TI  - Changes in blubber contaminant concentrations in California sea lions (Zalophus 
      californianus) associated with weight loss and gain during rehabilitation.
PG  - 4181-7
AB  - California sea lions have high levels of persistent organic pollutants (POPs) in 
      their blubber. Animals affected by domoic acid fast and refeed during their 
      rehabilitation. We studied the effect of decreases in total body mass (16 +/- 7% 
      of initial body mass) on blubber POP contaminant concentrations and estimated POP 
      burdens during fasting (12 +/- 5 days) in 19 California sea lions. The effect of 
      refeeding (92 +/- 8% of initial body mass) was also investigated. Significant 
      increases in the concentration of all POPs were found over the mass loss period 
      and decreases during mass gain. A basic mass balance model indicated that the 
      changes did not conform to a simple concentrating and diluting pattern and a 
      proportion of the contaminants were lost from the lipid pool. During mass loss, 
      the lower chlorinated polychlorinated biphenyl congeners, chlordanes, and 
      hexachlorocyclohexanes were lost at a higher rate than the other contaminant 
      classes (particularly polybrominated diphenyl ethers). During mass gain the 
      behavior of all contaminant classes was more consistent with the dilution model. 
      These results indicate the importance of considering the energetic contextwhen 
      sampling blubberfor long-term contaminant monitoring and suggest an initial 
      approach to adjust for such differences.
