Multi-year assessment (2006–2015) of persistent organic pollutant
concentrations in blubber and muscle from Western Arctic bowhead
whales (*Balaena
mysticetus*), North Slope, Alaska

Abstract:

Blubber and muscle were collected from male bowhead whales (*n* = 71)
landed near Utqiaġvik (Barrow), Alaska, between 2006 and 2015 and analyzed
for lipid content and concentrations of persistent organic pollutants
(POPs) in order to determine levels and trends over the collection period.
Collection year was a significant predictor of blubber concentrations for
most classes of POPs, while for a few classes, animal length (proxy for
age) was also a significant predictor. This is the first report on levels
of PBDEs in bowhead whales; concentrations of these compounds are low
(≤55 ng/g wet weight). Blubber concentrations were lower than those
reported in samples collected between 1992 and 2000, and many POP classes
in blubber declined significantly between 2006 and 2015. Concentrations of
POPs in bowhead whale tissues, which are subsistence foods for Native
Alaskan communities, appear to be declining at rates comparable with
previously reported temporal trends in Arctic biota.
