Chemical composition, sources, and ecological effect of organic phosphorus in water ecosystems: a review
Bibliographic record
Abstract
Abstract Phosphorus (P) affects the water–air CO 2 flux through primary productivity, and affects the changes of carbon cycle and ecological environment in the global world. Organic phosphorus (Po) is an important P component in water environments. Various processes control the formation and transformation of Po and outbreaks of algal blooms. Here, research topics on Po in global water over the past 50 years are systematically reviewed to understand the progress in the (i) Po pretreatment techniques in various media, (ii) technical methods and qualitative and quantitative research on chemical composition of Po and bioavailability, (iii) source analysis of and factors affecting Po in different media of water environments and biogeochemical processes, (iv) interactions among Po, organic matter, and minerals, and their environmental behaviors, and (v) quantification of material exchanges at the sediment–water interface, interfacial processes, and ecological effects. Finally, the future research directives regarding Po in water environments are discussed. The findings provided an important scientific basis to formulate and revise global standards for water nutrients and a better understanding of water eutrophication and its control. Graphical Abstract

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
