Study of trace elements in organs and tissues of striped dolphins (Stenella coeruleoalba) found dead along the Ligurian coasts (Italy)

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).…”

Study on the contamination of heavy metals and their correlations in mollusks collected from coastal sites along the Chinese Bohai Sea

“…Multivariate analysis methods such as one-way analysis of variance (ANOVA), principal component analysis (PCA), and correlation analysis (bivariate correlations) have been used to extract information from the chemical analysis in order to find the relationships among these heavy metals in organisms (Foster, 1995;Szefer et al, 1998Szefer et al, , 1999bSzefer et al, , 2002Holmes et al, 1998;Lucila Lares et al, 2002;Capelli et al, 2000;Kim, 1995). In this work, the results of chemical analyses were presented as mean T S.E.…”

Trace elements in different species of cetacean from Rio de Janeiro coast

“…7,8 They represent the ultimate biological "sink" for many persistent pollutants 9 and also have been considered good bioindicators of environmental contamination. 10 The analysis of tissues from different species of whales and dolphins has been used as a tool for the assessment of marine pollution by trace elements. 7,8,11 Generally, marine mammals such as cetaceans species present high concentration of these elements in the liver due to the role played by this organ in terms of pollutant bio-transformation, metabolizing nutrients and essential elements as well as removing some non-essential elements and toxins from the bloodstream.…”

“…12 The study of trace elements in marine mammals is in its infancy in Brazil where few studies documented their concentrations in the tissues of cetaceans species with coastal habits such as Sotalia guianensis, Pontoporia blainvillei and oceanic habits such as Stenella frontalis. 7,11,[13][14][15][16][17] Furthermore, extensive studies of As, Cd, Cu, Pb, Se and Ag concentrations in cetaceans have been carried out in Northern Hemisphere 5,8,10,12,[18][19][20][21][22][23][24][25][26][27][28][29][30] but relatively little is known about contaminant levels in Southern Hemisphere cetaceans. [31][32][33][34][35] Then, the present research adds new insight to and complements the existing studies.…”
