The isomer specific composition of 13 technical PCB formulations of different origin and of pine needles was analyzed using GC/MS and HRGC/HRMS. Nonachlorinated biphenyls were identified in 11 among 13 formulations analyzed, with the highest abundance found for highly chlorinated ones (Aroclors 1268 and 1260, Chlorofen, Sovol, Kanechlors 600 and 500, Delor 106, Clophen A60). Decachlorobiphenyl was identified only in Aroclor 1268, Clophen A60, Aroclor 1260 and Chlorofen, comprising, respectively, 8.9, 2.8, 1.3 and 0.82% of the total bulk of nona- and decaCBs detected. Nona- and decaCB were detected in pine needles in Poland with the highest concentrations found at the sites neighboring to a former production sites of the Polish PCB formulations, while in pine needles collected around the Tokyo Bay nona- and decacCB were detected only in four of 10 sites and the concentrations corresponded to those found at the rural areas of Poland.
采用气相色谱/质谱联用仪（GC/MS）和高分辨气相色谱/高分辨质谱联用仪（HRGC/HRMS）分析了13种不同来源的多氯联苯（PCB）工业制剂及松针的异构体特定组成。在所分析的13种制剂中，有11种鉴定出了九氯联苯，其中高氯代产品（Aroclors 1268和1260、Chlorofen、Sovol、Kanechlors 600和500、Delor 106、Clophen A60）含量最高。仅在Aroclor 1268、Clophen A60、Aroclor 1260和Chlorofen中鉴定出了十氯联苯，分别占所检测到的九氯联苯和十氯联苯总量的8.9%、2.8%、1.3%和0.82%。在波兰的松针中检测到了九氯联苯和十氯联苯，在靠近波兰PCB制剂原生产场地的地点浓度最高，而在东京湾周边采集的松针中，仅在10个地点中的4个检测到了九氯联苯和十氯联苯，其浓度与波兰农村地区的浓度相当。
