The enantiomeric fraction of PCB 136 in feces of mice fed with the high fat or the unrefined diet during a 3 day period. All data points are for feces collected from cages housing three (unrefined diet) or four (high fat diet) animals. The enantiomeric fraction of PCB 136 in feces from one cage (white circle) was not determined at day 3 because the PCB 136 levels are below the detection limit.
