Chromium (Cr) accumulating in soil caused serious pollution to cultivated land. At present, nano zero-valent iron (nZVI) is considered to be a promising remediation material for Cr-contaminated soil. However, the impact on the behavior of Cr in the soil-rice system under high natural geological background value remains unknown. We studied the effects of nZVI on the migration and transformation of Cr in paddy soil-rice by pot experiment. Three different doses of nZVI (0, 0.001% and 0.1% (w/w)) treatments and one dose of 0.1% (w/w) nZVI treatment without plant rice were set up. Under continuous flooding conditions, nZVI significantly increased rice biomass compared with the control. At the same time, nZVI significantly promoted the reduction of Fe in the soil, increased the concentration of dissolved Fe and bioavailable Cr, then facilitated the absorption of Cr in rice roots and the transportation to the aboveground part. In addition, the enrichment of Fe(III)-reducing bacteria and sulfate-reducing bacteria in soil provided electron donors for Cr oxidation, which helps to form bioavailable Cr that is easily absorbed by plants. There is an unexpected environmental risk associated with nZVI application to the high geological background contaminated paddy soil, and one should be aware this risk when applying nZVI aiming to minimize human Cr exposure health risks via rice consumption. © 2023, The Authors.

Fine particulate matter(PM)and ozone(O),two globally signifcant air pollutants,have exerted substantial adverse impacts on climate and human health[1].From 2013 to 2020,China has achieved a signifcant decline of PMlevels,though O3pollution has deteriorated over time[2].PM-Oco-pollution includes not only both high levels of PMand O,but also high PMor Oeven when the other remain ***,the coordinated control of PMand Oshould not only focus on reducing high concentrations of PMand Osimultaneously.

Iodine plays a significant role in industry and in chemical processes within living organisms. However, radioiodine exposure possess threats such as thyroid cancer to humans, when they are released into the environment when using nuclear technology and through nuclear accidents. Its capture and storage is critical to safeguard industrial applications while preventing environmental leakages. Herein we report efficient radioiodine capture using a hierarchical nitrogen-doped, large surface area, nanoporous carbon derived from ultrasonication of ZIF-8. The carbon exhibited high adsorption capacity of 434 wt% gravimetrically and 1418 mgg-1 in cyclohexane solution with fast kinetics and high recoverability. We deduced the high adsorption capacity to be due to the large surface area with micro and mesopores, presence of hydroxyl groups acting as electron donors and the presence of nitrogen, which interacts strongly with the electron‐deficient iodine (I2). Moreover, the process best fits the pseudo-second-order and Freundlich models with multilinearity observed with Webber-Morris model. Because of its comparatively lower cost, large surface area, facile preparation, good regeneration and fast kinetics, the as-prepared porous carbon shows exceptional promise as radioiodine adsorbent. © 2021, CC BY.

Here, a H. uvarum – Saccharomyces cerevisiae mixed-fermentation was used to ferment fruit wines. Three fruit wines' volatile aroma characteristics were analyzed by headspace–solid-phase microextraction–gas chromatography-mass spectrometry. The results showed that the H. uvarum – S. cerevisiae fermented R. roxburghii, blueberry, and plum fruit wines further enriched their flavor characteristics. The overall flavor characteristics of sequentially-inoculated fruit wines differed significantly from those fermented with S. cerevisiae alone, although several similarities were also observed. Sequential inoculation of H. uvarum and S. cerevisiae positively affected the mellowness of the wine and achieved a better harmony of the overall wine flavors. In particular, H. uvarum – Saccharomyces cerevisiae mixed-fermentation produced blueberry wine had the widest variety and content of aroma compounds among the fermented wines. Therefore, H. uvarum – Saccharomyces cerevisiae mixed-fermentation inoculation in the three fermented fruit wines increased the aroma compound variety and content, thus enriching their aroma richness and complexity. © 2022, The Authors.

The harmless disposal, resource recovery, and synergistic efficiency reduction of municipal sludge have been the research focuses for the last few years. Calcium peroxide (CaO2) is a multifunctional and safe peroxide that produces an alkaline oxidation environment to promote the fermentation of municipal sludge to produce hydrogen (H2) and volatile fatty acids (VFAs), thus realizing sludge resource recovery. This review outlines the research achievements of CaO2 in sludge resource recovery, improvement of sludge dewaterability, and removal of pollutants from sludge in recent years. Meanwhile, the mechanism of CaO2 and its influencing factors have also been comprehensively summarized. Finally, the future development direction of the application of CaO2 in municipal sludge is prospected. This review would provide theoretical reference for the potential engineering applications of CaO2 in improving sludge treatment in the future. © 2024 Elsevier Ltd

With the increase in plastic products, the content of microplastics in waste activated sludge (WAS) has also increased, affecting its subsequent process. This research probed into the influence of predominant microplastics on the generation of volatile fatty acids (VFAs) throughout the anaerobic digestion process of WAS. The results revealed that the VFA production in the microplastic addition group was reduced compared to the control group, with reductions ranging from 13.49% to 29.57%. While microplastics accelerated the dissolution of WAS, they inhibited the processes of hydrolysis and acidification, affected the proliferation of key microbes (norank_f_Bacteroidetes_vadinHA17, Ottowia, and Propioniclava), and decreased the abundance of genes related to hydrolysis and acidification (pfkb, gpmI, ilvE, aces). Furthermore, microplastics reduced the levels of key hydrolytic and acidogenic enzymes, suppressing hydrolysis and acidification. This study revealed the influence exerted by microplastics on the processof anaerobic digestion, which contributes to sludge reduction and resource utilization. © 2024, The Authors.

The coordination of cucurbit[5]uril (Q[5]) with lanthanide cations (Ln3+), in the presence of Cu2+ cations, led to the formation of 2D-network coordination polymers, which have been investigated using single crystal X-ray diffraction. Experimental results revealed that crystals were only readily affordable for the systems involving the lighter lanthanide cations (La3+, Ce3+, Pr3+, Sm3+, Eu3+ and Tb3+), with all six Ln3+-Q[5] complexes (1 ~ 6) exhibiting similar coordination mode at the cucurbit[5]uril (Q[5]), and forming 2D-network coordination polymers with a 2D supramolecular assembly. One complex was found to detect Adenine (A) and Uracil (U) with high selectively. © 2023, The Authors. All rights reserved.

Phenolic compounds and nitrogen in coal pyrolysis wastewater has become a limiting factor for industrial development, creating conflicts with the principles of sustainability and environmental protection. While denitrification technologies for municipal wastewater have been well-established, research on short-cut denitrification for coal pyrolysis wastewater remains relatively limited. By controlling operational parameters, the study aimed to investigate the effects of different pH levels, Dissolved Oxygen (DO), and external carbon sources on short-cut denitrification for coal pyrolysis wastewater. Under conditions of adequate alkalinity, changes in pH had no significant impact on Nitrogen Accumulation Ratio (NAR) and Total Nitrogen (TN) removal ratios. When DO concentrations were controlled within the range of 2.0 to 4.0 mg/L for 5 days, NAR gradually decreased, indicating that operating the reactor at lower DO concentrations was more conducive to maintaining higher NAR levels. When the COD ratio of methanol to crude phenol was 1:1 and 1:3, the denitrification ratios were 5.13 mg NO2--N/ (g vss∙h) and 3.94 mg NO2--N/ (g vss∙h), respectively. When only crude phenol was used as an external carbon source with a C/N ratio of approximately 4, TN removal efficiency reached 90.32%. However, the denitrification ratio decreased to 1.66 mg NO2--N/ (g vss∙h). The Gas Chromatography Mass Spectrometry (GC-MS) analysis results indicated that phenol was the primary electron donor in the denitrification process of the system. © 2023, The Authors.
