| 1 | Synthesis of a novel ternary HA/Fe-Mn oxides-loaded biochar composite and its application in cadmium(Ⅱ) and arsenic(Ⅴ) adsorption显示文摘Cadmium (Cd) and arsenic (As) are two of the most toxic elements.However,the chemical behaviors of these two elements are different,making it challenging to utilize a single adsorbent with high adsorption capacity for both Cd(Ⅱ) and As(Ⅴ) removal.To solve this problem,we synthesized HA/Fe-Mn oxides-loaded biochar (HFMB),a novel ternary material,to perform this task,wherein scanning electron microscopy (SEM) combined with EDS (SEM-EDS) was used to characterize its morphological and physicochemical properties.The maximum adsorption capacity of HFMB was 67.11 mg/g for Cd(Ⅱ) and 35.59 mg/g for As(Ⅴ),which is much higher compared to pristine biochar (11.06 mg/g,0 mg/g for Cd(Ⅱ) and As(Ⅴ),respectively).The adsorption characteristics were investigated by adsorption kinetics and the effects of the ionic strength and pH of solutions.X-ray photoelectron spectroscopy (XPS) and Fourier-transform infrared spectroscopy (FT-IR) revealed that chelation and deposition were the adsorption mechanisms that bound Cd(Ⅱ) to HFMB,while ligand exchange was the adsorption mechanism that bound As(Ⅴ). | Jianhua Guo Changzhou Yan Zhuanxi Luo Hongda Fang Shugang Hu Yinglan Cao | 2019 | Journal of Environmental Sciences2019，31，11： | 10 |
| 2 | Thallium contamination in agricultural soils and associated potential remediation via biochar utilization显示文摘Thallium(Tl)is an extremely harmful metal that is substantially distributed in the environment.It can threaten human health via consumption of food potentially derived from Tl-contaminated agricultural production.Little information is available on how to utilize biochar to remediate Tl contamination in agricultural soils.More efforts are urgently needed to be devoted to developing effective techniques to empower biochar with high selectivity of Tl in agricultural soils.In this review,we provided comprehensive information on Tl contamination in agricultural soils.We also discussed recent developments and assessed the current status of biochar applications.We briefly reviewed the bridge between biochar preparation technology and utilization wherein further developments can exhibit potential in terms of Tl remediation.Hence,biochar is expected to exhibit excellent Tl remediation performance in contaminated agricultural soils with promising application prospects.The obtained knowledge provides further insights into the remediation of Tl contamination in agricultural soils. | Zhuanxi Luo Alexis Kayiranga Ernest Uwiringiyimana Qinghua Zhang Changzhou Yan Jianhua Guo Baoshan Xing | 2020 | Biochar2020，2，1： | 2 |

| 4 | Insights into the conversion of dissolved organic phosphorus favors algal bloom, arsenate biotransformation and microcystins release of Microcystis aeruginosa显示文摘Little information is available on influences of the conversion of dissolved organic phosphorus(DOP) to inorganic phosphorus(IP) on algal growth and subsequent behaviors of arsenate(As(V)) in Microcystis aeruginosa(M. aeruginosa). In this study, the influences factors on the conversion of three typical DOP types including adenosine-5-triphosphate disodium salt(ATP), β-glycerophosphate sodium(βP) and D-glucose-6-phosphate disodium salt(GP)were investigated under different extracellular polymeric secretions(EPS) ratios from M.aeruginosa, and As(V) levels. Thus, algal growth, As(V) biotransformation and microcystins(MCs) release of M. aeruginosa were explored in the different converted DOP conditions compared with IP. Results showed that the three DOP to IP without EPS addition became in favor of algal growth during their conversion. Compared with IP, M. aeruginosa growth was thus facilitated in the three converted DOP conditions, subsequently resulting in potential algal bloom particularly at arsenic(As) contaminated water environment. Additionally, DOP after conversion could inhibit As accumulation in M. aeruginosa, thus intracellular As accumulation was lower in the converted DOP conditions than that in IP condition. As(V) biotransformation and MCs release in M. aeruginosa was impacted by different converted DOP with their different types. Specifically, DMA concentrations in media and As(III) ratios in algal cells were promoted in converted βP condition, indicating that the observed dissolved organic compositions from βP conversion could enhance As(V) reduction in M. aeruginosa and then accelerate DMA release. The obtained findings can provide better understanding of cyanobacteria blooms and As biotransformation in different DOP as the main phosphorus source. | Xiaoyan Zhang Zhenhong Wang Zhuanxi Luo Yan Chen Xuguang Huang | 2023 | Journal of Environmental Sciences2023，，3： | 1 |

| 10 | Stormwater Runoff Pollution in a Rural Township in the Hilly Area of the Central Sichuan Basin,China显示文摘Stormwater runoff in rural townships has a high potential for water quality impairment but little information is available on strormwater runoff pollution from rural townships.To investigate the characteristics of runoff pollution in a rural township,a catchment(2.32 ha) in Linshan Township,Sichuan,China was selected to examine runoff and quality parameters including precipitation,flow rate,and total nitrogen(TN),dissolved nitrogen(DN),total phosphorus(TP),dissolved phosphorus(DP),particulate phosphorus(PP),chemical oxygen demand(COD) and suspended solid(SS) in 12 rainfall events occurring between June 2006 and July 2007.Results show that the annual pollutant loads were 47.17 kg ha-1 for TN,6.64 kg ha-1 for TP,1186 kg ha-1 for COD,and 4297 kg ha-1 for SS.DN and PP were the main forms of nitrogen and phosphorus in stormwater runoff.TP,COD and SS showed medium mass first flushes,in which nearly 40% of the total pollutant masses were transported by the first 30% of total flow volume.The peak of pollutant concentration appeared before the peak of runoff due to the first flush of accumulative pollutants in impervious areas and drainage ditches.The EMC values of TN,TP,DN and PP were negatively correlated to the maximum rainfall intensity,precipitation,total flow volume,and runoff duration(P<0.05,n=12),while EMC of COD and SS were not related to any rainfall characteristics.The FF30(FF,First Flush) for TN,TP,COD and SS were positively correlated to the maximum rainfall intensity(P<0.05,n=12),and TP was also positively correlated to the average rainfall intensity(P<0.05,n=12),indicating that the magnitude of first flush increased with the rainfall intensity in the Linshan Township. | LUO Zhuanxi WANG Tao GAO Meirong TANG Jialiang ZHU Bo | 2012 | Journal of Mountain Science2012，9，1： | 1 |

| 13 | Insights into thallium adsorption onto the soil,bamboo-derived biochar,and biochar amended soil in Pomelo orchard显示文摘Little information is available on thallium(Tl)adsorption onto biochar amended soil for a relatively long term.In this study,bamboo-derived biochar(BDB),soil in pomelo orchard(SP),and biochar amended soil in pomelo orchard(BSP)were thus used to evaluate the potential remediation of thallium(Tl)using batch-adsorption techniques.Furthermore,we characterized the above-mentioned sorbents’properties related to Tl adsorption to understand Tl’s adsorption mechanisms.The results showed that BDB,SP,and BSP achieved equilibrium adsorption capacity of 96.9,95.43,and 96.76%,respectively,within the initial 15 min.This means that compared to other sorbents,BSP exhibited an efficient sorbent for Tl remediation even when applied in the agricultural field for one year.Multi-layer adsorption played a dominant role in the adsorption of Tl,which was supported by the suitability of Freundlich model for describing the adsorption behavior of Tl onto the selected sorbents.In addition,the pseudo-second kinetic order models strongly fitted Tl’s adsorption onto BDB,SP,and BSP,indicating that the process was accompanied by chemical adsorption.Observed on the surface of BDB by a Fourier Transform Infrared Spectrometer(FTIR)and an X-ray photoelectron spectroscopy(XPS),the presence of O-H groups and PO_(4)^(3−)might promote chemical adsorption of Tl onto BDB.Overall,these findings can provide insights into comprehensively developed bamboo-derived biochar technology to remediate Tl contamination in agricultural soils. | Alexis Kayiranga Zhuanxi Luo Jean Claude Ndayishimiye François Nkinahamira Eric Cyubahiro Theogene Habumugisha Changzhou Yan Jianhua Guo Zhuo Zhen Alexandre Tuyishimire Hildebrand Didier Izabayo | 2021 | Biochar2021，3，3： | 0 |
| 14 | The frontier of microplastics and nanoplastics: Soil health and carbon neutrality显示文摘Microplastics and nanoplastics(MNPs)in soil have drawn increasing concerns about their potential threats to soil ecosystems due to their ubiquitous occurrence and persistence.The interactions of MNPs with soil components,microbial community,plants,and fauna determine their impacts on soil biogeochemical processes and food security.However,they are not largely explored.Further research is also needed to develop reliable and standardized techniques and methods to characterize the relevant MNPs interacting with different types of soil ecosystems and to deeply examine their impacts on soil health,food security,and climate changes.In addition,mitigation protocols and regulation guidelines need to be developed.New findings will provide scientific and technological support for the understanding and management of soil health and carbon neutrality as influenced by MNPs. | Zhuanxi LUO Aoze LI Haiming WANG Baoshan XING | 2023 | Pedosphere2023，33，1： | 0 |
| 15 | Distributive Characteristics of Metallic Nano-particles in China's Urban Water Bodies and their Ecological Risks显示文摘Engineering nano-materials & their impact on human health or environmental security constitute a newly emerging R&D hot spot and a key problem now urgently waiting for its solution in supporting the sustainability of China's nano-science and related technology development. At present, water bodies in Chinese cities have been seriously polluted by metallic nano-particles (MNPs) while related monitoring data are found woefully lacking throughout the country. Based on the above understanding, this article gives a round-up explanation on distributive characteristics of MNPs in the river mouths or water bodies of Chinese cities, their ecological hazards as well as our research in this regard, providing some inspiring ideas and data for control over this scourge. In addition, our exploration probes the discharge traits of MNPs themselves and the mechanism underlying its impact on water pollution. | GAO Yang LUO Zhuanxi XIA Jun | 2012 | Bulletin of the Chinese Academy of Sciences2012，26，1： | 0 |
