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…
Concentrations of artificial radionuclide 137Cs and natural radionuclide 40K in Dall's porpoise, Phocoenoides dalli, from the Pacific coast of northern Japan in 1996 are presented. Concentrations of 137Cs in muscle…
Published data on pollutants found in marine mammals from Central and South America are limited. Few species have been studied (18) and sample sizes are usually too small to allow…
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…
A wide range of organochlorine residues were determined in the blubber of harbour porpoises from the Black Sea. Concentrations of DDTs (8.3–180 μg g−1 wet weight) were the highest followed…
Concentrations of butyltin compounds (BTs) were determined in harbour porpoise (Phocoena phocoena) collected from the Turkish coastal waters of the Black Sea. Total butyltin compounds (∑ BTs) in the liver…
From an intensive review of historical records and the examination of stranded cetaceans it was determined that 16 cetacean species have been reported from Hong Kong, including resident populations of…
This paper reviews and summarises published and unpublished information on harbour porpoises in Irish waters and presents results of recent research. Harbour porpoises have been recorded from all Irish coasts…
Harbour porpoises are widely distributed in the seas around Denmark. Total abundance in Danish waters is estimated as approximately 100,000 animals. Population density varies considerably by area. There are probably…
The reported decline of the harbour porpoise in the coastal areas of the North Sea after 1940, has also been seen in Dutch waters. Information on the distribution and abundance…
