Concentrations of 17 toxic 2,3,7,8-chlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and of 36 polychlorinated biphenyl congeners (PCBs) were analyzed from 167 randomly sampled human milk samples from Southern (77 samples) and Eastern (90) Finland. The level of PCDD/Fs and PCBs in human milk in Southern Finland was about 25% higher than those from Eastern Finland. The level of PCDD/Fs in human milk in Finland was the same as in Sweden, 30-50% lower than in milk from Central Europe but about 45% higher than values from Norway or Russia. The PCB concentrations in Southern Finland were at the same level as in the Netherlands, and in Eastern Finland at the same level as in Norway. The levels of PCDD/Fs and PCBs decreased with increasing number of children: the third child was exposed to about 70% of the amount of PCDD/Fs and PCBs as compared with the first child, and the eighth to tenth child to about 20%. The congener patterns of PCDD/Fs and PCBs in Finnish human milk were similar to the countries of Central Europe, however, the levels of penta- and heptachlorinated furans were slightly higher than in milk from other countries.
对来自芬兰南部（77份样本）和东部（90份样本）的167份随机采集的母乳样本，分析了17种有毒的2,3,7,8-氯代二苯并-对-二噁英和二苯并呋喃（PCDD/Fs）以及36种多氯联苯同系物（PCBs）的浓度。芬兰南部母乳中PCDD/Fs和PCBs的含量比芬兰东部约高25%。芬兰母乳中PCDD/Fs的含量与瑞典相同，比中欧母乳中的含量低30%-50%，但比挪威或俄罗斯的值高约45%。芬兰南部的PCB浓度与荷兰处于同一水平，芬兰东部与挪威处于同一水平。PCDD/Fs和PCBs的含量随着孩子数量的增加而降低：与第一个孩子相比，第三个孩子接触的PCDD/Fs和PCBs量约为70%，第八至第十个孩子约为20%。芬兰母乳中PCDD/Fs和PCBs的同系物模式与中欧国家相似，然而，五氯和七氯呋喃的含量略高于其他国家的母乳。
