| 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 | Analysis of monomeric and oligomeric organophosphorus flame retardants in fish muscle tissues using liquid chromatographyeelectrospray ionization tandem mass spectrometry:Application to Nile tilapia(Oreochromis niloticus)from an e-waste processing area in northern Vietnam显示文摘Using electrospray ionization tandem mass spectrometry combined with liquid chromatography(LC),a novel analytical method was developed to quantify eight monomeric organophosphorus flame retardants(m-PFRs)and three oligomeric organophosphorus flame retardants(o-PFRs)in fish muscle samples.The optimization and validation experiments indicate that the developed method can determine accurately the concentrations of analytes in fish muscle samples.The recoveries of analytes in fish muscle samples were in the range of 74-105%.The coefficients of variation of the concentrations of analytes in fish muscle samples were 0.6-8.9%.The concentrations of analytes in procedural blanks were below the limit of quantification(LOQ)values.Furthermore,the developed method was applied to the analysis of m-PFRs and o-PFRs in the muscle samples of tilapias collected from an electronic waste(ewaste)processing area in northern Vietnam.The concentrations of m-PFRs such as tris(2-chloroethyl)phosphate(TCEP),tris(2-chloroisopropyl)phosphate(TCIPP),and triphenyl phosphate(TPHP)were dominant among the investigated m-PFRs.The respective concentrations of TCEP,TCIPP,and TPHP were up to 160,300,and 230 ng g^-1 lipid weight,respectively,whereas those of o-PFRs were up to 10 ng g^-1 lipid weight.The results of this study indicate lower accumulation potential of o-PFRs compared with m-PFRs for the first time. | Hidenori Matsukami Go Suzuki Nguyen Minh Tue Le Huu Tuyen Pham Hung Viet Shin Takahashi Shinsuke Tanabe Hidetaka Takigami | 2016 | Emerging Contaminants2016，2，2： | 5 |

| 4 | Comprehensive evaluation of dioxins and dioxin-like compounds in surface soils and river sediments from e-waste-processing sites in a village in northern Vietnam:Heading towards the environmentally sound management of e-waste显示文摘The management of electronic waste(e-waste),which can be a source of both useful materials and toxic substances,depending on the processing method,is important for promoting material cycling.In this study,we used the dioxin-responsive chemical-activated luciferase gene expression(DR-CALUX)assay combined with gas chromatographyehigh-resolution mass spectrometry to evaluate the levels of dioxin-like compounds in surface soils and river sediments collected in and around an e-waste-processing village in northern Vietnam.The WHO-TEQs(Toxic equivalents)of polychlorinated dibenzo-p-dioxins and dibenzofurans(PCDD/Fs),coplanar polychlorinated biphenyls(Co-PCBs),and polybrominated dibenzo-pdioxins and dibenzofurans(PBDD/Fs)in soils collected in January 2012 ranged from 0.29 to 310 pg/g(median 2.9 pg/g,n=32),and the WHO-TEQs in sediments ranged from 0.96 to 58 pg/g(median 4.4 pg/g,n=8).Dioxin-like activities(CALUX-TEQs[2,3,7,8-TCDD equivalent])in soils collected in January 2012,2013,and 2014 ranged from<30 to 4300 pg/g(median<30 pg/g,n=96),and the activities in sediments ranged from<30 to 4000 pg/g(median 33 pg/g,n=24).Dioxin-like compounds accumulated in samples collected around e-waste-processing areas such as open-burning sites and e-waste-processing workshops,and the compounds may be transported from their sources to surrounding areas over the course of several years.Some of the CALUX-TEQs,but not WHO-TEQs,values were higher than the maximum acceptable WHO-TEQs promulgated by various authorities,indicating that all dioxin-like compounds should be evaluated in samples collected from e-waste-processing areas.Our findings suggest that open burning and open storage of e-waste should be prohibited and that wastewater treatment should be implemented at each workshop to reduce contamination by dioxin-like compounds from e-waste. | Go Suzuki Masayuki Someya Hidenori Matsukami Nguyen Minh Tue Natsuyo Uchida Le Huu Tuyen Pham Hung Viet Shin Takahashi Shinsuke Tanabe Abraham Brouwer Hidetaka Takigami | 2016 | Emerging Contaminants2016，2，2： | 1 |
