AB  - Contaminant studies in cetaceans can provide information about pollutant levels 
      and patterns in a given region. Due to the confounding effects of reproductive 
      status and maternal offloading in females, these studies typically focus on 
      males. However, an improved understanding of contaminant burdens in female 
      cetaceans is needed to better assess potential impacts to populations. The 
      objectives of this study were to characterize concentrations of persistent 
      organic pollutants (POPs) in blubber of female humpback whales across age classes 
      and to also better characterize maternal offloading of these pollutants to their 
      offspring. A total of 36 blubber biopsy samples of female humpback whales 
      (Megaptera novaeangliae) from the Gulf of Maine were analyzed to examine 
      contaminant loads across females of different ages. Sampled individuals were 
      individually-identified from longitudinal studies and assigned to age class 
      (i.e., adult, subadult, juvenile, calf). Analysis was performed using gas 
      chromatography/mass spectrometry (GC/MS) of POPs including polychlorinated 
      biphenyls (PCBs), dichlorodiphenyltrichloroethanes (DDTs), chlordanes (CHLDs), 
      polybrominated diphenyl ethers (PBDEs), hexachlorocyclohexanes (HCHs). The most 
      abundant POPs were PCB congeners, with summed values ranging from 280 to 
      12,000 ng/g, lipid weight, which is above recent estimates of the threshold for 
      adverse health effects. We found significant differences in mean values between 
      adults and juveniles and between adults and subadults, with the exception of the 
      less persistent HCHs for the latter. We also found significant differences in 
      mean levels of  summation operatorHCHs between the juveniles and subadults. Changes over age are 
      consistent with maternal offloading and potentially important for evaluating 
      population health and viability.
