摘      要：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 *** 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 *** 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 *** levels decreased concomitantly with increasing distance from the EWR *** 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 ***,the estimated daily intakes of those FRs via soil ingestion were approximately ten times higher for children than *** 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.
