Figure 6.
Peak excretion of metabolites in feces and urine occurred within 24 h. Amount of 4′OH-PCB3 recovered from urine and feces from samples collected at different time after exposure showed that a peak excretion occurred from 0 to 12 h in urine and 0–18 h in feces. Peak excretion of sulfates also occurred from within 0–12 h postexposure, which has been published previously.29 No conjugated metabolites were detected in feces at any time point. Values are mean ± SD, n = 3, and are corrected for extraction efficiency.
