Chlorinated and brominated contaminants including PCBs and PBDEs in minke whales and common dolphins from Korean coastal waters

Accumulation of PAHs and synthetic musk compound in minke whales (Balanoptera acutorostrata) and long‐beaked common dolphins (Delphinus capensis) from Korean coastal waters

“…The overall lipid-normalized concentrations of PAHs and SMCs in blubber from minke whales and common dolphins were approximately three to five times higher than those in liver tissues, except for the PAH levels in minke whales ( p ¼ 0.163). This result is consistent with previous reports of persistent organic pollutants (POPs), such as organochlorines (OCs), and polybrominated diphenyl ethers (PBDEs) [25][26][27][28]. The lipid content in the blubber (40 AE 11%) of both cetacean species was approximately three times higher than the amount found in the liver (12 AE 1.0%).…”

“…The lipid content in the blubber (40 AE 11%) of both cetacean species was approximately three times higher than the amount found in the liver (12 AE 1.0%). Despite lipid normalization of contaminant concentrations, the differences in concentrations between liver tissue and blubber can be attributed to the difference in lipid composition between the tissues [27,28].…”

"New" POPs in marine mammals in Nordic Arctic and NE Atlantic areas during three decades

“…Compared to ∑5PBDEs in blubber from minke whales caught in the Pacific Ocean, Japan, in 1999 (Marsh et al, 2005), mean levels of sum of corresponding PBDE congeners in the present min-ke whales are 2.5 times higher. However, mean of ∑10PBDE levels in blubber from mature minke whales from Iceland 2003-2007 (91 ng/g LW) are three fold lower than in blubber from mature minke whales caught off the Korean coast in 2006 (270 ng/g LW, Moon et al, 2010). In the Korean study PBDE levels in mature males were, however, almost four times higher than the immature males (Moon et al, 2010).…”

The PBDE levels in one of the Norwegian minke whale samples from 1999 was about four times higher than the other samples from that year.…”

Stratification of Lipid Content and Composition in Blubber of Marine Cetacean from Korean Waters

“…국제포경위원회(International Whaling Commission; IWC)가 상업포경을 금지시킨 1986년 이후, 우리나라 근해에 출현하는 고래류의 개체수 는 점차 증가하고 있다 . 이에 따라 고래에 대한 관심이 증가하면서 개체군 분포를 파악하기 위한 목 시조사뿐만 아니라, DNA를 이용한 고래의 종 동정과 고 래류의 체내 유기오염물질에 관련된 연구가 수행되고 있 다 Moon et al 2010b;Moon et al 2010c;Moon et al 2010d;Park et al 2010a;Park et al 2002). 그러나 우리나라 근해에서 이러한 고래의 개체수 증가가 수산자원(고래의 먹이생물) 및 해양생태계에 미칠 영향에 대해서는 아직 알려진 바 가 없다.…”
