| 1 | Algal toxicity induced by effluents from textiledyeing wastewater treatment plants显示文摘This research aimed to evaluate the alga Scenedesmus obliquus toxicity induced by textiledyeing effluents(TDE).The toxicity indicator of TDE in alga at the physiological(algal growyth),biochemical(chlorophyll-a(Chl-a)synthesis and superoxide dismutase(SOD)activity)and structural(cell membrane integrity)level were investigated.Then we further study the relationship among toxicity indicators at physiological and biochemical level,and supplemented by research on algal biomacromolecules.According to the analysis of various endpoints of the alga,the general sensitivity sequence of toxicity endpoints of Scenedesmus obliquus was:SOD activity>Chl-a synthesis>algal growth.The stimulation rate of SOD activity increased from day 3(57.25%~83.02%)to day 6(57.25%~103.81%),and then decreased on day 15(-4.23%^-32.96%),which indicated that the antioxidant balance system of the algal cells was destroyed.The rate of Chl-a synthesis inhibition increased gradually,reaching19.70%~79.39%on day 15,while the rate of growth inhibition increased from day 3(-12.90%~10.16%)to day 15(-21.27%~72.46%).Moreover,the algal growth inhibition rate was positively correlated with the inhibition rate of SOD activity or Chl-a synthesis,with the correlation coefficients were 0.6713 and 0.5217,respectively.Algal cells would be stimulating to produce excessive reactive oxygen species,which would cause peroxidation in the cells,thereby destroying chloroplasts,inhibiting chlorophyll synthesis and reducing photosynthesis.With increasing exposure time,irreversible damage to algae can lead to death.This study is expected to enhance our understanding of the ecological risks through algal tests caused by TDE. | Hualing Cai Jieying Liang Xun-an Ning Xiaojun Lai Yang Li | 2020 | Journal of Environmental Sciences2020，32，5： | 6 |
| 2 | Advancement and new perspectives of using formulated reactive amine blends for post-combustion carbon dioxide (CO_(2)) capture technologies显示文摘Chemical absorption using amine-based solvents have proven to be the most studied,as well as the most reliable and efficient technology for capturing carbon dioxide(CO_(2))from exhaust gas streams and synthesis gas in all combustion and industrial processes.The application of single amine-based solvents especially the very reactive monoethanolamine(MEA)is associated with a parasitic energy demand for solvent regeneration.Since regeneration energy accounts for up to threeequarters of the plant operating cost,efforts in its reduction have prompted the idea of using blended amine solvents.This review paper highlights the success achieved in blending amine solvents and the recent and future technologies aimed at increasing the overall volumetric mass transfer coefficient,absorption rate,cyclic capacity and greatly minimizing both degradation and the energy for solvent regeneration.The importance of amine biodegradability(BOD)and low ecotoxicity as well as low amine volatility is also highlighted.Costs and energy penalty indices that influences the capital and operating costs of CO_(2) capture process was also highlighted.A new experimental method for simultaneously estimating amine cost,degradation rate,regeneration energy and reclaiming energy is also proposed in this review paper. | Chikezie Nwaoha Teeradet Supap Raphael Idem Chintana Saiwan Paitoon Tontiwachwuthikul Mohammed JAL-Marri Abdelbaki Benamor | 2017 | Petroleum2017，3，1： | 4 |
| 3 | Emerging Organic Contaminants in Chinese Surface Water:Identification of Priority Pollutants显示文摘The occurrence and impacts of emerging organic contaminants(EOCs)in the aquatic environment have gained widespread attention over the past two decades.Due to large number of potential contaminants,monitoring campaigns,treatment plants,and proposed regulations should preferentially focus on specific pollutants with the highest potential for ecological and human health effects.In the present study,a multi-criteria screening approach based on hazard and exposure potentials was developed for prioritization of 405 unregulated EOCs already present in Chinese surface water.Hazard potential,exposure potential,and risk quotients for ecological and human health effects were quantitatively analyzed and used to screen contaminants.The hazard potential was defined by contaminant persistence,bioaccumulation,ecotoxicity,and human health effects;similarly,the exposure potential was a function of contaminant concentration and detection frequency.In total,123 compounds passed the preselection process,which involved a priority index equal to the normalized hazard potential multiplied by the normalized exposure potential.Based on the prioritization scheme,11 compounds were identified as top-priority,and 37 chemicals were defined as high-priority.The results obtained by the priority index were compared with four other prioritization schemes based on exposure potential,hazard potential,or risk quotients for ecological effects or human health.The priority index effectively captured and integrated the results from the more simplistic prioritization schemes.Based on identified data gaps,four uncertainty categories were classified to recommend:①regular monitoring,derivation of environmental quality standards,and development of control strategies;②increased monitoring;③fortified hazard assessment;and④increased efforts to collect occurrence and toxicity data.Overall,20 pollutants were recommended as priority EOCs.The prioritized list of contaminants provides the necessary information for authoritative regulations to monitor,control,evaluate,and manage the risks of environmentally-relevant EOCs in Chinese surface water. | Mengmeng Zhong Tielong Wang Wenxing Zhao Jun Huang Bin Wang Lee Blaney Qingwei Bu Gang Yu | 2022 | Engineering2022，8，4： | 3 |
| 4 | Perspectives on ecological risks of microplastics and phthalate acid esters in crop production systems显示文摘Microplastics(MPs)and phthalate acid esters(PAEs)co-occur as emerging contaminants of global importance.Their abundance in soil is of increasing concern as plastic-intensive practices continue.Mulching with plastic films,inclusion in fertilizers,composts,sludge application,and wastewater irrigation are all major and common sources of MPs and PAEs in soil.Here,we review studies on the concentration and effects of MPs and PAEs in soil.While there is limited research on the interactions between MPs and PAEs in agroecosystems,there is evidence to suggest they could mutually affect soil ecology and plant growth.Therefore,we propose new research into 1)establishing an efficient,accurate,and simple method to quantify different types of microplastics in soils and plants;2)exploring the behavior and understanding the mechanisms of co-transfer,transformation,and interactions with soil biota(especially in vegetable production systems);3)assessing the risk and consequences of combined and discreet impacts of MPs and PAEs on plants and soil biota,and 4)preventing or reducing the transfer of MPs and PAEs into-and within-the food chain. | Fang Wang Yu Wang Leilei Xiang Marc Redmile-Gordon Chenggang Gu Xinglun Yang Xin Jiang DamiàBarceló | 2022 | Soil Ecology Letters2022，4，2： | 1 |
| 5 | Palm oil biodiesel:An assessment of PAH emissions,oxidative potential and ecotoxicity of particulate matter显示文摘This work assessed the impact of fuelling an automotive engine with palm biodiesel(pure,and two blends of 10%and 20%with diesel,B100,B10 and B20,respectively)operating under representative urban driving conditions on 17 priority polycyclic aromatic hydrocarbon(PAH)compounds,oxidative potential of ascorbic acid(OP^(AA)),and ecotoxicity through D aphnia pulex mortality test.PM diluted with filtered fresh air(WD)gathered in a minitunel,and particulate matter(PM)collected directly from the exhaust gas stream(W/oD)were used for comparison.Results showed that PM collecting method significantly impact PAH concentration.Although all PAH appeared in both,WD and W/oD,higher concentrations were obtained in the last case.Increasing biodiesel concentration in the fuel blend decreased all PAH compounds,and those with 3 and 5 aromatic rings were the most abundant.Palm biodiesel affected both OP^(AA)and ecotoxicity.While B10 and B20 exhibited the same rate of ascorbic acid(AA)depletion,B100 showed significant faster oxidation rate during the first four minutes and oxidized 10%more AA at the end of the test.B100 and B20 were significantly more ecotoxic than B10.The lethal concentration LC50 for B10 was 6.13 mg/L.It was concluded that palm biodiesel decreased PAH compounds,but increased the oxidative potential and ecotoxicity. | Silvana Arias Francisco Molina John R.Agudelo | 2021 | Journal of Environmental Sciences2021，33，3： | 1 |
| 6 | Evaluation of toxicity profiles of rare earth elements salts(lanthanides)显示文摘The presented study aims to extend the knowledge of toxicological profile of rare earth elements salts(REEs).The basal toxicity test performed comprised assessment of cytotoxicity(3 T3 Balb/c Neutral Red Uptake Test)that allows for calculation of LD50(rats)on the basis of the concentration which leads to a50%reduction in cell growth(IC50).Environmental toxicity was addressed by the Tubifex tubifex(T.t.)express test.The in vitro skin irritation(OECD TG 439)and skin corrosion tests(OECD TG 431)utilizing the 3 D in vitro reconstructed human epidermal model EpiDerm(MatTek IVSL,SK)were used for assessment of skin irritation and corrosion potential hazard of REEs.Mutagenic effects were determined using the bacterial reverse mutation assay(Ames Test)on 5 Salmonella typhimurium strains with and without metabolic activation(OECD TG 471).Endocrine disruption was evaluated by means of a yeastbased assay YES/YAS(Xenometrix,CH).Skin sensitization was assessed using the LuSens assay,based on a genetically modified human keratinocyte cell line(OECD TG 442 D).The tested REEs have no potential of mutagenicity or skin sensitization,exhibit very weak endocrine disruption potential and only exceptional local irritation/corrosion effects for thulium(Ⅲ)chloride anhydrous,but have acute and chronic toxic effects on the aquatic environment. | M.Rucki K.Kejlov A.Vlkov D.Jirova M.Dvorakova L.Svobodova H.Kandarova S.Letasiova H.Kolarova M.Mannerstrom T.Heinonen | 2021 | Journal of Rare Earths2021，39，2： | 1 |
| 7 | Toxic effect of sodium perfluorononyloxy-benzenesulfonate on Pseudomonas stutzeri in aerobic denitrification,cell structure and gene expression显示文摘The toxicities of sodium perfluorononyloxy-benzenesulfonate(OBS)to animals and plants are similar to those of perfluorooctane sulfonate.However,the mechanism of its toxicity to aerobic denitrifying bacteria is still unclear.In the present study,the ecotoxicity of OBS on an aerobic denitrifying strain,Pseudomonas stutzeri,was evaluated.The results showed that a dosage of OBS clearly affected the growth and aerobic denitrification of P.stutzeri.When compared with an unamended control,the degradation efficiency of the total nitrogen decreased by 30.13%during exposure to 200 mg/L of OBS,and the complete degradation time of nitrate-nitrogen was delayed by 4 h.The lactate dehydrogenase and superoxide dismutase produced by the bacteria increased with the concentration of OBS,and reactive oxygen species were also detected by confocal laser scanning microscope imaging.Transmission electron microscope imaging revealed chromosome deformation of the cells and damage to cell content;moreover,outer membrane vesicles were secreted from the bacteria,which was the important detoxification mechanism of P.stutzeri to OBS.Expression of the genes involved in aerobic nitrification and oxidative stress were also changed under OBS stress,which further confirmed the toxicity of OBS to P stutzeri.This study reveals the environmental exposure risk of OBS from the perspective of microorganisms. | Yi Qian Weichuan Qiao Yunhao Zhang | 2021 | Frontiers of Environmental Science & Engineering2021，15，5： | 1 |
| 8 | Plastic occurrence,sources,and impacts in Antarctic environment and biota显示文摘Several studies have documented that plastic pollution is affecting one of the most remote and pristine regions of our planet,Antarctica.Plastics of different size and polymeric composition have been retrieved in Antarctic sea ice,surface waters and sediments,with microplastics(mostly fibers)found both in terrestrial and marine organisms.Such evidence raises concerns about potential detrimental effects on biodiversity and ecosystem functions.The present review aims to report the most up-to-date knowledge on occurrence and distribution of plastic pollution in the Antarctic environment and biota including interaction with microorganisms,potential sources,and its impact on Antarctic biota.Our understanding of plastic pollution in this polar region will help us define the human footprint in Antarctica and predict future ecological risks. | Gabriella Caruso Elisa Bergami Neelu Singh Ilaria Corsi | 2022 | Water Biology and Security2022，1，2： | 1 |
| 9 | The accumulation and toxicity of ZIF-8 nanoparticles in Corbicula fluminea显示文摘Metal-organic frameworks(MOFs)are promising new materials that have been intensively studied and possibly applied to various environmental remediation.However,little is known about the fate and risk of MOFs to living organisms in thewater environment.Here,the toxic effects of ZIF-8 nanoparticles(NPs)on benthic organisms were confirmed by sub-chronic toxicity experiments(7 and 14 days)using Corbicula fluminea as the model organism.With exposure doses ranging from 0 to 50 mg/L,ZIF-8 NPs induced oxidative stress behaviors similar to the hormesis effect in the tissues of C.fluminea.The oxidative stress induced by ZIF-8 NPs and the released Zn^(2+)was the crucial cause of the toxic effects.Besides,we also found that the ZIF-8 NPs and dissolved Zn^(2+)may result in different mechanisms of toxicity and accumulation depending on the dosages.The Zn^(2+)release rate of ZIF-8NPswas high at low dosages,leading to a higher proportion of Zn^(2+)taken up by C.fluminea than the particulate ZIF-8.Conversely,at high dosages,C.fluminea mainly ingested the ZIF-8 NPs and resulted in increased mortality.The results have important implications for understanding the fate and biological effects of ZIF-8 in natural aquatic environments. | Cuilian Yang Jia Wen Zhuangzhuang Xue Xiyan Yin Yangfang Li Li Yuan | 2023 | Journal of Environmental Sciences2023，，5： | 1 |
| 10 | The mechanism of different cyanobacterial responses to glyphosate显示文摘Glyphosate, the most extensively used herbicide globally, has raised ecotoxicological concerns because it can be transported into the aquatic environment and cause adverse effects on the aquatic system. However, the functional mechanism of glyphosate on cyanobacteria are not completely disentangled. In this study, we selected six common cyanobacteria to evaluate glyphosate effects on cyanobacterial growth in monoculture experiment. Results showed that the growth of five tested cyanobacterial species were promoted under different degrees, and only Pseudanabaena was inhibited by glyphosate. In the phylogenetic tree based on gene sequences of 5-enol-pyruvylshikimate-3-phosphate synthase(EPSPS),a target for glyphosate, we found that the position of Pseudanabaena is the closest to plant,which was sensitive to glyphosate, thereby explaining the inhibitory effect of Pseudanabaena following glyphosate exposure. The primary degraded metabolites or analogs did not induce cyanobacterial growth, laterally demonstrating that glyphosate was used as a source of phosphorus to accelerate cyanobacterial growth because phosphorus levels increased in the medium of glyphosate treatment. Overall, this study provides a better understanding of the influence of glyphosate on the composition of aquatic microbiota and explains the mechanism of cyanobacterial response to glyphosate. | Wei Lin Zhenyan Zhang Yiling Chen Qi Zhang Mingjing Ke Tao Lu Haifeng Qian | 2023 | Journal of Environmental Sciences2023，，3： | 0 |

| 12 | In vitro toxicity of particulate matter emissions from residential pellet combustion显示文摘Particulate matter emissions(PM10)from the combustion,in a residential stove,of two com-mercial brands of certified(ENplus A1)pellets,a non-certified brand and laboratory made pellets of acacia were tested for their ability to induce ecotoxic,cytotoxic,and mutagenic re-sponses in unicellular organisms and a human cell line.Ecotoxicity was evaluated through the Vibrio fischeri bioluminescence inhibition assay.Moreover,cytotoxicity was assessed at two time points(24-and 48-hr)through two complementary techniques in order to evaluate the cellular metabolic activity and membrane integrity of human lung epithelial cells A549.The Ames test using two Salmonella typhimurium strains(TA100 and TA98)was employed to assess the mutagenic potential of the polycyclic aromatic hydrocarbon fraction extracted from the PM10 samples.Results obtained with the bioluminescent bacteria indicated that only particles from the combustion of acacia pellets were toxic.All samples induced im-pairment on the A549 cells metabolic activity,while no significant release of lactate dehy-drogenase was recorded.PM10 emissions from acacia pellets were the most cytotoxic,while samples from both certified pellets evoked significant cytotoxicity at lower doses.Cytotox-icity time-dependency was only observed for PM10 from the combustion of acacia pellets and one of the brands of certified pellets.Mutagenic activity was not detected in both S.typhi murium strains.This study emphasises the role of the raw material for pellet manu-facturing on the toxicological profile of PM emissions.Alternative raw materials should be deeply investigated before their use in pelletisation and combustion in residential appli-ances. | Estela D.Vicente Daniela Figueiredo Catia Goncalves Isabel Lopes Helena Oliveira Nora Kovats Teresa Pinheiro Celia A.Alves | 2022 | Journal of Environmental Sciences2022，34，5： | 0 |
| 13 | Copper-uptake mediated by an ecofriendly zwitterionic ionic liquid: A new challenge for a cleaner bioeconomy显示文摘This study aims to investigate the ability of an imidazolium biobased Zwitterionic Ionic Liquids(ZILs)in enhancing the phytoavailability of copper from garden(G)and vineyard(V)soils using the model plant ryegrass.Uncontaminated and artificially contaminated CuSO_(4) soils,unamended and ZIL-amended soil modalities were designed.The copper/ZIL molar ratio(1/4)introduced was rationally established based on molecular modeling and on the maximal copper concentration in artificially contaminated soil.Higher accumulation of copper in the shoots was detected for the uncontaminated and copper contaminated ZIL amended V soils(18.9 and 23.3 mg/kg,respectively)contrary to G soils together with a ZIL concentration of around 3%(W/W)detected by LC-MS analyses.These data evidenced a Cu-accumulation improvement of 38%and 66%compared to non-amended V soils(13.6 and 13.9 mg/kg respectively).ZIL would be mainly present under Cu(II)-ZIL_(4) complexes in the shoots.The impact on the chemical composition of shoot was also studied.The results show that depending on the soils modalitity,the presence of free copper and/or ZIL led to different chemical compositions in lignin and monomeric sugar contents.In the biorefinery context,performances of enzymatic hydrolysis of shoots were also related to the presence of both ZIL and copper under free or complex forms.Ecotoxicity assessment of the vineyard soil samples indicated that the quantity of copper and ZIL remaining in the soils had no significant toxicity.ZIL amendment in a copper-contaminated soil was demonstrated as being a promising way to promote the valorization of phytoremediation plants. | Marie E.Vuillemin Christophe Waterlot Anthony Verdin Sylvain Laclef Christine Cézard David Lesur Catherine Sarazin Dominique Courcot Caroline Hadad Eric Husson Albert Nguyen Van Nhien | 2023 | Journal of Environmental Sciences2023，，8： | 0 |
| 14 | Environmental pollution with psychiatric drugs显示文摘Among all contaminants of emerging interest,drugs are the ones that give rise to the greatest concern.Any of the multiple stages of the drug's life cycle(production,consumption and waste management)is a possible entry point to the different environmental matrices.Psychiatric drugs have received special attention because of two reasons.First,their use is increasing.Second,many of them act on phylogenetically highly conserved neuroendocrine systems,so they have the potential to affect many non-target organisms.Currently,wastewater is considered the most important source of drugs to the environment.Furthermore,the currently available wastewater treatment plants are not specifically prepared to remove drugs,so they reach practically all environmental matrices,even tap water.As drugs are designed to produce pharmacological effects at low concentrations,they are capable of producing ecotoxicological effects on microorganisms,flora and fauna,even on human health.It has also been observed that certain antidepressants and antipsychotics can bioaccumulate along the food chain.Drug pollution is a complicated and diffuse problem characterized by scientific uncertainties,a large number of stakeholders with different values and interests,and enormous complexity.Possible solutions consist on acting at source,using medicines more rationally,eco-prescribing or prescribing greener drugs,designing pharmaceuticals that are more readily biodegraded,educating both health professionals and citizens,and improving coordination and collaboration between environmental and healthcare sciences.Besides,end of pipe measures like improving or developing new purification systems(biological,physical,chemical,combination)that eliminate these residues efficiently and at a sustainable cost should be a priority.Here,we describe and discuss the main aspects of drug pollution,highlighting the specific issues of psychiatric drugs. | Julene Argaluza Saioa Domingo-Echaburu Gorka Orive Juan Medrano Rafael Hernandez Unax Lertxundi | 2021 | World Journal of Psychiatry2021，11，10： | 0 |
