摘要: Abstract Levels of 24 organochlorine compounds, including toxic mono- ortho PCB congeners, were determined in the organs and tissues (blubber, kidney, lung, muscle, liver, heart) 13 common bottlenose dolphins ( Tursiops truncatus ) stranded between 2000 2005 northern part Croatian territorial waters Adriatic Sea. Polychlorinated biphenyls (PCBs) found at higher concentrations comparison with pesticides (OCPs) all analyzed tissues. Sums six indicator congeners (Σ6PCB) constituted around 50% total amount, while PCB-153 PCB-138 to have highest concentrations. Among seven investigated OCPs, p , ′-DDE was In blubber, mean values 22,048 11,310 ng g −1 wet weight for ΣPCB ΣDDT, respectively. Much lower muscle samples, followed by similar kidneys, liver heart, lowest levels contaminants lungs. The results indicate that ′-DDT is still being introduced Mediterranean region. are among this region toxicological assessments health specie high risk.
