Figure
6. Concentrations of sum PCDD/F+dl-PCB in B-cut and I-cut of muscle
from Atlantic halibut sampled in different areas within Norwegian
waters (see figure 1 for geographical location of the different
areas). Median concentrations (columns) and
25 and 75 percentiles (vertical bars) are shown for each area. Mean
values are indicated by triangles. The red line indicates the EU and
Norwegian maximum level for sum PCDD/F+dl-PCB in fish muscle.
Different letters above the columns (a and
b for I-cut, a’ and b’ for B-cut) indicate significant
differences between the areas (one-way ANOVA with log-transformed
concentrations, followed by Tukey post-hoc test, p<0.05)
