| ○ | ○ | Article | Challenges and opportunities in the application of bioinspired engineered nanomaterials for the recovery of metal ions from mining industry wastewater | Heavy-metal-bearing wastewater is among the most formidable challenges the mining industry currently faces in maintaining its social license to operate. Amongst the technologies available for metal ion adsorption, bio-inspired engineering nanomaterials have emerged as one which exhibits great promise. However, current pro-cesses used for the preparation of adsorbents (including nanoscale activated carbon and biochar) represent a source of adverse impacts on the environment. In contrast, the application of biogenic-nanoparticles, i.e., those derived from processes catalysed by microbiota, has received significant attention in the last few years. Coupled with this, the use of naturally occurring reagents is of major importance for the sustainability of this emerging industry. This paper analyses the life cycle assessment (LCA) of the synthesis of adsorbents derived from agricultural wastes. Moreover, rather than simply recovering the ecotoxic metals from wastewater, the potential to valorise dissolved metals into high-value metallic nanoparticle products is discussed. LCA analysis revealed that the adsorbent had some adverse impact on the environment. The agricultural wastes contributed 27.86% to global warming, 54.64% to ozone formation, 33.06% to fine particles, and 98.24% to marine eutrophication. Mining wastewater is an important, and largely currently unexploited, source of metal value. However, the often -low concentration of such metals dictates that their conversion into high-value products (such as engineered nanoparticles) is an important new research frontier. Within this the use of biosynthesis methods has emerged as having great potential due to a range of beneficial attributes, including low cost, high efficacy and/or envi-ronmental compatibility. | Noman, Efaq Ali; Al-Gheethi, Adel; Al-Sahari, Mohammed; Mohamed, Radin Maya Saphira Radin; Crane, Rich; Aziz, Nur Adila Ab; Govarthanan, Muthusamy | Univ Tun Hussein Onn Malaysia, Fac Civil Engn & Build Environm, Dept Civil Engn, Parit Raja, Batu Pahat 86400, Johor, Malaysia; Univ Tun Hussein Onn Malaysia, Inst Integrated Engn, Micropollutant Res Ctr MPRC, Parit Raja, Batu Pahat 86400, Johor, Malaysia; Univ Exeter, Coll Engn Math & Phys Sci, Camborne Sch Mines, Penryn TR10, Cornwall, England; Kyungpook Natl Univ, Dept Environm Engn, Daegu, South Korea; Saveetha Dent Coll & Hosp, Saveetha Inst Med & Tech Sci, Dept Biomat, Chennai 600077, India | Mohammed, Efaq Ali Noman/U-6324-2018; mohamed, mostafa/AFE-7371-2022; aziz, atiqah/GXZ-8036-2022; Muthusamy, Govarthanan/C-1491-2014; Al-Sahari, Mohammed/AAC-9826-2020; Acworth, Richard/A-2017-2009; Al-Gheethi, Eur.

| ○ | ○ | Article | Detoxification of coir pith through refined vermicomposting engaging Eudrilus eugeniae | Hazardous coir industrial waste, coir pith has been subjected to 50 days vermicomposting with Eudrilus eugeniae by amending nitrogenous legume plant, Gliricidia sepium together with cattle dung in different combinations, after 21 days precomposting using Pleurotus sajor-caju spawn. An increase in electrical conductivity, total NPK and calcium, and a decrease in organic matter, total organic carbon, C/N ratio, C/P ratio and total phenolic content in the final vermicompost were observed. Dehydrogenase, urease and cellulase activity peaked up to 30 days of vermicomposting and then declined. The phytotoxicity studies with Brassica juncea, C/N ratio and enzyme activities confirmed the stability and maturity of vermicompost. The results also demonstrated that the 2:3:1 ratio (coir pith + Gliricidia sepium + cow dung) is a suitable effective combination for nutrient-rich (N: 2.43%; P: 0.92%; K: 2.09%) vermicompost production. The total phenolic contents declined during the vermicomposting with a lower final content of 21.26 mg/g GAE in 2:3:1 combination of substrates from the initial level (105.56 mg/g GAE). Besides, the concentration of total phenol contents inversely related to the germination index of Brassica juncea (r = -0.761), indicating that the phenolic content could also play an important role in phytotoxicity. Growth and fecundity of Eudrilus eugeniae in 2:3:1 combination revealed the acceptability and rapid decomposition of coir pith substrate into vermifertilizer. | Jayakumar, Mani; Emana, Abdi Nemera; Subbaiya, Ramasamy; Ponraj, Mohanadoss; Kumar, Krishna Kumar Ashok; Muthusamy, Govarthanan; Kim, Woong; Karmegam, Natchimuthu | Haramaya Univ, Dept Chem Engn, Haramaya Inst Technol, Haramaya, Dire Dawa, Ethiopia; Copperbelt Univ, Sch Math & Nat Sci, Dept Biol Sci, Jambo Dr,POB 21692, Riverside, Kitwe, Zambia; Vets Inst Sci Technol & Adv Studies, Sch Life Sci, Dept Biotechnol, Chennai 600117, Tamil Nadu, India; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Govt Arts Coll Autonomous, Dept Bot, Salem 636007, Tamil Nadu, India | Govarthanan, Muthusamy/C-1491-2014; Subbaiya, R/AAR-2948-2021; Kumar, Ashok/AAA-4798-2022; Mani, Jayakumar/AAU-8345-2021; Muthusamy, Govarthanan/C-1491-2014; Ponraj, Mohanadoss/E-9098-2013; Karmegam, Natchimuthu/J-4745-2019; Natchimuthu, Karmegam/J-4745-2019; Emana, Abdi Nemera/HTS-6675-2023 | 57196512530; 57209100730; 55263515700; 55336609200; 57184060400; 54881927600; 55581636400; 6506043230 | elshine@knu.ac.kr;kanishkarmegam@gmail.com; | CHEMOSPHERE | CHEMOSPHERE | 0045-6535 | 1879-1298 | 291 | SCIE | ENVIRONMENTAL SCIENCES | 2022 | 8.8 | 10.7 | 2.11 | 2025-06-25 | 23 | 29 | Coir pith; Eudrilus eugeniae; Green manures; Precomposting; Vermicomposting | INDUSTRY SLUDGE; COCONUT HUSK; PHOSPHORUS; NITROGEN; MATURITY; PAPER | Coir pith; Eudrilus eugeniae; Green manures; Precomposting; Vermicomposting | Animals; Cattle; Female; Lignin; Manure; Oligochaeta; Soil; Fertilizers; Manures; Organic carbon; Plants (botany); Substrates; calcium; cellulase; lignin; organic matter; oxidoreductase; phenol; phosphorus; potassium; urease; coir; Brassica juncea; C:N ratio; Coir pith; Eudrilus eugeniae; Gliricidia sepium; Green manures; Precomposting; Total phenolic content; Vermi-composting; Vermicomposts; composting; concentration (composition); detoxification; dicotyledon; enzyme; enzyme activity; phenolic compound; Article; Brassica juncea; carbon nitrogen ratio; detoxification; Eisenia fetida; Eudrilus; eudrilus eugeniae; fertility; germination; gliricidia sepium; legume; nonhuman; physical chemistry; phytotoxicity; Pleurotus; Sesbania; vermicompost; animal; bovine; female; manure; Oligochaeta; soil; Detoxification | English | 2022 | 2022-03 | 10.1016/j.chemosphere.2021.132675 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Review | Efficiency of microbial fuel cells in the treatment and energy recovery from food wastes: Trends and applications-A review | The rising global population and their food habits result in food wastage and cause an obstacle in its treatment and disposal. Due to the rapid shift in the lifestyle of the human population and urbanization, almost one-third of the food produced is wasted from various sectors like domestic sources, agricultural sectors, and industrial sectors. These food resources squandered are rich in organic biomolecules which can cause complications upon direct disposal in the environment. Conventional disposal methods like composting, landfills and incineration demand high costs besides causing severe environmental and health issues. To overcome these demerits of the conventional methods and to avoid the loss of rich organic food resources, there is an immediate need for a sustainable and eco-friendly solution for the valorization of the food wastes. Microbial fuel cells (MFCs) are gaining attention, due to their ideal approach in the production of electricity and parallel treatment of organic food wastes. The MFCs are significant as an innovative approach using microorganisms and oxidizing the organic food wastes into bio-electricity. In this review, the recent advancements and practices of the MFCs in the field of food waste treatment and management along with electricity production are discussed. The major outcome of this work highlights the setting up of MFC for the treatment of higher volumes of food waste residues and enhancing the bioelectricity production in an optimal condition. For further improvements in the food waste treatments using MFCs, greater understanding and more research needs are to be focused on the commercialization, different operational modes, operational types, and low-cost fabrication coupled with careful examination of scale-up factors. | Kumar, Shanmugam Dilip; Yasasve, Madhavan; Karthigadevi, Guruviah; Aashabharathi, Manimaran; Subbaiya, Ramasamy; Karmegam, Natchimuthu; Govarthanan, Muthusamy | Sri Venkateswara Coll Engn Pennalur Village, Dept Biotechnol, Chennai Bangaluru High Rd, Sriperumbudur 602117, Tamil Nadu, India; Sree Sastha Inst Engn & Technol, Dept Biotechnol, Chennai 600123, Tamil Nadu, India; Copperbelt Univ, Dept Biol Sci, Sch Math & Nat Sci, Jambo Dr, Kitwe 21692, Zambia; Govt Arts Coll Autonomous, Dept Bot, Salem 636007, Tamil Nadu, India; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea | ; Govarthanan, Muthusamy/C-1491-2014; Madhavan, Yasasve/IZD-7011-2023; Subbaiya, R/AAR-2948-2021; Muthusamy, Govarthanan/C-1491-2014; Natchimuthu, Karmegam/J-4745-2019; Karmegam, Natchimuthu/J-4745-2019 | 57751231700; 57209414195; 57192255829; 57280559300; 55263515700; 6506043230; 54881927600 | kanishkarmegam@gmail.com;gova.muthu@gmail.com; | CHEMOSPHERE | CHEMOSPHERE | 0045-6535 | 1879-1298 | 287 | SCIE | ENVIRONMENTAL SCIENCES | 2022 | 8.8 | 10.7 | 4 | 2025-06-25 | 46 | 55 | Agricultural residues; Composting; Food waste treatment; Microbial fuel cells; Organic biomolecules | MUNICIPAL SOLID-WASTE; GREENHOUSE-GAS EMISSIONS; ELECTRICITY-GENERATION; BIOELECTRICITY PRODUCTION; PERFORMANCE EVALUATION; ANAEROBIC-DIGESTION; WATER TREATMENT; TO-ENERGY; MANAGEMENT; ENHANCEMENT | Agricultural residues; Composting; Food waste treatment; Microbial fuel cells; Organic biomolecules | Bioelectric Energy Sources; Electricity; Electrodes; Food; Humans; Incineration; Refuse Disposal; Agricultural wastes; Agriculture; Biomolecules; Biopolymers; Costs; Electrophysiology; Waste incineration; Waste treatment; Cell-be; Cell/B.E; Cell/BE; Energy recovery; Food resources; Food waste; Food waste treatment; Global population; Organic biomolecule; Organics; efficiency measurement; food waste; fuel cell; literature review; microbial activity; trend analysis; waste treatment; article; attention; bioenergy; composting; electricity; energy recovery; food waste; human; incineration; landfill; microbial fuel cell; microorganism; nonhuman; organic food; oxidation; scale up; trend study; valorization; bioenergy; electrode; food; waste disposal; Microbial fuel cells | English | 2022 | 2022-01 | 10.1016/j.chemosphere.2021.132439 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Efficient sonocatalytic degradation of heavy metal and organic pollutants using CuS/MoS2 nanocomposites | Eco-friendly and highly effective catalysts are receiving considerable attention for the removal of heavy-metal ions and organic pollutants. In this study, we developed CuS/MoS2 nanocomposite sonocatalysts to enhance the degradation rate of environmental contaminants by harnessing ultrasonic irradiation. The successful synthesis of nanocomposite sonocatalysts was confirmed by X-ray diffraction (XRD) analysis, and energy-dispersive X-ray spectroscopy. The incorporation of CuS into MoS2 resulted in a flower-like structure with an increased surface area. Importantly, the sonocatalytic efficiency was enhanced by increasing CuS concentration in the nanocomposites, achieving maximum removal efficiencies of 99% and 88.52% for rhodamine B (RhB) and Cr (VI), respectively. In addition, they showed excellent stability and recyclability over five consecutive cycles, without noticeable changes in the nanocomposite structure. Reactive oxygen species (ROS) used for the degradation were identified using ROS scavengers. We believe that this strategy of exploiting nanocomposite sonocatalysts has a great potential in the field of environmental catalysis. | Dharman, Ranjith Kumar; Shejale, Kiran P.; Kim, Sung Yeol | Kyungpook Natl Engn, Sch Mech Engn, Daegu, South Korea; Kyungpook Natl Univ, Sch Convergence, Dept Hydrogen & Renewable Energy, Daegu 702701, South Korea; Yeungnam Univ, Sch Chem Engn, Gyongsan 38541, South Korea | Kim, Sung Yeol/D-1412-2013; Shejale, Kiran/G-3183-2019; kim, sung/D-1412-2013 | 57287207100; 57063450100; 19337822900 | sykim.knu@gmail.com; | CHEMOSPHERE | CHEMOSPHERE | 0045-6535 | 1879-1298 | 305 | SCIE | ENVIRONMENTAL SCIENCES | 2022 | 8.8 | 10.7 | 2.18 | 2025-06-25 | 26 | 30 | MoS 2; CuS; Sonocatalytic degradation; Cr(VI); RhB | NANOROD ARRAYS; PERFORMANCE; REMOVAL; CR(VI) | Cr(VI); CuS; MoS<sub>2</sub>; RhB; Sonocatalytic degradation | Catalysis; Copper; Environmental Pollutants; Molybdenum; Nanocomposites; Reactive Oxygen Species; Chromium compounds; Copper compounds; Degradation; Energy dispersive spectroscopy; Heavy metals; Layered semiconductors; Metal ions; Nanocomposites; Organic pollutants; Rhodium compounds; X ray diffraction analysis; chromium; copper sulfide nanoparticle; heavy metal; molybdenum; nanocomposite; reactive oxygen metabolite; rhodamine B; copper; cupric sulfide; molybdenum; Cr(VI); Degradation rate; Eco-friendly; Environmental contaminant; Metalorganics; Reactive oxygen species; Removal of heavy metal ions; Rhodamine-B; Sonocatalytic degradation; ]+ catalyst; heavy metal; nanocomposite; pollutant; reactive oxygen species; X-ray diffraction; adsorption; Article; catalysis; chemical bond; chemical composition; chemical structure; concentration (parameter); degradation; desorption; energy dispersive X ray spectroscopy; field emission; heavy metal removal; physical chemistry; pollutant; pore size distribution; surface area; synthesis; ultrasound; X ray diffraction; catalysis; chemistry; Molybdenum compounds | English | 2022 | 2022-10 | 10.1016/j.chemosphere.2022.135415 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Electrocatalytic oxidation of antidiabetic drug metformin adsorbed on intercalated MXene | Two-dimensional (2D) Ti3C2Tx transition metal carbide (MXene) nanosheets intercalated with sodium ions (SI-Ti3C2Tx MXene) were used in the adsorption and electrochemical regeneration process for removal of the antidiabetic drug metformin (MF) as a model emerging pollutant. After MF adsorption, SI-Ti3C2Tx MXene oxidized the MF on its surface through its electrocatalytic activity at very low current density and cell potential. For complete oxidation the optimum parameters were 0.525 C g- 1, 0.005 mA cm-2, and pH 6 in absence of NaCl or 26.25 C g- 1 and 0.5 mA cm-2 in the presence of 2.5 w/v% NaCl. The overall regeneration of SI-Ti3C2Tx is governed by a combined mechanism, i.e., desorption followed by degradation. The degradation mechanism, such as direct electron transfer or indirect oxidation, depends on the applied operating conditions. Thus, the inves-tigation suggests that these 2D sheets are good nanoadsorbents as well as good electrocatalysts and proves their usefulness in practical water-treatment applications. | Ghani, Ahsan Abdul; Maile, Nagesh; Tahir, Khurram; Kim, Bolam; Lim, Youngsu; Jang, Jiseon; Lee, Dae Sung | Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak ro, Daegu 41566, South Korea; Univ Karachi, Dept Chem Engn, Main Univ Rd, Karachi 75270, Sindh, Pakistan; Korea Radioact Waste Agcy, R&D Inst Radioact Wastes, 174 Gajeong ro, Daejeon 34129, South Korea | Maile, Nagesh/AFD-8838-2022; Tahir, Khurram/KFS-5321-2024 | 57218294089; 57193804539; 57207114377; 57208922438; 57207112603; 56611137400; 55568524907 | jsjang@korad.or.kr;daesung@knu.ac.kr; | CHEMOSPHERE | CHEMOSPHERE | 0045-6535 | 1879-1298 | 307 | SCIE | ENVIRONMENTAL SCIENCES | 2022 | 8.8 | 10.7 | 0.8 | 2025-06-25 | 10 | 11 | MXene; Metformin; Electrocatalyst; Adsorption; Electrochemical regeneration | WASTE-WATER TREATMENT; ELECTROCHEMICAL REGENERATION; TITANIUM CARBIDE; ANODIC-OXIDATION; TI3C2TX MXENE; REMOVAL; CARBON; ADSORPTION; PERFORMANCE; POLLUTANTS | Adsorption; Electrocatalyst; Electrochemical regeneration; Metformin; MXene | Environmental Pollutants; Hypoglycemic Agents; Metformin; Sodium; Sodium Chloride; Titanium; Water; Adsorption; Carbides; Degradation; Electrocatalysis; Metal ions; Oxidation; Silicon; Sodium chloride; Transition metals; Water treatment; adsorbent; metformin; nanosheet; sodium chloride; sodium ion; titanium carbide; antidiabetic agent; sodium; titanium; water; Antidiabetic drug; Electro-catalytic oxidation; Electrochemical regeneration; Emerging pollutants; Metformins; Mxene; Regeneration process; Sodium ions; Transition metals carbides; Two-dimensional; adsorption; drug; electrochemical method; pollutant; adsorption kinetics; Article; catalysis; cell membrane potential; chemical binding; chemisorption; current density; degradation; desorption; electrochemistry; electron transport; energy dispersive X ray spectroscopy; field emission scanning electron microscopy; Fourier transform infrared spectroscopy; intercalation complex; isotherm; molecular size; oxidation; pH; physisorption; static electricity; synthesis; water pollutant; water treatment; X ray diffraction; X ray photoemission spectroscopy; pollutant; Electrocatalysts | English | 2022 | 2022-11 | 10.1016/j.chemosphere.2022.135767 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | Enhanced photocatalytic degradation of bisphenol A by magnetically separable bismuth oxyiodide magnetite nanocomposites under solar light irradiation | Bismuth oxyiodide/magnetite (BiOI/Fe3O4) nanocomposites were synthesized by a hydrothermal reaction. The synthesized BiOI/Fe3O4 was used to remove bisphenol A (BPA) from an aqueous solution under simulated solar light. The molar ratio of Bi to Fe in BiOI/Fe3O4 significantly affected BPA degradation, with the optimal BiOI/Fe3O4 (2:1) ratio in the composites. Optimum operating conditions such as a catalyst dosage of 1.0 g/L, an initial BPA concentration of 10 mg/L, and pH 7 gave a complete degradation of completely removed BPA within 30 min. The primary reactive oxygen species were verified as superoxide radicals and holes in oxidative species experiments. The magnetic BiOI/Fe3O4 could be easily collected from an aqueous solution by an external magnet, and its reusability was successfully demonstrated through recycling experiments. Furthermore, the derivatives in BiOI/Fe3O4 photocatalytic reactions were investigated, and a possible BPA degradation pathway was proposed. These results show that BiOI/Fe3O4 nanocomposites have great potential for BPA removal from water and wastewater treatment systems. | Kim, Bolam; Jang, Jiseon; Lee, Dae Sung | Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Korea Radioact Waste Agcy, R&D Inst Radioact Wastes, 174 Gajeong Ro, Daejeon 34129, South Korea | 57208922438; 56611137400; 55568524907 | jsjang@korad.or.kr;daesung@knu.ac.kr; | CHEMOSPHERE | CHEMOSPHERE | 0045-6535 | 1879-1298 | 289 | SCIE | ENVIRONMENTAL SCIENCES | 2022 | 8.8 | 10.7 | 0.87 | 2025-06-25 | 11 | 12 | Bismuth oxyiodide; Photocatalysis; Solar light; Magnetic separation; Reuability; Bisphenol A | VISIBLE-LIGHT; EFFICIENT PHOTOCATALYST; COMPOSITE; PHOTODEGRADATION; PERFORMANCE; ADSORPTION; REMOVAL; WATER; BPA; CAPACITY | Bismuth oxyiodide; Bisphenol A; Magnetic separation; Photocatalysis; Reuability; Solar light | Benzhydryl Compounds; Bismuth; Catalysis; Ferrosoferric Oxide; Light; Nanocomposites; Phenols; Bismuth compounds; Degradation; Magnetic separation; Molar ratio; Nanocomposites; Phenols; Photocatalytic activity; Reusability; Wastewater treatment; 4,4' isopropylidenediphenol; bismuth iodide oxide; iron; magnetite; nanocomposite; reactive oxygen metabolite; superoxide; 4,4' isopropylidenediphenol; benzhydryl derivative; bismuth; magnetite; phenol derivative; Bismuth oxyiodide; Bisphenol A; Bisphenols-A; Hydrothermal reaction; Magnetically separable; Photocatalytic degradation; Reuability; Solar light; Solar light irradiation; Synthesised; aqueous solution; bismuth; catalyst; degradation; irradiation; magnetite; nanocomposite; aqueous solution; Article; catalyst; controlled study; dehydration; irradiation; magnetic separation; oxidation; photocatalysis; recycling; simulation; waste water management; catalysis; light; Magnetite | English | 2022 | 2022-02 | 10.1016/j.chemosphere.2021.133040 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Extraction, identification, and environmental risk assessment of microplastics in commercial toothpaste | Microplastics in personal care and food products are given much importance globally due to the adverse impact of microplastics on living beings. In the present study, microplastics from ten different commercially sold toothpaste in India were extracted by vacuum filtration and characterized with microscopic and Fourier transform infrared spectroscopic analyses. Results revealed that colorless fragments and fibers were the micro particle types of common occurrence which ranged from 0.2 to 0.9% weight in the toothpaste with an abundance range of 32.7-83.2%. Fifty percent of the toothpaste samples showed more than 50% microplastic particle abundance indicating that the microplastic plastic particles were added by the manufacturers. The minimum size of microplastics recorded in the present study was 3.5 mu m with a maximum size exceeding 400 mu m. The maximum number of microplastics in the toothpaste was 167, 508 and 193 respectively, distributed in the size range of 400 mu m. The present study recorded four major polymer types, viz., cellophane, polypropylene, polyvinyl chloride, and polyamide in the toothpaste samples. Surprisingly, polyethylene-a common polymer reported in toothpaste was not traced in the present samples. Regarding the Indian context, the current study is a new addition to the knowledge of the occurrence of microplastics in toothpaste. The average annual addition of microplastics into the environment through toothpaste was calculated as 1.4 billion g/year for India, posing a significant threat to the environment. | Madhumitha, Chidhambaram T.; Karmegam, Natchimuthu; Biruntha, Muniyandi; Arun, Alagarsamy; Al Kheraif, Abdulaziz A.; Kim, Woong; Kumar, Ponnuchamy | Alagappa Univ, Dept Anim Hlth & Management, Toxicogen & Syst Toxicol Lab, Karaikkudi 630003, Tamil Nadu, India; Govt Arts Coll Autonomous, Dept Bot, Salem 636007, Tamil Nadu, India; Alagappa Univ, Dept Anim Hlth & Management, Vermitechnol Lab, Karaikkudi 630003, Tamil Nadu, India; Alagappa Univ, Dept Microbiol, Karaikkudi 630003, Tamil Nadu, India; King Saud Univ, Coll Appl Med Sci, Dent Hlth Dept, POB 10219, Riyadh 11433, Saudi Arabia; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea | Muniyandi, BIRUNTHA/G-2438-2019; Arun, A./F-8986-2019; Natchimuthu, Karmegam/J-4745-2019; Ponnuchamy, Kumar/D-3470-2013; Arun, Alagarsamy/F-8986-2019; , BIRUNTHA/G-2438-2019; Karmegam, Natchimuthu/J-4745-2019 | 57460117800; 6506043230; 57203752025; 57078221100; 6505582899; 55581636400; 55173720800 | elshine@knu.ac.kr;kumarp@alagappauniversity.ac.in; | CHEMOSPHERE | CHEMOSPHERE | 0045-6535 | 1879-1298 | 296 | SCIE | ENVIRONMENTAL SCIENCES | 2022 | 8.8 | 10.7 | 3.71 | 2025-06-25 | 46 | 53 | Microplastics; Toothpaste; Polyethylene; Cellophane; Risk assessment | PERSONAL CARE; ESTIMATED EMISSIONS; COSMETIC PRODUCTS; MICROBEADS; MARINE; FATE; SEA | Cellophane; Microplastics; Polyethylene; Risk assessment; Toothpaste | Environmental Monitoring; Microplastics; Plastics; Polymers; Risk Assessment; Toothpastes; Water Pollutants, Chemical; Cellophane; Cellulose; Chlorine compounds; Food products; Particle size analysis; Polyethylenes; Polypropylenes; Polyvinyl chlorides; Spectroscopic analysis; cellophane; microplastic; polyamide; polyethylene terephthalate; polymer; polypropylene; polyvinylchloride; toothpaste; plastic; toothpaste; Environmental risk assessment; Fourier transform infrared; Infrared spectroscopic analysis; Micro particles; Microplastic particles; Microplastics; Personal care; Risks assessments; Toothpaste; Vacuum filtration; environmental risk; plastic; polymer; risk assessment; Article; attenuated total reflectance Fourier transform infrared spectroscopy; DNA extraction; environmental risk; extraction; filtration; fluorescence microscopy; Fourier transform; infrared radiation; infrared spectroscopy; mass fragmentography; microbial diversity; oxidative stress; particle size; pH; phylogeny; risk assessment; scanning electron microscopy; vacuum; X ray diffraction; chemistry; environmental monitoring; risk assessment; water pollutant; Risk assessment | English | 2022 | 2022-06 | 10.1016/j.chemosphere.2022.133976 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Fe(III)-doped activated biochar sorbents trigger mitochondrial dysfunction with oxidative stress on Daphnia magna | This study investigates the ecotoxicological effects of the synthesized Fe(III)-doped activated biochar (FeAB) sorbents using Daphnia magna and elucidates the underline mechanism of potential oxidative stress that may be induced by the sorbent. The EC50 value was determined to be 68.8 mg L-1. The superoxide dismutase (SOD) activity of D. magna was generally inhibited and the glutathione (GSH) level was significantly reduced even at the lowest FeAB concentration used (i.e., 0.12 mg L-1). This means that the antioxidant system of D. magna can be significantly inhibited by exposure to even a small amount of FeAB. While the higher reactive oxygen species (ROS)/reactive nitrogen species (RNS) levels in the exposed samples than the control at low FeAB concentrations (i.e., <15.63 mg L-1) suggest the failure of the anti-oxidation mechanism of SOD and GSH, the lower average levels of ROS/RNS in the exposed samples than the control at relatively high concentrations (i.e., 31.25-1000 mg L-1) can be explained by the reduced ROS/RNS production due to cell damage. Furthermore, the mitochondrial complex III activities were significantly inhibited in a FeAB concentration-dependent manner. Overall, the FeAB sorbent down-regulates the antioxidant mechanism, and this, together with the inefficient mitochondria, increases the ROS generation, leading to mitochondrial dysfunction again. The potential oxidative stress of FeAB on D. manga observed in this study suggests that the environmental application of FeAB needs to adopt a method that can minimize the direct contact between FeAB and organisms. | Lee, Songhee; Lee, Sungjong; Jho, Eun Hea; Shin, Sooim; Park, Chang Min | Chonnam Natl Univ, Interdisciplinary Program Bioenergy & Biomat, Grad Sch, 77 Yongbong Ro, Gwangju 61186, South Korea; Hankuk Univ Foreign Studies, Dept Environm Sci, 81 Oedae Ro, Yongin 17035, Gyeonggi Do, South Korea; Chonnam Natl Univ, Dept Agr & Biol Chem, 77 Yongbong Ro, Gwangju 61186, South Korea; Chonnam Natl Univ, Coll Engn, Dept Biotechnol & Bioengn, 77 Yongbong Ro, Gwangju 61186, South Korea; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea | Jho, Eun Hea/ADK-1851-2022; Park, Chang Min/CAA-8506-2022; Jho, Eun Hea/D-3024-2011 | 57252580400; 57195595806; 35082050000; 26435504000; 57209588953 | ejho001@jnu.ac.kr;sooim.shin@jnu.ac.kr; | CHEMOSPHERE | CHEMOSPHERE | 0045-6535 | 1879-1298 | 288 | SCIE | ENVIRONMENTAL SCIENCES | 2022 | 8.8 | 10.7 | 0.36 | 2025-06-25 | 5 | 5 | Daphnia magna; Toxicity; Oxidative stress; Mitochondrial dysfunction; Antioxidant defense | MAGNETITE NANOPARTICLES; COMPLEX-III; ADSORPTION; TOXICITY; MECHANISMS; CADMIUM | Antioxidant defense; Daphnia magna; Mitochondrial dysfunction; Oxidative stress; Toxicity | Animals; Charcoal; Daphnia; Ferric Compounds; Mitochondria; Oxidative Stress; Water Pollutants, Chemical; Ablation; Antioxidants; Enzymes; Iron compounds; Mitochondria; charcoal; glutathione; iron; reactive oxygen metabolite; superoxide dismutase; ubiquinol cytochrome c reductase; biochar; charcoal; ferric ion; Antioxidant defence; Biochar; Daphnia magna; Ecotoxicological effects; Gluthathione; Mitochondrial dysfunction; Reactive nitrogen species; Reactive oxygen species; Superoxide dismutase activities; Synthesised; concentration (composition); crustacean; hypertrophic environment; iron; oxidative stress; reactive oxygen species; Article; carbonization; comparative study; controlled study; Daphnia magna; disorders of mitochondrial functions; EC50; ecotoxicity; nonhuman; oxidation reduction reaction; oxidative stress; scanning electron microscopy; solid phase extraction; surface area; surface property; survival rate; toxicity testing; animal; Daphnia; mitochondrion; oxidative stress; toxicity; water pollutant; Oxidative stress | English | 2022 | 2022-02 | 10.1016/j.chemosphere.2021.132608 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Functionalized metal-organic framework-derived carbon: Effective adsorbent to eliminate methylene blue, a small cationic dye from water | Elimination of organic dyes from wastewater is very important for our safe environment and sound health. In this work, adsorptive removal of cationic dyes, especially small ones, was investigated with carbonaceous materials to develop a competitive adsorption technology. To improve the performance of metal-organic framework (MOF)-derived carbons (MDCs) in dye adsorption, an MDC, derived from a MOF (MAF-6), was oxidatively functionalized with ammonium persulfate solutions (APSs). Although the porosity of pristine MDC decreased with functionalization via oxidation, functionalized MDCs (FMDCs), especially FMDC(1.0) that was obtained via treating MDC with APS (1.0 M), showed remarkable performances in the adsorption of small cationic dyes like methylene blue (MB) and azure B. For example, FMDC(1.0) had the maximum adsorption capacity (Q(o)) of 625.0 mg/g (for MB) which is larger than any reported value with carbonaceous materials. Moreover, the obtained Q(o) was around 4 and 2 times that of activated carbon with Q(o) of 160 mg/g and MDC with Q(o) of 298 mg/g, respectively. On the contrary, oxidative treatment of MDC was negative in adsorption of an anionic dye such as methyl orange. Moreover, the functionalized MDC was not very effective in the adsorption of cationic dyes with large sizes (like brilliant green, crystal violet, Janus green B, and rhodamine B) because of the limited pore size of the studied adsorbent FMDC(1.0). The remarkable adsorption of MB over FMDC(1.0) could be explained by electrostatic and pi-pi interactions. Finally, the facile recyclability of the FMDC(1.0) in MB adsorption was confirmed via successive adsorptions, FT-IR, and nitrogen adsorption; therefore, FMDC(1.0) can be suggested as a potential adsorbent to remove cationic dyes, especially with small molecular sizes. | Hossain, Md.

| ○ | ○ | Article | Highly efficient degradation of phenolic compounds by Fe(II)-activated dual oxidant (persulfate/calcium peroxide) system | This study demonstrates the feasibility, reaction mechanisms, and potential of practical applications of a dual oxidant (DuOx) system comprising calcium peroxide (CP) and persulfate (PS) catalyzed using Fe(II) [PS/CP/Fe (II)]. The DuOx system was superior in phenol degradation to single oxidant systems, i.e., PS/Fe(II) or CP/Fe(II), with 95.5% phenol removal under an optimum condition of a phenol/PS/CP/Fe(II) molar ratio of 1/1/5/6 ([Phenol]0=0.5 mM). Based on scavenger studies and electron spin resonance (ESR) spectroscopy, the phenol removal in the DuOx system was barrierless, with negative activation energy assisted by robust reactive species. The phenol degradation results in the presence of methanol, t-butanol, L-histidine, and NaN3. The ESR spectroscopy indicates that phenol degradation is attributed dominantly to O-1(2) generated by recombining O-2(center dot-) and radicals, such as hydroxyl (HO center dot) and sulfate (SO4 center dot-). The performance of the DuOx system was highly efficient in pH 3-11, up to 10 mM Cl-, SO42-, or NO3-, and up to 50 mg/L humic acids but was strongly suppressed by more than 10 mM HCO3- and H2PO4- . In addition, the DuOx system was efficient in phenol removal in natural groundwater as well as removing and mineralizing other phenolic compounds (PCs) such as bisphenol A, chlorophenol, dichlorophenol, trichlorophenol, and nitrophenol. These results provide insights into the reactions induced by the DuOx system and confirm its applicability of in situ chemical oxidation in refractory organic pollutants. | Al Masud, Md Abdullah; Kim, Do Gun; Shin, Won Sik | Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea; Sunchon Natl Univ, Dept Environm Engn, Sunchon 57922, Jeollanam Do, South Korea | Masud, Md Abdullah Al/JEF-1055-2023 | 57542255300; 36623899900; 23019870800 | dgkim@scnu.ac.kr;wshin@knu.ac.kr; | CHEMOSPHERE | CHEMOSPHERE | 0045-6535 | 1879-1298 | 299 | SCIE | ENVIRONMENTAL SCIENCES | 2022 | 8.8 | 10.7 | 2.47 | 2025-06-25 | 34 | 34 | Calcium peroxide; Dual oxidant; Natural groundwater; Persulfate; Radical | HYDROGEN-PEROXIDE; POLYCHLORINATED-BIPHENYLS; OXIDATION PROCESSES; HYDROXYL RADICALS; SODIUM PERSULFATE; AQUEOUS-SOLUTION; NITRIC-OXIDE; BISPHENOL-A; SULFATE; IONS | Calcium peroxide; Dual oxidant; Natural groundwater; Persulfate; Radical | Ferrous Compounds; Oxidants; Oxidation-Reduction; Peroxides; Phenol; Phenols; Sulfates; Water Pollutants, Chemical; Activation energy; Amino acids; Biodegradation; Calcium compounds; Electron spin resonance spectroscopy; Groundwater; Iron compounds; Magnetic moments; Molar ratio; Organic pollutants; Oxidation; Peroxides; Phenols; Sulfur compounds; 4,4' isopropylidenediphenol; butanol; calcium; chlorophenol; ferrous ion; histidine; humic acid; hydroxyl group; methanol; nitrophenol; peroxide; sodium azide; sulfate; calcium peroxide; ferrous ion; oxidizing agent; peroxide; phenol; phenol derivative; Calcium peroxides; Dual oxidant; Natural groundwater; Persulphate; Phenol degradation; Phenolic compounds; Phenols removal; Radical; Reaction mechanism; Reaction potential; feasibility study; groundwater; methanol; mineralization; organic pollutant; phenolic compound; radical; Article; catalysis; degradation; electron spin resonance; feasibility study; nonhuman; oxidation; pH; pollutant; reaction analysis; waste component removal; chemistry; oxidation reduction reaction; water pollutant; Oxidants | English | 2022 | 2022-07 | 10.1016/j.chemosphere.2022.134392 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Human interaction recognition framework based on interacting body part attention | Human activity recognition in videos has been widely studied and has recently gained significant ad -vances with deep learning approaches; however, it remains a challenging task. In this paper, we propose a novel framework that simultaneously considers both implicit and explicit representations of human in-teractions by fusing information of local image where the interaction actively occurred, primitive motion with the posture of individual subject's body parts, and the co-occurrence of overall appearance change. Human interactions change, depending on how the body parts of each human interact with the other. The proposed method captures the subtle difference between different interactions using interacting body part attention. Semantically important body parts that interact with other objects are given more weight during feature representation. The combined feature of interacting body part attention-based individ-ual representation and the co-occurrence descriptor of the full-body appearance change is fed into long short-term memory to model the temporal dynamics over time in a single framework. The experimen-tal results on five widely used public datasets demonstrate the effectiveness of the proposed method to recognize human interactions from videos. (c) 2022 Elsevier Ltd.
