PCBs are detected in bladder tissue from developmentally exposed offspring. (A) Mice were exposed to PCBs via the maternal diet throughout gestation and lactation. PCB concentrations were measured in bladder tissue from male offspring at postnatal day (P) 28–31. Results are mean ± SEM sum of the total PCB congeners which were detected in at least one sample, n = 3–4 pools of bladder tissue per dose group. For samples where the congener was not detected above the limit of detection, one half of the LOD value was assigned. *Significantly different from vehicle control as determined using Kruskal-Wallis test followed by Dunn’s multiple comparisons test, p ≤ 0.05.
