| 1 | Occurrence of emerging flame retardants from e-waste recycling activities in the northern part of Vietnam显示文摘This study investigated the contamination status of 21 emerging flame retardants(FRs)in soils(n=32)and river sediments(n=8)from an e-waste recycling(EWR)site in the northern part of Vietnam.Among analyzed FRs,higher levels of decabromodiphenyl ethane(DBDPE)(NDe4200 ng/g dw),1,2-bis-(2,4,6-tribromophenoxy)ethane(BTBPE)(NDe350 ng/g dw)and Dechlorane Plus isomers(DPs)(NDe65 ng/g dw)were found in soils near EWR workshops and open burning places.The highest concentrations of DBDPE(20 ng/g dw),BTBPE(5.7 ng/g dw)and DPs(6.7 ng/g dw)were also detected in sediments collected from the middle of the EWR site.The levels decreased concomitantly with increasing distance from the EWR site.These results indicate that these FRs were released to the surrounding environment from improper recycling activities,such as manual dismantling of devices and open burning of e-wastes.Moreover,the estimated daily intakes of those FRs via soil ingestion were approximately ten times higher for children than adults.To our knowledge,this is a first comprehensive study on characterization of soil and sediment contamination by a series of emerging FRs at an EWR site in Vietnam. | Masayuki Someya Go Suzuki Alin C.Ionas Nguyen Minh Tue Fuchao Xu Hidenori Matsukami Adrian Covaci Le Huu Tuyen Pham Hung Viet Shin Takahashi Shinsuke Tanabe Hidetaka Takigami | 2016 | Emerging Contaminants2016，2，2： | 5 |
| 2 | Satellite Communications Integration with Terrestrial Networks显示文摘In this paper we evaluate the feasibility of seamless and efficient integration of terrestrial communication systems with satellite networks. This aspect is considered by standardisation bodies such as ETSI [1], 5 G-PPP [2] and 3 GPP [3]. A comprehensive system is designed and implemented in an emulation prototype, including standard 3 GPP LTE core network functionality [4] with its different layers: networking, data forwarding, control, management and monitoring and is validated through performance measurements. This work is a technical feasibility study of extending terrestrial communication systems with satellite networks as backhaul, increasing the energy efficiency, network robustness during natural disasters as well as being an alternative for peak-time data forwarding of the terrestrial communication services. Due to its global coverage property, terrestrial-satellite integration provides an obvious extension of communication services towards isolated and remote areas and an alternative for rural or highly distributed/highly mobile enterprise networks. | Adam Kapovits Marius-lulian Corici Ilie-Daniel Gheorghe-Pop Anastasius Gavras Frank Burkhardt Thomas Schlichter Stefan Covaci | 2018 | China Communications2018，15，8： | 4 |
| 3 | Development of an analytical method based on solid-phase extraction and LC-MS/MS for the monitoring of current-use pesticides and their metabolites in human urine显示文摘Pyrethroids,organophosphorus pesticides and fipronil have been listed as priority chemicals in human biomonitoring studies because of their wide use and potential health effects in humans.The determination of 13 pesticides,including pyrethroids(deltamethrin,cypermethrin,permethrin,cyfluthrin,bifenthrin),organophosphorus(chlorpyrifos,chlorpyrifosmethyl,and malathion),fipronil,neonicotinoids(imidacloprid,acetamiprid and thiacloprid)and triazole(prothioconazole),together with 13 corresponding metabolites in human urine samples was achieved by solid-phase extraction and analysis by liquid chromatography coupled to tandem mass spectrometry.All targeted compounds,except malathion dicarboxylic acid,were measured with a mean within-accuracy(n=5)of 71%–114%(RSD:1%–14%)and between-run(n=15)accuracy of 80%–118%(RSD:2%–14%).Limits of quantitation of the targeted analytes ranged from 0.1 to 16 pg/m L.The detection result of urine samples from 25 volunteers indicated that the detection frequencies of 3,5,6-trichloro-2-pyridinol(median:448 pg/m L),6-chloropyridine-3-carboxylic acid(median:193 pg/m L),2-methyl-3-phenylbenzoic acid(median:181 pg/m L),3-phenoxybenzoic acid(median:99 pg/m L),2-isopropyl-6-methyl-4-pyrimidinol(median:77 pg/m L),cyfluthrin(median:59 pg/m L),cis-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylic acid(cis-DCCA,median:53 pg/m L),trans-DCCA(median:25 pg/m L),prothioconazole(median:21 pg/m L),imidacloprid(median:7 pg/m L),and prothioconazole-desthio(median:1 pg/m L)were>50%.The obtained results show that the validated method is suitable for the human biomonitoring of these currentuse pesticides and their metabolites. | Beibei Gao Giulia Poma Govindan Malarvannan Catalina Dumitrascu Michiel Bastiaensen Minghua Wang Adrian Covaci | 2022 | Journal of Environmental Sciences2022，34，1： | 3 |
