Concentrations of chlorinated pesticides (p,p'-DDE, lindane), hexachlorobenzene (HCB), sum of polychlorinated biphenyls (PCBs), and PCB congeners in breast milk during lactation and the distribution of the chlorinated compounds in fat tissue, blood serum and breast milk were pursued in five primi- or secundipara from the hinterland of a clinic of gynaecology and obstetrics in Brno in 1993. Capillary gas chromatography with ECD detection was used for the determination of the residues. The concentrations of HCB, lindane, p,p'-DDe, and sum of PCBs ranged from 42.5 to 238.4, from < 1.0 to 7.4 from 231.4 to 557.6, and from 661.3 to 2888.9 micrograms.kg-1 of milk fat, respectively. Seventeen PCB congeners were screened, of which 11 were identified in most of the milk samples (IUPAC numbers 28, 101, 118, 126, 128, 138, 153, 156, 170, 180, 194). Congeners 138, 153, 170, and 180 were the most abundant and their concentrations in microgram.kg-1 of milk fat ranged from 122.9 to 501.0 for 153, from 103.4 to 372.1 for 138, from 66.1 to 407.9 for 180, from 26.8 to 183.1 for 170, and from 10.0 to 41.7 for 118.
1993年，对布尔诺一家妇产科诊所腹地的5名初产妇或经产妇哺乳期母乳中氯化农药（p,p'-滴滴伊、林丹）、六氯苯（HCB）、多氯联苯（PCBs）总量及多氯联苯同系物的浓度，以及这些氯化化合物在脂肪组织、血清和母乳中的分布情况进行了研究。采用带电子捕获检测器的毛细管气相色谱法测定残留量。HCB、林丹、p,p'-滴滴伊和多氯联苯总量的浓度分别为42.5至238.4、<1.0至7.4、231.4至557.6以及661.3至2888.9微克/千克乳脂。筛选了17种多氯联苯同系物，其中11种在大多数母乳样本中被鉴定出来（国际纯粹与应用化学联合会编号28、101、118、126、128、138、153、156、170、180、194）。同系物138、153、170和180含量最高，其在乳脂中的浓度（微克/千克）分别为：153为122.9至501.0，138为103.4至372.1，180为66.1至407.9, 170为26.8至183.1，118为10.0至41.7。
