采集武汉郊区9只喜鹊，分析喜鹊肌肉中的卤代有机污染物，如滴滴涕、多氯联苯、多溴联苯醚、十溴二苯乙烷、得克隆及六溴环十二烷的含量.分析结果表明DDTs、PCBs、PBDEs、DBDPE、DPs和HBCDs的脂肪归一化浓度范围分别为610~15000 ng/g、25~500 ng/g、12~2900 ng/g、0.18~820 ng/g、1.7~15 ng/g和nd(低于检测限)~14 ng/g.DDTs仍是主要的污染物，占总卤代有机污染物的90%以上；其次为PCB和PBDEs.这一结果表明有机氯农药、多氯联苯等这些传统的持久性有机污染物仍是采样区域的主要污染物.但新型污染物如DBDPE的污染也应引起重视.PCBs主要以高氯代单体为主，显示其污染源主要来自高氯代PCB工业品.PBDE存在两种明显不同的组成模式，可能与鸟采食区域和食物来源有关.DPs显示出一定的反式富集特征，这与水鸟的顺式富集特点完全不同.①
採集武漢郊區9隻喜鵲，分析喜鵲肌肉中的滷代有機汙染物，如滴滴涕、多氯聯苯、多溴聯苯醚、十溴二苯乙烷、得剋隆及六溴環十二烷的含量.分析結果錶明DDTs、PCBs、PBDEs、DBDPE、DPs和HBCDs的脂肪歸一化濃度範圍分彆為610~15000 ng/g、25~500 ng/g、12~2900 ng/g、0.18~820 ng/g、1.7~15 ng/g和nd(低于檢測限)~14 ng/g.DDTs仍是主要的汙染物，佔總滷代有機汙染物的90%以上；其次為PCB和PBDEs.這一結果錶明有機氯農藥、多氯聯苯等這些傳統的持久性有機汙染物仍是採樣區域的主要汙染物.但新型汙染物如DBDPE的汙染也應引起重視.PCBs主要以高氯代單體為主，顯示其汙染源主要來自高氯代PCB工業品.PBDE存在兩種明顯不同的組成模式，可能與鳥採食區域和食物來源有關.DPs顯示齣一定的反式富集特徵，這與水鳥的順式富集特點完全不同.①

Total nine common magpies (Pica pica) were collected from suburban of Wuhan City in September 2010 and organohalogen contaminations including dichlorodiphenyl trichloroethane and its metabolites (DDTs), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), decabromodiphenylethane (DBDPE),dechlorane plus (DPs) and hexabromocyclododecanes (HBCDs) were determined.The concentrations of DDTs、PCBs、PBDEs、DBDPE、DPs and HBCD ranged from 610 15 000 ng/g、25 500 ng/g、12 2 900 ng/g、0.18 820 ng/g、1.7 15 ng/g and nd 14 ng/g lipid,respectively. DDTs were the predominant pollutant accounting for more than 90% of total organohalogen congaminations,followed by PCBs and PBDEs. This result indicated that organochlorine pesticides,polychlorinated biphenyls etc,these legacy contaminants were still the main environmental concerns in the study area. However ,more attention should be pay for the pollution of DBDPE. Highly chlorinated PCBs technical mixture might be the main source of PCBs in the study area. Two PBDE congener profiles were observed in the common magpie,which could be attributed to different diet source of common magpie. A selective accumulation of anti-DPs was found in common magpie,which was different from that in aquatic birds.
