| a review of heavy metal and organochlorine levels in marine mammals in australia. | study of toxic contaminants in marine mammal specimens collected around australia is currently uncoordinated and piecemeal. most states collect samples but there is little or no financial support for their analysis. this study combines data, published or unpublished, from 13 sources. heavy metals have been analysed in about 676 specimens; over 400 were for mercury levels in p. macrocephalus taken at a whaling station. the remaining samples were mostly from toothed whales, a few baleen whales (< ... | 1994 | 7973602 |
| eighteen-year study of south australian dolphins shows variation in lung nematodes by season, year, age class, and location. | between 1990 and 2007, carcasses of opportunistically collected short-beaked common dolphins (delphinus delphis; n=238), indo-pacific bottlenose dolphins (tursiops aduncus; n=167), and common bottlenose dolphins (tursiops truncatus; n=15) were examined for parasites and life history data. three species of lung nematodes (halocercus lagenorhynchi, stenurus ovatus, pharurus alatus) were identified in surface nodules, subsurface lesions, or airways. nematode burdens were light to heavy and, in many ... | 2010 | 20688641 |
| metals and selenium in the liver and bone of three dolphin species from south australia, 1988-2004. | metal and selenium concentrations (wet weight) were determined in the liver (cd, hg, pb, zn, cu and se) and bone (pb and cd) of common dolphins (delphinus delphis, n=71) and bottlenose dolphins (tursiops truncatus, n=12, and tursiops aduncus, n=71) stranded or by-caught in south australia from 1988 to 2004. differences in metal burdens existed between species, stranding location, and relative age. t. aduncus had the greatest mean tissue burdens of liver pb (0.45 mg/kg), cd (6.45 mg/kg), hg (475. ... | 2008 | 18006044 |
