Decreases in BDE-47 (A) and PCB-153 (B) levels in breast milk collected by ST participants 6–24 weeks after birth. lw, lipid weight. For BDE-47, only 8 ST participants are shown; the ninth participant had a much higher (542 ng/g lw) initial BDE-47 concentration, but her depuration slope was similar. To illustrate measurement precision, the 8 QCP samples that were analyzed concurrently are plotted, with dotted lines showing 1 SD from the mean.
