Lipid content

Parameter to normalise concentrations of lipophilic substances

Non-polar organic compounds are often persistent and tend to bioaccumulate. Due to their fat solubility (lipophilicity) they are concentrated mainly in the lipid fraction of organisms. Depending on their lipid contents, residue levels may differ considerably between individuals, species and size groups.

Variations in these data often can be reduced when normalising chemical concentrations by lipid content. Furthermore, lipid normalisation facilitates the comparison between species and sites.
