EROD Activity (nmol/min/mg Protein) under Each Experiment Condition and Significance of Various Comparisons (Adjusted Using Dunnett’s Test)

Treatment	Dietary Se level
	Low (0.02 ppm)	Adequate (0.2 ppm)	Supplemental (2 ppm)	2-Way ANOVA
Corn oil	0.10 ± 0.02	0.13 ± 0.02	0.11 ± 0.02	n/a
0.2 μmol/kg PCB 126	2.68 ± 0.12*	2.70 ± 0.08*	2.72 ± 0.09*	*
1 μmol/kg PCB 126	2.38 ± 0.22*	2.29 ± 0.16*	2.28 ± 0.10*	*
5 μmol/kg PCB 126	1.26 ± 0.17*	1.08 ± 0.07*	1.22 ± 0.12*	*
2-Way ANOVA	—	n/a	—

Note. Results are expressed as mean ± SEM. Each group contained four to nine animals. One-way ANOVA was used to examine the difference between each PCB 126 level and the corn oil treatment (*). No significant differences between low or supplemental and the adequate dietary Se level were observed. Significance for each factor based on two-way ANOVA is indicated in the bottom margin (Se, #) and in the right margin (PCB, *). The level for significance is 0.05. n/a, not applicable.
