Concentrations of trace metals (As, Cd, Cr, Cu, Pb, Hg, Se, and Zn) were determined in the livers, kidneys, muscles, intestines, and hearts of twelve long-beaked common dolphins (Delphinus capensis) from the East Sea, Korea, in 2006. All specimens were entangled in various commercial fishing nets or traps and as such are recorded as by-catch. The concentrations of Cu, Hg, Se, and Zn were much higher in the liver than in the kidney, muscle, intestine, or heart. Trace metals that accumulated in the liver were, in descending order: Zn > Hg > Cd > Se > Cu > As > Cr > Pb. In contrast, the concentration of Cd was higher in the kidney than in any other organs. The trace metals accumulated in the kidney were, in descending order: Cd > Zn > Cu > Hg > Se > As > Pb > Cr. No significant differences were found in the concentrations of As, Cr, or Pb in all the tissues examined. © 2011 Korea Ocean Research & Development Institute (KORDI) and the Korean Society of Oceanography (KSO) and Springer Netherlands.

Olive flounder, Paralichthys olivaceus were exposed to waterborne Cu (control, 50, 80, 150, and 320 μg/L) for 30 days and then depurated for 20 days to investigate the effects of waterborne Cu exposure on growth, accumulation, and elimination. The weight-specific growth rate was significantly negatively related to waterborne Cu concentrations at 150 and 320 μg/L. The order of Cu accumulation in different tissues of exposed fish was liver>intestines>gills>kidneys>muscle, suggesting that the liver is more important than other tissues for the storage of Cu in olive flounder. The accumulation factor for the gills, intestines, liver, and muscle increased with increasing exposure time, and accumulation was negatively related to exposure concentration for the gills, kidneys, and muscle. Cu concentrations in the gills, intestines, and liver continuously decreased for 20 days of depuration. The fastest elimination rate occurred in the intestines at all exposure concentrations, and the order of Cu elimination in the different tissues was intestines>liver>gills. © The Korean Society of Fisheries and Aquatic Science.
