The levels and distribution of tris-(2,3-dibromopropyl) isocyanurate (TBC) and hexabromocyclododecanes (HBCDs) of surface sediments in the Yellow River Delta wetland had been investigated. The concentrations of TBC and Sigma HBCDs ranged from 0.20 to 29.03 ng.g(-1) dw and below limits of detections (LODs) to 20.25 ng.g(-1) dw. The average composition profile of three HBCDs isomers were 10.1%, 6.1% and 83.8% for alpha-, beta- and gamma-HBCD, respectively. Moreover, correlation analysis indicated there are similar sources among three isomers and positive correlations between total organic carbon (TOC) content and concentrations of TBC and HBCDs. The mass inventory of TBC,alpha-, beta-, gamma-HBCD, Sigma HBCDs in surface sediments of Yellow River Delta wetland were estimated about 725.50, 72.76, 44.29, 54834, 66539 kg. Therefore, further investigations on potential human health and environmental risk assessments of TBC and HBCDs were needed. (C) 2016 Elsevier Ltd. All rights reserved.
