我们分析了多氯二苯并对二恶英和相关化合物的母乳中，并估计在日本西部的母乳转移到新生儿的水平。从1994年到1996年，埃塞俄比亚化学品的2，3，7，8-TeCDD当量（TEQ）略有下降。特别是，总PCDDs和总共面PCBs的TEQ的下降高于总PCDFs。在2，3，7，8-TeCDD、1，2，3，7，8-PeCDD、1，2，3，6，7，8-HxCDD、1，2，3，7，8，9-HxCDD、2，3，4，7，8-PeCDF、1，2，3，6，7，8-HxCDF、3，3'，4，4'，5-PeCB和3，3'，4，4'，5，5'-HxCB浓度中，多胎组母乳中的β-半乳糖含量显著低于多胎组（P
We analyzed polychlorinated dibenzo-p-dioxins and related compounds in the breast milk of primiparas and multiparas, and estimated the levels transferred to newborns by breast milk in Western Japan. 2,3,7,8-TeCDD equivalents (TEQ) of the chemicals in primiparas decreased slightly from 1994 to 1996. In particular, decreases of the TEQs of total PCDDs and total coplanar PCBs were higher than that of total PCDFs. In 2,3,7,8-TeCDD, 1,2,3,7,8-PeCDD, 1,2,3,6,7,8-HxCDD, 1,2,3,7,8,9-HxCDD, 2,3,4,7,8-PeCDF, 1,2,3,6,7,8-HxCDF, 3,3',4,4',5-PeCB and 3,3',4,4',5,5'-HxCB concentrations, those in the breast milk of multiparas were significantly lower than those in the breast milk of primiparas (p
