negatively correlated with total P in the water column, as were the proportions for orthophosphate monoesters and DNA, which implies that the majority of organic P in surface sediments is likely stabilized in some way, and does not directly contribute to the internal loading of P from sediments.About:

In situ, high-resolution imaging of labile phosphorus in sediments of a large eutrophic lake
Shiming Ding,Chao Han,Yanping Wang,Lei Yao,Yan Wang,Di Xu,Qin Sun,Paul N. Williams,Chaosheng Zhang +8 more
TL;DR: In situ, high-resolution profiling of labile P with DGT is a more reliable approach and will significantly extend the ability in in situ monitoring of the labile status of P in sediments in the field.

Levels and distributions of organophosphate flame retardants and plasticizers in sediment from Taihu Lake, China
TL;DR: The concentrations and distribution of seven organophosphate flame retardants and plasticizers were investigated in 28 sediment samples collected from Taihu Lake and implied that there is an obvious emission source nearby at Suzhou City; in addition, human activities also play an important role in the concentration of OPs in the sediment.

Characterization of organic phosphorus in lake sediments by sequential fractionation and enzymatic hydrolysis.
Yuanrong Zhu,Fengchang Wu,Zhongqi He,Jianyang Guo,Xiaoxia Qu,Fazhi Xie,John P. Giesy,John P. Giesy,Haiqing Liao,Fei Guo +9 more
TL;DR: The results suggest that the biogeochemical cycle of bioavailable Po might play an important role in maintaining the eutrophic status of lakes.

A high-resolution dialysis technique for rapid determination of dissolved reactive phosphate and ferrous iron in pore water of sediments
TL;DR: A novel high-resolution dialysis technique was developed for rapid sampling of dissolved reactive phosphate (DRP) and ferrous iron in pore water at a vertical resolution of 2mm, verifying the control of P mobilization by Fe in sediments.
Journal ArticleDOI
In situ, high-resolution evidence for iron-coupled mobilization of phosphorus in sediments.
TL;DR: Direct evidence for the coupling between Fe and P in sediments is provided and the easily reducible Fe (oxyhydr)oxide species involved in the coupling process is identified, indicating that this solid phase should retain P prior to its release.

Development of a sequential extraction method for different forms of phosphorus in marine sediments
TL;DR: A sequential extraction method (SEDEX) was developed to separate five sedimentary P reservoirs: loosely sorbed P; ferric iron-bound P; authigenic carbonate fluorapatite + biogenic apatite+ CaCO3-associated P; detrital apatitic P; and organic P.

Phosphorus-31 nuclear magnetic resonance spectral assignments of phosphorus compounds in soil NaOH–EDTA extracts
TL;DR: In this paper, a solution 31P NMR chemical shifts of model P compounds, including inorganic phosphates, orthophosphate monoesters and diesters, phosphonates, and organic polyphosphates, were determined in a standardized soil P extractant (0.25 M NaOH and 0.05 M EDTA).
