^aElimination/depuration rate constants were determined for whole animals if not noted otherwise (please see the respective references for additional details);

^brainbow trout was fed a diet containing Aroclor 1242, 1254 and 1260 (10 μg/g each) plus PCBs 202 and 209 (0.5 μg/g each);

^cco-eluting with PCB 66;

^dco-eluting with PCB 133;

^erainbow trout was either treated with a PCB mixture containing Aroclor 1242, 1254 and 1260 (10 μg/g each) plus PCBs 202 and 209 (0.5 μg/g each) or this PCB mixture supplemented with (A) CYP 1A-inducing PCB congeners 77, 126 and 169 (10 ng/g each) or (B) CYP 2B-inducing PCB congeners 87, 99, 101, 153, 180 and 194 (10 ng/g each);

^fco-eluting with PCB 92;

^grainbow trout was fed a diet containing different levels of PCBs (Aroclor 1254) as well as six polychlorinated dibenzodioxins and dibenzofurans;

^helimination rate constants summarize the range of elimination rate constants determined during summer, fall, winter, spring and annual temperature cycles;

ⁱco-eluting with PCB 153;

^jco-eluting with PCB 132,

^kelimination rate constants summarize the range of elimination rate constants determined at three different doses; NA = no apparent elimination. NS – regression analysis not significant.
