Abstract:
... The seasonal changes in dissolved organic matter (DOM), and its correlation with the release of internal nutrients during the annual cycle of cyanobacteria in the eutrophic Lake Chaohu, China, were investigated from four sampling periods between November 2020 and July 2021. The DOM fluorescence components were identified as protein-like C1, microbial humic-like C2, and terrestrial humic-like C3. T ...
... High phosphorus steel slag and carbonized rice husk are two common wastes characterized by high generation and low secondary use values. Through the reduction of high phosphorus steel slag by biomass, both wastes were fully utilized, thus reducing the negative impact on the environment. In this study, variables such as temperature, time, and amount of reactants were changed to determine the optima ...

Abstract:
... The effects of long-term excessive phosphorus (P) fertilization on the P fraction changes and P loss risk in orchard soils remain unclear. This study aimed to assess the concentrations of and relationships among the soil total P (TP), Olsen-P and P fractions in pomelo orchard (PO) soil during different fertilization periods. The PO soils were in a severe P overapplication state (905.4 kg P₂O₅ ha⁻¹ ...

Abstract:
... Phosphorus is an indispensable nutrient element in agriculture and its reserves are limited. To secure a sustainable supply of phosphorus, phosphate recovery from dephosphorization slag generated in steelmaking was considered a promising solution. In this study, acid leaching was adopted to separate the P-concentrating solid solution from dephosphorization slag. Selective leaching of P from slags ...

Abstract:
... Significant differences in the morphological and physiological characteristics of submerged macrophytes have been studied following nutrient addition, but little research has investigated the changes in plant trait network topology structures and trait interactions at the whole-plant perspective along nutrient gradients. Plant trait interactions and coordination strongly determine ecosystem struct ...

Abstract:
... The long-term accumulation, burial and release of nutrients, such as carbon (C), nitrogen (N), and phosphorus (P) in lacustrine sediments are responsible for the global lake eutrophication. Interpretation of the spatiotemporal sedimentary record of nutrients (C, N, and P) in contrasting trophic level of lakes is helpful for understanding the evolutionary process of water eutrophication. Based on t ...

Abstract:
... Biofilm carriers can avoid microorganism washout while maintaining a high amount of biomass, but are also associated with a long biofilm formation period and biofilm aging. A single stage partial nitritation/anammox process (single stage PN/A) reactor was setup to study the biofilm growth characterization and treatment performance under an NLR of 0.53 to 0.90 gN/L/d over one year. Biofilm growth w ...

Abstract:
... Iron (Fe) (oxyhydr)oxides and organic matter (OM) are important hosts of geogenic phosphorus (P) in groundwater systems. However, the coupled influence of Fe (oxyhydr)oxides and OM on the occurrence and mobility of P in groundwater remains unclear. In this study, we shed light on the underlying mechanisms of the control of Fe (oxyhydr)oxides and OM on P mobilization in the alluvial-lacustrine aqui ...

Abstract:
... Developing a suitable substrate with high phosphorus (P) sorption capacity, low solubility, and high hydraulic loading for constructed wetlands (CWs) is crucial for their functions. In this study, we used attapulgite and biochar as base materials to prepare a lanthanum/aluminum (La/Al) amended attapulgite/biochar composite as a novel P filter using a one-step drying process and subsequent high-tem ...
... From environmental waste to energy storage, waste boxes converted into conductive electrodes to further grow active materials has been an interesting way of upcycling. In this study, we transformed waste boxes of KIMTECH Kimwipes® into conductive f-MWCNTs light and flexible substrate (LFS) as current collectors. Then, undoped and P-doped active materials consisting of layered quadruple hydroxides ...
... Herein we report selective P–C and P–N chemistry as a new synthetic tool for constructing phosphorus (P)-chromophores with rich chemical structures. Our studies reveal that isomeric structures significantly influence the chemical structure and electronic communication of P-heteropines, which results in efficient tunability of the photophysical properties. In particular, isomeric P-chromophores wit ...
... Competition between polyphosphate- and glycogen-accumulating organisms (PAOs and GAOs) is problematic in the enhanced biological phosphorus removal (EBPR) process. Aiming at a high phosphorus removal efficiency (PRE), the phosphorus release amount (PRA) is considered an essential evaluating indicator. However, the correlations between PRE and PRA and the abundance of PAOs are not clear. In this st ...
... AIMS: This study assessed the impact of combined lime and phosphorus application on soil pH, plant availability of added phosphorus and crop yield over time. METHODS: In a series of long-term field trials started in 1936 on a clayey soil in south-west Sweden, acidic superphosphate and basic Thomas phosphate were tested in combination, with and without an initial high dose of lime. RESULTS: Liming ...
... Novel intra-boll yield component traits and fiber quality indices have been used by breeders to select suitable Gossypium hirsutum L. lines, but there is little research on how these traits change during cultivation practices, especially fertilizer application. We hypothesized that these novel traits have obvious responses to phosphorus (P) fertilizer, which would explain the variation in yield an ...
... It is well established that shallow tillage (ST) and no-tillage (NT) of cultivated soils can have higher risk of dissolved phosphorus (P) loss during runoff than conventional tillage (CT). However, quantitative descriptors of how differences in tillage practices influence soil P sorption properties and how these properties in turn influence dissolved P loss remain lacking. Moreover, the influence ...

Abstract:
... The salinity may affect the phosphorus (P) determination accuracy in coastal waters, especially for the dissolved non‐reactive P (DNRP) and total dissolved P (TDP). In this work, the competition mechanism between NaCl and DNRP for oxidants (K₂S₂O₈, the most commonly used and recognized oxidant) was identified in different DNRP determinations. Furthermore, salinity influences on determinations of t ...
