| ○ | ○ | Article | Hydrothermally constructed AgWO4-rGO nanocomposites as an electrode enhancer for ultrasensitive electrochemical detection of hazardous herbicide crisquat | The advancements in electrode materials with high efficiency has been prioritized to effectively monitor the presence of harmful pesticides concerning the environment. In such a way, we hydrothermally constructed a hybrid AgWO4-rGO nanocomposites for the rapid electrochemical detection of crisquat (CQT). The structural, compositional, morphological and topographical characterization for AgW4-rGO nanocomposites is thoroughly performed to understand its electrocatalytic properties. The AgWO4-rGO nanocomposites are used as an electrode enhancer (rGO@AgWO4/GCE) for the electrochemical investigations towards CQT detection. The results indicated that the rGO@AgWO4/GCE possessed an excellent catalytic activity with a wide linear detection range 1-1108 mu M coupled with an ultrasensitive limit of detection (LOD) 0.0661 mu M for electrochemical CQT detection. The rGO@AgWO4/GCE CQT sensor also expressed remarkable sensitivity of 0.6306 mu A mu M- 1cm(-2 )in addition to good selectivity and reproducibility. Furthermore, the commercial CQT, river water, tap water and washed vegetable water are used as a representative for real world analysis using rGO@AgWO4/GCE and results are highly appreciable for the real time CQT detection. Our work proposes a novel hybrid rGO@AgWO4 nano composites reinforced electrodes for ultra-trace level CQT detection with good reliability and can be advocated for real time detection of pesticides. | Maheshwaran, Selvarasu; Renganathan, Vengudusamy; Chen, Shen-Ming; Balaji, Ramachandran; Kao, C.

| ○ | ○ | Article | In-situ Pt nanoparticles decorated BiOBr heterostructure for enhanced visible light-based photocatalytic activity: Synergistic effect | Advanced functional materials for photocatalytic hydrogen (H2) generation using abundant solar energy are the core of new and renewable energy research. In this paper, we report the in-situ deposition of platinum quantum sized particles (Pt QDs) on bismuth oxybromide (BBr) 3D marigold flowers with exposed (101)/(110) facets (i.e. BBr-Pt) hierarchies prepared by a simple solvo-thermal method acting as a surfactant/structure stabilizer in the presence of CTAB. Synthesized samples were characterized by a series of analytical techniques. Intimate contact as demonstrated by HRTEM, effect of Pt loading in 3D-BiOBr nanostructure on photocatalytic H-2 production and crystal violet (CV) dye degradation rate under white LED light irradiation was studied. This was greatly improved by loading Pt QDs on BBr, the latter showing the highest photocatalytic activity for BBr-2Pt nanostructure, due to the synergistic effect of quantum-sized Pt nanoparticles and exposed ((101) and (110) planes). The BBr-2Pt nanostructure photocatalysts showed highest H-2 generation of 320.69 mu mol g(-1,) which is 142 folds larger than bare BBr (2.26 mu mol g(-1)). | Devarayapalli, Kamakshaiah Charyulu; Zeng, Jie; Lee, Dae Sung; Vattikuti, S.

| ○ | ○ | Article | Integrated biorefinery approach to valorize citrus waste: A sustainable solution for resource recovery and environmental management | Citrus fruits are extensively cultivated, consumed and major processed horticulture crops around the globe. High processing and consumption generate huge quantities of solid organic wastes. Citrus waste represents approximately 40-50% of total fruit weight, which consists of rag (membranes and cores), pulp, seeds, and peel (albedo and flavedo), which are a potential source of value-added products including essential oils, carotenoids, pectin, dietary fibers, and polyphenols biofuel, etc. However, waste produced is discarded as waste in the environment, which causes a serious threat due to the presence of bioactive compounds. Recent research strategies on the integrated biorefinery approach explore various ways to utilize the waste obtained from the citrus wastes for their subsequent recovery of value-added products. Moreover, the citrus waste can be turned into various bioproducts, viz., enzymes, biofuels, and biopolymers using the integrated biorefinery approach, which can optimize the development of green waste for sustainability and economic benefits. Given the sustainable solution for resource recovery and environmental management, the article reviews the latest advances in the novel valorization approach and valuation of the existing state-of-the-art green technologies for citrus waste utilization to bring a sustainable solution for increasing demand for food, fuel, and energy security. To achieve the zero-waste approach and industrial viability, more efforts should be given to scale-up green recovery techniques along with diverse product profiling. | Yadav, Vivek; Sarker, Aniruddha; Yadav, Ashish; Miftah, Amilin Oktarajifa; Bilal, Muhammad; Iqbal, Hafiz M.

| ○ | ○ | Article | Melatonin and nitric oxide: Dual players inhibiting hazardous metal toxicity in soybean plants via molecular and antioxidant signaling cascades | Melatonin (MT), a ubiquitous signaling molecule, is known to improve plant growth. Its regulatory function alongside nitric oxide (NO) is known to induce heavy metal (Cd and Pb) stress tolerance, although the underlying mechanisms remain unknown. Here, we observed that the combined application of MT and NO remarkably enhanced plant biomass by reducing oxidative stress. Both MT and NO minimized metal toxicity by significantly lowering the levels of endogenous abscisic acid and jasmonic acid via downregulating NCED3 and upregulating catabolic genes (CYP707A1 and CYP707A2). MT/NO-induced mitigation of Cd and Pb stress was associated with increased endo-melatonin and variable endo-S-nitrosothiol levels caused by enhanced expression of gmNR and gmGSNOR mRNAs. Remarkably, the combined application of MT/NO reduced soil Cd and Pb mobilization by increasing the uptake of Ca2+ and K+ and increasing the exudation of organic acids into the rhizosphere. These results correlated with the upregulation of MTF-1 and WARKY27 during metal translocation. MT/NO regulates the MAPK and CDPK cascades to promote plant cell survival and Ca2+ signaling, thereby imparting resistance to heavy metal toxicity. In conclusion, MT/NO modulates the stress-resistance machinery to mitigate Cd and Pb toxicity by regulating the activation of antioxidant and molecular transcription factors. | Imran, Muhammad; Khan, Abdul Latif; Mun, Bong-Gyu; Bilal, Saqib; Shaffique, Shifa; Kwon, Eun-Hae; Kang, Sang-Mo; Yun, Byung-Wook; Lee, In -Jung | Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea; Univ Nizwa, Nat & Med Sci Res Ctr, Nizwa 616, Oman; Univ Houston, Coll Technol, Dept Engn Technol, Sugar Land, TX 77479 USA | ; Khan, Abdul/B-1005-2010; Imran, Muhammad/AFL-6590-2022; Lee, In-Jung/GLS-0432-2022; Mun, BongGyu/GYD-6010-2022; Kang, Sang-Mo/MBG-7823-2025; shaffique, shifa/KUC-7102-2024 | 58282433800; 26639372800; 57147241300; 57031617400; 57203898867; 57224398710; 56189696900; 8245123600; 16425830900 | m.imran02@yahoo.com;bwyun@knu.ac.kr;ijlee@knu.ac.kr; | CHEMOSPHERE | CHEMOSPHERE | 0045-6535 | 1879-1298 | 308 | SCIE | ENVIRONMENTAL SCIENCES | 2022 | 8.8 | 10.7 | 2.91 | 2025-06-25 | 38 | 40 | Melatonin; Nitric oxide; Cd and Pb; Antioxidant; MAPKs and CDPKs cascades; Molecular transcription factors | CONFERS CHILLING TOLERANCE; SPHINGOMONAS SP LK11; OXIDATIVE STRESS; N-NITROSOMELATONIN; CADMIUM TOXICITY; GENE-EXPRESSION; DROUGHT-STRESS; HEAVY-METALS; MAP KINASE; RICE ROOTS | Antioxidant; Cd and Pb; MAPKs and CDPKs cascades; Melatonin; Molecular transcription factors; Nitric oxide | Abscisic Acid; Antioxidants; Cadmium; Lead; Melatonin; Metals, Heavy; Nitric Oxide; Plants; S-Nitrosothiols; Soil; Soybeans; Transcription Factors; Antioxidants; Cell signaling; Heavy metals; Hormones; Machinery; Plants (botany); Soils; Toxicity; Transcription; Transcription factors; abscisic acid; acetic acid; ascorbate peroxidase; cadmium; calcium dependent protein kinase; calcium ion; carboxylic acid; chlorophyll a; chlorophyll b; citric acid; complementary DNA; cyp707a1 protein; cyp707a2 protein; diazomethane; gmgsnor protein; gmnr protein; jasmonic acid; lactic acid; lead; malonaldehyde; melatonin; messenger RNA; mitogen activated protein kinase; mtf 1 protein; nced3 protein; nitric oxide; peroxidase; phytohormone; potassium ion; RNA; s nitrosothiol; superoxide dismutase; transcription factor; unclassified drug; warky27 protein; abscisic acid; antioxidant; cadmium; heavy metal; lead; melatonin; nitric oxide; s nitrosothiol; transcription factor; Ca 2+; Cd and pb; Cd stress; Hazardous metals; MAPK and CDPK cascade; Melatonin; Metal toxicity; Molecular transcription factor; Pb stress; Soybean plants; abscisic acid; antioxidant; biomass; exudation; heavy metal; mobilization; nitric oxide; signaling; soybean; toxicity; antioxidant activity; Article; biomass; calcium signaling; calcium transport; cell survival; chlorophyll content; controlled study; down regulation; gene expression; health hazard; heavy metal poisoning; molecular biology; nonhuman; oxidative stress; physiological stress; plant cell; plant growth; protein expression; real time polymerase chain reaction; rhizosphere; RNA extraction; signal transduction; soybean; upregulation; genetics; metabolism; plant; soil; soybean; Nitric oxide | English | 2022 | 2022-12 | 10.1016/j.chemosphere.2022.136575 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Microplastic-associated pathogens and antimicrobial resistance in environment | The ubiquitous use of microplastics and their release into the environment especially the water bodies by anthropogenic/industrial activities are the major resources for microplastic contamination. The widespread and often injudicious use of antimicrobial drugs or antibiotics in various sectors including human health and hygiene, agriculture, animal husbandry and food industries are leading to the release of antibiotics into the wastewater/ sewage and other water bodies, particularly in urban setups and thus leads to the antimicrobial resistance (AMR) in the microbes. Microplastics are emerging as the hubs as well as effective carriers of these microbial pathogens beside their AMR-genes (ARGs) in marine, freshwater, sewage/wastewater, and urban river ecosystems. These drug resistant bacteria interact with microplastics forming synthetic plastispheres, the ideal niche for biofilm formations which in turn facilitates the transfer of ARGs via horizontal gene transfer and further escalates the occurrence and levels of AMR. Microplastic-associated AMR is an emerging threat for human health and healthcare besides being a challenge for the research community for effective management/address of this menace. In this review, we encompass the increasing prevalence of microplastics in environment, emphasizing mainly on water environments, how they act as centers and vectors of microbial pathogens with their associated bacterial assemblage compositions and ultimately lead to AMR. It further discusses the mechanistic insights on how microplastics act as hosts of biofilms (creating the plastisphere). We have also presented the modern toolbox used for microplastic-biofilm analyses. A review on potential strategies for addressing microplastic-associated AMR is given with recent success stories, challenges and future prospects. | Kaur, Kawaljeet; Reddy, Sagar; Barathe, Pramod; Oak, Uttara; Shriram, Varsha; Kharat, Sanjay S.; Govarthanan, M.; Kumar, Vinay | Savitribai Phule Pune Univ, Modern Coll Arts Sci & Commerce, Dept Biotechnol, Pune 411016, Maharashtra, India; Savitribai Phule Pune Univ, Prof Ramkrishna More Coll, Dept Bot, Pune 411016, Maharashtra, India; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea | Reddy, Sagar/HHS-4817-2022; Govarthanan, Muthusamy/C-1491-2014; Kaur, Kawaljeet/ABA-6910-2021; Muthusamy, Govarthanan/C-1491-2014; Kumar, Vinay/P-1101-2017 | 57225456203; 57355584100; 57355153800; 57211556580; 20436406900; 6603286759; 54881927600; 7404634888 | gova.muthu@gmail.com;vinaymalik123@gmail.com; | CHEMOSPHERE | CHEMOSPHERE | 0045-6535 | 1879-1298 | 291 | SCIE | ENVIRONMENTAL SCIENCES | 2022 | 8.8 | 10.7 | 9.82 | 2025-06-25 | 122 | 136 | Microplastic; Antimicrobial resistance (AMR); Antimicrobial resistance genes; Biofilms; Horizontal gene transfer; Multidrug resistance; Microbial pathogens | WASTE-WATER; MARINE-ENVIRONMENT; PLASTIC DEBRIS; SURFACE WATERS; FRESH-WATER; POLLUTION; SEDIMENTS; BIOFILMS; BACTERIA; FATE | Antimicrobial resistance (AMR); Antimicrobial resistance genes; Biofilms; Horizontal gene transfer; Microbial pathogens; Microplastic; Multidrug resistance | Animals; Anti-Bacterial Agents; Anti-Infective Agents; Drug Resistance, Bacterial; Ecosystem; Humans; Microplastics; Plastics; Agriculture; Antibiotics; Bacteria; Controlled drug delivery; Ecosystems; Gene transfer; Genes; Health risks; Microplastic; Pathogens; RNA; Sewage; Targeted drug delivery; fresh water; glycoprotein; microplastic; polyamide; polyester; polypropylene; polysaccharide; polystyrene; virulence factor; antiinfective agent; plastic; Antimicrobial resistance; Antimicrobial resistance gene; Antimicrobial resistances; Horizontal gene transfer; Microbial pathogens; Microplastics; Multidrug resistance; Resistance genes; Waterbodies; animal husbandry; antibiotics; biofilm; drug; gene transfer; health care; pathogen; plastic; agriculture; animal husbandry; antibiotic resistance; aquatic environment; Article; biodegradation; biofilm; cell communication; chemical parameters; contamination; controlled study; dynamics; environment; flow cytometry; fluorescence in situ hybridization; food industry; Fourier transform infrared spectroscopy; genetic resistance; glycocalyx; health care; horizontal gene transfer; hydrophobicity; hygiene; infectious agent; management; marine environment; microflora; microplastic pollution; microscopy; multidrug resistance; nonhuman; obesity; pollution; prevalence; pyrolysis; quorum sensing; Raman spectrometry; scanning electron microscopy; sewage; soil analysis; thermogravimetry; waste water management; waste water treatment plant; wastewater; animal; antibiotic resistance; ecosystem; human; Biofilms | English | 2022 | 2022-03 | 10.1016/j.chemosphere.2021.133005 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | NMR-based metabolomic analysis of human plasma to examine the effect of exposure to persistent organic pollutants | Persistent organic pollutants (POPs) are lipophilic environmental toxins, and the level of chemicals accumulated in the body through the food chain has been linked to the incidence of diseases such as type 2 diabetes, car-diovascular disease, and cancer. We analyzed the concentration of POPs and circulating metabolites and investigated the associations between the concentration of plasma metabolites and the levels of polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) to determine the effect of the accumulation of POPs in human samples. Metabolic profiling of plasma from 276 Korean participants was performed using 1H nuclear magnetic resonance (NMR) and statistical analyses. The concentrations of PCBs and OCPs in each sample were measured. Correlation analysis and a covariate-adjusted general linear model (GLM) were used to investigate the association of the concentration of POPs with circulating metabolites in human blood samples. We found that four categories of E6PCBs and E5OCPs based on rank were significantly correlated with 4 and 5 metabolites, respectively, after adjusting for confounding factors, including age, sex, body mass index (BMI), smoking status, alcohol intake, physical activity, triglycerides, and total cholesterol. According to the GLM analyses, 3 metab-olites, namely, creatinine, acetate, and formate, among the 4 correlated metabolites were associated with four categories of rank-based E6PCBs. On the other hand, the quartiles of the rank-based E5OCPs were not associated with any circulating metabolites among the 5 correlated metabolites. Our findings indicate that the metabolites related to short-chain fatty acids and creatine can be useful risk indicators for estimating the effect of PCB exposure. | Jang, Seo Young; Jung, Youngae; Lee, Duk-Hee; Hwang, Geum-Sook | Korea Basic Sci Inst, Western Seoul Ctr, Integrated Metabol Res Grp, Seoul 03759, South Korea; Ewha Womans Univ, Dept Chem & Nano Sci, Seoul 03760, South Korea; Kyungpook Natl Univ, Sch Med, Dept Prevent Med, Daegu 41566, South Korea | ; Hwang, GeumSook/NQF-0921-2025 | 57201467899; 37074684200; 57211851121; 7202676099 | gshwang@kbsi.re.kr; | CHEMOSPHERE | CHEMOSPHERE | 0045-6535 | 1879-1298 | 307 | SCIE | ENVIRONMENTAL SCIENCES | 2022 | 8.8 | 10.7 | 0.29 | 2025-06-25 | 4 | 4 | Persistent organic pollutants (POPs); Polychlorinated biphenyls (PCBs); Organochlorine pesticides (OCPs); Metabolomics; Human plasma | GUT MICROBIOTA; ADIPOSE-TISSUE; BREAST-CANCER; HUMAN-SERUM; ASSOCIATION; OBESITY; BIOMARKERS; ACETATE; IMPACT; MICE | Human plasma; Metabolomics; Organochlorine pesticides (OCPs); Persistent organic pollutants (POPs); Polychlorinated biphenyls (PCBs) | Cholesterol; Creatine; Creatinine; Diabetes Mellitus, Type 2; Environmental Pollutants; Formates; Humans; Hydrocarbons, Chlorinated; Magnetic Resonance Spectroscopy; Persistent Organic Pollutants; Pesticides; Polychlorinated Biphenyls; Triglycerides; Biomolecules; Chemical contamination; Diseases; Fatty acids; Metabolites; Nuclear magnetic resonance; Pesticides; Plasma (human); Polychlorinated biphenyls; Risk perception; chlorinated hydrocarbon; cholesterol; creatine; creatinine; formic acid; pesticide; polychlorinated biphenyl; triacylglycerol; Environmental toxins; Food chain; Human plasmas; Metabolomic analysis; Metabolomics; Organochlorine pesticide; Organochlorine pesticides; Persistent organic pollutant; Polychlorinated biphenyl; Type-2 diabetes; accumulation; alcohol; body mass; food chain; nuclear magnetic resonance; PCB; persistent organic pollutant; plasma; pollution exposure; smoking; human; non insulin dependent diabetes mellitus; nuclear magnetic resonance spectroscopy; pollutant; Organic pollutants | English | 2022 | 2022-11 | 10.1016/j.chemosphere.2022.135963 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Polymeric biomolecules based nanomaterials: Production strategies and pollutant mitigation as an emerging tool for environmental application | The ever-exploding global population coupled with its anthropogenic impact has imparted unparalleled detri-mental effects on the environment and mitigating them has emerged as the prime challenge and focus of the current century. The niche of nanotechnology empowered by composites of biopolymers in the handling of xenobiotics and environmental clean-up has an unlimited scope. The appositeness of biopolymer-nanoparticles (Bp-NPs) for environmental contaminant mitigation has received unique consideration due to its exclusive combination of physicochemical characteristics and other attributes. The current review furnishes exhaustive scrutiny of the current accomplishments in the development of Bp-NPs and biopolymer nanomaterials (Bp-NMs) from various polymeric biomolecules.

| ○ | ○ | Article | Reduction of antibiotic resistome in influent of a wastewater treatment plant (WWTP) via a chemically enhanced primary treatment (CEPT) process | Chemically enhanced primary treatment (CEPT) has been considered for maximizing wastewater energy re-covery by enhancing the carbon captured through the primary treatment. However, evaluating the potential of CEPT as a primary treatment process for removing antibiotic resistance genes (ARGs) in the influent from a wastewater treatment plant (WWTP) has seldom been investigated. In this study, CEPT was conducted to assess simultaneous reduction of 13 major targeted ARGs and common pollutants in wastewater compared with pri-mary sedimentation alone (non-CEPT). CEPT processes using three types of coagulants (PACl, FeCl3 and alum) effectively reduced absolute abundance of ARGs and intI1 in the influent from municipal WWTP. Average log-removal of absolute abundance of ARGs was achieved up to 1.77 +/- 0.41 along with 90% turbidity reduction compared to non-CEPT. Through the simultaneous reduction of ARGs and intI1 genes during a CEPT process, ARGs proliferation may be limited directly through reduction of antibiotic resistant bacteria or indirectly through decreasing the possibility of horizontal gene transfer by intI1 removal. Reduction of ARGs and intI1 was improved by increasing coagulants' doses: abundances of residual ARGs under optimal dose conditions were similar, regardless of the different characteristics of coagulant types. The strongly positive correlation between reduction of turbidity/total phosphorus (T-P) and ARGs was explored, identifying that turbidity or T-P might be suitable indicators linked with variations in the abundance of ARGs during CEPT. As a result, CEPT may prove promising in efforts to control ARGs flowing into a WWTP. | Shin, Jingyeong; Choi, Sangki; Park, Chang Min; Wang, Jinhua; Kim, Young Mo | Hanyang Univ, Dept Civil & Environm Engn, Seoul 04763, South Korea; Gwangju Inst Sci & Technol, Sch Earth Sci & Environm Engn, Gwangju 61005, South Korea; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Shandong Agr Univ, Key Lab Agr Environm Univ Shandong, Coll Resources & Environm, Tai An 271018, Shandong, Peoples R China | Kim, Young Mo/HKF-1374-2023; Park, Chang Min/CAA-8506-2022 | 57194702841; 57195286868; 57209588953; 55929379800; 57202258703 | wjh@sdau.edu.cn;youngmo@hanyang.ac.kr; | CHEMOSPHERE | CHEMOSPHERE | 0045-6535 | 1879-1298 | 286 | SCIE | ENVIRONMENTAL SCIENCES | 2022 | 8.8 | 10.7 | 1.75 | 2025-06-25 | 25 | 24 | Chemically enhanced primary treatment (CEPT); Antibiotic resistance genes (ARGs); intI1; Wastewater treatment plant (WWTP); Influent; Coagulants | RESISTANCE GENES; TREATMENT SYSTEMS; TREATMENT SLUDGE; REMOVAL; BACTERIA; FEEDLOTS; SOILS; FATE | Antibiotic resistance genes (ARGs); Chemically enhanced primary treatment (CEPT); Coagulants; Influent; intI1; Wastewater treatment plant (WWTP) | Anti-Bacterial Agents; Drug Resistance, Microbial; Genes, Bacterial; Waste Water; Water Purification; Chlorine compounds; Coagulation; Gene transfer; Genes; Iron compounds; Reclamation; Sewage pumping plants; Turbidity; Wastewater treatment; Water treatment plants; aluminum potassium sulfate; coagulating agent; ferric chloride; phosphorus; poly aluminum chloride; unclassified drug; antiinfective agent; % reductions; Antibiotic resistance gene; Antibiotic resistance genes; Chemically enhanced primary treatment; Influent; Inti1; Treatment process; Waste water treatment plants; Wastewater treatment plant; antibiotic resistance; antibiotics; detection method; gene expression; gene transfer; phosphorus; sedimentation; turbidite; turbidity; wastewater treatment; wastewater treatment plant; aac(6')lb cr gene; antibiotic resistance; antibiotic resistome; Article; bacterial gene; bla ctx gene; bla shv gene; bla tem gene; chemically enhanced primary treatment; controlled study; ermb gene; ermc gene; flor gene; horizontal gene transfer; inti1 gene; nonhuman; physical chemistry; qnrd gene; qnrs gene; sedimentation; sul1 gene; sul2 gene; teta gene; tetb gene; tetd gene; tete gene; tetg gene; teth gene; tetm gene; tetp gene; tetq gene; tetx gene; tetz gene; turbidity; waste water management; waste water treatment plant; genetics; wastewater; water management; Antibiotics | English | 2022 | 2022-01 | 10.1016/j.chemosphere.2021.131569 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Review | Remediation of pharmaceutical pollutants using graphene-based materials-A review on operating conditions, mechanism and toxicology | Graphene is a high surface area special carbon compound with exceptional biological, electronic and mechanical properties. Graphene-based materials are potential components used in water treatment on different modes and processes. Ibuprofen and ciprofloxacin are two commonly found pharmaceutical contaminants discharged into water bodies from industrial, domestic and hospital sources. Their concentration levels in water bodies are reported in the range of 1 mu g/L to 6.5 mg/L and 0.050-100 mu g/L respectively. Their toxic effects pose very high risk to the inhabiting organisms. Their ability to resist biodegradation and capacity to bioaccumulate makes the conventional methods less effective in removal. In the present article, treatment of these compounds via three methods, adsorption, photocatalytic degradation and electro-fenton reactions using graphene-based materials along with the methods adopted for synthesis and treatment are reviewed. The uptakes obtained by graphenederived adsorbents are presented along with the optimal operating conditions. Studies reported complete removal of ibuprofen from wastewater was achieved at 7 pH for 60 min using graphene membrane as adsorbent and uptake of 99% of ciprofloxacin was exhibited for graphene nanoplates/boron nitrate aerogel at a pH of 7 and 60 min. The reduced graphene oxide surface exhibits higher affinity to light adsorption which leads to the formation of photo generated electrons. The future perspectives for improved applications of graphene-based materials and the research gap currently existing are highlighted. | Akash, S.; Sivaprakash, Baskaran; Rajamohan, Natarajan; Govarthanan, Muthusamy; Elakiya, B.

| ○ | ○ | Review | Review of adsorption-membrane hybrid systems for water and wastewater treatment | Adsorption is an effective method for the removal of inorganic and organic contaminants and has been commonly used as a pretreatment method to improve contaminant removal and control flux during membrane filtration. Over the last two decades, many researchers have reported the use of hybrid systems comprising various adsorbents and different types of membranes, such as nanofiltration (NF), ultrafiltration (UF), and microfiltration (MF) membranes, to remove contaminants from water. However, a comprehensive evaluation of the removal mechanisms and effects of the operating conditions on the transport of contaminants through hybrid systems comprising various adsorbents and NF, UF, or MF membranes has not been performed to date. Therefore, a systematic review of contaminant removal using adsorption-membrane hybrid systems is critical, because the transport of inorganic and organic contaminants via the hybrid systems is considerably affected by the contaminant properties, water quality parameters, and adsorbent/membrane physicochemical properties. Herein, we provide a comprehensive summary of the most recent studies on adsorption-NF/UF/MF membrane systems using various adsorbents and membranes for contaminant removal from water and wastewater and highlight the future research directions to address the current knowledge gap. | Kim, Sewoon; Nam, Seong-Nam; Jang, Am; Jang, Min; Park, Chang Min; Son, Ahjeong; Her, Namguk; Heo, Jiyong; Yoon, Yeomin | Univ South Carolina, Dept Civil & Environm Engn, 300 Main St, Columbia, SC 29208 USA; Korea Army Acad Yeong Cheon, Dept Civil & Environm Engn, 495 Hogook Ro, Gyeongbuk 38900, South Korea; Sungkyunkwan Univ, Sch Civil & Architecture Engn, 2066 Seobu Ro, Suwon 440746, South Korea; Kwangwoon Univ, Dept Environm Engn, 447-1 Wolgye Dong, Seoul, South Korea; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Ewha Womans Univ, Dept Environm Sci & Engn, 52 Ewhayeodae Gil, Seoul 03760, South Korea | Yoon, Yeomin/KDP-2253-2024; Jang, Min/J-2230-2012; Nam, Seong-Nam/ABT-9415-2022; Park, Chang Min/CAA-8506-2022; Son, Ahjeong/AAV-7000-2021; Jang, Min/M-6690-2018 | 57201422323; 57226757907; 7004582729; 36762550700; 57209588953; 23487252600; 6701721727; 42461338400; 7402126688 | jiyongheo@naver.com;yoony@cec.sc.edu; | CHEMOSPHERE | CHEMOSPHERE | 0045-6535 | 1879-1298 | 286 | SCIE | ENVIRONMENTAL SCIENCES | 2022 | 8.8 | 10.7 | 3.99 | 2025-06-25 | 131 | 140 | Membrane; Adsorption; Hybrid system; Water treatment; Wastewater treatment | NATURAL ORGANIC-MATTER; POWDERED ACTIVATED CARBON; ULTRAFILTRATION MEMBRANE; HEAVY-METALS; HUMIC-ACID; CONCENTRATION POLARIZATION; NANOFILTRATION MEMBRANES; MICROFILTRATION PROCESS; AROMATIC-HYDROCARBONS; CERAMIC MEMBRANE | Adsorption; Hybrid system; Membrane; Wastewater treatment; Water treatment | Adsorption; Membranes, Artificial; Ultrafiltration; Waste Water; Water Purification; Adsorption; Contamination; Hybrid systems; Membranes; Microfiltration; Physicochemical properties; Water filtration; Water quality; Adsorption membranes; Contaminant control; Contaminant removal; Inorganic contaminants; Micro-filtration membranes; Organic contaminant; Pretreatment methods; Ultra-filtration membranes; Ultrafiltration membranes; Water and wastewater treatments; adsorption; detection method; nanofossil; operations technology; pollutant removal; ultrafiltration; wastewater treatment; water quality; adsorption; artificial membrane; ultrafiltration; wastewater; water management; Wastewater treatment | English | 2022 | 2022-01 | 10.1016/j.chemosphere.2021.131916 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Simultaneous removal of heavy metal ions using carbon dots-doped hydrogel particles | Heavy metal ions (HMI) have attracted worldwide concern due to their serious environmental pollution which led to the risk of health conditions. From Red Malus floribunda fruits, nitrogen-doped carbon dots (N-CDs) were prepared, followed by hybrid-spherical shaped hydrogel particles (CGCDs) were prepared. The prepared CGCDs were utilized as adsorbents for HMI-(Hg(II), Cd(II), Pb(II), and Cr(III)) from water. N-CDs with about 4.0 nm in diameter were characterized by various techniques such as field emission-scanning electron microscopy (FESEM) and attenuated total reflection-fourier transform infrared spectroscopy (ATR-FTIR) that confirm the presence of nitrogen, oxygen, and carbon functionalities. The prepared spherical CGCDs were characterized very well before it was used as HMI adsorbents. The sizes of the CGCDs were ranges between 20 and 300 mu m and the degree of swelling was calculated as 1320 %. ATR-FTIR and X-ray diffraction analyses reveal the presence of N CDs in CGCDs. Further, FE-SEM confirms the spherical shape morphology of CGCDs. Three different concentrations of HMI solutions were 500 mg/L, 1000 mg/L, and 1500 mg/L. Hg(II) adsorbed proficiently by CGCDs in single metal ion systems with similar to 72 % and almost complete removal of Hg(II) ions (99 %) in multiple metal ion systems was observed. Moreover, all metal ions Hg(II), Cd(II), Pb(II), and Cr(III) were efficiently (>70 %) removed in multiple systems by CGCDs. After HMI adsorption experiments, the elemental mapping from FE-SEM and X-ray photoelectron spectroscopy studies conveys the presence of HMI on CGCDs. This suggests that CGCDs would be a suitable adsorbent for the simultaneous removal of multiple HMI from wastewater. | Perumal, Suguna; Atchudan, Raji; Thirukumaran, Periyasamy; Yoon, Dong Ho; Lee, Yong Rok; Cheong, In Woo | Kyungpook Natl Univ, Sch Engn, Dept Appl Chem, Daehak Ro 80, Daegu 41566, South Korea; Yeungnarn Univ, Sch Chem Engn, Gyongsan 38541, South Korea; Kuk Il Paper Mfg Co Ltd, R&D Ctr, Yongin 17128, South Korea | perumal, suguna/N-9075-2017; Lee, Yong/K-6373-2015; RAJI, ATCHUDAN/C-9904-2017 | 56673798900; 26648054700; 56548971100; 57205212303; 57330662900; 7006733373 | yrlee@yu.ac.kr;inwoo@knu.ac.kr; | CHEMOSPHERE | CHEMOSPHERE | 0045-6535 | 1879-1298 | 286 | SCIE | ENVIRONMENTAL SCIENCES | 2022 | 8.8 | 10.7 | 4.8 | 2025-06-25 | 57 | 68 | Heavy metals ions; Carbon dots; Multiple metal ions adsorption; Hydrogel particles; Aqueous system | WASTE-WATER TREATMENT; QUANTUM DOTS; FACILE SYNTHESIS; FLUORESCENT-PROBE; GREEN SYNTHESIS; ADSORPTION; CHITOSAN; CELLULOSE; CD(II); HG(II) | Aqueous system; Carbon dots; Heavy metals ions; Hydrogel particles; Multiple metal ions adsorption | Adsorption; Cadmium Compounds; Carbon; Chromium Compounds; Esca; Lead Compounds; Mercury Compounds; X Ray Spectroscopy; Adsorption; Carbon; Hydrogels; Ions; Metals, Heavy; Waste Water; Water Pollutants, Chemical; Malus floribunda; Adsorption; Cadmium compounds; Carbon; Chromium compounds; Doping (additives); Enamels; Field emission microscopes; Fourier transform infrared spectroscopy; Lead compounds; Mercury (metal); Mercury compounds; Metal ions; Nitrogen; Scanning electron microscopy; Spheres; X ray diffraction analysis; X ray photoelectron spectroscopy; carbon; heavy metal; ion; Aqueous system; Attenuated total reflection fouriertransform infrared spectroscopy (ATR/FT-IR); Carbon dots; Field emission scanning electron microscopy; Heavy metal ion; Hydrogel particles; Metals ions; Multiple metal ion adsorption; Nitrogen-doped carbons; Simultaneous removal; adsorption; carbon nanotube; detection method; heavy metal; pollutant removal; wastewater; wastewater treatment; adsorption; hydrogel; wastewater; water pollutant; Hydrogels | English | 2022 | 2022-01 | 10.1016/j.chemosphere.2021.131760 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Stability analysis for delayed Cohen-Grossberg Clifford-valued neutral-type neural networks | The aim of this study is to explore the global stability of Cohen-Grossberg Clifford-valued neutral-type neural network models with time delays. In order to achieve the aim of this paper, and to solve the non-commutativity problem caused by Clifford numbers multiplication, the original Clifford-valued system is first decomposed into 2(m) n-dimensional real-valued systems. Some sufficient criteria for the global stability of the addressed network models are established by constructing an appropriate Lyapunov functional. The established stability conditions have not been affected by the neutral delay and time delay values. The proposed method and results of this paper are new. The feasibility of the stability criteria obtained are verified using two numerical examples. | Sriraman, Ramalingam; Rajchakit, Grienggrai; Kwon, Oh-Min; Lee, Sang-Moon | Kalasalingam Acad Res & Educ, Dept Math, Srivilliputhur, India; Maejo Univ, Fac Sci, Dept Math, Chiang Mai, Thailand; Chungbuk Natl Univ, Sch Elect Engn, Cheongju 28644, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea | Rajchakit, Grienggrai/K-7043-2014; Lee, Sangmoon/C-4502-2018; Ramalingam, Sriraman/HLX-0444-2023; Kwon, O.M./AAB-4260-2019; Lee, Sang/E-4151-2012; Sriraman, R./AAZ-2439-2021 | 57159720700; 57201986186; 55444931800; 59510733500 | madwind@chungbuk.ac.kr; | MATHEMATICAL METHODS IN THE APPLIED SCIENCES | MATH METHOD APPL SCI | 0170-4214 | 1099-1476 | 45 | 17 | SCIE | MATHEMATICS, APPLIED | 2022 | 2.9 | 10.7 | 2.46 | 2025-06-25 | 13 | 14 | Clifford-valued neural network; Cohen-Grossberg neural network; Lyapunov functional; neutral delays; stability | GLOBAL EXPONENTIAL STABILITY; DISCRETE; CRITERIA; MEMORY | Clifford-valued neural network; Cohen–Grossberg neural network; Lyapunov functional; neutral delays; stability | Stability criteria; Time delay; ClIFFORD; Clifford-valued neural network; Cohen-Grossberg neural networks; Global stability; Lyapunov functionals; Neural network model; Neural-networks; Neutral delays; Neutral-type neural networks; Stability analyze; Lyapunov functions | English | 2022 | 2022-11-30 | 10.1002/mma.8426 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Synthesis of enhanced corrosion resistant Fe-B-C-Ti amorphous ribbons and evaluation of their photodegradation efficiency under light irradiation | Fe-based amorphous alloys have been found to be very efficient in the degradation of water pollutants due to their unique atomic arrangements with long-range disordered structure. In this work, Fe-B-C-Ti amorphous ribbons were successfully synthesized and showed high catalytic efficiency in the degradation of methylene blue (MB) under simulated sunlight and across a wide pH range. The catalytic efficiency was evaluated under different conditions to optimize the degradation performance. The amorphous ribbon Fe75B10C10Ti5 was found to exhibit the highest photocatalytic activity as explained by its optical and photoelectrochemical properties. It can degrade MB completely with low Fe-leaching and significant recyclability at pH close to a neutral range (pH 5). The degradation mechanisms can be explained in terms of photocatalytic activity along with the galvanic cell effect which contributed to the efficient MB degradation. This work provides a comprehensive idea for the synthesis of amorphous alloys by optimizing their elemental composition and also explains the catalytic activity of partially crystallized regions on the ribbon surface. The significant corrosion resistance and the quick degradation of MB in a wide pH range in a recyclable manner by these easily separable and highly efficient catalysts indicate great potential for their practical application. | Zuo, Mingqing; Moztahida, Mokrema; Lee, Dae Sung; Yi, Seonghoon | Kyungpook Natl Univ, Dept Mat Sci & Met Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea | ; Zuo, Mingqing/KSZ-8653-2024; Yi, Seonghoon/HGC-6912-2022 | 57192670037; 57202904382; 55568524907; 14008383000 | daesung@knu.ac.kr;yish@knu.ac.kr; | CHEMOSPHERE | CHEMOSPHERE | 0045-6535 | 1879-1298 | 287 | SCIE | ENVIRONMENTAL SCIENCES | 2022 | 8.8 | 10.7 | 0.29 | 2025-06-25 | 5 | 4 | Amorphous materials; Heterogeneous; Fenton-like reaction; Photodegradation; Corrosion resistance | BULK METALLIC GLASSES; SOLAR DISINFECTION; DRINKING-WATER; DEGRADATION; ALLOYS; DYE; PHOTOCATALYSTS; PERFORMANCE; REACTIVITY; CATALYST | Amorphous materials; Corrosion resistance; Fenton-like reaction; Heterogeneous; Photodegradation | Catalysis; Corrosion; Photolysis; Titanium; Aromatic compounds; Catalyst activity; Efficiency; Iron alloys; Oxidation; pH; Photocatalytic activity; Photodegradation; Water pollution; alloy; boron; carbon; hydrogen peroxide; iron; methylene blue; titanium; titanium carbide; Amorphous ribbon; Catalytic efficiencies; Corrosion-resistant; Fenton-like reactions; Heterogeneous; Light irradiations; Methylene Blue; Photo degradation; Photodegradation efficiency; Wide pH range; catalysis; catalyst; concentration (composition); degradation; detection method; inorganic compound; photodegradation; Article; catalytic efficiency; corrosion; crystallization; current density; Fenton reaction; irradiation; oxidation reduction reaction; pH; photocatalysis; photodegradation; photoluminescence; polarization; reaction analysis; solar radiation; surface property; synthesis; waste water management; catalysis; corrosion; photolysis; Corrosion resistance | English | 2022 | 2022-01 | 10.1016/j.chemosphere.2021.132175 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Tetracycline bioremediation using the novel Serratia marcescens strain WW1 isolated from a wastewater treatment plant | Tetracycline pollution is an emerging threat in aquatic and terrestrial environments because of its widespread applications in human disease, livestock, and aquaculture. Present study, investigated the tetracycline degrading novel Serratia marcescens strain WW1, which was isolated from a wastewater treatment plant (WWTP). Toxicity analysis of tetracycline with strain WW1 indicates that its intermediate metabolites are not toxic for the indicator bacteria and algae. The degradation conditions for the tetracycline optimized using response surface methodology (RSM) were determined as: pH 6.0; temperature, 36 ?; tetracycline concentration, 20 mg L-1; and inoculum size, 100 mu L (OD-0.5). The strain WW1 was able to utilize tetracycline during the growth phase, and it degraded 89.5% of the tetracycline within 48 h. The degradation kinetics suggested the strain perform significant tetracycline removal with half-life (t(1/2)) 239.04 and 12.44 h in control and treatments. Tetracycline and its intermediates were analyzed using High Performance Liquid Chromatography (HPLC) and Liquid Chromatography-Mass Spectroscopy (LC-MS). It was observed that strain WW1 could efficiently metabolize the tetracycline within 48 h of experiment. The ability of strain WW1 to degrade tetracycline justifies its use as an environmentally-useful bacterium. Therefore, the present study demonstrated that the degradation of antibiotics is possible using indigenous microbial strains. | Bhatt, Pankaj; Jeon, Chang-Hyun; Kim, Woong | Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea | ; Bhatt, Pankaj/AAF-1027-2020 | 57193623387; 57217491155; 55581636400 | pankajbhatt.bhatt472@gmail.com;elshine@knu.ac.kr; | CHEMOSPHERE | CHEMOSPHERE | 0045-6535 | 1879-1298 | 298 | SCIE | ENVIRONMENTAL SCIENCES | 2022 | 8.8 | 10.7 | 3.05 | 2025-06-25 | 45 | 45 | Tetracycline; Serratia sp. strain WW1; Wastewater; Treatment; Kinetics | VETERINARY ANTIBIOTICS; MICROBIAL COMMUNITY; DEGRADATION; OPTIMIZATION; RESISTANCE; POLLUTANT; BACTERIUM; TOXICITY; MANURE; SOIL | Kinetics; Serratia sp. strain WW1; Tetracycline; Treatment; Wastewater | Anti-Bacterial Agents; Biodegradation, Environmental; Humans; Serratia marcescens; Tetracycline; Water Purification; Agriculture; Bacteria; Biodegradation; Bioremediation; Degradation; Growth kinetics; High performance liquid chromatography; Mass spectrometry; Metabolites; Reclamation; Sewage pumping plants; Toxicity; Wastewater treatment; Water treatment plants; tetracycline; antiinfective agent; tetracycline; Aquatic environments; Human disease; Intermediate metabolites; Serratia; Serratia marcescens; Serratia sp.; Strain WW1; Terrestrial environments; Treatment; Waste water treatment plants; antibiotics; bioremediation; environmental degradation; kinetics; liquid chromatography; mass spectrometry; response surface methodology; wastewater treatment plant; Article; bacterial strain; bacterium isolate; bioremediation; concentration (parameter); controlled study; degradation kinetics; drug degradation; drug transformation; ecotoxicity; liquid chromatography-mass spectrometry; nonhuman; pH; phylogeny; response surface method; scanning electron microscopy; Serratia marcescens; signal noise ratio; waste water treatment plant; water temperature; bioremediation; human; metabolism; water management; Strain | English | 2022 | 2022-07 | 10.1016/j.chemosphere.2022.134344 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Unsupervised moving object segmentation using background subtraction and optimal adversarial noise sample search | Moving Objects Segmentation (MOS) is a fundamental task in many computer vision applications such as human activity analysis, visual object tracking, content based video search, traffic monitoring, surveillance, and security. MOS becomes challenging due to abrupt illumination variations, dynamic backgrounds, camouflage and scenes with bootstrapping. To address these challenges we propose a MOS algorithm exploiting multiple adversarial regularizations including conventional as well as least squares losses. More specifically, our model is trained on scene background images with the help of cross-entropy loss, least squares adversarial loss and l(1) loss in image space working jointly to learn the dynamic background changes. During testing, our proposed method aims to generate test image background scenes by searching optimal noise samples using joint minimization of l(1) loss in image space, l(1) loss in feature space, and discriminator least squares loss. These loss functions force the generator to synthesize dynamic backgrounds similar to the test sequences which upon subtraction results in moving objects segmentation. Experimental evaluations on five benchmark datasets have shown excellent performance of the proposed algorithm compared to the twenty one existing state-of-the-art methods. (C) 2022 Elsevier Ltd.
