Figure
8. Concentrations of sum PCB6 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 PCB6
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<0.02).
