Technical polychlorinated byphenyl (PCB) preparations--Delors 103, 104, 105, and 106--produced in the former Czechoslovakia were analyzed for their chlorobiphenyl (CB), chloronaphthalene (PCN) and chlorinated dibenzofuran (PCDF) composition and content using high resolution gas chromatography-mass spectrometry techniques. The congener patterns of Delors 103, 104, 105, and 106 resembled Aroclors 1242, 1248, 1254, and 1260. Delors contained PCNs and PCDFs, as impurities, at microgram per gram concentrations. Concentrations of PCNs and PCDFs in Delors were greater than those found in the corresponding Aroclors. The potential for the emissions of PCNs and PCDFs from Delor was estimated to be 3680 and 860 kg, respectively. Non- and mono-ortho PCBs were the major contributors to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) equivalents in Delor mixtures.
采用高分辨率气相色谱 - 质谱技术，对在前捷克斯洛伐克生产的工业多氯联苯（PCB）制剂——多氯联苯103、104、105和106——的氯代联苯（CB）、氯代萘（PCN）和氯代二苯并呋喃（PCDF）的组成及含量进行了分析。多氯联苯103、104、105和106的同系物模式类似于多氯联苯混合物1242、1248、1254和1260。多氯联苯制剂含有作为杂质的氯代萘和氯代二苯并呋喃，浓度为每克微克级。多氯联苯制剂中氯代萘和氯代二苯并呋喃的浓度高于相应的多氯联苯混合物中的浓度。据估计，多氯联苯制剂中氯代萘和氯代二苯并呋喃的排放量分别为3680千克和860千克。非邻位和单邻位多氯联苯是多氯联苯制剂混合物中2,3,7,8 - 四氯二苯并 - p - 二噁英（TCDD）当量的主要贡献者。
