The concentrations of ∑PBDEs and ∑PCBs in fat free milk and whole milk.
Data shown are the geometric mean (pg/mL) with geometric standard deviation, of eight brands of milk samples analyzed in triplicate (fat free milk n = 24, whole milk n = 23).
Fig 2.
The concentrations of ∑PBDEs and ∑PCBs with the relative amount of chlorination and bromination.
(A) ∑PBDEs (Tri: BDE-17 and -28, Tetra: BDE-47, -49 and -66; Penta: BDE-85, -95, -99 and -100; Hexa: BDE-153 and -154; Hepta: BDE-183). (B) ∑PCBs (Di: PCB-11; Tetra: PCB-77; Penta: PCB-84, -91, -95, -101 and -118; Hexa: PCB-131, -132, -135, -136, -138, -149 and -153; Hepta: PCB-174, -175, -176 and -180; Octa: PCB-196). Number 1 to 8 represent eight different brands of commercial milk. ‘C’ indicates conventional milk, while ‘O’ indicates organic milk. Data shown are the geometric mean (pg/mL).

∑PBDE and ∑PCB concentrations in organic and conventional milk.
(A) Concentrations based on milk volume (pg/mL). (B) Concentrations based on milk lipid (ng/g lipid). Data shown are the geometric mean with geometric standard deviation of each brand of milk sample analyzed in triplicate (n = 9 for organic brands FFM, n = 8 for organic brands WM, and n = 15 for conventional brands FFM and WM).
