Table 4.
Chemical burdens per maximum recommended daily dose (lipid); where relevant, corresponding TEQ (2005) and percent (%) of Tolerable Daily Intake (TDI). Values are presented to two significant figures. Blank squares indicate that values fell below the method level of detection (LOD), which are given as an average concentration for all 11 products (pg/g lipid), whilst grey squares indicate that corresponding congeners were not analysed for that product. Abbreviations used for oil products are: Swisse Krill Oil (SW); Norkrill (Nor); Bio-organics (Bio-O); Blackmores Omega (B-Ω); Bioceuticals (BCT); Blackmores Joint (B-Joint); Nature’s Way Kidsmart (NWK); Blackmores Pregnancy (B-P); Nature’s Own 1000 mg (NO-1000); Blackmore’s 1000mg (B-1000); Cenovis 1000 mg (C-1000). Capsules or subsamples from two separate batches of each product were pooled for each POP analysis, except for Blackmores Omega Liquid Fish Oil for which only a single batch number could be sourced.
