目的：调查珠江三角洲地区鱼、鸡肉和畜肉中毒杀芬污染水平及其单体分布特征。方法于2010年10月至2011年6月，采用非概率抽样方法中的立意抽样方法，采集广东省惠州、广州、东莞、江门市的鱼、鸡肉和畜肉食品样品共计60份，采用同位素稀释－高分辨气相色谱／高分辨双聚焦磁式质谱联用方法（ ID－HRGC／HRMS），对3种指示性毒杀芬单体Parlar 26、Parlar 50和Parlar 62进行定性定量分析，并对污染情况和特征进行比较分析。结果鱼类、鸡肉和畜肉中毒杀芬的M分别为12．87、5．8、1．89 ng／kg（本文内均为全重），差异有统计学意义（H＝14．29，P＝0．001）；海鱼中毒杀芬含量（M ＝32．07 ng／kg）高于淡水鱼（M ＝10．63 ng／kg）（Z ＝－2．52，P ＝0．012）。鱼类中Parlar 50、Parlar 26为主要特征性污染物，分别占毒杀芬总浓度的44％（9．91／22．60，ng／kg）、39％（8．89／22．60，ng／kg）；鸡肉中以Parlar 62、Parlar 26为主，分别占42％（5．03／11．90，ng／kg）和38％（4．58／11．90，ng／kg）；畜肉中以Parlar 26和Parlar 62为优势单体，分别占57％（3．45／6．08，ng／kg）、26％（1．58／6．08，ng／kg）。结论珠江三角洲地区3类动物性食品毒杀芬处于较低水平，远低于欧盟食品安全局（ EFSA）所规定的动物性食品中0．1 mg／kg的限量标准。3类动物性食品毒杀芬单体特征不同，反映了不同种属动物富集此类污染物的生物学差异。

Objective To explore the present contamination status and profile of toxaphene in fish, chicken and meat samples in Pearl River Delta area.Methods Totally 60 independent samples including fish,chicken,meat were collected from Huizhou,Guangzhou,Dongguan,Jiangmen of Pearl River Delta area in Guangdong by purposive sampling from Oct 2010 to Jun 2011.Toxaphene monomer Parlar26,Parlar50 and Parlar62 levels in three various categories of foods were quantitatively and qualitatively analyzed referencing international authoritative standard methods by utilizing isotope dilution high-resolution gas chromatography/high-resolution double-focusing magnetic mass spectrometry ( HRGC-HRMS ) .The levels of pollution and characteristics were compared.Results The concentration of toxaphene median(M) in fish,chicken and meat were 12.87,5.8 and 1.89 ng/kg(gross weight),respectively and the difference was significant(H=14.29,P=0.001).The toxaphene level in seafish(M=32.07 ng/kg)was significantly higher than that in freshwater fish(M=10.63 ng/kg,Z=-2.52,P=0.012).The profile analysis showed that Parlar50 and Parlar26 were the predominant characteristic monomers in fish,which contributed about 44%(9.91/22.60, ng/kg) and 39%(8.89/22.60, ng/kg) to total concentration,and Parlar62 and Parlar26 were the two predominant congeners in poultry products,the two congeners accounted for 42%(5.03/11.90, ng/kg) and 38%(4.58/11.90, ng/kg).Furthermore Parlar26 and Parlar62 made up about 57%(3.45/6.08, ng/kg) and 26% ( 1.58/6.08, ng/kg ) of total concentration in livestock meat respectively.Conclusion Toxaphene levels in all tested food samples are far lower than the limited standard stipulated by the European Food Safety Authority(EFSA) in 2002,which was 0.1 mg/kg.The congener characteristic difference in the three categories food indicated that the different enrichment ability in Toxaphene in different animal species.
