Abstract:
The objectives of the work were to determine the relationship, if any, between infections of phocine distemper virus (PDV) in seals and their body burdens of contaminants. To this end, broad spectrum survey mode GCMS was to be used to look for a vide range of compound types in extracts of seal blubber, with emphasis on PAHs and Red List compounds such as triazine herbicides, organophosphorus pesticides and trifluralin. Some preliminary extractions and GCMS analyses were carried out. PCB congeners, p,p'-DDE and p,p'-DDT were identified in one of the extracts. However, no other compounds of potential interest were found. An open-ended broad spectrum approach to GCMS analysis of seal blubber is not feasible because of the high lipid content. It is recommended that future work should focus on using isotopically labelled internal standards to develop effective extraction and clean-up methods for some specific target compounds. Candidates for target compounds include triazine herbicides, organophosphorus pesticides, trifluralin, PAHs, nonyl and octylphenols and their mono and diethoxylates, and linear alkylbenzenes.
