Abstract

The concentrations of PCB congeners in the blubber and liver of male and female Steller sea lions (Eumetopias jubatus; SSLs) collected from the Shakotan Peninsula and the Nemuro Strait, Hokkaido, Japan in 2008 and 2010 were measured by HRGC-HRMS, in order to express the concentration profiles in SSLs at these regions. #153 predominated in both organs, followed by #138, #99 and #118. In males, #28 and #31 were concentrated particularly in the blubber, while #177 and #199 were accumulated specifically in the liver. The differences in these concentration profiles might be expressed by the differences in the organs and their functions. The concentrations of #99, #118, #138, #153, and #180 in the blubber appeared to correspond significantly with the differences between genders. The details of the surveys on PCB congeners in SSLs could clarify the differences in the residue levels of individual congeners for organs and genders.

► The concentrations of PCB congeners in SSLs, Hokkaido were measured. ► In males, #28 and #31 were concentrated particularly in the blubber. ► While #177 and #199 were accumulated specifically in the liver of males. ► Between genders, the concentrations of major congeners in the blubber differed. ► Our survey clarified the detail features of PCBs in organs and between genders.
