Note: ND = Not detected. Residue figures are for muscle, liver, heart, kidney, brain or combinations of these or for eggs, not for fat nor whole carcasses.
Samples vary greatly in size - where they are small the range is given instead of the mean.
Exact comparisons cannot be made: the purpose of the table is to show the order of concentrations found in aquatic ecosystems.
