Word Health Organization, WHO/EURO, has coordinated two rounds of follow-up studies on levels of PCDDs, PCDFs, and PCBs in human milk which were analyzed as two pooled samples from each participating country, one from urban and the other one from rural area. Finland has taken part to both of those studies and we are now reporting results of all the second round randomly sampled human milk samples (84 samples) from Southern (20) and Eastern (64) Finland. The levels of PCDD/Fs and PCBs in human milk in Southern Finland were considerably higher than in Eastern Finland. The level of PCDD/Fs in human milk in Southern Finland was the same as in the Central Europe but the level in Eastern Finland was similar to levels in Norway and eastern parts of Europe. The concentrations of PCDD/Fs and PCBs showed a significant decrease from 1987 to 1994. Declining of PCDD/Fs and PCBs was 36 and 49% in primiparae mothers' milk, respectively. This decrease in concentrations of PCDD/F and PCB was slightly greater in Eastern than in Southern Finland.
世界卫生组织欧洲区域办事处（WHO/EURO）协调开展了两轮关于母乳中多氯二苯并二恶英（PCDDs）、多氯二苯并呋喃（PCDFs）和多氯联苯（PCBs）含量的跟踪研究，这些母乳样本是将每个参与国家的两份样本合并而成，一份来自城市地区，另一份来自农村地区。芬兰参与了这两项研究，我们现在报告第二轮从芬兰南部（20份样本）和东部（64份样本）随机抽取的所有母乳样本的研究结果。芬兰南部母乳中PCDD/Fs和PCBs的含量显著高于芬兰东部。芬兰南部母乳中PCDD/Fs的含量与中欧相当，但芬兰东部的含量与挪威及欧洲东部地区的含量相近。1987年至1994年期间，PCDD/Fs和PCBs的浓度显著下降。初产妇母乳中PCDD/Fs和PCBs的降幅分别为36%和49%。芬兰东部PCDD/F和PCB浓度的下降幅度略大于南部。
