Concentration of mercury and selenium concentrations in the tissues of five cetacean species from Croatian coastal waters
Mercury and Selenium concentrations were measured in muscle, liver, kidney, spleen and lung tissues of five cetacean species, three dolphin (bottlenose, striped and Risso's dolphins) and two whale species (fin and Cuvier's beaked whales), stranded along the Croatian coast during the period 1999 to 2002. The highest mean concentrations of Hg and Se were measured in liver of Risso's dolphins (246 and 162 μg/g wet weight). Statistically significant differences of Hg concentrations in muscle, spleen and lung and Se in liver and lung of different dolphin species were observed. Mercury levels in liver and spleen and Se levels in liver differed between young and adult bottlenose dolphin. A significant positive correlation between different tissue types for Hg and Se concentrations were observed. In all tissues tested, the lowest Hg and Se concentrations were found in fin whales. Mercury concentrations were positively correlated with Se in all tissues. The results present one of few studies related to lung and spleen tissues in these mammals, particularly in the Adriatic Sea
