| Abbreviations: HpCDD, heptachlorodibenzo-p-dioxin; HpCDF, heptachlorodibenzofuran; HxCDD, hexachlorodibenzo-p-dioxin; HxCDF, hexachlorodibenzofuran; LOD, limit of detection; OCDD, octachlorodibenzo-p-dioxin; PCB, polychlorinated biphenyl; PeCDD, pentachlorodibenzo-p-dioxin; PeCDF, pentachlorodibenzofuran; TCDD, tetrachlorodibenzo-p-dioxin; TCDF, tetrachlorodibenzofuran; TEQ, toxic equivalent.aLODs are represented as a range because they vary by sample volume, which differed among participants. bUnits are picograms per gram lipid for PCB-126, PCB-169, dioxins, and furans; and nanograms per gram lipid for other PCBs. | ||||||
