Objective To develop a method for the simultaneous determination of 18 kinds of polychlorinated biphenyls (PCBs) in pork by isotope dilution-gas chromatography-high resolution magnetic mass spectrometry. Methods The optimal conditions of the accelerated solvent extractor and fully automated clean-up apparatus were determined by optimizing the extraction rate of the target substances using an accelerated solvent extractor and a fully automated clean-up instrument combined with isotope dilution method coupled with gas chromatography-high resolution magnetic mass spectrometry. A 4-factor, 3-level orthogonal test was designed using the extraction temperature, static extraction time and the number of cycles as the main factors to investigate the effect of the accelerated solvent extractor on the extraction rate of the fat content of the samples. The effects of the accelerated solvent extractor on the extraction rate of fat content of the samples were investigated. Results The linear relationships of the indicator PCBs (PCB28, PCBB52, PCB101, PCB118, PCB138, PCB153, PCB180) was good in the range of 0.5 to 200.0 pg/µL, and the linear range of the DL-PCBs (PCB77, PCB81, PCB105, PCB114, PCB123, PCB126, PCB156, PCB157, PCB167, PCB169, PCB189) had a good linear relationship in the range of 0.10 to 40.0 pg/µL, the correlation coefficients were all above 0.999. The limits of detection were in the range of 0.001-0.004 pg/g, and the limits of quantitation were in the range of 0.004-0.012 pg/g; the accuracy and precision of the fishmeal matrix standard reference material were tested by this study, and the PCBs levels were within the range with the relative standard deviations of 1.0%-7.5%. For the determination of actual samples of pork, and the contamination levels of PCBs in 18 kinds of were 1978.9-2530.8 pg/g fat. Conclusion This study is efficient, accurate, sensitive and suitable for the determination of 18 kinds of PCBs in pork.

Objective To develop a method for the simultaneous determination of 18 kinds of polychlorinated biphenyls (PCBs) in pork by isotope dilution-gas chromatography-high resolution magnetic mass spectrometry. Methods The optimal conditions of the accelerated solvent extractor and fully automated clean-up apparatus were determined by optimizing the extraction rate of the target substances using an accelerated solvent extractor and a fully automated clean-up instrument combined with isotope dilution method coupled with gas chromatography-high resolution magnetic mass spectrometry. A 4-factor, 3-level orthogonal test was designed using the extraction temperature, static extraction time and the number of cycles as the main factors to investigate the effect of the accelerated solvent extractor on the extraction rate of the fat content of the samples.

多氯联苯(polychlorinated biphenyls, PCBs)是联苯上的氢原子被氯原子取代后生成的一类氯代芳香族化合物, 根据氯原子取代数目及位置的不同, 有209种同系物, 具有持久性、高毒性和生物累积性, 是《斯德哥尔摩公约》首批必须优先控制的持久性有机污染物之一[1]。PCBs曾被广泛应用于各种行业, 包括电容器和变压器的绝缘流体、增塑剂、润滑剂及阻燃剂等[2-3]。20世纪80年代以来, 在世界范围内停止生产和使用PCBs[4], 但它们仍能在各种环境、食品和人体样品中检出[5-8]。根据毒理学性质, PCBs可分为2类。12种非邻位或平面取代的PCBs (PCB77、PCB81、PCB105、PCB114、PCB118、PCB123、PCB126、PCB156、PCB157、PCB167、PCB169、PCB189)具有类似二噁英的特性, 被定义为二噁英样PCBs (dioxin-like PCBs, DL-PCBs)。其他的PCBs不具有二噁英的毒性特征, 被称为非二噁英样PCBs (non-dioxin-like PCBs, NDL-PCBs), 其中有6种非二噁英样PCBs (PCB28、PCB52、PCB101、PCB138、PCB153、PCB180)的总和约占NDL-PCBs的50%以上, 被认为是指示性PCBs, 常用来评估PCBs的污染状况。因此, 这18种PCBs是食品中PCBs污染的重要监测指标。
人体可经由多种途径摄入PCBs, 普遍认为膳食摄入是普通人群暴露于PCBs的主要方式, 占人体总摄入量的90%以上[9-10], 其中动物源性食品是主要来源[11-12]。肉类及水产品是最易受到污染的食品, 据调查, 人类通过食物摄入的PCBs主要集中在鱼类, 其次是肉类(牛肉、猪肉和家禽)、乳制品和鸡蛋。在我国, 肉类是消费量最大的动物源性食品[13-14], 尤其是猪肉, 它是最主要的肉类食品[15-16]。因此, 建立一种快速、准确、高灵敏的方法来监测和评估猪肉中PCBs的污染水平显得尤为重要。
猪肉样品中PCBs的检测分析面临基质复杂、脂肪含量高和浓度水平较低等问题。目前对猪肉中PCBs的研究相对较少, 从提取、净化和检测进行描述。主要的提取方法有索氏提取[17]和加速溶剂萃取(accelerated solvent extractor, ASE)[18], 索氏提取是一种十分经典的提取方法, 回收率高, 但溶剂消耗量大、萃取时间长。ASE是近些年发展起来的一种自动化样品提取方法, 具有溶剂用量少、提取快速高效的特点[19], 并且已经被多个标准纳入。另外, 一些文献还报道使用超声辅助萃取(ultrasound-assisted extraction, UAE)[20]、微波辅助萃取(microwave-assisted extraction, MAE)[21]、QuEChERS方法[22-23]等, 这些方法虽然简便快速、经济实惠, 但对于回收率会有影响[24-25]
猪肉样品的净化过程包含除脂和净化分离, 常用的除脂方法有浓硫酸[26]和凝胶渗透色谱法(gel permeation chromatography, GPC)[27], 而净化分离通常使用层析净化柱和固相萃取柱[28]。另外, 随着仪器技术的发展, 全自动净化系统也越来越受欢迎。用于检测PCBs的仪器包括气相色谱-电子捕获检测器(gas chromatography-electron capture detector, GC-ECD)[29-30]、气相色谱-质谱法(gas chromatography-mass spectrometry, GC-MS)[31-33]、气相色谱-三重四极杆质谱法(gas chromatography-triple quadrupole mass spectrometry, GC-MS/MS)和气相色谱-高分辨磁质谱法(gas chromatography-high resolution magnetic mass spectrometry, GC-HRMS)[34-35]。尽管GC-MS与GC-ECD虽然操作简单, 但容易受到基质的干扰[36]
猪肉样品基质复杂且脂肪含量高, 传统的提取方式虽然简单, 但存在萃取时间长, 溶剂消耗大, 提取不完全等问题。ASE是一种环境友好型技术, 产生少量废液、降低成本和时间, 同时萃取效率高。猪肉样品常用的净化方法不仅费时(例如用硫酸净化时会重复操作2~3次)、溶剂使用量大、成本高, 而且回收率低。全自动净化系统(DEX Tech 16)不仅能解放双手, 保护实验人员, 而且溶剂消耗量少, 净化时间短、实验效率高。气相色谱法易受基质干扰, GC-MS虽然准确度和灵敏度高, 但因为猪肉基质中PCBs含量低, 检测干扰大, 而GC-HRMS能够实现痕量级检测, 灵敏度高, 检出限低。
因此, 本研究基于猪肉样品基质复杂且PCBs的含量水平较低[37-38], 参照EPA1668A[39]的方法采用GC-HRMS进行定性定量分析, 并结合加速溶剂萃取仪和全自动净化仪对样品进行提取和净化, 建立了一种方法来检测猪肉中18种PCBs, 为猪肉中PCBs的分析检测提供参考。

ASE具有溶剂使用量少、快速、基质影响小等优点。萃取温度、静态萃取时间和萃取循环次数是影响其提取效率的关键因素, 本研究对这3个条件进行优化, 通过目标物的回收率, 确定最优的萃取温度、静态萃取时间和萃取循环次数。
(1)萃取温度的考察
本研究探讨在不同的萃取温度下, 比较目标化合物的提取效率。设定ASE的萃取温度在100、110、120、130、140、150 ℃时, 目标化合物回收率的变化趋势。见图1, 发现18种PCBs中, PCB28在100 ℃到150 ℃内回收率总体变化不大; PCB52、PCB101和PCB180在110 ℃时回收率达到最大; PCB77、PCB81、PCB126和PCB169在120 ℃时回收率达到最大; 其余的均在130 ℃时回收率达到最大值。
18种PCBs的平均回收率随萃取温度的变化如图2所示。在100 ℃到130 ℃内随着萃取温度的升高逐渐增加, 超过130 ℃后, 平均回收率降低。原因可能是温度的升高降低萃取剂的黏度, 提高PCBs在萃取溶剂中的溶解度, 使PCBs的扩散速率增大, 提取效果变好[35]; 然而, 温度过高, 目标物即PCBs会发生降解, 回收率降低[40]。所以本研究拟采取萃取温度130 ℃最佳。
(2)静态萃取时间的考察
本研究研究了不同静态萃取时间对目标化合物提取效率的影响。设定ASE的静态萃取时间在4、6、8、10 min时, 目标化合物回收率的差异。见图3, 发现18种PCBs中, PCB118在4 min时回收率达到最大; PCB81、PCB138和PCB189在6 min时回收率达到最大; 其余的均在8 min时回收率达到最大值。
18种PCBs的平均回收率随静态萃取时间的变化如图4所示。在4 min到8 min内随着静态萃取时间的升高逐渐增加, 超过8 min后, 平均回收率不再增长。原因可能是PCBs保留在基质孔隙或者其他结构中, 增加静态萃取时间可以使PCBs扩散到萃取溶剂中, 回收率增加。所以本研究拟采取静态萃取时间8 min最佳。
(3)循环次数的考察
本研究探讨在不同的循环次数下, 目标化合物的提取效率。设定ASE的循环次数在2、3、4和5次时, 目标化合物回收率的变化趋势。见图5, 发现18种PCBs中, PCB28、PCB101和PCB118在循环次数为3次时回收率达到最大; PCB114、PCB156、PCB157和PCB167在2次时回收率达到最大; 其余的均在4次时时回收率达到最大值。
18种PCBs的平均回收率随循环次数的变化如图6所示。平均回收率在2次到4次内随着循环次数的升高逐渐增加, 超过4次后, 平均回收率不再升高。所以本研究拟采取循环次数4次最佳。
综上所述, 因此, 通过ASE提取的萃取温度、静态萃取时间、循环次数这3个因素对目标物回收率影响的探究, ASE的萃取条件在萃取温度130 ºC, 静态萃取时间8 min, 循环次数4次时最佳。
脂肪含量也是ASE 提取的一个重要指标, 目前常用来评估的欧盟法规(No.1259/2011)中规定的猪肉中PCBs的限量值就是以脂肪计重的, 所以脂肪提取率不佳会直接影响结果的准确性。本研究用萃取温度、静态萃取时间和循环次数作为主要的影响因素, 探讨对样品脂肪含量提取率的影响。因此采用正交试验进行进一步优化, 设计4因素3水平即L9(34)的正交试验见表2
使用Minitab软件设计9组实验, 并对结果进行了分析, 以脂肪含量作为指标。
表3可知, 由k值可以看出最佳的水平组合A2B3C3, 即: 萃取温度130 ºC, 静态萃取时间8 min, 循环次数4次。
对实验结果进行方差分析, 如表4所示。萃取温度(F=12.815)、静态萃取时间(F=14.668)和循环次数(F=11.703), 说明3种因素对脂肪量的提取效率影响的主次关系为: 静态萃取时间>萃取温度>循环次数。
本研究通过探讨萃取条件对脂肪提取量的影响, 在正交试验结果中发现ASE的最佳萃取条件为萃取温度130 ºC, 静态萃取时间8 min, 循环次数4次。
综上所述, 因为猪肉样品的脂肪提取率会直接影响PCBs检测结果的响应准确性, 本研究为获得较高脂肪提取率, 同时节约时间和溶剂, 通过对猪肉样品中目标物提取率优化和脂肪含量提取率的优化, ASE的萃取条件为萃取温度130 ºC, 静态萃取时间8 min, 循环次数4次。
全自动净化系统(DEX Tech 16)具有净化时间短、实验效率高等优点, 不同的洗脱溶剂和洗脱溶剂体积会影响目标物的洗脱, 通过对18种PCBs回收率进行比较, 可以确定最优的洗脱溶剂配比和洗脱溶剂体积。
将洗脱溶剂配比(正己烷:二氯甲烷, V:V, 下同)设定为正己烷(100%)、4:1、1:1、1:4和二氯甲烷(100%), 洗脱溶剂体积设定为30 mL。结果如图7所示。
图7可知, 18种PCBs各自的平均回收率在洗脱溶剂配比(正己烷/二氯甲烷)为1:4和二氯甲烷(100%)时在数值上达到最大(52%~100%)且趋于稳定, 所以本研究洗脱溶剂配比(正己烷/二氯甲烷)为1:4时, 是DEX Tech 16最佳溶剂配比。
同理将洗脱溶剂配比(正己烷/二氯甲烷)设定为4:1, 洗脱溶剂体积(正己烷/二氯甲烷)设定为10、20、30、36、40 mL。结果如图8所示。
图8可知, 18种PCBs各自的平均回收率在洗脱溶剂体积(正己烷/二氯甲烷)为20 mL时在数值上达到最大(53%~89%), 在30、36、40 mL时, 与在20 mL时相差很少且趋于稳定, 因考虑到实验过程要产生少量废液、节约溶剂、降低成本和时间, 提高效率, 所以本研究选择洗脱溶剂体积20 mL为DEX Tech 16最佳洗脱溶剂体积。
综上所述, 本研究的全自动净化仪的净化条件为洗脱溶剂配比(正己烷/二氯甲烷)1:4, 洗脱溶剂体积20 mL。
将PCBs系列标准溶液进样, 其中 PCB28、PCB52、PCB101、PCB118、PCB138、PCB153、PCB180的质量浓度为0.5、2.5、10.0、50.0、200.0 pg/µL; PCB77、PCB81、PCB105、PCB114、PCB123、PCB126、PCB156、PCB157、PCB167、PCB169、PCB189的质量浓度为0.10、0.50、2.0、10.0、40.0 pg/µL, 采用同位素内标定量法, 以标准溶液中目标化合物浓度比作为横坐标, 目标化合物和定量内标化合物峰面积比作为纵坐标绘制标准曲线, 得到的线性方程及其相关系数如表5所示。在0.5~200.0 pg/µL的范围内, PCB28、PCB52、PCB101、PCB118、PCB138、PCB153、PCB180的线性范围良好; 在0.10~40.0 pg/µL的范围内, PCB77、PCB81、PCB105、PCB114、PCB123、PCB126、PCB156、PCB157、PCB167、PCB169、PCB189的线性范围良好, 相关系数均在0.999以上。图9为标准系列的CS4的总离子流色谱图。
本研究使用信噪比S/N≥3对应的浓度确定检出限, 以S/N≥10对应的浓度确定定量限, 如表5所示, 检出限的范围为0.001~0.004 pg/g, 定量限的范围为0.004~0.012 pg/g。测定低限低, 满足痕量分析的要求。
采用本研究建立的同位素稀释GC/HRMS的方法应用于质控样品WMF-02的检测, 平行测定4次, 进行方法的准确度和精密度评价。详细结果如表6, 18种PCBs的检测值都在理论参考值的范围内, 相对标准偏差(relative standard deviation, RSD)为1.0%~7.5% (RSD<10%)。说明本研究的准确度和精密度符合检测要求, 满足痕量分析的要求。
采用本研究建立的同位素稀释-GC/HRMS的方法对实际猪肉样品中18种PCBs进行检测分析结果显示(表7), 猪肉中∑18 PCBs的污染水平范围为1978.9~2530.8 pg/g脂肪, 均低于欧盟法规[41](No.1259/2011)规定的猪肉中∑6 PCBs最高限量值40 ng/g脂肪, 满足美国EPA1668A的要求。
本研究针对猪肉样品中PCBs的测定, 对提取方法和净化方法进行优化设计, 确定其最佳参数, 并结合GC-HRMS, 建立了一种能同时测定猪肉中18种PCBs的同位素稀释-GC-HRMS法。本研究操作简便, 检出限低, 准确度高, 重现性好, 能同时分析18种PCBs, 满足猪肉中PCBs痕量分析的要求, 可为猪肉中PCBs的分析检测的提供参考。但本研究存在一定的不确定性, 受样品基质限制, 未能涵盖所有食品, 后续还可以进一步开展用该方法检测动物源性食品中PCBs的检测工作, 为开展动物源性食品中PCBs的健康风险评估提供数据支撑。
