摘要
为了解短链氯化石蜡(SCCPs)在我国海域的污染现状,于2009年采集了渤海辽东湾海域的浮游动物、8种底栖动物(虾、蟹、蛤、扇贝和螺)和6种鱼类,采用高分辨气相色谱/电子捕获负离子化-低分辨质谱(HRGC/ECNI-LRMS)分析了其中的SCCPs.结果表明,渤海辽东湾海域水生动物体中SCCPs的含量变化范围为0.66—20.32μg.g-1dw(干重).采集的15种水生动物样品中SCCPs以C10-SCCPs和C11-SCCPs为主,C13-SCCPs含量最低,并且低氯取代(五氯和六氯)的C10-SCCPs和C11-SCCPs在绝大多数生物体内累积量较高.
In order to know the pollution status of short-chain chlorinated paraffins(SCCPs) in China seas,organism samples including plankton,8 kinds of benthic organism(shrimp,crab,clam,scallop,and trumpet shell) and 6 kinds of fish were collected from the sea area of Liaodong Bay in 2009.SCCPs in these organism samples were analyzed using gas chromatography/electron capture negative chemical ionization low-resolution mass spectrometry(HRGC/ECNI-LRMS).The total concentrations of SCCPs in these organism samples were determined to be in the range of 0.66—20.32 μg · g-1 dw.C10-SCCPs and C11-SCCPs predominated over the SCCPs compounds in 15 kinds of organism samples,and the relative concentration of C13-SCCPs was lowest.Meanwhile,the accumulative levels of lower chlorinated(penta-and hexa-chlorinited) C10-SCCPs and C11-SCCPs in most of collected organism samples were found to be higher.
