The objective is to study the relationship between natural seasonal variations in body lipid status of sea migrating Arctic charr and disposition (e.g. tissue distribution)of PCB, particularly in relation to the toxical potential of a certain body burden of PCB.
This is not a National Implementation Plan (NIP) project

Methods & Procedures
- Procedures and methodology used for, e.g., sampling and sample storage, sample pretreatment, extraction and analysis, including which laboratories are involved, references to methods employed, etc.
Fish are contaminated by gastric implantation. Total lipids and lipid composition are analysed by extraction and high-performance thin-layer chromatography. PCB are analysed by cyclohexane extraction and capillary gas chromatography. All analyses are performed at the NILU laboratories either at Kjeller or in Tromsø. EROD activity are quantified by standard methods (Wolkers et al., 1996. Aquat. toxicol., 35: 127-138).
- QA/QC Information (what QA/QC procedures are implemented, laboratories involvment in QA/QC activities, model verification/validation routines, etc.)
PCB analyses in accordence with EU-standard EN 45001.
