Relationship of silver with selenium and mercury in the liver of two species of toothed whales (odontocetes)

Distribution of trace elements in organs of six species of cetaceans from the Ligurian Sea (Mediterranean), and the relationship with stable carbon and nitrogen ratios

“…The number of individuals sampled in each study is also reported. Concentrations expressed as fresh weight in the original literature were converted to dry weight using the factor of 0.25, as suggested by Becker et al (1995). Our data are in agreement with those measured in specimens from Mediterranean: mercury concentrations in muscle and liver of specimens from Atlantic are lower (Law et al, 1991;Das et al, 2003a).…”

Moisture content in Dall's porpoise (Phocoenoides dalli) tissues: a reference base for conversion factors between dry and wet weight trace element concentrations in cetaceans

“…Table 3 shows CF values of each tissue on Dall's porpoise to convert concentration from dry to wet weight basis, as well as a comparison of CF values between Dall's porpoise and other cetacean species. The CF values in liver, kidney and muscle tissue from Dall's porpoise agreed with those from the harbour porpoise (Phocoena phocoena), the white beaked dolphin (Lagenorhynchus albirostris), the long-finned pilot whale (Globicephala melas) and the beluga whale (Delphinapterus leucas), the fin whale (Balaenoptera physalus), the striped dolphin (Stenella coeruleoalba), the bottlenose dolphin (Tursiops truncatus), as well as the sperm whale (Physeter catodon) (Becker et al, 1995;Sanpera et al, 1996;Law 1996;Holsbeek et al, 1999;Meador et al, 1999;Siebert et al, 1999;Capelli et al, 2000;Dam and Bloch, 2000). Also, the present results on heart, lung and spleen of Dall's porpoise are nearly the same as those of corresponding tissues in the striped dolphin (Capelli et al, 2000).…”

Radionuclide Contaminant Burdens in Arctic Marine Mammals Harvested During Subsistence Hunting

“…data), as well as published data (Becker et al, 1995;Mackey et al, 1996), indicate that belugas effectively bioaccumulate silver (and other trace metals) within liver tissue. The mean concentration of elemental silver in the 16 beluga livers we radioassayed was 17.3 µg g -1 ± 11.0 SD, compared, for example, to a mean concentration below 0.1 µg g -1 in ringed seal liver.…”
