| 1 | Removal of dispersant-stabilized carbon nanotubes by regular coagulants显示文摘Coagulation followed by sedimentation,as a conventional technique in the water treatment plant,can be the first line of defense against exposures of carbon nanotubes(CNTs) to aquatic organisms and human beings,which has been rarely documented.This study investigated the removal of dispersant-stabilized CNT suspensions by poly aluminum chloride(PACl) and KAl(SO 4) 2 ·12H 2 O(alum),with a focus on the effects of dispersant type,coagulant type and dosage.PACl performed better than alum in the removal of tannic acid-,humic acid-,and sodium dodecyl benzenesulfonate-stabilized CNTs,but worse for polyethylene glycol octylphenyl ether(TX100)-stabilized CNTs.Neither coagulant could effectively precipitate cetyltrimethyl ammonium bromide-stabilized CNTs.The removal by PACl first increased up to a plateau and then decreased with the continued increase of coagulant dosage.However,the removal rates leveled off but did not decrease after achieving their highest level with the continued addition of alum.The coagulation and flocculation of the CNT suspensions by PACl could be regulated mainly by the mechanism of adsorption charge neutralization,whereas the coagulation by alum mainly involved electrical double-layer compression. | Ni Liu Changli Liu Jing Zhang Daohui Lin | 2012 | Journal of Environmental Sciences2012，24，8： | 6 |
| 2 | Sonication-assisted dispersion of carbon nanotubes in aqueous solutions of the anionic surfactant SDBS:The role of sonication energy显示文摘Sonication is a powerful technique to promote the dispersion of carbon nanotubes(CNTs) and enhance their solubility;this is necessary for CNT applications,especially in the biochemical and biomedical fields.In this study,batch experiments were conducted to evaluate the role of sonication energy on the dispersion of CNTs in the presence of a widely used anionic surfactant,sodium dodecylbenzene sulfonate(SDBS).It was observed that the concentration of dispersed CNTs in the SDBS solution depended on the sonication energy,but not the sonication time or output power of the sonicator alone.The amount of dispersed CNTs was positively correlated with the concentrations of SDBS and CNTs,and the length of the CNTs.The promotion of oxygen-containing functional groups on the dispersed CNTs was observed at relatively low sonication energies.The optimal energy,i.e.the minimum energy supplied by sonication to achieve a saturated suspension of dispersed CNTs in the SDBS solution,was CNT diameter-dependent,because of the larger vdW forces between tubes of smaller diameter.An exponential decay curve was constructed for the optimal energy values as a function of the outer CNT diameter,to assist in determining the energy needed to disperse CNTs. | YANG Kun YI ZiLi JING QingFeng YUE RenLiang JIANG Wei LIN DaoHui | 2013 | Chinese Science Bulletin2013，58，18： | 5 |
| 3 | The effect of oxidation on physicochemical properties and aqueous stabilization of multiwalled carbon nanotubes:comparison of multiple analysis methods显示文摘Surface oxidation can alter physicochemical properties of multiwalled carbon nanotubes(MWCNTs) and influence their aqueous stabilization.Many techniques have been used to characterize the physicochemical properties and aqueous stabilization of MWCNTs.However,the relationship between the change in physicochemical property and the aqueous stabilization of MWCNTs merits more studies,and the multiple characterization techniques have not been well compared.This study systematically and comparatively investigated the effect of oxidation on the physicochemical properties and aqueous stabilization of MWCNTs using multiple analysis methods.Increased surface area,disclosed tube ends,defects on the sidewalls,disruption of the electronic structure,and removal of metal catalysts and amorphous carbon were observed for the oxidized MWCNTs(o-MWCNTs) using the multipoint Brunauer-Emmett-Teller(BET) method,transmission electron microscope observation,Raman spectroscopy,UV-Vis spectroscopy,and thermogravimetric analysis.An oxidation-time-dependent increase in oxygen content of the MWCNTs was verified by the methods of elemental analysis,mass difference calculation,and X-ray photoelectron spectroscopy(XPS).Fourier transform infrared spectroscopy,XPS,and the Boehm titration were employed to study the functionalities on the MWCNT surfaces.Despite the limitations of these techniques,the results indicated that the dramatic increase in carboxyl groups was mainly responsible for the significant increase in oxygen content after the oxidation.The dissociation of the grafted functional groups increased electronegativity of the o-MWCNTs and facilitated the aqueous stabilization of o-MWCNTs through electrostatic repulsions.The oxidation affected the UV-Vis absorbance of MWCNT suspensions.The absorbances at 800 nm of the stabilized MWCNT suspensions had a good correlation with the MWCNT concentrations and could be used to quantify the MWCNT suspensions.The findings of this work are expected to boost the research on carbon nanotubes and their environmental behaviors. | Luqing Zhang Minhao Wang Jing Fang Kun Yang Daohui Lin | 2016 | Science China Chemistry2016，59，11： | 2 |

| 8 | Chlorine substitution-dependent toxicities of polychlorinated biphenyls to the earthworm Eisenia fetida in soil显示文摘Polychlorinated biphenyls(PCBs)with different chlorine substitution patterns often coexist in e-waste-processing sites.However,the single and combined toxicity of PCBs to soil organisms and the influence of chlorine substitution patterns remain largely unknown.Herein,we evaluated the distinct in vivo toxicity of PCB28(a trichlorinated PCB),PCB52(a tetrachlorinated PCB),PCB101(a pentachlorinated PCB),and their mixture to earthworm Eisenia fetida in soil,and looked into the underlining mechanisms in an in vitro test using coelomocytes.After a 28-days exposure,all PCBs(up to 10 mg/kg)were not fatal to earthworms,but could induce intestinal histopathological changes and microbial community alterations in the drilosphere system,along with a significant weight loss.Notably,pentachlorinated PCBs with a low bioaccumulation ability showed greater inhibitory effects on the growth of earthworm than lowly chlorinated PCBs,suggesting that bioaccumulation was not the main determinant of chlorine substitution-dependent toxicity.Furthermore,in vitro assays showed that the highly chlorinated PCBs induced a high-percentage apoptosis of eleocytes in the coelomocytes and significantly activated antioxidant enzymes,indicating that the distinct cellular vulnerability to lowly/highly chlorinated PCBs was the main contributor to the PCBs toxicity.These findings emphasize the specific advantage of using earthworms in the control of lowly chlorinated PCBs in soil due to their high tolerance and accumulation ability. | Jianying Zhang Mengyang He Yaoxuan Liu Lei Zhang Haojie Jiang Daohui Lin | 2023 | Journal of Environmental Sciences2023，，6： | 1 |

| 12 | Toxic effects of nano-TiO_(2)in bivalves——A synthesis of meta-analysis and bibliometric analysis显示文摘Since the beginning of the 21 st century,the increasing production and application of nano-TiO_(2)in consumer products have inevitably led to its release into aquatic systems and therefore caused the exposure of aquatic organisms,resulting in growing environmental concerns.However,the safety of nano-TiO_(2)in aquatic environments has not been systematically assessed,especially in coastal and estuary waters where a large number of filterfeeding animals live.Bivalves are considered around the world to be a unique target group for nanoparticle toxicity,and numerous studies have been conducted to test the toxic effects of nano-TiO_(2)on bivalves.The aim of this review was to systematically summarize and analyze published data concerning the toxicological effects of nano-TiO_(2)in bivalves.In particular,the toxicity of nano-TiO_(2)to the antioxidant system and cell physiology was subjected to meta-analysis to reveal the mechanism of the toxicological effects of nano-TiO_(2)and the factors affecting its toxicological effects.To reveal the cooperation,hot keywords and cocitations in this field,bibliometric analysis was conducted,and the results showed that the toxicological molecular mechanisms of nano-TiO_(2)and the combined effects of nano-TiO_(2)and other environmental factors are two major hot spots.Finally,some perspectives and insights were provided in this review for future research on nano-TiO_(2)toxicology in bivalves. | Zhuoqing Li Menghong Hu Hanting Song Daohui Lin Youji Wang | 2021 | Journal of Environmental Sciences2021，33，6： | 1 |

| 14 | Sorption kinetics of 1,3,5-trinitrobenzene to biochars produced at various temperatures显示文摘Sorption kinetics of organic compounds on biochars is important for understanding the retardation of mobility and bioavailability of organic compounds.Herein,sorption kinetics of 1,3,5-trinitrobenzene on biochars prepared from 200 to 700℃was investigated to explore the sorption process.Loose partition matrix and condensed partition matrix were formed at relatively low and moderate temperatures,respectively.However,biochars produced at relatively high temperatures formed rich pore structures.Therefore,sorption equilibrium time of 1,3,5-trinitrobenzene increased with increasing preparation temperature from 200 to 350℃due to the slower diffusion rate in the more condensed matrix,and then decreased when preparation temperature was higher than 400℃because of the faster adsorption rate in the greater number of pores.Linear positive relationship between matrix diffusion rates of 1,3,5-trinitrobenzene on biochars prepared at 200,250,300,350℃and H/C ratios of biochars was observed,suggesting that the inhibition of partition process was caused by the condensed matrix in biochars.Linear positive relationships between adsorption rates(i.e.,fast outer diffusion rate and slow pore diffusion rate)of 1,3,5-trinitrobenzene on biochars prepared at 400,450,550,700℃and graphite defects of biochars were observed,because the increase of graphite defects of biochars could promote the adsorption by increasing the quantity of fast diffusion channels and sorption sites.This study reveals the underlying mechanisms of sorption kinetics for organic compounds with relatively large size on biochars,which has potential guidance for the application of biochars and prediction of the environmental risks of organic compounds. | Hongxia Zhu Xianyu Liu Yuan Jiang Daohui Lin Kun Yang | 2022 | Biochar2022，4，1： | 1 |

| 17 | Environmental Behaviors and Biological Effects of Engineered Nanomaterials:Important Roles of Interfacial Interactions and Dissolved Organic Matter显示文摘With the fast development of nanotechnology,reactive engineered nanomaterials(ENMs)are increasingly discharged into the environment,where they interact with environmental components and organisms and thus pose potential risks.The interactions-derived formation of nano-environmental and nano-bio interfaces determines environmental behaviors and biological effects of ENMs,and ubiquitous dissolved organic matter(DOM)is bound to impact the interfacial interactions and the resulted environmental risks.Herein,we systematically investigated adsorptive interactions between ENMs and various DOM representatives,and thereby demonstrated the effects of DOM on the aqueous suspension/aggregation,mobility in porous media,adsorption of contaminants,transformation,and biological accumulation and toxicity of ENMs.Overall,we conclude that natural DOM can in general expand environmental distribution of ENMs while limit their toxicity to organisms. | Yanlong Wang Cheng Lei Daohui Lin | 2021 | Chinese Journal of Chemistry2021，39，2： | 1 |

| 19 | Multimedia distribution and health risk assessment of typical organic pollutants in a retired industrial park显示文摘The overall cross-media risk evaluation of organic pollutants in retired industrial parks is insufficiently recognized.In this study,11 semi-volatile organic compounds(SVOCs)and 27 volatile organic compounds(VOCs)were measured in 531 soil and groundwater samples taken from a retired industrial park by coast in Zhejiang Province,China.Total petroleum hydrocarbons(TPHs),Di(2-ethylhexyl)phthalate(DEHP),benzene,and ethylbenzene were identified as the critical pollutants in the soil,while TPHs,1,2-dichloropropane(1,2-DCP),toluene,benzo[a]anthracene(BaA),and benzo[b]fluoranthene(BbF)were identified as critical pollutants in the groundwater for exceeding China national standards.The spatial correlation between the concentrations of organic pollutants in soil and groundwater was explored by employing the Geodetector model.Based on the results of spatial interpolation,high-risk hotspots regarding soil and groundwater pollution were identified.Moreover,the possible harm to human health of the critical pollutants were also under evaluation.Among various critical pollutants,benzene,ethylbenzene,and DEHP in soil,and 1,2-DCP in groundwater,were the main contributors to the overall health risk of multimedia pollution.This study developed a comprehensive approach to assess the risks posed by specific organic toxicants in various environmental media.The findings of this work can serve as a valuable reference for future management strategies in retired industrial parks. | Shijin Wu Zijing Xiang Daohui Lin Lizhong Zhu | 2023 | Frontiers of Environmental Science & Engineering2023，17，11： | 0 |
