In order to assess the exposure to polychlorinated biphenyls (PCB) in children from East- and West-Germany 276 fat tissue samples were analysed. Total PCB concentrations were calculated by means of six PCB congeners: No. 28, 52, 101, 138, 153 and 180. In children from East-Germany the mean total PCB levels amounted to 0.899 mg/kg (median 0.674) and were significantly higher than in children from West-Germany (0.766/0.555 mg/kg; p less than 0.05). Regional differences were only seen within East-Germany. In fat tissue of children with high intake of breast milk (lactation period greater than 12 weeks) PCB levels were significantly elevated compared to those with low intake of mother's milk (lactation period less than 12 weeks). A further reduction of PCB in our environment is necessary so that breast milk can be recommended for sucklings without any restrictions.
为评估德国东部和西部儿童的多氯联苯（PCB）暴露情况，对276份脂肪组织样本进行了分析。通过六种PCB同系物（28号、52号、101号、138号、153号和180号）计算总PCB浓度。德国东部儿童的总PCB平均水平为0.899毫克/千克（中位数0.674），显著高于德国西部儿童（0.766/0.555毫克/千克；p<0.05）。仅在德国东部发现了地区差异。与母乳摄入量低（哺乳期少于12周）的儿童相比，母乳摄入量高（哺乳期大于12周）的儿童脂肪组织中的PCB水平显著升高。有必要进一步降低我们环境中的PCB含量，以便毫无限制地向婴儿推荐母乳。
