| Abstract | Blubber samples for this study (37) were collected from beached marine mammals in 2008 – 2009. Three blubber samples were taken from each animal (dorsal, lateral, and ventral). The length, species type, sex, and carcass condition were recorded for each animal. We analyzed multiple blubber samples from 7 different marine mammal species (California sea lions n = 7, harbor seals n = 8, Steller sea lions n = 9, harbor porpoises n = 9). We also looked at single blubber samples from a sperm whale, elephant seal, and Dall's porpoise. Lipid residues were extracted from blubber samples using soxhlet extraction. Organochlorines were separated from lipid residues, and PCBS were separated from organochlorine pesticides using liquid chromatography. PCB and pesticide extracts were analyzed on a Varian CP-3800 gas chromatograph equipped with an electron capture detector, CP-8200 AutoSampler, a Star Chromatography Workstation (version 5), and a SPB-608 fused silica capillary column (30 mm x 0.25 mm x 0.25 um film thickness. Differences in mean organochlorine levels between species were determined by using an analysis of variance (ANOVA). |
