Bioaccumulation of immunosuppressive organochlorines like polychlorinated biphenyls (PCBs) may pose a threat to the health and viability of cetacean populations. To investigate possible associations between chronic exposure to PCBs and…


Levels of organochlorine compounds, including PCDDS and PCDFS, in the blubber of cetaceans from the west coast of North America

Jarman, W. M.; Norstrom, R. J.; Muir, D. C. G.; Rosenberg, B.; Simon, M.; Baird, R. W.
Marine Pollution Bulletin (1996)

Levels of organochlorine compounds (PCDD, PCDF, PCB and organochlorine pesticides) were determined in cetaceans collected from the west coast of North America between 1986 and 1989. The samples included gray…


Organochlorines in Indo-Pacific hump-backed dolphins (Sousa chinensis) and finless porpoises (Neophocaena phocaenoides) from Hong Kong

Parsons, E. C. M.; Chan, H. M.
The Marine Biology of the South China Sea (1998)

Blubber samples from eight Indo-Pacific hump-backed dolphins (Sousa chinensis) and eleven finless porpoises (Neophocaena phocaenoides) stranded between 1993 and 1996, in Hong Kong waters, were collected for organochlorine analysis. Levels…


PCBs, cause of death and body condition in harbour porpoises (Phocoena phocoena) from British waters

Kuiken, Thijs; Bennett, Peter M.; Allchin, Colin R.; Kirkwood, James K.; Baker, John R.; Lockyer, Christina H.; Walton, Michael J.; Sheldrick, Martin C.
Aquatic Toxicology (1994)

Polychlorinated biphenyls (PCBs) suppress immunity, and may have exacerbated the effects of recent morbillivirus epizootics in harbour seals (Phoca vitulina) and striped dolphins (Stenella coeruleoalba). To test the hypothesis that…


Temporal variation and biomagnification of organohalogen compounds in finless porpoises (Neophocaena phocaenoides) from the South China Sea

Ramu, Karri; Kajiwara, Natsuko; Lam, Paul K. S.; Jefferson, Thomas A.; Zhou, Kaiya; Tanabe, Shinsuke
Environmental Pollution (2006)

Polybrominated diphenyl ethers (PBDEs) and organochlorine compounds (OCs) were determined in the blubber of male finless porpoises (Neophocaena phocaenoides) collected in 1990 and 2000/01 from the South China Sea. Among…


Status and conservation of facultative freshwater cetaceans in Asia

Smith, B. D.; Jefferson, T. A.
The Raffles Bulletin of Zoology (2002)

Irrawaddy dolphins Orcaella brevirostris and finless porpoises Neophocaena phocaenoides are referred to as facultative freshwater cetaceans because they occupy both fresh- and nearshore marine waters. In Asia, the especially rapid…


Mortality and morbidity of Hong Kong finless porpoises, with emphasis on the role of environmental contaminants

Jefferson, T. A.; Curry, B. E.; Kinoshita, R.
The Raffles Bulletin of Zoology (2002)

Data on causes of death for finless porpoise (Neophocaena phocaenoides) specimens stranded in Hong Kong between 1995 and 2000 were evaluated. We diagnosed several causes of death, including fishing net…


Accumulation and temporal changes of PCDD/Fs and dioxin-like PCBs in finless porpoises (Neophocaena asiaeorientalis) from Korean coastal waters: Tracking the effectiveness of regulation

Jeong, Yunsun; Kim, Sang-Jo; Shin, Kyung-Hoon; Hwang, Seung Yong; An, Yong-Rock; Moon, Hyo-Bang
Marine Pollution Bulletin (2016)

Temporal trend studies are useful to evaluate the effectiveness of regulations on local pollutants. The emission of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and dioxin-like polychlorinated biphenyls (PCBs) has been regulated…
