Legend: n: Total number of samples, LOD Limit of detection, % >LOD: Percentage of samples with concentrations above the LOD, Min. – Max.: Minimum and maximum concentrations. Levels of statistical significance; n.s: Not significant, *: p< 0.05. Note (compounds not included in the table): Concentrations of the congeners t-CD, c-CD, c-NC and TOX-26 were below the limit of detection (< LOD) in all samples from meat, liver, tallow and bone marrow, whereas Mirex was only detected in samples from liver. Heptachlor was not detected in samples from meat and liver. Arithmetic (AM) and geometric (GM) means were not calculated in cases where percentage of samples over LOD were <50%.
