Abstract :

The deterioration of the urban thermal environment has seriously affected the quality of life of urban residents, and studying the optimal cooling landscape combination and configuration based on local climate zones (LCZs) is crucial for mitigating the thermal environment. In this study, the LCZ system was combined to analyze the spatial and temporal changes to the thermal environment in the central area of Fuzhou, and the 159 blocks in the core area were selected to derive the optimal LCZ combination and configuration. The conclusions are as follows: (1) From 2013 to 2021, the building layout of the study area became more open and the building height gradually increased. The high-temperature areas were mainly clustered in the core area; (2) The LSTs for low-rise buildings (LCZ 3 (41.67 degrees C), LCZ 7 (40.10 degrees C), LCZ 8 (42.61 degrees C), and LCZ 10 (41.85 degrees C)) were higher than the LSTs for high-rise buildings (LCZ 1 (38.58 degrees C) and LCZ 4 (38.50 degrees C)); (3) The thermal contribution index for low building types was higher for dense buildings (LCZ 3 (0.4331), LCZ 8 (0.3149), and LCZ 10 (0.2325)) than for open buildings (LCZ 6 (0.0247) and LCZ 9 (0.0317)); (4) Blocks with an average LST of 36 degrees C had the most cost-effective cooling, and the combination and configuration of LCZs within such blocks were optimal. Our results can be used to better guide urban planners in managing LCZ combinations and configurations within blocks (the smallest planning unit) at an earlier phase of thermal environment design, and for appropriately adapting existing block layouts, providing a new perspective on urban thermal environment research with important implications for climate-friendly city and neighborhood planning.

Abstract :

Lanthanum-type metal-organic frameworks (La-MOFs) can be used to mitigate phosphate pollution in wastewater. Herein, La-MOFs was gained via the solvothermal method and its phosphate removal property was examined under various conditions, like variable initial phosphate concentration, solution pH, and co-existing ions. The material morphology, element composition, and crystal morphology of the La-MOFs was characterized using XRD, SEM, FTIR, and XPS. The phosphate removal mechanism was investigated by combining thermodynamic and kinetic analyses. The La-MOFs exhibited superior adsorption capability for surplus phosphate in water, and also had a high selectivity for phosphate in the complexed environment with some co-existing ions. Maximum adsorption was obtained at pH 4. The sorption procedure of La-MOFs aligned more with the Langmuir and pseudo-second order kinetic models, demonstrating monomolecular-layer-controlled chemisorption. And the maximum sorption capacity was 73.69 mg g-1. Electrostatic interactions and ligand exchange, which enabled the development of an La-O-P inner-sphere complexation, were identified as the primary mechanisms of phosphate removal. This research provides insights into the optimal conditions and mechanism of phosphate adsorption by La-MOFs.

Abstract :

Despite the serious health threats due to wide use of organophosphorus pesticides (OPPs) have been experimentally claimed to be remediated by probiotic microorganisms in various food and organism models, the interactions between OPPs and probiotics in the natural wetland ecosystem was rarely investigated. This study delves into the spatial and temporal distribution, contamination levels of OPPs in the Baiyangdian region, the diversity of probiotic communities in varying environmental contexts, and the potential connection with OPPs on these probiotics. In typical shallow lake wetland ecosystem-Baiyangdian lake in north China, eight OPPs were identified in the lake sediments, even though their detection rates were generally low. Malathion exhibited the highest average content among these pesticides (9.51 ng/g), followed by fenitrothion (6.70 ng/g). Conversely, chlorpyrifos had the lowest detection rate at only 2.14%. The region near Nanliu Zhuang (F10), significantly influenced by human activities, displayed the highest concentration of total OPPs (136.82 ng/g). A total of 145 probiotic species spanning 78 genera were identified in Baiyangdian sediments. Our analysis underscores the relations of environmental factors such as phosphatase activity, pH, and electrical conductivity (EC) with probiotic community. Notably, several high-abundance probiotics including Pseudomonas chlororaphis, Clostridium sp., Lactobacillus fermentum, and Pseudomonas putida, etc., which were reported to exhibit significant potential for the degradation of OPPs, showed strongly correlations with OPPs in the Baiyangdian lake sediments. The outcomes of this research offer valuable insights into the spatiotemporal dynamics of OPPs in natural large lake wetland and the probability of their in-situ residue bioremediation through the phosphatase pathway mediated by probiotic such as Lactic acid bacteria in soils/sediments contaminated with OPPs.

Study of a New Photocatalytic Film Process Combined with a Constructed Wetland and an Analysis of Reoxygenation Pathways in a Water Body SCIE SSCI

Abstract :

Pollution in water environments hinders both social progress and economic development. Wastewater treatment and the sustainable use of water resources are important factors in solving this problem. In a previous study, the authors proposed a process that used photocatalytic film as a back-end treatment in a composite iron-carbon constructed wetland (WIC&PF) to restore a mildly eutrophic water body. This method has strong reoxygenation effects, and can efficiently remove pollutants; these are qualities that have not been mentioned in previous studies regarding constructed wetlands. In this study, the authors further investigated the effectiveness of this process by using a photocatalytic film as a front-end treatment for a composite iron-carbon constructed wetland (PF&WIC) to restore a mildly eutrophic water body. The results showed NH4+-N, TN, TP, COD, and chlorophyll a removal rates using PF&WIC of 79.1 +/- 6.6%, 76.8 +/- 6.5%, 77.0 +/- 5.4%, 77.3 +/- 7.2%, and 91.7 +/- 5.6%, respectively. The DO concentration of the water body increased compared with that of the effluent. The bacterial species and their abundance in the lake water also changed significantly, and photosynthetic autotrophic bacteria (Cyanobium PCC-6307) became the most dominant bacteria, and this played an important role in reoxygenating the water body. In comparing these results to those of our previous study, the removal of pollutants with PF&WIC was close to that with WIC&PF, but the reoxygenation effect of PF&WIC on the water body was significantly worse than that of WIC & PF; thus, WIC&PF is the more reasonable choice for treating eutrophic water bodies.

Abstract :

Diazinon is an organophosphorus pesticide widely used in agriculture and household pest control, and its use also poses several environmental and health hazards. In this study, we investigated the spatial and temporal distribution of diazinon in Baiyangdian, evaluated its potential ecological risk and toxicity to aquatic organisms based on RQ (Risk quotient) and TU (Toxic unit) analysis, and assessed the potential effects of diazinon accumulation on probiotics and pathogens based on statistical analysis of high-throughput sequencing data. The results showed that diazinon in Baiyangdian posed a low to moderate chronic risk to sediment-dwelling organisms and a low toxicity effect on aquatic invertebrates, which was mainly concentrated in October and human-intensive areas. Meanwhile, increases in sediment electrical conductivity (EC), amorphous iron oxides content and phenol oxidase activity favored diazinon accumulation in sediments, whereas the opposite was the case for sediment organic carbon, β-1,4-glucosidase, phosphatase, catalase and pH, suggesting that environmental indicators play a key role in the behavior and distribution of diazinon. In addition, diazinon in heavily contaminated areas seem to inhibit the rare probiotics (Bifidobacterium adolescentis and Serratia sp.), while promoted dominant pathogens (e.g., Burkholderia cenocepacia), which can lead to increased disease risk to humans and ecosystems, disruption of ecological balance and potential health problems. However, probiotic Streptomyces xiamenensis resist to diazinon would be a potential degrader for diazinon remove. In conclusion, this study unveiled the effects of diazinon pollution on wetland ecosystems, emphasizing ecological impacts and potential health concerns. In addition, the discovery of diazinon resistant probiotics provided new insights into wetland ecological restoration. © 2024 Elsevier Ltd

Abstract :

In the present work,Ce-La-MOFs@F3O4 composites were prepared via hydrothermal method,and the adsorption performance of Ce-La-MOFs@Fe3O4 on F- in aqueous solution was investigated,and the adsorption conditions were optimized by response surface method. The experimental results show that the best adsorption effect of Ce-La-MOFs@Fe3 O4 is achieved at pH = 3. 6,experimental temperature of 40 ℃, and initial fluoride ion concentration of 17. 4 mg / L,and the F- removal efficiency could reach 94. 5%. The experimental datas of fluoride removal were more suitable to be described by Langmuir isotherm model,and the maximum adsorption capacity (qmax)is 147. 23 mg / g. The thermodynamic parameters ΔGo,ΔHo and ΔSo indicated that the adsorption reaction is anentropy-increasing process with spontaneous heat absorption, and kinetic study show that the adsorption of F- by Ce-La-MOFs@Fe3 O4 is well fitted with the pseudo second order model. The morphology and structure of the composites were characterized and analyzed,and the adsorption mechanisms were explored in conjunction with the adsorption thermodynamic and kinetic studies,which were mainly a combination of ion-exchange action and electrostatic adsorption. The results of co-existing ion experiments and regeneration experiments show that Ce-La-MOFs @ Fe3 O4 has ahigh selectivity for F- . And the regeneration performance of Ce-La-MOFs @ Fe3 O4 is so excellent that the recovery rate can reach 96%. After two cycles,the removal efficiency still reached 81. 74% of F- © 2024 Cailiao Daobaoshe/ Materials Review. All rights reserved.

Abstract :

环境、社会和治理(Environmental, Social and Governance, ESG)是指从环境、社会和公司治理三个维度来评估企业经营的可持续性与对社会价值观念的影响。随着可持续发展与生态文明的理念逐渐成为共识,ESG也成为实践和研究的热点。ESG关注环境和可持续发展,但当前ESG研究与生态环境科学的结合明显不足。简要回顾了中国的ESG实践,并将其自2005年起分为起步阶段(2005—2009年)、发展阶段(2010—2017年)和全面深化阶段(2018年至今)。通过对主流的ESG评价指标体系与联合国可持续发展目标的关系进行分析,发现二者高度相符,表明ESG与生态环境科学联系密切。根据国内外ESG研究文献的CiteSpace分析,发现现有研究多围绕上市公司和金融机构展开,研究者主要来自金融、经济、社会、管理乃至商务等领域,当前ESG研究与生态环境科学存在脱节,总体上与生态环境科学的结合还有待发展和深入。在此基础上,文章指出应尽快推进ESG研究与生态环境科学的结合,并对未来如何开展相关实践与研究进行了展望,以期为生态环境领域学者开展ESG研究提供参考。

Abstract :

由水库建设引起的河流湖库化和富营养化,是全球普遍面临的重大生态环境问题.而内源污染负荷过大会加剧水库富营养化和水质恶化的风险.因缺乏亚热带河道型水库沉积物中内源磷污染解析,本文采用薄膜扩散梯度(DGT)和高分辨率渗析技术(HR-Peeper)以原位、高分辨率技术对河道型深水水库闽江水口水库中磷(P)、铁(Fe)、锰(Mn)、硫(S)进行监测,并研究河道型水库P-Fe-Mn-S的地球化学耦合机制以及磷的赋存形态和迁移释放机制.结果表明:氢氧化钠提取磷(NaOH-P)是沉积物中磷形态的主要形式,铁结合态磷是控制沉积物磷释放的关键因素,水口水库水体和沉积物营养化程度高,沉积物内源磷污染较严重;在垂直剖面上,沉积物中的P与Fe、Mn、S呈显著正相关,铁锰氧化物的还原溶解和硫酸盐还原有利于磷活化和释放;沉积物中P、Fe、Mn、S会形成正释放从而扩散到上覆水中,在水库开闸和泄洪期间,对流会暂时打破分层,内源磷的释放高于多数天然浅水湖库,这突出了河道型水库内源磷污染治理的重要性和紧迫性.
