FIG. 3.

Tissue levels of PCB 95 (A), Σ₍₅₎OH-PCB 95 (B), PCB 136 (C), and Σ₍₄₎OH-PCB 136 in (D) dams and the corresponding P3, P7, and P21 pups. Values are adjusted for tissue wet weight and presented on a logarithmic scale as mean ± SD of average levels for male and female pups from the same litter (n = 5 or 6 litters; see Supplementary Tables 1 and 2 for additional details). C, carcass; B, brain; L, liver; W, whole blood; M, muscle. *Significantly different from carcass of P3 pups; P < .05. ^# Significantly different from brain of P7 pups; P < .05; ^## significantly different from brain of P7 pups; P < .01. ^$Significantly different from levels in the same tissue from pups euthanized on P21; P < .05.
