摘要:采集分析了中国东海28个表层沉积物和7个柱状沉积物.结果表明,东海表层沉积物中除BDE-209外∑PBDEs的浓度范围为0.20~2.09ng/g dw,BDE-209的浓度范围为0.57~2.87ng/g dw,在总PBDEs中所占浓度百分比为57.9%~76.7%;接下来分别是BDE-99和BDE-47,所占比例分别为11.7%~21.5%和7.1%~17.4%.表层沉积物中PBDEs分布呈现出(离海岸线)由近及远浓度越来越低的趋势,由北到南浓度上升的趋势.东海柱状沉积物中PBDEs浓度随着深度加深呈现出先上升后下降的趋势,很好的反映出了PBDEs在中国大陆的使用历史和现状.表层沉积物TOC含量在0.54%~0.88%之间,柱状沉积物TOC的含量在0.62%~0.88%之间,而且不管是表层沉积物(R2=0.723,P〈0.01)还是柱状沉积物(R2=0.595,P〈0.01),PBDEs浓度和TOC含量之间有较强的线性关系,表明沉积物中TOC含量是影响PBDEs分布的一个重要因素.
In this study, 28 surface sediment and 7core sediment samples were collected from the East China Sea(ECS) to determine the distribution properties of polybrominated diphenyl ethers(PBDEs). The concentrations of total PBDEs(excepted BDE-209) in surface sediment samples were in the range of 0.20~2.09ng/g dw. Among the detected congeners, BDE-209 was the predominant congener with the corresponding concentration ranging from 0.57~2.87ng/g dw(57.9%~76.7% of total PBDEs), followed by BDE-99 and BDE-47. Moreover, the concentrations of PBDEs decreased with the increase of distance between sampling sites and coastline and increased from the north to south. The distribution trends of PBDEs in core sediment samples from the ECS matched well with the application history and status of PBDEs products in China. The ratios of total organic carbon(TOC) in the surface and core sediment samples were ranged from 0.54%~0.88% and 0.62%~0.88% respectively. And the correlations between TOC and PBDEs in both surface(R2=0.723, P 0.01) and core(R2=0.595, P0.01) sediment samples indicated that TOC might be one of the impact factors for the characteristics of PBDEs distribution in sediment.
