2008年5月和8月,在胶州湾养殖区设置9个站位,分别进行水样和沉积物采集,利用5975气相色谱-质谱联用仪(GC/MS)进行多溴联苯醚测定。结果显示,在该水域水体中共检出4种多溴联苯醚单体,总浓度范围为ND～630.8 pg/L,其中BDE-47是主要污染物;沉积物中共检出8种多溴联苯醚单体,总浓度范围为(189.2～1349.7)×10-12。BDE-47、-99是沉积物中主要污染物。该海域多溴联苯醚的分布特征是靠近胶州湾东北岸的9号、8号站最高。另外,大沽河、桃源河入海口附近的1号站相对偏高,呈现出由东、西向中间方向逐渐递减的趋势。总体结果表明:多数站位8月份∑PBDEs含量高,5月份含量低。
In May and August 2008, nine stations were set up in the aquaculture area of Jiaozhou Bay for water samples and sediment collection respectively. Polybrominated diphenyl ethers were determined by GC / MS with 5975 GC / MS. The results showed that a total of four PBBs were detected in the water body of the waters with a total concentration range of ND ~ 630.8 pg / L, of which BDE-47 was the main pollutant; eight PBDEs were detected in the sediments, The concentration range of (189.2 ~ 1349.7) × 10-12. BDE-47, -99 are the major pollutants in sediments. The distribution of polybrominated diphenylethers in this area is the highest at stations 9 and 8 near the northeast bank of Jiaozhou Bay. In addition, station No. 1 near the mouth of the Dagu River and Taoyuan River is relatively high, showing a tendency of gradually decreasing from east to west to the middle. The overall results show that most stations have high ΣPBDEs in August and low levels in May.
