investigation of trophic level and niche partitioning of 7 cetacean species by stable isotopes, and cadmium and arsenic tissue concentrations in the western pacific ocean.a total of 24 stranded or bycatch cetaceans, including balaenoptera omurai, lagenodelphis hosei, kogia sima, stenella attenuata, grampus griseus, neophocaena phocaenoides, and sousa chinensis, were collected from 2001 to 2011 in taiwan. using the muscular δ(13)c and δ(15)n data, three ecological groups were identified as the oceanic baleen whale, the neritic, and the coastal toothed whale groups, coinciding with their taxonomy, feeding habits and geographical distribution. a horizontal inshore t ...201525684592
tissue concentrations of four taiwanese toothed cetaceans indicating the silver and cadmium pollution in the western pacific ocean.muscle, lung, kidney and liver tissues of 45 bycatch and stranded cetaceans, including 14 grampus griseus (gg), 7 kogia simus (ks), 10 lagenodelphis hosei (lh), and 14 stenella attenuata (sa), were collected in the waters off taiwan from 1994 to 1995, and from 2001 to 2012. baseline concentrations (in μgg(-1) dry weight) of the cetaceans were lung (<0.05)=muscle (<0.05)<kidney (0.08±0.04)<liver (0.43±0.28) for ag, and muscle (0.03±0.03)=lung (0.22±0.19)<liver (3.82±3.50)<kidney (16.22±18.81) for ...201728442199
congener-specific polychlorinated biphenyls in cetaceans from taiwan waters.during 2000 to 2001, a total of 73 blubber samples from 13 species of stranded or accidentally captured cetaceans were collected from taiwan coastal waters for polychlorinated biphenyl (pcb) analysis. after homogenization, saponification, liquid-liquid extraction, and silica-gel solid-phase extraction, pcb concentrations were determined by gas chromatography/mass spectrometry. total concentrations of 19 pcb congeners (sigmapcbs) were between 0.23 microg/g lipid weight of risso's dolphin to 33.73 ...200415499506
mercury, organic-mercury and selenium in small cetaceans in taiwanese hg (sigmahg), organic-hg (o-hg) and se bioaccumulations in small cetaceans distributed in taiwanese waters of the taiwan strait and the southwestern pacific have been investigated for the first time. the results could represent the baseline metal concentrations of marine mammals in the southwestern pacific, where volcanic activities are possibly the major source of mercury to the environments. muscle samples of four species of small cetaceans were collected from animals accidentally caught ...200212398391
