Developing novel coating materials for fast and sensitive solid-phase microextraction(SPME) is highly desired but few are achieved. A new material of metal-organic framework(MOF)-derived hollow carbon nanocubes(HCNCs) was prepared as a fiber coating material for SPME. The HCNCs-coated fiber(denoted as HCNCs-F) exhibited a better enrichment performance than solid carbon nanocubes(SCNCs)-coated fiber(denoted as SCNCs-F) and commercial fibers based on the abundant active sites of the hollow structure, hydrophobic interactions, and π-π interactions. Moreover, because of the reduced mass-transport lengths of the hollow mesoporous structure, the HCNCs-F demonstrated a faster mass transfer compared with the SCNCs-F. The HCNCs-F was used to determine the six hydrophobic polycyclic aromatic hydrocarbons(PAHs) with wide linear ranges, good reproducibility, and low detection limits. Finally, the HCNCs-F was successfully applied for the determination of PAHs from the real water samples.

Soil organic nitrogen (SON) decomposition is a fundamental process in the nitrogen (N) cycle that influences N availability for plant uptake and soil health. However, the long-term effects of nutrient fertilisation on SON decomposition and its microbial drivers remain poorly understood. Here, we used the 180-year-old Broadbalk Winter Wheat Experiment to investigate how farmyard manure (FYM), mineral fertiliser (NPK), and no fertilisation input (NIL) affect crop yield, SON turnover, microbial community composition, and functional genes. Our findings showed that distinct and complementary microbial mechanisms regulate SON decomposition under different nutrient fertilisation treatments. FYM application increased gross N mineralisation to 43.1 mg N kg−1 soil d−1, by doubling microbial biomass and promoting bacterial-dominated protein and peptide decomposition. During the early stage of decomposition, CO2 release from protein and peptide turnover under FYM increased by 96 % and 44 %, respectively, compared to NIL. NPK fertilisation enhanced the decomposition of complex N compounds and promoted the turnover of high-molecular-weight N to support microbial growth by upregulating N-cycling genes and extracellular enzyme production. The carbon use efficiency of protein was increased to 0.68. NPK fertilisation also stimulated fungal and Actinobacteria populations, accelerating the turnover rate of peptides and amino acids to 22.7 and 2.4 mg N kg−1 soil d−1, respectively. These results provide new insights into how nutrient fertilisation practices affect microbialy-mediated N dynamics and crop productivity, emphasising the importance of microbial functional diversity in supporting soil N cycling and fertility. © 2025 Elsevier Ltd

The presence of trivalent arsenic (As(III)) in aquatic environments constitutes a persistent and substantial threat to the safety and quality of human drinking water resources. In response to this issue, we developed an innovative catalyst by synthesizing a nickel-doped zeolitic imidazolate framework (Ni-ZIF-L) through a multi-solvent approach at ambient temperature. Specifically designed to remove As(III) from aqueous environments, the Ni-ZIF-L catalyst, particularly the 5 % Ni-ZIF-L variant achieved through precise nickel-to-zinc ratio adjustment, demonstrated exceptional catalytic effects. Experimental findings revealed a significant enhancement in the catalytic performance of ZIF-activated peroxymonosulfate (PMS) via nickel doping. The 5 % Ni-ZIF-L catalyst demonstrated robust As(III) removal efficiency across diverse operational conditions, including varying catalyst and PMS dosages, initial As(III) concentrations, pH levels, and coexisting inorganic anions. Fourier-transform infrared spectroscopy (FTIR), Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS) analyses demonstrated that As(III) was oxidized to As(V) and stabilized through As-O coordination. X-ray absorption near-edge structure (XANES) spectra explicitly confirmed the transition of adsorbed arsenic to a +5 oxidation state, consistent with As 2 O 5 , while extended X-ray absorption fine structure (EXAFS) fitting further revealed an As-O coordination shell with an atomic distance of 1.71 Å, corroborating the formation of stable As-O complexes. Radical quenching experiments identified singlet oxygen as the dominant reactive species driving arsenic oxidation. Overall, this research provides valuable insights for the development of novel ZIFs materials and the treatment of As pollution in wastewater.

Efficient and accurate assessment of water environmental risks is of great importance with severe environmental situation in developing nations. A hybrid cloud technique is proposed based on entropy theory and cloud model, particularly considering various uncertainties, randomness and fuzziness of the concept "eutrophication risk" and subjective uncertainties in weights calculations, in eutrophication risk assessment. In this approach, given eutrophication risk factors and corresponding levels, parameters of the cloud model under each factor are determined, and the assessment model is generated with hybrid weights based on Shannon entropy and the AHP. Eutrophication risks can be assessed with peaks of certainty degrees by the hybrid cloud model. Eutrophication risks of representative lakes have been assessed by the proposed approach. Results indicate that this technique is applicable in comparisons with conventional methods. © 2015 Taylor & Francis Group, London.

Granite red soil(GRS) and Quaternary red clay(QRC) are two typical erodible soils in the red-soil region of southern China. Analytical and comparative studies of the characteristics of runoff and sediment yield for the two soils at various slopes are currently needed. The purpose of the current study was to clarify the characteristics of runoff and sediment yield for GRS and QRC at different slopes and to establish models for estimating sediment yield for the two soils. Forty-eight runoff microplots with four slopes(5°, 15°, 25°, and 35°) and two soils(GRS and QRC) were established and exposed to natural rainfall. Runoff and sediment yield were measured 10 times during the study period. Runoff and sediment yield for the two soils under the various slopes had similar temporal variations, and both increased with prior cumulative erosive rainfall. Runoff for GRS and QRC was moderately temporally variable, with coefficients of variation(CVs) from 46.2% to 60.6%, and sediment yield for QRC was strongly temporally variable, with CVs from 114.8% to 145.8%. Sediment yield for GRS increased with slope, but sediment yield for QRC first increased and then decreased, with a calculated inflection point of 18°, but runoff for both soils decreased with slope. The CVs of both runoff and sediment yield with slope for the two soils ranged from 3.6% to 88.0%, lower than the temporal variabilities, indicating that rainfall may have a larger impact than slope on runoff and sediment yield for QRC and GRS. Under the various slopes, runoff and sediment yield for both soils increased with rainfall and sediment yield increased with runoff, but the proportions of effective rainfall and runoff differed. Pedotransfer-function models based on rainfall, runoff, and slope accurately estimated sediment yield for the two soils, with the model fit coefficient of determination(R2) > 0.81 and the R2for verification >0.79. These results improve the understanding of the laws governing erosion for differe

Thallium is an extremely toxic metal and abundant in industrial wastewater but little studied. In order to understand the optimal adsorption kinetic parameters of the chelating resin containing hydrazine wastewater, we carried out adsorption experiments on the cerium-containing wastewater treated by chemical precipitation. In this chapter, the optimum adsorption conditions, adsorption model, dynamic adsorption curve and desorption and regeneration of adsorbent were determined at different pH, temperature, adsorption time and different adsorbent dosage. The results show that the removal rate of thallium wastewater by resin is up to 97.5% when the pH value is 9. The optimum adsorption temperature is 30 and the adsorption reached equilibrium at 80 min. The adsorption process is consistent with Lagergren quasi-second-order adsorption and Langmuir isotherm model. The regenerative properties of the resin show that the resin adsorption rates still reach 95.8% after repeat use for six times. In summary, the chelating resin has good adsorption and reusability to the thallium-containing wastewater. © The Authors, published by EDP Sciences, 2019.
