  1. Polychlorinated dibenzo-p-dioxins and related compounds in breast milk of japanese primiparas and multiparas.

    Article - En anglais

    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 Westem Japan. 2,3,7,8-TeCDD equivalents (TEQ) of the chemical 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<0.05, lipid basis).

    Based on the assumption that newborns ingest 120 g of breast milk per kg body weight per day, the amounts converted to TEQ values were 121 pg/kg/day (primiparas) and 97.2 pg/kg/day (multiparas).
