Boxplots of contaminant burdens by sex-age class (top) and CDV status (bottom).

<p>Red dashed line indicates proposed threshold for potential toxic effects for ∑TEQ levels (196−220 pg/g lipid weight) derived from experimental studies in harbour seals (De Swart et al. 1994, 1995a, 1995b, 1996, Ross et al. 1995). y axis is plotted on log10 scale.</p>
