The concentration and distribution of tris-(2,3-dibromopropyl) isocyanurate (TBC) and the three isomers of hexabromocyclododecane (HBCDs) were analyzed in the sediment of Jiaozhou Bay wetland in China. The concentrations of TBC and the three isomers of HBCDs (alpha-HBCD, beta-HBCD, gamma-HBCD) were in the ranges of 1.20 to 8.76,1.03 to 5.69,1.13 to 5.46, and 1.18 to 15.04 ng.g(-1) dw (dry weight), respectively. gamma-HBCD was the predominant congener with an average proportion of 52.42% of Sigma HBCDs, average inventory of HBCDs was about 93.53 ng.cm(-2). Depending on the function of wetland, the concentration of HBCDs tended to decrease as the distance to the Xiaojianxi refuse landfill increased. Compared with previous research studies, the concentration of TBC and HBCDs in the Jiaozhou Bay wetland was at a relatively high level. Therefore, more attention should be paid to TBC and HBCDs on account of their persistent impact on human health and the environment. (C) 2016 Elsevier Ltd. All rights reserved.
