| In this study the toxic effects of mercury (Hg) on the histology of the liver of reared spotted scat (Scatophagusargus L.) was investigated. The experiment was conducted to identify the metal concentration in liver after exposure andeffectofexposure period on histological changes of liver in exposed fish. Selected fish were exposed to 10, 20 and 30 ppbconcentrations of mercury for three short-term exposure periods, 24, 48 and 72 hours.Our results revealed similar histological changes in the livers of fishes exposed to different concentrations of metal and in different times. The histological changes were hyalinization, hepatocytesvacuolation, cellular swelling, necrosis, vacuolar degeneration and congestion of blood vessels. However, the intensity of these histological changes was correlated with the extent of metal concentration and the exposure period. |
