Potential Relation Between Mercury Concentrations and Necropsy Findings in Cetaceans from sGerman Waters of the North and Baltic Seas

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).…”

“…Finally we recommend that researchers working on the accumulation and toxicity of trace elements in marine mammals should present moisture content data or CF values in their papers as basic information, which will facilitate comparison with studies on other cetacean species and tissues.

“…Frodello et al, 2000) or different values of CF (e.g. Siebert et al, 1999) have been utilized to convert the concentrations in different tissues.…”

Baseline study of perfluorochemicals in harbour porpoises (Phocoena phocoena) from Northern Europe

“…Declines in porpoise populations may also be directly related to habitat loss (e.g. coastal development), prey depletion from commercial fishery and pollution (Jepson et al, 1999;Siebert et al, 1999;Johnston, 2002). Previous studies on organochlorinated contaminants reported high concentrations in harbour porpoises from Danish and Scandinavian waters (Clausen and Andersen, 1988;Kleivane et al, 1995), the Baltic Sea (Berggrena et al, 1999) and the Southern North Sea (Covaci et al, 2002).…”
