文摘 对珠江三角洲佛山市顺德区容桂镇电器工业区河涌沉积物多溴联苯醚(PBDEs)的含量进行了空间和垂直分布研究.选择该镇中心城区内河涌作为研究河道,根据河涌水流情况选取8个采样点采集沉积物样品.所有样品中均检出PBDEs.各监测点的PBDEs总含量变化范围为62~349 ng.g~(-1)(平均为178 ng.g~(-1)),各采样点的浓度差异较大.其中,十溴联苯醚含量为56~337 ng.g~(-1)(平均为171 ng.g~(-1)),占PBDEs总含量的90%~99%(平均95%).所检测到的部分同系物(如BDE-196、197和203)可能是BDE-209的降解产物.PBDEs的垂直分布模式显示,0~10 cm层面样品的PBDEs浓度为147 ng.g~(-1),30~40 cm层面样品的PBDEs浓度为260 ng.g~(-1),PBDEs在沉积物中的丰度随垂直深度的增加而增加.12种同系物在采自各个深度层样品中的比例基本相同,由十溴工业品来源的BDE-209、208、207和206占总PBDEs的94%,而五溴和八溴所占比例较低.由此可见,该地区普遍存在PBDEs污染,其中十溴联苯醚是最主要污染物,这可能与十溴工业品是电器工业主要使用的阻燃材料相关.
其他语种文摘 Polybrominated diphenyl ethers(PBDEs) were determined in sediment collected from a river in a typical electrical equipment industrial area,Ronggui,Foshan.Eight samples were collected from river sediment.The results indicated that PBDEs were presented in all samples.Spatial trends showed that the concentrations of PBDEs in all sediment samples were ranged from 62 ng·g~(-1) to 349 ng·g~(-1),with an average of 178 ng·g~(-1).The predominant congener was BDE-209(90%-99%),which ranged from 56-337 ng·g~(-1),with an average of 171 ng·g~(-1).Some of congeners such as BDE-196,197 and 203 may be were the degradation product of BDE-209.Vertically,the concentrations of PBDEs were increased with the depth,whereas the concentrations were 147 ng·g~(-1) in layer 0-10 cm and 260 ng·g~(-1) in layer 30-40 cm,respectively.Distribution profile of PBDEs in vertical direction was similar in different depths.The commercial deca-BDE(94%),which contained BDE-209,208,207 and 206,was the dominate pollutant with minor contributions from penta-and octa-BDEs.The results suggested that this area was polluted by PBDEs and BDE-209 was the most dominate congener,which is related with the manufacturing activities for electrical equipment..
